Located in the Mojave Desert 40 miles southwest of Las Vegas, The Ivanpah Solar Power Facility is a solar thermal power project, currently under construction, with a planned capacity of 392 megawatts, enough to power approximately 140,000 houses. It will deploy 170,000 heliostat mirrors spread over 4,000 hectares, focusing solar energy on boilers located atop three solar power towers, generating steam to drive specially adapted steam turbines The project, developed by Bechtel, will cost $2.2 billion and be the largest solar farm in the world (photo Gilles Mingasson/Getty Images for Bechtel).",

Or would it perish, torn apart by tidal forces and cooked beyond an inch of its life?\u003c/p>\n\u003cp>Speculation is over, and the result is that ISON has disintegrated and is now at best only so much debris drifting back toward deep space.\u003c/p>\n\u003cp>Though we don’t have a comet of the century to enjoy this holiday season, ISON was by no means a failure. Far from it. \u003ca title=\"Comet ISON Postmortem - Phil Plait\" href=\"http://www.slate.com/blogs/bad_astronomy/2013/12/01/comet_ison_post_mortem.html\" target=\"_blank\" rel=\"noopener\">ISON’s ultimately fatal close approach\u003c/a> to the sun was a chance for us to witness and study more than just a pretty veil of gas and dust shed from a comet’s outer layers. It has literally been a comet dissection.\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>An array of Earth-and space-based telescopes (plus Mars Reconnaissance Orbiter out at Mars, ISON’s first port of call in the inner solar system) were able to observe ISON from when it was still more or less a pristine frozen nucleus of primordial ices left over from the solar system’s formation all the way to a very close perihelion. Along the way, ISON surprised us with sudden, unexpected outbursts of gas, and finally a complete breakup, \u003ca title=\"Comet ISON's demise caught on video\" href=\"http://www.nasa.gov/content/goddard/nasa-investigating-the-life-of-comet-ison/#.Uqd4_dJDt8E\" target=\"_blank\" rel=\"noopener\">all caught on video\u003c/a> by the European SOHO and NASA’s STEREO spacecraft.\u003c/p>\n\u003cp>It must have been an incredible sight. Can you imagine a mountain-sized ball of ice completely breaking up and vaporizing in only a few days’ time? If Hollywood were to make this dramatic breakup into a movie, they probably could not go over the top with special effects.\u003c/p>\n\u003cp>Though there may be little to nothing left of ISON to latch our eyes and telescopes onto, ISON’s departure hasn’t left us with empty skies.\u003c/p>\n\u003cp>Another comet, \u003ca title=\"Comet C/2013 R1 Lovejoy\" href=\"http://www.sci-news.com/space/science-c2013r1-comet-lovejoy-01607.html\" target=\"_blank\" rel=\"noopener\">C/2013 R1 Lovejoy\u003c/a>, has been quietly shadowing its media-hog cousin ISON. Discovered only in September Lovejoy has already made its closest approach to Earth, back on November 19th, but has yet to reach perihelion, which takes place on December 22nd.\u003c/p>\n\u003cp>Whereas ISON’s perihelion on Thanksgiving was a harrowing 730,000 miles from the sun’s surface (less than one solar diameter), Lovejoy’s is a more sober 75 million miles—not even within Venus’ orbit. At this distance Lovejoy isn’t in any danger of breaking up or being vaporized, but also isn’t enjoying as much sunlight or media attention as ISON did.\u003c/p>\n\u003cp>In a way, Lovejoy is the mythical Daedalus to ISON’s Icarus. In the Greek myth, Daedalus was a master craftsman, and along with his son, Icarus, was imprisoned on Crete by King Minos. Daedalus constructed two sets of wings from feathers and wax for himself and Icarus so that they could escape (think Iron Man and hang-gliders.) Daedalus cautioned his son not to fly too close to the sun, but Icarus, giddy with the ability to fly, ignored the advice. The sun melted his wings and he plummeted into the sea and drowned. The wiser and more level headed Daedalus kept his distance from the sun and flew a safe course to freedom.\u003c/p>\n\u003cp>Speaking of sun-grazing comets and mythical flying figures, there is a sun-grazer of a third variety making its presence known this month: \u003ca title=\"3200 Phaeton\" href=\"http://science.nasa.gov/science-news/science-at-nasa/2013/27nov_rockcomet/\" target=\"_blank\" rel=\"noopener\">3200 Phaethon—a “rock comet.”\u003c/a>\u003c/p>\n\u003cp>In Greek myth, Phaethon was the son of the sun god, Helios. Wanting recognition as the son of a deity, Phaethon was given the keys to his dad’s chariot, but ended up driving so recklessly that he put the entire Earth in peril—so dad was forced to end the joy ride with a thunderbolt.\u003c/p>\n\u003cp>3200 Phaethon is a sun-grazing asteroid that produces outbursts of dust as it orbits, leaving behind a trail of dust much as a comet does. Exactly how it sheds dust particles isn’t clearly understood, but may have something to do with the solar heating of hydrated minerals that outgas water vapor and carry dust with it.\u003c/p>\n\u003cp>When Earth passes through 3200 Phaeton’s dust trail, which it is currently doing, we enjoy the annual Geminid meteor shower, which reaches a peak in meteor activity on December 13/14 this year. Ordinarily we associate meteor showers with Earth’s passage through the dust trails of comets, so the Geminid shower has added value as originating from a mysterious object that blurs the distinction between comets and asteroids.\u003c/p>\n\u003cp>\u003c/p>\n\u003cp>The good news is, unlike Phaeton the reckless teen of myth, Phaeton the rock-comet poses no danger to the Earth.\u003c/p>\n\n",

Far from it. \u003ca title=\"Comet ISON Postmortem - Phil Plait\" href=\"http://www.slate.com/blogs/bad_astronomy/2013/12/01/comet_ison_post_mortem.html\" target=\"_blank\" rel=\"noopener\">ISON’s ultimately fatal close approach\u003c/a> to the sun was a chance for us to witness and study more than just a pretty veil of gas and dust shed from a comet’s outer layers.

Along the way, ISON surprised us with sudden, unexpected outbursts of gas, and finally a complete breakup, \u003ca title=\"Comet ISON's demise caught on video\" href=\"http://www.nasa.gov/content/goddard/nasa-investigating-the-life-of-comet-ison/#.Uqd4_dJDt8E\" target=\"_blank\" rel=\"noopener\">all caught on video\u003c/a> by the European SOHO and NASA’s STEREO spacecraft.\u003c/p>\n\u003cp>It must have been an incredible sight. Can you imagine a mountain-sized ball of ice completely breaking up and vaporizing in only a few days’ time? If Hollywood were to make this dramatic breakup into a movie, they probably could not go over the top with special effects.\u003c/p>\n\u003cp>Though there may be little to nothing left of ISON to latch our eyes and telescopes onto, ISON’s departure hasn’t left us with empty skies.\u003c/p>\n\u003cp>Another comet, \u003ca title=\"Comet C/2013 R1 Lovejoy\" href=\"http://www.sci-news.com/space/science-c2013r1-comet-lovejoy-01607.html\" target=\"_blank\" rel=\"noopener\">C/2013 R1 Lovejoy\u003c/a>, has been quietly shadowing its media-hog cousin ISON. Discovered only in September Lovejoy has already made its closest approach to Earth, back on November 19th, but has yet to reach perihelion, which takes place on December 22nd.\u003c/p>\n\u003cp>Whereas ISON’s perihelion on Thanksgiving was a harrowing 730,000 miles from the sun’s surface (less than one solar diameter), Lovejoy’s is a more sober 75 million miles—not even within Venus’ orbit. At this distance Lovejoy isn’t in any danger of breaking up or being vaporized, but also isn’t enjoying as much sunlight or media attention as ISON did.\u003c/p>\n\u003cp>In a way, Lovejoy is the mythical Daedalus to ISON’s Icarus. In the Greek myth, Daedalus was a master craftsman, and along with his son, Icarus, was imprisoned on Crete by King Minos. Daedalus constructed two sets of wings from feathers and wax for himself and Icarus so that they could escape (think Iron Man and hang-gliders.) Daedalus cautioned his son not to fly too close to the sun, but Icarus, giddy with the ability to fly, ignored the advice. The sun melted his wings and he plummeted into the sea and drowned. The wiser and more level headed Daedalus kept his distance from the sun and flew a safe course to freedom.\u003c/p>\n\u003cp>Speaking of sun-grazing comets and mythical flying figures, there is a sun-grazer of a third variety making its presence known this month: \u003ca title=\"3200 Phaeton\" href=\"http://science.nasa.gov/science-news/science-at-nasa/2013/27nov_rockcomet/\" target=\"_blank\" rel=\"noopener\">3200 Phaethon—a “rock comet.”\u003c/a>\u003c/p>\n\u003cp>In Greek myth, Phaethon was the son of the sun god, Helios. Wanting recognition as the son of a deity, Phaethon was given the keys to his dad’s chariot, but ended up driving so recklessly that he put the entire Earth in peril—so dad was forced to end the joy ride with a thunderbolt.\u003c/p>\n\u003cp>3200 Phaethon is a sun-grazing asteroid that produces outbursts of dust as it orbits, leaving behind a trail of dust much as a comet does. Exactly how it sheds dust particles isn’t clearly understood, but may have something to do with the solar heating of hydrated minerals that outgas water vapor and carry dust with it.\u003c/p>\n\u003cp>When Earth passes through 3200 Phaeton’s dust trail, which it is currently doing, we enjoy the annual Geminid meteor shower, which reaches a peak in meteor activity on December 13/14 this year. Ordinarily we associate meteor showers with Earth’s passage through the dust trails of comets, so the Geminid shower has added value as originating from a mysterious object that blurs the distinction between comets and asteroids.\u003c/p>\n\u003cp>\u003c/p>\n\u003cp>The good news is, unlike Phaeton the reckless teen of myth, Phaeton the rock-comet poses no danger to the Earth.\u003c/p>\n\n\u003c/div>\u003c/p>",

That’s more speculative.\u003c/p>\n\u003cp>But it’s certainly something that gives us an extra interest in comets: The idea that comets could be the frozen delivery system of, not life itself, but some of the chemical building blocks of life.\u003c/p>\n\u003cfigure id=\"attachment_11584\" class=\"wp-caption aligncenter\" style=\"max-width: 1024px\">\u003ca href=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/cISON-Nov14-2013-11x50sec-iso3200-8bt-CombineFilesAdpHDRAddv2Bv1jpsmcrop-1024x710.jpg\" rel=\"attachment wp-att-11584\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-11584\" src=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/cISON-Nov14-2013-11x50sec-iso3200-8bt-CombineFilesAdpHDRAddv2Bv1jpsmcrop-1024x710.jpg\" alt=\"Comet ISON on November 14 (Chabot Space & Science Center/Conrad Jung)\" width=\"1024\" height=\"710\">\u003c/a>\u003cfigcaption class=\"wp-caption-text\">Comet ISON on November 14 (Chabot Space & Science Center/Conrad Jung)\u003c/figcaption>\u003c/figure>\n\u003cp>\u003c/p>\u003c/div>",

Hundreds of wealthy would-be space tourists have put down deposits for a $250,000 rocketship ride into the edge of space, with Virgin Galactic’s flights scheduled to begin as early as 2015. The tragedy capped a tumultuous week for private space ventures, with the explosion a few days earlier of an unmanned Orbital Sciences rocket just moments after takeoff from Wallops Island in Virginia. Investigations are ongoing into the cause of both accidents. For more information, read the \u003ca href=\"http://ww2.kqed.org/news/2014/10/31/virgin-galactics-spaceshiptwo-destroyed-in-test-flight\">KQED News Fix blog post\u003c/a>. \u003c/em>\u003c/p>\n\u003cp>In May 2012, \u003ca href=\"http://spacex.com/\">SpaceX\u003c/a> became the first company to make a commercial mission to the International Space Station, successfully ferrying more than 1,000 pounds of supplies to the station. But SpaceX’s founder and CEO, billionaire entrepreneur Elon Musk, has a larger prize in mind: flying people to Mars aboard SpaceX rockets within 10 or 15 years.\u003c/p>\n\u003cp>Meanwhile, \u003ca href=\"http://www.virgingalactic.com/\">Virgin Galactic\u003c/a>, founded by billionaire British entrepreneur Richard Branson, is on track to launch its first commercial spacecraft next year, rocketing “space tourists” on a $250,000 ride to the edge of space. So far, the company has collected deposits from more than 600 passengers, including wealthy children of the space age and celebrities like Justin Bieber and Leonardo DiCaprio.\u003c/p>\n\u003cp>Today’s space exploration efforts look far different than the historic exploration of space pioneered by \u003ca href=\"http://www.nasa.gov/\">NASA\u003c/a> during the Apollo missions of the 1960s and ’70s. Then, during the height of the Cold War, the US locked technological and ideological horns with the Soviet Union to prove that American ingenuity and technological prowess would triumph in the race to land a man on the moon.\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>But now, in the age of cutbacks and federal furloughs, NASA is turning to the private sector to more cheaply get to Low Earth Orbit, a region roughly 100 to 600 miles above earth where the \u003ca href=\"http://www.nasa.gov/mission_pages/station/main/\">International Space Station\u003c/a> is located. From space tourism to plans to mine the moon, dozens of for-profit companies, many with the business models, characters and the high-tech, risk-taking culture of Silicon Valley, are reshaping American space exploration.\u003c/p>\n\u003cp>Stanford Aeronautics Professor G. Scott Hubbard, who worked at NASA for 20 years, and served as the director at one of its centers, the NASA Ames Research Center, said the space agency’s growing partnership with the private sector is critical for America to work more efficiently and cheaply in space.\u003c/p>\n\u003cp>“In the old days, with all of these specifications, the reviews would get down to every nut and bolt,” he said. “In this new age, now, in ‘new space’, companies like SpaceX, like \u003ca href=\"http://www.orbital.com/\">Orbital Sciences\u003c/a>, are building their own vehicles, and NASA is saying, ‘OK, if you give us a service meeting this type of a milestone and this level of reliability, we’ll just take it…we’re not going to investigate every nut and bolt.'”\u003c/p>\n\u003cfigure id=\"attachment_11241\" class=\"wp-caption alignleft\" style=\"max-width: 640px\">\u003ca href=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/703_KQEDSci_Space_JRoy_GShotwell_19563123.jpg\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"wp-image-11241\" src=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/703_KQEDSci_Space_JRoy_GShotwell_19563123.jpg\" alt=\"Gwynne Shotwell, President and COO of SpaceX, shows off rocket engines being built at the company's headquarters near L.A.

Image by Jayme Roy\u003c/figcaption>\u003c/figure>\n\u003cp>But the private sector isn’t simply providing lower-cost services to NASA. More fundamentally, it is disrupting the space industry by creating new technologies that make getting into space cheaper. And that is expanding the commercial, scientific and even extreme adventure possibilities of space.\u003c/p>\n\u003cp>Many of the country’s new space entrepreneurs hail from the tech sector and some, like Elon Musk, rocketed to prominence with startup success in the early days of e-commerce.\u003c/p>\n\u003cp>“Elon Musk didn’t come from an aerospace background, he is a computer scientist by training,” said Silicon Valley venture capitalist Steve Jurvetson, a SpaceX board member and investor in the company. “And he thinks about the rocket like computer scientists would – modular reuse, modern programming languages, everything.”\u003c/p>\n\u003cp>Clearly, there are risks associated with these new, for-profit space ventures. Not only does the threat of commercial failure loom large, so too is the threat of accidents aboard the rocket ships gearing up to fly wealthy thrill-seekers and space buffs dozens of miles above earth.\u003c/p>\n\u003cp>“If we fly in space often enough, people will die. That’s not a pleasant truth but it is the truth,” said Jeff Greason, CEO of \u003ca href=\"http://www.xcor.com/\">XCOR Aerospace\u003c/a>, a Mojave, California company that, like Virgin Galactic, is also accepting deposits for rides aboard its rocket ship.\u003c/p>\n\u003cp>Tragically, this sentiment became reality on Oct. 31, 2014, when Virgin Galactic’s SpaceShipTwo crashed during a test flight, killing Michael Alsbury, a Scotts Valley native and one of the two pilots on board.\u003c/p>\n\u003cp>The disaster came just three days after the explosion of an unmanned Orbital Sciences rocket in Virginia. The rocket was scheduled to make a resupply mission to the International Space Station, as part of NASA’s Commercial Crew and Cargo program, under which the company, along with its competitor, SpaceX, had won lucrative, billion-dollar contracts to haul cargo to and from the ISS.\u003c/p>\n\u003cp>Hubbard said the disasters occurred in two different areas of the private space sector, so the impact of the crashes should be examined separately.\u003c/p>\n\u003cp>“NASA’s commercial cargo and crew program represents one industry and it has almost nothing to do with the Virgin Galactic crash, which has to do with suborbital space tourism,” Hubbard said. “Orbital Sciences will have to stand down and evaluate their vehicle until they fly again. I don’t see NASA deviating in any substantial way from their commercial cargo and commercial crew program.”\u003c/p>\n\u003cp>Hubbard served as the sole NASA official on the investigation into the February 2003 crash of the Space Shuttle Columbia, which killed all seven crew members.\u003c/p>\n\u003cp>He said he thinks that the crash of SpaceShipTwo will not derail the launch of space tourism, adding that the risks are not unlike those of the early days of aviation.\u003c/p>\n\u003cp>“I think within the next five years, you will see space tourism,” he said. “Flying cross country is safer per seat mille that it is per seat mile driving in your car, but that occurred over a period of 100 years, from Kitty Hawk to now.”\u003c/p>\n\u003cp>“And I think Richard Branson will need to restore the faith of his paying customers that he has a safe operation,” he added. “But I don’t see the interest in suborbital space tourism going away.”\u003c/p>\n\u003cp>As Orbital Sciences and Virgin Galactic struggle to move on from their setbacks, other private space companies have seen major successes in recent months.\u003cs>\u003c/s>\u003c/p>\n\u003cfigure id=\"attachment_11239\" class=\"wp-caption alignleft\" style=\"max-width: 640px\">\u003ca href=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/703_KQEDSci_Space_BMcHugh_Skybox_07343803_2.jpg\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-11239\" src=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/703_KQEDSci_Space_BMcHugh_Skybox_07343803_2.jpg\" alt=\"Technicians at Skybox Imaging work on a satellite in a clean room at the company's headquarters in Mountain View.

Hundreds of wealthy would-be space tourists have put down deposits for a $250,000 rocketship ride into the edge of space, with Virgin Galactic’s flights scheduled to begin as early as 2015. The tragedy capped a tumultuous week for private space ventures, with the explosion a few days earlier of an unmanned Orbital Sciences rocket just moments after takeoff from Wallops Island in Virginia. Investigations are ongoing into the cause of both accidents. For more information, read the \u003ca href=\"http://ww2.kqed.org/news/2014/10/31/virgin-galactics-spaceshiptwo-destroyed-in-test-flight\">KQED News Fix blog post\u003c/a>. \u003c/em>\u003c/p>\n\u003cp>In May 2012, \u003ca href=\"http://spacex.com/\">SpaceX\u003c/a> became the first company to make a commercial mission to the International Space Station, successfully ferrying more than 1,000 pounds of supplies to the station. But SpaceX’s founder and CEO, billionaire entrepreneur Elon Musk, has a larger prize in mind: flying people to Mars aboard SpaceX rockets within 10 or 15 years.\u003c/p>\n\u003cp>Meanwhile, \u003ca href=\"http://www.virgingalactic.com/\">Virgin Galactic\u003c/a>, founded by billionaire British entrepreneur Richard Branson, is on track to launch its first commercial spacecraft next year, rocketing “space tourists” on a $250,000 ride to the edge of space. So far, the company has collected deposits from more than 600 passengers, including wealthy children of the space age and celebrities like Justin Bieber and Leonardo DiCaprio.\u003c/p>\n\u003cp>Today’s space exploration efforts look far different than the historic exploration of space pioneered by \u003ca href=\"http://www.nasa.gov/\">NASA\u003c/a> during the Apollo missions of the 1960s and ’70s. Then, during the height of the Cold War, the US locked technological and ideological horns with the Soviet Union to prove that American ingenuity and technological prowess would triumph in the race to land a man on the moon.\u003c/p>\n\u003cp>\u003c/p>\u003c/div>",

From space tourism to plans to mine the moon, dozens of for-profit companies, many with the business models, characters and the high-tech, risk-taking culture of Silicon Valley, are reshaping American space exploration.\u003c/p>\n\u003cp>Stanford Aeronautics Professor G. Scott Hubbard, who worked at NASA for 20 years, and served as the director at one of its centers, the NASA Ames Research Center, said the space agency’s growing partnership with the private sector is critical for America to work more efficiently and cheaply in space.\u003c/p>\n\u003cp>“In the old days, with all of these specifications, the reviews would get down to every nut and bolt,” he said. “In this new age, now, in ‘new space’, companies like SpaceX, like \u003ca href=\"http://www.orbital.com/\">Orbital Sciences\u003c/a>, are building their own vehicles, and NASA is saying, ‘OK, if you give us a service meeting this type of a milestone and this level of reliability, we’ll just take it…we’re not going to investigate every nut and bolt.'”\u003c/p>\n\u003cfigure id=\"attachment_11241\" class=\"wp-caption alignleft\" style=\"max-width: 640px\">\u003ca href=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/703_KQEDSci_Space_JRoy_GShotwell_19563123.jpg\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"wp-image-11241\" src=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/703_KQEDSci_Space_JRoy_GShotwell_19563123.jpg\" alt=\"Gwynne Shotwell, President and COO of SpaceX, shows off rocket engines being built at the company's headquarters near L.A.

Image by Jayme Roy\u003c/figcaption>\u003c/figure>\n\u003cp>But the private sector isn’t simply providing lower-cost services to NASA. More fundamentally, it is disrupting the space industry by creating new technologies that make getting into space cheaper. And that is expanding the commercial, scientific and even extreme adventure possibilities of space.\u003c/p>\n\u003cp>Many of the country’s new space entrepreneurs hail from the tech sector and some, like Elon Musk, rocketed to prominence with startup success in the early days of e-commerce.\u003c/p>\n\u003cp>“Elon Musk didn’t come from an aerospace background, he is a computer scientist by training,” said Silicon Valley venture capitalist Steve Jurvetson, a SpaceX board member and investor in the company. “And he thinks about the rocket like computer scientists would – modular reuse, modern programming languages, everything.”\u003c/p>\n\u003cp>Clearly, there are risks associated with these new, for-profit space ventures. Not only does the threat of commercial failure loom large, so too is the threat of accidents aboard the rocket ships gearing up to fly wealthy thrill-seekers and space buffs dozens of miles above earth.\u003c/p>\n\u003cp>“If we fly in space often enough, people will die. That’s not a pleasant truth but it is the truth,” said Jeff Greason, CEO of \u003ca href=\"http://www.xcor.com/\">XCOR Aerospace\u003c/a>, a Mojave, California company that, like Virgin Galactic, is also accepting deposits for rides aboard its rocket ship.\u003c/p>\n\u003cp>Tragically, this sentiment became reality on Oct. 31, 2014, when Virgin Galactic’s SpaceShipTwo crashed during a test flight, killing Michael Alsbury, a Scotts Valley native and one of the two pilots on board.\u003c/p>\n\u003cp>The disaster came just three days after the explosion of an unmanned Orbital Sciences rocket in Virginia. The rocket was scheduled to make a resupply mission to the International Space Station, as part of NASA’s Commercial Crew and Cargo program, under which the company, along with its competitor, SpaceX, had won lucrative, billion-dollar contracts to haul cargo to and from the ISS.\u003c/p>\n\u003cp>Hubbard said the disasters occurred in two different areas of the private space sector, so the impact of the crashes should be examined separately.\u003c/p>\n\u003cp>“NASA’s commercial cargo and crew program represents one industry and it has almost nothing to do with the Virgin Galactic crash, which has to do with suborbital space tourism,” Hubbard said. “Orbital Sciences will have to stand down and evaluate their vehicle until they fly again. I don’t see NASA deviating in any substantial way from their commercial cargo and commercial crew program.”\u003c/p>\n\u003cp>Hubbard served as the sole NASA official on the investigation into the February 2003 crash of the Space Shuttle Columbia, which killed all seven crew members.\u003c/p>\n\u003cp>He said he thinks that the crash of SpaceShipTwo will not derail the launch of space tourism, adding that the risks are not unlike those of the early days of aviation.\u003c/p>\n\u003cp>“I think within the next five years, you will see space tourism,” he said. “Flying cross country is safer per seat mille that it is per seat mile driving in your car, but that occurred over a period of 100 years, from Kitty Hawk to now.”\u003c/p>\n\u003cp>“And I think Richard Branson will need to restore the faith of his paying customers that he has a safe operation,” he added. “But I don’t see the interest in suborbital space tourism going away.”\u003c/p>\n\u003cp>As Orbital Sciences and Virgin Galactic struggle to move on from their setbacks, other private space companies have seen major successes in recent months.\u003cs>\u003c/s>\u003c/p>\n\u003cfigure id=\"attachment_11239\" class=\"wp-caption alignleft\" style=\"max-width: 640px\">\u003ca href=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/703_KQEDSci_Space_BMcHugh_Skybox_07343803_2.jpg\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-11239\" src=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/703_KQEDSci_Space_BMcHugh_Skybox_07343803_2.jpg\" alt=\"Technicians at Skybox Imaging work on a satellite in a clean room at the company's headquarters in Mountain View.

Todd Hoeksema directs the observatory, which has been monitoring the Sun’s magnetic field since 1975.\u003c/p>\n\u003cp>(The Wilcox is not, by the way, the source of all the pretty pictures on this page – those come from NASA’s \u003ca href=\"http://sdo.gsfc.nasa.gov/\">Solar Dynamics Observatory\u003c/a>, which is profiled in this \u003ca href=\"http://science.kqed.org/quest/video/journey-into-the-sun/\">KQED Science video\u003c/a> back in 2010.)\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>Hoeksema, reached in his office, told KQED Science that this year’s reversal – “Cycle 24” – is a lot less dramatic than previous cycles, but still exciting enough to have him and others glued to their screens, watching sun spots come and go on the surface of our star.\u003c/p>\n\u003cp>\u003cstrong>So when, exactly, is this flip going to happen?\u003c/strong>\u003c/p>\n\u003cp>\u003cstrong>\u003c/strong>It happening right now. It’s a gradual process, not something that happens over the course of a few hours or even a day.\u003c/p>\n\u003cp>It’s kind of like a tide coming in and out. When does it reach high tide? You can specify a moment after the fact, but as you’re experiencing it, you can’t tell so well.\u003c/p>\n\u003cp>In six months, I’ll be able to tell you pretty closely at which point the sun reversed its polarity, but I can’t do it now.\u003c/p>\n\u003cp>\u003cstrong>What does that mean to say that the polarity reverses?\u003c/strong>\u003c/p>\n\u003cp>\u003cstrong>\u003c/strong>Magnetic fields point one direction or the other. And at the surface of the sun, they point into the surface, or out of the surface. And right now, the polar field in the south is changing from pointing out of the sun, to pointing into the sun. We call that going from positive to negative.\u003c/p>\n\u003cp>It’s\u003cstrong> \u003c/strong>is a big deal because the sun’s magnetic field is what determines how solar wind is organized, and solar wind goes all the way past the planets to the edge of the heliosphere.\u003c/p>\n\u003cp>\u003cstrong>Which is the part of space that’s influenced by the Sun. Didn’t the Voyager 1 spacecraft just \u003ca href=\"http://www.nasa.gov/mission_pages/voyager/voyager20130912.html#.UoGAEeJxXY8\">reach the edge\u003c/a> of the heliosphere?\u003c/strong>\u003c/p>\n\u003cp>There are two Voyager spacecrafts. And people are pretty sure that one of them has recently passed outside the heliosphere for the first time, past Pluto.\u003c/p>\n\u003cp>The problem is that we don’t know what it’s going to look like outside the bounds of the heliosphere. So it’s a little bit hard to say for sure that you’ve done it.\u003c/p>\n\u003cp>http://www.youtube.com/watch?v=K8XwfyNm5XQ\u003c/p>\n\u003cp>\u003cstrong>So the reversal, when it hits, will affect this entire heliosphere. Will we feel it here on Earth?\u003c/strong>\u003c/p>\n\u003cp>Well the Earth has a really good shield, so changes in the solar wind and interplanetary magnetic field don’t affect us on the surface much. What you \u003cem>do\u003c/em> see are changes in the Earth’s geomagnetic field.\u003c/p>\n\u003cp>And that can affect our technological system.\u003c/p>\n\u003cp>At solar maximum you see more solar flares and coronal mass ejections. Those can cause things like power outages. It can interfere with reception of data from satellites. Or even airplanes sometimes have trouble communicating at high latitudes.\u003c/p>\n\u003cp>One of the most spectacular things you can see are auroras, so the northern lights will be more common at northern latitudes. People see those when there’s a lot of activity on the sun.\u003c/p>\n\u003cp>\u003cstrong>And when the solar maximum is happening, we also see a lot more sun spots. \u003c/strong>\u003c/p>\n\u003cp>Yes. A sun spot is a large area on the surface of the Sun where the magnetic field is strong. They’re about the size of the Earth. And they’re dark because they’re a little bit cooler than the rest of the surface.\u003c/p>\n\u003cp>And that’s where the activity happens. When the magnetic field is complicated, you can get these big explosions [solar flares]. The interesting thing is when there are a few sun spots next to each other, that’s when you get the big explosions.\u003c/p>\n\u003cp>\u003cstrong>But it sounds like this particular solar maximum has been a bit of a letdown, right?\u003c/strong>\u003c/p>\n\u003cp>Based on past experience, we’ve probably reached, or are very close to the maximum this cycle, and it hasn’t been a very impressive one. There have been a few large storms – a lot of activity over the last couple weeks, for example — but not many.\u003c/p>\n\u003cp>So there may still be a big storm coming, but we seem to be at the peak, or just passing the peak of this cycle.\u003c/p>\n\u003cfigure id=\"attachment_10860\" class=\"wp-caption alignright\" style=\"max-width: 162px\">\u003ca href=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/20131110_051548_2048_0131_0-162x162.jpg\" rel=\"attachment wp-att-10860\">\u003cimg loading=\"lazy\" decoding=\"async\" src=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/20131110_051548_2048_0131_0-162x162.jpg\" alt=\"NASA's Solar Dynamics Observatory captured this image of a solar flare on Nov. 10, 2013.

It’s a gradual process, not something that happens over the course of a few hours or even a day.\u003c/p>\n\u003cp>It’s kind of like a tide coming in and out. When does it reach high tide? You can specify a moment after the fact, but as you’re experiencing it, you can’t tell so well.\u003c/p>\n\u003cp>In six months, I’ll be able to tell you pretty closely at which point the sun reversed its polarity, but I can’t do it now.\u003c/p>\n\u003cp>\u003cstrong>What does that mean to say that the polarity reverses?\u003c/strong>\u003c/p>\n\u003cp>\u003cstrong>\u003c/strong>Magnetic fields point one direction or the other. And at the surface of the sun, they point into the surface, or out of the surface. And right now, the polar field in the south is changing from pointing out of the sun, to pointing into the sun. We call that going from positive to negative.\u003c/p>\n\u003cp>It’s\u003cstrong> \u003c/strong>is a big deal because the sun’s magnetic field is what determines how solar wind is organized, and solar wind goes all the way past the planets to the edge of the heliosphere.\u003c/p>\n\u003cp>\u003cstrong>Which is the part of space that’s influenced by the Sun. Didn’t the Voyager 1 spacecraft just \u003ca href=\"http://www.nasa.gov/mission_pages/voyager/voyager20130912.html#.UoGAEeJxXY8\">reach the edge\u003c/a> of the heliosphere?\u003c/strong>\u003c/p>\n\u003cp>There are two Voyager spacecrafts. And people are pretty sure that one of them has recently passed outside the heliosphere for the first time, past Pluto.\u003c/p>\n\u003cp>The problem is that we don’t know what it’s going to look like outside the bounds of the heliosphere. So it’s a little bit hard to say for sure that you’ve done it.\u003c/p>\u003c/p>\u003cp>\u003cspan class='utils-parseShortcode-shortcodes-__youtubeShortcode__embedYoutube'>\n \u003cspan class='utils-parseShortcode-shortcodes-__youtubeShortcode__embedYoutubeInside'>\n \u003ciframe\n loading='lazy'\n class='utils-parseShortcode-shortcodes-__youtubeShortcode__youtubePlayer'\n type='text/html'\n src='//www.youtube.com/embed/K8XwfyNm5XQ'\n title='//www.youtube.com/embed/K8XwfyNm5XQ'\n allowfullscreen='true'\n style='border:0;'>\u003c/iframe>\n \u003c/span>\n \u003c/span>\u003c/p>\u003cp>\u003cp>\u003cstrong>So the reversal, when it hits, will affect this entire heliosphere. Will we feel it here on Earth?\u003c/strong>\u003c/p>\n\u003cp>Well the Earth has a really good shield, so changes in the solar wind and interplanetary magnetic field don’t affect us on the surface much. What you \u003cem>do\u003c/em> see are changes in the Earth’s geomagnetic field.\u003c/p>\n\u003cp>And that can affect our technological system.\u003c/p>\n\u003cp>At solar maximum you see more solar flares and coronal mass ejections. Those can cause things like power outages. It can interfere with reception of data from satellites. Or even airplanes sometimes have trouble communicating at high latitudes.\u003c/p>\n\u003cp>One of the most spectacular things you can see are auroras, so the northern lights will be more common at northern latitudes. People see those when there’s a lot of activity on the sun.\u003c/p>\n\u003cp>\u003cstrong>And when the solar maximum is happening, we also see a lot more sun spots. \u003c/strong>\u003c/p>\n\u003cp>Yes. A sun spot is a large area on the surface of the Sun where the magnetic field is strong. They’re about the size of the Earth. And they’re dark because they’re a little bit cooler than the rest of the surface.\u003c/p>\n\u003cp>And that’s where the activity happens. When the magnetic field is complicated, you can get these big explosions [solar flares]. The interesting thing is when there are a few sun spots next to each other, that’s when you get the big explosions.\u003c/p>\n\u003cp>\u003cstrong>But it sounds like this particular solar maximum has been a bit of a letdown, right?\u003c/strong>\u003c/p>\n\u003cp>Based on past experience, we’ve probably reached, or are very close to the maximum this cycle, and it hasn’t been a very impressive one. There have been a few large storms – a lot of activity over the last couple weeks, for example — but not many.\u003c/p>\n\u003cp>So there may still be a big storm coming, but we seem to be at the peak, or just passing the peak of this cycle.\u003c/p>\n\u003cfigure id=\"attachment_10860\" class=\"wp-caption alignright\" style=\"max-width: 162px\">\u003ca href=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/20131110_051548_2048_0131_0-162x162.jpg\" rel=\"attachment wp-att-10860\">\u003cimg loading=\"lazy\" decoding=\"async\" src=\"http://ww2.kqed.org/science/wp-content/uploads/sites/35/2013/11/20131110_051548_2048_0131_0-162x162.jpg\" alt=\"NASA's Solar Dynamics Observatory captured this image of a solar flare on Nov. 10, 2013.
