This has been a month of dashed hopes for astronomers around the world. Last month it seemed possible that an asteroid the size of a Boeing 737 jet was due to collide with Mars on January 30. Today that seems far less likely, but, as Amy Standen reports, astronomers consider it a wake up call.
You may listen to the “An Asteroid’s Close Call” radio report online, as well as find additional links and resources.
