NASA announced plans to name the landing site of the Mars Opportunity rover in honor of the Space Shuttle Challenger’s final crew. The area in the vast flatland called Meridiani Planum, where Opportunity landed this weekend, will be called the Challenger Memorial Station. The seven-member crew of Space Shuttle Challenger was lost when the orbiter suffered an in-flight breakup during launch Jan. 28, 1986, 18 years ago today.
