This image provided by NASA/JPL-Caltech shows a simulation of asteroid 2012 DA14 approaching from the south as it passes through the Earth-moon system on Feb. 15, 2013. The 150-foot object will pass within 17,000 miles of the Earth. NASA scientists insist there is absolutely no chance of a collision as it passes. (AP Photo/NASA/JPL-Caltech)

FILE - In this Aug. 6, 2007, file photo, Space shuttle program manager Wayne Hale listens to a question from members of the media during a launch readiness news conference for the Space Shuttle Endeavour at Kennedy Space Center. Hale wrestled with what he thought was a hypothetical question: What do you tell the astronauts of a doomed space shuttle Columbia? When the NASA official raised the question in 2003 just days before the accident that claimed seven astronauts' lives, managers thought _ wrongly _ that Columbia's heat shield was fine. They told astronauts they weren't worried about launch damage. But after a managers meeting, mission operations chief Jon Harpold told flight director Hale that if something was wrong it was hopeless and maybe they shouldn't tell the crew. Hale wrote about the conversation ten years later, saying NASA would have tried to save the crew had it realized the problem's true severity. He said the lesson from Columbia is: Don't give up.

In the RLV Hangar, the floor grid is marked with a growing number of pieces of Columbia debris in this NASA handout photo dated March 13, 2003. The Columbia Reconstruction Project Team will attempt to reconstruct the orbiter as part of the investigation into the accident that caused the destruction of Columbia and loss of its crew as it returned to Earth on mission STS-107. February 1, 2013 marks the 10th anniversary since the orbiter broke apart in the skies over Texas, killing the crew of seven astronauts. Columbia broke up as it re-entered the atmosphere because of damage to the leading edge of the left wing. REUTERS/NASA/Handout

FILE - In this Jan. 2003 file photo, astronaut Rick D. Husband, mission commander of the space shuttle Columbia, is pictured on the aft flight deck. Husband and six crew members were lost when Columbia broke up during re-entry over north Texas on Feb. 1, 2003, . This picture was on a roll of unprocessed film recovered by searchers from the debris later, released by NASA on June 24, 2003. Ten years later, reminders of Columbia are everywhere, including up in the sky. Everything from asteroids, lunar craters and Martian hills, to schools, parks, streets and even an airport (Rick Husband Amarillo International Airport) bear the Columbia astronauts' names. Two years ago, a museum opened in Hemphill, Texas, where much of the Columbia wreckage rained down, dedicated to "remembering Columbia." About 84,000 pounds of that wreckage, representing 40 percent of NASA's oldest space shuttle, are stored at Kennedy and loaned for engineering research. (AP Photo/NASA)

FILE - This photo provided by NASA in June 2003 shows STS-107 crew members,from the left (bottom row), wearing red shirts to signify their shift’s color, are astronauts Kalpana Chawla, mission specialist; Rick D. Husband, mission commander; Laurel B. Clark, mission specialist; and Ilan Ramon, payload specialist. From the left (top row), wearing blue shirts, are astronauts David M. Brown, mission specialist; William C. McCool, pilot; and Michael P. Anderson, payload commander. The astronauts were killed on Feb. 1, 2003, in the final minutes of their 16-day scientific research mission aboard Columbia. Altogether, 12 children lost a parent aboard Columbia. The youngest is now 15, the oldest 32. (AP Photo/NASA, File)
