ORLANDO, Fla. — “Never again” is the phrase echoed among NASA leaders recalling the last major tragedy in the space program that occurred 20 years ago this week, when Space Shuttle Columbia broke apart over Texas on Feb. 1, 2003, never making its way back home to Florida.
But with more spacecraft, more players and farther-flung destinations like the moon and Mars, the potential for another disaster has grown.
NASA Administrator Bill Nelson, who as a member of Congress flew on the space shuttle on the mission immediately before the Space Shuttle Challenger disaster in 1986, recalled this week how engineers at one of the shuttle’s contractors told their managers to call off the launch because of the weather. The cold was ultimately blamed for shrinking an O-ring that led to the explosion.
