Lessons from shuttle Columbia disaster could stave off next tragedy

“By no means once more” is the phrase echoed amongst NASA leaders recalling the final main tragedy within the space program that occurred 20 years in the past this week, when House Shuttle Columbia broke aside over Texas on Feb. 1, 2003, by no means making its approach again dwelling to Florida.

However with extra spacecraft, extra gamers and farther-flung locations just like the moon and Mars, the potential for one more catastrophe has grown.

NASA Administrator Invoice Nelson, who as a member of Congress flew on the space shuttle on the mission instantly earlier than the House Shuttle Challenger catastrophe in 1986, recalled this week how engineers at one of many shuttle’s contractors advised their managers to name off the launch due to the climate. The chilly was in the end blamed for shrinking an O-ring that led to the explosion.

“The administration wouldn’t hearken to the engineers begging them to cease the rely, and that went up all the best way to the highest,” Nelson mentioned.

The warning indicators for Columbia on STS-107 have been on the market as effectively. Nelson’s mission’s shuttle commander, Robert “Hoot” Gibson, advised Nelson how he would at all times examine the orbiter in space throughout missions he flew within the time between the 2 shuttle disasters.

“You’d have a look at the underside or the perimeters of the orbiter with these delicate silicone tiles, and he mentioned it was like any individual had taken a shotgun and simply shredded it,” Nelson mentioned. “A warning about what was to return.”

The 2 shuttle accidents, notably, led to adjustments in how NASA operates, with a safety-first mentality that may appear to decelerate progress at occasions, Nelson mentioned.

“The underside line is that this. Converse up. A query, even a easy query is extra forgivable than a mistake that may end up in a tragedy, and every of us has a accountability to domesticate a work environment the place each member of the NASA household feels empowered to voice doubt. Make your issues heard. Talk overtly,” he mentioned.

The occasions between NASA’s three main tragedies have been near 20 years every, and now NASA has gone the longest run with out human lack of life in spaceflight.

Throughout these runs, although, the American space program featured just one spacecraft managed by the U.S. authorities. Now NASA has a number of industrial companions with SpaceX’s Crew Dragon and Boeing’s CST-100 Starliner flying astronauts to the Worldwide House Station whereas additionally working with its personal Orion crew capsule for moon missions within the Artemis program.

Later this decade, NASA will depend on SpaceX’s Starship in addition to probably a second industrial lunar lander to maintain its astronauts protected throughout journeys to the moon’s south pole, a part of NASA’s plans to finally ship people to Mars.

Alex Roland, a retired Duke College historical past professor and former NASA historian, warns the push to deep-space exploration may grow to be lethal.

“Do not ship individuals to Mars or the moon—but,” he mentioned, noting human missions are “pointless, inefficient and exorbitantly costly. … The spacecraft methods redundancies vital to ensure human survival of a Mars mission can solely be imagined. Sending individuals to Mars in any foreseeable future is a harmful, costly stunt. Go away it to Elon Musk.”

Even for SpaceX, although, he foresees potential catastrophe.

“I believe (Musk) has an uncanny potential to attain very troublesome objectives,” Roland mentioned. “For my part, he’s transferring quicker than NASA ever has. I can be shocked if SpaceX doesn’t expertise a fatal accident earlier than it makes an attempt a Mars mission. I discover it onerous to foretell how that can change the calculus.”

He added, “Musk may change his agenda. The federal government may improve regulation of non-governmental spaceflight. NASA’s deadly accidents didn’t change NASA’s manned packages, however they certain set them again for some time.”

Industrial efforts nearer to dwelling have confirmed dangerous as effectively.

Blue Origin and Virgin Galactic proceed to pursue space tourism flights for brief suborbital journeys, an endeavor that has seen the Federal Aviation Administration already halt flights for security issues for each firms. Blue Origin’s New Shepard stays grounded after a booster incident final 12 months despatched its capsule blasting away to security, though that flight didn’t have people on board.

Down the road, Sierra House appears to develop its Dream Chaser cargo spacecraft, which may fly for the primary time this 12 months, into one that would fly people as effectively.

The sector is rising, with projections of the variety of individuals having flown to space—greater than 600 in 60 years because the first individual in space in 1961—to greater than double within the subsequent decade.

“It is a problem, however it’s the accountability of us because the overseers regardless that we might have a companion within the public-private sector,” Nelson mentioned. “We have got to look over their shoulder.”

Deputy Administrator Pam Melroy mentioned she expects human industrial spaceflight will flourish the identical approach industrial aviation did.

“Sooner or later, the trade must study its classes by itself,” she mentioned noting NASA’s shut relationship with the FAA to scrutinize industrial spaceflight. “We hope to switch that information as issues go ahead, however I believe for not less than a decade or extra to return, we’ll be extraordinarily engaged. … They’ll should develop up and have their very own regulator sometime, and we’ll help that as finest we are able to with all of the information of the company.”

One a part of that effort is NASA’s Apollo Challenger Columbia Classes Realized Program primarily based out of KSC. This system is managed by Michael Ciannilli, who was a part of the Columbia restoration group and liable for the transferring Challenger and Columbia exhibit “Ceaselessly Remembered” at KSC Customer Advanced that opened in 2015.

Which means venturing out and speaking with not solely teams inside NASA, however industrial aerospace companions, and even industries outdoors of aviation that would reap some profit within the wake of tragedy. This system tackles all the things from engineering to management-type discussions.

The primary thrust of this system is to stop future accidents.

“We’re sharing these methods with of us which are on design groups, designing the brand new methods, these enormous new rockets—sharing new processes, engaged on establishing cultures,” he mentioned. “We’re additionally working with all the industrial spaceflight suppliers which are approaching board, and so they’re growing their methods and their rockets and procedures and packages. We’re working with them intimately now, so it is nonetheless approach earlier than their first flight.”

That features discussions with SpaceX, Blue Origin, Boeing and others.

Ciannilli mentioned thinks the Columbia and Challenger disasters assist him convey dwelling that message of security.

“They’re simply flying a brand new mission,” he mentioned of the 2 space shuttles. “The mission is to encourage, educate and alter issues and to positively impression the long run for the higher.”
