The CNN Unique Sequence “Space Shuttle Columbia: The Final Flight” uncovers the occasions that finally led to catastrophe. The four-part documentary concludes at 9 p.m. ET/PT Sunday.

Maybe greater than some other second in NASA’s historical past, the Columbia shuttle disaster reshaped the US area company’s strategy to innovation, endlessly altering the way it balanced threat with the decision to discover past Earth.
The tragedy killed seven astronauts because the Columbia shuttle disintegrated upon its return to Earth on February 1, 2003, attributable to injury the car sustained throughout launch. Greater than 20 years later, the teachings discovered proceed to form the area business and NASA’s strategy to working with private-sector companions reminiscent of SpaceX.
Adjustments at NASA had been vital, in accordance with a proper investigation concerning the Columbia catastrophe printed six months after the accident. A tradition of complacency and misplaced belief within the area shuttle’s experimental design spelled catastrophe, the report outlined.
Considerations about car security from employees engineers had been additionally left unheeded by administration, in accordance with earlier reporting and a brand new CNN docuseries, “Space Shuttle Columbia: The Final Flight.”
The catastrophe led on to the choice to finish the broader NASA area shuttle program, forcing the US area company to depend on Russia for rides to area — one among myriad methods Columbia altered historical past.
Cultural modifications: ‘Security days,’ evaluate boards and spherical tables
Columbia marked the second lethal mishap for the shuttle program after the area shuttle Challenger exploded throughout launch in January 1986.
Following the Columbia catastrophe, NASA grounded its remaining fleet of three shuttles because the area company sought to parse what went fallacious.
“We spent the following year-plus … making an attempt to encourage the (NASA) tradition to place security first and, most significantly, to make sure that those who had dissenting opinions or questions had been heard,” Wayne Hale, then deputy supervisor of the area shuttle program, advised CNN. “It was all within the title of making an attempt to encourage individuals to talk up.”
Some modifications had been easy: An audio-conferencing system was changed with video, Hale mentioned. And within the shuttle mission’s administration workforce assembly room, a spherical desk changed the oblong desk.
“We had been advised by the sociologist that for those who had this straight, lengthy desk with the daddy determine on the head … which may discourage individuals from talking up,” Hale mentioned.
NASA additionally had “security days” — time put aside for engineers to cease work and simply “ponder the right way to higher enhance our group’s strategy to security,” Hale added.
The tragedy touched the whole NASA group, leaving a legacy with which the remaining astronaut corps needed to contend.
“Clearly it affected us emotionally,” mentioned Garrett Reisman, a spacecraft engineer from California who in 2003 was member of the NASA astronaut corps ready to make his first foray into area.
“I keep in mind being referred to as into the workplace, volunteering to work with households,” Reisman added.
For 2 years, he mentioned his complete job at NASA was to verify in on the household of Ilan Ramon, the Israeli astronaut who had died on the Columbia mission. He went with Ramon’s youngsters to their steerage counselor to assist them select lessons. He and different astronauts helped discover a home for Ramon’s spouse. Reisman nonetheless visits the household in Israel every year.
“It helped me perceive precisely what the implications are, not only for you (the astronaut) — however for all of the individuals you like,” Reisman mentioned. “That stayed with me.”
Reisman flew on two shuttle missions after this system resumed flight in 2005 as NASA put in quite a few security stopgaps, together with a mandate {that a} spare shuttle was all the time ready to rescue crew members in orbit if their car was broken throughout launch.
Regardless of any lingering anxieties, the modifications offered a newfound sense of safety, Reisman mentioned.
“We had all these inspection and restore methods,” he mentioned. “I felt like after I was flying on Endeavour and Atlantis and Discovery (the three remaining shuttles) that it was rather more protected than what the crew on Columbia — and positively Challenger — had taken on.”
The area shuttle Atlantis accomplished the ultimate flight of this system in July 2011, leaving NASA with out a means to fly its astronauts to the Worldwide House Station.
This system’s finish compelled the area company to show to Russia, which — as tensions eased within the post-Chilly Battle period — was a main US accomplice on the area station and had a dependable car referred to as Soyuz to ferry its cosmonauts to the orbiting outpost.
The association stored NASA astronauts space-bound. However as US-Russia relations grew to become strained as soon as once more within the mid-2010s, sharing these rides to area grew to become more and more politically unpopular.
By the tip of the shuttle program, a contingent of engineers inside NASA already had concepts for the trail forward.
Relatively than retaining the design and growth of the following astronaut-worthy spacecraft in-house, NASA may flip to the burgeoning personal area business to take over the duty.
Industrial firms had a bit extra leeway to innovate within the post-Columbia period, Hale and Reisman acknowledged.
“I feel one of many huge challenges was to seek out the proper path between the actually big paperwork and paperwork necessities that NASA had — which in some instances had been frankly excessive — and work out the right way to accommodate the tradition of a business (firm),” Hale mentioned.
In 2014, NASA chosen the Elon Musk-led SpaceX and its longtime accomplice Boeing to take up the duty.
The prospect of shifting quicker and paving a brand new future for the astronaut corps excited Reisman, who left NASA in 2011 to work for SpaceX on its Crew Dragon car.
Cautious after the Columbia tragedy, NASA didn’t all the time see eye to eye with its business companions. The end result was a culture clash that performed out behind the scenes.
“I’ve an org chart that exhibits all of the completely different (NASA) evaluate boards that every one engineers engaged on NASA packages needed to go to approve any main design determination,” Reisman mentioned. “What occurred was, post-Columbia, they had been listening to dissenting voices so strongly that every one of these dissenting voices successfully grew to become a veto.”
Lengthy, painful conferences characterised relations between SpaceX and NASA, in accordance with records of the period that the area company compiled.
However finally, SpaceX received its Crew Dragon to the launchpad, and its inaugural crewed mission in 2020 returned astronaut launches to US soil for the primary time in a decade.
Boeing remains to be working towards the primary crewed mission of its Starliner spacecraft.
The teachings discovered from Columbia — and the Challenger explosion earlier than it — have left an indelible mark on the design of recent US spacecraft.
“In all probability the most important instance is simply by placing the crew on prime of the rocket as an alternative of on the facet of the rocket, you get rid of the hazard of any particles coming off the car and hitting the spacecraft,” Reisman mentioned.
“Plenty of these issues had been baked into the necessities that NASA gave us,” he mentioned, referring to directions given to SpaceX and Boeing.
Crew Dragon, Starliner and NASA’s personal Orion capsule — designed to return people to the moon later this decade — all launch atop rockets relatively than being strapped to the facet of them.
On this new period of rocketry with business firms largely main the way in which, Hale mentioned the problem is to make sure the area business avoids being lulled into the identical complacency that led to the Columbia catastrophe.
“My solely concern now, as an outdated retiree, is — all these years later — how effectively are these classes nonetheless communicated?” Hale mentioned. “After 20 years, are individuals beginning to overlook?”
“Vigilance,” he added, “has received to be maintained.”
