The day earlier than the Challenger launch catastrophe, senior NASA official James Beggs made an pressing telephone name to the company’s chief engineer.
“He is calling the Cape, begging them to cease the depend,” present NASA administrator Invoice Nelson mentioned of Beggs throughout a televised NASA city corridor at this time (Jan. 24). “And so they will not take his name, as a result of he is not the administrator. There was [instead] an appearing administrator.” (That particular person was William Graham.)
Beggs, who died in 2020 at age 94, solely mentioned in his 2002 NASA oral history (opens in new tab) that the launching workforce was “sequestered” and unresponsive to calls when recalling that incident. Regardless, the launch resolution was catastrophic: After spending in a single day in freezing temperatures, the shuttle Challenger exploded the next morning with seven individuals on board, partly resulting from a mechanical failure induced by the chilly.
Nelson, who accomplished space shuttle mission STS-61-C on Columbia simply 10 days earlier than Challenger’s launch, mentioned he “collapsed to his knees” when he heard in regards to the explosion and the lack of the newly launched crew.

NASA commemorated Challenger and all those that died within the pursuit of spaceflight within the city corridor, held two days earlier than the company’s annual Day of Remembrance that discusses spaceflight safety and commemorates individuals of all nations who’ve misplaced their lives throughout a spaceflight, or in coaching or testing to get there.
Greater than 20 names are inscribed (opens in new tab) on a Space Mirror Memorial (opens in new tab) at NASA’s Kennedy House Heart Customer Heart Advanced close to Orlando, Florida, which incorporates most astronauts who died whereas serving at space companies or throughout personal spaceflights. The newest identify, Virgin Galactic SpaceShipTwo co-pilot Michael Alsbury (opens in new tab) , was added in 2020 (opens in new tab) .
NASA’s Day of Remembrance takes place annually shut to 3 vital failures in spaceflight: Challenger’s loss on Jan. 28, 1986; a deadly hearth that claimed three Apollo 1 crew members on Jan. 27, 1967; and the breakup of shuttle Columbia with seven crew members on board on Feb. 1, 2003. This yr will mark the twentieth anniversary of mission STS-107 aboard Columbia, together with the thirty seventh anniversary of mission STS-51L on Challenger and the 56th anniversary of Apollo 1’s launch pad hearth.
Every of those incidents arose from a posh intersection of human and technical error, and NASA officers acknowledged within the city corridor that the Day of Remembrance stays not solely delicate, however related. Classes discovered are particularly entrance in thoughts, company officers emphasised, as NASA flies new human-rated automobiles which are comparatively untested in spaceflight.

Orion made it across the moon final yr and again once more throughout Artemis 1 , however solely with mannequins within the crew seats. Boeing’s Starliner docked with the International Space Station in 2022 as effectively, however with no astronauts but on board.
In the meantime, SpaceX ‘s Crew Dragon has flown eight instances with individuals on board: Twice for personal ventures and half a dozen instances for NASA. These are nonetheless comparatively low numbers in comparison with the space shuttle or Russia’s Soyuz spacecraft, which have exceeded 130 flights every, however Dragon’s flight price is akin to older NASA applications like Mercury or Gemini .
To make sure, older applications may also be susceptible to questions of safety, however younger spacecraft are topic to bigger unknowns merely resulting from an absence of flight information. NASA plans to incorporate extra security briefings this yr on high of its month-to-month security panel discussions as one step to maintaining engineers knowledgeable, company officers mentioned.

“Everyone knows once we’re attempting one thing new, we’re by no means going to be 100% secure as a result of there are issues that we won’t predict that may occur,” NASA deputy administrator Pam Melroy, a former shuttle astronaut, instructed attendees on the city corridor. “However every of us ought to do not forget that it may occur to us.”
Nelson, Melroy and affiliate administrator Bob Cabana, who’ve all flown within the space shuttle, repeatedly emphasised that accountability for spaceflight security lies with everybody, together with administration. Cabana recalled personally briefing the households of the Columbia astronauts about their deaths, after standing on the touchdown runway at NASA’s Kennedy House Heart in useless for STS-107’s return.
“I knew that it was preventable. I knew we may have accomplished one thing,” Cabana mentioned of the deadly breakup that killed seven astronauts 20 years in the past this yr. “It’s extremely onerous. I used to be the one which needed to inform the households they weren’t coming house. I do not ever need to have to do this once more.”
