The day earlier than the Challenger launch catastrophe, senior NASA official James Beggs made an pressing telephone name to the company’s chief engineer.
Beggs was on non permanent go away from his NASA administrator place on Jan. 27, 1986 on account of a short authorized matter unrelated to his company work. Whereas watching pre-launch tv protection of Challenger, Beggs (and lots of others) noticed icicles on the launch tower. However neither Beggs nor engineer Milt Silveira may come up with the launch resolution workforce to cease the countdown.
“He is calling the Cape, begging them to cease the rely,” 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 isn’t the administrator. There was [instead] an appearing administrator.” (That individual 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 folks on board, partially on account of a mechanical failure induced by the chilly.Â
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 folks of all nations who’ve misplaced their lives throughout a spaceflight, or in coaching or testing to get there.Â
Greater than 20 names are inscribed (opens in new tab) on a Space Mirror Memorial (opens in new tab) at NASA’s Kennedy Area Heart Customer Heart Complicated close to Orlando, Florida, which incorporates most astronauts who died whereas serving at space companies or throughout non-public spaceflights. The latest title, Virgin Galactic SpaceShipTwo co-pilot Michael Alsbury (opens in new tab), was added in 2020 (opens in new tab).Â
NASA’s Day of Remembrance takes place annually shut to a few 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 realized are particularly entrance in thoughts, company officers emphasised, as NASA flies new human-rated automobiles which can be 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 folks 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 packages like Mercury or Gemini.
To make certain, older packages will also be susceptible to issues of safety, however younger spacecraft are topic to bigger unknowns merely on account of an absence of flight information. NASA plans to incorporate further security briefings this yr on prime of its month-to-month security panel discussions as one step to holding engineers knowledgeable, company officers mentioned.
“Everyone knows after we’re making an attempt one thing new, we’re by no means going to be 100% protected as a result of there are issues that we will not predict which may occur,” NASA deputy administrator Pam Melroy, a former shuttle astronaut, advised 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 Area Heart in useless for STS-107’s return.
“I knew that it was preventable. I knew we may have carried out one thing,” Cabana mentioned of the deadly breakup that killed seven astronauts 20 years in the past this yr. “It’s extremely exhausting. I used to be the one which needed to inform the households they weren’t coming house. I do not ever wish to have to try this once more.”
