rest in peace to the heros of the space shuttle Colombia 😢 😭 GOD FUCKING DAMN IT HORSE COCK GRRRRRRRRRRRRRRRRRR I'm so not in the mood mess around get cussed out #nasa #sts107 #adastra #spaceshuttle #Colombia

Hail Columbia! On 2/1/2003, 23 years ago today, mission control lost contact with Space Shuttle Columbia as it broke apart in flames about 203,000 feet over Texas. This was 16 minutes before it was supposed to touch down in Florida.

Remember the pioneers!

A tank part broke during launch, damaging heat-shielding on the left wing of #SpaceShuttle #Columbia. Lacking an ability to rescue the crew or repair the damage, #NASA allowed reëntry, leading to a catastrophic break-up on #ThisDayInHistory in 2003, killing all seven of its crew.

#OnThisDay #SpaceShuttle #Columbia disintegrated during reentry into the Earth's atmosphere (2003) resulting in the deaths of all seven crew members.

RE: https://social.heise.de/@heiseonlineenglish/115976990911921549

The final undoing for the crew was that #NASA had dispensed with an escape system in the design of the #SpaceShuttle -- for cost reasons. The cockpit was found largely intact. A parachute might have saved the lives of the seven deceased

".. O-rings .. these rings were never intended to be used to cover expanding gaps, .. "

".. felt frustrated by the slow pace + “time-consuming” public meetings + briefings “of so little use.” He did his own research .. even created his own report .. released publicly. .."

I get a “This Day in History” email from https://history.com every day. Today’s one reminded me that 40 years ago, the Challenger space shuttle accident happened https://www.https://history.com/this-day-in-history/january-28/challenger-explodes . I was a junior in high school and remember hearing about it over the loudspeaker. So many people were really sad that day. It feels like yesterday, but also a long time ago. #Challenger #SpaceShuttle #ThisDayInHistory

I bought "Remove Before Flight" tags on eBay in 2010—it turns out they're from Challenger https://arstechni.ca/tCSb #MichoudAssemblyFacility #RemoveBeforeFlight #Spaceexploration #spacememorabilia #40thanniversary #LockheedMartin #spaceartifacts #externaltank #spacehistory #Spaceshuttle #Challenger #disaster #40years #STS-51L #tragedy #Space #ET-26 #eBay #NASA #Tag

I watched with classmates on #ThisDayInHistory in 1986 as the #SpaceShuttle #Challenger exploded on live television. The principal thought watching would be great for us as teacher #ChristaMcAuliffe was on board. I still lament the fall in public #SpaceExploration funds/efforts.

Jan. 28, 1986. 40 years ago today: Space Shuttle Challenger Disaster https://prophetmadman.blogspot.com/2026/01/40-years-ago-today-space-shuttle.html

Forty years ago today, I was a senior in high school sitting in my yearbook class when our teacher rolled a TV into our classroom and said, "the space shuttle just blew up." We all thought she was joking. It was obviously no joke.

Challenger: The disaster five people saw coming

Forty years ago, the Challenger space shuttle disintegrated just after lift-off, killing its crew and changing the history of spaceflight. A small team of engineers tried to prevent the tragedy — but they were overruled.
