- Late January and early February are the anniversaries of two of the most disastrous events in the history of spaceflight. What did we learn from these events, and how do we move forward?

Pretty dark and scary to think that every astronaut about to launch to space must have considered that it may very well be a one way trip.
Man, I watched the Challenger disaster a month before I turned three live on television. Growing up with those images, I went from wanting to be an astronaut to wanting to become an engineer to help make spaceflight safer for the future.
I'm not american, but whenever i see the american space program, i wish i was. Well, i guess i'll have to be proud of the human race, instead, LOL. Shuttles were expensive, dangerous, inneficient, and old, but... damn, they where cool. The current trend of capsules seems like a step backwars, altought, really, it isn't. If only they had given VentureStar a chance...
Neither Challenger nor Columbia exploded, they were both ripped apart by aerodynamic forces.
Columbia didn't explode. Like Challenger is broke up due to aerodynamic forces.
You said it at the start, space flight is dangerous. It's obviously imperative that we try to make that danger as small as possible, but it's always going to be there. To me it says something big about the human race that we decide to face these ever-present dangers in the spirit of science and exploration.
Shout-out to one scientist who dedicated a lot of his life to proving that the O-rings were the fault on the Challenger and that the NASA top bosses were to blame for the accident. I'm guessing you've heard of him, but not what he did in the wake of the Challenger disaster... his name was Richard Feynman.
Worth mentioning Gus Grissom, Ed White, and Roger Chaffee, who died testing Apollo 1 before launch.
Both of these serve as a warning of what happens when even seemingly small problems are ignored, and what happens when humans become complacent.
It's nice that a former enemy of the US is kind enough to give them a lift.
simple, ALWAYS LISTEN TO THE FUCKING ENGINEERS!
When I was a kid, I had several surgeries and was sick a lot. I also loved everything space-related. When I told my mother I was feeling sick and didn't want to go to school, I wasn't lying; I did feel sick, though I had gone to school feeling sicker, and I didn't want to go to school, though it was because I wanted to watch the Challenger launch, not because I was sick.
as the dedication at the beginning of Star Trek the voyage home ( the one with the whales) says "The cast and crew of Star Trek wish to dedicate this film to the men and women of the spaceship Challenger whose courageous spirit shall live to the 23rd century and beyond..."
Anyone else tear up a little? Just me?
The meta-lesson: When physics matters, politics and bureaucracy KILLS!
I was 15 (and I live in Texas, btw). I was a big fan of the Columbia (back in 4th grade we were assigned groups named after the space shuttles and I was in Columbia) and I'd heard it was coming back that day and we might be able to see it in the sky on its way back.
- Challenger, go with throttle up.
These extraordinary human beings are and always will be true heroes.
An interesting thing I found out this year was that my dad was actually part of the group tracking the debris coming down, since he was part of the USAF weather squadron stationed at Barksdale AFB right outside of Shreveport Louisiana. (Otherwise known as right smack in the middle of the cloud in the National Weather Service picture...which might well be from his squadron's radar picture)
I have mixed feelings about the Shuttle program, I grew up thinking they were the coolest things ever, I played with my model Endevour until it had all but fallen apart, and spent countless hours reading space books and reading the shuttle's Wikipedia pages. I was devastated when the fleet was retired without a viable replacement, and was even more mad when the Ares program was cancelled. But then I started looking a bit further, as it turns out, the shuttles were incredibly expensive, costing about a billion per launch when you average out the price of the entire program, costing more than if we had just stuck with the Saturn program, a fleet of rocket that only ever had one partial failure when an engine failed on one of the Apollo missions and still managed to make it to space on its 4 remaining F-1 engines. Then there were the two failures, a 3/5 survival rate for the shuttle fleet isn't exactly stellar.
