Since I live in the US, it's been impossible not to follow this as it's on the news day and night. It's just absolutely horrible, it brings back the awful memories of when Challenger exploded in 1986.
Honestly, I feel a little numb about it right now. It seems like every single day we are bombarded by hideous happenings that have taken more lives. I don't know the facts of what the astronauts went through (even NASA may never know) but it is so overwhelmingly sad to think that they had any idea they were going to die. Many of them had families and children...I can't even fathom knowing for a second I would never see my dd again or that she would grow up without me.
One thing that is concerning is what will now be done about the astronauts still aboard the space station. They have one escape vessel, that could bring them back to earth, but has not been tested with a live crew. NASA has suspended all of their shuttles from leaving earth during the investigation and any repairs or adjustments to be made. After the Challenger tragedy, it was THREE YEARS before NASA cleared another shuttle for launch. Granted, Challenger had a design flaw and apparently Columbia had a repair problem so it shouldn't be so long this time. But still, I can't imagine being trapped in space. They can still get minimal supplies from remote shuttles being launched from Russia but they are not worthy for human travel.
Another thing that has sickened me is that some of the people living in the debris field have collected pieces of the shuttle (including a helmet), despite being warned that it is likely radioactive. They took the Columbia debris and put it up for auction on Ebay! How disrespectful can people be? It's like stomping on their grave and selling the headstone. Ebay promptly put a stop to the auctions, but the fact that anyone actually did it in the first place places a giant dent in my faith in humankind. I know, all the crap everyone is pulling lately wasn't enough or something.
It's all just so very sad
