The crew didn’t blow up(src).
The flight, and the astronauts’ lives, did not end at that point, 73 seconds after launch. After Challenger was torn apart, the pieces continued upward from their own momentum, reaching a peak altitude of 65,000 feet before arching back down into the water. The cabin hit the surface 2 minutes and 45 seconds after breakup, and all investigations indicate the crew was still alive until then.
We were led out of our classrooms to watch it since we lived in FL. When the launch went pear-shaped, nobody really understood what had happened, we just thought it was part of the fuel tanks dropping away. We went back in, sat down and continued our day. I don’t think the teachers ever told us something went wrong and I found out about it that night at home.
Many humane societies welcome fostering and it allows you not just a chance to answer all these questions but also a chance to see how well you fit with a specific cat.
Don’t allow yourself to get peer-pressured into multiple pets at the start. Every cat is different and some sleep so much and are so low energy that they won’t notice your absence while others will miss you right away. Fostering will help you sort this out as well.
I think everyone’s life could be made better with a cat in it. The fact that you’re aware and concerned with a future pet’s wellbeing in your care makes me think you’re going to be a great caretaker.
