NASA learning from mistakes

So it seems NASA is finally learning from the past. NASA is launching the Atlantis to preform technical upkeep to the Huble Telescope. They've also created a backup spaceship just incase something goes wrong called the Endeavour. If something is to go wrong on the Atlantis NASA will launch a rescue ship that will connect to the bottom of the ship and over two days the astronauts will space walk using a tension rope onto the Endavour. This is what seems like a great idea. The upkeeping of the hubble is necessary. This telescope has traveled space about 3 billion miles. The astronauts will preform 5 space walks in 5 days which is very dangerous and for them to know someone has got their back has got to put them and their families at ease. If something is to go wrong then the astronauts will safely transfer and travel home. This leaves the Atlantis to burn up when reentering the atmosphere over the ocean while the Endeavour brings everyone home safely. Hubble has done so much since it was launched in 1990 and these brave men and women are so passionate about their work and the wellness and growth to human society its amazing.
