The work that NASA astronauts are doing right now on the Hubble Telescope is truly humbling. They've been working and training for years for these few days of work. Think about that!

And when they all get home and new/better images start coming in from Hubble, how cool will it be for them to be able to say until their last breath that they helped bring Hubble fully back to life!

I'm gonna go eat some humble pie.
