It's clear that the only thing that is inhibiting us from doing further human exploration of space is money and the will to do it.
I would say the biggest challenge I had as a woman in science is be a mom. It's really hard. It's very hard work having children, and I tell kids this all the time.
Having high quality daycare is by far the most important thing you can do when your kids are little. When I relocated, I spent more time looking for daycare than I did looking for a house.
Hubble wasn't designed to look at objects in our solar system, but after it was launched, astronomers realized that with just a little bit of modification to the software, it could look at solar system objects.
I feel like an old-fashioned mountain climber when I am making discoveries, seeing something for the first time, realizing that no human before me has ever seen what I am seeing. It takes your breath away - for just a moment, you feel a pause in time, as you know you are crossing a boundary into a new realm of knowledge.
Because Hubble's been up so many years now, it's actually given us a window to things like... how planets' atmospheres actually change, evolve... over time.
We live inside the atmosphere of an active star.
There are amateurs who have seen that one of Uranus' poles is brighter than the other, or who have seen cloud formations on the planet. For all we know, interesting things are happening there all the time.
I have a little piece of Hubble that someone brought back from one of the repair missions. It's on my desk, where I work. I do feel a personal connection to it. It's been part of my life for 20 years.
