The scientific consensus is that climate change is real, urgent, and caused by humans. This science should be both supported and understood by anyone who hopes to lead NASA, one of our nation's top science agencies.
A lot of missions for NASA or experiments on accelerators happen through a whole process of scientific retreats, long-range planning, forming collaborations to do studies - all this kind of stuff. It's very democratic.
NASA is an utterly fascinating place, and the fact that the buildings look so anonymous almost makes it more fascinating. You walk by a generic office-park-looking building, and you have no idea what's going on inside.
NASA, and all the other spacefaring nations of the world, have agreed to a set of 'planetary-protection' principles, aimed at preventing the accidental contamination of another habitable world with organisms from Earth.
I like to think of 'the studio' as a laboratory where I can go in, learn tricks, apply, revise, and release. I'd figure I had about the same emotional attachment to my craft as a guy over at NASA does over... NASA stuff.
How fantastic that the American ingenuity of NASA scientists got us to Mars. It makes me proud to be an American. I can't get enough of these images from when the probe touched down. These scientists are American heroes.
NASA's Office of Commercial Exploration has been concerned about protecting the landing zones where humans first walked on the Moon, and one of my colleagues, ecologist Margaret Race, has been part of their deliberations.
I am humbled and excited by new opportunities for me to support and share the amazing work NASA is doing to help us travel farther into the solar system and work with the next generation of science and technology leaders.
Data from orbiting telescopes like NASA's Kepler Mission hint that the tally of habitable planets in our galaxy is many billion. If E.T.'s not out there, then Earth is more than merely special - it's some sort of miracle.
Me personally - not something to do with NASA - I do think there is a God, and it's somebody looking out for us and trying to guide us to live a very happy, productive life. There is further meaning. That's just my thought.
Personally, I've got bigger hopes for NASA. I will stipulate it should keep putting telescopes in space so we can figure out where we fit in the universe, and it should also keep building those little robots that can and do.
When I was a kid, I was a bit of a space geek. I loved the space program and all things NASA. I would read books about our solar system; I had pictures of the Space Shuttle on my bedroom wall. And yes, I even went to Space Camp.
I had as much time to prepare for that moon landing as NASA did, and I still was speechless when it happened. It just was so awe-inspiring to actually be able to see the thing through the television that was a miracle in itself.
Sequencing DNA on the ISS will enable NASA to see what happens to genetic material in space in real time, rather than looking at a snapshot of DNA before launch and another snapshot of DNA after launch and filling in the blanks.
Rather than being an impediment, NASA can and should be the driver of commerce, the provider of the technology necessary to make some big money in space. The truth is that private enterprise already has a huge presence up there.
I'm a conspiracy theorist. I can't help but look at the lunar landing and go, 'We didn't go to the moon.' We never went there. My dad worked for NASA on the Apollo missions, and I've always felt it's been fake since I was a kid.
I have some NASA memorabilia from the early Apollo days that I can't imagine parting with. I've always wanted to play sort of like a space cowboy, too, like the idea of Captain Kirk. I think that's everybody's dream though, right?
I interned at NASA for five years, and I grew up in Cape Canaveral, and my grandfather was an engineer on the Mercury capsule, and my grandmother was a software engineer. I literally grew up playing on the Mercury capsule prototypes.
I think the crux of the matter was that if we were going to become partners in, for example, the International Space Station, we had to gain the respect of a country like the United States and particularly its space organization, NASA.
I think that when NASA works on a moon shot, they know too well that all of the people working on it must do their job at 110 percent. Sometimes they probably put in 18 hour days, but they're aiming for the moon, and that's what counts.
As a scientist in charge of space sensors and entire space missions before I was at NASA, I myself was involved in projects that overran. But that's no excuse for remaining silent about this growing problem or failing to champion reform.
'Rocket Boys,' for one reason or the other, just happened to strike a chord across country and across world, maybe because it's set in a little coal-mining town. That's why NASA likes it - most of the engineers come from towns very similar.
I love working at NASA, but the part that has been the most satisfying on a day-to-day basis, hour-to-hour, minute-to-minute, has been working on board the space station. Even if I'm just cleaning the vents in the fans, it all is important.
Very little useful science got done in the space station. NASA never did the experiments needed to develop the technologies required for a genuine interplanetary expedition: centrifugal gravity to avoid bodily harm and a truly closed biosphere.
If the United States commits to the goal of reaching Mars, it will almost certainly do so in reaction to the progress of other nations - as was the case with NASA, the Apollo program, and the project that became the International Space Station.
I did not think my chances were very big when I saw some of the other men who were competing for the team. They were a good group, and I had a lot of respect for them. But I decided to give it the old school try and to take some of NASA's tests.
Trillions of dollars in out-of-control entitlement spending cannot be remedied by cuts in NASA, or even in the entire discretionary budget, defense included. Rather, the financial bleeding needs to be staunched where the hole is and nowhere else.
NASA should not be developing its own proprietary version of capabilities it could purchase commercially at much lower cost, especially when we know the agency's bureaucratic tendencies will be to view the commercial versions as competitors to kill.
NASA is an engine of innovation and inspiration as well as the world's premier space exploration agency, and we are well served by politicians working to keep it that way, instead of turning it into a mere jobs program, or worse, cutting its budget.
Instead of being able to look at smaller interesting research projects, I am trying to see the links between all the research NASA does. For me, that's extremely fun because I get to go play and learn about areas of science that I know nothing about.
Many of us in Congress have been calling on the Administration to articulate a bold mission for NASA. It seems that the President is answering that call. I wholeheartedly support his vision for going back to the moon, and from there to worlds beyond.
NASA works for the White House. There are many at NASA that wish they were building a modern replacement for the Shuttle. However, they had marching orders to instead work on other things, some of which should have no place in a research organization.
For years, I longed to hear Armstrong describe what it was like to contemplate Earth from 238,900 miles away. Former Space Center director George Abbey once told me that many NASA astronauts felt that looking at Earth was akin to a religious experience.
You have to budget time for the inevitable problems that come up with children. You have to always be ahead of the game. If your proposal is due at NASA on Friday, it has to be finished on Wednesday because, on Thursday, it could be fevers and head lice.
I can't think of anything specific growing up that pointed me toward NASA at all. I was interested in the Moon landings just about the same as everyone else of my generation. But I never really thought about being an astronaut or working in space myself.
The problem is that many people operate on the assumption that NASA should go to Congress every year with hat in hand and justify it every year. Well, I see it as the greatest economic driver that there ever was. Economic drivers don't need justification.
Archaeologists use datasets from NASA and commercial satellites, processing the information using various off-the-shelf computer programs. These datasets allow us to see beyond the visible part of the light spectrum into the near, middle, and far infrared.
Vegas is the city of temptation. I think, perhaps, it is an experiment by NASA. If we're going to send people to Mars, how will we create false economies and cultures to satisfy them? Vegas has the answer. People go there when they've nothing left to lose.
We actually look to the scientific community to kind of come back to NASA and tell us what the priorities should be. And then at NASA, we try to look within our budget and say, 'What can we accommodate, and what are the most important things for the nation?'
NASA's been one of the most successful public investments in motivating students to do well and achieve all they can achieve, and it's sad that we are turning the program in a direction where it will reduce the amount of motivation it provides to young people.
NewSpace companies are staffed by young, new leaders who worship the giants who got us here, such as the recently passed Neil Armstrong, and are eager to work with NASA to do great things together - but we have to both give them a chance and get out of the way.
I've had young women come to me and say that before they watched 'Voyager' it didn't really occur to them that they could be successful in a higher position in the field of science; girls going to MIT, girls pursuing astrophysics with a view to a career in NASA.
As a card-carrying space nerd and NASA's chief scientist, I love space movies, from 'Star Trek' to 'Star Wars' to my all-time favorite - 'The Dish', an Australian comedy that celebrates that first moment when Neil Armstrong stepped down onto the surface of our moon.
For long-duration exploration missions, NASA is looking for folks with a lot of operational, hands-on experience, people who have been in field-type situations such as military deployments. In my case, I worked in the Congo and in Biosafety Level 4 labs on smallpox.
The one period of glory in NASA was the first nine years when they weren't a bureaucracy yet... and they haven't gotten back to that excitement, that adventurism, and won't. So, I would take most of the NASA budget, and I would turn it into prizes for private sector.
I remember in 1967, when there was that terrible fire on NASA's Apollo 1 rocket that killed three astronauts, my father made pure oxygen and we lit this tiny cup and burned it. Suddenly, we had an unbelievable jet and a fire. You just could see exactly what had happened.
Within NASA, the shuttle is perhaps the least-groundbreaking project. Recall that Apollo was about creating brand-new technologies that did something unprecedented - putting men on the moon. The shuttle is, by comparison, a relic designed to make going into orbit routine.
Congressman Bridenstine's legislative record and his own testimony during his nomination hearing show that he rejects NASA's role in earth science, adopts industry perspectives without critical analysis, and embraces extreme and divisive social views. NASA deserves better.
When I started working at NASA and understanding what the capabilities really were of the space station and the space program, one of the biggest draws for me was the ability to do experiments in space. We can do a number of experiments where gravity is actually a variable.
NASA has been one of the most successful public investments in motivating students to do well and achieve all they can achieve. It's sad that we are turning the programme in a direction where it will reduce the amount of motivation and stimulation it provides to young people.
