Buzz Aldrin Quotes

If you go on a journey to Mars and get into deep space, there is several hundred times, maybe 300 times the radiation.

Asteroids are deep-space bodies orbiting the Sun, not the Earth, and traveling to one would mean sending humans into solar orbit for the very first time. Facing those challenges of radiation, navigation and life support on a months-long trip millions of miles from home would be a perfect learning journey before a Mars trip.

I think a Moon base is not necessary to get to Mars, but I think it will be helpful. It would give you a chance to develop and mature some systems; long duration, deep space stuff; and you're close enough to get some help, via radio from Earth.

The life expectancy of people going to Mars may be decreased by the higher level of radiation that they receive.

Exploring Mars is a far different venture from Apollo expeditions to the moon; it necessitates leaving our home planet on lengthy missions with a constrained return capability.

I'm in favor of changing the destination of humans. There are a lot of manned missions that can be done, but not in the direction of the moon.

Human beings are fragile things, and for the period of time it takes to get them to Mars and back, you have dangerous radiation from the sun and the galaxy. We have to think about issues like that.

It is only by freeing NASA from routine human transport to low-Earth orbit that we can afford to once again see American astronauts exploring distant worlds.

Basically, most good science in space flight has to do with the behavior of the human body in space. That is where we are lacking info, and where info can only be obtained by flying in space.

The big reason why we don't have space colonies and regular trips to the moon is that flying into outer space is just plain 'hard.' The business of safely transporting people off the Earth is a costly affair that requires a lot of technology.

My key aim is to get man on the surface of Mars by the mid-2030s.

'The Martian' may be fiction, but at NASA, we are working to make it a reality.

During my 8 years as chairman, I had the privilege to peer into the future to see dynamic citizen astronauts returning to and from the heavens which we can expect in the future.

I am excited to think that the development of commercial capabilities to send humans into low Earth orbit will likely result in so many more Earthlings being able to experience the transformative power of space flight.

I don't go along with going to Moon first to build a launch pad to go to Mars. We should go to Mars from Earth orbit. We have already been to the Moon; we've already practiced.

The space shuttle is a better and safer rocket than it was before the Challenger accident.

We're not going to get humans to Mars until at least the mid-2030s, and the world is going to change by then.

Back in the days of Apollo, sending humans to the moon was the only viable way to get the scientific data we wanted. But now, with our computer and robotics technology, there's very little an astronaut can do on Mars that a well-designed rover can't.

Research into manned spaceflight is shifting from low-Earth orbit to destinations much further away, like Mars and the asteroid belt. But society will have to invent many new technologies before it can plausibly send people to those distances.

The years of space flight since the orbiting of Sputnik I back in 1957 had produced many fascinating results, but they had also brought a realization of the many problems that surrounded the use of rockets for space flight.

When I hear about a man talking about having been taken out to the Van Allen space radiation belt of space ships that were essentially the same thing as the DC-8, I've got to tell you, I mean, if we're talking about this man's credibility, that certainly raises some questions in my mind about his credibility.

I was working as a flight director on the Gemini IX mission, and it seemed almost overnight I was picking up the responsibilities for the Apollo Program.

There's a world of insights to be gained into human health and disease by understanding how gravity and space radiation influence biology.

Getting to space for satellites is tough. Getting to space with humans aboard is even tougher.

Mars does not have an atmosphere and does not have a magnetic field today, so the planet doesn't have the protection from radiation that our atmosphere and magnetic fields provide us on Earth.
