John Glenn Quotes

I don't think we're going to build a 50-person spacecraft or a 100-person spacecraft.

I founded a launch company called International Microspace when I graduated medical school in 1989. We were trying to build a microsatellite launcher.

Lighter computers and lighter sensors would let you have more function in a given weight, which is very important if you are launching things into space, and you have to pay by the pound to put things there.

We can put a satellite in orbit in 60 days.

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.

My expertise is the space program and what it should be in the future based on my experience of looking at the transitions that we've made between pre-Sputnik days and getting to the moon.

It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will.

Then during the mission itself, I used the space shuttle's robot arm to release a satellite into orbit.

What I'm trying to do is, is to make a significant difference in space flight. And help make space flight accessible to almost anyone.

We do need different types of propulsion to get to Mars. I wrote one of the first Ph.D. theses on that in the 1960s.

Claiming that solid rockets are necessary for a heavy-lift launcher is obvious nonsense.

Britain should definitely be part of a Mars mission.

If we drive down the cost of transportation in space, we can do great things.

Man must at all costs overcome the Earth's gravity and have, in reserve, the space at least of the Solar System.

And the first flight of the tether satellite happened in '92, and I was the backup on that flight.

I study orbital dynamics as a hobby. My idea of a good time is sitting down and drawing on that knowledge to imagine a space mission from beginning to end, getting as many details right as I can.

If you're going to go into space, you have to have an objective, a mission. Where do you want to go? Earth orbit? The moon? Mars? What's the technology to get there? You develop the technology for the mission.

There are few aspects of everyday life that aren't touched by the technologies developed for space travel.

Micro satellites, about the size of a loaf of bread, are going to be going into space more and more.

Russia can offer state-of-the-art technology, .. For example, we can help other countries launch space devices such as satellites.

There is good science you can do in space. There is stuff there you cannot do on Earth and we can gain understanding from it.

Well, it's still a bit uncertain, but I will do the consulting, and I'll see how I can contribute. But I'm sure whatever I do will involve the space program. That's where my passion is.

My background is in physics, so I was the mission specialist, who is sort of like the flight engineer on an airplane.

The space elevator's not just another competitive technology, promoted by people who simply like the idea of diminishing the luster of the thrusters. It would open wide the doors to space.

With the mission to Mars, the whole world wants to get involved. So we actually have 13 different space agencies from around the world working on the global exploration road map.
