A Quote by Henry Spencer

Developing expendable rockets is always going to be painful and expensive. Throwing the whole rocket away on each attempt not only costs a lot, it also hampers figuring out just what went wrong because you don't get the rocket back for inspection.

The expense of getting into space is the rocket launch, the rocket itself. Rocket's right now, commercial rockets cost probably somewhere between $50, or $120, or $150 million per launch. And those are all expendable. That is, you've got to buy a new rocket for each launch. So, that really is the critical part. If there was some kind of really, a revolutionary breakthrough and the price of rockets fell by an order of magnitude, I mean, just imagine what that would do as far as getting access to more ordinary people.

I certainly remember building model rockets. It was fun to watch the rocket blast into the air, suspenseful to wonder if the parachute would open to bring the rocket safely back.

Eventually private enterprise will be able to send people into orbit, but I suspect initially it's going to have to be with NASA's help. Whether it's going to be a consortium or one entity remains to be seen. I could be wrong. I could be one of the old fogies! Rocket science is tough, and rockets have a way of failing. It happens. A company has to be willing to bear the risk of its rocket failing. It's a very large capital investment.

What patients want is not rocket science, which is really unfortunate because if it were rocket science, we would be doing it. We are great at rocket science. We love rocket science. What we’re not good at are the things that are so simple and basic that we overlook them.

When I was growing up in Huntsville, Alabama, this is where the space and rocket center was. This is where all of the German rocket scientists came after war and started designing rockets for NASA, for the moon landing and all that.

For me, a rocket is only a means--only a method of reaching the depths of space--and not an end in itself... There's no doubt that it's very important to have rocket ships since they will help mankind to settle elsewhere in the universe. But what I'm working for is this resettling... The whole idea is to move away from the Earth to settlements in space.

Konstantin Tsiolkovsky

When you launch in a rocket, you're not really flying that rocket. You're just sort of hanging on.

Michael P. Anderson

Indeed the early history of rocket design could be read as the simple desire to get the rocket to function long enough to give an opportunity to discover where the failure occurred. Most early debacles were so benighted that rocket engineers could have been forgiven for daubing the blood of a virgin goat on the orifice of the firing chamber.

Norman Mailer

I think I was always able to laugh a lot at the industry - to be detached from it, even if some of the other models weren't. Jeez - it's hardly rocket science, is it? It's not as if you can get to be a better model..... .you can either get away with it, or you cant? And most of them were also acutely aware of the passage of time.....and how it would affect their careers.

A lot of the progress in machine learning - and this is an unpopular opinion in academia - is driven by an increase in both computing power and data. An analogy is to building a space rocket: You need a huge rocket engine, and you need a lot of fuel.

Rocket science is tough, and rockets have a way of failing.

Sally Ride

As to rocket ships flying between America and Europe, I believe it is worth seriously trying for. Thirty years ago persons who were developing flying were laughed at as mad, and that scorn hindered aviation. Now we heap similar ridicule upon stratoplane or rocket ships for trans-Atlantic flights.

On Apollo 11 in route to the Moon, I observed a light out the window that appeared to be moving alongside us. It was either the rocket we had separated from, or the 4 panels that moved away when we extracted the lander from the rocket and we were nose to nose with the two spacecraft. So in the close vicinity, moving away, were 4 panels. And i feel absolutely convinced that we were looking at the sun reflected off of one of these panels.

Buzz Aldrin

I recall a lecture by John Glenn, the first American to go into orbit. When asked what went through his mind while he was crouched in the rocket nose-cone, awaiting blast-off, he replied, "I was thinking that the rocket has 20,000 components, and each was made by the lowest bidder."
