A Quote by Henry Spencer

Past experience, on the shuttle and the Titan rockets, suggests that large multi-segment solid rockets have a probability of failure of 0.5 to 1 per cent.

Whether solid rockets are more or less likely to fail than liquid-fuel rockets is debatable. More serious, though, is that when they do fail, it's usually violent and spectacular.

Our royalty statement has been minimal and menial. Really. We don't collect more than a per cent of a per cent of a per cent of a per cent of a per cent of a per cent of a per cent. We get maybe the seventh of 1 percent.

Liz Mitchell

You know most people live ninety per cent in the past, seven per cent in the present, and that only leaves them three per cent for the future.

John Steinbeck

Building and launching rockets has been a lifelong hobby that my son and I share. We regularly travel to Nevada's Black Rock Desert to launch rockets.

Steve Jurvetson

Large solid rockets have never been a very good way to build launchers that might have crews on top, especially because of the problems in getting the crew away from a failing launcher.

The rockets set the bony meadows afire, turned rock to lava, turned wood to charcoal, transmuted water to steam, made sand and silica into green glass which lay like shattered mirrors reflecting the invasion, all about. The rockets came like drums, beating in the night. The rockets came like locusts, swarming and settling in blooms of rosy smoke.

Ray Bradbury

The rockets light! The shuttle leaps off the launch pad in a cloud of steam and a trail of fire.

Sally Ride

If we want to contrast what we have done in the past few years on delivery with what the right hon. and learned Gentleman delivered, let us remember the interest rates at 10 per cent. to 15 per cent., the 1.5 million fewer people in work, the boom and the bust and the borrowing at 8 per cent.

Tony Blair

The top 10 per cent of the US population appropriated 91 per cent of income growth between 1989 and 2006, while the top 1 per cent took 59 per cent.

Ha-Joon Chang

Solid-fuel rockets can't easily be shut down on command.

Sometimes people wonder why aeroplanes are so cheap and rockets are so expensive. Even the most superficial comparison shows one obvious difference: aeroplane engines use outside air to burn their fuel, while rockets have to carry their own oxidisers along.

I've decided to become a member of the Houston Rockets. I feel it's the best place for me and I am excited about joining the Rockets and I'm looking forward to a great season. I want to thank the fans in Los Angeles and wish them the best.

Dwight Howard

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

Henry Spencer

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.

Leroy Chiao

If you're really thinking prayer can stop rockets or bullets, you have to ask why some people do get hit by rockets or bullets. Are they people who no one prayed for? Are they people who God just didn't like? I don't think so.

John Shelby Spong

I want to make rockets 100 times, if not 1,000 times better. The ultimate objective is to make humanity a multiplanet species. Thirty years from now, there'll be a base on the moon and on Mars, and people will be going back and forth on SpaceX rockets.
