Why is Saturn V black and white?
There’s a pretty cool answer to this one… it all boils down to temperature. The Saturn V was painted predominantly white to keep the craft cool as it sat on the launch pad in the hot Florida sun. Holding down the rocket’s body temperature reduced fuel boil-off and improved overall safety.
What is in rocket exhaust?
For rocket propulsion the fuel and oxidizer are usually stored as either a liquid or a solid. When a hydrogen-carbon-based fuel (like gasoline) burns, the exhaust includes water (hydrogen + oxygen) and carbon dioxide (carbon + oxygen). But the exhaust can also include chemical combinations from the oxidizer alone.
How fast did the Saturn 5 go?
Blasting away from Earth According to NASA data, Saturn V reached an altitude of 334.436 km and a speed of 10.423 km/s, at which time the engines were shut down. This velocity was less than the escape velocity for that altitude (see the Calculations section below), but it was sufficient to take Apollo 11 to the Moon.
Why are missiles black and white?
The ones you see with the black and white “checkerboard” pattern were those used in testing and for research purposes. They were painted that way to improve contrast against various sky backgrounds, and to enable rotation of the rocket to be easily seen and measured.
Do rockets hurt the ozone?
When solid-fuel rockets launch, they release chlorine gas directly into the stratosphere, where the chlorine reacts with oxygen to form ozone-destroying chlorine oxides. Soot and aluminum oxide in rocket oxide depletes upper-atmosphere ozone, which shields the Earth’s surface from damaging ultraviolet rays.
What happens to Saturn V stages?
The first and second stages of the Saturn V fell back to Earth once they were spent. The third stage, known as the S-IVB, was just under 60 feet (18 meters) in length and, once released, temporarily orbited Earth along with the Apollo spacecraft before being reignited to send its hardware into lunar orbit.
