Liquid oxygen
Robert Hutchins Goddard's most important achievement was building the world's first liquid-fueled rocket and testing it. In doing this he solved many technical problems such as fuel valving for throttle, start and stop, fuel injection, engine cooling and ignition. Goddard developed the technique of having the liquid oxygen cool the combustion chamber on its way from the fuel tank. This method is still in use and therefore his investigations have definitely improved the knowledge of space travel. Robert Goddard's contributions to missilery and space flight would make a lengthy list. Below are some of Dr. Goddard's firsts. Ø Explored the practicality of using rocket propulsion to reach high altitudes and even the moon (1912) Ø Proved that a rocket will work in a vacuum, that it needs no air to push against Ø Developed and shot a liquid fuel rocket (March 16, 1926, Auburn, Mass.) Ø Shot a scientific payload (barometer and camera) in a rocket flight (1929, Auburn, Mass.) Ø Used vanes in the rocket motor blast for guidance (1932, New Mexico) Ø Developed gyro control apparatus for rocket flight (1932, New Mexico) Ø Received U.S. patent in idea of multi-stage rocket (1914) Ø Developed pumps suitable for rocket fuels Ø Launched a rocket with a motor pivoted on gimbals under the influence of a gyro mechanism (1937)
No, Goddard made ballistic missiles but the U.S. military ignored him as the artillery that they had could obviously carry much larger explosive payloads, so Goddard's missiles obviously were of no military value. It took the German V-2 to show the military value of missiles, but the military still largely ignored Goddard and used Nazi scientists to develop military ballistic missiles instead.
You wont need any energy but, you can still use a rocket.
I think it is because of air resistance. Think about it, when objects fly up in the atmosphere they still must get past the air molecules floating around. The rocket tips being sharper allows the rocket to "slice" in between the molecules, which makes the rocket fly faster and easier. If the top was flat, the rocket would have to "push" the molecules out of the way, which would slow the rocket down.
It blew up while still in the earths atmosphere, not when it was in space
no he died in world war 2 from cancer.

The ancient Romans invented the circus, which we still have.
There is no one in a rocket ship heading to Mars.
Robert Hooke was definitely not remembered for mathematics, but he did invent a few theories that are still used today. He is most remembered for his microscopic discoveries of organisms. His most popular book was the Micrographia, which had a large number of detailed pictures of tiny organisms.
