... measure of rocket performance is the amount of velocity that can be achieved starting from rest, usually called "delta V." Amateur rockets have limited performance but can occasionally provide a delta V of almost 328 ... can provide about 3300 feet per second of delta V. Space travel requires a very large delta V. The first objective of a launch to space is to get into orbit. To remain in orbit ...

We cannot know what is inside a black hole because once an object goes beyond the event horizon of the ...

The shortest journey into space is a sub-orbital hop where a spacecraft goes up and down in an arc trajectory, like a ball flying through the air (this when the rocket is not powerful enough to reach orbit). The first sub-orbital hop was by astronaut Commander ...

... trajectory, C3, delta-V, pork-chop plot, launch window, Mars, Venus flyby '''JBIS Reference Code ''' - 2011.64.204 '''Number of Pages''' - 10 Abstract This paper develops a convenient tool which is capable of ... to expand the flyby mission windows. The procedure of creating a V contour plot for direct trajectories is a straightforward full- factorial computation with two input variables of departure and arrival dates ...

... stage of the Saturn V, and many other launch vehicles, was liquid oxygen (LOX) and RP1, a special grade of kerosene. Energy is measured in joules. One joule is equal to one Watt ... joules, equal to half the mass multiplied by the velocity squared. For example, one joule is the energy in a two kilogram mass moving at one meter per second. Imagine a two kilogram hammer swung at one meter per second. Mega-joule is a million joules. This LOX/RP1 mixture has a specific energy of 4.5 mega ...

... arm out and wave it around, you are feeling the atmosphere. The Earth's atmosphere is composed mostly of nitrogen and oxygen molecules with other minor gases. We breathe the oxygen ... upward we travel from the surface. Ten miles up the pressure is one-ninth of the surface; 15 miles up it is one-twenty-seventh of the surface. Commercial jets fly about five miles up and the air is very thin. The edge of space is roughly 60 miles up and the air is so thin that commercial planes cannot fly and ...

... —28 years ago. Voyager 1 has now traveled over 8.6 billion miles and is the furthest man-made object from Earth. The longest manned space journey was carried out ... they have spent off the Earth on all their flights, Russian cosmonaut Commander Sergei Krikalev is the winner, with 803 days total so far ---- Answer provided by Hazel McAndrews Image:K2S ...

... about 17,000 miles per hour to orbit and to maintain a space orbit. There is a range of speeds at which the different satellites travel. Because of the laws of ...

With a spacesuit on, jumping is going to be a bit difficult, and very dangerous if you come down wrong. From ... about ten feet or about seven times as high. What's disorienting is that, because of the lower gravity, while less than a second is spent in the air here on Earth, a ...

... be symmetrical. If you describe black holes as a gravitational well in space where matter is continuously falling in, the opposite solution in time would be an area of space where ... actually allow matter to escape into space. This is a white hole. Now, if there is a rotating black hole in space, there is a chance for an object to fall into a ... within our Universe or perhaps be connected to different universes. Now that I have described what it is, I must emphasize that scientists currently do not believe white holes or worms holes ...
