The escape velocity on the planet Saturn is 35.5 kilometre per second. That is, a body has to be projected with a velocity of 35.5 kilometre per second so that it can escape from the gravitational pull of the planet. (Escape velocity on the earth is about 11.2 kilometre per second.)
The escape velocity from the Moon is about 2.38 km/s. To leave the Moon's surface, a lunar landing module would need to reach this speed to overcome the Moon's gravitational pull.
The escape velocity is given by √(2gR). Since Rmoon = 0.1REarth, and gMoon = 0.16gEarth, the ratio of escape velocities can be found as: √(2gEarthREarth) / √(2gMoonRMoon) = √((2gEarthREarth) / (2gMoonRMoon)) = √((gEarthREarth) / (gMoonRMoon)) = √((gEarth / gMoon) * (REarth / RMoon)) = √((6 * 1) / (0.16 * 0.1)) = √(6.25) = 2.5. So, the ratio of escape velocity from Earth's surface to that from the Moon's surface is 2.5.
If a rocket rises from Earth but never attains escape velocity, it will eventually fall back to Earth due to gravity. The rocket's upward thrust will not be enough to overcome Earth's gravitational pull, causing it to return to the planet's surface.
The speed that ab object must travel at to escape a planet's gravity is called escape velocity. This value varies depending on the mass and diameter of the planet. Here are the escape volcities of the eight planets of our solar system. Mercury: 9,400 mph Venus: 23,000 mph Earth: 25,000 mph Mars: 11,000 mph Jupiter: 133,000 mph Saturn: 77,000 mph Uranus: 48,000 mph Neptune: 53,000 mph Note that escape velocity only takes gravity into account and ignores other forces. An object launched from Earth's surface or from any other planet with a substantial atmosphere at escape velocity would be quickly destroyed and slowed down by air resistance.
The escape velocity on the planet Saturn is 35.5 kilometre per second. That is, a body has to be projected with a velocity of 35.5 kilometre per second so that it can escape from the gravitational pull of the planet. (Escape velocity on the earth is about 11.2 kilometre per second.)

Hydrogen probably cannot exist for a long time on Mars. As you suggest this is because of the planet's fairly low gravity and escape velocity. It's easier for a very light atom or molecule, such as hydrogen, to reach the planet's escape velocity, caused by collisions in the atmosphere.
The simple answer is that unless the rocket achieves escape velocity, the planet it hits would be Mars. Due to the rotation of the planets, if it did reach escape velocity, it would depend on the position of the planets and the path into space it took.
The escape velocity is higher for Earth than for the Moon. Earth's escape velocity is approximately 11.2 km/s, while the Moon's escape velocity is about 2.4 km/s. This is because Earth is more massive and has a stronger gravitational pull compared to the Moon.
The escape velocity from the Moon is about 2.38 km/s. To leave the Moon's surface, a lunar landing module would need to reach this speed to overcome the Moon's gravitational pull.
Escape from Mars was created in 1999.
The escape speed from the surface of the Earth is about 11.2 kilometers per second (about 25,000 miles per hour). This is the speed at which an object must travel to break free from the Earth's gravitational pull and not fall back down.
Each asteroid has its own escape velocity.
Escape Velocity Nova happened in 2002.
Escape Velocity Override happened in 1998.
