Sub orbital means that your path from Kerbin launch is also eventually going to impact Kerbin. So sub-orbital means below orbit. Depending on the terms of the contact, escape trajectory probably means something should be sent beyond Kerbin’s sphere of influence.
What does suborbital mean in Kerbal space program?
A sub-orbital flight is one that doesn’t go in to orbit. What you need is a launch that has an apoapsis between the two altitudes you list, to meet the requirement of the mission, and which then comes back down to Kerbin.
What is an escape trajectory in KSP?
An escape trajectory is one that will leave the current bodies (Kerbin in this case) Sphere of Influence (SOI). It happnes when you are going too fast for its gravity to keep you in orbit (which is always the case when you first enter an SOI!).
What is the main shape of a rocket that follows a sub orbital trajectory?
The rockets follow parabolic or “U-shaped” trajectories, providing nearly vertical paths along their ascent and descent.
What is kerbin escape velocity?
9.81 m/s2 (1 g) Escape velocity. 3 431.03 m/s. Sidereal rotation period. 21 549.425 s.
How far up is Earth’s orbit?
In the 1900s, Hungarian physicist Theodore von Kármán determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. Today, though, the Kármán line is set at what NOAA calls “an imaginary boundary” that’s 62 miles up, or roughly a hundred kilometers above sea level.
Is suborbital really space?
A suborbital rocket requires just about enough speed to be able to fly to about 100km above Earth’s surface. … But scientists say that at the highest point of a suborbital flight one can experience weightlessness although the vessel itself is not floating in space but is in the process of dropping back to Earth.
Which country has the best missile technology in the world?
With the test of the PAD missile, India became the fourth country to have successfully developed an Anti-ballistic missile system, after United States, Russia and Israel.
How high do sounding rockets go?
Sounding rocket, also called Probe Rocket, any unmanned rocket that is designed to probe atmospheric conditions and structure at heights (80–160 km [50–100 miles]) beyond the reach of airplanes and balloons but impractical to explore by means of artificial satellites.
