UnverifiedSpaceShipTwo uses an air-launch approach: it is carried by the mothership WhiteKnightTwo to an altitude of about 15 kilometers and released, after which the spaceship ignites its rocket engine and climbs to suborbital space at an altitude of about 80–90 kilometers.79% similarVerifiedAn orbital flight requires the spacecraft to reach the first cosmic velocity of approximately 7.9 km/s at an altitude of about 200 km or above.69% similarUnverifiedVoyager 1 was launched in 1977 and is currently more than 24 billion kilometers from Earth, making it the farthest human-made object.64% similarUnverifiedOrbital-class launch vehicles refer to rockets capable of delivering payloads into Earth orbit or higher-energy orbits, whose flight speeds and altitudes far exceed those of suborbital tests.64% similarUnverifiedStarship has a payload capacity far exceeding that of the Falcon rocket, allowing it to carry more and larger satellites into orbit in a single launch.59% similar
