From the planetary frame of reference, the ship's speed will appear to be limited by the speed of light — it can approach the speed of light, but never reach it. If a ship is using 1 g constant acceleration, it will appear to get near the speed of light in about a year, and have traveled about half a light year in distance. For the middle of ...

Its third flight took place on January 16, 2022, from Mojave Air and Space Port; the flight lasted 4 hours 23 minutes and reached altitude of over 23,490 feet (7,160 m) and top speed of 330 km/h (180 kn). [31] It made its fourth flight on February 24, 2022.
In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most massive body.
The spaceplane also shared its name with NASA's prototype Space Shuttle orbiter, as well as the aircraft carrier USS Enterprise. It was rolled out on 7 December 2009. [16] SpaceShipTwo made its first powered flight in April 2013. Richard Branson said it "couldn't have gone more smoothly". [17]
The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [ 1 ] was achieved on 3 October 1967, [ 2 ] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet ...

Huygens (/ ˈ h ɔɪ ɡ ən z / HOY-gənz) was an atmospheric entry robotic space probe that landed successfully on Saturn's moon Titan in 2005. Built and operated by the European Space Agency (ESA), launched by NASA, it was part of the Cassini–Huygens mission and became the first spacecraft to land on Titan and the farthest landing from Earth a spacecraft has ever made.
