The first space rendezvous was accomplished by Gemini 6A and Gemini 7 in 1965.. Records and firsts in spaceflight are broadly divided into crewed and uncrewed categories. Records involving animal spaceflight have also been noted in earlier experimental flights, typically to establish the feasibility of sending humans to outer space.
The speed of a spaceship is often expressed in terms of c, the metaphorical speed of light (one cell per generation) which in many cellular automata is the fastest that an effect can spread. For example, a glider in Conway's Game of Life is said to have a speed of c / 4 {\displaystyle c/4} , as it takes four generations for a given state to be ...
SKY Perfect JSAT: Superbird-9 is a SKY Perfect JSAT's fully flexible HTS (High Throughput Satellites) based on Airbus' OneSat product line. 2027 Unknown Unknown TBA: Propellant Unknown LEO: Luxembourg Space Agency: Tanker launch for ISRU Processing System.

When stacked and fully fueled, Starship has a mass of approximately 5,000 t (11,000,000 lb), [c] a diameter of 9 m (30 ft) [17] and a height of 121.3 m (398 ft). [6] The rocket has been designed with the goal of being fully reusable to reduce launch costs; [18] it consists of the Super Heavy booster and the Starship upper stage [19] which are powered by Raptor and Raptor Vacuum engines.
Sub-orbital space flights, being at a much lower speed, do not generate anywhere near as much [further explanation needed] heat upon re-entry. Even if the orbiting objects are expendable, most [ quantify ] space authorities [ example needed ] are pushing toward controlled re-entries to minimize hazard to lives and property on the planet.
On February 2, 2021, Starship SN9 launched to 10 km (6.2 mi) in a flight path similar to SN8. The prototype crashed upon landing because one engine did not ignite properly. [96] A month later, on March 3, Starship SN10 launched on the same flight path as SN9. [97] The vehicle landed hard and crushed its landing legs, and detonated ten minutes ...
The X-43 was a part of NASA's Hyper-X program, involving the American space agency and contractors such as Boeing, Micro Craft Inc, Orbital Sciences Corporation and General Applied Science Laboratory (GASL). Micro Craft Inc. built the X-43A and GASL built its engine.
