The ISS observes Greenwich Mean Time (UTC/GMT). The shuttles also had UTC clocks so that the astronauts could easily figure out what the "official" time aboard ISS was. [4] In 2019, a test flight of the Boeing CST-100 Starliner spacecraft suffered a mission anomaly through an incorrectly set Mission Elapsed Time on the vehicle. [5]
At the moment, different space organizations still use their own time zones for their onboard chronometers and their two-way communications systems. The ESA said doing so "will not be sustainable ...
The record for most time in space is held by Russian cosmonaut Oleg Kononenko, who has spent 1,111 days in space over five missions. He broke the record of Gennady Padalka on 4 February 2024 at 07:30:08 UTC during his fifth spaceflight aboard Soyuz MS-24 / 25 for a one year long-duration mission on the ISS . [ 21 ]
Notable test flights of spaceflight systems may be listed even if they were not planned to reach space. Some lists are further divided into orbital launches (sending a payload into orbit, whether successful or not) and suborbital flights (e.g. ballistic missiles, sounding rockets, experimental spacecraft).

Interplanetary spaceflight or interplanetary travel is the crewed or uncrewed travel between stars and planets, usually within a single planetary system. [1] In practice, spaceflights of this type are confined to travel between the planets of the Solar System .
The astronauts - 23 men and one woman, with an average age of about 47 - were aboard the International Space Station for missions that took place from November 2011 to June 2018, with a total of ...
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
