The use of tardigrades in space, first proposed in 1964 because of their extreme tolerance to radiation, began in 2007 with the FOTON-M3 mission in low Earth orbit, where they were exposed to space's vacuum for 10 days, and reanimated, just by rehydration, back on Earth. In 2011, tardigrades were on board the International Space Station on STS-134.
Tardigrades have survived exposure to space. In 2007, dehydrated tardigrades were taken on the FOTON-M3 mission and exposed to vacuum, or to both vacuum and solar ultraviolet, for 10 days. [ 15 ] Back on Earth, more than 68% of the subjects protected from ultraviolet were reanimated by rehydration, and many produced viable embryos.
Their adaptability has been tested in Low Earth Orbit, according to Guidetti et al. (2012), and the results are crucial for preserving space and lunar habitats for life. [13] Tardigrades can undergo all five types of cryptobiosis, reducing their metabolism to less than 0.01% and their water content to 1% compared to their normal state.
On previous space missions, tardigrades were exposed to the open vacuum of space and some were able to live for a period of time. [ 53 ] [ 54 ] There is no real danger they will spread across the Moon, [ 53 ] but this "tardigrade affair" attracted the criticism of professionals who pointed out the lack of both planetary protection measures and ...
A significant event related to the Kessler Syndrome occurred on August 9, 2024, when a Chinese Long March 6A rocket broke apart in low-Earth orbit, creating a cloud of hundreds of debris fragments. The US Space Command confirmed this breakup, and it has been tracked by multiple space debris-tracking organizations.
The simulation is centered on a typical Space Shuttle mission to service a space station. Mission phases include Earth Lift-Off, Orbital Rendezvous, Approach and Alignment and Docking. [2] It was released for the Apple II in 1982, [2] receiving positive feedback from reviewers. [3]

The principles of flight dynamics are used to model a vehicle's powered flight during launch from the Earth; a spacecraft's orbital flight; maneuvers to change orbit; translunar and interplanetary flight; launch from and landing on a celestial body, with or without an atmosphere; entry through the atmosphere of the Earth or other celestial body ...
