Most launches from Earth. 10 launches. Frederick W. Sturckow (USA), Space Shuttle and SpaceShipTwo (1998–2024) Note: The six SpaceShipTwo flights surpass the U.S. definition of spaceflight (50 mi (80.47 km)), but fall short of the Kármán line (100 km (62.14 mi)), the definition used for FAI space recordkeeping.
At times the number of people present in space at the same time has climbed since 1995 above 13 with a record 17 in orbit in 2023 on two space stations. The ISS has hosted the most people in space at the same time, reaching 13 for the first time during the eleven day docking of STS-127 in 2009.
The highest number of people at the same time on one space station has been 13, first achieved with the eleven day docking to the ISS of the 127th Space Shuttle mission in 2009. The record for most people on all space stations at the same time has been 17, first on May 30, 2023, with 11 people on the ISS and 6 on the TSS.
The Earth and the Moon will most likely be destroyed by falling into the Sun, just before the Sun reaches the largest of its red giant phase when it will be 256 times larger than its current size. Before the final collision, the Moon will possibly spiral below Earth's Roche limit , breaking into a ring of debris, most of which would fall to ...
24 people have traveled beyond low Earth orbit and either circled, orbited, or walked on the Moon. Of the 44 countries whose citizens have traveled into Earth orbit, 25 have flown a single space traveler, and four others (Belgium, Bulgaria, the Netherlands, and the United Kingdom) have flown two each. 94% of all space travelers have been ...
The satellites orbit in a circular low Earth orbit at about 500 km (310 mi) altitude in a high-inclination orbit for a planned six to twelve-month duration. The satellites communicate with three testing ground stations in Washington State and California for short-term experiments of less than ten minutes duration, roughly daily.
List of active Solar System probes. This is a list of active space probes which have escaped Earth orbit. It includes lunar space probes, but does not include space probes orbiting at the Sun–Earth Lagrangian points (for these, see List of objects at Lagrangian points ). A craft is deemed "active" if it is still able to transmit usable data ...
The orbit is entirely outside the Van Allen belts to avoid radiation damage to TESS, and most of the orbit is spent far outside the belts. Every 13.70 days at its perigee of 108,000 km (67,000 mi), TESS downlinks to Earth over a period of approximately 3 hours the data it has collected during the just finished orbit. Science objectives
