The satellites were intended to test Distant retrograde orbit. [33] Tracking data appears to show China is attempting to salvage spacecraft and they appear to have succeeded in reaching their desired orbit. [34] [35] China: Queqiao-2: Moon: Success
The Hubble Space Telescope Comparison between many space telescopes by diameter Overview of active and future telescopes (as of January 2021) This list of space telescopes ( astronomical space observatories ) is grouped by major frequency ranges : gamma ray , x-ray , ultraviolet , visible , infrared , microwave , and radio .

These designations have been applied to most United States military satellites since 1984, and replaced the earlier OPS designation. As of June 2022, USA designations have been assigned to 437 space satellites. There is not always a one-to-one mapping between launch vehicles and mission spacecraft.
Mission consists of two spacecraft, which were the first spacecraft to reach Earth–Moon Lagrangian points. Both moved through Earth–Moon Lagrangian points, and are now in lunar orbit. [34] [35] WIND: Sun–Earth L 2: NASA: Arrived at L 2 in November 2003 and departed April 2004. Gaia Space Observatory: Sun–Earth L 2: ESA: Launched 19 ...

Part of a future constellation of 25 satellites to provide global coverage.
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
It was believed that the cutoff for round objects is somewhere between 100 km and 200 km in radius if they have a large amount of ice in their makeup; [1] however, later studies revealed that icy satellites as large as Iapetus (1,470 kilometers in diameter) are not in hydrostatic equilibrium at this time, [2] and a 2019 assessment suggests that ...
