In 2008, more than 150 Earth observation satellites were in orbit, recording data with both passive and active sensors and acquiring more than 10 terabits of data daily. [1] By 2021, that total had grown to over 950, with the largest number of satellites operated by US-based company Planet Labs. [4]
Lunar lander. First spacecraft to do a soil analysis of any world. Returned more than 20,000 photos. [15] November 7 US: Surveyor 6: Atlas SLV-3 Agena-D Moon Success Lunar lander. First spacecraft to be launched from the surface of the Moon. It lifted itself to a height of about 3 meters. [16] November 29 Australia: WRESAT: Sparta: Earth: Success

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 ...
Some 5,000 satellites currently orbit Earth, beaming back data about our little blue planet from the vantage point of space. The results can be surprising, altering human perception of the ground ...
This is a list of satellites in geosynchronous orbit (GSO). These satellites are commonly used for communication purposes, such as radio and television networks, back-haul, and direct broadcast. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do.
At the speed technology improves, many satellites are stuck operating obsolete hardware not long after launch. But a San Francisco company founded in 2010,… Why hundreds of mini satellites are ...
95 of the 99 built satellites were launched between 1997 and 2002. [clarification needed] Four satellites were kept on the ground as spares. The 95 satellites were launched over twenty-two missions (nine missions in 1997, ten in 1998, one in 1999 and two in 2002).
