Model of a Galileo satellite. This is a list of past and present satellites of the Galileo navigation system.The fully operational constellation will nominally consist of 30 satellites in Medium Earth Orbit, with 24 active and 6 spares equally divided into 3 orbital planes in a Walker 24/3/1 configuration.
These testbed satellites were followed by four IOV Galileo satellites that are much closer to the final Galileo satellite design. The search and rescue (SAR) feature is also installed. [132] The first two satellites were launched on 21 October 2011 from Centre Spatial Guyanais using a Soyuz launcher, [133] the other two on 12 October 2012. [134]
First Galileo launch on a Falcon 9 and overall twelfth launch of Galileo satellites, carrying satellites Patrick and Julina. Originally planned to launch on Soyuz ST-B, but scrapped due to geopolitical factors. Then moved to Ariane 6, which was also scrapped due to delays. Europe contracted SpaceX to launch the two pairs aboard Falcon 9.
Voyager 2, launched August 1977, operational – flybys of Jupiter, Saturn, Uranus, and Neptune; extended mission to explore interstellar medium; first spacecraft to Uranus and Neptune; Galileo, launched October 1989, completed – Jupiter and its moons; New Frontiers program
Second and last Galileo launch on a Falcon 9 and overall thirteenth launch of Galileo satellites, carrying two satellites. Originally planned to launch on Soyuz ST-B, but scrapped due to geopolitical factors. Then moved to Ariane 6, which was also scrapped due to delays. Europe contracted SpaceX to launch the two pairs aboard Falcon 9. 19 September
Galileo observed the Loki volcano (largest in the Solar System) and a new eruption in the southern region of the moon. I33 102 (63) 17 January 2002 This was the closest of all the flybys of Io. The moon provided a gravity-assist necessary for Galileo ' s ultimate collision course with Jupiter.
Two BlackSky satellites were launched as part of the SXRS-2 rideshare mission. 5 December 00:19:20 [152] Soyuz ST-B / Fregat-MT: VS26 Kourou ELS: Arianespace: Galileo FOC FM23: ESA: Medium Earth: Navigation: In orbit: Operational Galileo FOC FM24: ESA: Medium Earth: Navigation: In orbit: Operational Eighth Galileo launch with Soyuz ST-B ...
When they did fly again, Galileo would have to compete with high-priority Department of Defense launches, the tracking and data relay satellite system, and the Hubble Space Telescope. By April 1986, it was expected that the Space Shuttles would not fly again before July 1987 at the earliest, and Galileo could not be launched before December 1987.
