Also installed during STS-134 was the 15 m (50 ft) Orbiter Boom Sensor System (OBSS), which had been used to inspect heat shield tiles on Space Shuttle missions and which can be used on the station to increase the reach of the MSS. [149] Staff on Earth or the ISS can operate the MSS components using remote control, performing work outside the ...
Sun–Earth L 1: ESA, NASA: Orbiting near L 1 since 1996. Operational as of 2020. [27] WIND: Sun–Earth L 1: NASA: Arrived at L 1 in 2004 with fuel for 60 years. Operational as of 2019. [28] Wilkinson Microwave Anisotropy Probe (WMAP) Sun–Earth L 2: NASA: Arrived at L 2 in 2001. Mission ended 2010, [29] then sent to solar orbit outside L 2. [30]
At their furthest Mars and Earth can be as far as 401 million km (249 million mi) apart. [191] Mars comes into opposition from Earth every 2.1 years. The planets come into opposition near Mars's perihelion in 2003, 2018 and 2035, with the 2020 and 2033 events being particularly close to perihelic opposition. [192] [193] [194]
The Close Approach happens every two years, but Tuesday's encounter at 38.6 million miles away will be the closest to Earth that Mars gets until 2035
A view from the International Space Station in a low Earth orbit (LEO) at about 400 km (250 mi), with yellow-green airglow visible at Earth's horizon, where roughly at an altitude of 100 km (62 mi) the boundary between Earth and outer space lies and flying speeds reach orbital velocities.
For example, the orbiters collect the scientific data from the Curiosity rover on Mars through near-Mars communication links, transmit the data to Earth through direct links from the Mars orbiters to the Earth ground stations via the NASA Deep Space Network, and finally the data routed through Earth's internal internet.
