Satellite Tracking provides detailed real-time and pass predictions for Earth orbiting satellites. See A Satellite Tonight shows you where to look with Google Street View. Uphere.Space real time tracking and predictions. As soon as new satellites are launched this application begins tracking them.
NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
Communication system. [edit] The radio communication system of Voyager 1 was designed to be used up to and beyond the limits of the Solar System. It has a 3.7-metre (12 ft) diameter high-gain Cassegrain antenna to send and receive radio waves via the three Deep Space Network stations on the Earth. [ 21 ]
That distance surpassed the record set by NASA’s 1966 Gemini 11 mission, which reached 853 miles (1,373 kilometers) during its trek around Earth. NASA’s Apollo missions traveled farther but ...
The Chandra X-ray Observatory (CXO), previously known as the Advanced X-ray Astrophysics Facility (AXAF), is a Flagship-class space telescope launched aboard the Space Shuttle Columbia during STS-93 by NASA on July 23, 1999. Chandra was sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high angular ...
Deep Space Climate Observatory (DSCOVR; formerly known as Triana, unofficially known as GoreSat[ 3 ]) is a National Oceanic and Atmospheric Administration (NOAA) space weather, space climate, and Earth observation satellite. It was launched by SpaceX on a Falcon 9 v1.1 launch vehicle on 11 February 2015, from Cape Canaveral. [ 4 ]
Webb operates in a halo orbit, circling around a point in space known as the Sun–Earth L 2 Lagrange point, approximately 1,500,000 km (930,000 mi) beyond Earth's orbit around the Sun. Its actual position varies between about 250,000 and 832,000 km (155,000–517,000 mi) from L 2 as it orbits, keeping it out of both Earth and Moon's shadow.
Proxima Centauri is the nearest star to Earth after the Sun, located 4.25 light-years away in the constellation Centaurus. It is a small, low-mass star, too faint to be seen with the naked eye, with an apparent magnitude of 11.13. Its Latin name means the 'nearest [star] of Centaurus'. Proxima Centauri is a member of the Alpha Centauri star ...
