Designed for space science, TESS is a government satellite operated by National Aeronautics and Space Administration (NASA) (USA).
Constructed by NASA/MIT (USA), it was launched into space on 18 April 2018 using Falcon 9 as the launch vehicle from Cape Canaveral. TESS orbits around the Earth as a Elliptical satellite.
With a launch mass of 362kg, TESS is designed to operate in space for a lifetime of 20 years. It orbits around the Earth with the COSPAR ID 2018-038A and NORAD ID 43435.
With an orbital eccentricity of 9.53E-01, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 258km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 268,488km. It takes 8,758 minutes to orbit the Earth at an inclination of 30 degrees to the equatorial plane of the Earth.
