Heaviest satellite launched by University Of Michigan And NASA Earth Science Technology Office into space at 29 kg

CYGNSS-A is a government satellite operated by University of Michigan and NASA Earth Science Technology Office (USA) for the purpose of earth observation (Radar Imaging and Earth Science).

Delivered via Pegasus (launch vehicle) from Orbital ATK L-1011, it was launched into space on 15 December 2016 and orbits the Earth as a non-polar inclined LEO satellite. CYGNSS-A was constructed by Southwest Research Institute (USA).

CYGNSS-A has a launch mass of 29 kg and navigates with the COSPAR ID 2016-078D and NORAD ID 41887.

Taking 95 minutes to orbit the Earth, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 515km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 537km. The eccentricity of the orbit is 1.60E-03 and it orbits at an inclination of 35 degrees to the equatorial plane of the Earth.
