  Apogee, Perigee & Period

The perigees (point of the orbit closest to the Earth's center of mass) of the satellites range from 437km to 49,551km, with the average perigee being 8,477.3km from the Earth, while the apogees (point of the orbit farthest from the Earth's center of mass) of the satellites range from 465km to 191,451km, with the average apogee being 16,473.0km from the Earth. The longest period a satellite takes to orbit around the Earth is 2,475 minutes.

  Satellite Mass

The launch masses (include fuel) of the satellites range from 1kg to 4,500kg, while the dry masses (excluding fuel) of the satellites range from 77kg to 2,200kg.


Highlights on some of the satellites launched via Delta 2:

SMAP.

SMAP Launch and Deployment Sequence

Operated by National Aeronautics and Space Administration (NASA) of USA, SMAP is a government satellite launched for the purpose of earth observation (Earth Science).

Constructed by Jet Propulsion Laboratory (NASA) (USA), it was launched into space on 31 January 2015 using Delta 2 as the launch vehicle from Vandenberg AFB. SMAP orbits around the Earth as a sun-synchronous LEO satellite.

SMAP is designed to operate in space for a lifetime of 3 years. It orbits around the Earth with the COSPAR ID 2015-003A and NORAD ID 40376.

With an orbital eccentricity of 1.85E-03, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 660km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 686km. It takes 98 minutes to orbit the Earth at an inclination of 98 degrees to the equatorial plane of the Earth.

ELFIN-A.

UCLA sends student-built satellite into space

ELFIN-A is a commercial and civil satellite operated by University of California (USA) for the purpose of space science.

Delivered via Delta 2 (launch vehicle) from Vandenberg AFB, it was launched into space on 15 September 2018 and orbits the Earth as a polar LEO satellite. ELFIN-A was constructed by University of California (USA).

ELFIN-A has a launch mass of 4 kg and orbits around the Earth with the COSPAR ID 2018-070E and NORAD ID 43617.

With an orbital eccentricity of 1.90E-03, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 443km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 469km. It takes 94 minutes to orbit the Earth at an inclination of 93 degrees to the equatorial plane of the Earth.

Icesat-2.

ICESat-2 Elevates Our View of Earth

Icesat-2 is a government satellite operated by National Aeronautics and Space Administration (NASA) (USA) for the purpose of earth science (Laser Imaging).

Delivered via Delta 2 (launch vehicle) from Vandenberg AFB, it was launched into space on 15 September 2018 and orbits the Earth as a polar LEO satellite. Icesat-2 was constructed by Northrup Grumman Information Systems (USA).

Icesat-2 has a launch mass of 1,515 kg and is expected to have a operational lifetime of 3 years. It navigates with the COSPAR ID 2018-070A and NORAD ID 43613.

With an orbital eccentricity of 9.51E-04, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 455km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 468km. It takes 94 minutes to orbit the Earth at an inclination of 93 degrees to the equatorial plane of the Earth.
