STPSat 3 is a copy [clarification needed] of the STPSat-2 satellite, adapted to carry six experiments, including a module designed to host various space situational awareness sensors and a pair of space environment sensors. STPSat 3 launched on 19 November 2013, on the ORS-3 Minotaur 1 launch, along with 28 CubeSats. [10]
By April 2020, after further delays and cost overruns, it was expected to launch in January 2021, as a payload on a U.S. Air Force Space Test Program satellite (STPSat 6, part of STP-3 launch). [11] STPSat-6 is destined for an orbit slightly above the geostationary orbit. [12]
The third satellite has been launched on November 10, 2022 [3] with two more satellites scheduled to be launched. [4] [5] In addition, the TSI Calibration Transfer Experiment, launched on the U.S. Air Force Space Test Program Satellite-3 (STPSat-3) on November 19, 2013, is also part of JPSS.
Obtain daily measurements of solar spectral irradiance between 0.3 and 2 μm with a spectral resolution of at least 1/30, an accuracy of 0.03%, and long-term repeatability of better than 0.01%/yr. To improve the understanding of how and why solar irradiance varies, estimate past and future solar behavior, and investigate climate responses.
Landsat 9 is an Earth observation satellite launched on 27 September 2021 from Space Launch Complex-3E at Vandenberg Space Force Base on an Atlas V 401 launch vehicle. [12] NASA is in charge of building, launching, and testing the satellite, while the United States Geological Survey (USGS) operates the satellite, and manages and distributes the data archive. [13]
