S4 CROSSOVER is a technology demonstration mission to obtain flight heritage testing for a prototype payload host platform. It will test supporting future payloads, including a Globalstar transmitter and an Iridium transceiver, as well space environmental instruments to characterize the radiation and plasma densities to which the payloads will be exposed. S4 CROSSOVER is self powered and operates independently of the Astra second stage to which it is permanently attached. Re-manifested from SXRS-6 / Transporter-3, OreSat0 is a fully open source CubeSat satellite system built from scratch by students at Portland State University. Slated to be Oregon’s first satellite, the 1U CubeSat provides flight heritage for the modular, expandable, open source, and education-friendly OreSat bus. OreSat0 paves the way for OreSat, a NASA CSLI program 2U CubeSat with a global climate science and STEM outreach mission.
Sun-Synchronous OrbitThe first flight dedicated to the launch of the Internet constellation of GalaxySpace, a private company, planning the total deployment of more than 1000 satellites in earth orbit. The satellites broadcast in 5G, with a capacity of 10 Gb.
Low Earth OrbitThe Geostationary Operational Environmental Satellite T (GOES-T) is the third satellite in NOAA’s advanced GOES-R series. It is meant to operate as GOES West and work in tandem with GOES-16, which operates in the GOES East position
Geostationary Transfer OrbitStriX β is a Japanese synthetic aperture radar satellite built by Synspective as a demonstrator for their planned 25 satellite constellation. It will feature an X-band synthetic aperture radar. StriX β is an upgraded version of the StriX α prototype. The satellite features two deployable panes, one side carrying solar cells, the other carrying the X-band radar antenna. The StriX satellite constellation can target data with a ground resolution of 1-3 m, single polarized (VV), and a swath width of more than 10-30 km. The StriX observation modes are Stripmap and Sliding Spotlight mode and each satellite has an SAR antenna that is 5 meters in length and stowed during launch. The simple design of the satellites allows for affordable development of the constellation. StriX β was planned to be launched in 2021 on a Soyuz-2-1a Fregat or Soyuz-2-1b Fregat rideshare mission, but as this mission was delayed, it was re-booked on a dedicated Electron KS launch. Synspective is planning a constellation of 25 satellites called StriX, comprised of 100-kilogram satellites capable of imaging at a resolution of one to three meters. By 2022 the company plans to have six satellites in orbit. The company has not set a date by which it hopes to achieve 25 satellites.
