25th commercial resupply services mission to the International Space Station operated by SpaceX. The flight will be conducted under the second Commercial Resupply Services contract with NASA. Cargo Dragon 2 brings supplies and payloads, including critical materials to directly support science and research investigations that occur onboard the orbiting laboratory.
Low Earth Orbit B1067 - Flight Proven ( ) A Shortfall of GravitasMaiden flight of the Vega-C launch vehicle, carrying the LARES-2 passive satellite. It is a 40 cm diameter sphere with laser mirrors to study the Earth gravitational field and relativistic effects. Also onboard are six European research cubesats.
Medium Earth OrbitThe Dual-channel Extreme Ultraviolet Continuum Experiment (DEUCE) is a payload from the University of Colorado. its objective is to observe α Centauri A & B and measure a so-far unstudied part of their extreme ultraviolet light spectrum. These measurements are needed to model stars similar to and smaller than our Sun, as well as understand their effects on planetary atmospheres.
SuborbitalGlonass-K are the third generation of satellite design for GLONASS satellite navigation system. GLONASS is a Russian space-based navigation system comparable to the similar GPS and Galileo systems. This generation improves on accuracy, power consumption and design life. Each satellite is unpressurized and weighs 935 kg, and has an operational lifetime of 10 years.
Medium Earth OrbitThe Suborbital Imaging Spectrograph for Transition region Irradiance from Nearby Exoplanet host stars (SISTINE) is a payload from the University of Colorado. Its objective is to study how light from stars affects the atmospheres of the planets around them, including the gases thought to be signs of life. For this flight, it will measure the ultraviolet light output from α Centauri A and B, two stars of the three-star α Centauri system that are the closest stars to our Sun.
