The Total and Spectral Solar Irradiance Sensor 2 (TSIS-2) is a satellite designed by NASA to measure the Sun's energy input to Earth. TSIS-2 comprises two instruments, the Total Irradiance Monitor (TIM), and the spectral Irradiance Monitor (SIM). TIM measures total brightness and SIM measures spectral irradiance over a wavelength range that includes 96% of the energy in the solar spectrum. Both instruments are similar to those used for the TSIS-1 mission onboard the International Space Station.
Sun-Synchronous OrbitThe Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO) are the foundational elements of NASA's lunar-orbiting space station "Gateway". The PPE is a 60-kilowatt class solar electric propulsion spacecraft that also will provide power, high-speed communications, attitude control and the capability to move the Gateway to different lunar orbits. The HALO is the pressurized living quarters where astronauts who visit the Gateway, often on their way to the Moon, will work. It will provide command and control and serve as the docking hub for the outpost. HALO will support science investigations, distribute power, provide communications for visiting vehicles and lunar surface expeditions, and supplement the life support systems aboard Orion, NASA’s spacecraft that will deliver Artemis astronauts to the Gateway.
Lunar OrbitTrinity is a three-spacecraft mission from US satellite manufacturer K2 Space, with each satellite deploying to a different orbital regime to prove out K2 Space’s multi-orbit satellite platform. 2 satellites will be dropped off in LEO, 1 remaining in LEO for a period before raising itself to MEO, while the other will immediately begin climbing to MEO and will aim to complete orbit raising within 90 days. The 3rd satellite will be launched directly into a geostationary transfer orbit.
Geostationary Transfer OrbitLuna 26 (also named Luna-Resurs) is a planned lunar polar orbiter, part of the Luna-Glob program, by the Russian space agency Roscosmos. In addition to its scientific role, the Luna 26 orbiter would also function as a telecommunication relay between Earth and Russian landed assets. The scientific payload on board the orbiter is composed of fourteen instruments that will be fabricated by Russia. The payload will study the lunar surface and the environment around the Moon, including the solar wind, and high-energy cosmic rays. Luna 26 will also scout sites for the planned Luna 27 landing mission. Luna 26 is the second mission of Russia's new lunar program, which includes the launch of Luna 27, a heavy lander that will study the composition of the lunar soil by collecting several samples. Luna 28, a lunar samples return mission, will be the first to return samples at lunar temperature, and will serve as a demonstration for a future Martian samples return mission. Finally, Luna 29 should land a heavy lunar rover on the surface.
Lunar OrbitThor 8 is a multi-purpose communications satellite for Space Norway. The satellite will both replace older satellites being phased out in the coming years and provide increased capacity and service offerings that offers capacity for both data services and broadcasting, such as high power direct-to-home (DTH) television services, from the 1° West orbital position. It carries two dedicated payloads for broadcasting in Europe and the Nordics, as well as payloads for data services to commercial and governmental customers. With a launch mass of 4 metric tons, the satellite will be built on Thales Alenia Space’s Spacebus-4000B2 platform and will operate in the Ka and Ku frequency bands.
