ESA's Comet Interceptor consists of three spacecraft which will be positioned at the Sun-Earth Lagrange point L2, where they will wait for a long-period comet or an interstellar object to come by. Once the desired target appears, the spacecraft will separate and perform a flyby of the target, compiling a detailed 3D profile of a comet.
Heliocentric N/AExoMars 2028 is a second mission of two-part European Space Agency astrobiology project to search for evidence of life on Mars. The primary objective is to land the rover at a site with high potential for finding well-preserved organic material, particularly from the very early history of the planet. The rover is expected to travel several kilometers during its mission. The European rover will be the first mission to combine the capability to move across the surface and to study Mars at depth. It will collect samples with a drill down to a depth of 2 m and analyze them with next-generation instruments in an onboard laboratory. Underground samples are more likely to include biomarkers, since the tenuous martian atmosphere offers little protection from radiation and photochemistry at the surface.
Heliocentric N/ASOLAR-C is a Japan-led international mission with the cooperation by the US and European countries. It aims to gain new insights into the fundamental physical mechanisms driving solar plasma dynamics by performing three simultaneous UV observations. The first consists to observe the broad range of temperatures, spanning over three orders of magnitude from the 10,000 Kelvin chromosphere to the million Kelvin corona, and even to the 15 million Kelvin solar flares. The second consists to resolve the elemental structures at high spatial (0.4 arcsec) and temporal (1 sec) resolution and trace their evolutions by increasing the ability to collect the solar UV rays 10 to 30 times as much as before. The third consists to conduct a high dispersion spectroscopy (equivalent to a velocity resolution of 2 km/s) to obtain spectroscopic information that enables quantitative diagnostics (such as velocity, temperature, density, ionization degree, and abundance). By combining the three observations, SOLAR-C can analyze the dynamically evolving solar atmospheres over a wide altitude range from the chromosphere to the corona while resolving elemental structures.
Sun-Synchronous Orbitispace Mission 3 will be the first mission to feature ispace’s new ULTRA lunar lander, a larger and more capable lander design than the HAKUTO-R that attempted to land on the Moon twice before. The lander will carry payloads for Science Tokyo, TASA, ispace, UEL, JALUX and Magna Petra Corp.
Lunar OrbitIntelsat 45 is a small geostationary communications satellite that will provide Ku-band fixed-satellite services enabling Intelsat to provide specialized and efficient service to Media and Network customers. IS-45 weighs about 1 metric ton at launch and is designed and built by SWISSto12, based on the company’s innovative HummingSat platform. HummingSats are just over one cubic meter in volume, one-tenth the size of conventional satellites placed in geostationary orbit. SWISSto12 is developing the satellites in collaboration with the European Space Agency (ESA) through its public-private-partnership program, benefiting from unique and patented 3D printing technologies.
