SOLAR-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 OrbitLuna 27 (also named Luna-Resurs 1) is a planned lunar lander mission by Roscosmos to send a lander to the South Pole–Aitken basin, an area on the far side of the Moon. The purpose is to prospect for minerals, volatiles (nitrogen, water, carbon dioxide, ammonia, hydrogen, methane and sulfur dioxide, and lunar water ice in permanently shadowed areas of the Moon and investigate the potential use of these natural lunar resources. On the long term, Russia considers building a crewed base on the Moon's far side that would bring scientific and commercial benefits. The lander will feature 15 science instruments that will analyse the regolith, plasma in the exosphere, dust, and seismic activity. The payload will include a sampling drill.
Lunar OrbitTwo satellites for the Norwegian Space Agency’s Arctic Ocean Surveillance (AOS) program. AOS-Demo will be built by thr Norwegian engineering company Eidel to demonstrate maritime monitoring technologies. AOS-Precursor will be built by Kongsberg Defence & Aerospace as the first operational satellite of the system to track maritime activities in the Arctic.
Sun-Synchronous OrbitDESTINY+ (Demonstration and Experiment of Space Technology for INterplanetary voYage with Phaethon fLyby and dUst Science) is a planned asteroid exploration mission to 3200 Phaethon, the parent body of the Geminids meteor shower. It will demonstrate further improvements of low cost solar electric propulsion in deep space and innovative light-weight solar array panel technology. The spacecraft will carry 3 science instruments: * DESTINY Dust Analyzer (DDA) * Telescopic Camera for Phaethon (TCAP) * Multiband Camera for Phaethon (MCAP)
AsteroidAtmospheric Remote sensing Infrared Exoplanet Large survey mission (ARIEL) is an ESA telescope. During a 4-year mission, ARIEL will observe 1000 planets orbiting distant stars and make the first large-scale survey of the chemistry of exoplanet atmospheres. For a select number of exoplanets, ARIEL will also perform a deep survey of their cloud systems and study seasonal and daily atmospheric variations. ARIEL shares the ride with another ESA mission, Comet Interceptor. It 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.
