Die ESA-Ausschreibung für die M8/F3-Mission scheint sehr populär zu sein - hier mal eine (vorläufige) Aufstellung der Vorschläge, die in der Phase-1 eingereicht wurden:
für die M8-Mission: ARAGO – A mission to take stellar spectra and their polarization in VIS and UV.
newASTROGAM – A Gamma ray observatory mostly in the MeV range.
CALICO+ - A mission to land in Occator Crater on Ceres to sample the surface.
FOSSIL – A high resolution spectrometer to measure spectral distortions in the CMB.
GUEST – Gravitational Universe Exploration with Satellite Tracking
HAYDN – An astroseismology mission.
Heavy Metal – A mission to characterize the large M-class asteroid (216) Kleopatra and its two moons.
INANNA
Low Thermosphere-Ionosphere Mission
ORIGO – A mission to measure pristine cometary material in situ.
PHEMTO – A hard X-ray observatory in the 1-600 keV range.
PRIAMOS - A mission proposal to return a sample from a D-type NEO to Earth.
SHARP – A space based radio observatory in the 0.3 − 30MHz range.
SPARK - The mission aims to investigate solar particle acceleration and the magnetic energy release that powers it.
STE-QUEST – An atomic interferometer to test several fundamental principals in physics.
STEIN: Satellite Test of EINstein's gravitation theory
THEIA – An ultra-high precision relative astrometry mission.
Theon – A 2m telescope for high resolution spectroscopy in the UV and VIS. Might include a starshade called Theon*.
für die F3-Mission: ARCO - Astrophysics of Relativistic Compact Objects
DUNGEY-V – A multiple flyby mission to study the magnetotail of Venus.
ECLIPSE – A mission to deploy a seismometer on the lunar surface. (also proposed as mini-F)
GRINTA – A hard X-ray imager to rapidly follow up GRBs.
MESOM - A mission to study the sun's corona using the moon as a coronograph every 30 days.
MESSIER Surveyor – A UV-VIS survey to test the ΛCDM paradigm of structure formation.
PROMETHEUS – A spectrograph in the NUV – VIS range to measure the composition and age of stars.
VATMOS-SR - Venus Atmospheric Sample Return mission, name speaks for itself
VIVA – A mission to reveal interior structure, thermosphere dynamics and meteoroid flux from atmospheric response to seismic waves, volcanic events etc.
Mini-F-Vorschläge: ECLIPSE – A mission to deploy a three-axis seismometer on the lunar surface. (also proposed as F3)
Hannes
Temple Tuttle Leonid Flash-sat
VERVE – A 6-8U cubesat with a submillimetre spectrometer scanning Venus for out-of-equilibrium gases, riding piggyback with ENVISION.
unklar, ob M8- oder F3-Vorschläge: C4life – A mid-infrared space interferometer to investigate the carbon content in protoplanetary discs.
CoSI: Comet Surface Interaction Mission
EXPO – The Enhanced X-ray Polarimetry Observatory, maybe a variation of XIPE
GUEST: Gravitational Universe Exploration with Satellite Tracking
LETO - Line Emission Terahertz Observatory
LOT: The Lunar Optical Telescope
M-EUSO: Multi-messenger Extreme Universe Space Observatory
PALLAS INTERSTELLAR – Probably a mission to the mainbelt asteroid Pallas.
TriAS - A mission to a Triple Near-Earth Asteroid System.
