eROSITA is an X-ray instrument built by the Max Planck Institute for Extraterrestrial Physics (MPE) in Germany. It is part of the Russian–German Spektr-RG space observatory, which also carries the Russian telescope ART-XC. It was launched by Roscosmos on 13 July 2019 from Baikonur, and deployed in a 6-month halo orbit around the second Lagrange point (L2). It began collecting data in October 2019. Due to the breakdown of institutional cooperation between Germany and Russia after the invasion of Ukraine, the instrument stopped collecting data on February 26, 2022.

PEGASE is a design for a space observatory developed by France in the early 2000s. It combined formation flying with infrared telescopes operating as a double-aperture interferometer. Three free-flying satellites would operate together;a beam combiner and two siderostats. The baseline of the interferometer would be adjustable to between 50 and 500 meters. The goal of the mission is the study of Hot Jupiters ("pegasids"), brown dwarfs and the interior of protoplanetary disks. The design was developed by Centre National d'Études Spatiales and was studied for a launch as early as 2010–2012. Howev

JunoCam (or JCM) is the visible-light camera/telescope onboard NASA's Juno spacecraft that entered orbit around Jupiter in 2016. The camera is operated by the JunoCam Digital Electronics Assembly (JDEA). Both the camera and JDEA were built by Malin Space Science Systems. JunoCam takes a swath of imaging as the spacecraft rotates; the camera is fixed to the spacecraft, so as it rotates, it gets one sweep of observation. It has a field of view of 58 degrees with four filters (3 for visible light).

TUGSAT-1, also known as BRITE-Austria and CanX-3B, is the first Austrian satellite. It is an optical astronomy spacecraft operated by the Graz University of Technology as part of the international BRIght-star Target Explorer programme.

proposed space observatory to characterize exoplanets' atmospheres and their discovery.

The Extreme Universe Space Observatory onboard Japanese Experiment Module (JEM-EUSO) is the first space mission concept devoted to the investigation of cosmic rays and neutrinos of extreme energy (). Using the Earth's atmosphere as a giant detector, the detection is performed by looking at the streak of fluorescence produced when such a particle interacts with the Earth's atmosphere.

The STSat-1 (Science and Technology Satellite-1), formerly known as KAISTSat-4 (Korea Advanced Institute of Science and Technology Satellite-4), is an ultraviolet telescope in a satellite. It is funded by the Korea Aerospace Research Institute (KARI), and was launched on 27 September 2003, from Plesetsk Cosmodrome by a Kosmos-3M launch vehicle, into an Earth orbit with a height between 675 and 695 km.

The Exoplanet Characterisation Observatory (EChO) was a proposed space telescope as part of the Cosmic Vision roadmap of the European Space Agency, and competed with four other missions for the M3 slot in the programme. On 19 February 2014 the PLATO mission was selected in place of the other candidates in the programme, including EChO.

The Nano-Japan Astrometry Satellite Mission for Infrared Exploration (Nano-JASMINE) is an astrometric microsatellite developed by the National Astronomical Observatory of Japan, with contributions by the University of Tokyo's Intelligent Space Systems Laboratory (ISSL). , the satellite was planned for launch together with CHEOPS (Characterizing Exoplanets Satellite) in 2019. However, this launch took place in December 2019 without Nano-JASMINE as one of the three piggyback payloads. Some sources named 2022 as the launch year of the satellite. By 2023, the launch had been cancelled and the sate

Transient High-Energy Sky and Early Universe Surveyor (THESEUS) is a space telescope mission proposal by the European Space Agency that would study gamma-ray bursts and X-rays for investigating the early universe. If developed, the mission would investigate star formation rates and metallicity evolution, as well as studying the sources and physics of reionization.

RELIKT-1 from (sometimes RELICT-1) was a Soviet cosmic microwave background anisotropy experiment launched on board the Prognoz 9 satellite on 1 July 1983. It operated until February 1984. It was the first CMB satellite (followed by the Cosmic Background Explorer in 1989) and measured the CMB dipole, the Galactic plane, and gave upper limits on the quadrupole moment.
