2030s in spaceflight

third large mission of Cosmic Vision; gravitational-wave space observatory

Venera-17 or Venera-D (, ) is a proposed Russian space mission to Venus that would include an orbiter and a lander to be launched in 2036. The orbiter's prime objective is to perform observations with the use of a radar. The lander, based on the Venera design, would be capable of operating for a long duration (≈3 h) on the planet's surface. The "D" in Venera-D stands for "долгоживущая" ("dolgozhivuschaya"), which means "long lasting" in Russian.

DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) is a planned mission for an orbiter and atmospheric probe to the planet Venus. Together with the separate VERITAS mission, which will also study Venus, it was selected by NASA on June 2, 2021, to be part of their Discovery Program. Its acronym is inspired by Leonardo da Vinci in honor of his scientific innovations, aerial sketches and constructions.

proposed spacecraft mission to Venus

EnVision is an orbital mission to Venus being developed by the European Space Agency (ESA) that is planned to perform high-resolution radar mapping and atmospheric studies. EnVision is designed to help scientists understand the relationships between its geological activity and the atmosphere, and it will investigate why Venus and Earth took different evolutionary paths. The probe was selected as the fifth medium mission (M5) of ESA's Cosmic Vision programme in June 2021, with launch planned for December 2031. The mission will be conducted in collaboration with NASA.

The mission is aimed at observing at least 1,000 known exoplanets using the transit method, studying and characterising the planets' chemical composition and thermal structures. Compared to the James Webb Space Telescope, Ariel will be a much smaller telescope with more observing time available for planet characterisation. Ariel was expected to be launched in 2029 aboa

Spektr-UV, also known as World Space Observatory-Ultraviolet (WSO-UV), is a proposed ultraviolet space telescope intended for work in the 115 nm to 315 nm wavelength range. It is an international project led by Russia (Roscosmos), with participation from Spain and Japan. The launch had initially been planned for 2007, but has since been continually delayed; , the launch is expected to take place no earlier than 2031 atop an Angara A5M rocket from Vostochny Cosmodrome.

LiteBIRD (Lite (Light) satellite for the studies of B-mode polarization and Inflation from cosmic background Radiation Detection) is a planned small space observatory that aims to detect the footprint of the primordial gravitational wave on the cosmic microwave background (CMB) in a form of polarization pattern called B-mode.

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.
