The Pioneers or Astrophysics Pioneers Program is a NASA program started in 2020 intended to use small-size hardware. The missions are expected to include SmallSats , Balloon payloads, and payloads attached to the ISS , with a $20M cost cap.
The craft are further grouped by mission status – "en-route", "mission in progress" or "mission complete" – based on their primary mission. For example, though Voyager 1 is still contactable en-route to the Oort Cloud and has exited the Solar System , it is listed as "mission complete" because its primary task of studying Jupiter and Saturn ...
The mission will include an orbiter, a relay satellite, a lander, a rover, and a mini-flying probe. [ 3 ] China also plans to launch Xuntian , a large space telescope that will co-orbit with the Tiangong space station , in 2026.
The James Webb Space Telescope launched in December 2021. By the time it launched, JWST cost about US$10 billion. NASA's large strategic science missions or large strategic missions, formerly known as Flagship missions or Flagship-class missions, [1] [2] are the costliest and most capable NASA science spacecraft.

Dragonfly and CAESAR, a comet sample return mission to 67P/Churyumov–Gerasimenko, were the two finalists for the New Frontiers program Mission 4, [25] [26] and on 27 June 2019, NASA selected Dragonfly for development with a plan to launch in June 2027. [27] [28] On 3 March 2023, Dragonfly passed its preliminary design review (PDR). [29]
Athena completed successfully its Phase A with the Mission Formulation Review on 12 November 2019. The next key milestone will be the mission adoption by ESA's Science Programme Committee (SPC) expected in 2023 [needs update], leading to launch in 2035. [1] In 2023, the mission was rescoped as NewAthena, with launch date moved to 2037. [6]
The Compton Spectrometer and Imager (COSI) is a NASA SMEX astrophysics mission that will launch a soft gamma-ray telescope (0.2–5 MeV) in 2027. [2] [3] It is a wide-field compact Compton telescope (CCT) that is uniquely suited to investigate the "MeV gap" (0.1–10 MeV). [4]
