Current Missions
A Legacy of DiscoveryA Future of Innovation
NASA’s Astrophysics missions explore the full spectrum of the cosmos—from infrared to visible light to X-rays and beyond—revealing the fundamental nature of the universe and our place within it. These missions represent the United States’ enduring leadership in space science and technologycarrying forward a legacy of discovery that began with the Great Observatories.
Today’s active missions include icons such as the Hubble Space Telescopewhich continues to redefine our understanding of the universe more than three decades after launch; the Chandra X-ray Observatorywhich explores the high-energy universe through the study of black holesneutron starsand cosmic explosions; and the James Webb Space Telescope (JWST)which observes the universe in near-and mid-infrared light to reveal the first galaxies and the atmospheres of distant worlds.
Complementing these observatoriesthe Fermi Gamma-ray Space TelescopeNeil Gehrels Swift ObservatoryNuSTARNICERand IXPE open new windows on the most energetic processes in the cosmosfrom gamma-ray bursts to the remnants of stellar death.
Meanwhilethe Transiting Exoplanet Survey Satellite (TESS) surveys the sky in visible lightusing precise measurements to discover planets orbiting nearby stars. The recently launched SPHEREx mission extends NASA’s reach across optical and near-infrared wavelengthsmapping the entire sky to trace the history of galaxies and the building blocks of life throughout the cosmos.
Togetherthese observatories deliver an unparalleled view of the universe—advancing both science and the technologies that power American innovation.
NASA’s Astrophysics Division also supports U.S. participation in key international missionsincluding ESA’s XMM-Newton and Euclid missionsand JAXA’s XRISM mission. These collaborations leverage American technology and scientific expertise to expand humanity’s reach into the universe while strengthening trusted partnerships around the globe.
Each mission builds upon decades of U.S. investment and ingenuity—turning bold ideas into discovery and keeping the nation at the forefront of space exploration. The overall strategy for NASA astrophysics is driven by decadal surveysa task that is requested by Congress and carried out by the National Academy of Sciences.
The Future of Astrophysics
Building on DiscoveryShaping What Comes Next
NASA’s Astrophysics Division is entering a bold new eraguided by the discoveries of todaythe lessons learned from the pastand the visionary goals of tomorrow. The next generation of missions will expand humanity’s view of the cosmosharness emerging technologiesand ensure continued U.S. leadership in space science.
Launching in fall 2026the Nancy Grace Roman Space Telescope will open an unprecedented window into the universe. Roman will study dark energy and dark matterwhich together make up nearly 95% of the universeto uncover how these unseen forces shape cosmic evolution and drive the universe’s accelerating expansion. It will also identify thousands of new exoplanets beyond our solar system. By combining deep-field precision with a wide view of the sky and systematic surveys that track how stars and galaxies change with timeRoman will redefine how we explore the cosmos and our place within it. Roman will redefine how we explore the cosmos and our place within it.
Following Romanthe Compton Spectrometer and Imager (COSI)planned for launch in 2027will study how stars are born and dietracing the origins of chemical elements that make up planets and life itself.
Looking beyondNASA is developing the Habitable Worlds Observatory (HWO)the next major mission in our quest to understand the cosmos. Guided by the 2020 Decadal SurveyPathways to Discovery in Astronomy and Astrophysics for the 2020sHWO will build on the legacies of HubbleWebband Roman to search for Earth-like planets and signs of life beyond our solar system. It reflects a modern manifest destiny of the starsand a shared human journey to exploreto learnand to push the boundaries of what’s possible.
Going forwardthe Decadal Surveys will continue to provide the roadmap for the following decadeidentifying the highest-priority scientific questions and the technologies and missions needed to answer them.
