Europa’s surface is almost too clean for an icy moon bombarded for billions of years, and its missing scars point to a young crust repeatedly rewritten from below as NASA’s Europa Clipper heads to test whether Jupiter’s tides keep a hidden ocean alive

NASA’s Europa Clipper mission is heading toward one of the most revealing puzzles in the outer Solar System. Jupiter’s icy moon Europa has so few large impact craters that scientists think its surface has been repeatedly renewed from below, according to the mission’s Europa Clipper page. That clean ice may be the visible sign of…

In 1970, Venera 7 survived 23 minutes on Venus in 475-degree heat and crushing 90-atmosphere pressure, sent the first data from another planet’s surface, and engineers only realized weeks later that the faint signal had continued after landing while the probe’s titanium hardware may still be recognizable today

Mars may have kept rivers, long-lived lakes and possibly a northern ocean for hundreds of millions of years, giving the Red Planet a wet window that rivals the age of complex animal life on Earth

When Sergei Krikalev launched from Baikonur in May 1991, he was a Soviet cosmonaut bound for Mir, but when he returned 311 days later the Soviet Union had dissolved, Leningrad had become St. Petersburg and his spacesuit still carried the USSR letters and red flag from a country that had disappeared beneath him while Mir kept circling Earth

NASA’s Roman Space Telescope reaches Kennedy ahead of schedule as Aug. 30 Falcon Heavy launch preparations begin

NASA’s official Roman mission announcement marks a major step toward launch for the agency’s next great space observatory. The NASA’s Nancy Grace Roman Space Telescope arrived at Kennedy Space Center in Florida on June 21, 2026, starting its final round of launch preparations before a targeted liftoff no earlier than Aug. 30. The spacecraft is…

Russian cosmonaut Sergei Krikalev spent 803 days in orbit and became about 0.02 seconds younger, turning Einstein’s time dilation into a measurable human spaceflight record

803 days in orbit, according to the World Air Sports Federation’s official record announcement, gave Russian cosmonaut Sergei Krikalev a tiny but real place in the physics of time. During six spaceflights, his high-speed travel around Earth made his onboard clock lag behind clocks on the ground by about 0.02 seconds. That fraction sounds almost…

Webb finds a lemon-shaped planet circling a pulsar, with a carbon atmosphere unlike any seen before and a formation story astronomers still can’t explain

NASA’s Webb announcement reports that astronomers used the James Webb Space Telescope to watch PSR J2322-2650b through a full orbit around a pulsar. The result is a strange world with a carbon-rich atmosphere, a stretched shape and a history that current formation ideas struggle to explain. The planet has roughly the mass of Jupiter and…
