After almost three years on the Red Planet and 72 flights into the thin Martian atmosphere, NASA's Ingenuity Mars helicopter is ending its mission due to a broken rotor blade.

Seventy-two flights later, the small-but-mighty helicopter's time has come to an end after it was damaged during a test flight last week.

NASA astronaut Frank Rubio holds the record for the longest U.S. space flight, but he wasn't trying to earn that title.

Penzias, with his colleague Robert Woodrow Wilson, discovered the cosmic microwave background while working at Bell Labs in the 1960s. The finding was the smoking gun evidence for the Big Bang.

The lander was powered down at 12% battery power — saving enough juice for a potential restart. Now Japan's space agency will see if its solar cell can give the lander any electricity.

The helicopter had stopped communicating with the Perseverance rover during a test flight. Trouble for the overachieving rotorcraft threatened to cut short its otherworldly flight exploration.

Japan is now the fifth country to pull off a soft landing on the moon. A Japanese space agency manager earlier called the landing "a breathless, numbing 20 minutes of terror!"

The mission, Ax-3, is the third time Houston-based Axiom Space has sent paying passengers to the I.S.S. During 16 days of orbit, the all-European crew will conduct 30 experiments and public outreach.

Data from the James Webb Space Telescope indicate that a galaxy known as GN-z11 has a supermassive black hole at its center — one that's far more massive than astronomers expected.

The mission was to be the first time an American company sent a spacecraft to the moon — and the first time the U.S. returned to the lunar surface in more than 50 years.

The first U.S. moon landing attempt in more than 50 years appeared to be doomed after a private company's spacecraft developed a "critical" fuel leak just hours after Monday's launch.

A CEO of one of the companies offering "memorial spaceflights" says his customers view it as "an appropriate celebration" of their loved ones.

Neptune has long been depicted as a deeper, darker blue than its fellow ice giant Uranus, but a new study shows that both are a similar shade of light greenish blue.

The NASA spacecraft Juno captured the images during a flyby on Saturday. Scientists are hoping to learn more about Io, the most volcanic world in the solar system.

Our view of the constellations has changed since they were first mapped thousands of years ago. That new perspective could also mess with your astrological horoscope in the new year.
