The chief designer of China's Mars exploration program has provided a long-awaited comment on the status of the country's Zhurong Mars rover.

This object is, in fact, a pair: a white dwarf star that steadily burns at a relatively cool temperature and a highly variable red giant.

NASA recently reported that several of its high-energy space observatories spotted another black hole tidal disruption event, and it happened in another galaxy.

Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.

Astronomers have directly measured the mass of a single, isolated white dwarf -- the surviving core of a burned-out, Sun-like star. Researchers found that the white dwarf is 56 percent the mass of our Sun.

The USSF-67 mission carried a military communications satellite and five smaller payloads to orbit.

The fifth day of the 25.5-day Artemis I mission, a camera mounted on the tip of one of Orion’s solar array wings captured this footage of the spacecraft and the Moon as it continued to grow nearer to our lunar neighbor.

While observing the outer region of the Milky Way galaxy, our Spitzer Telescope captured this infrared image of a cloud of gas and dust that looks like the hollowed-out pumpkins we see every Halloween.

The International Space Station captured a portion of the Tanggula Mountains near Hala Lake from 260 miles above on the Earth.

NASA’s Lucy spacecraft captured this image of the Earth and the Moon from 890,000 miles (1.4 million km) away.

During its 40th close pass by Jupiter, our Juno spacecraft saw Ganymede cast a large, dark spot on the planet.

Space Crystals LLC plans to crystallize client DNA in space and put those stable crystals on the surface of the moon via lunar landers. Space Crystals has booked payload space for its first such delivery on a lander mission, company representatives said.

During panel discussions at the Beyond Earth Symposium representatives of several of the companies working on commercial space stations said they have to deal with an “alphabet soup” of agencies, none of which today have the authority to provide oversight of their operations as required under the Outer Space Treaty.

The microwave oven-sized CAPSTONE is a pioneer in cubesat science, helping to expand the reach of these little spacecraft well beyond Earth orbit. The still-undiagnosed issues may demonstrate the challenge of operating smaller vehicles in the radiation-laden environment of deep space.

NASA and Axiom Space have signed a mission order for the second private astronaut mission to the International Space Station to take place in the second quarter of 2023.
