    China just landed the first spacecraft on the moon's farside

    China’s Chang’e-4 lander and rover just became the first spacecraft to land on the farside of the moon.

    The lander touched down at 9:26 p.m. Eastern time on January 2, according to an announcement from the China National Space Administration. The spacecraft is part of a series of Chinese space missions named Chang’e (pronounced CHONG-uh) for the Chinese goddess of the moon.

    A small...

    New Horizons shows Ultima Thule looks like a snowman, or maybe BB-8

    The results are in: Ultima Thule, the distant Kuiper Belt object that got a close visit from the New Horizons spacecraft on New Year’s Day, looks like two balls stuck together.

    “What you are seeing is the first contact binary ever explored by a spacecraft, two separate objects that are now joined together,” principal investigator Alan Stern of the Southwest Research Institute in Boulder...

    The sugar that makes up DNA could be made in space

    Parts of DNA can form in space.

    For the first time, scientists have made 2-deoxyribose, the sugar that makes up the backbone of DNA, under cosmic conditions in the lab by blasting ice with radiation. The result, reported December 18 in Nature Communications, suggests that there are several ways for prebiotic chemistry to take place in space, and supports the idea that the stuff of life...

    New Horizons gears up for its close encounter with Ultima Thule

    Ultima Thule is one of the solar system’s most hermitlike homebodies. In the 4.6 billion years since the small icy world formed, astronomers think that it has never moved from its original orbit about 6.5 billion kilometers from the sun. And no other large object has ever come calling.

    That’s about to change.

    Just after midnight eastern time on January 1, NASA’s New Horizons...

    A buried lake on Mars excited and baffled scientists

    Headlines touting the discovery of water on Mars — again! — are a long-standing punchline among planetary scientists. But a discovery this year was something very different.

    Unlike previous claims of water-bearing rocks or ephemeral streaks of brine, researchers reported in the Aug. 3 Science that they had found a wide lake of standing liquid near the Red Planet’s south pole, buried...

    NASA’s OSIRIS-REx finds signs of water on the asteroid Bennu

    As the asteroid Bennu comes into sharper focus, planetary scientists are seeing signs of water locked up in the asteroid’s rocks, NASA team members announced December 10.

    “It’s one of the things we were hoping to find,” team member Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Md., said in a news conference at the American Geophysical Union meeting in Washington, D.C. “...

    NASA’s OSIRIS-REx spacecraft has finally arrived at asteroid Bennu

    A spacecraft designed to pick up pieces of an asteroid and bring them back to Earth has finally reached its destination. After a two-year journey, NASA’s OSIRIS-REx spacecraft caught up with asteroid Bennu, currently located nearly 130 million kilometers from Earth, on December 3.

    “We have arrived!” Javier Cerna, a telecommunications systems engineer with aerospace and defense company...

    NASA’s InSight lander has touched down safely on Mars

    Editor’s note: This story will be periodically updated as new images are released.

    NASA’s InSight lander touched down on Mars on November 26 for a study of the Red Planet’s insides.

    “Touchdown confirmed, InSight is on the surface of Mars!” said Christine Szalai, a spacecraft engineer at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., in a live broadcast from mission control....

    An orbiter glitch may mean some signs of liquid water on Mars aren’t real

    Some signs of water on Mars may have just dried up.

    Thanks to the way data from NASA’s Mars Reconnaissance Orbiter are handled, the spacecraft may be seeing signs of hydrated salts that aren’t really there, planetary scientists report online November 9 in Geophysical Research Letters.

    That lack of salts could mean that certain sites proposed as places where life could exist on Mars...
