    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...

    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...

    Readers react to the SN 10 and Jocelyn Bell Burnell

    Point, counterpoint

    In “The SN 10: These scientists defy limits to tackle big problems” (SN: 10/13/18, p. 18), Science News profiled 10 early- and mid-career scientists who are pushing boundaries to answer pressing questions facing science and society.

    Some readers had strong reactions to the profiles.

    Charles Eby praised stories about the SN 10 scientists. “Of course I love to...

    NASA’s Mars 2020 rover will look for ancient life in a former river delta

    The next NASA Mars rover will hunt for signs of ancient life in what used to be a river delta, the agency announced on November 19.

    The rover is expected to launch in July 2020 and to land on Mars around February 18, 2021. It will seek out signs of past life in the sediments and sands of Jezero crater, which was once home to a 250-meter-deep lake and a river delta that flowed into the...

    Tiny satellites will relay news of InSight’s Mars landing in minutes, not hours

    The next spacecraft set to land on Mars is bringing its own communications team. InSight, a lander scheduled to touch down on the Red Planet on November 26, is accompanied by a pair of briefcase-sized spacecraft that will send details of the landing to Earth in almost real time.

    The twin craft on this mission are CubeSats — tiny, inexpensive satellites that are easy to build and launch....

    Astronomers spot another star that flickers like Tabby’s star

    There’s another oddly flickering star in the galaxy.

    Astronomers using a telescope in Chile have discovered a star whose strange dimming and brightening of light are reminiscent of Tabby’s star, which was once suggested to host an alien megastructure.

    The megastructure idea, first posited in 2015, was later quashed by data suggesting that the dips are probably from dust particles...

    One of Earth’s shimmering dust clouds has been spotted at last

    Meet the Kordylewski dust clouds, shimmering pseudo-satellites that orbit Earth near the moon. A team of Hungarian astronomers say they have spotted light scattered from one of these clouds, providing evidence that the clouds really exist after nearly 60 years of controversy.

    The twin dust clouds gather at two of the points in space where the gravity of Earth and the moon cancel each...

    China is about to visit uncharted territory on the moon

    China is about to make space history. In December, the country will launch the first spacecraft ever to land on the farside of the moon. Another craft, slated for takeoff in 2019, will be the first to bring lunar rocks back to Earth since 1976.

    These two missions — the latest in China’s lunar exploration series named after the Chinese moon goddess, Chang’e — are at the forefront of...

    Hints of Oort clouds around other stars may lurk in the universe’s first light

    A thick sphere of icy debris known as the Oort cloud shrouds the solar system. Other star systems may harbor similar icy reservoirs, and those clouds may be visible in the universe’s oldest light, researchers report.

    Astronomer Eric Baxter of the University of Pennsylvania and colleagues looked for evidence of such exo-Oort clouds in maps of the cosmic microwave background, the cool...
