Solar wind blasting away Martian atmosphere

November 5, 2015

The solar wind, the million-mile-per-hour stream of charged particles blasted away from the sun, is slowly but surely stripping away Mars’ atmosphere and likely played a major role in turning the red planet from a habitable world in the distant past into the dry, frozen wasteland seen today, scientists said Thursday.

Charon takes center stage in new batch of New Horizons images

October 2, 2015

With meandering canyons four times as long, and twice as deep, as the Grand Canyon in the American Southwest, the crust of Pluto’s moon Charon may have been shaped by violent eruptions and geology once thought improbable for a small body in the far depths of the solar system, scientists said Thursday.

Secrets behind Pluto’s pastels far from being answered

Geologists said Thursday they are bewildered by images from NASA’s New Horizons spacecraft baring unseen landscapes on Pluto with unexpected “snakeskin” textures, colorful chasms routing through ancient landforms, and vivid new views of apparent glacial flows.

Dawn gets better look at bright spots on Ceres

September 9, 2015

NASA’s Dawn spacecraft, nearly halfway through its exploration of the dwarf planet Ceres, has returned its best images yet of a mysterious grouping of bright spots inside a crater on the Texas-sized world, bolstering evidence that Ceres is geologically alive.

Uranus, Neptune in NASA’s sights for new robotic mission

August 25, 2015

NASA has asked scientists to assess how to design and fly robotic space probes to Uranus and Neptune, the last of the solar system’s classical planets yet to be orbited, likely ensuring the huge icy worlds are near the top of the space agency’s to-do list in the coming decades.

Dawn enters new orbit closer to Ceres

June 7, 2015

NASA’s Dawn asteroid explorer has arrived at its new perch 2,700 miles from the dwarf planet Ceres, a vantage point scientists say will yield better views as the probe continues to step closer to the surface.

Diverse destinations considered for new interplanetary probe

April 6, 2015

Science teams from across the United States have submitted 28 proposals for missions to explore the moons of Jupiter and Saturn, touch the asteroid-like satellites orbiting Mars, visit unseen worlds and hunt for objects that could strike Earth one day.

NASA receives proposals for new planetary science mission

February 24, 2015

The proposals are in for a new NASA mission for launch in 2021 to explore the solar system, and scientists have submitted concepts for probes to the moon, planets, asteroids and comets for a chance to win $450 million in federal funding.
