NASA publishes tantalizing close-ups of dwarf planet Ceres
Imagery from NASA's Dawn spacecraft, now in its closest orbit of the dwarf planet Ceres, reveal textures, landscapes and bright streaks possibly made of salts exposed by violent collisions with asteroids.
Hold-down firing completed ahead of Sunday’s Falcon 9 launch
SpaceX's launch team ran through a traditional preflight test Monday, putting a Falcon 9 rocket through a mock countdown, loading it with propellant and briefly firing its nine engines on a launch pad in California ahead of this weekend's liftoff with a U.S.-European oceanography satellite.
Offshore barge landing targeted after next Falcon 9 launch
Nearly a month after nailing a landing a rocket landing at Cape Canaveral, SpaceX plans to steer the next flight of a Falcon 9 booster toward a recovery vessel in the Pacific Ocean after a Jan. 17 blastoff from Vandenberg Air Force Base in California.
U.S. lab generates first space-grade plutonium sample since 1980s
For the first time in nearly 30 years, the U.S. Department of Energy has produced a sample of plutonium-238, the radioactive isotope used to power deep space missions, good news for future NASA space probes heading to destinations starved of sunlight.
Pluto’s floating mountains, intriguing structures fascinate scientists
Nearly six months after NASA's New Horizons probe zoomed past Pluto, just one quarter of the data stored on board has made its way back to waiting scientists, revealing a surprisingly varied terrain that includes glacial flows and steep mountains of frozen water floating in a "sea" of slush-like nitrogen ice.
ESA wants to be a part of NASA’s mission to Europa
As NASA quietly works on a lander that could accompany a $2 billion flyby probe to Jupiter's icy moon Europa, the head of the European Space Agency's science program tells Spaceflight Now that Europe is ready to play a significant role in the project.
European Mars probe arrives at launch site
Three heavy-duty Antonov cargo planes flew components of Europe's ExoMars orbiter and lander from Italy to the Baikonur Cosmodrome in Kazkhastan last week, setting up for a March 14 launch toward the red planet.
Launch of NASA’s next Mars mission delayed until at least 2018
Persistent problems with a seismometer instrument package will keep NASA's InSight Mars lander from departing for the red planet during a March launch period, and officials said they will consider shelving the $675 million project if the issues prove too costly to fix.
Saturn’s moons align for cosmic photo opportunity
NASA has released an image of Saturn's moons Enceladus and Tethys caught in a rare alignment by the Cassini spacecraft, which is heading for its final close encounter with the icy moon Enceladus Saturday.
Asteroid probe confirmed on good trajectory after Earth flyby
A Japanese space probe picked up just the right amount of speed when it flew by Earth earlier this month, using the planet's gravity to slingshot toward an asteroid scientists think is a primordial leftover from the ancient solar system, mission managers said Monday.
