The orbiting science laboratory begins a series of marathon passes this week that favor the northern hemisphere.
The European Space Agency is opting to send its first rover to the Red Planet two years later than originally planned.
Russia's Mikhailo Lomonosov observatory takes to the skies on the hunt for gamma-ray bursts, cosmic rays, and near-Earth asteroids.
The Japanese space agency JAXA has released a timeline covering the Hitomi space observatory's failure last month. Salvage efforts continue but recovery appears unlikely.
The Kepler team unexpectedly found the planet-hunting spacecraft in emergency mode on April 7th, but with the spacecraft recovered, hopes are high that its newest search, this time for rogue planets, is still on. Read on to see how amateur observations can help!
Yuri Milner commits $100 million to Breakthrough Starshot, a research and development project toward sending interstellar nanoprobes to Alpha Centauri.
Ground controllers are scrambling to recover the Hitomi satellite from a mysterious 'debris anomaly' over the past weekend.
Observations by NASA's New Horizons spacecraft, combined with new modeling of long-term trends, suggest that Pluto's atmosphere is far more dynamic than anyone imagined.
By tracking deviations in spacecraft orbits, planetary scientists have created a high-resolution map of the Red Planet's gravitational pull.
The launch of ESA's ExoMars Trace Gas Orbiter and Schiaparelli lander heralds a new phase of Mars exploration.
An innovative CubeSat mission, slated to take to space this year, will demonstrate the feasibility of free-flying satellites.
Among its other geologic oddities, Pluto has clusters of hills floating in a frozen "sea" dominated by nitrogen ice. These bobbing bumps might hold clues to the plain's depth and evolution.
The Lunar Reconnaissance Orbiter has finally spotted the impact of the Apollo 16 booster, more than 43 years after it happened.
The U.S. Postal Service has unveiled new stamps, to be issued later this year, that feature 10 solar-system objects — including Pluto.
An innovative and tiny thruster design could prove the future of interplanetary exploration with the tiny satellites known as CubeSats.
Are enigmatic gullies seen on many steep Martian slopes caused by liquid water or instead by episodic coatings of frozen carbon dioxide?
A mechanical problem in the spacecraft's seismometer can't be fixed before the planned launch date, so NASA managers have postponed the mission until 2018.
Scientists and engineers gathered together to figure out what would make a good Martian landing site and what hurdles they’ll have to overcome for a 2035 launch.
China's recently launched Dark Matter Particle Explorer (DAMPE) takes the hunt for elusive dark matter to space.
Following a wildly popular contest, the International Astronomical Union has named 14 stars and 31 planets that orbit them.
Results from NASA's Dawn spacecraft hint that the stark brightenings in and near scores of craters on Ceres might result from salty brines seeping onto the surface.
Engineers executed an innovative contingency plan to save the Akatsuki spacecraft and place it in orbit around our sister planet.
An exciting new mission takes the hunt for gravitational waves into space.
As ESA's comet orbiter enters its final year of operations, mission managers are deciding its fate.
Four months after New Horizons' historic flyby, mission scientists have been amazed by unexpected discoveries — and by how some preconceptions about Pluto were flat-out wrong.
