NASA's Osiris-REX spacecraft launched successfully from Cape Canaveral on September 8th and is headed to asteroid Bennu for a dramatic sample return mission.
On August 27th, NASA's Juno made its closest pass to the giant planet — here's what we learned.
It's taken nearly two years, but a dedicated search of craggy Comet 67P/Churyumov-Gerasimenko has turned up the long-lost landing craft Philae.
Dust and gas between stars would pose a threat to spacecraft en route from Earth to the Alpha Centauri system — and scientists are seriously considering the problem now that the prospect of interstellar travel is no longer sci-fi.
The discovery of trans-Neptunian object 2011 KT19 in a strange orbit deepens a key mystery in the outer solar system.
Careful tracking of NASA's Dawn spacecraft reveals that Ceres has a rocky core and a thick ice-and-salt crust. Maybe a briny ocean still lies buried inside.
JAXA and NASA are looking at the possibility of replacing the dead Hitomi X-ray observatory, with a potential launch around 2020.
The Mars 2020 rover reached a third crucial milestone this past week on the path to the launch pad.
After a 5-year-long journey, NASA's latest emissary to the largest planet in the solar system has arrived at its destination.

Planetary scientists are counting on amateur observations to enhance the results from NASA's forthcoming Juno mission.
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!
