One year ago today, LightSail 1 rode an Atlas V rocket into space. Now, the program stands on the brink of another major milestone, as engineers prepare for a full systems test of LightSail 2, a successor CubeSat that will attempt the first controlled solar sail flight in low-Earth orbit.
Japan's Akatsuki Venus orbiter is well into its science mission, and has already produced surprising science results. The mission, originally planned to last two years, could last as many as five, monitoring Venus' atmosphere over the long term.
Lockheed Martin proposed a system to send humans to orbit Mars in the year 2028—a concept that shares many core values with The Planetary Society's report, Humans Orbiting Mars, we released last year.
Astrophotographer Adam Block shares his latest image, this time of a menacing spiral galaxy.
The European Space Agency and Roskosmos have admitted the inevitable—the launch of the joint ExoMars-2018 project will have to be postponed for two years to 2020.
Two-and-a-half days after a dramatic sea rescue, the tugboat crew hauling a space shuttle fuel tank to California bid farewell to some unexpected passengers last night in San Diego.
The crew of the tugboat hauling the last unflown space shuttle external fuel tank to California reports they have rescued four passengers from a fishing boat that sunk off the coast of Mexico.
Opportunity arrived at its current location on sol 4345 to begin investigation of an outcrop on the crest of a ridge near the west end of Marathon Valley.
Looking back at Earth from beyond helps to give perspective on our place in the cosmos.
Anna Scott gets us up to speed on Earth-observing missions nearly 60 years into the satellite age.
Last week, the Rosetta mission released a large quantity of science data to the worldwide public, including photos from the mission's close observation phase and the Philae landing.
Opportunity and the Mars Exploration Rovers (MER) team pressed on through the Martian winter and spent April sleuthing for clay minerals at the mission’s new site on the southern wall of Marathon Valley.
The RS-25 powered the space shuttle for three decades, and will soon be used on the Space Launch System. Is it still the Ferrari of rocket engines? A deep dive on performance, reliability and the politics of rocket science.
A team of scientists at the University of Arizona continue their efforts to extract data from more than 90,000 images captured during NASA's Surveyor program. In the meantime, new first-look images and an animation have been release...
Why do we need to slice up atmospheres into classifications like the troposphere, stratosphere, mesosphere, and thermosphere?
Since April 11, instead of photographing the scenery directly beneath it, Dawn has been aiming its camera to the left and forward as it orbits and Ceres rotates to map more of the dwarf planet.
Justin Cowart shares some spectacular images showcasing Mars' volcanoes from Mars Express.
May 2016 will be yet another month of fairly routine operations across the solar system -- if you can ever use the word "routine" to describe autonomous robots exploring other planets. ExoMars' cruise to Mars has started smoothly, and Juno is only two months away from Jupiter orbit insertion. Earthlings will witness a Mercury transit of the Sun on May 9.
The solar system beyond Neptune is full of worlds hosting moons. Now we know that the dwarf planet Makemake has one of its very own.
HiRISE Principal Investigator Alfred McEwen explains an imaging technique known as Super-Resolution Restoration (SRR), and how it could come in handy for high-resolution imaging of the Red Planet.
