The private spaceflight company Virgin Galactic will soon begin a new round of rocket-powered test flights of the commercial spaceliner SpaceShipTwo to prepare for eventual passenger flights to space.
The discovery of extraterrestrial beings — be they slimy microbes or little green men — would dramatically change the way we humans view our place in the universe. But would it shatter religion?
Jet Propulsion Laboratory (JPL) in Pasadena, Calif., has selected proposals from 10 universities to begin investigating the possible use of cubesats as auxiliary components to missions to Europa and beyond.
I'd always wanted to visit Mars. Instead I got Hawaii. There, about 8,200 feet above sea level on Mauna Loa, sits a geodesically domed habitat for testing crew psychology and technologies for boldly going.
The high point of the Centennial Celebration is the Symposium featuring illustrious names in aerospace reflecting on past achievement, celebrating today's innovative research and education, and offering their perspectives on what lies ahead. Closin
Human hibernation could be a great way to get to Mars (and beyond), but a few big questions remain.
A space elevator is essentially a cable anchored to the Earth's equator and attached to a counterweight somewhere way above Earth's atmosphere — much higher than satellites in orbit.
A new vehicle design could enable same-day shipping from the ISS to Earth, making science experiments in microgravity cheaper and easier.
The European Space Agency's Rosetta spacecraft has sent home several spectacular images that show a large pyramid-shaped boulder studding the surface of its target comet.
A Lab-Made Black Hole May Confirm The Existence Of Exotic Radiation Predicted By Stephen Hawking 40 Years Ago.
A space elevator is essentially a cable anchored to the Earth's equator and attached to a counterweight somewhere way above Earth's atmosphere — much higher than satellites in orbit.
The U.S. Air Force's mysterious X-37B space plane will return to Earth this week —possibly as early as Tuesday — after 22 months in orbit on a secret mission.
But CEO Bas Lansdorp says the study used bad data.
Space exploration has many challenges, but one inconvenient fact in particular – the lack of oxygen in much of the universe – poses a real challenge to making offworld exploration and living a reality.
Space Exploration Technologies, the Elon Musk-owned company better known as SpaceX, has been heavily recruiting engineers from Microsoft and other companies in the region as it gears up a new Seattle-area office.
A privately built inflatable room for astronauts on the International Space Station is on track to launch into orbit next year.
SpaceX founder Elon Musk told Management Today recently: "I like Richard and I think he's doing some cool things. But technology is not really his whack you know. But once the technology's developed in terms of operating it in a way that people rea
Virgin Galactic's suborbital space plane took to the skies again Tuesday (Oct. 7), just three days after a big anniversary celebration for the vehicle's predecessor.
Last month, the US MAVEN space probe and the Indian MOM orbiter arrived at the planet Mars within days of one another.
A NASA-backed study explores an innovative way to dramatically cut the cost of a human expedition to Mars -- put the crew in stasis.
This is part of a Space.com series of articles on the Most Amazing Flying Machines Ever, the balloons, airplanes, rockets and more that got humans off the ground and into space.
Earth's atmosphere wasn't always full of life-giving oxygen — it was once a choking mixture of carbon dioxide and other gases, more like the atmosphere of Mars or Venus.
Ten years ago today, a former Navy pilot climbed into a homebuilt spaceship, was carried to a high altitude by a mothership in the skies over Mojave, California, dropped into free fall, and fired the spaceship's hybrid rocket motor to blast out of
Ten years ago Saturday (Oct. 4), the era of commercial spaceflight really started taking off.
The Vessel-ID System investigation on ISS tracks the Automatic Identification System (AIS) signal that is emitted from sea-faring ships on Earth. It relays ship position reports to tracking stations on the ground.
In November 2004, Popular Science profiled the Tier One team as they prepared to launch the commercial spaceflight industry.
Hayabusa 2 could be the first to intercept and blast an asteroid.
You don't have to become an astronaut to use the International Space Station's new 3D printer.
About three hours into Startup Weekend: Space, I seriously wondered what I had gotten myself into.
Ever since the historic achievement of August 6, when Rosetta became the first unmanned spacecraft to achieve a stable orbit around a comet, mission operators have been readying themselves for the inevitable nail-biting landing attempt.
