After more than a year of delays, the Antares rocket was rolled out onto its Virginia coast launch pad on Saturday in preparation for the first of two test launches, the first of which is scheduled for April 17. Should everything go according to plan, the rocket, developed by aerospace firm Orbital Sciences Corp., will work ferrying cargo to the International Space Station (ISS) as part of a $1.9 billion deal with NASA.
Using ratios of the element argon, scientists believe they have finally confirmed that Mars once has an atmosphere that has gradually been slipping away.
Scientists have identified the age of the meteorite thought to be from Mercury and it's not looking good - the rock is estimated to be 4.5 billion years old, which, some scientists believe, is too old.
NASA announced Friday two new projects headed for a 2017 launch, one of which, the Transiting Exoplanet Survey Satellite (TESS), will cover an estimated 400 times as much sky as any previous as it locates planets orbiting nearby stars. Led by George Ricker of the Massachusetts Institute of Technology (MIT), scientists plan to focus the spacecraft's efforts on examining planets similar to the habitable zones of their host stars and specifically those similar in size to Earth.
NASA announced Friday that it would begin funding an explorer that would help to unveil the many mysteries of the little-understood phenomenon called the neutron star.
Astronomers at NASA have spotted the most distant supernova yet; in fact, the event took place so far away that as scientists watched it, they were watching an event that took place 10 billion years ago. Nicknamed SN Wilson, the phenomenon was specifically classified Type 1a supernova and may offer scientists a sense of how the universe has expanded ever since the Big Bang.
NASA's new motto goes something like this: Without funding, anything is possible. Or maybe just the classic: Recycle, recycle, recycle. Either way, the agency is looking at turning the upper-stage propellant tank of the mega-rocket Space Launch System (SLS) into a permanently manned outpost in space.
The supersonic parachute that helped NASA's rover Curiosity land safely on Mars eight months has become the focal point of some recently released images from NASA.
For the first time scientists have located young stars with similar masses to our Sun located outside of the Milky Way. The location? The Small Magellanic Cloud.
After 46 years at the Goddard Institute for Space Studies, one of climate change's most vocal proponents, James E. Hansen, is quitting.
NASA's Mars rover Curiosity may have identified perchlorate in a sand patch within the Gale Crater. Perchlorates are a known energy source for some types of Earth-dwelling microbes.
Thirty-five green rocks found in Morocco last year may actually be the first known meteorite samples from Mercury the wold has ever seen.
Three men prepare to take off in what will be the fastest journey to the International Space Station yet.
Ever wanted to own an American flag that flew to the Moon? Now you can, thanks to a law passed by Congress enabling the sale of space memorabilia.
