In the last century, Russia and the United States engaged competitively in both a space race and a nuclear technology race. In this century, it appears the two are considering collaborating.
...a big announcement today. Indeed, that announcement is big: about 22 stories big. SpaceX founder Elon Musk today unveiled the company’s next big thing, the Falcon Heavy rocket, a massive launch vehicle with a cargo capacity of 117,000 pounds.
Near-Earth asteroids aren’t all that rare, but today two researchers at Armagh Observatory in Northern Ireland say they’ve found an extremely rare near-Earth object in an orbit very similar to Earth’s.
The unusual Comet Elenin is expected to pass within 21 million miles of Earth on October 16, 2011 and speeding by at more than 85,000 mph—so fast it could travel from Earth to the Moon in less than five hours. Discovered by amateur Russian astronomer
They may not actually be driving on the moon, but 84 teams from the United States and three other countries are hoping they've got the right stuff to win NASA's latest rover race, a pedal-powered challenge to build the sleekest, fastest mock moonbugg
A photo may be worth 1,000 words, but a new depiction of NASA's Kepler mission is worth 1,235 potential alien planets. Created by a devoted mission scientist, the image takes stock of the Kepler observatory's prolific planet-hunting results so far.
A Japanese robot space cargo ship is carrying a device to "phone home" during its planned death plunge into Earth's atmosphere this week, but the equipment has a more important purpose than calling E.T. for help.
March 22, 2011, Centennial, CO, and Mojave, CA, USA: United Launch Alliance (ULA) and XCOR Aerospace announced today their successful hot-fire demonstrations of a lighter-weight, lower-cost approach to liquid-fueled rocket-engine vacuum nozzles. Th
A research institution that has inked landmark deals with two private spaceflight firms may be performing experiments in suborbital space within two years, one of its scientists says.
The space coach concept vehicle is water-driven with its solar-powered electrothermal engines. These engines would super-heat water, and the resulting steam would then be vented out of a nozzle, producing the necessary amount of thrust.
Mysterious caverns dotting the surface of Mars may harbor alien life. If life does exist there, Aron Kisdi, an engineer at the University of Southampton, U.K., thinks the fastest, cheapest way to find it is by sending in swarms of robots. While scien
The U.S. National Aeronautics and Space Administration (NASA) has revised its earlier estimates of Earthlike worlds in our galaxy. Now the space agency believes up to 2 billion such planets exist. Stating that about one of every 37 to 70 type-G stars
The center of the Milky Way is hard to see in visible light, because interstellar dust blocks our view. But the Spitzer Space Telescope’s infrared vision can penetrate the dust and see through to our galaxy’s jam-packed core.
The spacecraft is carrying high-res imaging equipment and an array of spectrometers which are amazingly kept at room temperature by its heat shields despite the proximity of the Sun. On March 23 these instruments will be switched on and tested befo
After a nearly 5-billion-mile journey that took more than six years, a NASA probe is finally ready to make history tonight (March 17) and become the first spacecraft ever to enter into orbit around the planet Mercury. At 8:45 p.m. EDT (0045 GMT F
Mercury is going so much faster than Earth that a spacecraft must gain about 65,000 mph to catch it. And once you get there, you're face to face with the searing heat of the sun."
New measurements of the expansion rate of the universe lend new support for the theory of dark energy that suggests a mysterious force is pulling the cosmos apart at ever-increasing speeds. Scientists have few ideas why such a force would exist, but
A new network of surveillance cameras will track meteorites as they enter Earth’s atmosphere, helping meteor-hunters track where the rocks land and where they came from.
NASA and its Russian counterpart inked a new $753 million modification to its current International Space Station transportation deal Monday, securing seats on the Russian Soyuz spacecraft from 2014 to 2016 at a price of almost $63 million per seat.
NASA’s intrepid Mercury observer, the Messenger satellite, is about to become the first spacecraft ever to orbit the first planet. The probe, which has already flown past the planet three times, will fire its thrusters March 17 so it can enter orbit
See the two sunspots beneath the puff? The little one, to the right, is twice the size of Earth.
With NASA’s space shuttle program in full wind-down, it seems like there are a lot of “lasts” in America’s storied, three-decade Space Transportation System.
A photograph taken through a scanning electron microscope of a CI1 meteorite is similar in size and overall structure to the giant bacterium Titanospirillum velox, an organism found here on planet Earth, a NASA scientist said.
The U.S. Air Force is poised to launch its second robotic X-37B space plane on a secret mission today (March 4), with some experts speculating that the classified flight will test new spy satellite technologies.
This is an image of the Space Shuttle Discovery taken from the ground, no easy feat in itself. But it wasn’t taken by an observatory or a massive scientific instrument.
Two companies promising routine suborbital access have signed the first-ever contracts to ferry researchers beyond the Earth’s limb and into space.
No 'mass exodus,' but hard choices ahead for U.S. astronaut corps
It's something the ancient Greeks could have only wished for: the Olympic torch being carried to the gods in Olympus and being lit by Apollo, the sun god. Now, Russia may fulfill the Greek's ultimate Olympic dream. Vitaly Davydov, deputy head of Ru
Pancake-layers and a possible powdery flow are among the surface features of interest highlighted in this July 4, 2005, Deep Impact photo of Comet Tempel 1. The bright flash is where Deep Impact dropped an 820 lb copper projectile onto the comet. Sta
NASA’s space shuttle Discovery is queued up for its final mission Thursday Feb. 24 at 4:50 p.m. Eastern time, but you don’t need to race to the Space Coast to catch the action.
