NASA releases 3D-printable models to the public

By - August 4, 2014 3 Pictures
If you have access to a 3D printer, then you can build your own space fleet courtesy of NASA – provided you don’t mind spacecraft that are plastic and four inches long. As part of its continuing program of education and outreach, the space agency has released 22 printable models of NASA and European space probes, asteroids, and planetary landscapes for the hobbyist and space enthusiast.

Rosetta spacecraft captures comet's developing coma

By - May 15, 2014 2 Pictures
On its way to rendezvous with comet 67P/Churyumov-Gerasimenko (67P, for short), the European Space Agency's (ESA's) Rosetta spacecraft has spied its approaching target and the coma – the "halo" made primarily out of ice and dust that gives the comet its fuzzy appearance – that is developing around its nucleus. At more than 600 million km (373 million miles) from the Sun, the opportunity to observe the early onset of coma production at such distances promises to add much to our knowledge of the life-cycle of a comet as it wends its way around the solar system.

B612 Foundation highlights the risk of city-destroying asteroids

By - April 23, 2014 4 Pictures
The California-based B612 Foundation has released a video displaying the distribution of 26 multi-kiloton asteroid impacts known to have struck the Earth since the year 2000. Many of the impacts – detected by a network of satellites operated by the Nuclear Test Ban Treaty Organization – exploded with a force greater than that of the city-leveling bomb dropped on Hiroshima, which had an explosive yield of 15 kilotons.

OSIRIS-REx asteroid sample return spacecraft gets go-ahead

By - April 12, 2014 2 Pictures
Getting hit by a giant asteroid can ruin your whole day, so the first United States mission to visit an asteroid and return a sample presents a huge challenge. Lockheed Martin has announced that NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has passed a comprehensive technical review, giving the green light for Lockheed to begin building the spacecraft in anticipation of a launch in 2016.

SpaceHabs: One man's architectural vision for colonizing Mars

By - April 8, 2014 20 Pictures
With a projected settlement date of 2025, the Mars One project has received over 200,000 applications for the one way trip to the Red Planet. But creating a living, sustainable community on the distant planet for the select inhabitants will require not only unique technological and engineering solutions, but also novel architectural systems. Bryan Versteeg is a conceptual designer who’s been working with the Mars One team in anticipation of the planet’s eventual colonization. Read More

Caught on video: Asteroid impacts on Moon's surface

By - February 25, 2014 1 Picture
A meter-wide (3 ft) asteroid impacted the Moon's surface September 11, 2013, producing a bright explosion and digging a new crater about 40 meters (130 ft) in diameter. The video of the event shows a bright flash of light against the stark blackness of the Moon's dark side. Similar in brilliance to the brightest stars in the Big Dipper, the asteroid impact is the largest confirmed impact on the Moon since continuous monitoring started some 15 years ago. Read More

Is Ceres an oasis between Mars and Jupiter?

By - January 27, 2014 7 Pictures
In mid-2015, the asteroid probe Dawn is scheduled to establish orbit around Ceres, the only dwarf planet in the inner Solar System, as well as the largest asteroid, to begin roughly six months of close-up observation. The level of interest in this mission has significantly increased with the detection by the ESA's Herschel space observatory of plumes of water vapor being exuded from Ceres' surface from a pair of local sources.

ESA awaiting signal from Rosetta comet probe

By - January 19, 2014 12 Pictures
Like nervous parents, scientists and engineers at ESA are pacing the floor of mission control as they await word of whether or not the Rosetta spacecraft has survived 31 months of hibernation. The unmanned comet chaser was scheduled to reactivate itself today at 10:00 GMT, but the time required to complete the operation and the distance a radio signal must travel back to Earth means that the space agency will not know until at least 17:30 GMT if the probe is operating again or has become deep space scrap.

NASA's NEOWISE discovers its first new near-Earth asteroid since returning to work

By - January 8, 2014 4 Pictures
NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) may have only come back online last September after a 31-month hibernation, but it’s already producing results. According to the space agency, the unmanned spacecraft discovered a never-before-seen asteroid on December 29 – the first discovery of its new mission to seek out potentially hazardous near-Earth objects (NEOs).
