ESA offers CubeSats a deep space ride on asteroid mission

By - February 28, 2015 4 Pictures
CubeSats offer a way to get into space on the cheap. They're compact, inexpensive, and they can piggyback on larger launch payloads to get into orbit. The trouble is, this piggybacking is often like trying to hitchhike cross country on a ride that only goes to the edge of town. The European Space Agency is widening the scope a little by opening a competition for CubeSats to ride into deep space on its Asteroid Impact Mission (AIM). Read More

New Dawn Ceres image outdoes Hubble

The dwarf planet Ceres has come into sharper focus with NASA's Dawn spacecraft sending back the best images yet of the asteroid. Shot on January 25 from a distance of 147,000 mi (237,000 km) as the unmanned probe closes in for its March rendezvous, the resolution was 30 percent better than the best images obtained by the Hubble space telescope.

Dawn begins Ceres approach for orbital rendezvous

By - December 30, 2014 1 Picture
Like the end of a very long and eventful road trip, NASA's Dawn spacecraft has its main goal in sight. The space agency says that the unmanned probe has emerged from behind the Sun as it uses its ion propulsion to catch up with the dwarf planet Ceres in the asteroid belt and that mission control was able to re-establish contact. The craft has received instructions for executing a series of maneuvers that will take it on its final approach phase, which will end with it going into orbit around Ceres. Read More

Dawn space probe gets best look yet at Ceres

By - December 7, 2014 13 Pictures
The Dawn spacecraft has lifted the veil on another corner of the Solar System by taking its best image yet of the dwarf planet Ceres. The nine-pixel-wide image was taken from a distance of 740,000 mi (1.2 million km) from Ceres as part of the final calibration of Dawn's science camera as the unmanned probe approaches the 590 mi (950 km) wide planetoid, which it will rendezvous with and orbit in March of next year.

Hayabusa 2 launches on asteroid bombing mission

By - December 3, 2014 7 Pictures
Sometimes it seems as if the history of spaceflight is a long exercise in oneupsmanship with each agency trying to top the others. Case in point is Japan's Hayabusa2 mission, which, following the landing of Philae on on comet 67P/Churyumov–Gerasimenko last month, the Japan Aerospace Exploration Agency (JAXA) confirmed was successfully launched today at 1:22:04 pm JST from the Tanegashima Space Center on a mission to not only land on an asteroid, but to bomb it.

NASA seeks proposals for deep space missions

By - October 31, 2014 1 Picture
NASA is preparing to launch its Orion spacecraft in December and its Space Launch System (SLS) is scheduled to fly by 2018. However, impressive as this is, more is needed if buyer's regret isn't to set in. To avoid this, the space agency is asking for proposals to develop new technologies to send astronauts to the asteroids and Mars using "sustainable, evolvable, multi-use space capabilities."

ESA's bug-eyed "fly-eye" telescope to watch for Earth-threatening asteroids

By - September 12, 2014 2 Pictures
One aggravating property of the housefly is that swatting one is harder than it looks. That’s because flies have eyes designed for avoiding such a day-ruining event by detecting motion over a wide field of vision. Since asteroids have the potential to do to Earth what rolled newspapers do to flies, ESA is developing a telescope based on a fly’s eye as a new asteroid-hunting tool that could be the basis for a new asteroid defense network.
