We may not be in an age of asteroid mining (yet), but asteroid prospecting has come a step closer as Planetary Resources announces that its Arkyd-6 satellite has successfully reached orbit. The six-unit CubeSat lifted off on Friday from the Indian Space Research Organization's (ISRO) Satish Dhawan Space Center in Southern India atop a Polar Satellite Launch Vehicle (PSLV) as a secondary paylo
The year just gone was a momentous one for furthering our understanding of the universe. SpaceX now routinely lands its rockets, NASA's Cassini craft crashed into Saturn in a spectacular and invaluable mission finale and researchers proved once and for all the existence of gravitational waves. All things going to plan, 2018 will also bring some landmark moments in space, beginning with the bi
The first interstellar object ever witnessed visiting the Solar System may have been and gone, but that hasn't stopped scientists from figuring out ways to visit it. A team from the Initiative for Interstellar Studies (i4is) has put forward a proposal for Project Lyra, a mission to launch a probe to chase and intercept the interstellar asteroid 'Oumuamua (1I/2017 U1), which passed close to th
The European Southern Observatory (ESO) has confirmed that the object provisionally designated A/2017 U1 is, in fact, an asteroid that came from outside the Solar System. The first-ever detected interstellar traveler, now named "`Oumuamua," turns out to be different from any object seen before and has been roaming between the stars for hundreds of millions of years...Continue Reading First in
An international team led by NASA has tested the International Asteroid Warning Network, which successfully tracked a potentially dangerous asteroid as it made a close flyby of the Earth in October. Billed as the first global exercise using a real asteroid to test global response capabilities, the TC4 Observation Campaign observed and plotted the orbit of the asteroid 012 TC4 as it passed wit
Over 65 million years ago, an asteroid some 10 km (6 mi) wide crashed into the Earth and wiped out the dinosaurs. Strangely, the legacy of this huge space rock could include a treatment for cancer after scientists from the UK and China demonstrated that iridium – a rare metal delivered to Earth by the asteroid – can be enlisted to kill cancer without harming healthy cells...Continue Reading D
On September 22, NASA's OSIRIS-REx spacecraft successfully completed a gravity assist flyby with Earth, that has set the probe on a course to rendezvous with the asteroid Bennu next year. At its closest point, OSIRIS-REx flew within 10,711 miles (17,237 km) of Earth's surface, and has captured some stunning imagery in the days following its vital pass...Continue Reading Asteroid probe snaps M
For the past year, NASA's OSIRIS-REx satellite has been on a solar orbit in our galaxy, readying itself for its ultimate goal of heading out to the asteroid Bennu, surveying it, and grabbing a sample from its surface. On Friday, Sept. 22, it will finally head off to its target with a little help from Earth's gravity...Continue Reading Asteroid hunter to slingshot off Earth's gravity this week
Last week, Earth was buzzed by asteroid 3122 Florence, the largest space rock NASA has seen come this close since it began tracking near-Earth objects (NEOs). Using a 70-m (230-ft) antenna at the Goldstone Deep Space Communications Complex, NASA took the opportunity to study Florence close up, confirming its monster size and revealing that it has two tiny moons...Continue Reading Massive Eart
Asteroids whizz past Earth on a regular basis, and thankfully they're usually only a few meters wide. But next month we're due for a close encounter with a monster space rock measuring 4.4 km (2.7 mi) across, making it the largest near-Earth object (NEO) to come this close to the planet since NASA began tracking them almost 20 years ago...Continue Reading 3-mile asteroid is the largest Earth-
