NASA selects proposals for smallsats built to study deep space

NASA is expanding plans to use small satellites (aka smallsats) to explore the Solar System. The agency has picked two proposals for smallsat technology that would improve observations in deep space, where they could help improve models that predict...

Australia Square Kilometre Array Pathfinder goes live as the world’s quickest radio telescope

Australia Square Kilometre Array Pathfinder goes live as the world's quickest radio telescope

Australia's Shire of Murchison is quickly becoming a hotbed for radio telescopes. As of of Friday, the territory is operating the world's fastest radio telescope in the form of the Australia Square Kilometre Array Pathfinder (ASKAP). The 36-antenna grid's eventual use of six phased array feeds, each with 188 receivers, will let it scan a field of view 150 times larger than the moon's visible area while processing that information much faster than a typical single-pixel radio telescope feed -- CSIRO estimates that an image of the Centaurus A galaxy that would take 10,000 hours to process with rivals should take five minutes with ASKAP. Ultimately, the array should grow to 60 antennas as part of the Square Kilometer Array, which includes South Africa in its hunt for pulsars, quasars and other unique parts of the universe. Just don't get your hopes up for booking alien listening sessions anytime soon. Commissioning started virtually as soon as the ribbon was cut, and scientists have already scheduled their usage slots for the next five years. We're sure we'll get over any frustration when we see the first ASKAP results published within the next year.

IBM cluster powers Murchison Widefield Array’s radio telescope, answers mysteries of the universe faster than ever (video)

IBM cluster powers Murchison Widefield Array's radio telescope, answers mysteries of the universe faster than ever video

Radio telescope operators have as much of a problem coping with the avalanche of data as getting that information in the first place. The Victoria University of Wellington is all too aware and is leaning on IBM for a powerful (if very tongue-tying) iDataPlex dx360 M3 compute cluster to sift through the deluge at the upcoming Murchison Widefield Array. Combined, the 4,096 array antennas probing deep space and solar atmospherics will have the Xeon-based cluster tackling signal data to the tune of 8GB per second, and about 50TB per day -- that's a Nexus 7's worth of astronomy faster than you can sneeze, folks. A 10Gbps network connection will feed the results to Perth to save scientists a roughly 435-mile trek. Construction is still in mid-stride, but the $51 million Australian ($52.2 million US) being spent on the Murchison array may be worthwhile if it helps solve the riddles of star formation and solar flares.
