Expected to fetch between US$100,000 and $150,000, the replica is billed as a “test model of the Sputnik-1 satellite, one of …

As low-cost satellites become more common, researchers are turning their attention to improving their communications capabilities without adding crushing costs. A laser might, as NASA demonstrated earlier this year, be able to hit a gigabit per second – but the kit's expensive. So a pair of researchers from Florida-based …

Virtualization admins asked to explain what they do for a living may finally have something cooler than server consolidation to tell their kids, thanks to space upstart Vector deciding it's a good idea to create software-defined satellites that lift a hypervisor into orbit. Vector is building small rockets capable of lifting …

PICSnbnTM, the entity building and operating Australia's National Broadband Network (NBN) is just 34 days away from putting its very own satellite into orbit, and the organisation's communications operatives are starting to reveal a little about the bird. Here, for example, is a picture of the satellite. NBN SkyMuster satellite …

The University of Queensland has launched a new plan to use scramjets as satellite launch vehicles. Scramjets – aka supersonic combusting ramjets – require air to pass through an engine at supersonic speeds. Fuel is added to that supersonic air, then ignited, with the result being a supersonic plume of hot gas capable of …

Elon Musk wants to use his commercial SpaceX rockets to put satellites into orbit that will bring broadband to the next billion, but one of SpaceX's own customers has thrown a wrench into the works. Musk's plan involves encircling the globe with a few thousand high-capacity, low-latency satellites that the Tesla Motors boss …

The UK is entrusting a bunch of earth observation satellites to India's burgeoning space program. Three DMC3 optical observation satellites, along with a couple of other payloads, will be hoisted on July 10 by India's Polar Satellite Launch Vehicle (PSLV). It's the thirtieth mission for the PSLV, and also the heaviest. The …

The European Space Agency has successfully launched two new satellites into orbit as part of the Galileo project to offer EU citizens an alternative GPS system from late 2016. Late on Friday night, the brace of birds were blasted into space from Europe's Spaceport in French Guiana on top of a Soyuz rocket. The ESA's sats will …

Satellite navigation satellites turn out to be a lot like buses: there's none for ages, then three come along all at once. The first of the three launched on Wednesday to join the US Global Posititioning System constellation. The new bird is a Boeing-built GPS IIF, the ninth of its type and one of 12 in a fleet of satellites …

Private rocket firm SpaceX has settled its feud with the US Air Force over the rights to launch national security payloads. The company said that it would be able to compete with United Launch Alliance (ULA) for the ability to launch spy satellites. "Going forward, the Air Force will conduct competitions consistent with the …

Google is reportedly close to flinging $1bn at Elon Musk's SpaceX to bulk up investment in the private company's development of satellites for internet-based services. According to The Information, which cited several people familiar with the matter, a deal could be sealed soon. One source said that Google had agreed to value …

The European Space Agency (ESA) and Airbus Defence and Space say they have successfully sent data between satellites, using lasers, in a proof-of-concept demonstration of what both call the “SpaceDataHighway”. A canned statement from Airbus Defence and Space says two satellites - Sentinel-1A and Alphasat – were connected over …

Two Galileo satellites have been blasted into the wrong orbit, red-faced officials at the European Space Agency said today. Errant sats Doresa and Milena were launched on a Russian-built Soyuz rocket on Friday. But launch service outfit Arianespace admitted that the satellites failed to go into the correct orbit. " …

LIVE VIDIndia will today attempt to launch several satellites that will include Earth imaging and microsatellite payloads. The nation's Polar Satellite Launch Vehicle (PLSV) specialises in hoisting satellites into sun-synchronous polar orbits, with 25 successful launches recorded by April 2014.
