Iridium Go! and Globalstar Sat-Fi give mobile hotspots some satellite love

Iridium Go! and Globalstar Sat-Fi give mobile hotspots some satellite love

Getting your notebook or other gadgets online if you've a big budget but no local service - say, perhaps, because you're desperate for WiFI in the desert or a remote jungle - is suddenly easier, with Globalstar and Iridium wading into the super-niche satellite data hotspot market. Globalstar's Sat-Fi and Iridium's Go! each promise the sort of cellular data sharing we're familiar with from mobile hotspots, only tapping into each company's satellite networks for coverage around the world.

Scientists want mini satellites to act as space cops to control traffic in orbit

Scientists want mini satellites to act as space cops to control traffic in orbit

A group of scientists from the Lawrence Livermore National Laboratory has devised a plan that will use mini satellites to act as cops in space. The little satellites would be used to help control traffic in space and refine trajectories to prevent collisions. The scientist recently used a series of images that were taken over a 60-hour period from a ground-based satellite to prove you can refine the orbit of another satellite in low earth orbit.

NASA Van Allen probes confirm Earth as giant particle accelerator

NASA Van Allen probes confirm Earth as giant particle accelerator

The NASA Van Allen twin probes launched last year have revealed that the Earth is a giant particle accelerator. Recently it was reported that particles in the magnetosphere sometimes accelerate across distances of a few hundred meters. But the newer discovery shows the acceleration can occur across hundreds of thousands of kilometers. The data will be helpful to to scientists helping satellite operators and the International Space Station to predict and prepare for the destructive tendencies of the seemingly random fluctuations that can occur in the magnetosphere.

NASA’s “MAVEN” Mars orbiter launched without a hitch

NASA’s “MAVEN” Mars orbiter launched without a hitch

NASA's Mars orbiter MAVEN launched successfully today from Cape Canaveral, Florida at 1:28PM EST. Once it arrives in orbit around the Red Planet, the Mars Atmosphere and Volatile EvolutioN orbiter will gather data about Mars' upper atmosphere to try and discover how exactly the planet got to be so dry and atmosphere-poor. Earlier probes suggest the planet used to be much more like Earth in terms of moisture and atmosphere thickness.

ESA Swarm satellites to chart Earth’s magnetic field

ESA Swarm satellites to chart Earth’s magnetic field

The European Space Agency will launch three satellites this week from Russia's Plesetsk Cosmodrome to gather data about the Earth's magnetic field over the next few years. The planet's magnetic poles have been shifting more and more rapidly over the last couple of decades, possibly as part of their usual flip from north to south every few hundred thousand years. The so-called "Swarm" mission will tell us about that and myriad other factors affecting the magnetic field surrounding Earth.
