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.

GOCE gravity-measuring satellite gives in to gravity

GOCE gravity-measuring satellite gives in to gravity

The GOCE satellite we reported to be falling to Earth has finally succumbed to gravity entirely, breaking up into dozens of remnants weighing 20-25% of its original one ton, reports the BBC. It didn't strike any populated areas as it showered down this Sunday afternoon. Interestingly, the extremely low-orbiting observation satellite was designed in 2009 to run out of orbit-maintaining fuel right about now and fall, just, you know, anywhere. No big deal.

Remnants of GOCE satellite may hit Earth this weekend

Remnants of GOCE satellite may hit Earth this weekend

A satellite put into orbit around the Earth by the European Space Agency called the Gravity field and steady-state Ocean Circulation Explorer or GOCE has completed its mission. Rather than leaving the satellite aimlessly orbiting the planet forever, the ESA is having the satellite reenter the Earth's atmosphere. The satellite weighs about ton and experts believe that some parts of the satellite will impact the surface of the earth.

Sirius XM Radio’s FM-6 satellite launch is successful

Sirius XM Radio’s FM-6 satellite launch is successful

Sirius XM radio has been around for a long time and like many services that rely on satellites, the more satellites the more service can be offered. Sirius XM and Space Systems/Loral (SSL) have announced that the Sirius FM-6 satellite launch is going according to plan so far. The satellite has reportedly performed post-launch maneuvers as planned.

Solar flares hit Earth, SWPC predicts more grid fluctuations Monday

Solar flares hit Earth, SWPC predicts more grid fluctuations Monday

The National Oceanic and Atmospheric Administration's Space Weather Prediction Center predicts more solar storms Monday, disrupting the power grid and satellite communications. The predictions come during the peak of the current solar cycle, an eleven-year period of sun spot activity, solar storms, solar flares, and coronal mass ejections (CMEs). The effects on Earth are expected to be relatively mild.

SpyMeSat spy satellite tracking app lets you watch the watchers

SpyMeSat spy satellite tracking app lets you watch the watchers

A new consumer app tells you when spy satellites are overhead and potentially taking pictures of your area. SpyMeSat collates publicly available information about low-orbit spy satellites, issues alerts when one is overhead, and delivers technical information about the specific models of satellite that might be checking you out. It also tells you which nation owns a given satellite and who made it.

Lockheed Martin GPS III and OCX satellite launch and early orbit exercises demo successful

Lockheed Martin GPS III and OCX satellite launch and early orbit exercises demo successful

Lockheed Martin may be a name more closely tied with aircraft than anything else, but the company plays a significant role in the nation's space program. Lockheed and Raytheon have announced that they have successfully completed the third of five planned launch and early orbit exercises in a program to demonstrate that the GPS III satellite is ready for launch.

NASA reveals the solar system has a tail of its own

NASA reveals the solar system has a tail of its own

Many stunning objects in our solar system have tails. We see them most often in comets, meteoroids, asteroids, etc. Tails are formed when dust and ice on these objects burn up as they heat up, which results in debris letting loose and leaving a trail behind the comet. As it turns out, even our own solar system has a tail.

IRNSS navigation satellite launched to provide GPS-like services in India

IRNSS navigation satellite launched to provide GPS-like services in India

Last night, India successfully sent the satellite IRNSS-1A into space on one of its own rockets, making it the first of seven that will provide the country with a GPS-like navigation system. The rocket - called the Polar Satellite Launch Vehicle-C22 - was sent into space from the Satish Dhawan Space Center a little before midnight, marking "a new era of space applications [in India]," according to the Indian Space Research Organization.
