You’re aware that your cell service comes from cell towers. And that your mapping app is made possible by GPS satellites. And that wifi signals deliver your fail videos. But the sight of that invisible world is breathtaking. »
The GIF above, created by NASA, may leave you wondering why our government is building a planetary shield. Something you’re not telling us, NASA? According to the space agency, NASA’s shield plan has nothing to do with intergalactic threats—it’s protection against a danger on the ground. The space agency wants to… »
There are more than 2,250 satellites orbiting the Earth right now. But that abstract number didn’t prepare me for the shock of watching a Soviet-era rocket body whipping over my house in real-time.
When life gives you lemons, make lemonade, right? That, at least, is the motto the European Space Agency seems to have embraced with respect to two wayward satellites, which are being repurposed to provide the most accurate assessment yet of how gravity affects the passage of time. »
For over 50 years the Pentagon has had early warning satellites in orbit aimed at spotting launches of ballistic missiles, especially the big intercontinental kind that can fly around the globe in less than 30 minutes and bring about nuclear Armageddon. Recently, these satellites have made news for their “secondary… »
Here’s a wonderful photo from the US Navy showing their launch of a Mobile User Objective System communications satellite. The US Navy says the picture shows “a 5-meter payload fairing lifts off from Space Launch Complex-41”. I say the picture looks like it perfectly captures the idea of shooting for the stars. »
Part of a rocket engine crashes through the roof of a house in northeast China’s Shanxi province early Friday morning. »
Our lives today depend largely on systems and infrastructure that is invisible—a hidden landscape of webs and waves that come from cell towers, routers, satellites, and more. »
Alaska’s wildfires burned through their 5 millionth acre this week, making 2015 the third most destructive wildfire season ever recorded in the state, and NASA’s Terra satellite captured this striking image of the fires from above. »
Europe’s MSG-4 geostationary weather satellite is up and running after its launch on July 15. Earlier today, it’s Spinning Enhanced Visible Infrared Imager (SEVIRI) snapped its first image of Earth. And yes, we are impressed.
New Horizons’ fly-by of Pluto and its moons is the latest in a historic string of missions to objects in the solar system. But given that a fly-by lasts for just a short time, how much can we really get out of it? There’s no doubt that the mission will yield a great deal of interesting data, but surely more would be… »
Once you’ve put a satellite into space, that’s normally kind if it. There’s not usually a lot of replanning once your technology is in orbit, meaning that if you want to change something like the broadcast frequency, you’re stuck. That’s the reason these transforming satellites exist. »
Without even looking a century or so ahead when we’ll take a Virgin Galactic flight to spend our summers on Europa, there are many legal issues that are already confronting humanity in space. That’s why space lawyers are plenty busy today examining the particular economic and societal challenges found where Earth ends… »
