Rockets might be fiery fun, but they're big, bulky, and heavy. Ion thrusters, sci-fi as they sound, are real and these penny-sized ones are probably the future of steering small satellites in orbit. More »
DARPA Wants to Hack Together Old Satellites into New Satellites—While In Space
Launching satellites is a risky proposition—costing as much as $10,000 a pound to make orbit and little recourse if a critical piece malfunctions. So, DARPA has devised a...
...each) = ? resolution scope? When the satellites observing the sun are on opposite side of it and Earth is 90 degrees from both, they could all three focus on a target other than the sun. If they were to do this, would this be phenomenal resolution? Or would there need to be a few other...
Granted, it shows a ton of satellites going over between the time of 6-7 a.m. and 5 and 6 p.m. I have messed with the preferences and I still don't know what's wrong. Surely there has to be a lot more satellites going over that are visible at all times, and I know this for a fact. I do have the...
I used to have a pansat receiver and it used to work fine, and then after like 8 months the whole system shut down then never watched fta again. I was wondering if Fta is back again? Or even if the channels work, and where to get the files
The massive unmanned airborne vehicle (UAV) Global Observer is testing beautifully at the moment, and could one day (with a companion plane) provide much of the same coverage as a geosynchronous satellite for a fraction of the price. More »
I am in NY and want to know how many satellites can i get reach in my area i know of 119 but what others i have the receivers all hd but what satellite do i need to get all the options to all sats? Is it the 1000.2 or the 1000.4 ?

I just bought a new toshiba satellite C655D-S5048. I looked at the vents on the bottom and all have holes in it except for the cpu area. It has the layout but just looks like they forgot to put holes, is it supposed to be this way? I figure it is b/c it has the new anthlon 2 that uses only 25...
As data visualization has become more popular, bad infographics have started to crop up more and more frequently. Thankfully, we can always rely on Michael Paukner to make very, very good ones. Here he shows the satellites orbiting our planet.
Russia, as you might expect, has a whole lot of...
An Earth (mass M) satellite of mass m is in a circular orhit of radius r1. It is moved to an orbit with a larger radius r2, by way of an intermediate elliptical orbit, This is achieved by firing rockets for a short period when it is in the inner orbit and then firing the rockets again when it...
