A California startup wants to beam extra sunlight to Earth orbiting mirrors, but some are skeptical about whether the physics ...

The booster’s successful return also marks SpaceX's first polar orbit mission from Florida. In the wee hours of the morning in India, on the other side of the world, SpaceX was busy getting its ...

Flying at an altitude of around 45km, their polar orbit will require more juice than a typical orbit because the spacecraft can’t use the Earth’s rotation to boost velocity. This added energy ...

A Falcon 9 rocket on the SpainSat NG I mission carrying a communications satellite developed by Spanish company Hisdesat and the European Space Agency is targeting liftoff during a two-hour window ...

NASA’s Electrojet Zeeman Imaging Explorer (EZIE) has arrived at Vandenberg Space Force Base in California, where the ...

Four hundred million copper wires are now circling the globe in a polar orbit at an altitude of 2300 miles. These "needles" are part of Project West Ford which began in 1958 when it was first ...

PSLV C-35 launched a 371-kg weather satellite (SCATSAT-1) into the Polar Sun Synchronous Orbit (Polar SSO) at an altitude of 720 km. As per the standard PSLV configuration, this satellite was ...

Polar orbits are often used for earth-mapping, as well as for some weather satellites. Geostationary satellites take 24 hours to orbit the Earth, so the satellite appears to remain in the same ...

Astronomers have sent artificial satellites (satellites that are manmade) to orbit several Solar System objects, including Jupiter, the asteroid Vesta and Mars. Polar orbits take the satellites ...
