LOS ANGELES (AP) — Five years after a NASA satellite to track carbon dioxide plunged into the ocean after liftoff, the space agency is launching a carbon copy — this time on a different rocket.
The $468 million mission is designed to study the main driver of climate change emitted from smokestacks and tailpipes. Some of the carbon dioxide is sucked up by trees and oceans, and the rest is lofted into the atmosphere, trapping the sun's heat and warming the planet.
LOS ANGELES (AP) — NASA has tested new technology designed to bring spacecraft — and one day even astronauts — safely down to Mars, with the agency declaring the experiment a qualified success even though a giant parachute got tangled on the way down.
Saturday's $150 million experiment is the first of three involving the Low Density Supersonic Decelerator vehicle. Tests are being conducted at high altitude on Earth to mimic descent through the thin atmosphere of the Red Planet.
WASHINGTON (AP) — The Supreme Court has ruled that a startup Internet company has to pay broadcasters when it takes television programs from the airwaves and allows subscribers to watch them on smartphones and other portable devices.
LONDON (AP) — Britain's fertility regulator says controversial techniques to create embryos from the DNA of three people "do not appear to be unsafe" even though no one has ever received the treatment, according to a new report released Tuesday.
