Catch a falling rocket with a helicopter? Yes, that's the plan

Small rocket builder Rocket Lab USA Inc is gearing up for a mission that seems more appropriate for a big-budget action movie: catching a falling four-story-tall rocket booster with a helicopter. The Long Beach, California-based company is trying to slash the cost of spaceflight by reusing its rockets, a trend pioneered by billionaire tech entrepreneur Elon Musk's SpaceX.

Argentine scientists discover fossil of largest raptor dinosaur

A team of Argentine paleontologists digging in Patagonia have discovered the remains of the largest dinosaur belonging to the raptor family ever recorded. The dinosaur, a new species named Maip macrothorax, was between nine and 10 meters (29.5 and 32.8 feet) long, while other "megaraptors" were no longer than nine meters, said one of the scientists who participated in the discovery, Mauro Aranciaga Rolando.

Fossils of giant marine reptiles found high in the Swiss Alps

Fossils from some of the largest creatures ever to swim Earth's oceans - whale-sized marine reptiles called ichthyosaurs - have been found in a counterintuitive place: atop three mountains in the Swiss Alps up to 8,990 feet (2,740 meters) above sea level. Scientists on Thursday described rib and vertebrae fossils from two ichthyosaur individuals: one about 69 feet (21 meters) long and the other about 49 feet (15 meters). They described from a third individual the largest-known tooth from any ichthyosaur with a base 2.4 inches (6 cm) wide and an estimated length of 6 inches (15 cm), suggestive of a fearsome predator.
