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.

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.

Latest astronaut crew of 4 welcomed aboard International Space Station

Four astronauts, three from NASA and one from the European Space Agency, arrived at the International Space Station (ISS) on Wednesday and docked their SpaceX capsule, just two days after the last crew to depart the orbiting outpost returned to Earth. Rendezvous of the Crew Dragon capsule with the station less than 16 hours after launch from NASA's Kennedy Space Center in Cape Canaveral, Florida, marked one of the fastest flights by Elon Musk's SpaceX to the ISS from liftoff to docking, NASA webcast commentators said.

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.
