Docking with the ISS may seem simple. However, actually doing so shows how difficult orbital mechanics can be. It's like traveling down a highway at 28,000 km/hr (17,000 mph) and parallel parking in an open garage on a multibillion-dollar ...
When a spacecraft reenters Earth's atmosphere at hypersonic velocities, its protective heat shield faces extreme conditions, including temperatures beyond 3,000 degrees Fahrenheit (1,650 degrees Celsius). To survive, the ...
What are the chances of finding extraterrestrial life in our solar system? Frank Postberg, a professor of planetary science at Freie Universität Berlin, has published a study in Science Advances with an international team ...
The robotic spacecraft that failed to rescue an aging NASA telescope plunged back to Earth on Friday less than three months after launching on the bold mission.
During NASA's SpaceX Crew-13 mission aboard the International Space Station, astronauts will support a series of biomedical and human performance investigations, including a new collaborative effort to study how spaceflight ...
Rocket launches are among the most violent ways humans have devised to travel. They generate millions of pounds of thrust and subject passengers to intense g-forces. Humans must undergo serious training to withstand those ...
For the first time, researchers have directly imaged the magnetization dynamics inside a spin Hall nano-oscillator—a nanoscale device that converts direct current into tunable microwave signals and is a promising building ...
Asteroids don't come with a warning label that they might one day hit Earth. While we don't know of any currently on course to do so, we are finding thousands of new ones each year, and there's always a chance that one could.
Switching to modern silicon solar cells could cut the cost of powering satellites by as much as 90% based on beginning-of-life (BOL) performance, according to a review led by the University of Surrey. The switch to silicon ...
Most kids learn in elementary school that the seasons are caused by Earth rotating on a tilted axis during its yearly orbit around the sun. The substantial tilt, about 23.5 degrees, is thought to be the result of an ancient ...
