We kid you not: Solutions for the ambitious project to send humans to Mars have been inspired by the design of a child’s toy. NASA is testing an inflatable heat shield based on the idea of a stacking ring of donuts.
It was a year of amazing discoveries and historic missions; selfies on Mars, looking into the eye of a typhoon, and the first Vines made from space. But it was also a year of sadness, as the war in Gaza reached the skies – while some rockets did not.
A team of researchers says that extremely hot exoplanet orbiting red dwarf star could be bent out of shape and stretched out by the extreme tidal forces, and that such world could be discovered by new telescopes currently in the pipeline.
A NASA telescope designed to probe black holes and the vast expanses of the cosmos has set its sights on the burning heart of our own solar system, capturing the sun in all its high-energy x-ray glory.
Despite its hellish surface, Venus turns out to be quite an attractive planet for exploration. NASA scientists are developing a project of conquering its upper atmosphere – a fleet of solar-powered aircraft may build up a whole cloud city in the future.
A new NASA video gives a glance of what an astronaut could see from a spacecraft while rushing down through our planet’s atmosphere. The recording presents the last 10 minutes of the Orion’s test flight – before the final splash into the Pacific Ocean.
A briefcase-sized Canadian microsatellite has made a major contribution to mapping a promising waterworld. First spotted by NASA’s Kepler, the decade-old MOST telescope abandoned by Canada’s space agency has verified the discovery of another super-Earth.
