THE tragedy was witnessed by millions of Americans who watched on live television for the Challenger to make history. But why did the space shuttle break apart, and how many people died? Here's what we know about the 73-second doomed flight. When was the Challenger disaster? The NASA shuttle orbiter broke apart just 73 seconds into its flight on January 28, 1986, at 11.39am local time. It was the tenth flight the Space Shuttle Challenger had taken. The spacecraft fell apart off the coast of Cape Canaveral in Florida. The crew compartment ascended to an altitude of 12.3 miles before free-falling into the Atlantic Ocean. Why did the space shuttle break apart? The vehicle began disintegrating after a join in its right solid rocket booster (SRB) failed at liftoff. This was down to the unusually cold weather that the O-ring seals were not designed to handle. As the shuttle ascended, one of the seals opened enough to allow a plume of exhaust to leak out. Hot gases than bathed the cold … [Read more...] about When was the Challenger disaster, why did the space shuttle break apart and how many people died?

The South African-born engineer and entrepreneur Elon Musk made his billions with an internet payments company that merged with PayPal; Jeff Bezos, meanwhile, founded Amazon. But both had long wanted to make their own spaceships, and boldly go. Now Musk has SpaceX, as well as his electric car company, Tesla Motors, and Bezos has Blue Origin. They build rockets, not all of which blow up on the launch pad. Indeed, SpaceX has become a thriving concern, blasting commercial and military satellites into orbit, and resupplying the ISS. Blue Origin has hitherto been more secretive, financed primarily by fantastic injections of Bezos's own cash, but it now has commercial missions lined up for 2020. As The Space Barons relates, our two plutocrats have intriguingly different motivations for getting humanity back into space travel. For Musk, founding a colony on Mars is a necessary Plan B to avoid the extinction of the human race by some catastrophic event, such as the collision with Earth of a … [Read more...] about The Space Barons: the Silicon Valley heavyweights in a new space race
NASA has cleared the way for Boeing (NYSE: BA) to deliver an astronaut to the International Space Station during what was supposed to be a manned test of its Starliner spacecraft, showing faith in the aerospace giant and its transport vessel to solve the growing problem of how to get American astronauts into orbit. On April 5, the space agency said it had updated its Commercial Crew Transportation Capability contract with Boeing to allow the test voyage to take up to six months, up from two weeks, and carry a third astronaut instead of just the previously agreed-upon two-person crew. The changes would in effect make the Starliner test flight a normal mission. Although Boeing bills itself as a jack-of-all-trades with operations spanning commercial aerospace, defense, and space, in recent years the commercial segment has been the growth engine. Space and defense generated just 22% of total revenue in 2017. If Boeing is to counter that trend, it is going to need multiple project wins on … [Read more...] about NASA Hopes to Have Boeing Delivering Astronauts to the Space Station Sooner Than Planned
A glance at some of the world's most-read news websites will have left many readers under the impression Buzz Aldrin had confirmed he saw an alien craft. But he has almost certainly not. The institution behind the claim will not reveal how the claim has been proven, Aldrin himself has denied it, and at least some of the astronauts named didn't actually take part in the study, since two of them are dead. The claim, originally published in the Daily Star, has now been repeated by many of the world’s biggest websites and across the world. The reports – many of which cast little doubt on the initial claims – have been shared thousands of times.

Dark matter is even more mysterious than we thought, according to new research. The elusive matter makes up far more of the universe than the stuff we see around us. But it still remains almost entirely mysterious: we only know it exists through its interactions with the visible universe, and know very little about it. Scientists have now revealed that a previous breakthrough – which at the time appeared that it could cast some light on dark matter – might actually have been wrong. Three years, researchers were excited after they noticed a galaxy in a cluster appeared to have become separated from the dark matter that surrounded it.
