Pioneering theoretical physicist and science popularizer Stephen Hawking has passed away at the age of 76. Details have not been released yet, but the BBC reports that his children Lucy, Robert and Tim have released a statement saying, “We are deeply saddened that our beloved father passed away today. He was a great scientist and an extraordinary man whose work and legacy will live on for many years.” read more

Black Holes Bigger than Supermassive Found

Since they’re basically invisible, it can be hard to pin down just how big a black hole is. They can range anywhere from a few times the mass of the Sun up to millions or billions times that mass, but there’s a potential class that are even bigger than that. read more

The US Navy has completed the latest in a series of sea trials to work out the bugs of recovering NASA’s Orion space capsule after its end-of-mission splashdown. The San Antonio-class amphibious transport dock USS Anchorage (LPD 23) completed Underway Recovery Test-6 (URT-6) on January 23, which involved the launch and recovery by special boat teams and Navy divers of a floating mock-up of the spacecraft under a variety of sea conditions, at night as well as daytime. read more

Growing Potatoes on Mars

Gee – I wonder where they got this idea. If you’ve seen the movie, The Martian, you obviously know!

With dangerous amounts of radiation, a thin atmosphere and frigid temperatures, the first people to land on Mars will have a fight on their hands to survive. And if we do figure out how to endure these harsh conditions, what will we do when dinner time rolls around? To explore ways these pioneers might be able to live off the land, scientists have been trying to grow potatoes on Earth in Mars-like conditions. The early results are now in and are described as positive. read more

ARCA Space Corporation has announced its linear aerospike engine is ready to start ground tests as the company moves towards installing the engine in its Demonstrator 3 rocket. Designed to power the world’s first operational Single-Stage-To-Orbit (SSTO) satellite launcher, the engine took only 60 days to complete from when fabrication began. read more

In 1996, scientists discovered what may be the strangest stone ever found, in an equally strange section of the Sahara desert that’s littered with unique yellow glass. Nicknamed the Hypatia stone, the relic was later found to be extraterrestrial in origin, but was unlike any known kind of meteorite or comet. A new study has deepened the mystery even further, finding that Hypatia could predate the formation of the Solar System, or have interstellar origins. read more

NASA has ramped up its next phase of space exploration by green lighting further development of two unmanned mission concepts. Scheduled to launch sometime in the mid-2020s, the proposed missions include the Comet Astrobiology Exploration Sample Return (CAESAR) spacecraft, which is designed to bring back comet materials to Earth, and the Dragonfly dual quadcopter, which is designed to fly about in the atmosphere of Saturn’s largest moon, Titan. read more

Magnetic Sail to Act as Spacecraft Braking System

Our nearest stellar neighbor, Alpha Centauri, is just four light-years from Earth, and while that’s pretty close in the grand scheme of things, we can’t just pop over to borrow some milk.With our current technology, the journey would take tens of thousands of years, but there are plans for tiny unmanned probes that could trek there in as little as 20 years. read more
