Launched in 2018 on a mission to study the Sun from close proximity, NASA’s Parker Solar Probe continues to edge closer and closer to its target, setting one new record after another. The latest came during a close approach today, where the spacecraft exceeded blistering speeds of 330,000 mph (532,000 km/h) as it began its eighth loop of the Sun.
A team of scientists at the University College London has shed new light on the Antikythera Mechanism – the world’s first computer and one of the ancient world’s greatest technological mysteries. Using new imaging data, the multidisciplinary UCL Antikythera Research Team found that the 2,000-year-old device was not only a calculator, but an accurate model of the Cosmos as it was known to the ancient Greeks.
Faster-than-light (FTL) travel is a staple of sci-fi, hand-waving away multi-millennia journeys between stars. Such a technology would of course be incredibly handy to us in the real world, and while these “warp drives” have been considered theoretically possible, they usually involve exotic physics that are out of our reach. Now, astrophysicist Erik Lentz has outlined a new theoretical design that could allow FTL travel based on conventional physics.
A student-built CubeSat from the University of Michigan will investigate whether small satellites can be maintained in low Earth orbit without thrusters or propellant. Scheduled to launch from the Mojave Air and Space Port on Virgin Orbit’s Launch Demo 2 on January 10, 2020, the Miniature Tether Electrodynamics Experiment-1 (MiTEE-1) will test the concept of using the Earth’s magnetic field to generate thrust.
It’s rare that gravel gets scientists so excited, but these are no ordinary rocks. They’re the samples returned to Earth by Hayabusa2 after its 5.24-billion-km round trip to asteroid Ryugu, and this is our first glimpse at them after the spacecraft landed in the Australian Outback on December 6 and its sample container was transported to Japan.
SpaceX has been making controlled landings of its Falcon 9 boosters to allow them to be reused for a number of years now. Such landings involve the rockets touching down, be it on a boat or a launch pad, using legs built into the rocket. But SpaceX CEO and founder Elon Musk has revealed different plans for the Falcon 9’s bigger sibling, the Super Heavy, announcing the intention to have the launch tower arm catch the booster.
