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.
Last year, we saw some details start to emerge around Rocket Lab’s vision to recover its spacecraft for reuse, plans that involved catching part of its Electron booster in mid-air with a helicopter. The private company is set to take an important step toward this objective, announcing that it will make its first attempt to recover the rocket’s first stage during a mission scheduled for later this month.
Astronomers have detected water on the Moon. While that statement might sound all too familiar in recent years, previous reports were based on spectral signatures that could have been other related compounds – this time, the detection is unambiguously water, in the molecular form we need.
