JAXA teams with GITAI for world-first private sector space robotics demo

Space robotics startup GITAI and the Japan Aerospace Exploration Agency (JAXA) are teaming up to produce the world’s first robotics demonstration in space by a private company. The new agreement under the JAXA Space Innovation through Partnership and Co-creation (J-SPARC) initiative aims to demonstrate the potential for robots to automate of the processing of specific tasks aboard the International Space Station (ISS).

Robotics is altering many aspects of our lives in many fields and one where it is particularly attractive is in the exploration and exploitation of space. Ironically, the great strides made in manned spaceflight since the first Vostok mission lifted off in 1961 have shown that not only is supporting astronauts in orbit challenging and expensive, there are also many tasks, like microgravity experiments, where the human touch isn’t the best choice.

These tasks often require complex, precise, and subtle movements that demand either a highly specialized and expensive bespoke apparatus or a robot. The GITAI/JAXA agreement will work on ways that robots can handle maintenance, scientific experiments, and other specific tasks aboard the ISS.

Earth is about to capture a new ‘mini moon’ (but it might not be a moon at all)

O,.o.

A new mini-moon might be about to join Earth’s orbit briefly, before being hurled back into space.

‘Minimoons’ are only a few feet across, and each tends to do a stint of around a few months in orbit – before resuming their previous lives as asteroids.

But this particular mini-moon may be a little different – as experts have suggested it’s not a moon at all, but man-made space junk.

Rosetta spacecraft detects unexpected ultraviolet aurora at a comet

Data from Southwest Research Institute-led instruments aboard ESA’s Rosetta spacecraft have helped reveal auroral emissions in the far ultraviolet around a comet for the first time.

At Earth, auroras are formed when charged particles from the Sun follow our planet’s to the north and south poles. There, solar particles strike atoms and molecules in Earth’s atmosphere, creating shimmering curtains of colorful light in high-latitude skies. Similar phenomena have been seen at various planets and moons in our and even around a distant star. SwRI’s instruments, the Alice far-ultraviolet (FUV) spectrograph and the Ion and Electron Sensor (IES), aided in detecting these novel phenomena at 67P/Churyumov-Gerasimenko (67P/C-G).

“Charged particles from the Sun streaming towards the comet in the solar wind interact with the gas surrounding the comet’s icy, dusty nucleus and create the auroras,” said SwRI Vice President Dr. Jim Burch who leads IES. “The IES instrument detected the electrons that caused the aurora.”

NASA Found Another Way Into Nuclear Fusion

O,.o.

NASA has unlocked nuclear fusion on a tiny scale, with a phenomenon called lattice confinement fusion that takes place in the narrow channels between atoms. In the reaction, the common nuclear fuel deuterium gets trapped in the “empty” atomic space in a solid metal. What results is a Goldilocks effect that’s neither supercooled nor superheated, but where atoms reach fusion-level energy.

☢️ You like nuclear. So do we. Let’s nerd out over it together.
