New (?) ideas for utilizing space for business: hypergravity for isotopic enrichment
Posted by Klaus Baldauf in categories: business, energy, space
One night, as I was putting my daughter to bed and waiting for her to fall asleep, I tried to think of some new markets for space utilization.
We often hear about attempts to find industrial uses for microgravity for growing crystals, for purification of electronic materials (which is an actual thing with ACME Advanced Materials: http://www.a2-m.com/), maybe growth of certain metal foams, etc. However, in space, you’re in both a hard vacuum and not physically resting on anything, so you can spin up something, and it will simply keep on spinning (stably, if you spin it around the correct axis) nearly indefinitely without any additional energy input and no wear on bearings or anything. So in fact, you can get basically any gravity level you want, including HYPERgravity, nearly for free.
What are the applications of this?

RIPPA The Farm Robot Exterminates Pests And Weeds
Posted by Dan Kummer in categories: education, food, robotics/AI, space, sustainability
RIPPA, a fully autonomous robot, can cover five acres a day on a solar charge — finding and exterminating pests and weeds on every single plant over the equivalent of four football fields. Are robots like RIPPA the future of farming?
RIPPA stands for “Robot for Intelligent Perception and Precision Application”.

Astronauts install hi-def docking cameras for Crew Dragon, Starliner capsules
Posted by Genevieve Klien in category: space
In preparation for the commercial crewed modules that will arrive at the International Space Station soon, astronauts took a lengthy spacewalk to install some crucial equipment to the docking module. The extra-vehicular activity moved commander Drew Feustel to third on the list of all-time spacewalkers.

Stephen Hawking’s Voice Will Be Broadcast Into Space
Posted by Genevieve Klien in categories: entertainment, space
Hawking is being interred at Westminster Abbey on Friday, with a thousand members of the public (selected through a lottery system) present for the ceremony. The physicist’s remains will be placed between those of Isaac Newton and Charles Darwin.
His voice will be broadcast into space after the service honoring his life.
Hawking’s words “have been set to an original score by composer Vangelis, most famous for his Chariots of Fire film theme,” the BBC reports.

Spinlaunch has $40 million to fund development to first centrifuge space launch by 2022
Posted by Klaus Baldauf in categories: energy, space
SpinLaunch Inc. has closed a $35 million Series A funding round with a powerhouse syndicate of investors. Investors include Airbus Ventures, GV (formerly Google Ventures), and Kleiner Perkins. This syndicate joins institutional investors including Lauder Partners, ATW Partners, Bolt, and Starlight Ventures to total $40 million. Investment funds will be used to scale the team and technology, through first launch by 2022.
SpinLaunch is revolutionizing access to space by developing a kinetic energy launch system designed to provide the world’s lowest-cost orbital launch service for the rapidly growing small satellite industry. Their environmentally responsible approach is unmatched in the industry. SpinLaunch is currently considering four different states for potential launch sites within the United States.
Spinlaunch use large centrifuges to store energy and will then rapidly transfer that momentum into a catapult to send a payload to space at up to 4,800 kilometers per hour (3,000 mph). If successful, the acceleration architecture is projected to be both lower cost and use much less power, with the price of a single space launch reduced to under US$500,000.

Starts Testing Smallest ‘Spin Qubit’ Chip for Quantum Computing
Posted by Klaus Baldauf in categories: computing, quantum physics, space
Intel researchers are taking new steps toward quantum computers by testing a tiny new “spin qubit” chip. The new chip was created in Intel’s D1D Fab in Oregon using the same silicon manufacturing techniques that the company has perfected for creating billions of traditional computer chips. Smaller than a pencil’s eraser, it is the tiniest quantum computing chip Intel has made.
The new spin qubit chip runs at the extremely low temperatures required for quantum computing: roughly 460 degrees below zero Fahrenheit – 250 times colder than space.
The spin qubit chip does not contain transistors – the on/off switches that form the basis of today’s computing devices – but qubits (short for “quantum bits”) that can hold a single electron. The behavior of that single electron, which can be in multiple spin states simultaneously, offers vastly greater computing power than today’s transistors, and is the basis of quantum computing.
