Estonian mission will deploy ‘plasma brake’ to deorbit satellites faster

Estonia’s ESTCube-2 satellite is set for takeoff this week with an ambitious mission: the first demonstration of “plasma brake” technology to deorbit satellites faster and help reduce space debris. To achieve this, ESTCube-2 will also for the first time use electric sail (or e-sail) technology. This is a type of tether devised by Pekka Janhunen of the Finnish Meterological Institute (FMI) as a propellant-free mechanism of exploring the Solar System. The satellite’s e-sail is an interweaved aluminium tether line 50 metres in length. It’s made up of 50-micrometre wires, no bigger than the average human hair. In low-Earth orbit, the…

Swiss startup believes this forgotten element is the key to safe nuclear energy

Nuclear energy is undergoing a renaissance. Across Europe, governments are pouring huge amounts of money into new power plants while startups are busily working on smaller, modular alternatives. Most of these plants rely on uranium, the radioactive metal that fuelled the atomic age (and contributed to a couple of catastrophic meltdowns). However, Swiss startup Transmutex wants to reinvent nuclear energy using a lesser-known element called thorium. Uranium’s forgotten cousin Thorium is a lead-like metal that is mildly reactive, but four times more abundant than uranium and a lot safer to handle. However, thorium is a fissionable material but not a… This story continues at The Next Web from The Next Web https://ift.tt/ideQqVM

Insta mules and crypto mixers: How tech is transforming money laundering

On the shallow surface of Instagram, Ramon “Hushpuppi” Abbas was a quintessential influencer. The flamboyant Nigerian portrayed a lavish lifestyle of private jets, luxury cars, and designer clothes.

The 41-year-old was “one of the most prolific money launderers in the world,” according to the FBI. By his own admission, Hushpuppi conspired to launder over $300mn in just 18 months. One of his alleged clients was a certain Kim Jong Un — the supreme leader of North Korea. With his… This story continues at The Next Web from The Next Web https://ift.tt/rd549ui
