In late 2016, Nikola Motor Company founder Trevor Milton unveiled a prototype of the Nikola One truck, claiming it “fully functions and works, which is really incredible.” A couple years later, in January 2018, the company showed the Nikola One truck moving rapidly along a two-lane desert highway. But last week, the short-selling investment firm Hindenburg Research published a bombshell report,…

What are cloud streets?
Cloud streets are a manifestation of Earth’s atmosphere in motion. They’re mostly seen by satellites looking down on Earth, but people sometimes catch them from the ground, too. Check out these cool images! Source: https://earthsky.org/earth/what-are-cloud-streets…
Will More Powerful Processors Super-Charge NASA’s Mars Rovers?
The Texas Advanced Computer Center talks to Masahiro (Hiro) Ono, who leads the Robotic Surface Mobility Group at NASA’s Jet Propulsion Laboratory which led all the Mars rover missions (also one of the researchers who developed the software that allows the current rover to operate):
The Perseverance rover, which launched this summer, computes using RAD 750s — radiation-hardened single board computers manufactured…

CIA Declassifies Cold War-Era Plans for a ‘Nuclear Bird Drone’
“During the Cold War, the CIA considered building a bird-sized drone designed to spy on the communist bloc,” reports Popular Mechanics. “The drone would carry ‘black box’ spy packages into Russia and China, as well as take secret photographs — all while hiding in plain sight disguised as a bird…” The project envisioned a fleet of 12 bird-shaped drones, powered by…
Ceres’ bright spots come from salty water below
The mysterious bright spots on Ceres caused a sensation when the Dawn spacecraft first spied them in 2015. Now, they’re known to be salt deposits from a recent or ongoing percolation of briny water from a large reservoir in Ceres’ interior.

Planet Ceres Is An ‘Ocean World’ With Sea Water Beneath Surface, Mission Finds
The dwarf planet Ceres — long believed to be a barren space rock — is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed on Monday. The Guardian reports: Ceres is the largest object in the asteroid belt between Mars and Jupiter and has its own gravity, enabling the Nasa Dawn…
SpaceX’s Starship SN5 Testbed Successfully Makes 150m Controlled Flight
Zitchas writes: On Tuesday evening, SpaceX launched a testbed system which flew 150m into the air, hovered, and made a controlled landing. This testbed is noteworthy for being made out of stainless steel, as well as for being powered by a single off-center raptor engine. It demonstrates that the propulsion system can successfully compensate for the off-balanced propulsion via vectored thrust,…
Spacecraft Made From Ultra Thin Foam Could Reach Proxima Centauri In 185 Years
An anonymous reader quotes Newsweek:
A hypothetical spacecraft made from an extremely thin layer of a synthetic foam could technically make it to our closest neighboring star Proxima Centauri in just 185 years, scientists have said. If Voyager were to make the same journey, it would take around 73,000 years, according to NASA. In a study that is due to be published…
