NASA, SpaceX, the Chinese government, and others helped make it a bumper year for space.
Rocket Lab, SpaceX, NASA and others helped propel the global spaceflight industry to a record year — and it could beat that record this year.
An updated forecast released today suggests that an out-of-control Russian tumbling back towards Earth could strike on Wednesday afternoon. In an updated forecast shared by Joseph Remis on satflare.com and Twitter, it shows the rocket re-entering around 12:44pm ET on Wednesday, January 5. Because the rocket is uncontrolled and could shift around erratically as it enters the Earth’s atmosphere, impact could occur +/- 7 hours of that estimated strike time. Returning to Earth in an out-of-control manner is the Persei upper stage rocket which carried a dummy payload into space as part of Russia’s Angara A5 rocket test.
On December 27, the Russian Angara A5 rocket lifted off from the Plesetsk Cosmodrome. Named after a river in Siberia, the Angara rocket is the first heavy-lift launch vehicle used by the Russians in decades. The December 27 launch was the third test flight of the giant rocket. While the launch was flawless, an upper-stage rocket failed to successfully fire.
While the Angara’s first two stages fired as planned, the third stage, a Persei rocket, failed to fire a second time. While the first fire helped put the dummy payload it was carrying into low-Earth orbit, the failure of the second fire failed to put the dummy payload into a geostationary orbit. Instead, the 20 ton mass is tumbling out of control to Earth. While Roscosmos shared pictures and a congratulations message before and immediately after the Angara launch, they’ve offered no comment on the Persei rocket and the failure for it to fire, deferring instead to the Russian military which was responsible for the launch. As of press time, the Russian military has offered no comment on this rocket.

One of the best thing about electric and hybrid vehicles is that the energy doesn’t get completely wasted when you need to brake. By using an electric motor as a generator, you can slow a vehicle down and put some of that kinetic energy into a battery pack so you can use it again later. Sure, there are conversion losses both going into the battery and coming back out to the wheels, so you don’t get a lot more than half of the energy back, but an ICE vehicle turns all of that energy into heat, which gets dissipated into the air.
Electric bikes, scooters, and other micromobility options can do regenerative braking, too. This is great for getting better range and doing fewer brake jobs, just like in a car.

A superthin electrolyte with three layers could deliver safe, fast-charging batteries.
These self-powered robots, which were inspired by water-walking insects, delivered chemicals while partially submerged in a solution.
British Lithium explains their pilot method of lithium extraction at its pilot plant, which was built over seven months and funded by government innovation agency Innovate UK:
Our unique pilot plant approach incorporates all processing stages – from quarrying through to high purity lithium carbonate production. This includes crushing, grinding, and beneficiating the ore, custom-built electric calcination at low temperatures, acid-free leaching, and multiple purification steps that include ion-exchange.
The company will manufacture 5 kilograms (11 pounds) of lithium carbonate per day from early 2022 in its pilot plant, which it says is enough to demonstrate its commercial value to customers. Once the process is fully developed, British Lithium will begin work on building a full-scale plant.
An artificial intelligence (AI) system that can identify diabetic retinopathy (DR) without physician assistance, including the most serious form that puts patients at risk of blindness, has outperformed expectations in a clinical trial. The commercial system successfully detected the presence and severity of the disease in 97% of eyes analysed. Deployment of such AI systems in primary care facilities for use by non-specialists could significantly increase access to eye exams that include DR evaluation, aiding in the diagnosis and treatment of the disease.
An artificial intelligence system that simplifies diabetes retinal screening could help save the vision of millions of people around the world.
