What does NASA have planned for 2021 other than the commissioning of the Webb telescope? What about SpaceX and Blue Origin? With the landing of the Perseverance rover on Mars, the launch of the Lucy and DART missions, and the Juno probe’s continuing incredible work at Jupiter, 2021 was a spectacular success. Expect the same, but different in the next 12 months, with a bigger focus on our nearest neighbor—the Moon.

Here’s everything you need to know about space exploration, NASA missions, and space tourism in 2022:

Could water-recycling suits help future astronauts survive on Mars?

It’s one of the most well-known pieces of speculative technology in science fiction: the Stillsuit.

As an essential feature of Frank Herbert’s Dune, the Stillsuit is the body-fluid recycling full-body suit worn by the Fremen of Arrakis, a technological adaptation to a desert world with almost no water but home to an extremely valuable resource that leads to human colonization of the barren planet.

While there isn’t any of the spice melange on Mars (at least none that we know of), Dune’s Arrakis has some very strong parallels to the red planet just down the way from us, and some important lessons to teach about survival in such an unforgiving environment.

The Chinese inroads into space have got strategic circles abuzz with discussions about a possible revival of a Cold War-type competition between the US and the erstwhile Soviet Union.

China has yet again made headlines with a move that goes beyond just sending missions to the Moon or Mars. It has claimed to have launched a satellite that could take high-resolution photos of American cities from space, which can capture even details of a vehicle’s number plate.

According to experts, a Chinese satellite captured photographs of a vast region around a US city in just 42 seconds, crisp enough to recognize a military vehicle on the street and tell what type of weapon it might be carrying.

An international scientific group with outstanding Valencian participation has managed to measure for the first time oscillations in the brightness of a magnetar during its most violent moments. In just a 10th of a second, the magnetar released energy equivalent to that produced by the sun in 100,000 years. The observation was carried out without human intervention, thanks to an artificial intelligence system developed at the Image Processing Laboratory (IPL) of the University of Valencia.

Among , objects that can contain a half-million times the mass of the Earth in a diameter of about 20 kilometers, are magnetars, a small group with the most intense magnetic fields known. These objects, of which only 30 are known, suffer violent eruptions that are still little known due to their unexpected nature and their duration of barely 10ths of a second. Detecting them is a challenge for science and technology.

Over the past 20 years, scientists have wondered if there are high frequency oscillations in the magnetars. The team recently published their study of the of a magnetar in the journal Nature. They measured oscillations in the brightness of the magnetar during its most violent moments. These episodes are a crucial component in understanding giant magnetar eruptions. The work was conducted by six researchers from the University of Valencia and Spanish collaborators.

With hundreds of times more food per acre than regular farms.

Vertical farming is a revolutionary form of agriculture. As its name suggests, it’s a form of agriculture that is specifically designed to facilitate agricultural production inside vertical structures. These farms can be created inside old warehouses, used shipping containers, greenhouses, or other buildings, saving space and energy.

As a more sustainable method of farming, vertical farming tends to require much less energy than regular farming which is estimated to be 95% less water since the used water in farming can be recycled and reused.
