The mission has concluded that the solar-powered lander has run out of energy after more than four years on the Red Planet.

Their first EV could possibly roll out with an integrated PlayStation 5.
Japanese industrial giants Sony and Honda formally joined forces earlier this year to take on the might of Tesla in the electric vehicle (EV) space. The collaborative effort will first be unveiled at the CES 2023, scheduled to be held in Las Vegas in a fortnight from now, The Verge.

Solar energy is reaching new heights faster than ever.
A tandem solar cell developed by researchers at the Helmholtz Zentrum Berlin (HZB) has converted 32.5 percent of incident solar radiation into electrical energy, a world record. The achievement was certified by the European Solar Test Installation (ESTI) in Italy, a university press release said.
As the demand for renewable energy grows, researchers are looking at ways of increasing the efficiency of solar cells. This enables more energy to be harvested from the same area of land deployed to generate power. There has been significant success when halide perovskites have been used to make solar cells.

Zeppelins, the rigid airships most famously epitomized by the Hindenburg, now seem kind of retro, rather than the image of futurity they represented in the 1930s. But they could be about to make a comeback in a big way — courtesy of a new aluminum-shelled, solar-powered airship that’s being built by the U.K.-based company Varialift Airships.
According to the company’s CEO Alan Handley, the airship will be capable of making a transatlantic flight from the United Kingdom to the United States, consuming just 8% of the fuel of a regular airplane. It will be powered by a pair of solar-powered engines and two conventional jet engines.
While its lack of onboard battery would limit travel to daylight hours, and its speed will only be approximately half that of a Boeing 747, the Varialift airship does promise to be a useful cargo carrier. Its creators claim that it will be able to carry loads ranging from 50 to 250 tons. Larger models with payloads up to 3,000 tons aren’t out of the question either. Bulky cargo such as electricity pylons, wind turbine blades, and towers, or even prefabricated structures such as oil rigs could be carried underneath using cables. That means that cargo will have a weight limit, but no practical size limit.
Around 38% of the world’s total landmass is used for agriculture – yet hunger is worsening, and food security is in crisis, threatened by pressures including climate change, conflict and global recessions.
While there’s no one-stop solution, technology can help to fill some of the gaps. Mechanical engineer Josie Hughes is on a mission to show how robotics can play a role in our everyday lives, particularly when it comes to food. Starting with LEGO robots as a child, the Cambridge graduate now leads the Computational Robot Design & Fabrication Lab (CREATE) at the Swiss Federal Institute of Technology Lausanne (EPFL), where she’s one of the youngest researchers to join as a tenure-track assistant professor.
One of her innovations, a raspberry-picking robot powered by artificial intelligence, could help make farming more efficient and cost-effective, and solve labor shortages – which in the UK alone left £60 million ($74 million) worth of fruit and vegetables rotting in fields this summer. CNN spoke with Hughes about her research, and when robots might be harvesting your next meal.
Majik Water is a social enterprise that specializes in air to water technologies in arid and semi arid regions. They are creating a new source of affordable, clean drinking water for water scarce communities. If you have air, you can have drinking water.
Technology developed at Argonne can help narrow the field of candidates for molten salts, a new study demonstrates.
Scientists are searching for new materials to advance the next generation of nuclear power plants. In a recent study, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory showed how artificial intelligence could help pinpoint the right types of molten salts, a key component for advanced nuclear reactors.
The ability to absorb and store heat makes molten salt important to clean energy and national climate goals. Molten salts can serve as both coolant and fuel in nuclear power reactors that generate electricity without emitting greenhouse gases. They can also store large amounts of energy, which is increasingly needed on an electric grid with fluctuating sources such as wind and solar power.
The carbon-negative concrete blocks absorb more CO2 during production than they emit.
A Limburg (Netherlands) company called Masterbloc has engineered an eco-friendly building material from steel slag left over from the steel industry, according to an article by The Brussels Times.
The company CEO Bjorn Gubbels claims the block stores CO2 and can help boost the circular economy.

In April, Tesla Inc TSLA CEO Elon Musk said he was done selling Tesla shares to help finance his ongoing overhaul at Twitter.
Since then, he jettisoned more than $20 billion worth of Tesla stock and has continued the selling spree this week.
