The European Space Agency (ESA) and Roscosmos are preparing for the2022launch of the next mission in their joint ExoMars program, which is currently undergoing final testing before shipment to Kazakhstan for a launch in September next year.

The2022astrobiology mission will see the long-awaited Rosalind Franklin rover land on Mars with the help of the Russian Kazachok lander. The lander will also perform experiments on the Martian surface after deploying Rosalind Franklin as the two craft work together to search for signs of past life on the Red Planet.

After construction delays, missed Martian transfer windows, and the COVID-19 pandemic, Rosalind Franklin, Kazachok, and the other ExoMars2022mission systems have been completing important testing milestones ahead of shipment to Kazakhstan for launch on a Proton rocket next year.

Circa 2014

Scientists in a lab used a powerful laser to re-create what might have been the original spark of life on Earth.

The researchers zapped clay and a chemical soup with the laser to simulate the energy of a speeding asteroid smashing into the planet. They ended up creating what can be considered crucial pieces of the building blocks of .

The findings do not prove that this is how life started on Earth about 4 billion years ago, and some scientists were unimpressed with the results. But the experiment does bolster the long-held theory.

If you think at all about liquid crystals, you probably think of display technology. However, researchers have worked out a way to use an ink-jet-like process to 3D print iridescent colors using a liquid crystal elastomer. The process can mimic iridescent coloring found in nature and may have applications in things as diverse as antitheft tags, art objects, or materials with very special optical properties.

For example, one item created by the team is an arrow that only appears totally green when viewed from a certain angle. The optical properties depend on the thickness of the material which, being crystalline, self-organizes. Controlling the speed of deposition changes the thickness of the material which allows the printer to tune its optical properties.

The ink doesn’t sound too exotic to create, although the chemicals in it are an alphabet soup of unpronounceable organic compounds. At least they appeared available if you know where to shop for exotic chemicals.

What was that again about wind and solar power being unreliable? Some energy pundits are still tossing that old ball around, but meanwhile savvy investors are plowing billions into new energy storage facilities that spit out clean kilowatts on demand. Like they say, money talks, and in a fitting twist the latest example comes from the Golden State, California.

Massive New Energy Storage Facility For The Golden State

California has plenty of both wind and solar, and it also has an ambitious renewable energy goal, which makes it the perfect spot to launch ambitious clean power projects such as massive new energy storage facilities.

As part of a wave of solar water purifier research, scientists say they can turn even brackish groundwater into drinkable fresh water in about 30 minutes. The filtration uses a metal-organic framework, or MOF, which is a highly porous polymer made by combining metal particles with “coordinating” organic pieces called ligands. It can (and must!) be used in the sun, making it ideal for many applications in situ near sources of brackish water.
