NASA hopes to fly soon in Martian air which is less than 1 percent the density of Earth’s atmosphere.

"A Piece of History

While Ingenuity will attempt the first powered, controlled flight on another planet, the first powered, controlled flight on Earth took place Dec. 17, 1903, on the windswept dunes of Kill Devil Hill, near Kitty Hawk, North Carolina. Orville and Wilbur Wright covered 120 feet in 12 seconds during the first flight. The Wright brothers made four flights that day, each longer than the previous.

A small amount of the material that covered one of the wings of the Wright brothers’ aircraft, known as the Flyer, during the first flight is now aboard Ingenuity. An insulative tape was used to wrap the small swatch of fabric around a cable located underneath the helicopter’s solar panel. The Wrights used the same type of material – an unbleached muslin called “Pride of the West” – to cover their glider and aircraft wings beginning in 1901. The Apollo 11 crew flew a different piece of the material, along with a small splinter of wood from the Wright Flyer, to the Moon and back during their iconic mission in July 1969."

JPL reports that the first flight of the Ingenuity Helicopter was SUCCESSFUL. They displayed video from the rover showing a successful liftoff and hover feet above the ground

"Males latch onto the female with their teeth and become 'sexual parasites,' eventually coalescing with the female until nothing is left of their form but their testes for reproduction," reads the post.

The telescope’s safe arrival is a relief to scientists who plan to spend the next 10 or more years using it to study ancient galaxies.

After traveling nearly one million miles, the James Webb Space Telescope arrived at its new home on Monday. The spacecraft’s arrival checks off another tricky step as scientists on Earth prepare to spend at least a decade using the observatory to study distant light from the beginning of time."

Oxford's JET lab smashes nuclear fusion energy output record

Scientists say they have made a major breakthrough in their quest to develop practical nuclear fusion - the energy process that powers the stars.
The UK-based JET laboratory has smashed its own world record for the amount of energy it can extract by squeezing together two forms of hydrogen.
The experiments produced 59 megajoules of energy over five seconds (11 megawatts of power).
This is more than double what was achieved in similar tests back in 1997.

It's not a massive energy output - only enough to boil about 60 kettles' worth of water. But the significance is that it validates design choices that have been made for an even bigger fusion reactor now being constructed in France.
"The JET experiments put us a step closer to fusion power," said Dr Joe Milnes, the head of operations at the reactor lab. "We've demonstrated that we can create a mini star inside of our machine and hold it there for five seconds and get high performance, which really takes us into a new realm."

The ITER facility in southern France is supported by a consortium of world governments, including from EU member states, the US, China and Russia It is expected to be the last step in proving nuclear fusion can become a reliable energy provider in the second half of this century.
Operating the power plants of the future based on fusion would produce no greenhouse gases and only very small amounts of short-lived radioactive waste.
"These experiments we've just completed had to work," said JET CEO Prof Ian Chapman. "If they hadn't then we'd have real concerns about whether ITER could meet its goals.
"This was high stakes and the fact that we achieved what we did was down to the brilliance of people and their trust in the scientific endeavour," he told BBC News.
Fusion works on the principle that energy can be released by forcing together atomic nuclei rather than by splitting them, as in the case of the fission reactions that drive existing nuclear power stations.
In the core of the Sun, huge gravitational pressures allow this to happen at temperatures of around 10 million Celsius. At the much lower pressures that are possible on Earth, temperatures to produce fusion need to be much higher - above 100 million Celsius.
No materials exist that can withstand direct contact with such heat. So, to achieve fusion in a lab, scientists have devised a solution in which a super-heated gas, or plasma, is held inside a doughnut-shaped magnetic field.
The Joint European Torus (JET), sited at Culham in Oxfordshire, has been pioneering this fusion approach for nearly 40 years. And for the past 10 years, it has been configured to replicate the anticipated ITER set-up.

The walls of the JET reactor were changed to a material made from beryllium and titanium
The French lab's preferred "fuel" to make the plasma will be a mix of two forms, or isotopes, of hydrogen called deuterium and tritium.
JET was asked to demonstrate a lining for the 80-cubic-metre toroidal vessel enclosing the magnetic field that would work efficiently with these isotopes.
For its record-breaking experiments in 1997, JET had used carbon, but carbon absorbs tritium, which is radioactive. So for the latest tests, new walls for the vessel were constructed out of the metals beryllium and titanium. These are 10 times less absorbent.
The JET science team then had to tune their plasma to work effectively in this new environment.
"This is a stunning result because they managed to demonstrate the greatest amount of energy output from the fusion reactions of any device in history," commented Dr Arthur Turrell, the author of The Star Builders: Nuclear Fusion And The Race To Power The Planet.
"It's a landmark because they demonstrated stability of the plasma over five seconds. That doesn't sound very long, but on a nuclear timescale, it's a very, very long time indeed. And it's very easy then to go from five seconds to five minutes, or five hours, or even longer."

JET can't actually run any longer because its copper electromagnets get too hot. For ITER, internally cooled superconducting magnets will be used.
Fusion reactions in the lab famously consume more energy to initiate than they can output. At Jet, two 500 megawatt flywheels are used to run the experiments.
But there is solid evidence that this deficit can be overcome in the future as the plasmas are scaled up. ITER's toroidal vessel volume will be 10 times that of JET. It's hoped the French lab will get to breakeven. The commercial power plants that come after should then show a net gain that could be fed into electricity grids.

Unfortunately, Ancient Aliens has no filter. However, I believe that some serious scientists like Paul Davies have advanced this idea.
Francis Crick also believed in panspermia.
