On April 9, 2021 NASA demonstrated video footage on Mars Helicopter Ingenuity during rotor blades spinning test and HI-RES first image from Ingenuity. Launch day of Ingenuity Perseverance Mars Rover sent images of Ingenuity Helicopter’s rotor blades spin up within motor test. Ingenuity is going to fly on Mars on April 11–12. Rotor blades spinned up and are unlocked and helicopter is going to make high-rpm test. So next milestone is to spin up rotor blades full-speed for the first time on Mars (to the planned flight speed of ~2400 RPM) while still on the surface. Flight can’t happen too late in the Martian day either. A long flight late in the afternoon could deplete the battery without giving the Sun a chance to recharge it. You don’t want to go into that cold Martian night without a good bit of energy in the battery!

A team of theoretical physicists working with Microsoft today published an amazing pre-print research paper describing the universe as a self-learning system of evolutionary laws.

In other words: We live inside a computer that learns.

The big idea: Bostrom’s Simulation Argument has been a hot topic in science circles lately. We published “What if you’re living in a simulation, but there’s no computer” recently to posit a different theory, but Microsoft’s pulled a cosmic “hold my beer” with this paper.

The rotor blades on the Ingenuity helicopter were unlocked and the Perseverance rover’s arm was run through some checks in imagery acquired by NASA from Mars on April 8, 2021. Also, Perseverance captured a selfie with the Ingenuity helicopter in April 6 imagery. Full Story: https://www.space.com/mars-helicopter-ingenuity-unlocks-rotor-blades.

Onboard, Arctic Owl is equipped with all the requisite gear for oceanic expeditions. She features a helideck and an 850-square-foot hangar to accommodate your choppers. She also sports garages port and starboard that can hold a U-Boat Worx NEMO submarine, plus other toys, tenders and equipment. These smaller vessels can be deployed via her two cranes at the aft.

The spacious vessel can sleep up to 10 guests across six staterooms, including two master cabins with panoramic views. There is also space for six crew. Elsewhere, Arctic Owl features a large swimming pool and lounge at the bow, along with a spa on the flybridge.

Needless to say, Arctic Owl can certainly soar. She’s powered by twin Cummins hybrid diesel-electric engines that propel her to a top speed of 18 knots and a cruising speed of 16 knots. She also offers an impressive transatlantic range of 6000 nautical miles—that’s New York to the North Pole and back.

LIVERMORE (CBS SF) — It sounds like a scene from a Hollywood sci-fi thriller, but researchers from Lawrence Livermore National lab have joined with an Air Force team of technologists to test if a nuclear blast could be used to deflect an earth-threatening asteroid.

Whether it be Bruce Willis and his crew of oil drillers taking on an asteroid as it approaches earth in ‘Armageddon’ or Tia Leoni and her father awaiting a massive tidal wave from an asteroid strike in ‘Deep Impact,’ Hollywood has been fascinated by the threat from space.

Many have asked: Is that a rainbow on Mars? No. Rainbows aren’t possible here. Rainbows are created by light reflected off of round water droplets, but there isn’t enough water here to condense, and it’s too cold for liquid water in the atmosphere. This arc is a lens flare.
