On March 122021 NASA’s Perseverance Rover continues to find safe place to deploy Mars Helicopter Ingenuity and collect Mars Samples. Rover’s latest pics from Mars show Helicopter’s shield attached to bottom of the rover. Perseverance will gather samples from Martian rocks and soil using its drill. The rover will then store the sample cores in tubes on the Martian surface. This entire process is called “sample caching”. Mars 2021 is the first mission to demonstrate sample collection on Mars. It could potentially pave the way for future missions that could collect the samples and return them to Earth for intensive laboratory analysis.

For the first flight, the helicopter will take off a few feet from the ground, hover in the air for about 20 to 30 seconds, and land. That will be a major milestone: the very first powered flight in the extremely thin atmosphere of Mars. After that, the team will attempt additional experimental flights of incrementally farther distance and greater altitude. After the helicopter completes its technology demonstration, Perseverance will continue its scientific mission.

Chinese bitcoin miners have long dominated the global processing power that runs the bitcoin network with sophisticated equipment and access to cheap electricity. But now, a group of U.S. miners with deep pockets wants to conquer a greater share of the industry. Photo illustration: Clément Bürge.

Elon Musk’s SpaceX is preparing to further expand testing of its Starlink satellite internet in a test for the U.S. Air Force, an FCC request revealed.


Elon Musk’s SpaceX is preparing to further test its Starlink satellite internet in a demonstration for the U.S. Air Force, the company revealed in a recent request to the Federal Communications Commission.

“SpaceX seeks to make minor modifications to its experimental authorization for additional test activities undertaken with the federal government,” the company wrote to the FCC in a filing on Thursday.

“The tests are designed to demonstrate the ability to transmit to and receive information from two stationary ground sites and one airborne aircraft at one location, and would add to these limited testing from a moving vehicle on the ground,” SpaceX said.

The new treatment utilizes “artificial brainwaves” through a wearable device that according to clinical trials, resulted in 77% of subjects recovering faster from strokes if compared to those not using the treatment. The “artificial brainwaves” are delivered via electromagnetic radiation, which stimulates the nervous system to regrow and heal itself. In using this method, BrainQ was able to imitate the processes of neural network synchronization.

In a study conducted by the company, using a double-blind randomized controlled trial, it was found that after eight weeks of treatment, 77% of test subjects receiving BrainQ’s therapy had scores of 1 or 0 on the modified rankin scale, which indicates that either no symptoms or minor symptoms resulted from the trial, along with no significant disability.

The results of the study is expected to be presented at the International Stroke Conference in late March.
