Are the space junk and carbon footprint issues of extra-terrestrial endeavours solvable?
Summary: Too much salt can disrupt the energy balance of immune cells and prevent them from functioning correctly.

For many of us, adding salt to a meal is a perfectly normal thing to do. We don’t really think about it. But actually, we should. As well as raising our blood pressure, too much salt can severely disrupt the energy balance in immune cells and stop them from working properly.
An invention from Purdue University innovators may provide a new option to use directed energy for biomedical and defense applications.
The Purdue invention uses composite-based nonlinear transmission lines (NLTLs) for a complete high-power microwave system, eliminating the need for multiple auxiliary systems. The interest in NLTLs has increased in the past few decades because they offer an effective solid-state alternative to conventional vacuum-based, high-power microwave generators that require large and expensive external systems, such as cryogenic electromagnets and high-voltage nanosecond pulse generators.
NLTLs have proven effective for applications in the defense and biomedical fields. They create directed high-power microwaves that can be used to disrupt or destroy adversary electronic equipment at a distance. The same technology also can be used for biomedical devices for sterilization and noninvasive medical treatments.

Scientists around the world have been bamboozled this week by a fictitious asteroid heading toward Earth.
A group of experts from US and European space agencies attended a week-long exercise led by NASA in which they faced a hypothetical scenario: An asteroid 35 million miles away was approaching the planet and could hit within six months.
For the first time, scientists have been able to precisely map the flight path of an asteroid that landed on Earth and trace it back to its point of origin. The boulder-size fragment’s journey to our planet began 22 million years ago, according to new research.
The asteroid, known as 2018 LA, appeared like a fireball in the skies over Botswana on June 2, 2018, before breaking apart and landing in the Central Kalahari Game Reserve.
Prior to breaking up in Earth’s atmosphere, scientists determined that the asteroid was about 5 feet (1.7 meters) in diameter, weighed 12566 pounds and had been traveling at 37282 miles per hour.
Just days after Earth was hit by a coronal mass ejection (CME), it appears another blast of solar wind is due to impact Earth on Sunday; it is currently traveling at a brisk 1118, 468 mph towards the planet.
A minor G1-class Geomagnetic Storm is possible late Saturday into much of Sunday as the solar wind interacts with the Earth’s magnetic field. While the National Weather Service’s Space Weather Prediction Center has not issued any advisory for this solar wind yet, a watch or warning could be posted tomorrow for this event.
An international collaboration of astronomers led by a researcher from the Astrobiology Center and Queen’s University Belfast, and including researchers from Trinity, has detected a new chemical signature in the atmosphere of an extrasolar planet (a planet that orbits a star other than our Sun).
Crew-1 Mission | Return
Posted in robotics/AI, space travel
SpaceX and NASA are targeting Saturday, May 1 at 8:35 p.m. EDT, or 00:35 UTC on May 2, for Dragon to autonomously undock from the International Space Station (ISS) and splashdown off the coast of Florida on Sunday, May 2 at approximately 2:57 a.m. EDT, 6:57 UTC, completing its first six-month operational mission to the Station.
A series of departure burns will move Dragon away from the orbiting laboratory, followed by the vehicle jettisoning the trunk to reduce weight and mass to help save propellant for the deorbit burn. Once complete, Dragon will re-enter Earth’s atmosphere and deploy its two drogue and four main parachutes in preparation for a soft water landing.
Aboard the spacecraft will be NASA astronauts Mike Hopkins, Victor Glover, Shannon Walker, and JAXA astronaut Soichi Noguchi, who flew to the space station on Dragon six months ago when Falcon 9 launched the spacecraft from historic Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida on Sunday, November 15, 2020.
Upon splashdown, the Dragon and the astronauts will be quickly recovered and returned to Cape Canaveral and Houston respectively. Once the mission is complete, Dragon will be inspected and refurbished for future human spaceflight missions.
