The Fuss Over Phosphorus

Posted by in categories: biological, chemistry, climatology, particle physics, space

Phosphorus, the element critical for life´s origin and life on Earth, may be even Venus.


Scientists studying the origin of life in the universe often focus on a few critical elements, particularly carbon, hydrogen, and oxygen. But two new papers highlight the importance of phosphorus for biology: an assessment of where things stand with a recent claim about possible life in the clouds of Venus, and a look at how reduced phosphorus compounds produced by lightning might have been critical for life early in our own planet’s history.

First a little biochemistry: Phosphine is a reduced phosphorus compound with one phosphorus atom and three hydrogen atoms. Phosphorus is also found in its reduced form in the phosphide mineral schreibersite, in which the phosphorus atom binds to three metal atoms (either iron or nickel). In its reduced form, phosphorus is much more reactive and useful for life than is phosphate, where the phosphorus atom binds to four oxygen atoms. Phosphorus is also the element that is most enriched in biological molecules as compared to non-biological molecules, so it’s not a bad place to start when you’re hunting for life.

NASA’s rover makes breathable oxygen on Mars

Posted by in category: space

History has been made!!!

It made 5 grams of the gas — equivalent to what an astronaut at Mars would need to breathe for roughly 10 minutes.


An instrument in the Perseverance rover produces oxygen from the planet’s carbon dioxide atmosphere.

NASA’s Perseverance Rover Just Turned Martian CO2 Into Oxygen

Posted by in categories: space, sustainability

Oxygen isn’t just the stuff we breathe. Rocket propellant depends on oxygen, and future explorers will depend on producing propellant on Mars to make the trip home.


The instrument, called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE), is a technology demonstration that could eventually be scaled up to produce enough propellant to enable a crew of astronauts to take off from the surface of the Red Planet.

“This is a critical first step at converting carbon dioxide to oxygen on Mars,” said Jim Reuter, associate administrator of NASA’s Space Technology Mission Directorate (STMD), in a statement. “MOXIE has more work to do, but the results from this technology demonstration are full of promise as we move toward our goal of one day seeing humans on Mars.”

Da Vinci And Sikorsky Also Deserve Credit For NASA’s Mars Helicopter

Posted by in categories: space, sustainability

With NASA’s historic solar-powered helicopter flight over the barren slopes of Mars’ Jezero Crater, Leonardo da Vinci and Igor Sikorsky also deserve credit along with the Wright brothers for enabling this astounding bit of off-world powered, controlled flight. Da Vinci made one of the earliest drawings of a rotor-driven aircraft and Sikorsky built the U.S.’ first commercially viable helicopter.

Even though Orville and Wilbur Wright get credit for making the first powered, controlled aircraft flight at Kitty Hawk, North Carolina in 1903, the vertical flight of helicopters is markedly different. Thus, the first test flight of NASA’s Ingenuity helicopter is all the more astounding in no small part because Mars’ atmosphere is only one percent that of Earth.

“While these two iconic moments in aviation history may be separated by time and 173 million miles of space, they now will forever be linked,” NASA Associate Administrator for Science Thomas Zurbuchen said in a statement. “As an homage to the two innovative bicycle makers from Dayton, this first of many airfields on other worlds will now be known as Wright Brothers Field, in recognition of the ingenuity and innovation that continue to propel exploration.”

DARPA Nuke Sat To Target Cislunar Monitoring Mission

Posted by in categories: military, space

Beyond Cislunar

Indeed, AFRL last Thursday held a classified stakeholder meeting to discuss research and development needed to underpin future military operations beyond the traditional near-Earth orbits used today, according to DoD officials. Neither AFRL nor Space Command would provide any details whatsoever about the meeting — not even a list of participants.

Sean Kirkpatrick, who represents the DNI at Space Command’s Joint Task Force-Space Defense (JTF-SD), said last Tuesday the “summit” was focused not just on R&D needed to counter potential adversary activities in cislunar space, but also “all around the sphere of the Earth, not necessarily in the direction of the Moon.”

Want to work in the growing space industry? How one CEO says hiring needs to expand

Posted by in categories: business, engineering, government, mathematics, space

The growth of space businesses makes this “the most exciting time” to be involved in the industry, but one CEO says private and government organizations must do more to tap the next generation of U.S. workers.

“I do think there’s opportunities for everybody to participate in the excitement … [and] it’s a great opportunity for the government to really lean in on looking for those public-private partnerships,” Steve Isakowitz, CEO of The Aerospace Corporation and former president of Virgin Galactic, told attendees of the America’s Future Series Space Innovation Summit. The event ran on April 6 and 7.

“We need to do more and expand the candidate pool — we’ve got to make sure that all of America has the benefit of being part of the STEM, K-12, opportunities that are out there,” he added, referring to the academic discipline that includes science, tech, engineering and math.

Ultracold atom interferometry in space

Posted by in categories: particle physics, space

Conducting atom-optical experiments in space is interesting for fundamental physics and challenging due to different environment compared to ground. Here the authors report matter-wave interferometry in space using atomic BECs in a sounding rocket.

Mars helicopter flight test promises Wright Brothers moment for NASA

Posted by in categories: space, sustainability

NASA hopes to score a 21st-century Wright Brothers moment on Monday as it attempts to send a miniature helicopter buzzing over the surface of Mars in what would be the first powered, controlled flight of an aircraft on another planet.

Landmark achievements in science and technology can seem humble by conventional measurements. The Wright Brothers’ first controlled flight in the world of a motor-driven airplane, near Kitty Hawk, North Carolina, in 1903 covered just 120 feet (37 meters) in 12 seconds.

A modest debut is likewise in store for NASA’s twin-rotor, solar-powered helicopter Ingenuity.

Smartphones can detect huge solar storms

Posted by in categories: mobile phones, space

Massive solar storms in space can be picked up by iOS and Android smartphones, meaning billions of people have a personal geomagnetic storm detector — but the signals threaten to interfere with future location-based applications.

Hoping to get the public more involved in science, study author Sten F. Odenwald, an astronomer at the NASA Goddard Spaceflight Center, published a paper on the topic April 2 in Space Weather. It indicates that even through the unavoidable interference caused by other smartphone components, the phone’s built-in magnetometers can detect geomagnetic storms.

“Smartphones — at least theoretically — should be able to detect some of the strongest storms, pretty easily in fact,” Odenwald told The Academic Times. “Especially if you happen to live up in the northern latitudes — in Minnesota or in Canada, or places like that where it really rocks and rolls.”

Basically, we live in one giant algorithm.


In fascinating new research, cosmologists explain the history of the universe as one of self-teaching, autodidactic algorithms.
