Researchers working with the 500-Meter FAST telescope in China reported 1,652 fast radio bursts in 47 days coming from a single source.

The energetic phenomena known as Fast Radio Bursts (FRBs) are one of the greatest cosmic mysteries today. These mysterious flashes of light are visible in the radio wave part of the spectrum and usually last only a few milliseconds before fading away forever. Since the first FRB was observed in 2,007 astronomers have looked forward to the day when instruments of sufficient sensitivity would be able to detect them regularly.

That day has arrived with the completion of the 500-Meter FAST Radio Telescope (aka. Tianyan, “Eye of Heaven”). Since it commenced operations, this observatory has vastly expanded the number of detected FRBs. In fact, according to research led by the National Astronomical Observatories of the Chinese Academy of Sciences (NAO/CAS), the observatory detected a total of 1,652 independent bursts from a single source in 47 days.

The research, which recently appeared in the journal Science, was conducted by researchers from the Commensal Radio Astronomy FAST Survey (CRAFTS) project. CRAFTS includes researchers from the Cornell Center for Astrophysics and Planetary Science, the Max-Planck-Institut für Radioastronomie, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), and multiple universities in China, Australia, and the U.S.

Scientists at the University of Chicago say that they’ve successfully created a “strange” new state of matter in the laboratory called “superionic ice” — and that the stuff might already exist inside planets in our solar system.

“It was a surprise — everyone thought this phase wouldn’t appear until you are at much higher pressures than where we first find it,” co-author and University of Chicago researcher Vitali Prakapenka said in a press blurb. “But we were able to very accurately map the properties of this new ice, which constitutes a new phase of matter, thanks to several powerful tools.”

Prakapenka’s team used a particle acclerator to fire electons between two pieces of diamond, creating unfathomable pressures of 20 gigapascals in a sample of water and causing it to form an entirely new structure that reverted when they relieved the pressure.

Title: A data analysis of the first hermetic seal of SAM–a hi-fidelity, hybrid physicochemical and bioregenerative human habitat analog at the Biosphere 2

Track Code: AM-8

Abstract:
SAM is a Space Analog for the Moon and Mars. This hi-fidelity, hermetically sealed habitat analog and research center is composed of a living quarters for four crew, workshop, dual airlocks, and greenhouse with temperature, humidity, and carbon dioxide level controls. SAM incorporates a half acre indoor/outdoor Mars yard with scaled crater, synthetic lava tube, and gravity offset rig for use in sealed pressure suits. SAM leverages the world class expertise and facilities at the University of Arizona’s Biosphere 2 and the Controlled Environment Agriculture Center (CEAC). As with other analogs, SAM welcomes research teams from around the world in an effort to inform near-future, long-duration human habitation of the Moon and Mars. With the close of June 2,021 a six months refurbishing of the 1987 prototype for the Biosphere 2 Test Module was completed. A crew of five were sealed inside for four hours. This was the first hermetic seal of this iconic vessel in three decades. The paper summarizes the data and findings pertaining to this closure, with review of the internal atmospheric pressure, CO2, O2, humidity and temperature data, including the effect of activation of a CO2 scrubber built by Paragon SDC for NASA.

NASA has released a new video that imagines future human explorers and space tourists.

Robotic missions have toured much of our Solar System – but so far, the only place beyond Earth where humans have stood is the Moon. That may change in the coming decades, with space agencies vying to achieve the historic milestone of putting the first astronaut on Mars. Towards the end of this century, as the cost of launching into space is reduced to a few cents per kilogram, space tourism may become as cheap as a transatlantic flight today. New forms of space propulsion in the 22nd century and beyond may open up the stars to human settlement.

In this short film, NASA has visualised some of the distant places that lie waiting to be explored. We get a glimpse of people on the Red Planet, standing in a cloud city on Venus, drifting towards the water plumes of Enceladus, and even kayaking on Titan. We are then provided with scientifically accurate depictions of exoplanets that humans may visit in the more distant future.

Built for critical research, continuous LEO presence, and space tourism.

Nanoracks, Voyager Space, and Lockheed Martin just announced that they aim to launch the first-ever free-flying commercial space station into low Earth orbit (LEO) by 2027 as part of a collaboration with NASA, a press statement reveals.

The space station, called Starlab, will be used for conducting critical research, ensuring continuous U.S. presence in low Earth orbit, and also for “tourism and other commercial and business activities,” Lockheed Martin explains. The fact that the space station is free-flying means that it will not be locked into one orbital position.

That layer would be absolutely essential in trying to defend against a FOBS, that is if a defense at all is actually feasible or even strategically sound. We are not talking about a rogue state here with a few advanced ballistic missiles. China would be able to deploy dozens or even hundreds of these at once. At a certain point, kinetic defenses against such a capability become a losing proposition and a very costly one at that.

Still, this was an early test aboard a full-on rocket used for traditional space access missions. It will take China some time to perfect such a system and package it in a quickly deployable militarized configuration. Major thermal and ablative issues also must be overcome, among others, but it’s not like China hasn’t been working diligently in the hypersonic boost-glide vehicle realm for many years.

Regardless, if this report ends up being fully accurate, one thing is likely: New calls for hugely expensive missile defense capabilities will be ringing loud and often on Capitol Hill, as well as demands to do whatever possible to bring China to the bargaining table in hopes of obtaining some type of strategic arms limitation treaty.

Such planetary smashups are likely common in young solar systems, but they haven’t been directly observed.

Young planetary systems generally experience extreme growing pains, as infant bodies collide and fuse to form progressively larger planets. In our own solar system, the Earth and moon are thought to be products of this type of giant impact. Astronomers surmise that such smashups should be commonplace in early systems, but they have been difficult to observe around other stars.

Now astronomers at MIT, the National University of Ireland Galway, Cambridge University, and elsewhere have discovered evidence of a giant impact that occurred in a nearby star system, just 95 light years from Earth. The star, named HD 172,555 is about 23 million years old, and scientists have suspected that its dust bears traces of a recent collision.

The MIT-led team has observed further evidence of a giant impact around the star. They determined that the collision likely occurred between a roughly Earth-sized terrestrial planet and a smaller impactor at least 200,000 years ago, at speeds of 10 kilometers per second, or more than 22,000 miles per hour.
