Discovering chemical substances as possible chemical markers of life existence in Venus’s atmosphere via remote astronomical observations cannot be considered objective evidence of life existence on the planet, says Roscosmos Executive Director for Science and Advanced Programs Alexander Bloshenko. ‘Credible scientific data on that matter can be obtained only via contact explorations of the planet’s surface and atmosphere,’ he added.

Notably, the USSR was the only country to conduct regular explorations of Venus using on-planet stations. The first ever soft landing on another planet’s surface in the Solar system was performed in 1970 by the Venera-7 descent module. Several orbital missions and landings provided detailed data on the Venerian climate, soil and atmosphere composition. The Soviet Venera-13 spacecraft still holds the record as the longest active spacecraft on Venus remaining operational for 127 minutes.

A huge breakaway of the Soviet Union from its competitors in exploration of Venus contributed to the fact that USA called Venus a ‘Soviet planet’. Having recently analyzed the pictures of Venus captured by Soviet missions, scientists of the Russian Academy of Sciences claimed they discovered moving objects and even might be living. And it remains to be seen, whether these guesses are true.

Today, a program of complex exploration of Venus has been developed by Roscosmos in cooperation with the Russian Academy of Sciences. The program consists of several missions. Moreover, a decision was taken to implement the previously planned Venera-D mission including orbital and landing modules, as a national project without involving wide international cooperation. The complex explorations will also include soil and atmosphere samples, as well as exploring evolution processes on Venus that has purportedly suffered a climatic disaster connected with greenhouse effect that is much discussed on Earth today.

A SpaceX Falcon 9 rocket is about to carry what will soon become the International Space Station’s first privately-built airlock.

The company has previously built standardized boxes for space-based experiments and tiny satellite deployers, The Verge reports.

The Bishop is shaped like a bell jar and attaches itself to the outside of the space station using a number of clamps and latches.

“Once it’s there, it’s just extra real estate until we want to use it,” Mike Lewis, Nanoracks’ chief innovation officer, told The Verge. “We can use it in a number of ways, the first of which is to bring things outside.”

With today’s news of the first-ever detection of an intact planet closely orbiting a stellar white dwarf, a team led by two Cornell University astronomers has also shown that NASA’s forthcoming James Webb Space Telescope (JWST) would be capable of detecting biosignatures from earth-sized planets orbiting such dying stars.

As reported in the journal Nature, the white dwarf in question —- WD 1856+534 —- is now thought to harbor a Jupiter-size object orbiting this dying stellar core on an insanely short orbit of only 34 hours. But even before today’s announcement, Cornell astronomers were testing their idea that the Webb telescope might also be able to detect earth-sized objects within the same system.

In separate research submitted to The Astrophysical Journal Letters, Cornell University astronomers Lisa Kaltenegger and Ryan MacDonald and the paper’s 1st co-authors, lay out their case for using the Webb telescope to look for very short transits of such rocky worlds as they pass in front of the these white dwarfs. They used WD 1856+534, which is only 40 percent larger than Earth and lies only 80 lights years away in the constellation of Draco, as their test case.

A single infusion of an experimental drug markedly reduced levels of the coronavirus in newly infected patients and lowered the chances that they would need hospitalization, the drug’s maker announced on Wednesday.

The drug is a monoclonal antibody, a manufactured copy of an antibody produced by a patient who recovered from Covid-19, the illness caused by the coronavirus. Many scientists hope that monoclonal antibodies will prove to be powerful treatments for Covid-19, but they are difficult and expensive to manufacture, and progress has been slow.

A so-called monoclonal antibody lowered levels of the coronavirus and prevented hospitalizations. The research has not yet been vetted by independent experts.

Millions of space nerds reacted with joy Monday to a study showing the atmosphere of Venus contains phosphine, a chemical byproduct of biological life. But none would have been more thrilled or less surprised by the discovery than the late, great Carl Sagan — who said this day might come more than 50 years ago.

Now best remembered as the presenter of the most-viewed-ever PBS series Cosmos, the author of the book behind the movie Contact, and the guy who put gold disks of Earth music on NASA’s Voyager missions, Sagan actually got his start studying our closest two planets. He became an astronomer after being inspired as a kid by Edgar Rice Burroughs’ space fantasies, set on Mars and Venus.

‘Cosmos’ presenter Carl Sagan was one of the world’s top experts on Venus, and he saw first what scientists have just announced: possible life on Venus.

We’ve had impressive efforts, such as India planting 66 million trees in a day, but that was a large-scale event, which required organizing millions of volunteers. It would be difficult to recreate something like that on a regular basis.

Luckily, a former NASA engineer has developed drones that can plant 100,000 trees per day each.

Multiply that by 165 drones, and we could easily fill the 6-billion-tree gap we face each year.

Returning to the theme of what might be dubbed “UFO Realism” I would like to address a topic that exercises the minds of a lot of UFO conspiracy theorists, namely, reverse engineered alien technologies.

First, is there any evidence at all that any technology we currently have has any extraterrestrial element? For example, one famous claim by Colonel Corso is that much modern technology was derived from the Roswell Incident. To quote the Wikipedia entry the list includes “…particle beam devices, fiber optics, lasers, integrated circuit chips and Kevlar material”, not to mention the transistor itself.

The initial problem with these claims is twofold.

Sept. 9, 2020 By Tom Ward, Senior Vice President, Customer Product, Walmart.

Years ago, our founder Sam Walton famously said, “I have always been driven to buck the system, to innovate, to take things beyond where they’ve been.” It remains a guiding principle at Walmart to this day. From being an early pioneer of universal bar codes and electronic scanning cash registers to our work on autonomous vehicle delivery, we’re working to understand how these technologies can impact the future of our business and help us better serve our customers.

Our latest initiative has us exploring how drones can deliver items in a way that’s convenient, safe, and – you guessed it – fast. Today, we’re taking the next step in our exploration of on-demand delivery by announcing a new pilot with Flytrex, an end-to-end drone delivery company.

Modern construction is a precision endeavor. Builders must use components manufactured to meet specific standards — such as beams of a desired composition or rivets of a specific size. The building industry relies on manufacturers to create these components reliably and reproducibly in order to construct secure bridges and sound skyscrapers.

Now imagine construction at a smaller scale — less than 1/100th the thickness of a piece of paper. This is the nanoscale. It is the scale at which scientists are working to develop potentially groundbreaking technologies in fields like quantum computing. It is also a scale where traditional fabrication methods simply will not work. Our standard tools, even miniaturized, are too bulky and too corrosive to reproducibly manufacture components at the nanoscale.

Researchers at the University of Washington have developed a method that could make reproducible manufacturing at the nanoscale possible. The team adapted a light-based technology employed widely in biology — known as optical traps or optical tweezers — to operate in a water-free liquid environment of carbon-rich organic solvents, thereby enabling new potential applications.
