Roscosmos: US astronaut to return to Earth with Russian spacecraft

Russia’s space agency Roscosmos said it will bring a US astronaut back to Earth from the International Space Station at the end of this month, despite tensions between the two countries.

NASA astronaut Mark Vande Hei will return as planned on March 30 together with cosmonauts Anton Shkaplerov and Pyotr Dubrov in a Russian Soyuz space capsule, the agency said in Moscow on Monday.

“Roscosmos has never given partners any reason to doubt our reliability,” the agency said, adding that the safe operation of the space station is its top priority.

Hubble catches a cosmic illusion predicted by Einstein 86 years ago

Little did he know that we would one day have telescopes powerful enough to image distant galaxies.

“[Einstein] had a sense of the natural sublime.”

The first known image of an Einstein ring was captured in 1987 at the Very Large Array radio observatory in New Mexico. A little over a decade later, Hubble found the first complete one. Since then astronomers have found many more of Einstein Rings including this one, which Tommaso Treu’s group in the Department of Physics and Astronomy at the University of Californa, Los Angeles, produced with the Hubble.

Study highlights the potential of neuromorphic architectures to perform random walk computations

Over the past decade or so, many researchers worldwide have been trying to develop brain-inspired computer systems, also known as neuromorphic computing tools. The majority of these systems are currently used to run deep learning algorithms and other artificial intelligence (AI) tools.

Researchers at Sandia National Laboratories have recently conducted a study assessing the potential of neuromorphic architectures to perform a different type of computations, namely random walk computations. These are computations that involve a succession of random steps in the mathematical space. The team’s findings, published in Nature Electronics, suggest that neuromorphic architectures could be well-suited for implementing these computations and could thus reach beyond machine learning applications.

“Most past studies related to focused on cognitive applications, such as ,” James Bradley Aimone, one of the researchers who carried out the study, told TechXplore. “While we are also excited about that direction, we wanted to ask a different and complementary question: can neuromorphic computing excel at complex math tasks that our brains cannot really tackle?”

NASA opens sample taken from the Moon 50 years on

The Apollo missions to the Moon brought a total of 2,196 rock samples to Earth. But NASA has only just started opening one of the last ones, collected 50 years ago.

For all that time, some tubes were kept sealed so that they could be studied years later, with the help of the latest technical breakthroughs.

NASA knew “science and technology would evolve and allow scientists to study the material in new ways to address new questions in the future,” Lori Glaze, director of the Planetary Science Division at NASA Headquarters, said in a statement.
