SpaceX Dragon capsule carrying private Ax-2 astronauts splashes down off Florida coast (video)

Posted by in category: space travel

The four astronauts of the private Ax-2 mission returned to Earth in their SpaceX Dragon capsule late Tuesday night (May 30).

That Dragon, named Freedom, undocked from the International Space Station (ISS) earlier in the day at 11:05 a.m. EDT (1505 GMT), ending a 10-day mission that included eight days docked at the orbiting lab. Freedom returned to Earth 12 hours later with a flawless splashdown in the Gulf of Mexico off the coast of Panama City, Florida at 11:04 p.m. EDT (0304 GMT on May 31), ending the Ax-2 mission by SpaceX for the Houston-based company Axiom Space.

US urged not to use bomb-grade uranium in nuclear power experiment

Posted by in categories: climatology, nuclear energy, sustainability

WASHINGTON, May 30 (Reuters) — Former U.S. State Department and nuclear regulatory officials on Tuesday urged the U.S. Energy Department to reconsider a plan to use bomb-grade uranium in a nuclear power experiment, saying that its use could encourage such tests in other countries.

The Energy Department and two companies aim to share costs on the Molten Chloride Reactor Experiment (MCRE) at the Idaho National Laboratory and use more than 1,322 pounds (600 kg) of fuel containing 93% enriched uranium.

Bill Gates-backed company TerraPower LLC, the utility Southern Co (SO.N) and the department hope the six-month experiment will lead to breakthroughs in reactors that could help reduce pollution linked to climate change.

Software offers new way to listen for signals from the stars

Posted by in categories: alien life, information science

The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS), led by Akshay Suresh, Cornell doctoral candidate in astronomy, is pioneering a search for periodic signals emanating from the core of our galaxy, the Milky Way. The research aims to detect repetitive patterns, a way to search for extraterrestrial intelligence (SETI) within our cosmic neighborhood.

The researchers developed software based on a Fast Folding Algorithm (FFA), an efficient search method offering enhanced sensitivity to periodic sequences of narrow pulses. Their paper, “A 4–8 GHz Galactic Center Search for Periodic Technosignatures,” was published May 30 in The Astronomical Journal.

Pulsars—rapidly rotating that sweep beams of radio energy across the Earth—are natural astrophysical objects that generate periodic signals but humans also use directed periodic transmissions for a variety of applications, including radar. Such signals would be a good way to get someone’s attention across , standing out from the background of non-periodic signals, as well as using much less energy than a transmitter that is broadcasting continuously.
