NASA's Laser Communications Relay Demonstration (LCRD) is gearing up for launch this fall, no earlier than Nov. 22. The payload arrived in Florida in May, fully integrated into its host spacecraft and ready for its final testing before being lofted into space.
LCRD will leverage the power of infrared light to send and receive information encoded into invisible laser beams from one location IU physicists lead world's most precise measurement of neutron lifetime

An international team of physicists led by researchers at Indiana University has announced the world's most precise measurement of the neutron's lifetime.
The scientific purpose of the experiment, which IU has led for over a decade, is to measure how long, on average, a free neutron lives outside the confines of atomic nuclei.

The first lunar rocks brought back to Earth in decades show the Moon was volcanically active more recently than previously thought, Chinese scientists said Tuesday.
A Chinese spacecraft carried lunar rocks and soil to Earth last year - humanity's first mission in four decades to collect samples from the Moon, and a milestone for Beijing's growing space programme.

A Dunlap Institute astronomer has discovered that our solar system may be surrounded by what she describes as a magnetic tunnel that can be seen in radio waves.
Dr. Jennifer West, Research Associate at the Dunlap Institute for Astronomy and Astrophysics, is making a scientific case that two bright structures that are seen on opposite sides of the sky - previously considered to be separate Russian film crew says shooting in space a 'huge challenge'

White House Press Secretary Jen Psaki on Monday declined to comment on a report claiming that China tested a nuclear-capable hypersonic missile in August.
"I'm not going to comment on the specific report," Psaki said when asked if she could confirm the report that China tested a nuclear-capable hypersonic missile this summer that surprised US officials.
Psaki reiterated Defense Secre Uncovering the secrets of ultra-low frequency gravitational waves

New methods of detecting ultra-low frequency gravitational waves can be combined with other, less sensitive measurements to deliver fresh insights into the early development of our universe, according to researchers at the University of Birmingham.
Gravitational waves - ripples in the fabric of Einstein's spacetime - that cross the universe at the speed of light have all sorts of wavelengt Hear sounds from Mars captured by Perseverance Rover

Thanks to two microphones aboard NASA's Perseverance rover, the mission has recorded nearly five hours of Martian wind gusts, rover wheels crunching over gravel, and motors whirring as the spacecraft moves its arm. These sounds allow scientists and engineers to experience the Red Planet in new ways - and everyone is invited to listen in.

Astronomers at Queen's University Belfast have launched a new online initiative, calling for volunteers to come forward and help to search for extrasolar planets.
The online citizen project, hosted by Zooniverse.org, Planet Hunters Next-Generation Transit Search (NGTS), is enlisting the help of the public to examine five years' worth of digital footage showing some of the brightest stars i Astronomers see white dwarf switch on and off

White dwarfs are what most stars become after burning off the hydrogen that fuels them. Now our astronomers have seen one of these galactic objects switching on and off for the first time.
Researchers used a planet-hunting satellite to observe the unique phenomenon in a white dwarf about 1,400 light years from Earth.
This particular white dwarf is known to be accreting, or feeding, f Dwarf galaxy catches globular cluster

Astronomers already knew that our own Milky Way grew by taking in smaller galaxies. But now a team of Italian-Dutch researchers have shown that a small galaxy neighbouring the Milky Way has in turn absorbed an even smaller galaxy from its vicinity. The researchers will publish their findings on Monday in the journal Nature Astronomy.

ESA’s latest CubeSat mission is destined to never leave the ground. Instead it is doing its duty as an opened-out ‘FlatSat’ – with its interlinked subsystems spread out across a table at the Agency’s Data Systems and Microelectronics Laboratory at its ESTEC technical centre in the Netherlands.

Auroras make for great Halloween décor over Earth, though ESA astronaut Thomas Pesquet snapped these green smoky swirls of plasma from the International Space Station in August. Also pictured are the Soyuz MS-18 “Yuri Gagarin” (left) and the new Nauka module (right).
The Station saw quite some aurora activity that month, caused by solar particles colliding with Earth’s atmosphere and producing a stunning light show.

Boeing aims for unmanned Starliner test flight in first half of 2022

Boeing is aiming for a test flight of its unmanned CST-100 Starliner capsule in the first half of next year and a potential launch of its crewed spacecraft at the end of 2022, company officials said Tuesday.
The CST-100 had been scheduled to fly to the International Space Station (ISS) from Cape Canaveral, Florida, on August 3 but the flight was aborted just hours before launch because of problems with propulsion system valves.
Boeing officials told reporters in a briefing on Tuesday that they were still conducting testing of the valves but they may heve become stuck because of moisture or condensation.
"Normal environment humidity was likely the source of that moisture in the valves," Michelle Parker, Boeing Space and Launch chief engineer, said.
