NASA’s Psyche Mission Continues Preparation for Launch in 2023
After a one-year delay to complete critical testing, the Psyche project is targeting an October 2023 launch. NASA's Psyche spacecraft is shown in a clean room on Dec. 8, 2022, at Astrotech Space Operations Facility near the agency's Kennedy Space Center in Florida. The spacecraft was powered on and connected to ground support equipment, enabling engineers and technicians to prepare it for launch in 2023.

Were galaxies much different in the early universe?
The HERA radio telescope consists of 350 dishes pointed upward to detect 21-centimeter emissions from the early universe. It is located in a radio-quiet region of the arid Karoo in South Africa. An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting "cosmic dawn" - the era after the Big Bang when stars first ignited and galaxies began to bloom.

Plasma thrusters used on satellites could be much more powerful
It was believed that running more propellant through a Hall thruster would wreck its efficiency, but new experiments suggest they might power a crewed mission to Mars Study: Operation and performance of a magnetically shielded hall thruster at ultrahigh current densities on xenon and krypton It was believed that Hall thrusters, an efficient kind of electric propulsion widely used in orbit, need to be large to produce a lot of thrust.

How did the Butterfly Nebula get its wings? It’s complicated
Planetary nebulae form when red giant stars expel their outermost layers as they run out of helium fuel - becoming hot, dense white dwarf stars that are roughly the size of Earth. The material that was shed, enriched in carbon, forms dazzling patterns as it is blown gently into the interstellar medium.

NASA Scientists and Satellites Make Sense of Earth’s Subtle Motions
What can hidden motions underground tell us about earthquakes, eruptions, and even climate change? NASA scientists are using data gathered 400 miles above Earth to find out. Creeping, rising, falling, slipping - some parts of Earth are in perpetual motion. The movements are usually too tiny for human senses to notice, but they offer clues about more significant changes happening inside volcanoes, along fault lines, and where tectonic plates meet and clash.

Shift to ultraviolet-driven chemistry in planet-forming disks marks beginning of late-stage planet formation
The chemistry of planet formation has fascinated researchers for decades because the chemical reservoir in protoplanetary discs-the dust and gas from which planets form-directly impacts planet composition and potential for life. Department of Astronomy suggests that chemistry in late-stage planet development is fueled by ultraviolet rays, rather than cosmic rays or X-rays, and this new understanding provides a chemical signature that helps researchers trace exoplanets back to their cosmic nurseries in the planet-forming disks.

Ian Hutchinson: A lifetime probing plasma, on Earth and in space
Investigating the solar wind flowing past Earth, the MIT has found solitary waves that might arise within fusion devices. Ordinary folks gazing at the night sky can readily spot Earth's close neighbors and the light of distant stars. But when Ian Hutchinson scans the cosmos, he takes in a great deal more.

ICYMI: 2022 research round up
Penguin feathers may be secret to effective anti-icing technology Ice buildup on powerlines and electric towers brought the northern US and southern Canada to a standstill during the Great Ice Storm of 1998, leaving many in the cold and dark for days and even weeks. Whether it is on wind turbines, electric towers, drones, or airplane wings, dealing with ice buildup typically depends on techniques that are time consuming, costly and use a lot of energy, along with various chemicals.

NASA Gets Unusually Close Glimpse of Black Hole Snacking on Star
Recent observations of a black hole devouring a wandering star may help scientists understand more complex black hole feeding behaviors. Multiple NASA telescopes recently observed a massive black hole tearing apart an unlucky star that wandered too close. Located about 250 million light-years from Earth in the center of another galaxy, it was the fifth-closest example of a black hole destroying a star ever observed.

NASA’s Perseverance Rover to Begin Building Martian Sample Depot
The 10 sample tubes being dropped on Mars' surface so they can be studied on Earth in the future carry an amazing diversity of Red Planet geology. In the coming days, NASA's Perseverance rover is expected to begin building the first sample depot on another world. This will mark a crucial milestone in the NASA-ESA (European Space Agency) Mars Sample Return campaign, which aims to bring Mars samples to Earth for closer study.

WEAVE spectrograph begins study of galaxy formation and evolution
LIFU's advantage comes from the large amount of information contained in each observation. Using small displacements of the pointer, the WEAVE spectrograph has produced, in two hours, spectra for 31,500 regions in and around these galaxies. The total light intensity of each of the fibres is used to form the image of the galaxies shown in the centre.
