Plasma thrusters used on satellites could be much more powerful
Wednesday, 25 January 2023 04:26
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. Now, a new study from the University of Michigan suggests that smaller Hall thrusters can generate much more thrust-potentially making them candidates for interplanetary missions.

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.

NASA announced Thursday its new Mars Sample Receiving Project office, responsible for receiving and curating the first samples returned from the Red Planet, will be located at the agency's Johnson Space Center in Houston. The safe and rapid release of Mars samples after they return to Earth to laboratories worldwide for science investigations will be a priority.

The China National Space Administration on Saturday released a group of new photos from the country's lunar rover Yutu 2, together with its good wishes for all Chinese people, ahead of the Chinese New Year, the Year of the Rabbit.
The photos showed the wheel track left by the rover, some rocks and a small impact crater on the lunar surface.

Despite giving it the "old college try," Curiosity's attempt to drill into the Marker Band at the "Encanto" site did not reach sampling depth. Because other rocks around the rover look similar to "Encanto" and are likely also too hard to drill, the Science Team decided to convert the plan to a "Touch and Go."

Frozen molecules were central to the origin of life on Earth. In addition to impacts of icy comets and asteroids, according to current theory, our planet likely also received the elementary components of life from the ices of the immense interstellar molecular cloud from which the Earth and the rest of the solar system emerged.

Solar flares and other types of space weather can wreak havoc with spaceflight and with telecommunications and other types of satellites orbiting the Earth. But, to date, scientists' ability to research ways to overcome that challenge has been severely limited. That's because experiments they conduct in laboratories here on Earth are affected by gravity in ways that are so different from conditi Were galaxies much different in the early universe?

Spacecraft design expert discusses the viability of interstellar travel

Researchers at NASA recently announced the discovery of another planet about 95% the size of Earth that is 100 light-years away and could potentially sustain life.
Could this new discovery lead to humans one day traveling to planet TOI 700 e and enjoying its resources, such as the potential for liquid water? This is a question people may naturally ask, but they may not like the current answer.
"That is not going to happen in our lifetimes, but it is fascinating to discuss," says Dr.

It has been believed that Hall thrusters, an efficient kind of electric propulsion widely used in orbit, must be large to produce a lot of thrust. Now, a new study from the University of Michigan suggests that smaller Hall thrusters can generate much more thrust—potentially making them candidates for interplanetary missions.
"People had previously thought that you could only push a certain amount of current through a thruster area, which in turn translates directly into how much force or thrust you can generate per unit area," said Benjamin Jorns, U-M associate professor of aerospace engineering who led the new Hall thruster study to be presented at the AIAA SciTech Forum in National Harbor, Maryland, today.
