Study quantifies global impact of electricity in dust storms on Mars
Mars is infamous for its intense dust storms, some of which kick up enough dust to be seen by telescopes on Earth.
When dust particles rub against each other, as they do in Martian dust storms, they can become electrified, transferring positive and negative electric charge in the same way as you build up static electricity if you shuffle across a carpet.
Strong electric fields build Biology and Robotics Research Occupy Crew
A multitude of advanced microgravity research benefitting humans and robotics took precedence aboard the International Space Station on Thursday.
Two Expedition 68 astronauts investigated how living in space affects the way a crew member reaches for and grasps objects. NASA Flight Engineer Josh Cassada has been working in the Columbus laboratory module all week exploring how spaceflight im Japan's H3 rocket fails to leave the launch pad
Another setback for Japan Aerospace Exploration Agency (JAXA). Japan's H3 rocket was scheduled to lift off from Tanegashima Space Center, Japan at 10:37 a.m. Japan Standard Time on February 17th.
It was supposed to launch Advanced Land Observing Satellite-3 (ALOS-3), also known as Daichi-3 into a Sun-synchronous orbit (SSO). ALOS-3 is an advanced, Earth observing satellite, to be used for An extremely lightweight fission rocket could reach the solar gravitational lens in 15 years
Novel propulsion ideas for moving around space seem like they're a dime a dozen recently. Besides the typical argument between solar sails and chemical propulsion lies a potential third way—a nuclear rocket engine. While we've discussed them here at UT before, NASA's Institute of Advanced Concepts has provided a grant to a company called Positron Dynamics for the development of a novel type of nuclear fission fragment rocket engine (FFRE). It could strike the balance between the horsepower of chemical engines and the longevity of solar sails.
FFREs are not a new concept in themselves, but many have massive technical hurdles to overcome before they can be considered useful. Their advantages, such as high specific impulse and extremely high power density, are offset by their disadvantages, such as requiring a complicated form of plasma levitation.
What is a UFO? The US shot down three mysterious objects as interest and concern increase over unidentified craft
On the heels of the Feb. 4, 2023, shooting down of a Chinese balloon suspected of spying on the U.S., American fighter jets have shot down three additional objects in or near U.S. airspace.
When the media asked Glen VanHerck, the Air Force general responsible for overseeing North American airspace, about these events, he refused to rule out extraterrestrial forces at play. Other military officialslater clarified that otherworldly origins aren't a serious consideration, but the comment highlighted the U.S. government's lack of knowledge about these objects.
As a space policy expert, I'm often confronted with questions about UFOs and little green people. However, as these recent episodes have shown, a UFO is far more likely to be human-made, rather than originating from some faraway place in the universe.
Webb reveals intricate networks of gas and dust in nearby galaxies
Researchers using the NASA/ESA/CSA James Webb Space Telescope are getting their first look at star formation, gas, and dust in nearby galaxies with unprecedented resolution at infrared wavelengths. The data have enabled an initial collection of 21 research papers which provide new insight into how some of the smallest-scale processes in the Universe — the beginnings of star formation — impact the evolution of the largest objects in our cosmos: galaxies.

China will employ BeiDou satellite-based augmentation system (BDSBAS) to provide high-precision positioning service in railway survey and construction, according to the China Railway Siyuan Survey and Design Group Co., Ltd.
Four satellite-based and 12 ground-based observation stations will be set up along the Wufeng-Enshi railway section in central China's Hubei Province.
