What feels like up may actually be some other direction depending on how our brains process our orientation, according to psychology researchers at York University's Faculty of Health.
In a new study published in PLoS One, researchers at York University's Centre for Vision Research found that an individual's interpretation of the direction of gravity can be altered by how their brain respo Airbus signs multi-satellite contract with Intelsat for OneSat flexible satellites

As NASA prepares to send astronauts back to the Moon and on to Mars, the agency's quest to seek answers about our solar system and beyond continues to inform those efforts and generate new discoveries. The agency has extended the missions of two spacecraft, following an external review of their scientific productivity.

SpaceX successfully launched a Turkish communications satellite, the Turksat 5A, from Florida on Thursday night. Liftoff occurred at 9:15 p.m. aboard a Falcon 9 rocket from Complex 40 at Cape Canaveral Space Force Station, which was about 45 minutes later than SpaceX had originally scheduled for the launch though well within its four-hour launch window.

JOHANNESBURG — The European Space Agency (ESA) signed a nearly €296 million ($362 million) contract with Thales Alenia Space Jan. 7 to build a European module for NASA’s lunar Gateway space station.
The European System Providing Refueling, Infrastructure and Telecommunications (ESPRIT) module will provide communications and refueling capabilities to Gateway, a planned space station in orbit around the moon intended to support crewed missions to the lunar surface.
Evidence of water movement found in meteorites that only recently fell to Earth
Thursday, 07 January 2021 15:20 Write a comment
A team of researchers affiliated with institutions in Australia, the U.S. and France has found evidence of relatively recent water movement in meteorites that only recently collided with the Earth. In their paper published in the journal Science, the group describes their study of carbonaceous chondrite (CC) meteorites that landed on the surface of the Earth within the past century and what they found.
A lot of scientists believe that the water present on Earth came from meteorites. This theory has been difficult to prove because the meteorites recovered to date do not contain water and because chemical reactions that might have involved comet-borne water occurred millions of years ago. In this new effort, the researchers took a look at the idea from another angle—they studied isotopes in meteorites that have landed on Earth over just the past century.
Prior research has suggested that most, if not all, CC meteorites were formed approximately 4.5 billion years ago as part of larger asteroids. To find out if recent arrivals might have evidence of a water history, the researchers looked at uranium and thorium distributions in samples—the former is water-soluble while the latter is not.
Pioneering a way to keep very small satellites in orbit
Thursday, 07 January 2021 15:01 Write a comment
A cubesat, largely built by undergraduate students and scheduled to launch on Sunday, will explore the feasibility of a new propulsion method that could enable very small satellites to move around Earth's orbit without carrying fuel. This could pave the way for tiny satellites that stay in orbit for long periods and operate in swarms, monitoring storms and natural disasters, for example.
A cubesat is about the size of a loaf of bread, designed to hitch a ride into space with a major mission. Cubesats are low-cost ways to test out new technologies or enable students to get hands-on experience with space exploration. MiTEE is scheduled to fly from the Mojave Air and Space Port on Virgin Orbit's Launch Demo 2.
While Earth's atmosphere is much thicker on the ground, a scattering of air particles stretch all the way up to low Earth orbit—the territory of about 60 percent of Earth-orbiting satellites. Small satellites are more strongly affected by the drag of the upper atmosphere than large satellites, slowing their orbits and causing them to drop toward the Earth.
"These smaller spacecraft just don't last very long, maybe even days to weeks, or a few months, dependent upon how high they are," said Brian Gilchrist, a professor of electrical engineering and computer science, who supervised the team.
