U.S. Space Force's Hyperspace Challenge, an innovation accelerator, has declared the commencement of its 2023 program. This endeavor, in collaboration with the Space Rapid Capabilities Office (Space RCO) of the U.S. Space Force, aims to bring together a pool of seasoned researchers and established firms. The objective of the 2023 cohort is to brainstorm novel strategies to enhance the resilience

One of the most basic assumptions of fundamental physics is that the different properties of mass - weight, inertia and gravitation - always remain the same in relation to each other. Without this equivalence, Einstein's theory of relativity would be contradicted and our current physics textbooks would have to be rewritten. Although all measurements to date confirm the equivalence principle, qua

The Earth is 4.5 billion years old, and, during that time, it has seen some things. Life has been a part of most of that history, but what life has looked like has changed dramatically over the eons. Deciphering how life worked on this planet during its different epochs is one of the things that Dalton Hardisty works on at Michigan State University. In fact, he's part of an internati

When a NASA spacecraft successfully knocked an asteroid off course last year it sent dozens of boulders skittering into space, images from the Hubble telescope showed on Thursday. NASA's fridge-sized DART probe smashed into the pyramid-sized, rugby ball-shaped asteroid Dimorphos roughly 11 million kilometres (6.8 million miles) from Earth in September last year. The spacecraft knocked th

New polling data released by the Pew Research Center indicates that Americans want the nation to maintain a continued presence in space. A sample group of 10,329 U.S. adults was surveyed between May 30 and June 4. About seven in 10 respondents said America's role in space was essential, while 30% said it was not. The survey indicates that 47% of Americans have done at leas

No, oxygen didn't catalyze the swift blossoming of Earth's first multicellular organisms. The result defies a 70-year-old assumption about what caused an explosion of oceanic fauna hundreds of millions of years ago. Between 685 and 800 million years ago, multicellular organisms began to appear in all of Earth's oceans during what's known as the Avalon explosion, a forerunner era of the mor
