Beneath the Earth, ancient ocean floor likely surrounds the core
Tuesday, 11 April 2023 06:39
Through global-scale seismic imaging of Earth's interior, research led by The University of Alabama revealed a layer between the core and the mantle that is likely a dense, yet thin, sunk ocean floor, according to results published in Science Advances.
Seen only in isolated patches previously, the latest data suggests this layer of ancient ocean floor may cover the core-mantle boundary. Su Guiding JUICE to Jupiter
Tuesday, 11 April 2023 02:43
This phenomenal endeavour, led by the European Space Agency, is powered by Airbus technology. Our engineers have rarely faced a greater challenge than enabling such a journey. The JUICE probe will encounter extreme temperatures, intense radiation and decreasing solar energy during its 5 billion kilometre journey. Being self-sufficient in energy generation and storage is key to the mission's succ NASA study helps explain limit-breaking ultra-luminous x-ray sources

These objects are more than 100 times brighter than they should be. Observations by the agency's NuSTAR X-ray telescope support a possible solution to this puzzle.
Exotic cosmic objects known as ultra-luminous X-ray sources produce about 10 million times more energy than the Sun. They're so radiant, in fact, that they appear to surpass a physical boundary called the Eddington limit, which A Jovian journey to the icy worlds of a Gas Giant

On April 13, 2023, the European Space Agency is scheduled to launch a rocket carrying a spacecraft destined for Jupiter. The Jupiter Icy Moons Explorer - or JUICE - will spend at least three years on Jupiter's moons after it arrives in 2031. In October 2024, NASA is also planning to launch a robotic spacecraft named Europa Clipper to the Jovian moons, highlighting an increased interest in these Orion stretches its wings ahead of first crewed Artemis mission

Before NASA's Orion spacecraft for the Artemis II mission can be outfitted with its solar array wings, teams at the agency's Kennedy Space Center must first verify that the arrays extend and close properly. On March 17, 2023, technicians inside the Florida spaceport's Neil Armstrong Operations and Checkout Building unfurled one of the wings to confirm all mechanisms operate as expected.

Tuesday, 11 April 2023 02:43
Elon Musk's Twitter marked the BBC and NPR as "government-funded" on Saturday but has not applied the label to Tesla or SpaceX - which have received billions in subsidies.
Despite the significant contributions of federal and local governments to his businesses, Twitter this week decided to label NPR as "state-affiliated" media.

Heart experiments to help astronauts live better in space
Monday, 10 April 2023 15:13
Astronauts aboard the International Space Station are hard at work on research guided by students and researchers from the University of Colorado Boulder.
Two cardiovascular tissue experiments were launched to the ISS aboard SpaceX CRS-27 on March 15, 2023, and CU Boulder's BioServe Space Technologies developed the hardware for both. The research stems from National Institutes of Health grants led by Stanford University and Johns Hopkins University.
"When astronauts go to space it can have negative impact on their cardiovascular systems," said Stefanie Countryman, director of BioServe. "Our organs evolved to work here on Earth so they function differently in space. The goal with both of these projects is to better understand how these treatments impact cardiovascular issues in Earth bound people and to advance treatments that could be provided to astronauts before launch or while in space."
BioServe has been designing, building, and flying microgravity life science research experiments and hardware since 1987.

At least five ice ages have befallen Earth, including one 635 million years ago that created glaciers from pole to pole.
Called the Marinoan Ice Age, it's named for the part of Australia where geologic evidence was first collected in the 1970s.
Scientists say the Marinoan Ice Age was one of the most extreme in the planet's history, creating glacial ice that persisted for 15 million y Thule Air Base Gets New Name

Thule Air Base, the Department of Defense's northernmost installation, has been renamed to recognize Greenlandic cultural heritage and better reflect its role in the U.S. Space Force.
Following a ceremony held April 6, the installation is now known as Pituffik Space Base. Pituffik (pronounced bee-doo-FEEK) is the traditional Greenlandic name of the region where the base is located. The ren
