7 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Juvenile black, white, and yellow-striped Bluehead wrasse fish dart in and out of a dead colony of pillar coral (Dendrogyra cylindrus), now covered in various algae, in the waters of Playa Melones, Puerto Rico. NASA Ames/Milan Loiacono Coral reefs cover only 1% of the ocean floor, but support an estimated 25% of all marine life in the ocean, earning them the moniker ‘rainforest of the sea.’ They also play a critical role for coastal communities; preventing coastal erosion, protecting…

Solar Cycle 25 is still in max phase, so more aurora-boosting sun storms could be coming

NeRD

You could get more opportunities to see supercharged auroras over the next few months, thanks to our very active sun. Solar activity waxes and wanes on an 11-year cycle. The current cycle, known as Solar Cycle 25, began in December 2019 and is still in its maximum phase, experts say. “Currently, we’re about two years into the maximum period, so we’re anticipating another year or so of maximum phase before we really enter the declining phase, which will lead us back to solar minimum,” Lisa Upton, co-chair of the Solar…

Station Science Top News: Oct. 11, 2024

NeRD

Researchers verified that 3D micro-computed tomography scans can map the orientation of plant roots in space and used the method to demonstrate that carrots grown in actual and simulated microgravity both had random root orientation. These findings suggest that simulated microgravity offers a reliable and more affordable tool for studying plant adaptation to spaceflight. MULTI-TROP evaluated the role of gravity and other factors on plant growth. Plant roots grow downward in response to gravity on Earth, but in random directions in microgravity, which is a challenge for developing plant growth facilities for space. Results…

Nuclear rockets could travel to Mars in half the time − but designing the reactors that would power them isn’t easy

NeRD

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. Dan Kotlyar is an Associate Professor of Nuclear and Radiological Engineering at the Georgia Institute of Technology. NASA plans to send crewed missions to Mars over the next decade – but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip. This relatively long transit time is a result of the use of traditional chemical rocket fuel. An alternative technology to the chemically propelled rockets…

Estonia joins Artemis Accords as moon-exploration coalition agrees to continue outreach efforts

NeRD

MILAN — The nations signed up to the Artemis Accords are looking to spread the word on common principles and best practices on exploring outer space.  Estonia became the 45th country to sign up to the Accords just ahead of the International Astronautical Congress (IAC) here, which opened on Monday (Oct. 14). But engagement and enlargement efforts won’t stop there. The Artemis Accords — a set of statements that set out common principles, guidelines and best practices for exploration of the moon and beyond — had its third heads-of-agencies meeting…

Europa Clipper Begins Journey to Jupiter’s Icy Moon

NeRD

A SpaceX Falcon Heavy rocket carrying NASA’s Europa Clipper spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 12:06 p.m. EDT on Monday, Oct. 14, 2024. After launch, the spacecraft plans to fly by Mars in February 2025, then back by Earth in December 2026, using the gravity of each planet to increase its momentum. With help of these “gravity assists,” Europa Clipper will achieve the velocity needed to reach Jupiter in April 2030.

OpenET: Balancing Water Supply and Demand in the West

NeRD

15 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) At the end of 2022, 65 percent of the Western United States was in severe drought, the result of a two decades long mega drought in the Colorado River Basin that had captured headlines around the world.  However, it was flooding, not drought, that was making headlines when we began our research for this story about OpenET, a revolutionary new online platform geared towards helping farmers and water managers monitor and reduce water use in watersheds where supplies were…
