Antarctic Sea Ice Near Historic Lows; Arctic Ice Continues Decline

Sea ice at both the top and bottom of the planet continued its decline in 2024. In the waters around Antarctica, ice coverage shrank to near-historic lows for the third year in a row. The recurring loss hints at a long-term shift in conditions in the Southern Ocean, likely resulting from global climate change, according […]

International Space Station Program Deputy Chief Scientist Meghan Everett

“Don’t be afraid to go after the things that you’re dreaming about that aren’t necessarily possible right now. We do things all the time now that were impossible 10 years ago! Figure out how to make the impossible possible, if it’s what you want to do. “One of my cornerstone pinnacles [is], ‘Show up to […]
