Once you can accept the Universe as matter expanding into nothing that is something, wearing stripes with plaid comes easy.

NASA Astronaut Megan McArthur Retires

NASA News - Fri, 08/29/2025 - 11:21am
NASA astronaut and Expedition 65 Flight Engineer Megan McArthur removes Kidney Cells-02 hardware inside the Space Automated Bioproduct Laboratory and swaps media inside the Microgravity Science Glovebox. The human research study seeks to improve treatments for kidney stones and osteoporosis

NASA astronaut Megan McArthur has retired, concluding a career spanning more than two decades. A veteran of two spaceflights, McArthur logged 213 days in space, including being the first woman to pilot a SpaceX Dragon spacecraft and the last person to “touch” the Hubble Space Telescope with the space shuttle’s robotic arm.

McArthur launched as pilot of NASA’s SpaceX Crew-2 mission in April 2021, marking her second spaceflight and her first long-duration stay aboard the International Space Station. During the 200-day mission, she served as a flight engineer for Expeditions 65/66, conducting a wide array of scientific experiments in human health, materials sciences, and robotics to advance exploration of the Moon under Artemis and prepare to send American astronauts to Mars.

Her first spaceflight was STS-125 in 2009, aboard the space shuttle Atlantis, the fifth and final servicing mission to Hubble. As a mission specialist, she was responsible for capturing the telescope with the robotic arm, as well as supporting five spacewalks to update and repair Hubble after its first 19 years in space. She also played a key role in supporting shuttle operations during launch, rendezvous with the telescope, and landing.

“Megan’s thoughtful leadership, operational excellence, and deep commitment to science and exploration have made a lasting impact,” said Steve Koerner, acting director of NASA’s Johnson Space Center in Houston. “Her contributions have helped shape the future of human space exploration, and we are incredibly grateful for her service.”

In addition to her flight experience, McArthur has served in various technical and leadership roles within NASA. In 2019, she became the deputy division chief of the Astronaut Office, supporting astronaut training, development, and ongoing spaceflight operations. She also served as the assistant director of flight operations for the International Space Station Program starting in 2017.

Since 2022, McArthur has served as the chief science officer at Space Center Houston, NASA Johnson’s official visitor center. Continuing in this role, she actively promotes public engagement with space exploration themes, aiming to increase understanding of the benefits to humanity and enhance science literacy.

“Megan brought a unique combination of technical skill and compassion to everything she did,” said Joe Acaba, chief of the Astronaut Office at NASA Johnson. “Whether in space or on the ground, she embodied the best of what it means to be an astronaut and a teammate. Her contributions will be felt by the next generation of explorers she helped train.”

McArthur was born in Honolulu and raised as a “Navy kid” in many different locations worldwide. She earned a Bachelor of Science in aerospace engineering from the University of California, Los Angeles, and a doctorate in oceanography from the Scripps Institution of Oceanography at the University of California, San Diego. Before being selected as an astronaut in 2000, she conducted oceanographic research focusing on underwater acoustics, which involved shipboard work and extensive scuba diving.

McArthur is married to former NASA astronaut Robert Behnken, who also flew aboard the Dragon Endeavour spacecraft during the agency’s SpaceX Demo-2 mission in 2020.

“It was an incredible privilege to serve as a NASA astronaut, working with scientists from around the world on cutting-edge research that continues to have a lasting impact here on Earth and prepares humanity for future exploration at the Moon and Mars,” said McArthur. “From NASA’s Hubble Space Telescope to the International Space Station, our research lab in low Earth orbit, humanity has developed incredible tools that help us answer important scientific questions, solve complex engineering challenges, and gain a deeper understanding of our place in the universe. Seeing our beautiful planet from space makes it so clear how fragile and precious our home is, and how vital it is that we protect it. I am grateful I had the opportunity to contribute to this work, and I’m excited to watch our brilliant engineers and scientists at NASA conquer new challenges and pursue further scientific discoveries for the benefit of all.”

Landsat 9 Sees Buccaneer Archipelago

NASA Image of the Day - Fri, 08/29/2025 - 11:09am
In the sparsely populated Kimberley region of Western Australia, jagged landforms reach like fingers into the turquoise-blue ocean waters. Along the coastline north of Derby, they used to reach even farther. But rising sea levels submerged part of the coastal landscape, giving rise to hundreds of islands and low-lying reefs that compose the Buccaneer Archipelago.

The Operational Land Imager on Landsat 9 captured this image of Buccaneer Archipelago on June 11, 2025. The scene encapsulates the striking interactions between land and water in the area where King Sound opens to the Indian Ocean.

The powerful tidal currents stir up sediment in shallow areas, producing the beautiful turquoise swirls visible in this image. This power, however, can be hazardous to seafarers and divers as water rips through the archipelago’s constricted passages. One infamous place of turbulence, known as “Hell’s Gate,” lies in the passage between Gerald Peninsula and Muddle Islands.
