A 1,800 ft blade of volcanic rock piercing the Pacific Ocean. This is Ball’s Pyramid: the tallest volcanic sea stack on Earth. For decades, extreme climbers risked their lives trying to conquer its crumbling, near-vertical walls. But during those dangerous expeditions in the 1960s, they stumbled upon something impossible - 🧵/1

Four crew members from three space agencies will launch to the @Space_Station no earlier than spring 2027 for a long-duration science expedition as part of NASA’s SpaceX Crew-14 mission. NASA astronauts Kayla Barron and Chris Birch will serve as spacecraft commander and pilot, with JAXA (Japan Aerospace Exploration Agency) astronaut Makoto Suwa, and Roscosmos cosmonaut Arutyun Kiviryan as mission specialists Learn more:

Many have asked how this photo was made. This is my explanation. The ISS rotates about its pitch axis as it orbits Earth at 17,000mph to keep its nadir view constant. Because of this long exposure photography turns stars into arced lines. Sidereal clock drives on Earth match the planet's rotation to see stars clearly. I knew one designed for space could do this too. So a camera mount was custom built at @RITtigers to rotate once every 90 minutes using a 60 to 90 toothed gear system, cancelling out the orbital motion of ISS and allowing the capture of distant stars as fixed points! In essence, it is a a rotational coil spring powered analog star tracker. It was machined out of aluminum and is entirely mechanical to bypass NASA's strict electrical requirements for cargo. We had to get creative! After Expedition 72 it was safely returned to Earth and is to be displayed at RIT. Which I am pleased to say because a similar barn door tracker I made from spare parts on Expedition 6 for nighttime city photography was destroyed in an atmospheric trash disposal! Photography is an important part of sharing the journey to new frontiers for all people of Earth!

Expedition 74 crew members Chris Williams of @NASA and Sergey Kud‑Sverchkov and Sergei Mikaev, both from Roscosmos, returned to Earth aboard the Soyuz MS‑28 spacecraft in Kazakhstan on Sunday, July 26, 2026. More...

The American West never misses. In 1805, the Lewis and Clark Expedition crossed the Continental Divide at Lemhi Pass in Idaho, a landscape and travel route known to indigenous people for generations. Today, the landscape is part of the Lewis and Clark National Historic Trail, and sunsets still put on one heck of a show.
