By Eric Lindstrom What do Leonhard Euler (1707-1783) and Joseph-Louis Lagrange (1736-1813)  have to do with SPURS-2? How do we have two experiments going on simultaneously honoring the work of these famous mathematicians? Two frames of reference have taken their names from these 18th century mathematicians. In science, including oceanography, when we make measurements of […]

SpaceX (SpX)-9 Release: Following the unberth of Dragon yesterday afternoon, the crew used the Space Station Remote Manipulator System (SSRMS) to release Dragon at 5:11 AM Central Time for its return to Earth.  The Dragon capsule executed a de-orbit burn shortly after 10 AM Central Time, and splashed down in the Pacific Ocean approximately 45 …

SpaceX’s Dragon cargo craft splashed down in the Pacific Ocean at 11:47 a.m. EDT, approximately 326 miles west of Baja California, marking the end of the company’s ninth contracted cargo resupply mission to the International Space Station for NASA. Following splashdown, Dragon will be recovered from the ocean and put on a ship for transportation …

As the first phase of the ATom project draws to a close, I am still surprised at just how far the influence of land, and fires in particular, can travel through the atmosphere. Most of the time, the influence of land (and pollution that people generate) can only be seen a few miles from shore. […]

The SpaceX Dragon cargo spacecraft was released from the International Space Station’s robotic arm at 6:11 a.m. EDT. The capsule will begin a series of departure burns and maneuvers to move beyond the 656-foot (200-meter) “keep out sphere” around the station for its return trip to Earth. The capsule is currently scheduled to splashdown in …

NASA Television will provide live coverage of the departure of the SpaceX Dragon spacecraft from the International Space Station beginning at 5:45 a.m. EDT. Dragon was detached from the Earth-facing side of the station’s Harmony module last night by robotics controllers who maneuvered Dragon into place for its release under the control of and Expedition …

The ATom mission is the first to traverse the whole lengths of the Atlantic and Pacific Oceans while making atmospheric measurements from the ocean surface to high altitudes. When we planned ATom, one idea was to compare pollution impacts between the oceans. I expected that human activities would have much greater influence in the Atlantic, […]

SpaceX (SpX)-9 Unberth: The crew packed critical items and egressed the vehicle in preparation for Dragon departure.  Dragon was unberthed from the ISS via ground commanding at 4 PM CDT today. The vehicle will be maneuvered via ground commanding to an overnight park position in preparation for release tomorrow at 5:11 AM CDT with splashdown …

The booster and Centaur upper stage of a United Launch Alliance Atlas V vent gaseous propellant during a “wet dress rehearsal” test at Space Launch Complex 41 on Florida’s Cape Canaveral Air Force Station. The rocket will boost NASA’s OSIRIS-REx spacecraft on its way to the asteroid Bennu. Short for Origins, Spectral Interpretation, Resource Identification, …

“Thousands of tired, nerve-shaken, over-civilized people are beginning to find out that going to the mountains is going home; that wildness is a necessity” ― John Muir, Our National Parks Happy Birthday to the U.S. National Park Service! A century after President Woodrow Wilson signed the bill that established the National Park Service, there are […]
