Notes from the Field

The H-IIA No. 23 rocket that will carry the GPM Core Observatory into space arrived at Tanegashima Space Center on Jan. 20, 2014. The rocket has two stages, a lower first stage that, with the help of two solid rocket boosters, gets it off the ground, and an upper second stage that lights up a […]

When a satellite gets to space, the first thing it needs to do is check in with those who sent it there. NASA’s David Lassiter is the guy on the other end of the line. “My job is just to make sure E.T. can call,” he said. Responsible for radio frequency communications– RF comms–he’ll be […]

At the town line into Minamitane on Tanegashima Island, Japan, a giant billboard announces, “Global Precipitation Measurement / Launching of the rocket is coming soon!” Six days to be exact. I grinned when I saw it. Global Precipitation Measurement, or GPM, is why I’m in town. The launch window begins at 1:07 p.m. Feb. 27 […]

Editor’s Note: This guest post was written by David Wolfe, a remote sensing specialist working with the Global Land Ice Measurements from Space (GLIMS) project, and Jeffrey Kargel, a professor at the University of Arizona and the GLIMS project coordinator. Wolfe wrote his thesis for Alaska Pacific University about glacier-dammed lakes in Alaska and recently […]

Editor’s Note: Jeffrey Kargel is a hydrologist at the University of Arizona and for the Global Land Ice Measurements from Space project. This is his account of the research he did during the aftermath of a deadly flash flood in Nepal’s Seti River Valley to determine its cause. You can read more about the event […]

The kitchen of the Sun Pearl hotel doesn’t have an oven. Most Japanese kitchen’s don’t, in fact, but Saturday morning, Nov. 30, the borrowed kitchen was in full swing. Cody Buell, systems administrator for the Global Precipitation Measurement mission’s team in Japan, chopped mushrooms that would go into the stuffing that Courtney Buell was stirring […]

How do you launch a satellite into space? It isn’t easy. The simple answer would be to build one, place it on a rocket, and shoot it off. But building and launching satellites turns out to be exceedingly complicated things to do. They’re highly complex machines, requiring profoundly precise levels of craftsmanship, not to mention […]

The choreography rivals precision aerial acrobats. The teamwork reflects the forward line of a pro football team. This is the vanguard of NASA’s mechanical engineering corps, and to experience them at their full operational power is to gain a profound appreciation for how much more goes into spaceflight than big, booming rockets. Ages range from […]

As a Digital Mapping System (DMS) operator, I have a fairly consistent morning ritual to prepare for a day of flying over the ice. This consistency is necessary for both operational integrity and presence of mind while we are attempting to accomplish our mission. I am often apprehensive at the beginning of a daily mission […]
