By Eric Lindstrom The focus of SPURS-2 is the upper ocean and the fate of rainwater. However, in order to study the top of the ocean one needs to know what is going on deeper down. The beauty of SPURS-2 is not skin-deep! SPURS-2, like many prior physical oceanography experiments, requires a basic background and […]

Biomolecule Sequencer WIFI Reconnection and Sample Sequence Completion: Over the weekend the crew completed the deoxyribonucleic acid (DNA) sequencing process that began last week and transferred the screenshots to the Surface Pro 3 tablet for downlink. The Biomolecule Sequencer investigation seeks to demonstrate for the first time that DNA sequencing is feasible in an orbiting …
Crew Preparing for Second Spacewalk and Soyuz Departure

Commander Jeff Williams and Flight Engineer Kate Rubins are going back outside the International Space Station Thursday morning for their second spacewalk in less than two weeks. The duo will retract and cover a thermal control radiator no longer being used and install lights and a new high definition camera for better views of Earth …
Installation of Next Level of Work Platforms for NASA’s Space Launch System Begins at Kennedy Space Center

The first half of the E-level work platforms, E South, was installed Aug. 26 in High Bay 3 inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. The platform was lifted up by crane from the floor of the transfer aisle and lowered into the high bay for installation about 246 …
Challenging Back Half
ATom-1, the first of four ATom deployments over the next few years, is about to wind down. We’ve covered over 60,000 km and flown all the way around the world, but unlike the Jules Verne classic, it took us only 24 days (and not 80) to make it back to Palmdale, California. I managed not […]
August Puzzler
Every month on Earth Matters, we offer a puzzling satellite image. The August 2016 puzzler is above. Your challenge is to use the comments section to tell us what part of the world we are looking at, when the image was acquired, what the image shows, and why the scene is interesting. How to answer. Your answer can be […]
6 Ways Earth Observations Tackle Real-World Problems
This summer, recent college graduates and early career professionals launched 30 small research projects as part of NASA’s DEVELOP program. The aim is to use NASA satellite observations of Earth to address an environmental or public policy issue. The young researchers have just 10 weeks to do it! On Aug. 10, 2016, the “DEVELOPers” gathered at NASA Headquarters […]
Mathematicians from the 18th Century
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 […]
