Tumbling along like a tumbling tumbleweed Ok, so the title might just have outed my love for all things Lebowski, but hopefully I will be able to make a link, irregardless of how tenuous it might be, between tumbleweeds and and the subject of this post, drifters.

NAAMES-III Expedition: September 18, 2017
Cloud formation depends on several factors, and one of those is the presence of aerosols. Marine aerosols come from a number of sources (sea salt, biogenic aerosols, continental aerosols that are carried over by wind) and differ in size and composition. We’ve collected CCN and CPC data to determine, respectively, the concentration of particles that […]
NAAMES-III Expedition: September 15, 2017
All Quiet in the Main Lab Oceanography is a bunch of tired people filtering the ocean. It reminds me of a Norse story I read a long time ago: Thor was mad at someone so he went to their place to confront them. They were scared of him and his advanced musculature, so they decided […]

Marrow: Today a 52S crewmember conducted breath and ambient air sample collections for the Marrow investigation, which looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone …

Sarcolab-3: After successfully completing three days of the ankle configuration exercises, today USOS and Russian subjects conducted the knee protocol for Sarcolab-3. The subjects ingressed the Muscle Atrophy Research & Exercise System (MARES) chair, installed the knee Electromyography (EMG) electrodes and began the knee exercise protocol, while an operator collected ultrasound images of the subject’s …
Spacewalk VR Training, Muscle and Bone Research Today

The Expedition 53 crew is getting ready for a trio of spacewalks next month while helping scientists understand what living in space does to the human body. NASA astronauts Randy Bresnik and Mark Vande Hei trained for a spacewalk emergency today wearing virtual reality gear. The spacewalkers practiced maneuvering specialized jet packs attached to their …

Searching for the Bluest
It doesn’t take a lot of technology to see that the ocean is blue. And when it comes to the blueness of the ocean, it doesn’t get much more blue than where I am. I’m sitting on the research vessel Nathaniel B. Palmer—the largest icebreaker that supports the United States Antarctic Program—on an oceanographic expedition […]

Space Headaches: The daily questionnaire for the ESA Space Headaches investigation was completed by a 52S crewmember. The Space Headaches investigation collects information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crewmembers in space. Headaches during space flight can negatively affect mental and …
