By Eric Lindstrom One of the popular topics of conversation during the first week of the voyage has been sleep. Whether it is poor sleep, good sleep, disturbed sleep, or deep sleep, almost everyone in the science party has had something to say about the subject of sleep. Sleep on a ship is special. As […]
Hi there, Last blog post of for this field season, as Olivia mentioned in her science post, we were able to collect an important amount of high-quality data to further our knowledge of firn aquifers and try to answer the following research questions: How fast is the water flowing in the firn aquifers? How permeable […]
Command and Control (C&C) Multiplexer Demultiplexer (MDM) Transition : The ground executed a planned C&C MDM transition today. C&C 2 MDM was transitioned to primary with C&C 3 MDM in backup and C&C 1 MDM in standby. The transition supports the desired configuration for OA-5, ensuring that the primary Guidance, Navigation and Control (GN&C) MDM …
Three astronauts are relaxing today after a spacewalk on Friday and weekend cleanup work. Meanwhile, a pair of spacecraft will be departing the International Space Station over the next two weeks. NASA astronauts Jeff Williams and Kate Rubins successfully installed a new international docking adapter Friday morning during a five hour and 58-minute spacewalk. Japanese …
By Eric Lindstrom As I mentioned in a previous blog post, the R/V Revelle is bristling with meteorological sensors. Some are permanently installed aboard, some are just for SPURS-2, and some are on the moorings we will deploy. Raymond Graham, a graduate student at University of Connecticut, did a quick count of meteorological sensors and […]
U.S. Extravehicular Activity (EVA) #36: Williams (EV-1) and Rubins (EV-2) completed the following activities to install the International Docking Adapter (IDA)2 with Intravehicular (IV) support from FE-5: Pressurized Mating Adapter (PMA)-2 setup Preliminary IDA installation Initial IDA cable installation PMA-2 hemi reflector cover installation Final IDA cable installation IDA outfitting IDA cleanup IDA3 cable routing …
Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins concluded their spacewalk at 2:02 EDT. During the five-hour and 58-minute spacewalk, the two NASA astronauts successfully installed the first of two international docking adapters (IDAs). The IDAs will be used for the future arrivals of Boeing and SpaceX commercial crew spacecraft in development under NASA’s …
As the DC-8 flies around the world for the ATom project, we are crossing many time zones and occasionally loosing and gaining days! For most of the first half of the project, I didn’t really notice these time changes. I gained the most time leaving Boston for California and had one to two hourly stretches […]
By Eric Lindstrom One of the most common questions I get (and the first comment to this blog) is “How do you measure ocean salinity from space?” During the SPURS-1 campaign in 2012 I wrote a blog post on this topic. Basically the story is one of building a very sensitive instrument (a radiometer) to […]
Two NASA astronauts switched their spacesuits to battery power this morning at 8:04 a.m. EDT aboard the International Space Station to begin a spacewalk planned to last some six and a half hours. Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins will install the first of two international docking adapters (IDAs) that will …
