Some hydrologists thought there might be just enough water; others were less optimistic. It turns out the optimists were right, though just barely. For […]
Advanced Colloids Experiment (ACE)-M-2 Sample Mixing: Commander (CDR) Swanson mixed ACE-M-2 samples in preparation for sample analysis which will take place in the Fluids Integrated Rack (FIR) at a later date. In the ACE-M-2 investigation, a model colloidal system is used to observe the microscopic behavior of liquids and gases separating from each other, near …
Resist Tubule: Yesterday, Commander (CDR) Swanson removed the Resist Tubule samples from the +2 Celsius Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI), inserted the samples into Measurement Experiment Unit B and attached the unit inside the Cell Biology Experiment Facility (CBEF) micro-gravity Incubator Unit (IU). Today, Swanson inserted more samples from the MELFI …
Step outside and take a look at the skies on the evening of May 23 into the early morning of May 24. Scientists are anticipating a new meteor shower, the May Camelopardalids. No one has seen it before, but the shower could put on a show that would rival the prolific Perseid meteor shower in …
Every month we offer a puzzling satellite image here on Earth Matters. The April 2014 puzzler is above. Your challenge is to use the comments section to tell us what the image shows, what part of the world we are looking at, when the image was acquired, and why the scene is interesting. How to answer. Your answer […]
SpaceX-3 Release: Today ISS CDR Swanson completed closeout of the Node 2 nadir vestibule, removed the final power jumpers and closed the Node 2 nadir hatch. He then depressed the vestibule and demated the Common Berthing Mechanism (CMB) bolts and latches. Using the Space Station Robotic Manipulator System (SSRMS) robotics ground controllers performed the SpaceX …
Double Cold Bag (DCB) Packing: ISS CDR Swanson and FE-1 Skvortsov packed six DCBs with conditioned science samples for return on SpaceX-3. SpaceX-3 Departure Preparations: Swanson completed the final SpaceX-3 cargo loading. He then completed the SpaceX-3 egress and vestibule closeout procedures, including installation of the Common Berthing Mechanism (CBM) Controller Panel Assemblies (CPAs). Finally, …
SpaceX-3 Dragon Cargo Packing: ISS CDR Swanson & FE-1 Skvortsov completed several cargo transfer activities today, including the transfer of all powered payloads for return. Dragon is now loaded with two Glaciers, one Commercial Generic Bioprocessing Apparatus (CGBA), and a Biotube Micro (unpowered) in the powered middeck locker locations. Final transfer of the center stack …
Last night at 8:38:30 PM CDT, a basketball size meteoroid entered the atmosphere 63 miles above Columbia, South Carolina. Moving northwest at 78,000 miles per hour, it burned up 52 miles above the Tennessee country side, just north of Chattanooga. This fireball was not part of any meteor shower and belongs to a class of …
