Цитировать Jack Beyer @thejackbeyer 33 мин. назадHey Space Fans, I'll be taking over Dragon tracking for @Julia_Bergeron for CRS-20 as she has her hands full at work and I'll be here in Los Angeles to catch its return.NRC Quest is currently working to get Dragon in the nest at the recovery zone #SpaceXFleet @NASASpaceflight
ЦитироватьISS Daily Summary Report – 4/06/2020The crew will work late into the nominal crew work day today to prepare Dragon for unberth and release tomorrow morning. The next daily report will resume on Wednesday, April 8th.PayloadsOver the weekend:CASIS PCG 10:The crew transferred five sample cards into MELFI to freeze in preparation for a return on SpX-20. Microgravity Crystallization of Glycogen Synthase-Glycogenin (CASIS PCG 10) uses the microgravity environment aboard the International Space Station (ISS) to grow larger, higher resolution versions of two proteins, glycogen synthase 1 and glycogen synthase 2. Understanding the structure of the human glycogen synthase protein will expedite the discovery of treatments for obesity, rare glycogen storage disorders, and potentially cancer.[свернуть]Multi-use Variable-g Platform (MVP2 Cell-03):The crew removed 5 Emory Modules and associated hardware from the MVP2 and prepped the contents for SpX-20 return. This project studied the generation of cardiomyocytes, specialized heart muscle cells, for use in research and clinical applications. Specifically, the team is studying the differentiation of these heart cells from induced pluripotent stem cells (iPSCs), adult cells that have been altered to reinstate characteristics of natural stem cells. Simulated microgravity studies have allowed the team to increase the yield, purity, and survival of cardiomyocytes derived from iPSCs, and true spaceflight conditions are expected to further enhance these effects. Understanding how microgravity improves cardiomyocyte differentiation will enable the team to create clinically relevant heart tissue for use in regenerative medicine, disease modeling, and drug discovery.[свернуть]NanoRacks Module-9:The crew opened the blue clamps and shook tubes 4 and 5 to deactivate them. Tubes 4 and 5 contain experiments which study the effect of microgravity on the growth of Trametes versicolor mycelium, and the effect of microgravity on the growth of Pyropia respectively. Module-09, which contains several mixture tube experiments, was then restowed for return on SpX-20. The experiments use NanoRacks MixStix, miniature laboratories activated by space station crew and eventually returned to the student teams on Earth for analysis.[свернуть]NanoRacks Science Box (aka NanoRacks Black Box):The crew un-cabled and removed the NanoRacks Science Box from EXPRESS Rack and prepped it for SpX-20 return. NanoRacks-Black Box is a key part of NanoRacks' next generation International Space Station platforms. This new platform is specially designed to provide near-launch payload turnover of autonomous payloads while providing advanced science capabilities for customers, including use of robotics, new automated MixStix and NanoLab-style research. Black Box is a locker-sized platform that accommodates up to 18U of payloads.[свернуть]Space Tango MultiLab Locker (TangoLab-2):The crew removed card 012 and Cube BOST_FLW01 from the TangoLab-2 facility and prepared them for SpX-20 return. TangoLab-2 is a reconfigurable general research facilities designed for microgravity research and development and pilot manufacturing in the ISS.[свернуть]Today's activities:Mouse Mission-5 (MM-5):The crew performed the activities necessary to transfer the JAXA MM-5 mice to SpX-20 for return to the ground. The purpose of this mission is to analyze any alterations of the gene expression patterns and the effects on the germ-cell development of mice exposed to a long-term space environment.[свернуть]OsteoOmics-2:The crew removed the samples for their locations in the GLACIER and MELFI freezers/refrigerators and prepared them for return on SpX-20. Millions of Americans experience bone loss, which results from disease or the reduced effects of gravity that can occur in bed-ridden patients. OsteoOmics tests whether magnetic levitation accurately simulates the free-fall conditions of microgravity by comparing genetic expression osteoblastic cells, a type of bone cell, levitated in a high-field superconducting magnet with cells flown in low-Earth orbit. This information helps scientists determine the molecular and metabolic changes that take place in magnetic levitation and real microgravity.[свернуть]Space Cells-01:The crew retrieved Space Cells-01 samples (4) from the CGBA (Commercial Generic Bioprocessing Apparatus) and stowed them for SpX-20 return. Space Cells-01 examines gene expression changes and genetic mutations in hemp and coffee plant cells in microgravity. Cell cultures spend approximately one month on the space station then return to Earth for analysis of their physical structure and gene expression and are compared to preflight parameters. Results could help identify new varieties or chemical expressions in the plants and improve understanding of how plants manage the stress of space travel.[свернуть]SystemsSpX-20 Cargo Operations:Today the crew will complete the final SpaceX-20 mission cargo transfers; including the packing of Double Cold Bags (DCB) that are used to preserve time critical science. Following the final cargo loading, the crew will egress the Dragon vehicle, close the hatch, rotate the Common Berthing Mechanism (CBM) Controller Panel Assemblies (CPAs), and will close out the Node 2 nadir vestibule. Dragon is scheduled to depart the ISS on Tuesday, April 7th at 8:05am CT.[свернуть]

Цитировать Jack Beyer @thejackbeyer 20 мин. назадNRC Quest is currently headed north back towards Los Angeles at ~10 knots after recovering the final Cargo Dragon to return from the ISS. As of now it's looking like it'll arrive sometime tomorrow morning. I can't wait to go see it! #SpaceXFleet @julia_bergeron @NASASpaceflight

Цитировать Jack Beyer @thejackbeyer 24 мин. назадThe final SpaceX Cargo Dragon to be sent to and return from the International Space Station has arrived at the Port of LA aboard recovery vessel NRC Quest. This is the last West Coast recovery operation for the forseeable future. #SpaceXFleet @NASASpaceflight

Цитировать Jack Beyer @thejackbeyer 28 мин. назадYou know how in movies sad stuff always happens on rainy days? Well today was a very cinematic end for Cargo Dragon. It's back on land and safely inside it's lair. Congrats on a job well done to SpaceX and everyone who worked on the Dragon program. #SpaceXFleet @NASASpaceflight15 мин. назадDetails, I wanna see details!
