Progress 54P Launch and Dock: Today, 54P launched successfully from the Baikonur Cosmodrome at 10:23am CST. After a nominal ascent then performing a four orbit rendezvous, the spacecraft docked automatically to the ISS DC-1 docking port at 4:22pm CST. The Progress is delivering more than 1400 kg of cargo to the ISS. Microbiome Investigation: Flight …
Last week we shared an image of an 800-kilometer long bloom of marine protists off the coast of Brazil. In satellite imagery, the bloom appeared navy to black in color, even though the species—Myrionecta rubra—appears red when viewed close-up. The blooms tend to occur just below the water surface, so much red light that the […]

Spinal Ultrasound Scan Operations: Flight Engineer (FE)-5 Mastracchio, with assistance from FE-6 Wakata and ground experts, performed his Flight Day 90 Spinal Ultrasound session. This investigation aims to characterize microgravity-associated spinal alterations during and after spaceflight using in-flight ultrasound. Results from this research will provide data to enhance crew health for long duration space missions. …
52 Progress (52P) Undocking: Progress M-20M (52P) vehicle undocked from the Russian Segment Docking Compartment 1 (DC1) nadir port today at 10:21 am CST. Progress will remain on orbit for the non-ISS-related “Изгиь” experiment February 6-10, reentry is currently planned for 9:43 am CST Tuesday, February 11th. Sprint Ultrasound Scans: Flight Engineer (FE)-3 Hopkins performed as …
Halos have a long and rich history in religious art, usually symbolizing the presence of someone or something divine. In the physical sciences, the beautiful displays of light are a sign of something more ordinary—the presence of hexagonal, plate-shaped ice crystals that make up cirrus clouds. As gravity pulls the ice crystals downward, their faces […]
Food Warmer Status: Today, Flight Engineer (FE)-3 Hopkins performed an in-flight repair of the secondary ground wire then placed Food Warmer (S/N 1001) into an alternate location (Express Rack 8 Locker 6), where it subsequently experienced an additional over current trip. Ground teams will continue developing troubleshooting plans for S/N 1001. Meanwhile, the Crew has …
ENERGY (Astronaut’s Energy Requirements for Long-Term Space Flight): Flight Engineer (FE)-3 Hopkins continued with his standardized diet protocol for his 10 day session of ESA’s ENERGY experiment. Today he collected water samples from the Potable Water Dispenser in the US Laboratory module, collected a urine sample, and logged all food and drink consumed. A loss …
