Title: Take Me Home
Crew 274 woke up this morning at 7:30am to the theme from Apollo 13. The crew got their surveys done, then prepared for their last EVA of the mission.
EVA Activity
Today, HSO Pender retrieved his supply cache from the field and brough EEVAC-1 back home. He conducted performance metrics and final condition observations of the cache and overall, EEVAC-1 was found in good condition. The solar panels held up surprisingly well given the high winds from the previous evening. Finally, Pender and his EVA team collected the final data set on the orange radiation experiment led by Commander Sarah Guthrie.
GreenHab
Today, GHO Hines officially concluded both the primary and secondary growth experiments. While the secondary microgreen study proved to be a partial success, with the cress seed set resulting in a nearly 80% germination rate, only one seed among the several planted LDEF seeds were able to successfully germinate halfway through the mission. The resulting conclusion is being considered a success based on conservative expectations with plans to continue the study on future analogs.
Hab Design
Hab Specialist Bill O'Hara completed his study of MDRS architecture on schedule today. The result is a comprehensive set of notes regarding the awesome and inspiring design of the MDRS. He also supported the final EVA of the mission to bring home EEVAC-1.
Heliophysics
Crew astronomers Loy and Pena observed detailed heliophysics phenomena and collected more bulk data sets on solar dark spots and solar chromosphere prominences. Large prominences were observed wrapping around solar magnetic fields, just before solar flares were registered by NOAA blasting away from a solar vortex. Eight large solar prominences and nine solar dark spots were observed today, which will be very useful for the astronomer's analysis of solar cycle 25. On top of these observations, 60,000 images were captured, and 10,000 solar spots and prominences were stacked, measured, and analyzed.
Astronomy
59 separate 45-second long exposure images were collected from the MLCRCOS-16 New Mexico Observatory. These images are being separately captured through visual, infrared, and blue filters, assisting Astronomers Pena and Loy's science on HADS variable star research. 59 B filter images were stacked, analyzed, and compared to previous images of this star system, HADS Variable Star V0799 AUR, to provide an assessment of this variable star's brightness variability period and cycle, as well as provide a true-brightness standard to accurately measure distances in the immediate vicinity of HADS V0799 AUR's stellar neighborhood.
