NASA Armstrong Flight Research Center photographer Lauren Hughes takes photos of the Super Blue Blood Moon eclipse from California’s Trona Pinnacles Desert National Conservation for the Jan. 31 of the total lunar eclipse that provided a rare opportunity to capture a supermoon, a blue moon and a lunar eclipse at the same time. A supermoon occurs when the Moon is closer to Earth in its orbit and appearing 14 percent brighter than usual. As the second full moon of the month, this moon is also commonly known as a blue moon, though it will not be blue in appearance. The super blue moon passed through Earth’s shadow and took on a reddish tint, known as a blood moon. This total lunar eclipse occurs when the Sun, Earth, and a full moon form a near-perfect lineup in space. The Moon passes directly behind the Earth into its umbra (shadow).

Spacelab

While instruments on the pallets in the payload bay observed the universe, biological experiments were performed in the middeck of the Shuttle Orbiter Challenger. Studying life processes in a microgravity environment can shed new light on the functioning of biological systems on Earth. These investigations can also help us understand how living organisms react to prolonged weightlessness. One such experiment was the vitamin D metabolites and bone demineralization experiment. This investigation measured the vitamin D metabolite levels of crew members to gain information on the cause of bone demineralization and mineral imbalance that occur during prolonged spaceflight as well as on Earth. Research into the biochemical nature of vitamin D has shown that the D-metabolites play a major role in regulating the body's calcium and phosphorus levels. One major function of the most biologically active vitamin D metabolite is to regulate the amount of calcium absorbed from the diet and taken out of bones. This investigation had two phases. The first was the developmental phase, which included extensive testing before flight, and the second, or final phase, involved the postflight analysis of the crew's blood samples. This photograph shows astronaut Story Musgrave in the middeck of the Shuttle Orbiter Challenger, attending to the blood samples he collected from crew members for the experiment.

KENNEDY SPACE CENTER, FLA. - An employee gets a blood pressure check from one of the participating organizations in Spaceport Super Safety and Health Day at KSC and Cape Canaveral Air Force Station. Many vendors and Center organizations displayed and demonstrated their products during the annual event dedicated to reinforcing safe and healthful behaviors in the workforce.

Astronaut Charles Conrad as test subject for Lower Body Negative Pressure

S73-27707 (9 June 1973) --- Astronaut Charles Conrad Jr., Skylab 2 commander, serves as test subject for the Lower Body Negative Pressure (MO92) Experiment, as seen in this reproduction taken from a color television transmission made by a TV camera aboard the Skylab 1/2 space station cluster in Earth orbit. Scientist-astronaut Joseph P. Kerwin, Skylab 2 science pilot, assists Conrad into the LBNP device. Kerwin served as monitor for the experiment. The purpose of the MO92 experiment is to provide information concerning the time course of cardiovascular adaptation during flight, and to provide inflight data for predicting the degree of orthostatic intolerance and impairment of physical capacity to be expected upon return to Earth environment. The data collected in support of MO92 blood pressure, heart rate, body temperature, vectorcardiogram, LBNPD pressure, leg volume changes, and body weight. Photo credit: NASA

Coleman during ICV Assessment in the Kibo JPM during Expedition 26

ISS026-E-015923 (7 Jan. 2011) --- NASA astronaut Catherine (Cady) Coleman, Expedition 26 flight engineer, participates in the ambulatory monitoring part of the Integrated Cardiovascular (ICV) assessment research experiment in the Kibo laboratory of the International Space Station. Coleman is wearing electrodes, a Holter Monitor 2 (HM2) for recording Electrocardiogram (ECG), a European Space Agency (ESA) Cardio pressure / Blood Pressure unit to continuously monitor blood pressure and two Actiwatches (hip/waist and ankle) for monitoring activity levels.

STS-58 crewmembers participate in baseline data collection

S93-45375 (29 Sept 1993) --- Astronaut David A. Wolf, STS-58 mission specialist, has blood drawn from his leg for volume measuring. The blood draw was part of the cardiovascular function data collection in preparation for the Spacelab Life Sciences (SLS-2) mission. The seven Spacelab Life Sciences crewmembers devoted a full day to miscellaneous biomedical data collection in preparation for next month's two week mission aboard Columbia.

51F-13-021 (29 July-6 Aug 1985) --- Astronaut Story Musgrave, STS51F mission specialist, is seen hitching a zero-g ride on a blood centrifuge on the middeck of the space shuttle Challenger. "The centrifuge got more workout than just separation of our blood," crewmate John Bartoe, payload specialist, later told a gathering of media representatives at the 51F post-flight press conference, referring to Musgrave's off-duty antics.

Marrow Breath and Ambient Air Sample Collection

iss056e005940 (6/10/2018) --- Air sample collection hardware for The MARROW Study (Bone Marrow Adipose Reaction: Red or White?). The Marrow investigation looks at the effects of microgravity on bone marrow and analyzes breath samples to measure red blood cell function to help doctors understand how blood cell production is altered in microgravity. Results may improve the health of astronauts on long-term missions and help patients on Earth with mobility and age-related issues.

Horse Serum Albumin crystals grown during the USML-1 (STS-50) mission's Protein Crystal Growth Glovebox Experiment. These crystals were grown using a vapor diffusion technique at 22 degrees C. The crystals were allowed to grow for nine days while in orbit. Crystals of 1.0 mm in length were produced. The most abundant blood serum protein, regulates blood pressure and transports ions, metabolites, and therapeutic drugs. Principal Investigator was Edward Meehan.

SpaceX CRS-22 Return

Senior Scientist George Makedonas, from NASA’S Human Immunology and Virology Lab, works with blood samples returned to Earth on SpaceX’s 22nd commercial resupply services mission in the Space Station Processing Facility (SSPF) at Kennedy Space Center in Florida, on July 10, 2021. After its successful parachute-assisted splashdown off the coast of Tallahassee, Florida at 11:29 p.m. EST on July 9, the SpaceX cargo Dragon returned more than 5,300 pounds of scientific experiments and other cargo from the International Space Station. Splashing down off the coast of Florida enables quick transportation of the science aboard the capsule to the SSPF, delivering some science back into the hands of the researchers as soon as four to nine hours after splashdown. This shorter transportation timeframe allows researchers to collect data with minimal loss of microgravity effects.
