Metagenome profiling of feces from mice flown on the RRRM-1 mission
In Rodent Research Reference Mission-1 (RRRM-1), forty female BALB/cAnNTac mice were flown on the International Space Station. To assess differences in outcomes due to age, twenty 10-12 week-old and twenty 32 week-old mice were flown, respectively. To directly assess spaceflight effects, half of the young and old mice (10 old, 10 young) were sacrificed on-orbit after 22-23 days (ISS Terminal, ISS-T), while the other half (10 old, 10 young) were returned live to Earth after 40 days and allowed to recover for 2 days (Live Animal Return, LAR) before sacrifice. Both the ISS-T and LAR animals had independent ground controls (10 mice housed in flight hardware in matched environmental conditions), basal controls (10 mice sacrificed 1 day after launch), and vivarium controls (10 mice housed within standard vivarium habitats). Thus RRRM-1 included a total of 160 mice. Feces were removed from 145 animals and preserved by flash freezing in liquid nitrogen and stored at -80 ˚C until DNA was extracted, and libraries generated and sequenced (target 10 M clusters per sample, PE 251 bp). This dataset features whole-genome shotgun metagenomics sequencing data from 8-10 feces samples per group.
Metagenome profiling of feces from mice flown on the RR-23 mission
The objective of the RR-23 mission was to better understand the effects of spaceflight on the eyes, specifically on the structure and function of the arteries, veins, and lymphatic vessels that are needed to maintain vision. To this end, twenty male, C57BL/6J, 16-17 weeks-old mice were delivered to the ISS on SpaceX-21 in a single transporter, transferred to two rodent habitats, and maintained in microgravity for 38 days. Flight mice were then returned to Earth alive (Jan 13th, 2021). After splashdown in the Atlantic Ocean, mice were transported to Kennedy Space Center via helicopter. The 20 Flight, 20 Habitat Ground Control (HGC), and 20 Vivarium Ground Control (VGC) mice were removed from Rodent Transporters (Flight and HGC) or vivarium cages (VGC), placed into shipping containers, and flown to Texas A and M University. There, mice underwent post-flight procedures, before euthanasia and tissue collection. Flight, HGC and VGC animals were euthanized and dissected on Jan 14th, 17th or 20th of 2021, respectively. Feces were removed from the animals and preserved by flash freezing in liquid nitrogen and stored at -80 ˚C until DNA was extracted, and libraries generated and sequenced (target 10 M clusters per sample, PE 250 bp). This dataset features 9 samples from the Flight group, 9 samples from the HGC group, and 9 samples from the VGC group.
Whole metagenome profiles of particulates collected from the International Space Station.
The microbial composition of the International Space Station (ISS) environment is of critical interest due to potential impact of its constituents on human health and operational mission success. This study examined the whole metagenome of ISS microbes at both a species- and gene-level resolution. Air filter and dust samples from the ISS were analyzed and compared to samples collected in a terrestrial cleanroom environment. Samples were collected from ISS and cleanroom environments and treated to examine DNA from total versus viable populations. Microbial genes relevant to human health such as antimicrobial resistance and virulence genes were quantified.
SpaceX Inspiration4 Stool Metagenome Profiling
The SpaceX Inspiration4 mission was a 3-day mission with four private astronauts to low Earth orbit that occurred in September 2021. The crew collected biospecimen samples before, during, and after flight. One of these biospecimen collections included stool collected in OMNIgene•GUT tubes (DNA Genotek, OMR-200). Samples were collected pre-flight (L-92, L-44) and post-flight (R+45, R+82). This study hosts stool data. Additional skin, oral and nasal metagenome data is deposited in OSD-572. Dragon capsule data metagenome is deposited in OSD-573. Skin biopsy-site metagenome data is deposited in OSD-574.
