Rodent Research Mission on ISS National Lab Enables Investigators to Leverage Space-Flown Specimens

KENNEDY SPACE CENTER (FL), July 18, 2019 (ISS National Lab PR) – Onboard SpaceX’s 18th commercial resupply services mission contracted by NASA, the International Space Station (ISS) U.S. National Laboratory will send 40 female mice to the microgravity environment of the orbiting platform to evaluate their adaptation off Earth. Rodent spaceflight experiments provide a broad range of translational data pertinent to biomedical advancements in neurology, muscle and bone physiology, immunology, and cardiovascular and developmental biology.

Due to the tremendous demand from the research community for leveraging model organisms, the ISS National Lab announced its second Rodent Research Reference Mission earlier this year—allowing researchers the ability to analyze rodents post-spaceflight in an effort to accelerate medical breakthroughs that can pave the way toward advancements in industrial biomedicine, improving patient care on Earth.

With this launch, 30 mice will be returned alive to Earth at the completion of the SpaceX Dragon spacecraft’s stay on station (approximately 30 days), while the remaining 10 will remain on the orbiting laboratory for additional exposure to microgravity.

This Rodent Research Reference Mission will allow selected researchers to further analyze biological specimens toward better disease modeling or potentially accelerated development of therapeutics for terrestrial use. Below highlights principal investigators (PIs) selected from the second Rodent Research Reference Mission who will analyze space-flown biospecimens:
