A Virtual Astronaut Tissue Analog Response
A small experiment flying aboard Artemis II that would result in massive impacts in healthcare, each for astronauts in house and residents on Earth.
Biological & Physical Sciences Investigation:
AVATAR (A Virtual Astronaut Tissue Analog Response)
The AVATAR (A Virtual Astronaut Tissue Analog Response) investigation will use organ-on-a-chip units, or organ chips, to check the results of elevated radiation and microgravity on human well being.
NASA’s organ chip analysis will examine how completely different house stressors have an effect on tissue earlier than sending the primary people —Americans — to Mars. It may present helpful info for creating measures to guard astronaut well being on their journeys, akin to customized medical kits.

What Are Organ Chips?
Organ chips are roughly the dimensions of a USB drive and could possibly be used to foretell how a person may reply to a wide range of stressors, akin to radiation or medical therapies, together with prescribed drugs. Made with human cells, the chips mimic how tissues, such because the mind, coronary heart, liver, or dozens of different organs, work. NASA analysis will concentrate on validating and leveraging these fashions to evaluate the impacts of deep house stressors on astronauts’ well being.
Learn More about What Are Organ Chips?
Organ chips may assist guarantee crew well being on long-duration missions by figuring out individualized responses to deep house stressors and personalizing medical kits to future astronauts.
This analysis, mixed with different research on the well being and efficiency of Artemis II astronauts, will give NASA perception into find out how to defend astronauts as exploration expands to the floor of the Moon, Mars, and past.

ORGAN CHIP RESEARCH
Why We Study Bone Marrow
The AVATAR organ chips will comprise bone marrow tissue developed from the cells of Artemis II astronauts. Bone marrow is accountable for producing pink blood cells, white blood cells, and platelets. This makes marrow an excellent pattern for diagnosing illnesses and gauging how an individual’s immune system responds to therapies.
Investigating how radiation impacts the bone marrow can present insights into how radiation remedy and different DNA-damaging brokers, akin to chemotheraputic medicine, impair blood cell formation. Its significance for each spaceflight and medication on Earth makes the bone marrow an excellent organ to check within the Artemis II AVATAR venture.

A Passenger for Research
When the organ chips return from their Artemis flight, researchers will study how spaceflight affected the bone marrow chips by performing single-cell RNA sequencing, a robust approach that measures how 1000’s of genes change inside particular person cells.
For NASA, this analysis may present vital details about how every astronaut responds to the distinctive circumstances of house and inform the event of countermeasures and customized medical kits for future missions. For different authorities businesses and well being organizations, AVATAR may contribute to advances in safer and sooner drug testing, and customized medication on Earth.
