ISS Science for Everyone

Science Objectives for Everyone
Brine shrimp (Artemia), also known as “sea monkeys,” are a hardy genus of small crustaceans that can hibernate when there is no water. They can also produce dormant eggs, which can be stored for long periods and then hatched to provide a source of food for fish. NanoRacks-Darca Bat Yam High School-Emergence of Artemia Eggs (NanoRacks-DBYHS-Artemia) studies whether these dormant eggs will hatch and absorb oxygen in space.

Experiment Description

Research Overview

  • The Artemia crab are part of the human food chain, their birth from very rigorous eggs can be essential for space flight.
  • The need of oxygen is a challenge for the eggs and NanoRacks-Darca Bat Yam High School-Emergence of Artemia Eggs (NanoRacks-DBYHS-Artemia) determines the capability of the eggs to absorb oxygen in space.
  • If the experiment works, Artemias can be used for future food development and coral nutrition.

Description

Artemia, also known as brine shrimp, withstand harsh conditions of high temperatures and pressure. They are found in swamps and during the dry summer go into hibernation waiting for water. When mixed with salt water they hatch and live according to the conditions of their surroundings. NanoRacks-Darca Bat Yam High School-Emergence of Artemia Eggs (NanoRacks-DBYHS-Artemia) determines if Artemia eggs hatch in space. The investigation examines if the eggs have the capability to absorb oxygen in space. If the experiment works, Artemia can be used for future food development in space.

The space community is starting to design and think about long-duration manned space travel. The technologies for these missions are not yet mature enough and food preservation is one of them. Looking for foods and animal nutrition that can withstand long durations or be stowed as eggs for a long time to be aggregated later is an essential feature for space travel.
 
NanoRacks-DBYHS-Artemia is a Ramon Foundations project inspired by Ilan Ramon.

Applications

Space Applications
If humans ever aim to colonize the moon or other planets, they will need a stable source of food. Brine shrimp, which can be hatched after a long period of dehydration, could provide a food source. Brine shrimp eggs are commonly stored on Earth and later rehydrated to serve as an on-demand food supply for fish farms. Proving the eggs can also hatch in the harsh microgravity environment of space could lead to development of a food supply for long-duration space missions.

Earth Applications
Brine shrimp are hardy animals, surviving in very salty water and hibernating when there is no water at all. With greater insight about their endurance, they could be used to provide nutrition in harsh environments on Earth. In addition, the investigation was designed by 14-year-old high school students, who developed the concept as part of a competition. The students gained real-world experience to prepare them for careers in science, technology, engineering and mathematics.

Operations

Operational Requirements and Protocols
The MixStix are unclamped to combine different compartments, typically causing either activation or deactivation of the experiment. The MixStix are returned to the students.
A crew member removes the Velcro tabs to open the Module-9 Ext lid. The crew member unclamps the fasteners on the MixStix as directed, enabling the materials in the various chambers to flow. The crew member then shakes the MixStix (when directed) to mix the liquids thoroughly. Repeat for all MixStix. Crew member notes the time of MixStix activation and replaces the tubes back in Module-9. The lid is replaced and secured with the Velcro tabs.
