ISS Science for Everyone

Science Objectives for Everyone
The Space Shields: The Inhibition of Gamma Rays via Passive Shielding (Space Tango Payload Card Radiation) investigation uses a Geiger counter to measure radiation levels within four passive casings, or shielding materials, aboard the International Space Station (ISS). Researchers will evaluate each material based on density, cost, and toxicity to determine the most effective material at shielding radiation relative to density. Improved radiation shielding materials for spacecraft could improve the safety of conditions during long term space travel. The Higher Orbits Foundation and the 2016 Andromeda Award Winning Team DASA from Deerfield High School in Deerfield, IL lead this investigation.

Experiment Description

Research Overview

  • The goal of Space Shields: The Inhibition of Gamma Rays via Passive Shielding (Space Tango Payload Card Radiation) is to help improve the safety conditions for long term space travel, and revolutionize radiation safety.
  • Cosmic radiation poses a serious problem to the health of astronauts travelling in space. With long term space travel in sight, astronauts face over 1.1 sieverts of exposure in an 860-day mission to Mars. Exposure to 1 sievert of radiation can increase the risk of cancer by over 5.5%. Leukemia poses a great risk both from radiation and decreased bone density.
  • The microgravity environment in low earth orbit (LEO) is a sample of the radiation that is seen in deep space travel conditions. Although a majority of the radiation present in LEO is reduced by the ISS and TangoLab framework, increased space radiation is expected. Longer experimental duration is desired for maximum radiation exposure.

Description
The Space Shields: The Inhibition of Gamma Rays via Passive Shielding (Space Tango Payload Card Radiation) investigation includes four different passive casing materials that surround a Geiger counter. The Geiger counter measures the radiation levels within each casing over the duration of the mission.

Applications

Space Applications
Improved radiation shielding materials for spacecraft improve the safety of conditions during long term space travel.

Earth Applications
This project advances the overall understanding of radiation safety, which has application in settings on Earth where radiation exposure is a potential risk.

Operations

Operational Requirements and Protocols
The science is contained inside of a one-unit (1U) CubeLab attached to Payload Card-2 for ascent. The Space Tango Payload Card Radiation experiment operates in the TangoLab where the crew installs the payload card and autonomous operations occur. The Payload Card with the Radiation Experiment remains in TangoLab upon the conclusion of SpaceX CRS-12. Upon the arrival of OA-8, the TangoLab (and enclosed experiments) are moved to and installed in the Cygnus vehicle. Following an expected 2-3 weeks of evaluation, the TangoLab is re-installed in its original rack position. The Radiation experiment remains inside the TangoLab until return on SpaceX CRS-13. At that time, the crew removes, conditions, and stows the hardware for return to Earth. The Payload Card is returned and turned over to the Space Tango/PI team during early return either in Houston, Texas or at the California airport.
