Would you like to take a spin?
If you went to space and thought it would be nice to have a feeling of "DOWN", would you, could you, survive in a drum that was spinning in space?
How about taking your exercise inside the Discovery One Centrifuge?

How tight a turn would your eyes and ears and stomach put up with to get the feel of 1G? [The shorter the radius, the faster the spin needed to get 1G and the more you torque your inner ear.]

One of the considerations in choosing an artificial gravity design is the tradeoff between radius and rotation rate to achieve a given g-level at the rim. Human factors issues largely determine the rim velocity and g-level, whereas physiological requirements influence the choice of radius (for g-gradient), glevel and exposure time. Vestibular considerations come into play in two ways. First of all, an adequate artificial gravity stimulus, combined with active head movements and locomotion, would presumably avoid some of the problems leading to re-entry and post landing disorientation and postural instability, although it is possible that astronauts might not be able to adopt a successful "dual state" adaptation. Secondly, the vestibular disturbances associated with cross-coupled angular acceleration when making out-of plane head movements, or Coriolis accelerations when making radial or tangential head movements, can create intra-sensory conflicts leading to motions sickness. These accelerations are directly proportional to the artificial gravity rotation rate. It has been widely assumed that a rotation rate of 1-2 rpm is easily tolerated, and that adaptation by steps can bring tolerance up to 6 rpm.

What can you do here on Earth to simulate being in space? How about spending time in bed with your head lower than your feet for 21 days at a time? Feel the blood rushing to your brain? Your heart doesn't need to work as much to get the blood up there so slack off.
A long time ago we talked about the work done at Ames Research Center to test Astronauts and Johnson Space Flight Center does that too.

I received an e-mail from Maneesh Arya at JSC and it seems they are still looking for a few good men to spend 41 days in a test program.

Dear Mr. Kellogg,
Gunjan Gupta referred me to you. NASA is currently sponsoring an Artificial Gravity project that will be a wonderful opportunity for healthy, adult males on your mailing list for space exploration. Please distribute the attached flyer to anyone who might be interested. The study pays approximately $6,000. Thank you.

Human Test Subject Facility (HTSF)
The Human Test Subject Facility (HTSF) at the Johnson Space Center is responsible for providing qualified test participants for ground-based research. Currently, researchers are working to reduce the effects of space flight on the human body. To accomplish this, researchers study people on Earth, in a way that causes some of the changes the body goes through while traveling in space without gravity. Healthy test subjects are needed from the general population.
The Bed Rest Project Study Team at the Johnson Space Center is planning a series of studies that support the scientific needs of the space program and will be conducted over the next ten years. These studies will develop ways to keep astronauts healthier and safer when they spend a long time in space without gravity. NASA calls these methods countermeasures and uses them to minimize the changes that occur to the body during space flight and enable the return of normal body functions once back on earth.
Currently the HTSF is recruiting participants for the following studies:
+ Bed Rest Study
+ Artificial Gravity Study
+ NASA Seeks Volunteers for Spaceflight Simulation Studies Artificial
+ Gravity for Long Space Missions One Man's Rest is Another Man's
+ Research

Bed Rest Study
In order to study a person as if they were in space without gravity, NASA scientists use head down tilt bed rest. The 115-119 day study will follow the Bed Rest Project standard model and be conducted at the University of Texas Medical Branch in Galveston, Texas. Participants will live in a special research unit for the entire study and be fed a carefully controlled diet.

Artificial Gravity / Bed Rest Project - 41 Days
The purpose of this study is to begin to test how a force created by spinning the space craft could be used to replace gravity during long space flights. This so-called "artificial gravity" is the same force that causes you to lean to the side when you go around a corner quickly in a car. For this study, the artificial gravity will be created by spinning research subjects on a human centrifuge.

Research Participant must be a US citizen or permanent resident to meet the NASA/Johnson Space Center Security requirements to be considered as a potential test subject. You must also meet the Modified Air Force Class III Medical Standard. NASA has determined that all persons who are selected and/or assigned to participate in human subject testing should have initial blood tests as part of the recruitment procedure and physical exam. By providing answers to these medical questions, you begin the screening and eligibility process. We are looking for a population that resembles the NASA astronaut population. If you have any questions regarding the application process, you may leave your contact information by calling 1-866-JSC-TEST.
