Sand and Water

Wonder at Waters

NASA Test Operations Group employees, from left, Todd Pearson, Tim Delcuze and Rodney Wilkinson maintain a water pump in Stennis Space Center's high-pressure water facility. The three were part of a group of employees who rode out Hurricane Katrina at the facility and helped protect NASA's rocket engine test complex.

View of water bubble formed in front of the Japanese Experiment Module (JEM) window. The JEM Exposed Facility (JEF) is visible in the background through the window and reflected in the water. Scratches visible on the window.

This poster highlights NASA JPL missions that provide important inputs to research on global and regional water resources. Water is crucial to life.

This map shows the distribution of water in the stratosphere of Jupiter as measured with the Herschel space observatory. White and cyan indicate highest concentration of water, and blue indicates lesser amounts.

STS034-10-014 (18-23 Oct. 1989) --- An onboard 35mm camera provides a closeup view of an STS-34 beverage container doubling as an experiment module for a test involving iodine concentration in onboard water. The examination called for the adding of starch to a specimen of Atlantis' fuel-cell produced water. The liquid was then compared against the color chart for determining the degree of iodine content. The experiment was designed by Terry H. Slezak of JSC's Photographic Technology and Television Division.

A water tank is lifted into place at the A-3 Test Stand being built at NASA's John C. Stennis Space Center. Fourteen water, liquid oxygen (LOX) and isopropyl alcohol (IPA) tanks are being installed to support the chemical steam generators to be used on the A-3 Test Stand. The IPA and LOX tanks will provide fuel for the generators. The water will allow the generators to produce steam that will be used to reduce pressure inside the stand's test cell diffuser, enabling operators to simulate altitudes up to 100,000 feet. In that way, operators can perform the tests needed on rocket engines being built to carry humans back to the moon and possibly beyond. The A-3 Test Stand is set for completion and activation in 2011.
