NASA Langley Research: Hydro Impact Basin

What goes up must come down, and it will be NASA Langley Research Centre's job to make sure that when astronauts return from space, they land safely.

On June 8, NASA Langley will break ground on a $1.7 million Hydro Impact Basin that will serve to validate and certify that future space vehicles, such as NASA's Orion crew module, are designed for safe water landings.

The water basin will be 115 feet (35 m) long, 90 feet (27.4 m) wide and 20 feet (6.1 m) deep and will be built at the west end of Langley's historic Landing and Impact Research Facility, also known as the Gantry, where Neil Armstrong trained for walking on the moon. Construction will begin mid-June and will be completed by December 2010.

A series of water impact tests will be conducted using Orion drop test articles beginning in the spring of 2011. These tests will initially validate and improve the computer models of impact and acoustic loads used in the design and engineering process, and will ultimately qualify the final vehicle design for flight.

"We are excited about being a part of the nation's next space vehicle and it's landing system," said Lynn Bowman, who is managing the series of tests for the Orion project. "Our team has been involved with furthering the knowledge and testing of space vehicle landing systems and their components for the past few years."

The skill sets that NASA Langley engineers and technicians bring to the table as well as the capability of the gantry are two of the reasons the basin is being built at the center.

Bowman explains: "The Gantry provides the ability to control the orientation of the test article while imparting a vertical and horizontal impact velocity, which is required for human rating vehicles."

"This existing capability when combined with the water basin will provide a complete facility needed for landing certification of any manned spacecraft for water landing," added Bowman. "Even vehicles that do not perform a nominal water landing will need to certify for launch abort landings into water."
