NASA: Parachutes Pass Drop Test, Will be Installed In Orion Spacecraft

The parachute system were "deployed as planned after being dropped from an altitude of 6.6 miles [10.6 kilometers) on July 12, at the US Army Proving Ground in Yuma, Arizona", NASA said in a statement.

The parachutes for NASA’s next crew vehicle, the Orion capsule, intended to carry humans to deep space, has successfully passed a drop test, the US space agency said.

Orion’s full parachute system includes 11 parachutes three forward-bay cover parachutes, two drogue parachutes, three pilot parachutes, and three main parachutes.

These are designed to reduce the capsule’s speed during its descent back to Earth, supporting a safe landing in the ocean.

The parachute system were “deployed as planned after being dropped from an altitude of 6.6 miles [10.6 kilometers) on July 12, at the US Army Proving Ground in Yuma, Arizona”, NASA said in a statement.

Data from, the seventh of eight total tests, “will help NASA engineers certify Orion’s parachutes for missions with astronauts” to moon and Mars.

The test evaluated parachute deployment under conditions that exceeded the requirements for a system carrying crew.

Engineers dropped the dart-shaped test article from an altitude that allowed it to generate enough speed to simulate almost twice as much force on the main chutes as would be expected under normal conditions.

Each of Orion’s three main parachutes expands to 116 feet in diameter and contains enough fabric to cover 80 yards of a football field, but is carried aboard Orion in containers the size of a large suitcase.

For storage, the parachutes are compacted with hydraulic presses at forces of up to 80,000 pounds, baked for two days and vacuumed sealed.

Once packed, they have a density of about 40 pounds per cubic foot, which is roughly the same as wood from an oak tree.

Anticipated Problems That May Effect NASA’s Mars Mission

According to results from the first eight analog space crews, presented at the American Association for the Advancement of Science (AAAS) annual meeting in Washington, D.C., the astronauts are able to successfully complete tasks between 20 and 60 per cent of the time.

Researchers are developing a predictive model to help NASA anticipate conflicts and communication breakdowns among crew members and tick off problems that may make or break the Mission to Mars.

NASA has formalised plans to send a manned mission to Mars, a journey that could involve 250 million miles of travel on a small spacecraft.

To understand the psychological demands of this Mars journey, Northwestern University has charted a multi-phase study conducted in two analog environments — HERA in the Johnson Space Center in Houston and the SIRIUS Mission in the NEK analog located in the Institute for Bio-Medical Problems (IBMP) in Russia.

The varsity will study the behaviour of analog astronaut crews on mock missions, complete with isolation, sleep deprivation, specially designed tasks and mission control, which mimics real space travel with delayed communication.

“Astronauts are super humans. They are people who are incredibly physically fit and extremely smart,” said Leslie DeChurch, Professor at Northwestern.

“We’re taking an already state-of-the-art crew selection system and making it even better by finding the values, traits and other characteristics that will allow NASA to compose crews that will get along,” DeChurch added.

HERA’s capsule simulator houses astronauts for up to 45 days — a mock mission control outside the capsule — that augments the realism with sound effects, vibrations and communication delays.

The next phase of the research, which began on February 15, involves using the model to predict breakdowns and problems a new HERA crew will experience and making changes to “who works with whom, on what, and when”.

The experiment on the SIRIUS analog in Moscow, will begin on March 15, where four Russians and two Americans, will undertake a 120-day fictional mission around the moon, including a moon landing operation. (IANS)
