Parachute System In NASA’s Orion Gets Approved

The knowledge gained through the Orion programme has enabled NASA to mature computer modelling of how the system works in various scenarios.

NASA has successfully completed the final test to qualify Orion’s space capsule’s parachute system for flights with astronauts, ahead of its mission to send humans to the Moon and beyond, the US space agency said.

Engineers evaluated the performance of Orion’s parachute system during normal landing sequences as well as several failure scenarios and a variety of potential aerodynamic conditions to ensure astronauts can return safely from deep space missions, over the course of eight tests at the US Army’s Yuma Proving Ground in Arizona.

“We’re working incredibly hard not only to make sure Orion’s ready to take our astronauts farther than we’ve been before, but to make sure they come home safely,” Orion Programme Manager Mark Kirasich, said in a statement.

“The parachute system is complex, and evaluating the parachutes repeatedly through our test series gives us confidence that we’ll be ready for any kind of landing day situation.”

During the final test, which took place on September 12, a mock Orion was pulled out from the cargo bay of a C-17 aircraft flying higher than 6.5 miles.

The protective ring around the top of Orion that covers the parachute system was jettisoned and pulled away by the first set of Orion’s parachutes, then the remaining parachutes were deployed in precise sequence.

The Orion system has 11 parachutes, a series of cannon-like mortars, pyrotechnic bolt cutters, and more than 30 miles of Kevlar lines attaching the top of the spacecraft to the 36,000 square feet of parachute canopy material.

In about 10 minutes of descent through Earth’s atmosphere, everything must deploy in precise sequence to slow Orion and its crew from about 300 mph to a relatively gentle 20 mph for splashdown in the Pacific Ocean.

The parachute system is the only system that must assemble itself in mid-air and must be able to keep the crew safe in several failure scenarios, such as mortar failures that prevent a single parachute type to deploy, or conditions that cause some of the parachute textile components to fail.

Orion will first fly with astronauts aboard during Exploration Mission-2, a mission that will venture near the Moon and farther from Earth than ever before, launching atop NASA’s Space Launch System rocket — which will be the world’s most powerful rocket. The parachutes for Orion’s upcoming uncrewed flight test — Exploration Mission-1 — are already installed on the vehicle at Kennedy Space Centre in Florida.

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)
