Countdown to Mars: Nasa's Orion capsule that will take man to the red planet passes first parachute tests

  • Orion spacecraft will take its first flight into space in December
  • Unmanned flight will take it 3,600 miles above Earth, in a 4.5 hour mission
  • Craft will eventually be used to take man to Mars

The spacecraft it is hoped will take man to Mars has passed its first parachute tests with flying colours.

Nasa’s Orion spacecraft landed gently using its parachutes after being shoved out of a military jet at 35,000 feet.

It is hoped the craft will take astronauts to an asteroid in 2018, before eventually helping ferry man to Mars.

HOW ORION WILL RETURN TO EARTH

During its return to Earth, Orion will reach a speed of up to 20,000 mph and experience temperatures near 4,000 degrees Fahrenheit.

Once Orion has made it through the atmosphere, the parachute system, with two drogue parachutes and three massive main parachutes that together cover almost an entire football field will be responsible for slowing it down to just 20 mph for a safe splashdown in the Pacific Ocean.

The test version of Orion touched down safely in the Arizona desert after being pulled out of a C-17 aircraft, 35,000 feet above the U.S. Army's Yuma Proving Ground.

It was the first time some parachutes in the system had been tested at such a high altitude.

Engineers also put additional stresses on the parachutes by allowing the test version of Orion to free fall for 10 seconds, which increased the vehicle's speed and aerodynamic pressure.

'We've put the parachutes through their paces in ground and airdrop testing in just about every conceivable way before we begin sending them into space on Exploration Flight Test (EFT)-1 before the year's done,' said Orion Program Manager Mark Geyer.

'The series of tests has proven the system and will help ensure crew and mission safety for our astronauts in the future.' After Orion's free fall, its forward bay cover parachutes deployed, pulling away the spacecraft's forward bay cover, which is critical to the rest of the system performing as needed.

The parachutes that slow Orion to a safe landing speed are located under the cover, so the cover must be jettisoned before they can be unfurled.

Engineers also rigged one of the main parachutes to skip the second phase of a three-phase process of unfurling each parachute, called reefing.

This tested whether one of the main parachutes could go directly from opening a little to being fully open without an intermediary step, proving the system can tolerate potential failures.

The test also marked the last time the entire parachute sequence will be tested before Orion launches into space in December on its first space flight test, EFT-1.

During the flight, an uncrewed Orion will travel 3,600 miles into space, farther than any spacecraft built to carry humans has been in more than 40 years.

ORION'S FIRST FLIGHT

Orion is being prepared for its first launch later this year, an uncrewed flight that will take it 3,600 miles above Earth, in a 4.5 hour mission to test the systems critical for future human missions to deep space.

After two orbits, Orion will reenter Earth’s atmosphere at almost 20,000 miles per hour before its parachute system deploys to slow the spacecraft for a splashdown in the Pacific Ocean.

Orion will travel at the speed necessary to test many of the systems critical to NASA's ability to bring astronauts home safely from missions to deep space, including an asteroid and eventually Mars.

During its return to Earth, Orion will reach a speed of up to 20,000 mph and experience temperatures near 4,000 degrees Fahrenheit.

Once Orion has made it through the atmosphere, the parachute system, with two drogue parachutes and three massive main parachutes that together cover almost an entire football field will be responsible for slowing it down to just 20 mph for a safe splashdown in the Pacific Ocean.

Earlier this months, engineers began stacking the crew module on top of the completed service module, the first step in moving the three primary Orion elements –crew module, service module and launch abort system – into the correct configuration for launch.

'Now that we're getting so close to launch, the spacecraft completion work is visible every day,' said Mark Geyer, NASA's Orion Program manager.

'Orion's flight test will provide us with important data that will help us test out systems and further refine the design so we can safely send humans far into the solar system to uncover new scientific discoveries on future missions.'

With the crew module now in place, the engineers will secure it and make the necessary power connections between to the service module over the course of the week.

Once the bolts and fluid connector between the modules are in place, the stacked spacecraft will undergo electrical, avionic and radio frequency tests. The modules are being put together in the Final Assembly and System Testing (FAST) Cell in the Operations and Checkout Facility at Kennedy.

Here, the integrated modules will be put through their final system tests prior to rolling out of the facility for integration with the United Launch Alliance Delta IV Heavy rocket that will send it on its mission.

Nasa's Orion spacecraft, illustration shown, is due to complete its first unmanned test flight towards the end of this year. The spacecraft will eventually be able to take four astronauts on missions lasting at least 21 days, although this could be extended with a service module currently being researched and developed by Esa

Orion's flight test also will provide important data for the agency’s Space Launch System (SLS) rocket and ocean recovery of Orion.

Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have built an advanced adapter to connect Orion to the Delta IV Heavy rocket that will launch the spacecraft during the December test.

How it compares: The SLS is larger than the Saturn rockets than launched man to the Moon. It will also be more powerful than any rocket in operation today. Russia's super-rocket design has yet to be unveiled. However construction of the first stage of Russia's super-rocket - capable of lifting 80 tonnes - is already underway

Earlier this month Nasa began ramping up excitement for sending humans to Mars, outlining its path to the red planet, and showcasing some of the technologies that will help people get there.

But as revealed in a 286-page National Research Council (NRC) report commissioned by the agency, Nasa has been warned that its efforts will be doomed to fail if it does not change its methods.

The scathing assessment claims that without sufficient funding, a clear goal, or help from nations such as China, Nasa will not be capable of making the next giant leap for mankind.

According to the NRC's report, Pathways to Exploration - Rationales and Approaches for a U.S. Program of Human Space Exploration, the U.S. should abandon its 'flexible approach' to human missions beyond Earth, set Mars as its ultimate goal and open the door to partnerships with other partners including China.

NASA'S THREE PATHS TO MARS ACCORDING TO THE NRC

*Note: all three options assume ISS missions have been concluded
Option 1 - A 'giant leap' from moon to Mars
- Return to the moon

- Build a lunar base

- Send humans to the surface of Mars

Option 2 - Least technological risk
- Send humans into lunar orbit

- Visit an asteroid in its own orbit

- Return to the moon's surface

- Explore Martian moons Deimos and Phobos

- Enter orbit around Mars

- Land on the red planet

Option 3 - Nasa's current favoured path
- Robotically capture an asteroid

- Place it in lunar orbit for astronauts to visit

- Travel to the moons of Mars

- Place humans in Martian orbit

- Set foot on Mars

This flexible approach currently involves the construction of a heavy-lift rocket known as the Space Launch System (SLS) and a manned capsule spacecraft called Orion.

Both of these are seen as necessities for future missions beyond low-Earth orbit - but as of yet neither has a solid goal beyond a few test flights leading up to 2021.

The NRC recommends Nasa chooses one of three stepping-stone approaches toward Mars, that build technological know-how through a series of well-defined preliminary missions.

All three options begin with the International Space Station (ISS).

The station is seen as vital in testing not only technologies for long-term space travel, but also the psychological and biological strains that will be felt by astronauts.

However, the report claims Nasa's current plan of operating the ISS into the next decade, possibly as far as 2028, alongside assembling the technologies to land humans on Mars is not feasible.

Continuing on this path 'is to invite failure, disillusionment, and the loss of the longstanding international perception that human spaceflight is something the United States does best,' said the NRC in its report.

Two of the options then involve sending humans back to the moon, something not favoured by the Obama administration.

'I just have to say pretty bluntly here: We’ve been there before,' Obama said in 2010 when outlining Nasa's space policy for the forthcoming years.

President Obama has repeatedly stated his opposition to returning to the moon (artist's illustration of a cancelled Nasa concept shown), saying we have been there before, and should instead look to do new missions such as sending astronauts to an asteroid and ultimately, of course, exploring the surface of Mars

But these paths would be less technologically daunting, NRC panel co-chairman Jonathan Lunine of Cornell University said.

One suggestion is that Nasa could follow the International Space Station program, which currently costs the United States about £1.8 billion ($3 billion) a year, with a series of lunar sorties - an outpost on the moon and then a mission to Mars, according to the report.

The other moon-based option would follow the space station with human missions to an orbit beyond the moon, then to an asteroid in its native orbit, then to the lunar surface, the moons of Mars, Martian orbit and then to Mars itself.

This would have the most stops en route to Mars, but poses the least technological risk because milestones have to be met along the way, claimed the NRC.

The third path includes Nasa's current plan to robotically capture an asteroid, redirect it into a high orbit around the moon and send astronauts there to explore.

The report suggests that the path should continue with missions to the moons of Mars, then on to Martian orbit, and finally to the surface of the planet.

 

Since the end of the Space Shuttle program, NASA technicians have been developing a new Space Launch System (SLS), along with a new manned spacecraft named Orion, designed to once again lift astronauts beyond low-Earth orbit, and return them safely home. Years of development and testing are leading up to the first planned (unmanned) launch of Orion in December, sending it 3,600 miles into space atop a Delta 4 Heavy booster. The complete system is scheduled for a an unmanned lunar-orbit test in 2017. Long-term, Orion and the SLS will serve as both transport and a home to astronauts during future long-duration missions to an asteroid, Mars and other destinations throughout our solar system.

Wind Tunnel Testing for the new Space Launch System (SLS), September 20, 2013 Environmental factors, like wind gusts, can factor into an aircraft's performance. The SLS, NASA's new heavy-lift launch vehicle, is no exception when it comes to Mother Nature. NASA engineers and contractors recently completed liftoff transition testing of a 67.5-inch model of the SLS in a 14-by-22-foot subsonic wind tunnel at NASA's Langley Research Center in Hampton, Virginia. Instead of learning how environmental factors affect the SLS only during flight, engineers have started at the beginning to improve understanding of how the environment also affects the rocket while it sits on the pad, ready for liftoff.

Engineers install J-2X engine E10002 in the A-1 test stand at NASA's Stennis Space Center, on May 14, 2013. The installation is in preparation for a new series of tests, where the engine will be gimbaled, or pivoted, during test firings. Gimbal tests are an important part of the design process. When this upper stage engine is used in space, it will need to be able to move freely to steer NASA's Space Launch System, or SLS -- an advanced heavy-lift launch vehicle that will provide an entirely new national capability for human exploration beyond Earth's orbit. Once this series of tests is complete, the engine will be removed, and preparations will be made to begin testing the RS-25 engine on the A-1 stand in 2014. RS-25 engines from the Space shuttle inventory will power the core stage of SLS, while the J-2X engine will power the upper stage of the evolved launch vehicle. (NASA/SSC) #
