Massive 115-foot Rosalind Franklin parachutes successfully tested ahead of Red Planet launch

The British-built Rosalind Franklin rover is one step closer to landing on the surface of the Red Planet after parachute tests in the Oregon desert proved successful.

A pair of parachutes – each 115 feet in diameter – will be used to slow the UK’s very first Martian rover as it lands on the Red Planet in 2023.

It was a large-scale high-altitude drop test of the parachutes, falling 18 miles over the Oregon Desert and “ performed as expected, ” according to the team.

The rover was slated to launch earlier this year – alongside missions from the United States, China and the United Arab Emirates – but delays in testing due to coronavirus restrictions have led the European Space Agency to postpone the start.

There are still other tests to be completed before the new launch date in September 2022 which would see the rover arrive on Mars in early 2023, but this is a ‘major milestone’.

Testing parachutes on Earth requires dropping it from a very high altitude to reproduce as closely as possible the conditions it will experience on the red planet.

Rosalind Franklin is one of three Martian rovers either en route to the Red Planet or set to launch within the next two years – the others are NASA’s Perseverance and China’s Tianwen-1 – both launched this summer and are expected to arrive in February 2021.

Once the Rosalind Franklin reaches Mars in 2023, a six-minute streak will see a descent module deploy two parachutes to slow it down quickly before it lands.

Atmospheric drag will slow the module down from about 13,048 mph to 1056 mph – at which point the first parachute will be deployed – then 20 seconds later at 248 mph the second parachute will open.

When the module is just over half a mile above the ground, the brake motors kick in and deliver it safely to the surface of the planet.

A replica of a `` lander '' was dropped 18 miles over the Oregon Desert as part of the test to see if the parachutes would deploy in the correct order.

The complete parachute descent system needs to be tested and verified on Earth to make sure all is going well – but can only be done via high altitude drop tests to replicate the low atmospheric pressure conditions of Mars.

On November 9, a team of scientists tested the system over Oregon by sending a vehicle 18 miles using a stratospheric balloon – then dropping it.

The tests went as mission scientists had planned, with the test vehicle landing safely and the parachutes recovered.

There was minor canopy damage on both parachutes, which occurred at the onset of inflation, but that wouldn’t be a problem for the actual mission.

Rosalind Franklin – a joint Europe and Russia mission – is expected to launch in 2022, and the mission will attempt to detect life, past or present, on Mars.

The completion of the parachute test marks a critical milestone for the rover, which was built at Stevenage by Airbus, and the team will now analyze the test data to determine further improvements for future tests.

ExoMars program team leader François Spoto said: “Landing on Mars is extremely difficult, with no possibility of error,” adding that it was a good step forward.

The parachute is 115 feet wide, made of a fully expanded nylon fabric that will extend almost 300 feet between the top of the parachute and the lander – the fall will be “ pulled out of its bag ” at over 100 miles per hour.

This is why getting it right on Earth is so important – it’s not something that can be “ fixed ” if it goes wrong 90 million miles away on Mars.

Spoto said that while the latest tests were successful, it still wasn’t the “ perfect result ” they were hoping to achieve – so he will continue to tweak and test.

“ Therefore, we will use the wealth of test data we have acquired to refine our approach, plan for further testing, and stay on track for our launch in September 2022. ”

ALIEN HUNTING CAMERA: ROSALIND FRANKLIN ROVER WILL SEARCH FOR LIFE SIGNS ON MARS

The camera system, called Pan-Cam, was designed by engineers at University College London.

It’s perched atop the rover’s high mast and is equipped with sensors that scan the planet’s surface for minerals or water.

Once it has identified an area, it will move towards it at 47 inches per hour, then dig to biopsy the land.

The samples will then be stored in a stand-alone lab on the rover, where they will be crushed and examined.

The UK company Vorticity Ltd is a technical consultant for the parachute system and is responsible for the high altitude drop tests of the parachutes.

It designed and manufactured the parachute test vehicles, and then performed the test with its US subcontractor, Near Space Corporation.

John Underwood, Principal Engineer at Vorticity, said: “This is an extremely difficult program involving the development of the largest parachute ever to be sent to Mars.

“Huge improvements have been made to the system since last year’s testing, and we are confident that the remaining issues will be resolved before the mission begins.

Sue Horne, head of space exploration at the UK Space Agency, said Mars has been an object of our fascination and speculation throughout recorded history.

She added that “missions to the red planet are not easy”.

“A total of 20 probes, from countries and agencies around the world, have all had their share of crashes on their way to the Red Planet.

“ They crashed on take-off, crashed on landing, lost power.

“Parachute testing is vital to helping us get exactly the right technology and ensuring the Rosalind Franklin rover travels with the best, most reliable equipment possible.

Britain’s last major Martian lander, Beagle 2, landed safely on the Red Planet, but its solar panels were unable to deploy, blocking its ability to communicate with Earth.

EUROPE AND RUSSIA WORK TOGETHER ON THE EXOMARS MISSION TO SEARCH FOR SIGNS OF MARTIAN LIFE

The main goal of ExoMars is to find out if life ever existed on Mars – it will do so through a series of instruments on the surface and in orbit.

This includes an orbiting spacecraft called the Trace Gas ORbiter (TGO) that carries a probe to study traces of gases such as methane around the planet.

Scientists believe that methane, a chemical that on Earth is strongly linked to life, could help identify areas where life exists or could have existed.

The second part of the ExoMars mission, postponed to 2022/2023 due to a coronavirus, will deliver a rover to the surface of Mars.

The rover is under construction in Stevenage, UK, and is named after British scientist Rosalind Franklin.

It will be the first to be able to both move on the surface of the planet and pierce the ground to collect and analyze samples.

The rover will include a technology called Mars Organic Molecule Analyzer (MOMA) that will allow it to analyze samples and send data back to Earth.
