Motors on Mars: The technology being sent to explore Mars

The US space agency, NASA, has announced that its Jet Propulsion Laboratory (JPL) will be sending a helicopter to the Red Planet on the upcoming Mars 2020 rover mission. It will land on Mars while attached to the bottom of the rover in February 2021. During the first 30 days of the mission, it will undertake several autonomous flights, each lasting up to 90 seconds to send the first aerial images (not taken by a satellite) of Mars back to Earth.

For the small helicopter to fly, it takes an enormous engineering effort. The thin air on Mars is comparable to conditions on Earth at an altitude of 30km. Also, taking the reduced Martian gravity into account, the helicopter needs to be very light (1.8kg) and can only carry small batteries.

The components used therefore must be extremely energy-efficient. Six of maxon motors’ 10mm diameter DCX precision micro motors, which have been used in previous Mars missions, will be used to move the swashplate, adjusting the inclination of the rotor blades, to control the vehicle.

The propulsion system is designed and built by AeroVironment, working closely with maxon engineers, under contract from JPL.

“Being part of another Mars pioneering project makes us incredibly proud,” says Eugen Elmiger, CEO of maxon motor.

AeroVironment draws on high-altitude drone development to help make a helicopter for Mars

A Southern California company that specializes in small drones for the military has an opportunity to contribute to aviation history: the first aerial flight on Mars.

AeroVironment Inc. is making the rotors, landing gear and material to hold solar panels for the Mars Helicopter project, which will be assembled at NASA’s Jet Propulsion Laboratory in La Cañada Flintridge. The device will deploy from NASA’s latest Mars rover in 2020, taking high-resolution images that can determine where the slower-wheeled vehicle should head next.

The drone helicopter will look somewhat similar to a hobbyist device you might see whiz by on the beach. But it will incorporate years of research into the challenges of flying in a thin atmosphere that has similar density to about 100,000 feet above Earth’s sea level.

“There’s been a lot of doubts about being able to even fly in the atmosphere of Mars,” said Wahid Nawabi, chief executive of the Monrovia-based company. “It’s been over 100 years since the Kitty Hawk moment. This is the next event.”

Flying in Martian Skies: NASA’s 2020 Rover Mission Will Include Tiny Helicopter

Excitement has been building for NASA’s next rover mission to Mars, scheduled to launch sometime in 2020. Although it looks a lot like the current Curiosity rover, its mission will be to search directly for possible evidence of past life. Curiosity, on the other hand, is studying the ancient habitability of Gale crater, which we now know used to hold a lake or series of lakes, focusing more on geology than biology. And now the upcoming 2020 mission just got even better – NASA has approved the inclusion of a tiny drone-like helicopter to accompany the rover!

This is something never done before, and assuming it’s successful, will be the first time that Mars has been robotically explored by something other than an orbiter, lander or rover.

The Mars Helicopter will be a small, drone-like autonomous rotorcraft, designed specifically for Mars’ very thin atmosphere; it will provide a unique and exciting new way to see the Martian landscape as never before – a bird’s-eye view, if you will. And of course, it’s just very cool.

Potential Mars Airplane Resumes Flight

Flight tests have resumed on subscale aircraft that could one day observe the Martian atmosphere and a variant that will improve collection of Earth’s weather data.

Work on the shape of the aircraft and the systems it will need to fly autonomously and collect data are ongoing for the Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M aircraft. Student interns with support from staff members at NASA Armstrong Flight Research Center in California are advancing the project.

The March flights included two slightly different Prandtl-M aerodynamic models that were air launched from a remotely piloted Carbon Cub. The research validated the airframe that will be the basis for a potential Mars aircraft and the Weather Hazard Alert and Awareness Technology Radiation Radiosonde (WHAATRR) Glider on Earth.

This could be the first airplane on Mars cnet

When I think of airplanes on Mars, I imagine a sci-fi scenario with robotic winged flying machines swarming through the Martian air, gathering data like a flock of hyper-intelligent space seagulls.

The first airplane on Mars will be pretty far from this fantasy. Chances are, it will look a lot more like a kind of glider that’s already in use on Earth, according to a NASA photo released Monday.

The proposed Prandtl-m aircraft is a relatively dainty flying-wing-style plane. The prototype will be based on the existing Prandtl-d, a radio-controlled glider designed and built by aerospace engineering students during a NASA internship in 2012 and 2013.

Helicopter Could be ‘Scout’ for Mars Rovers NASA

Getting around on Mars is tricky business. Each NASA rover has delivered a wealth of information about the history and composition of the Red Planet, but a rover’s vision is limited by the view of onboard cameras, and images from spacecraft orbiting Mars are the only other clues to where to drive it. To have a better sense of where to go and what’s worth studying on Mars, it could be useful to have a low-flying scout.
Enter the Mars Helicopter, a proposed add-on to Mars rovers of the future that could potentially triple the distance these vehicles currently drive in a Martian day, and deliver a new level of visual information for choosing which sites to explore.
The helicopter would fly ahead of the rover almost every day, checking out various possible points of interest and helping engineers back on Earth plan the best driving route.

Robot Airplanes Could Unlock Mars Mysteries Space.com

Various orbiters, landers and rovers that have explored Mars in the past three decades have revealed tantalizing evidence of the conditions for life, from frozen water at the planet’s North Pole to methane plumes in the atmosphere. For atmospheric scientist Joel Levine, the evidence has made the case for flying an airplane over Mars stronger than ever.
Levine champions the ARES Mars airplane mission at NASA’s Langley Research Center in Hampton, Va. He believes that a robotic, rocket-powered airplane is the perfect platform for unraveling the Red Planet’s biggest mysteries.
Soaring at an altitude of 1.6 kilometers, an airplane could cover hundreds of kilometers, gathering visual images and remote sensing data that it transmits back to Earth.

Joel Levine: Why we need to go back to Mars TED

At TEDxNASA, planetary scientist Joel Levine shows some intriguing — and puzzling — new discoveries about Mars: craters full of ice, traces of ancient oceans, and compelling hints at the presence, sometime in the past, of life. He makes the case for going back to Mars to find out more.

NASA Robotic Rocket Plane To Survey Martian Surface Popular Science

NASA wants a rocket-powered UAV to fly around the Red Planet, photographing the surface. The plane, repetitively named ARES (not to be confused with NASA’s shuttle replacement, also named ARES), would fly to Mars in a regular rocket. Once it reaches the fourth rock from the Sun, it would pop out of the capsule, deploy its wings, and fire the rockets for an hour-long flight through the Martian sky. During that flight, ARES would cover about 373 miles, which is a little less than 100 times the area covered by the Spirit rover over the last five years.

International Mars Scientists Gather in Williamsburg, Virginia NASA

NASA Langley Research Center will play host the world’s leading Mars scientists in Williamsburg next week, marking the first time that this international workshop on the Mars atmosphere has been held in the United States.
The atmosphere of Earth’s nearest planetary neighbor holds some of the keys to unlocking the secrets of Mars’ history. Was the climate ever suitable for sustaining liquid water on the Mars surface, and possibly even life? Studying the Martian atmosphere also provides a point of comparison for learning more about Earth’s meteorology, improves knowledge for future robotic and human missions and aids Langley researchers working on the nuts and bolts of Mars missions: entry, descent and landing.
