On April 3rd, the Mars Ingenuity helicopter was removed from its carbon-fiber shield on the Perseverance rover’s belly. On Sunday, April 11th, it will make its first attempt at a powered, controlled flight, becoming the first aircraft to operate on another planet. In the meantime, Ingenuity accomplished another major milestone as it survived its first full night on the Martian surface.Continue reading “Mars Helicopter Survives its First Night on Mars is Getting Ready to Fly”
In two days (on Thursday, Feb. 18th, 2021), NASA’s Perseverance rover will land on Mars. As the latest robotic mission in the Mars Exploration Program (MEP), Perseverance will follow in the footsteps of its sister mission, Curiosity. Just in time for its arrival, research conducted at the Southwest Research Institute (SwRI) has shown that Mars’ surface was shaped by flowing water several million years earlier than previously thought.Continue reading “Water Shaped Features on Mars Much Earlier Than Previously Believed”

When NASA’s new Perseverance Martian rover launches in a little over a month it will have a small robotic stow-away on board. Ingenuity is a small helicopter, with a fuselage about the size of a softball and two extending rotors that measure about 4 feet across. It was attached to the bottom of the rover’s chassis in April, and NASA recently released details about it’s technically challenging release process.
Before the team of NASA and Lockheed Martin engineers started designing the release mechanism though, they had to decide what Ingenuity’s mission would actually be. Ultimately, the helicopter will serve as the first powered experimental test flight on any extraterrestrial body. NASA is hoping it will be the first of many, leading to future helicopters on Mars that could allow mission scientists to peer into previously inaccessible places, such as craters and cliffs, from the air. If Ingenuity is successful, it could pave the way to many future air based scientific and scouting missions.Continue reading “Here’s How Perseverance’s Helicopter Sidekick Will Deploy on Mars”
Flying low over the surface of Mars. Don’t tell me you haven’t dreamed about it, especially with some of the ‘Mars flyover’ videos that have been produced over the years using data from the orbital missions. And if all goes well – global pandemic not withstanding — a helicopter will be on its way to the Red Planet in just a few months.Continue reading “Mars Helicopter gets a Name: Ingenuity”
This summer, NASA’s Perseverance rover will launch from Cape Canaveral Air Force Base in Florida. When it arrives on Mars (on February 18th, 2021), it will join the Curiosity rover and a host of other missions that are looking for evidence of past and present life on the Red Planet. At present, engineers at the Kennedy Space Center in Florida are conducting the final assembly of the rover in preparation for launch.
With less than 14 weeks to go before the mission’s launch period opens up, several important development milestones have been completed. This includes integrating the rover’s remaining components, like the rover’s six wheels and the small helicopter drone that will help explore the surface. These elements, and a slew of other final preparations, were integrated with the rover over the past few weeks.Continue reading “Wheels and Helicopter Attached to Perseverance Rover”
Work on the Mars 2020 Rover is heating up as the July/August 2020 launch date approaches. Mission engineers just attached the Mars Helicopter to the belly of the rover, where it will make the journey to Mars. Both the solar-powered helicopter and the Mars Helicopter Delivery System are now attached to the rover.
NASA’s Mars Helicopter will be the first aircraft to fly on another planet. The small rotor-craft only weighs 1.8 kg (4 lbs.) and is made of lightweight materials like carbon fiber and aluminum. It’s largely a technology demonstration mission, and is important to NASA. The overall mission for the Mars 2020 rover won’t depend on the helicopter, but NASA hopes to learn a lot about how to proceed with aircraft on future missions by putting the Mars helicopter through its paces on Mars.Continue reading “Mars 2020 Rover Gets its Helicopter Sidekick”
NASA has pioneered the development of all kinds of robots and robotic systems. Beyond its0 orbiters and satellites, which have been exploring the planets and bodies of the Solar System for decades, there’s also the growing army of landers and rovers that have been exploring planetary surfaces. Aboard the ISS, they even have floating robots (like CIMON) and humanoid robot helpers – a la Robonaut and Robonaut 2.
Looking to the future, NASA hopes to build robots that can do even more. While the current generation of rovers can drive across the plains and craters of Mars, what if they could explore cliffs, polar ice caps and other hard-to-reach places? That is the purpose behind the Limbed Excursion Mechanical Utility Robot (LEMUR) that is currently being developed by engineers at NASA’s Jet Propulsion Laboratory.Continue reading “NASA is Building Robots That Can Climb Rock and Ice Cliffs”
We’ve known for some time that NASA is sending a helicopter to Mars. The vehicle, called the Mars Helicopter, is undergoing flight testing at NASA’s Jet Propulsion Laboratory in California. The little helicopter will make its eventual way to Mars as part of the Mars 2020 Rover mission.
The Mars Helicopter is pretty small, less than 1.8 kg (4 lb). It’s made of lightweight carbon fiber, and other materials like aluminum, silicon, and foil. The version being tested is the actual vehicle that will make the trip to Mars.Continue reading “Mars Helicopter Completes More Test Flights. It’s Almost Ready to go to Mars”
At present, there are over a dozen robotic missions exploring the atmosphere and surface of Mars. These include, among others, the Curiosity rover, the Opportunity rover, the Mars Orbiter Mission (MOM), the Mars Reconnaissance Orbiter (MRO), the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter, and the soon-to-arrive InSight Lander. In the coming decade, many more missions are planned.
For instance, NASA plans to expand on what Curiosity has accomplished by sending the Mars 2020 rover to conduct a sample-return mission. According to a recent announcement issued by NASA, this mission will also include the Mars Helicopter – a small, autonomous rotorcraft that will demonstrate the viability and potential of heavier-than-air vehicles on the Red Planet.
As NASA Administrator Jim Bridenstine declared in a recent NASA press release, this rotocraft is in keeping with NASA’s long-standing traditions of innovation. “NASA has a proud history of firsts,” she said. “The idea of a helicopter flying the skies of another planet is thrilling. The Mars Helicopter holds much promise for our future science, discovery, and exploration missions to Mars.”
U.S. Rep. John Culberson of Texas echoed Bridenstine statement. “It’s fitting that the United States of America is the first nation in history to fly the first heavier-than-air craft on another world,” he said. “This exciting and visionary achievement will inspire young people all over the United States to become scientists and engineers, paving the way for even greater discoveries in the future.”
The Mars Helicopter began as technology development project at NASA’s Jet Propulsion Laboratory (JPL), where it spent the past four years being designed, developed, tested and retested. The result of this is a football-sized rotorcraft that weights just under 1.8 kg (four pounds) and relies on two counter-rotating blades to spin at a rate of almost 3,000 rpm (10 times the rate of a helicopter here on Earth).
As Mimi Aung, the Mars Helicopter project manager at JPL, indicated:
“The altitude record for a helicopter flying here on Earth is about 40,000 feet. The atmosphere of Mars is only one percent that of Earth, so when our helicopter is on the Martian surface, it’s already at the Earth equivalent of 100,000 feet up. To make it fly at that low atmospheric density, we had to scrutinize everything, make it as light as possible while being as strong and as powerful as it can possibly be.”
This concept is ideal for navigating through Mars’ thin atmosphere, where the mean surface pressure is about 0.6% that of Earth’s at sea level (0.60 kPa compared to 101.3 kPa). This low-flying helicopter would not only be able to increase the range of a rover, it will be able to explore areas that the rover would find inaccessible. As Thomas Zurbuchen, the Associate Administrator for NASA’s Science Mission Directorate, explained:
“Exploring the Red Planet with NASA’s Mars Helicopter exemplifies a successful marriage of science and technology innovation and is a unique opportunity to advance Mars exploration for the future. After the Wright Brothers proved 117 years ago that powered, sustained, and controlled flight was possible here on Earth, another group of American pioneers may prove the same can be done on another world.”
Other capabilities that make it optimized for Mars exploration include lithium-ion batteries, solar cells to keep them charged, and heating mechanisms that will keep it warm during Martian nights – where average temperatures can get as low as 210 K (-63 °C; -82 °F) around the mid-latitudes. In addition, the helicopter is programmed to fly autonomously, since it cannot be flown in real-time (given the distances involved).
Commands will be issued from controllers on Earth, using the rover as a relay, who will instruct the helicopter to commence flight once it is ready to deploy. This will begin shortly after the rover arrives on the planet (which is expected to happen by February 2021) with the helicopter attached to its belly pan. The rover will then select a location to deploy the helicopter onto the ground.
After it is finished charging its batteries and a series of pre-flight tests are performed, controllers on Earth will relay commands to the Mars Helicopter to commence its first 30-day flight test campaign. This will include up to five flights that will take it to increasingly greater distances from the rover (up to a few hundred meters) for longer periods of time (up to 90 seconds).
On its first flight, the helicopter will make a short vertical climb to 3 meters (10 feet) where it will hover for about 30 seconds. Once these tests are complete, the Mars Helicopter will assist the rover as it conducts geological assessments and determines the habitability of its landing sight. The purpose of this will be to search for signs of ancient life on Mars and assesses the natural resources and hazards for future missions involving human explorers.
The rover will also conduct the first-ever sample-return mission from Mars, obtaining samples of rock and soil, encasing them in sealed tubes, and leaving them on the planet for future retrieval by astronauts. If all goes well, the helicopter will demonstrate that low-flying scouts and aerial vehicles can be a valuable part of any future missions. These will likely include robotic missions to Saturn’s largest moon, Titan, where researchers are hoping to explore the surface and atmosphere using helicopter (such as the Dragonfly concept).
The Mars 2020 mission is expected to reveal some very impressive things about the Red Planet. If the helicopter proves to be a viable part of the mission, we can expect that additional information and images will be provided from locations that a conventional rover cannot go.
