NASA has announced that it is preparing to launch its Ingenuity Mars Helicopter no earlier than April 8. Ingenuity’s maiden flight will mark the first attempt at a powered, controlled flight of an aircraft on another planet. Before Ingenuity can lift off, the team must meet numerous challenging milestones.
The Mars Perseverance Rover landed on Mars on February 18. Since then, the rover has been sending important images and data back to Earth while the team goes through different instrument checks and testing procedures. Since then, the Ingenuity Mars Helicopter has remained attached to the belly of Perseverance.
However, the operation has experienced progress. On March 21, Perseverance deployed the ‘guitar-case shaped graphite composite debris shield’ that protected Ingenuity when Perseverance landed last month. Perseverance is now in transit to the ‘airfield’ where Ingenuity will attempt to fly. After Ingenuity is deployed, the helicopter will have 30 Martian days, known as sols, to perform its test flight campaign. This is equal to 31 Earth days.
”When NASA’s Sojourner rover landed on Mars in 1997, it proved that roving the Red Planet was possible and completely redefined our approach to how we explore Mars. Similarly, we want to learn about the potential Ingenuity has for the future of science research,’ said Lori Glaze, director of the Planetary Science Division at NASA Headquarters. ”Aptly named, Ingenuity is a technology demonstration that aims to be the first powered flight on another world and, if successful, could further expand our horizons and broaden the scope of what is possible with Mars exploration.”

It’s difficult enough to get a helicopter to Mars, and that accomplishment is the result of years of work by many talented people and considerable financial resources. When designing Ingenuity, the team had to ensure it was small and light enough to be an acceptable payload for Perseverance. The helicopter is solar-powered, and it must be efficient enough to have the required energy to operate on Mars and survive cold Martian nights.
There are significant challenges to flying on Mars. The Red Planet has about one-third of Earth’s gravity, for starters, and the atmosphere is also only 1% as dense as Earth’s at the surface. The weather poses unique challenges, with nighttime temperatures dropping to -130° F (-90° C), which can wreak havoc on electrical components.
”Members of the NASA Mars Helicopter team inspect the flight model (the actual vehicle going to the Red Planet), inside the Space Simulator, a 25-foot-wide (7.62-meter-wide) vacuum chamber at NASA’s Jet Propulsion Laboratory in Pasadena, California, on February 1, 2019.’ Caption and image credit: NASA/JPL-Caltech
”Every step we have taken since this journey began six years ago has been uncharted territory in the history of aircraft,’ said Bob Balaram, Mars Helicopter chief engineer at NASA’s Jet Propulsion Laboratory in Southern California. ‘And while getting deployed to the surface will be a big challenge, surviving that first night on Mars alone, without the rover protecting it and keeping it powered, will be an even bigger one.’
Once Ingenuity is in place, squarely in the center of its 33′ x 33′ (10m x 10m) airfield, the complicated deployment process can begin. ”As with everything with the helicopter, this type of deployment has never been done before,’ said Farah Alibay, Mars Helicopter integration lead for the Perseverance rover. ‘Once we start the deployment there is no turning back. All activities are closely coordinated, irreversible, and dependent on each other…’
‘NASA’s Mars Perseverance rover’s descent stage was recently stacked atop the rover at Kennedy Space Center, and the two were placed in the back shell that will help protect them on their journey to Mars. In this image, taken on April 29, 2020, the underside of the rover is visible, along with the Ingenuity helicopter attached (lower center of the image). The outer ring is the base of the back shell, while the bell-shaped objects covered in red material are covers for engine nozzles on the descent stage. The wheels are covered in a protective material that will be removed before launch.’ Image and caption credit: NASA/JPL-Caltech
If all goes according to plan, the deployment process will take six sols. On the sixth scheduled sol of the deployment phase, NASA states that ‘the team will need to confirm three things: that Ingenuity’s four legs are firmly on the surface of Jezero Crater, that the rover did, indeed, drive about 16 feet (about 5 meters) away, and that both helicopter and rover are communicating via their onboard radios. This milestone also initiates the 30-sol clock during which time all preflight checks and flight tests must take place.”

Ingenuity is not carrying special instruments, and unlike the rest of the mission, its goals are not scientific. Ingenuity is solely an experimental engineering test flight. The team wants to see if it can fly on Mars. When Ingenuity is ready to fly, JPL mission controllers will send and receive flight instructions through Perseverance. Hopefully, early next month, Ingenuity will successfully launch from Mars’ surface. When it does, it will mark a monumental achievement for NASA, JPL and countless others.

If you haven’t signed up for the free DPReview newsletter, you’re missing out. It’s more than a recap of the website; we regularly share behind-the-scenes information, reader questions of the week, photo challenges and exclusive stories that can only be found in the newsletter.
In the last three months, we have given newsletter readers early sneak peeks at our testing, talking about our studio scene, product studio and what’s going on in the DPReview mail room (you never know what might be dropping by). We also give newsletter readers an exclusive heads-up on what’s happening around our office, complete with candid sharing of what the DPReview editors are thinking about and debating. Sometimes, we even let slip which camera review we’re working on and if it is coming out the following week.
Last month, the newsletter also hosted DPReview Camera Debate Madness of March (and part of April). Readers and editors weighed the choices between primes and zooms, lens-focusing design, viewfinder- or touchscreen-only cameras, and more. After four rounds of debates and voting, we crowned a champion and experience trumped gear lust. Relive every play-by-play to discover who won and how. Join our next event by signing up for the newsletter.
There’s also our ongoing ‘Question of the Week’ segment, where we turn the microphone toward you. Last week, we asked: What’s the perfect portrait lens, and why? Nearly 100 readers wrote in to share their takes, and every week, we share some of our favorite responses in the following newsletter. What did people have to say? Sign up to find out. Join us by answering our next question every week. This week, we’re asking you: If you could update one camera from the past and bring it back to the market, what would it be?

7Artisans has released a new manual focus 50mm F1.4 Tilt lens, compatible with Sony and Fujifilm APS-C cameras, as well as Olympus and Panasonic Micro Four Thirds cameras.
The new 50mm lens is made up of seven elements in six groups and has 12 aperture blades. It has a minimum focusing distance of 0.5m (19.6″) and weighs 364g (12.8oz). 7Artisans states the lens has a full metal build but does not mention weather sealing.
At the front of the lens is a numbered aperture ring, with the depth of field scale and distance scale focus ring sitting just behind. Users can rotate the lens a full 360-degrees and the tilt axis moves left to right. The company has yet to confirm how many degrees the lens can tilt on either side.
Although photographers commonly use tilt lenses for architecture photography and to experiment with depth of field, 7Artisans claims the 50mm F1.4 offers enough clarity for portraiture, claiming distortion of only 1.9%.
Search engines will likely confuse the new 7Artisan lens with another 50mm F1.4 tilt lens made by TTArtisan. Although similar brand names, they’re two separate companies, so it’s worth confirming who you’re buying from should you decide to purchase either lens.
Pricing and availability
The new 50mm F1.4 tilt lens is now available from 7Artisan’s website and Amazon at a suggested retail price of $226, and could be an affordable option for those looking to be more creative with their photography.
