NASA has shared a video that not only shows the Ingenuity drone flying above Mars but also contains audio, allowing all to hear the sounds of the drone zipping through the air. It is the first time a spacecraft on another planet has recorded sounds from another spacecraft nearby.
As noted by NASA, “on April 30, 2021, NASA’s Perseverance rover made history as the first spacecraft to record sounds from another spacecraft on another planet.” The historic achievement came during Ingenuity’s fourth flight, and the microphone included on the SuperCam laser instrument aboard the Mars Perseverance rover captured the sound of the drone’s rotors through the muffled wind.
“The laser zaps rocks from a distance, studying their vapor with a spectrometer to reveal their chemical composition,” NASA explains in a press release. “The instrument’s microphone records the sounds of those laser strikes, which provide information on the physical properties of the targets, such as their relative hardness. The microphone can also record ambient noise, like the Martian wind.”
Ingenuity captured the below color photo during the flight, which is called “Airfield B” and will be its new landing site. The helicopter will seek to set down there on its fifth flight attempt.
Because the Perseverance was parked 262 feet from the Ingenuity’s takeoff and landing location, NASA wasn’t sure if the microphone would be able to pick up any sound from the flight. In the photo below which was captured by one of the hazard cameras on the Perseverance rover, you can see the Ingenuity in the distance.
“Even during flight, when the helicopter’s blades spin at 2,537 rpm, the sound is greatly muffled by the thin Martian atmosphere,” NASA continues. “It is further obscured by Martian wind gusts during the initial moments of the flight. Listen closely, though, and the helicopter’s hum can be heard faintly above the sound of those winds.”
Scientists made the audio, which is recorded in mono, easier to hear by isolating the 84-hertz helicopter blade sound, reducing the frequencies below 80 hertz and above 90 hertz, and increasing the volume of the remaining signal.
“Some frequencies were clipped to bring out the helicopter’s hum, which is loudest when the helicopter passes through the field of view of the camera,” the organization adds.
The gif below shows the Ingenuity helicopter’s movement as seen from its down-facing navigation camera. The camera, which tracks surface features below the helicopter, takes images at a rate at which the helicopter’s blades appear frozen in place, despite making 21 full rotations in-between each image. In flight, the blades spin at 2,537 rpm. The images are aligned entirely using Ingenuity’s on-board position tracking system highlighting the stability and accuracy of the navigation algorithm.
“This is an example of how the different payload instrument suites complement each other, resulting in information synergy,” said Soren Madsen, Perseverance payload development manager at NASA’s Jet Propulsion Laboratory in Southern California. JPL built Perseverance as well as Ingenuity and operates both of them. “In this particular case, the microphone and video let us observe the helicopter as if we are there, and additional information, such as the Doppler shift, confirms details of the flight path.”
The Perseverance and Ingenuity are making history. In addition to capturing the first sounds of a spacecraft from another spacecraft, the Ingenuity is also the first helicopter drone to make a powered, controlled flight on another planet, during which it sent back its first photo.

The Kokga Tbilisi Awards, now in its 20th year, is the largest and most prestigious photo competition in the country of Georgia. Not to be confused with the state of Georgia, the awards intend to link international photography to Georgia.
The organizers of the Kolga Tbilisi photo competition have been hosting the presentation of the winners in Cologne, Germany as part of its intent to foster the international position of Georgia. This year’s competition was judged by an international jury: Vanessa Winship and George Georgiou, both photographers from the U.K. were joined by Tina Schelhorn, the curator of the Galerie Lichtblick, Kolga Tbilisi Photo in Germany, Stefen Chow, a photographer from China, and Jens Friis, a publisher from Denmark.
This year’s competition broke out into five categories: Documentary Series, Reportage, Conceptual Photo Project, Best One Shot, and Mobile Photo – One Shot.
Entry fees were used to fund for the winners’ prize fund, a total of $6,500. The winners in the first three categories received $1,500 each, the Best One Shot winner received $1,000, and the Mobile Photo – one shot category winner received $500.
Below are the winning images from each category.
Photographer Emily Ducke was crowned the winner of the Documentary Series category for the series titled “The River Between.”
“The Ket River was once a major Siberian thoroughfare. Though serpentine and relatively small, it connected two of Russia’s biggest river basins, the Ob and Yenisey. In a region where extremes of weather turn overland roads from inaccessible ice to muddy rubble and back, and where driving distances are measured in days and weeks, the corridor the Ket River created was a key resource.
“But when the Trans-Siberian railway was built, at the start of the previous century, west-to-east traffic on the Ket River – the farmers and traders and Tsarist troops – began to dwindle.
“Fewer and fewer travelers needed the Ket, and today its banks are home to just a few scattered and solitary settlements.”
Photographer Alessio Paduano took top honors in this category for his series documenting the Coronavirus pandemic in Italy.
“February 21, 2020 is a central date for the Italian story related to the new coronavirus. On this date, several cases of coronavirus emerged in the Lodi area of Lombardy: these are people who do not come from China, a new outbreak whose extent is still unknown. The infection has spread to Italy, especially in the North, but also begins in other regions. On March 9, 2020 the Italian Prime Minister Giuseppe Conte, during a speech to the nation declares the entire Italian territory a “protected area”. On March 11, 2020 “World Health Organization” general director Tedros Adhanom Ghebreyesus announced in the Geneva briefing on the coronavirus epidemic that Covid-19 “can be characterized as a pandemic situation”.
“Italy remains one of the deadliest hot spots of the coronavirus pandemic. As of March 5, 2021 more than 99,000 people have died in the country, according to Johns Hopkins University.”
Conceptual Photo Project
The Conceptual photo category hosted two winners: Jennifer Crane for her series “Outlaw (and other failed portraits)” and Andrea Pietro Signori for “Suspended: The rural life of Syrian refugees in Marjayoun in the middle of the Lebanese crisis.”
First, Crane’s series:
“I consider the portrait as a trace of the body or performance for the lens. Since its inception, the photographic portrait has been used to honor or vilify the human subject. Initially my interest was in exploring family portraits this led to further explorations into portrait photographs in the public context such as museums, institutional archives and in the news media. In these images I pose my own body before the lens using a long exposure of several minutes rather than the conventional fraction of a second. They are made using wet collodion one of the first photographic processes that requires the light sensitive emulsion to stay wet while exposure is made resulting at times in presence of liquid residue markings that interrupt the surface of the image and draw attention to the materiality of photograph which in most portraits remains invisible. Through the creation of this fictional archive I seek to engage with issues of surveillance, memory, authenticity and archival practices.”
And next, Signori’s series:
“The crisis that has hit Lebanon put on knees Syrian communities. This is the case of Marjayoun where about 5000 Syrian refugees live since the war broke out in Syria in March 2011.
“Along the border between Lebanon, Israel and Syria, 860 families live in 74 informal camps.
“The families are often numerous, with many children whose majority was born in Lebanon. They live on agriculture, serving as laborers in the service of Lebanese landowners. The salary ranges from 4000 to 5000LL which is gradually losing purchasing power. As reported by Avsi, one of the NGOs in the area, people are suffering the consequences of the heavy inflation. Since the revolution broke out the official exchange rate of 1$=8000 LL (variable every day) has been joined by a parallel market.
“The concept involves the use of nylon used to cover furniture during the move. I wanted accentuate the refugees status, the political and work suspension and the expectations, by Syrian refugees, to come back home.”

It goes by a few names: the “Skinny House,” the “House Full of Stairs,” the “Pez Dispenser,” “A Truly One-Of-A-Kind Architectural Masterpiece” (OK, that last one, taken from the house’s listing, might be a little biased). Now, after nearly three years on the market, and with just as many price reductions, someone is finally calling it their home.Toronto’s Skinny House is four storeys tall and just over 1,300 square feet. It has three bedrooms, three bathrooms, floor-to-ceiling windows and a whole lot of stairs. On April 20, it sold for $1.75 million, just over half its initial asking price of about $3 million in 2018.The house at 154 Hamilton St. is unlike anything in its surroundings. Unusually tall, thin and modern, it was built back from the curb and towers over...
