I want owned physical media back, but I'm not sad to see DVDs go – optical media was always a transitional technology, and suffers from a number of intractable drawbacks. I want them to start selling movies on indestructible solid-state cartridges the size of a quarter, so I can keep my entire media collection in an unsorted pile in a random cabinet drawer and have to go rummaging through it like an amateur chef trying to find the lemon zester every single time I want to watch something. Do you understand? I want to lose the entire Star Wars trilogy between my couch cushions.

Okay, so this is my try to make aesthetic frutiger aero aquarium monitor. It's not best creation, but I did my best. There's so much to learn.

The Ingenuity Mars Helicopter made history – not only as the first aircraft to perform powered, controlled flight on another world – but also for exceeding expectations, pushing the limits, and setting the stage for future NASA aerial exploration of other worlds.
Built as a technology demonstration designed to perform up to five experimental test flights over 30 days, Ingenuity performed flight operations from the Martian surface for almost three years. The helicopter ended its mission on Jan. 25, 2024, after sustaining damage to its rotor blades during its 72nd flight.
So, what did we learn from this small but mighty helicopter?
Ingenuity proved that powered, controlled flight is possible on other worlds when it took to the Martian skies for the first time on April 19, 2021.
Flying on planets like Mars is no easy feat: The Red Planet has a significantly lower gravity – one-third that of Earth’s – and an extremely thin atmosphere, with only 1% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.
Ingenuity performed several flights dedicated to understanding key aerodynamic effects and how they interact with the structure and control system of the helicopter, providing us with a treasure-trove of data on how aircraft fly in the Martian atmosphere.
Now, we can use this knowledge to directly improve performance and reduce risk on future planetary aerial vehicles.
Over an extended mission that lasted for almost 1,000 Martian days (more than 33 times longer than originally planned), Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, dusted itself off after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.
Fun fact: To keep costs low, the helicopter contained many off-the-shelf-commercial parts from the smartphone industry - parts that had never been tested in deep space. Those parts also surpassed expectations, proving durable throughout Ingenuity’s extended mission, and can inform future budget-conscious hardware solutions.
Ingenuity traveled to Mars on the belly of the Perseverance rover, which served as the communications relay for Ingenuity and, therefore, was its constant companion. The helicopter also proved itself a helpful scout to the rover.
After its initial five flights in 2021, Ingenuity transitioned to an “operations demonstration,” serving as Perseverance’s eyes in the sky as it scouted science targets, potential rover routes, and inaccessible features, while also capturing stereo images for digital elevation maps.
Airborne assets like Ingenuity unlock a new dimension of exploration on Mars that we did not yet have – providing more pixels per meter of resolution for imaging than an orbiter and exploring locations a rover cannot reach.
Ingenuity was flown as a technology demonstration payload on the Mars 2020 mission, and was a high risk, high reward, low-cost endeavor that paid off big. The data collected by the helicopter will be analyzed for years to come and will benefit future Mars and other planetary missions.
Just as the Sojourner rover led to the MER-class (Spirit and Opportunity) rovers, and the MSL-class (Curiosity and Perseverance) rovers, the team believes Ingenuity’s success will lead to future fleets of aircraft at Mars.
In general, NASA’s Technology Demonstration Missions test and advance new technologies, and then transition those capabilities to NASA missions, industry, and other government agencies. Chosen technologies are thoroughly ground- and flight-tested in relevant operating environments — reducing risks to future flight missions, gaining operational heritage and continuing NASA’s long history as a technological leader.
Following in the tracks of beloved Martian rovers, the Ingenuity Mars Helicopter built up a worldwide fanbase. The Ingenuity team and public awaited every single flight with anticipation, awe, humor, and hope.

Millions of people around the globe will come together for the Paris 2024 Olympic Games later this month to witness a grand event—the culmination of years of training and preparation.
Fifty-five years ago this July, the world was watching as a different history-changing event was unfolding: the Apollo 11 mission was landing humans on the surface of another world for the first time. An estimated 650 million people watched on TV as Neil Armstrong reached the bottom of the ladder of the lunar module on July 20, 1969, and spoke the words, “That’s one small step for [a] man, one giant leap for mankind.”
While the quest to land astronauts on the Moon was born from the space race with the Soviet Union during the Cold War, this moment was an achievement for the whole of humanity. To mark the world-embracing nature of the Moon landing, several tokens of world peace were left on the Moon during the astronauts’ moonwalk.
These words, as well as drawings of Earth’s western and eastern hemispheres, are etched on a metal plaque affixed to a leg of the Apollo 11 lunar lander. Because the base of the lander remained on the Moon after the astronauts returned, it is still there today as a permanent memorial of the historic landing.
Another artifact left on the Moon by the Apollo 11 astronauts is a small silicon disc etched with goodwill messages from leaders of 74 countries around the world. Each message was reduced to be smaller than the head of a pin and micro-etched on a disc roughly 1.5 inches (3.8 cm) in diameter. Thailand’s message, translated into English, reads: "The Thai people rejoice in and support this historic achievement of Earth men, as a step towards Universal peace."
Curious to read what else was inscribed on the disk? Read the messages.
The olive branch, a symbol of peace and conciliation in ancient Greek mythology, also found its way to the Moon in July 1969. This small olive branch made of gold was left on the lunar surface during Neil Armstrong and Buzz Aldrin’s 2.5-hour moonwalk. The olive branch also featured on the Apollo 11 mission patches sewed on the crew’s spacesuits. Designed in part by command module pilot Michael Collins, the insignia shows a bald eagle landing on the Moon holding an olive branch in its talons.
As NASA’s Artemis program prepares to again land astronauts on the Moon, including the first woman and the first person of color, this time we’re collaborating with commercial and international partners. Together we will make new scientific discoveries, establish the first long-term presence on the Moon, and inspire a new generation of explorers.

"There was an exchange on Twitter a while back where someone said, ‘What is artificial intelligence?' And someone else said, 'A poor choice of words in 1954'," he says. "And, you know, they’re right. I think that if we had chosen a different phrase for it, back in the '50s, we might have avoided a lot of the confusion that we're having now." So if he had to invent a term, what would it be? His answer is instant: applied statistics. "It's genuinely amazing that...these sorts of things can be extracted from a statistical analysis of a large body of text," he says. But, in his view, that doesn't make the tools intelligent. Applied statistics is a far more precise descriptor, "but no one wants to use that term, because it's not as sexy".

ABACUSYNTH by ELIAS JARZOMBEK [2022]
Abacusynth is a synthesizer inspired by an abacus, the ancient counting tool used all around the world. Just like an abacus is used to learn the fundamentals of math, the Abacusynth can be used to explore the building blocks of audio synthesis.
