everybody tweets like a social theorist these days, blaming their sad little lives on the commodification of art, decline of third spaces, hyperindividualism, and other such nonsense. I, on the other hand, know what's causing my misery--the demiurge's curse

i remember adults telling me, as a kid, to listen to doctors and get my flu vaccine and any shots i could because they remembered Before.
then they started fighting Covid precautions.
i remember adults telling me, as a kid, that the ozone was disappearing and the earth was dying and we needed to recycle and save the planet.
now my parents think climate change is a myth.
i remember adults telling me, as a kid, that racism was a plague, that we had to love and accept everyone, that we should never judge before walking a mile in their shoes.
then they told me that protesting for my Black siblings was wrong.
i remember adults telling me, as a kid, that we needed to give to the poor. working at soup kitchens. making quilts. collecting food and money and supplies. building houses. because it was the christian and just plain right thing to do.
now they look at me, on food stamps with their grandchildren, and lament the "welfare state".
i remember adults telling me, as a kid, that it was easier for a camel to pass through the eye of a needle than a rich man to enter the Kingdom of Heaven and that any rich man, especially an immoral one, should never run our country.
you can guess who they voted for.
i remember adults telling me, as a kid, so very much.
when did they forget?

The most difficult part of hiding a sword, I imagine, would not be in the actual hiding, but in squashing down the phenomenal urge to tell absolutely everyone that you *HAVE* a SWORD

What We Learned from Flying a Helicopter on Mars
Tumblr media
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?
We can fly rotorcraft in the thin atmosphere of other planets.
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.
Tumblr media
Creative solutions and “ingenuity” kept the helicopter flying longer than expected.
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.

There is value in adding an aerial dimension to interplanetary surface missions.
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.
Tumblr media
Tech demos can pay off big time.
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.

You can fall in love with robots on another planet.
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.
