i feel like re: jonathan's camera, steve's reaction is way more focused on than jonathan's LITERAL CRIMES. like yes stevetommycarol like graffitied the movie theater and broke his camera, but jonathan... took illicit pictures of an underage couple THROUGH STEVE'S WINDOW. how would you feel? how would you react?

and jonathan never really faces any lasting consequences? he gets a new camera from steve. he eventually ends up with nancy. and nobody really finds out or punishes him for being a .... literal criminal....

meanwhile, steve reacting to it is treated like some huge thing bc he calls jonathan queer ?? like i get that it may be a little harder hitting considering the audience is (i think? i only know from the tumblr sample size) seems mostly queer, but context please. not excusing it, but it's the 80s during the height of the aids epidemic saur. and it's also easy to say things you don't necessarily mean in the heat of the moment. but guess what. he apologized. did jonathan?

other than that, name one thing that could actually categorize steve as someone who is Decidedly an Asshole. talking shit with his friends is such a non problem (do u not shit talk with ur friends...) and being popular doesn't mean shit unless there's evidence.

stop trying to give steve a redemption arc when he never needed ur absolution

The Future World and Humanity

In the way the world is progressing in the fields of science and technology, what will be the implications for humanity and this planet? Let's try to understand this. Firstly, we need to assess the changes happening on this planet. In the next hundred years, there will be a significant increase in the average temperature of the Earth and a rise in sea levels, in addition to changes in weather patterns. Coping with this changing environment will require dealing with severe shortages of human and animal deaths and food. The elimination of insects will affect all creatures, ultimately impacting human life, and the chain of human deaths will accelerate after a century.

According to research estimates, by 2050, the rising sea levels will cause many cities and islands near the sea to disappear from the Earth. The advent of robotic machines will result in the elimination of 50% of jobs, with every task being performed in a smart and autonomous manner.

Both robotics and technology will transform the nature of all industries, and there will be further advancements in drone flights, whether for civilian or military use, making human life easier. Human society will undergo a transformed society. Many languages spoken on Earth will become extinct and obsolete. Due to the advancement of technology, there will be an impact on human evolution, leading to changes in its structure. According to scientists' estimates, human race extinction will occur within a thousand years.

By 2025, according to a research estimate, there will be a 1.5% increase in the Earth's temperature compared to the pre-industrial era, and this will continue to rise unless addressed. The environment of 2050 will be very different from today's environment, with changes in education, income sources, and human living conditions. Due to scientific progress, means of income in the 21st century will be faster and more effective. Human means of income will be through rockets, providing better facilities for humans in space and becoming their new habitat. The dreams of the present era will become a reality in the next century.

Due to the advancement of scientific progress in medicine, there will be an impact on human health and lifespan, and diseases like cancer will become treatable. Patients will be able to receive treatment from doctors without leaving their homes, thanks to technology. The speed of computers will be many times faster than today's computers. With the advent of 3D printing technology, anything can be easily manufactured and molded according to its construction. Interactive holographic television will adorn homes by 2050, which can be activated with the press of a button on mobile phones, allowing for viewing 3D and virtual films.

In the current era, some jobs provide convenience with all information displayed in front of the driver's screen. In this era, students will no longer be seen carrying large bags for education; instead, they will carry tablets and laptops. All the syllabi of students will be available on them, freeing them from carrying heavy books. Touchscreens will replace blackboards, allowing teachers to create shapes easily. Future humans will strive to improve their defensive, mental, and physical abilities through technology, which will reduce the use of natural factors.

There are some positive developments in this human advancement, including the creation of new antibiotics and vaccines, and the establishment of democratic societies. However, when looked at negatively, a new era of nuclear weapons and fascism is also emerging. Environmental and societal changes indicate a fear of overcrowding by 2050, according to an estimate by the World Bank. Human evolution will continue as long as they continue to advance their race and protect it. Human evolution is affecting the current environment in three ways:

Increase in population rate,

Environmental changes, including smoke from burning petroleum products obtained from land and seas, and

Melting glaciers.

This is leading to deforestation, poor air quality, and the scarcity of clean drinking water. Human progress is showing its impact on the environment, such as changes in land construction, plant species, and the carbon cycle. Due to the increasing population and construction of buildings, there will be a shortage of agricultural land, affecting food shortages. Forests will start disappearing from the page of existence. According to scientists, this environmental change will lead to changes in human evolution and its structure.

Visible changes in humans, such as dense hair, large heads, and pronounced wrinkles, will occur. According to scientists' estimates, human race survival is visible only in such a vital environment for a thousand years. Otherwise, this race will be extinct even before that. Due to the earth's proximity to the solar orbit, the temperature will increase to an unbearable level. Significant changes are expected in the backs and necks of humans, and changes in the structure of their hands and eye sockets will also be visible.

And their structure will have undergone significant changes compared to the current human structure. There will be changes in the agricultural sector, and vertical farming will increase due to the scarcity of land. Tall buildings will be used for agriculture, and vertical farms and genetically modified crops and meats will be common. New fields of employment have already been introduced, such as space tourism companies, computer and genetic engineering fields, and experts in vertical agriculture. In addition, many other new fields of employment will emerge, while old fields will become obsolete. The world will be based on artificial intelligence, mobile cameras, and autonomous structures.

In the future, the focus of scientists' research will be on the moon and Mars. The world in which we live will undergo a transformed society after a century. Seasonal and temperature fluctuations will be more frequent and longer, leading to food shortages and droughts. Migration from one place to another will be faster, and the incidence of infectious diseases will increase. Environmental changes will occur rapidly. No scientist can predict the next century accurately; all these are speculations and scientific estimates.

Imagine a world of limitless possibilities with fusion, robotics, AI, and space mining. These technologies could provide us abundant clean energy, enhanced productivity, rapidly advancing science, and access to vast resources beyond our planet.

However, they could also be a curse if we let greed and profiteering corrupt them. History has shown us how unscrupulous corporations and individuals have exploited natural resources, workers, and consumers for their own gain, often with devastating consequences for the environment and human rights. Another risk of these technologies is that they could create or exacerbate power imbalances between different groups of people. Some companies, individuals, or governments could gain exponentially more power by controlling or monopolizing these technologies. At the same time, the general populace faces growing wealth inequality and shrinking power in democracies bought out by the powerful. This could undermine the political equality essential for a healthy democracy, as the wealthy and influential could use their resources and connections to sway policies and elections in their favour, while the poor and marginalized could be excluded or exploited by the system.

How can we prevent these scenarios from happening? We need to change course and adopt a more ethical and sustainable approach to innovation. We must ensure these technologies are used for the common good, not for private profit. We need to demand more transparency and accountability from the developers and users of these technologies. And we need to join forces with like-minded people who share our vision of a better future. We must ensure these technologies are democratized and accessible to all, not just to a few. We need to create a level playing field where everyone has a fair chance to benefit from these technologies and has a voice and a vote in how they are used and regulated. We need to hold those who abuse or misuse these technologies and protect the rights and interests of those affected by them.

What We Learned from Flying a Helicopter on Mars

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.

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.

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.
