How did NASA just fly a helicopter on Mars?


NASA Literally just flew a helicopter on Mars, but how? Many people on Twitter were suggesting it was fake since there are no helicopter pilots on mars. Obviously, everyone laughed at them, and they were wrong. This helicopter, more like a drone, was not manually flown/controlled due to obvious reasons & a time delay from radio waves from us to Mars. It was powered by its onboard computer and gets electricity from its solar panels. This helicopter is called ingenuity.

It was launched last year on ULA'S Atlas V Rocket along with the Perseverance Rover, which you can see in the background of the image above on the left side. Ingenuity wasn't easy to make & have fly. It's rotors/blades are made from carbon fiber, a high strength but extremely light material, also used in the aerospace industry on almost any rocket for COPV's, or composite overwrapped pressure vessels.

Ingenuity needed to be very lightweight since Mars' atmospheric pressure is way below 0.1 bar/atm (0.1% of Earth's atmospheric pressure). This means there would be way less air to suck in through the top and push down. This would also be more difficult because Mars' Atmosphere, as little as it is, consists of almost entirely Co2, aka Carbon Dioxide. Carbon Dioxide is denser than Nitrogen, which is more than 70% of the air we breathe & is all around us.

Ingenuity successfully & autonomously lifted off this morning at 3AM, and landed. We didn't get the info back that it had lifted off and landed until around 6AM because of the radio wave time delay. This is where laser communications come in. More on that in our next blog post. Thanks for reading.

Starship SN10 Aborts at T - 0 Seconds for its 10km test flight.

  Moments ago, Starship SN10 attempted a flight to 10km, to then orient itself into a unique horizontal bellyflop position, flip itself upright after it has descended to about 1km, deploy the landing legs, and touch down on the landing pad softly. This vehicle, Starship Number 10, uses Liquid CH4 (methane) and Liquid Oxygen aka LOX/LO2, used by its 3 powerful Raptor engines.  Today, SpaceX started their official stream for the Starship SN10 Flight. SpaceX have privated the stream replay, so we cannot replay it. In case you want the link: The vehicle began fueling up with Methane and LOX, and then shortly after, it started the engine chill process, which is the process of chilling the engines down in preparation for engine ignition, so the engine material does not crack or get damaged from sudden shock. The vehicle attempted to start up its 3 Raptor engines, by opening the fuel & oxidizer valves, starting up the turbopumps, sho

What is “the best” programming language?

Programming languages, there are so many of them. Some programming languages are way easier to learn than other ones. But which programming language, is “the best” programming language? This question, it is not really answerable. There is no “best programming languages”, they are all meant for different things, well, MOST of them. If I were to compare 2 different programming languages, meant for very similar things, like Batch and Bash, I would say Batch is easier, as its Syntax is not as confusing as Bash’s to the average person. Here is another example, C# is primarily used for computer applications, mostly on Windows, and HTML is a markup language, being used to make websites. I cannot compare C# (it is pronounced “See Sharp” if you didn’t know) because they are used for completely different things. It wouldn’t make sense to say, “C# is way better”, because what is it better at? Developing desktop applications? Sure! Then I can say HTML is better at making websites, it is not a logi

How do you know the universe was not created a few minutes ago?

       The universe is the giant area of space that we live in, which is observable. Anything past our universal border is not in our universe. People do say the universe is constantly expanding, but there is no proof of that, as the "imaginary" or, maybe not imaginary border at the "end" of our universe. But, how do you know that the universe even exists? Were you even in it last week? Did last week even exist? Last week, the universe could have been created, and you do not have proof against it. All of your knowledge and memory could have easily popped into existence a few seconds ago, tricking you into thinking you have existed for longer than you think. This is likely, but also unlikely, it is a 50/50 chance. A reason that this is unlikely is, there are a lot of things that do not make sense in our universe. Like, why does matter attract matter, resulting in gravity? This exists in our universe, but can it exist in a different universe? Not really, or most likel
