  1. Pre-Flight Briefing #1

    Post-Flight Launch Report Launch Time: 10:40 Members Present: Sean Preston, Justin Diehl, Nathan Kenney Play-By-Play: Used solid and liquid fuel boosters straight upwards until the rocket reached 60m/s, escaped atmosphere at around 10 degrees from horizontal, achieved orbit, and activated solar panels. Photographs: Time of Flight: 8m, 5s Summary: We were able to launch a satellite into orbit around Kerbin. Our rocket performed as expected. Opportunities / Learning: How to account for center of mass and weight of rocket components. Strategies: This achievement allows us more room to construct bigger and better rockets, including the possibility of a lunar mission. Milestone Awards: First working satellite placed in stable orbit - $80,000 Available Funds: $280,404

The thrusters have been upgraded to account for the increased mass of the payload. Launch Goals: We plan to get a remote controlled satellite into orbit around Kerbin. Pilot Plan: Similarly to our Copycat, we plan to use our solid fuel boosters to accelerate upwards, beginning to turn towards a 10 degree angle. We plan to detach the solid fuel boosters once they run out of fuel, and stage our main engine off once it runs out. Afterwards, our secondary thruster will allow us to reach a height allowing us to maneuver into orbit.
  3. Pre-Flight Briefing #1

    Post-Flight: Launch Time: 10:50 Play-by-Play: Rocket was able to escape the atmosphere. While ascent was shaky, stable orbit was achieved. A short EVA was performed once orbit was achieved. Photographs: Time-of-Flight: 0y, 0d, 00:07:30 Summary: The mission was a success. We achieved stable manned orbit, and performed an EVA. We faced the challenges of finding the correct angle to launch at in order to achieve our orbit, setting our course, and using thrust at the correct times. Opportunities / Learnings: The team learned that our momentum will carry us even if not using thrust, and how to use maneuvers to achieve the correct path. Strategies / Project Timeline: Achieving these goals gives us the funds to create larger rockets to reach further milestones Milestone Awards Presented: Achieving Stable Orbit - $40,000 Achieving Stable Manned Orbit - $50,000 First Kerbal EVA - $60,000 Available Funds: $221,779

  7. Holograms

    This post will delve less into video games and more into science fiction. Holograms are often shown in sci-fi movies and tv to show futuristic technology. Holograms are usually depicted as images created purely by light. Currently, we have digital projectors, able to display a color image on a flat surface. However, most holograms in pop culture have a 3d image. This would be difficult to accomplish realistically, since in order to create a 3 dimensional image, the light would need something to refract off of. The same way that a laser pointer will show a line through smoke or fog, but only shows a dot through the air. Creating a 3d hologram would require that light be refracted in specific regions in order to create an image. Figuring out a way to do this for a moving image, especially at a high framerate, would be difficult. I hope that one day technology advances to a point where I can see this happen.
  8. PaVG #23: Invisibility

    Usually, when someone asks what superpower you would want, some say invisibility. It may be possible in the future to achieve this, however. The idea behind cloaking, as many seem to point out in the comments of the video, is fairly simple: bending light around an object such that you are unable to see it. In my opinion, Team Fortress 2 does this very well. The Spy class has an invisibility watch that allows him to cloak himself for brief amounts of time. However, if the spy comes in contact with an enemy or takes damage, his cloak will "blink" and an outline of his body will become visible. This makes some sense, as the cloaking device in the video requires careful calibration of the lenses in order to cloak an object, bumping into the spy might mess up his cloaking and cause him to blink.
  9. PaVG #22: Wall Jump

    The wall jump is a common term for the ability of a video game character to kick off of a wall to gain a bit of height. This technique is most common to platforming games, but can have its place in other genres. Usually, the character will jump between two parallel walls, but it is possible in some games to do a wall jump at a 90 degree corner. The most interesting thing about this is that it is technically possible. The trick relies on applying force on the wall and using momentum in order to push yourself up. Video game wall jumps are a bit less demanding on momentum, but nearly always show the character pushing off against a wall. It's interesting to see something some consider only possible in games done similarly in real life!
  10. PaVG #21: Metroid 2

    Metroid is a game known for its power ups. One of the lesser known ones from Metroid 2 for the Gameboy was the Spider Ball. This allows Samus, when curled up into a ball using her morph ball ability, to stick to walls and ceilings. Assuming that SR-388, the planet Metroid 2 takes place on, has gravity identical to ours, this power up would allow Samus to hold herself to walls with a force of over 882 newtons considering that the manual for Super Metroid lists her weight as 90 kilograms without her Power Suit.
  11. PaVG #20: Mario Kart 8

    Mario Kart 8 introduced a "zero gravity" feature where, in certain parts of tracks could be driven on upside down and sideways. This addition to the series is interesting though, as it isn't explained how this would function. The carts levitate above the track while in "zero gravity" mode, yet don't fall away from the stage. Also, while in this mode, you still have the ability to accelerate and decelerate. This should be impossible without some kind of force coming from the cart. Sure, there are some kind of thrusters, but these only visibly activate after using a speed item. Additionally, tracks at an angle to the force of gravity would have carts moving towards the force of gravity.
  12. PaVG #19: Mega Man

    The main bosses of the Mega Man series are known as "Robot Masters". Each one has a theme, and a level to go along with that theme. For example, Gravity Man from Mega Man 3. As his name suggests, this robot is themed after the idea of controlling gravity. However, this should not be physically possible. Gravity is the result of large masses, such as planets and moons. In the game, this robot's level consists of "gravity" fields where you can fall towards the ceiling instead of the floor. If this were truly gravity, the level would not be able to "switch" gravity in specific places. Realistically, this would probably be an extremely strong magnet, but then we'd have a second Magnet Man.
  13. PaVG #18: Stardew Valley

    Stardew Valley is a peaceful farming game in the same vein as Animal Crossing or Harvest Moon. Unlike these games, Stardew Valley runs on its own calendar rather than using a real life equivalent. Time in Stardew Valley is broken up into four seasons, with 28 days each. Each day has 24 hours, but a second in our time is equivalent to about a minute in Stardew Valley time. While this time difference is most likely for gameplay purposes, I'd like to discuss Stardew Valley as if the game took place on another planet. A year, one full revolution around our sun, would take about 44.8 hours in our time. Due to the exactness of the seasons in the game, the orbit of the planet would have to be nearly circular.
  14. PaVG #17: Ping

    Most anyone who plays online games can tell you that ping, also known as latency, is one of the main factors to a smooth gameplay experience. Ping is the amount of time it takes for the input from your keyboard, mouse, or controller to reach the server running the game. This is usually measured in milliseconds, and the lower your ping is, the better. Good ping relies on a good connection to the server. This is dependant mainly on your internet connection and distance from the server. You'd get better ping connecting to a server close to you rather than one on the other side of the globe. Due to the limitations of physics, the speed of light in a vaccuum is 3x10^8 meters per second. This means that no matter what, ping will always be limited by distance. Even with the best fiber optic internet connection, you'd still see characters jittering around the screen if you connect across the globe.
  15. RGB Lighting

    One day, I was bored at my computer and decided to take a closer look at my mouse. This mouse has RGB lighting, meaning it can change between whatever color you could think of. However, the way these colors are produced has an interesting relation to physics. This mouse contains three separate LEDs. One controls the amount of red light produced, one for green, and one for blue, as indicated by the term RGB. Together, if each LED outputs light with a certain brightness, they can form other colors in between the standard red green and blue. Back to the story, I picked up my mouse which had a yellow color at the time. I decided to shake it around a bit, and noticed that when I did, I could see red and green strips of light. This is explained by a property of light which shows that light of different colors travel at different speeds. For example, red light travels faster than blue light. Knowing how something works is one thing, but seeing firsthand how that effect is achieved is another.
