  1. School's been treating me well it's definitely been a lot more work than high school, but manageable and enjoyable.
  2. A partial derivative uses this nice formula. (f)/(x), where f:R^2->R is lim h->0 (f(x+h,y)-f(x,y))/h. Physics is everywhere, waiting, watching.
  3. Launch Report and Debrief Launch Time: 10:32 Team Members Present: Jason Stack, Marcus NIcholas, Michael Kennedy Play-by-Play: We've lifted off and are headed directly up in an attempt to obtain orbit around Kerbin. We then angle our ship slightly to the east to increase the eccentricity of our orbit. We reached 70,000 meters and now a maneuver is being created to obtain orbit around Kerbin. Our first engine has been decoupled. Orbit has been obtained around Kerbin. We have waited a long time to obtain the proper angular distance from Duna. Now a maneuver is being used to create an encounter with an orbit around Duna. An encounter has been created with an orbit around Duna. We have obtained orbit around Duna. Our second set of engines have been decoupled. Now a maneuver is being created so that we can be pulled into Duna's atmosphere. Now we are attempting to land the ship. We have landed on Duna. Now a memorial flag is being placed on the planet in memory of Valentina. Now we are accelerating off of Duna's surface and a maneuver has been used to obtain orbit around Duna. Now a maneuver is being used to encounter Kerbin. An encounter has been created and we are going back to Kerbin. Orbit has been obtained around Kerbin. Now another maneuver is being used to pull us into Kerbin's atmosphere. We decoupled our last engine and are being pulled toward Kerbin's surface. Our parachute has been deployed. We have landed safely on Kerbin. Photographs: Valentina's Memorial Flag Reads: Forever in Memory Time-of-Flight: 2 years, 153 days, 12:22:31 Summary: We accomplished our goal which was to plant a memorial flag on Duna for Valentina. We accomplished this goal and returned safely back to Kerbin. Opportunities / Learnings: We've tested our rocket design that was used to reach Minmus and now Duna and it has been successful twice. We need to improve our landing gear so that it is easier to land on more difficult planets. Strategies / Project Timeline: Our next goal is to reach a further planet to test our rockets ability. Milestone Awards Presented: We orbited Duna and landed on Duna with a safe return. Available Funds: $3,743,188
  4.

Total cost = $82,090 Design Goals: Our vehicle is designed to venture to Duna and plant a memorial flag in memory of Valentina Kermin. Launch Goal: We plan to accomplish this mission and milestones for landing on Duna. We also hope to receive a 100% for this project by planting a flag on Duna. Pilot Plan: We will launch from the platform and initially head straight up into the air. A maneuver is expected to be used to obtain orbit around Kerbin. At about 70,000 meters, this maneuver will be made to get orbit. After obtaining orbit, we will create another maneuver so that we have an encounter with Duna's orbit. We will gain orbit around Duna. Then we will do another maneuver so that Duna can pull in our rocket so that we can land on Duna. After landing we will exit the ship and place a memorial flag on Duna for Valentina.

An encounter has been created with an orbit around Minmus. We have obtained orbit around Minmus. Our second set of engines have been decoupled. Now a maneuver is being created so that we can be pulled into Minmus's atmosphere. Now we are attempting to land the ship. It is made difficult by Minmus's very small gravitational pull, but we have landed on Minmus despite. Now we are leaving Minmus, immediately turning to the east, attempting to obtain an orbit around Minmus. We have created an orbit around Minmus. Now we are creating a maneuver to encounter an orbit with Kerbin. An encounter has been created and we now are orbiting Kerbin. We have created another maneuver to pull the ship into Kerbin's atmosphere. Our last engine has been decoupled. We are approaching the surface of Kerbin. Our parachute has been deployed and we are slowing down. We have successfully landed on Kerbin and completed our mission. Photographs: Time-of-Flight: 153 days 4:55:03 Summary: We successfully landed on Minmus and back on Kerbin afterward. Our flight consisted of many maneuvers to obtain orbits around Minmus and Kerbin and encounters between the two. We had no casualties and successfully maneuvered the difficulty of landing on Minmus. Our rocket design proved to be the proper design for what we accomplished seeing as we were able to land on Minmus and return to Kerbin safely and successfully. Opportunities / Learnings: We learned how to design a ship that is able to land on different moon's and planets and also able to carry enough fuel to return to Kerbin safely. Strategies / Project Timeline: Now that we have confidence in our ship design, we plan to explore different planets in Kerbin's solar system. Our next conquest will hopefully be a neighboring planet. Milestone Awards Presented: We were awarded $300,000 for landing on Minmus and successfully returning to Kerbin. Available Funds: After the launch we now have $475,728 in available funds.
  6. Pre-Flight Briefing Team Name: Nicholas Enterprises Available Funds: $257,818 Vehicle Name: Mr. Rocket Vehicle Parts List and Cost: Twin boar x2, MK3 Fuselodge x1, Rhino Engine x1, AVT-1 Winglet x1, Rockomax Decoupler x1, Airstream Protective Shell x1, TR-18 Stack Decoupler x2, Terrier Fuel Engine x1, F1-T 400 Tank, RC 0015 RGU x1, MK-1 Command Pod x1, SPL solar panel x2, MK16 Parachute x1, LT-1 Landing Struts x3, MK-7 Nose Cones x2, Launch Stability Enhancers x2, and Radial Decouplers x2.

Launch Goal: We expect to achieve the milestone of landing on Minmus with a safe return to Kerbin. We hope to demonstrate that we have the capacity to land on minmus safely and return to Kerbin successfully. Pilot Plan: A maneuver is expected to be used to obtain orbit around Kerbin. At about 70,000 meters, this maneuver will be made to get orbit. After obtaining orbit, we will create another maneuver so that we have an encounter with Minmus' orbit. We will gain orbit around Minmus. Then we will do another maneuver so that minmus can pull in our rocket so that we can land on minmus. After landing we will created another maneuver to orbit Minmus. Then we will use another maneuver to encounter an orbit around Kerbin. Once orbit around Kerbin is obtained, we will create a maneuver so that we are pulled into Kerbin's atmosphere. Then we will land the ship safely on Kerbin.

Nicholas Enterprises Starting Funds: $60,000 Vehicle Name: Mr. Rocket Vehicle Parts and Cost: MK16 Parachute X1, LV-909 Liquid Fuel Engine X1, FL-T800 Fuel Tank X1, TT-38K Radial Decoupler X3, RT-10 Hammer Fuel Booster X3, MK1 Command Pod X1, AV-T1 Winglet X3, TR-188 Stack Decoupler X2, Aerodynamic Nose Cone X3, FL-T400 X1, LV- T45 Engine X1. Total Cost- $12,182 Ending Funds- $47,818 Design Goals: Our rocket has been designed to successfully go into orbit around Kerbin and then return safely back to Kerbin. Launch Goal: Our goal for our launch is to go into orbit around Kerbin. Pilot Plan: The pilot should exit Kerbin’s atmosphere and then turn at the proper angle to cause the ship to go into orbit around Kerbin. Illustration: Launch Report and Debrief Launch Time: 10:37 am Team Members Present: Jason Stack, Marcus Nicholas and Michael Kennedy were all present for this launch. Play-by-Play: Initially the rocket was created using the parts listed in the pre-flight briefing. The rocket was launched from Kerbin and angled in order to successfully travel outside of Kerbin's atmosphere. The rocket was then directed into orbit around Kerbin. Kerbin was orbited a few times. The rocket was then returned back to Kerbin by using a maneuver that brought the rocket back into Kerbin's atmosphere. The bottom engines were released, then the second engines, leaving only the pod left. The pod descended to 1,000 meters above Kerbin and then the parachute was deployed. The pod landed safely on Kerbin. Photographs: Time-of-Flight: 4 hours and 5 minutes Summary: Our flight was a great success. We planned to accomplish all initial milestones, including a successful manned orbit and a successful Kerbal EVA. All of these desired milestones were accomplished. Our spaceship and Kerbal manning the ship returned safely to Kerbin after successfully reaching orbit around Kerbin. By reaching a manned orbit around Kerbin, all the initial milestones were accomplished by this launch. Opportunities / Learnings: Establishing what the launch goals are and designing the rocket accordingly is very important. Failure to do so will result in an inability to accomplish any milestones. Strategies / Project Timeline: After this accomplishment, our next goal is to reach orbit around the moon and land on the moon. Milestone Awards Presented: Launch to 10 km - $10,000 Manned launch to 10 km - $20,000 Manned launch to 50 km - $30,000 Achieving stable orbit - $40,000 Achieving stable manned orbit - $50,000 First Kerbal EVA - $60,000 Available Funds: $257,818

  10. In high school physics we've always been told that test will try to trick you. They'll ask if a 10kg person goes from the earth to the moon how will their mass change. And the answer is always it doesn't. Mass doesn't change, mass doesn't change, mass doesn't change. It's been hammered into our brains. But it's a lie. So the speed of light in a vacuum is 300,000 km/s. This is the fastest speed any object in the universe can travel at. So what happens if you try to accelerate an object going the speed of light? Well picture this: a rocket accelerate to the speed of light, but the thrusters are still pushing on the rocket. You might be tempted to say that the frictional force balances with the thrust of the rocket, so there's no net force. But then how would the rocket have accelerated to the speed of light? There must be a net force. Given that there is a net force, work is being done on the rocket. Therefore, there is a change in kinetic energy, but velocity isn't increasing. That means the other component of kinetic energy must be increasing: mass. In most cases mass is a constant, but when energy cannot be transferred into speed any longer, it has to be transferred into mass instead.

    That's super cool man!
  13. Black holes are often thought of as dark holes sucking matter in towards them by there massive amount of gravitational force. Interestingly enough, however, black holes are anything but black. Black holes might be dark, but they glow. It is well known that black holes decay until they don't have enough energy to sustain their mass, thereby not allowing them to exist any longer. But what does this loss of energy turn into? The slight glow in black holes. This slight glow is due to "Hawking Radiation". It is the slight decay of energy into radiation from black holes over the time of their existence. It is intriguing all the unknown facts about the universe and how much more is left to be discovered!
