  1. Jetpack Adventures with Jebediah Launch Time: 6/3/14 Team Members: All Play-by-Play: Got into orbit around Minmus (that's really all you need to know). From there, went on a fancy little EVA with Jeb, firing retrograde and trying to judge surface velocity by eye (no navball during EVA)! Managed to land successful with Jebediah alone on Minmus without any horrific accident, planted a flag, and managed to successfully rendezvous with our orbital craft without running out of fuel. Just sorta went on home from there. ...awww yeahhh... Time of Flight: About
  2. Team Name: Big & Low LLP Available Funds: $850 k, maybe (around there) Vehicle Name: Tricky Minmus (because it's so tricky) Parts List (& Cost): Command Pod Really small fuel tank 4 x Small Radial Engines Parachute 4 x Solar Panels Decoupler 2 x Those big fuel tanks Mainsail Engine Total Cost: I don't really know, I'll check (should be ~$30000 though - not very much) Design Goals: Get into orbit around Minmus. Why, you ask? Haven't we already done that? Yes, in fact, we have. But this time we're landing on it Without a ship! (Jetpack only) Launch Goals: Orbit around
  3. A Glorious Return Launch Time: 5/30/14 Team Members: All Play-by-Play: After the lack of fuel experienced by Jeb, it was time for us to go save him. As such, we had a perfect opportunity to practice both our interplanetary travel, and orbital rendezvous skills. Seeing as it was really only the landing on Duna that left us without enough fuel, we decided to reuse our previous craft, just stripped of landing gear and parachutes, with a remote control probe added in and an empty command pod. The goal was to get really close to Jeb's ship at a ~330 km orbit away from Duna, then simply
  4. Team Name: Big & Low LLP Available Funds: ~$500000 Vehicle Name: The Return of the King Parts List (& Cost): Command Pod Remote Control Unit "Poodle" engine 2 x Sorta medium fuel tank Parachute Decouplers Big fuel tank + Mainsail Engine 2 more Big fuel tank + Mainsail Total cost: ~$137000 Design Goals: Rescue poor stranded Jebediah, and return him back to Kerbin Launch Goals: Get to orbit, wait for optimal transfer to Duna, then head on over, rendezvous with Jeb, and come back Pilot Plan: Standard gravity turn to orbit, then wait for optimal transfer time/phase angle to
  5. The Sad (But Hopeful) Tale of Jebediah Kermin Launch Time: 5/28/14 Team Members: All Play-by-Play (pay attention kids): Everything was going just swell before Duna. Fuel was being drained as expected, and all was well. However, it seems guestimations on fuel just don't cut it, because, while technically right, we we're right on the margin. And human error is always a factor. Our initial goal was to aerobrake into Duna. Consulting my handy delta-v chart, I felt this would be all it took to land a craft on Duna, and we could ignore (most) of the delta-v on landing, giving us mo
  6. Team Name: Big & Low LLP Available Funds: ~$400000 Vehicle Name: Duna Lander Parts List (& Cost): Command Pod "Poodle" engine 2 x Sorta medium fuel tank Landing struts Parachute Decouplers Big fuel tank + Mainsail Engine 2 more Big fuel tank + Mainsail Total cost: ~$150000 Design Goals: Get to Duna! (and back of course) Launch Goals: Get to orbit, wait for optimal transfer to Duna, then head on over, land, and come back Pilot Plan: Standard gravity turn to orbit, then wait for optimal transfer time/phase angle to head to Duna (calculated with handy dandy online resources
  7. Launch Time: 5/27/14 Team Members: All Play-by-Play: Everything went as planned. Enter Kerbin orbit, created encounter with Minmus (prograde orbit), then circularized and brought it down to the surface. From there, took off in the same direction and returned home. Pretty cool stuff. (Oh man on the surface) (A little EVA fun. Jetpacks work particularly well on Minmus) (Our ships burn with the passion of a thousand Kerbonauts) (NOTE: not dead) Time of Flight: Not quite sure. We just sort of send Kerbals into space and hope they don't get too bored. Summary: Minmus
  8. Team Name: Big & Low LLP Available Funds: ~$120000 Vehicle Name: Mun Lander (although we're going to Minmus) Parts List (& Cost): Command Pod "Poodle" engine Sorta medium fuel tank Landing struts Parachute Decouplers Big fuel tank + Mainsail Engine 2 Solid fuel boosters Total cost: ~$110000 Design Goals: Off to Minmus (one stage to orbit, another for everything else) Launch Goals: Get to Minmus, without explosions or becoming in the cold, soulless void of space. Pilot Plan: Standard gravity turn into orbit, create node for encounter with Minmus to enter a prograde orbit,
  9. Launch Time: 5/21/14 Team Members: All Play-by-Play: Everything went as planned. Enter Kerbin orbit, created encounter with Mun (prograde orbit), then circularized and brought it down to the surface. From there, took off in the same direction and returned home. Also, did a nice EVA. Now this is a picture: Flag Swag: Time of Flight: ~ 10-ish hours? (sorry I don't remember) Summary: Got to the Mun, and perhaps more importantly, got back without severe casualties What we Learned: Planning is good (we used it this time), and the Mun is pretty cool. M

Team Name: Big & Low LLP Available Funds: ~$120000 Vehicle Name: Mun Lander Parts List (& Cost): Command Pod "Poodle" engine Sorta medium fuel tank Landing struts Parachute Decouplers Big fuel tank + Mainsail Engine 2 Solid fuel boosters Total cost: ~$110000 Design Goals: To the Mun! (with one (and a half) stages to get to orbit, and the second to get to, and then land and return from the Mun) Launch Goals: To the Mun, without any mishaps Pilot Plan: Standard gravity turn into orbit, create node for encounter with the Mun to enter a prograde orbit, then stabilize said o
  11. Why landing on Eve should be the ultimate prize: Getting to Eve isn't terribly tricky. In fact, of all the planets in the KSP universe, it is the easiest to get to, requiring only (when done right) 80 m/s of delta-v. However, landing on it (and returning) is the tricky part. Mainly the return. Landing on Eve is actually surprisingly easy (if, of course, you miss its many toxic oceans). Its atmosphere is thicker than Kerbin's, and hence parachutes work even better on it. But the higher gravity, combined with the thick atmosphere, means it is actually harder to get off of Eve than i
  12. The Kerbal Nomogram: What, exactly, is it? The kerbal nomogram is, simply, a nice little diagram designed to help you with your space travels. If you haven't checked it out yet, you can find it on the main aplusphysics KSP page, and I would recommend looking at it before reading this. Consisting of three little "rules", it provides a way to describe the delta-v equation: Substituting Mstart/Mend for a mass ratio instead, it allows you to take two know values (for example, engine specific impulse and the necessary delta-v), and calculate the value of the third one (in this
  13. Imagine you are in an orbit. Maybe its a pretty nice orbit, not to far from home, but not too close either. But for whatever reason, maybe because your satellite tv reception is poor or whatever, you decide it's time to move - to another orbit. Conventially, the way you would get their would be through a Hohmann transfer: an orbital operation designed to move you from one place to another. Here's a picture: In this example some lost soul is going from a small orbit to a large one. What exactly is going on? Initially, one end of your orbit must be brought up to the ne
  14. A discussion of Delta-V: What is Delta-v? Simply put, it is the change in velocity (delta velocity) from one point to another. There you go, that's all. But why is it important? In rocketry, delta-v is important because it allows you to measure the change in velocity you need to get into orbit, or get to the Mun or do whatever you like. For most space bound flights, delta-v provides a measure of how much "fuel" (essentially) you'll need to get somewhere else, and because the thrust from any rocket is constant is space, this is the main measurement tool used when calculating spac
  15. Launch Time: 5/20/14 Team Member: All Play-by-Play: Up until ~20km, everything was going well. However, when transitioning into our second stage, we hadn't built up enough velocity leaving us without enough time to utilize our lower-thrust second stage to push us into orbit before we were heading back down again. We tried to do a rocket-only landing in the water, but right near the bottom our velocity vector went a bit crazy and we would up crashing, killing all those involved. A real shame, but provided some good rocket-only practice. Time of Flight: ~ 5 minutes Summary: Got in
