14. ## BCD Venture pt 1

Name: BCD Ventures Available Funds: 140,430 Vehicle Name: Aeris 3A Vehicle Part List and Cost: We used the Aeris 3A stock airplane for this flight however, as far as we know there's no way to see what parts were used in the stock craft. There appears to be only one Mk 1Fuselages in the entire craft and the discount was calculated accordingly. Total Cost: 13,330 Funds (including fuel discount) Design Goals: Fly to the northern ice cap and snap a screenshot of the UFO landing. Launch Goal: We are hoping to achieve the milestones: Picture of UFO on northern ice cap of Kerbin - \$50,000 Pilot Plan: This is a manned flight to the northern ice cap. Near surface flight and conservative fuel use will be observed during the trip.

We have carefully constructed the rocket to have enough stages to make it to the planet and back. Launch Goal: We are hoping to send Jeb to Duna and return safely! We expect to orbit Duna and make a safe return from the planet, too. We want to learn and demonstrate how to perform interplanetary travel and make sure Jeb has a ton of fun during the process. Pilot Plan: What will the pilot be doing during the different stages of the launch? Are there different activities / maneuvers to be completed at different altitudes or stages. The pilot will be reaching an orbit around Kerbin, as he has done many times before. Once orbit is achieved, a maneuver will be set up so that the ship will be pushed along the direction of the orbit of Kerbin, towards Duna. Aerobraking and parachutes will be used once in Duna’s atmosphere, and upon landing, Jeb will pack the chutes. A similar procedure will be performed to make it back to Kerbin safely!

Funding Edits: Due to funding oversights by myself there have been a few budget miscalculations along the way. Edit 1: On our mission to Minmus we achieved the milestone of First Kerbal EVA when Fuelanov planted our country's glorious flag adding \$30,000 to the budget. Edit 2: On our mission to the North Pole we recovered our jet giving us \$7,075 back to the budget as those parts could be reused. All future posts will have these edits accounted for in the budget.

That is quite the find! Very cool... well done!
20. ## Orbital Recap

Very nice! Congrats on the achievement payouts!
21. ## Can We Please Get to Orbit?

What's Bob going to do after he achieves orbit to get home safely?
22. ## Orbital Recap

Launch Time: 6:44.91 Team Members Present: All present and partaking Play-by-Play: At the beginning Bill Kerman boarded the rocket Launch Meat and and was strapped in. Then once the weather cleared, the boosters ignited along side the rockets main engine and Bill oriented the rocket towards the east. The boosters were dropped when they ran out of fuel. As the rocket traveled, it neared an apopsis of 80,000 km Bill Kerman turned off the throttle and began to coast towards the altitude of 80,000. Upon reaching the apopsis, Bill turned the engine back on full throttle to burn the last of the fuel in the first stage. Then the first stage detached and fell back towards Kerbin, and Bill fired up the second stage to reach orbit. Photographs: Each launch should be accompanied by a minimum of two photographs from the mission. Screenshots may be made by pressing the F1 key at any time during the mission. If an award is achieved, make sure you take a screenshot as proof of the accomplishment. Time-of-Flight: 9:22 Summary: In this launch team F'N Sandwich and pilot Bill Kerman achieved a stable orbit. After many failed tests, this goal was reached as our greatest milestone so far. Going forwards, we have learned that a greater heat shield will be required as the one used during this launch was damaged. Opportunities / Learnings: We learned that practice makes perfect and how to maneuver the rocket in the ways and orientation that we want. It gives us the confidence to move towards a moon landing or satellite launch. Strategies / Project Timeline: This launch will set in motion missions of greater complexity. We aim to either put a satellite in orbit around Kerbin or put a Kerbin on the moon. Milestone Awards Presented: We achieved a stable orbit and a stable manned orbit, and a launch to 50 KM for \$20,000 \$25,000 and \$10,000 respectively. Available Funds: We have \$68,508 remaining prior to the possible \$60,000 in rewards for our achievements.

Launch Report and Debrief Launch Time: 10:41 Team Members Present: Kyle Upson, Alex Wansha, Julia Vanill Play-by-Play: Heading straight up maneuvering West to get into orbit around Kerbin decoupled 3:53 using solar panels on rover to help power ship maneuvering into Mun's orbit 5:42 decoupled 7:04 Mun apoapsis 35km maneuvering into orbit around Mun 1d, 00:46:11 using monopropellant to eliminate horizontal velocity landing on Mun without landing gear landed 1d, 1:32:03 no wheels on rover? Photographs: Time of Flight: 1d, 1:33:17 Summary: The launch to the Mun with a rover proved to be mostly a success, except for the fact that the wheels popped somewhere along the way. However, we were still able to control the rover on the Mun without the wheels because we had monopropellant. Opportunities / Learning: We learned how to build a rover and successfully land on the Mun. Strategies / Project Timeline: Next we plan to make a jet to fly to the Northern Ice Cap and take a picture with the UFO. Milestones: Working Rover on Mun - \$500,000 Available Funds: \$468,537 - \$42,796 + \$500,000 = \$925,741!

We need a lot of liquid fuel and need our design to effectively lay our payload down on the surface without damaging it. We also need a rover which can be controlled with wheels as well as with monopropellant if something bad happens. Launch Goal: We are hoping to learn how to effectively put a rover on the Mun. Milestone: Working Mun Rover functioning on Mun - \$500,000 Pilot Plan: Launch to 20 km above Kerbin and begin angling west Burn until our apoapsis is 90 km above Kerbin and drift until this point Make our orbit circular at this point Plan/execute encounter with the Mun Center the Mun at our periapsis and slow until 20 km above the moon Stop horizontal motion, land, and slowly eject rover onto the surface Our proud Rocketslovian rover shall do doughnuts around the craters on the Mun... FOR SCIENCE!!!!

28. ## Can We Please Get to Orbit?

Pre-Launch Design Release Team Name: F'N Sandwich Available Funds: \$80,183 Vehicle Name: Launch Meat Vehicle Parts List and Cost: MK-16 parachute- \$422 MK-1 Command Pod- \$600 7 FLT-200 Fuel Tanks- \$1925 2 TR-18A Stack Decoupler- \$800 2 TT-38R Radial Decoupler- \$1200 FLT-400 Fuel tank- \$500 2 Rt-10 hammer solid fuel boosters- \$800 LVT-45 Swivel liquid fuel engine- \$2400 4 AV-R8 winglet- \$2560 2 aerodynamic nose cones- \$480 Total Cost: \$11,675 Design Goals: This rocket was designed to send a Kerbal into orbit around Kerbin. Two booster engines helped to gain speed and our swivel engine helped us maneuver the rocket to the east to reach orbit. Launch Goal: We are hoping to put a Kerbal into a stable orbit around the planet Kerbin. If we succeed we will earn the achievements of an successful manned launch to 50 km, a stable orbit and a stable manned orbit. Is successful, our group will earn \$60,000 from these milestones. Pilot Plan: First Bob Kerman will ignite the booster engines and the swivel engince to gain speed. He will then angle the rocket towards the east to position the rocket in the correct orientation to leave Kerbin. He will then wait apoapsis to reach 80 km and then shut off the engines. Upon nearing an altitude of 80 km, Bob will re ignite the engines to push the rocket into orbit. Illustrations:
