PB666 posted a topic in Science & SpaceflightI thought this was already a done deal. http://www.businessinsider.com/nasa-mars-2020-mission-step-toward-first-mars-sample-retrieval-2017-12 Apparently the robot will have a biotype search and destroy mission. Well not destroy, just search, remove, put in a canister, put it on this big explody thing, send it on a mission in the cold deep of space, then burning into earths atmosphere, landing but . . . . .not destroy.
Just a quick mission to the Sun. Goal : Collect a sample of stardust and bring it back to Kerbin. How hard can it be ? (: Kerbol probe + Spacecraft : Probe: Name : Kerbol probe + Mass : 6895 kg Propulsion : Ion engine Power supply: 4x RTG Dv : around 11 km/s Communication : 1x High gain antena Shielding : 1000kg sunscreen Recovery equipment : none Sample return capsule : Mass : 700 kg Propulsion : none Power supply : 4x batteries Communication : 2x low gain ominidirectional antenas Shielding : Heatshield Recovery equipment : 1x main parachute. Mission Log : T - 0 Launch T + 20 seconds : Titan X rocket performs pitch and roll manuver to maintain optimal ascent trajectory. T + 1 minute and 30 seconds : Solid rocket boosters burnout and seperation : T + 2 minutes and 30 seconds : Payload fairing separation : T+ 4 minutes Main engine cutoff and stage one separation. T+ 5 minutes and 30 seconds : Second stage engine fires for 5 minutes to put the probe in a solar orbit. T+ 20 minutes Kerbol probe + seperates from a second stage. Spacecraft is now on a highly elliptic orbit around the sun with with AP far beyond Jool's orbit. T + 1 month Spacecraft enters hibernation state for next 3 years. T + 3 years and 256 days Kerbol probe + fires it's Ion engine for 2 hours and 20 minutes. This maneuver drops Pe to around 500 000 km. (Unfortunately, the communication system was not sufficient enough so I had to waste some fuel and perform this maneuver much earlier. ) T + 5 years and 120 days : After 5 years of flight, Kerbol probe + finally reaches it's destination. Due to the really high orbital speed, (>120 000 m/s), this part of the mission will last only for around 30 days. T+ 5 years and 135 days: The spacecraft pases it's peryapsis, 490 000 km above Sun surface. T+ 5 years and 217 days Spacecraft fires it's propulsion for 3 hours and 20 minutes in order to put spacecraft into return trajectory. T+ 7 years and 90 days Kerbin system entry. Probe performs slowdown burn to ensure that the return capsule will survive reentry. T+ 7 years and 91 days : Return capsule separates from the main probe. T+ 7 years 91 days and 2 hours. Return capsule reenters the atmosphere and lands in an ocean. The end
I recently got a complaint from Jeb, who stated that he was getting bored of flying to Minmus all the time. I guess even the vastness of deep space and the serenity of the void lose their charm after a while. Jeb explained to me that there were those of little faith who stated that Minmus was as far as Kerbal-kind was ever like to get, and that a body as heavy and distant as, say, Eve would be forever out of reach. "Never!", said Jeb. "I shall personally go there and what's more, I'll prove it! I'll even bring back some rocks from the surface, so that none of ye may doubt the piloting skills of Jebediah Kerman again!" Next morning Jeb woke up terribly hungover, but unfortunately Bob and Bill had captured his entire ill-begotten rant on video, making it impossible for him to back out now. Luckily Bob and Bill both, after a nice chit-chat with Jeb who didn't threaten them with any form of corporal punishment at all, volunteered to accompany Jeb on this heroic mission. The only problem with their fantastic plan is that the unbelieving Kerbals in the bar the night before were not entirely wrong - the Space Program right now doesn't have anything that's even close to capable of returning home from the surface of Eve. Good old Werner von Kermann soon fixed that though, resulting in the following monstrosity: - The Lander - - The Returner - - The Complete Ship - The mission is to bring Jeb to Eve's surface, let him collect a nice bunch of science while there, and then return him and the samples safely to Kerbin. Bob and Bill will remain in orbit (in a duo impersonation of Michael Collins) to keep the return vehicle running. The imgur album shows several screenshots of the ship in the VAB, captions provided. http://imgur.com/a/DLmc6 Next post will contain the Kerbin ascent!
