Great success! Although, one of the engines did shut down. At least now we know for sure that the engine-out capability works From SpaceX: “Falcon 9 detected an anomaly on one of the nine engines and shut it down. As designed, the flight computer then recomputed a new ascent profile in realtime to reach the target orbit, which is why the burn times were a bit longer. Like Saturn V, which experienced engine loss on two flights, the Falcon 9 is designed to handle an engine flameout and still complete its mission. I believe F9 is the only rocket flying today that, like a modern airliner, is capable of completing a flight successfully even after losing an engine. There was no effect on Dragon or the Space Station resupply mission.â€Â

Here's a mission timeline for SpaceX CRS-1 for those of you who are interested in following the mission: Day 1: LAUNCH COUNTDOWN Hour/Min/Sec Events - 7:30:30 Vehicles are powered on - 3:50:00 Commence loading liquid oxygen (LOX) - 3:40:00 Commence loading RP-1 (rocket grade kerosene) - 3:15:00 LOX and RP-1 loading complete - 0:10:00 Falcon 9 and Dragon terminal count autosequence started - 0:02:30 SpaceX Launch Director verifies go for launch - 0:02:00 Range Control Officer (USAF) verifies range is go for launch - 0:01:00 Command flight computer to begin final prelaunch checks. Turn on pad deck and Niagara water - 0:00:40 Pressurize propellant tanks - 0:00:03 Engine controller commands engine ignition sequence to start 0:00:00 Falcon 9 launch LAUNCH Hour/Min/Sec Events 0:01:25 Max Q (moment of peak mechanical stress on the rocket) 0:03:00 1st stage engine shutdown/main engine cutoff (MECO) 0:03:05 1st and 2nd stages separate 0:03:12 2nd stage engine starts 0:03:52 Dragon nose cone jettisoned 0:09:11 2nd stage engine cutoff (SECO) 0:09:46 Dragon separates from 2nd stage DRAGON ON-ORBIT OPERATIONS IN THE FAR FIELD Hour/Min/Sec Events 0:11:45 Start sequence to deploy solar arrays 2:26:49 Start GNC (guidance and navigation control) bay door deploymentâ€â€this door holds sensors necessary for rendezvous Day 2: DRAGON PHASING – DRAGON BEGINS APPROACH TO SPACE STATION • Coelliptic burn places Dragon in a circular orbit Day 3: HEIGHT ADJUST MANEUVERS TO R-BAR AND CAPTURE (R-Bar - Radial Bar - is an imaginary line connecting station to the center of the Earth) • Height adjust burns start adjusting altitude higher toward station • COTS Ultra-high Frequency Communication Unit (CUCU) and on-board UHF communication system between Dragon and ISS is configured • Height adjust burn: Dragon begins burns that bring it within 2.5 km of station (go/no-go) • Dragon receives and sends information from/to the CUCU unit on station • Height adjust burn brings Dragon 1.2 km from station (go/no-go) • Height adjust burn carries Dragon into the station’s approach ellipsoid (go/no-go) • Dragon holds at 250 meters (go/no-go) for confirmation of proximity sensors targeting acquisition • Dragon begins R-Bar Approach • Dragon holds at 30 meters (go/no-go) • Dragon holds at capture point, 10 meters below the station (go/no-go) • Crew captures Dragon using the station’s robotic arm (SSRMS) • Dragon is attached to the station Day 4: HATCH OPENING • Hatch is opened RETURN DAY -1 • Hatch is closed • Dragon vestibule de-mate and depressurization RETURN • Station’s robotic arm uninstalls Dragon • Robotic arm releases Dragon • Crew commands the departure • Dragon starts departure burns • Dragon closes the guidance, navigation, and control bay door • Deorbit burn • Trunk jettisoned • Drogue chutes deployed • Main chutes deployed • Dragon lands in water and is recovered

More gas giants (with rings!), more moons and some dwarf planets and asteroids.

Väl mött landsmän! Prata KSP och spela samtidigt låter som en kul idé. Jag skickar dig ett PM, Hofugir.

Thought I'd share this with you all: https://planetary.s3.amazonaws.com/assets/images/charts-diagrams/20120928_solar-system-missions2012-10.png Source: http://www.planetary.org/blogs/emily-lakdawalla/2012/09281400-whats-up-october-2012.html

Hello! I tried the demo a month ago and got hooked. Bought the game in time for the 0.17 update and I'm loving every minute of it. Can't wait to see what the future brings for KSP
-
I shan't (see what I did there) name call, I'm sorry. Alright, fair enough.
-
Hey CardBoardBoxProcessor, I like this mod a whole lot, I'm just giving you my opinion and offering some constructive criticism. You don't have to listen to me, but you don't have to be boorish either. If real-size Angara 2.9/3m rockets and engines are coming I will patiently wait. Thanks for a great mod!
-
I can understand wanting to have it fit stock parts, but now there's a disconnect. The KVTK and the VA are real life sized, but the Angara is not. As far as I can make out it's 2.9m in diameter. There are also no payload fairings, and this combined with the small rocket leads to some game-breaking wobble.
-
CRS SpX-1 will be fun to follow, but what I'm looking forward to the most is the first Orion test flight in early 2014. That, and the next big robotic mission to the outer solar system (Jupiter icy moons explorer) are things I look forward to.
-
Different times. Doesn't mean it can't happen again; same human beings and all, but I don't see another Operation Meetinghouse happening ever again (25% of Tokyo destroyed, 100,00 people killed in one bombing raid on March 10, 1945), or at least not in my lifetime.

Fantastic stuff! Can't wait to try this when I get home
-
Hello! I achieved my first successful Mun landing today! Unfortunately for Jeb the lander has precisely 0 fuel left (it was a scary landing)
-
Do any of you know how to reduce or remove the wobble from interstage-to-payload-fairing and fuel-to-engine connections? Struts aren't getting the job done.
-
Hello! First of all, I really like this mod! I love the look of the engines and the payload fairings. However, I'm having some problems with the interstage decouplers. How do you get them to fit your rocket properly? No matter what I try I get wobble and struts are impossible to use, because they only connect with the interstage on the inside, near the bottom, and it still doesn't help. Is there a way to do it properly? Is it an issue with these parts at this time? Someone please help me
