  1. expensive like falcon9R? "its only expensive because your using its wrong" Chris Kraft. We are all still thinking about today and tomorrow and not in 5-10-20yrs time. Mars base, crew member has heart attack, survives but will eventually need a pacemaker to be fitted by the crew surgeon...earth develops a intrinsically safe, radiation proof, magnetically inert pacemaker at the cost of $50billion.... are you going to put it on the cargo craft where if it goes pop 6 seconds from the pad you can recover it OR are you going to take your chances risking the crew members life on mars AND...ALOT of tax payers money? I know what your saying about cargo though... but science experiments cost mega money. some have been worked on for years with large teams only for the equipment to be destroyed. Cygnus itself...$50mil or more? Dragon2 can be reused and ensure cargo safety.. just as dreamchaser could/will. struggling to see why a Dragon hasn't been reused yet... I'm sure its capable
  2. This is why I find it unthinkable for dreamchaser to be defunded (canned) by NASA. I know its ONLY cargo but lets face it, the cargo and the craft would have survived to be used another day...same with dragon2... Dreamchacer was the only one NOT to use highly toxic mono propellants reducing risk to crews on the ground/public/wildlife/environment I know they are human taxis but why not used them for cargo to limit losses.. the rockets the cheap bit...its the part on top that costs the $$$. launch escape for cargo? I'm a big lover of ATV but even it doesn't have a place in this world right now. Dragon2 and Dreamchaser....I mean effectively what were saying with cargo rockets is, "nah if it blows up its ok".... why not protect all this expensive equipment like we do humans? Solid propellant upper stage??? We all in 12th century china? Tubes of black powder were not in fashion back in the 60's when we landed on the moon, they sure as heck arent high-tech now... I propose this.....the cost of this 'mishap' alone has cost more than the development of a liquid upper stage for Antares would have been. Anyway, I'm an engineer and part-time firefighter with a reasonable knowledge of turbo pumps/jets/rockets, my guess is the turbine blades (first cast in maybe 1972ish) broke loose and destroyed the pump shutting down the engine. lost thrust, hit the deck where the tanks ruptured and hey presto you have a fuel air bomb sat on the pad. There is a part with some serious rotational energy that makes a run for freedom in the top right hand side of the footage which can be assumed is a turbine shaft, maybe a small tumbling solid ejection motor, I don't know. not sure this vehicle uses them...anyway The plume turns more orange and less violent in nature right before the engine dies and the rocket loosed altitude (akin to adjusting the vent on a Bunsen burner)..It was running fuel rich!!. RP1??? So lack of liquid oxygen Makes sense if its the oxidiser pump.. cast hot. ground cold, tested cold, sat for 30yrs, (30 Russian summers and harsh winters) change of climate, machined again, tested cold, then ambient for another few months and then put under chill down and duty cycles for hotfire test...etc..... so many times! and with the scrub yesterday.... its PURE METAL FATIGUE. there are only so many times a part can be frozen down to −297.33 °F, −182.96 before is just cracks. As much as that sailboat scrubbed the launch first time out, it could possibly be the reason for the 'mishap' that destroyed Antares...one chill down to many!
  3. I think its fairly obvious what its doing up there don't you? I mean there are plenty of spy satellites so its obviously not looking down. Its taking hi-res, close up, shots of other people (countries) "stuff". Looking at there architecture, capabilities etc. The best way to intercept transition of data...? Be right next to the satellite that's relaying and retrieving it. Explains the secrecy, relatively small size, need for a high Delta V for changing altitude/orbit plane, AND the need for it to be reusable because eventually it would need to come down to refuel. It couldn't be just left for someone to discover. Back in the 50's the US experimented with skipping off the earths upper atmosphere to gain altitude and change course with the Lynx space plane I believe (or that was the plan I think, not 100%) Putting a heat shield on a disposable satellite to do be able to that task would no doubt leave evidence when it re-entered the atmosphere... so make it fully reusable.. ala the X37 I mean its way to small to meaningfully refuel an existing satellite and why would you? The USAF have just block brought 47 (?) cores to lift new, more capable, satellites into orbit.... Why use a whole Atlas 5 to just top up an old one? It makes more sense to send up a new one while using an X37 to spy in on other countries spy satellites. Know what they know about you, know what they are doing with land, sea and air assets...effectively you know what they are GOING to do before you've even seen it take place with optical spy satellites. DATA is what makes countries dangerous nowadays, not war ships and nukes. If you were responcible for homeland security what would make you feel safer at night.....an optical spy platform overlooking a hostile country OR a reusable space plane that can sit by the side of a geostationary mobile communication satellite for 2 years at a time listening in on 2 million phone calls and internet streams 24/7 for NSA/GCHQ to monitor....
  4. i have a intel i7-2600 8 core cpu running @ 3.4ghz. along with a 3gb Nvidia GeForce GT 545 graphics card connected to 12gb DDR3 ram and i still get lag when moving from the VAB to the launch pad
  5. shaddowing a previous thread...http://www.kickstarter.com/projects/902505202/castle-story?ref=category hit there goal in less than 5 hrs!!! [Deadshot462 (mod) - Topic title updated to prevent multiple thread creations]
  6. Dude...PLEASE read the Comments further back in the thread. This has been problem since .15 Cepheus (the current mod "controler') is trying his hardest to find time to fix this mod. But like all talented people, he's in demand at the min. You should use the supplied craft file and it shouldnt be a problem. NOTE TO CEPHEUS... Not sure if you saw the thread but jordancox has officially ended his SLS/ares pack and has made a strict point of making sure people don't use his stuff. Hopefully this doesn't effect the CSS seeing as the SRB's are of his design (although modified to a different aspect ratio). Anyway hope you keeping well fella, and no rush on the update. Anything I can help you with let me know. P.s gone and got myself a 6core i7 pc with 16gb of ram and 6gb of dedicated graphics ram so if you want any help running the pack at full graphical specs I should now be able to do so. Cheers
  7. I say it lands...but something goes wrong. 72pyros on the thing for peres sake with only dual redundancy on a craft that has ONE chance. Anything fails and it can\'t solve the problem before the fuel runs out and the crane will either collide with the rover OR take the rover for a ride when it shoots off. I dunno, maybe a sticky head shield. Only 1 strand of the supersonic chute snaps/twists ect. It\'s a very 'cool' design but not a simple one. Complex things go wrong often.. I bet a £200 gift voucher to Ann summers for the wife it\'s apart sucsessful... The amount I\'ve been working/playing kerbal lately, she appreciate it, if she wins Just out of 'curiosity' (every pun intended) when is the lander planned to enter mars atmosphere in GMT? So UK time? And will NASA tv be covering it?
  8. Got it in the end. Now on the last mission. You can tell they have built the game with expansion in mind with boosters and the lander ect. Awaiting shuttle and luna missions in the next update. Could be a pretty epic game of kerbal proportions
  9. Sorry for the necro but surely there has never been a better time to revive this mod CCBP? Scales are practically perfect now, addons could intergrate mechjeb, crew, solar panels, launch escape and I know it\'s a huge ask but may as well get it ready for docking. Either way, sorry for the necro again but this mod was the first I though about as soon as I saw the new bigger scale parts
  10. Anyone figured out how to get past the mission with the Hubble? Can\'t do it to save my life!!
  11. I saw, I brought, I loved! Brilliant little game and addictive as hell...thanks for sharing
  12. loving the pokeball texture! lol. great work though. Any chance of a test release of anything some time soon? would love to get involved in ballancing parts for you
  13. To be honest I\'m not quite sure. I run an acer aspire all in one touch screen and the graphics card is intergrated into the motherboard so isn\'t upgradable, nor is it a standard bit of kit that can be plugged into any other pc. Spend 99% of my time on my iPad so will check it out in the morning (23:06 here and I\'m up at 6:00am tomorrow for work so..) Any known fixes? Will be removing the back cover and cleaning my pc this week so that may help if it\'s an overheating problem. May also look into an unrated fan as the screen, speakers and drives all so tightly packaged next to the chipsets acts as a huge heat soak which the fan struggles to shift.
  14. ANYTHING running in unity is doing this to me. Including Kerbal. I can run more intense program\'s without fault. But codemasters F1 online, family guy online (both unity web based browser games) and kerbal (unity built) just crash..and not even with any warning or graphical glitches. It just shuts my pc down.
  15. I remember her as bit of an activist and hard nosed SOB. She were set on being the first TFNG woman in space and didnt care who she pi$$ed off to get it. Personaly I think she was the perfect woman to be the first american female into space although maybe not the most deserving. Either way she brought Human space travel to the fore front of people\'s minds and,among other things, battered safety back into the minds of people at NASA after the challanger disaster. Sad day indeed. RIP Dr Sally Ride.
