  1. STATIONS STATIONS STATIONS!!!!! Space Stations are going to be a focus of the next couple missions! I'll be working on Shuttle Skylab Missions, Shuttle Mir Missions and a Shuttle Salyut mission in the near future. I'd like to thank you for responding to the poll! It's good insight that people do in fact like the more information based missions They are my preferred mission type to make as I love reading about the details myself but I there is a significant amount of votes for more imaged based works is important. The way I'm probably going to proceed is do a Shuttle-Skylab mission which was only proposed and not actually flown in a more image based way, and then conduct a Shuttle-Mir mission which did happen in an information based way. Afterwards depending on how I feel I'll probably bias to one way or the other. I'll probably stick to more information based both due to poll results and my preference but who knows! I am willing to accept any feedback you'd like to offer in fact if you do have any ideas or suggestions please do speak up! Anyways life permitting, I hope to have more missions coming soon! Until then, so long!
  2. Revitalization of an Oasis Among The Stars: Featuring Space Shuttle Challenger Can't wait to fully conduct the Shuttle Skylab missions with these wonderful parts! The question is, do the Shuttles take the classic shuttle stack or a Saturn-Shuttle to orbit?
  3. Modular Skylab I think its beautifully cursed! Can't wait to send the Shuttles to Skylab with that bad boy! Those parts are beautiful! Fantastic work as always!
  4. Seldom do I find myself as excited for a mod than I am for this! I played with Ad Astra prior to moving to KSRSS a little over a year ago and I always missed the legendary visuals I had left behind. I cannot wait to play with this!
  5. A wonderful mod called Waterfall and Rocket Motor Menagerie! The SSMEs from RMM are 25% too big so I scaled the rocket plumes down accordingly. Using Tweak Scale it goes from 1.25 to .938 and the SSME waterfall config goes from 1.33 to 1. I also clip two of the scaled SSMEs where one would reside to correct for the thrust lost. Hope this helps!
  6. Go for it! Can't wait to see it! As for the other questions, I am certain Lemon's tank is a custom creation made of Restock bits but as to wring wear on the Shuttle that something I am not aware of . P.S. I've been loving your thread!
  7. You’ve got it right. It was quite a wacky process! As to convert over previous saves, they load fine but the .25x RSS Earth is slightly bigger then 2.5x Kerbin KSRSS, Atmosphere size follows that same trend. So currently all my LEO craft are screwed in old saves but with some tweaks in the sigma rescale configs I could probably do it. I’m also fine with starting a new save as mine was rather cluttered in LEO . I’m still having a little trouble with the local terrain near The Cape but it’s a small price to pay for my Venus and Titan being intact !
  8. The X-38 Crew Return Vehicle - An ISS Blueprints Special The X-38 CRV was a component planned to be provided by the United States to act as an escape pod in the event of an emergency on the Station. I've documented its history and its planned mission and demise in Shuttle Adventures! You can find parts 1 and 2 below. I am quite proud of these missions and I believe the CRVs significance to the ISS warrants them being linked here! Check them out if you’d like and I'll leave you with a nice picture of the ISS in the CRV timeline prior to the deliver of the CRV:
  9. The X-38 Crew Return Vehicle: Part 2 - STS-136 - April 2007 In the beginnings of the program, the X-38 was scheduled to have an orbital test flight in 2001 but after several delays the craft would launch aboard Space Shuttle Discovery to be integrated with the International Space Station. Classified as an Assembly Mission, the CRVs test was one of the final Scheduled missions for the stations assembly, falling behind only the Centrifuge Accommodations Module. Discovery and the crew stood by at Pad-39A awaiting the window to launch for the Orbital Outpost. Prepare to be spammed with images. Information on this mission is quite sparse and that will be explained later. So instead of giving detailed information about mission timeline, I'll have pictures and intermittent procedure information. Lemon_Cup's plumes are flexing their muscles here! Absolutely Fantastic! After the 8 minute ascent and orbital insertion burn, Discovery prepares to expose the Crew Return Vehicle to vistas of the Cosmos. V-201 sports an addition that the previous vehicles didn't, The Deorbital Propulsion Module, meant to deorbit the CRV. Space Shuttle Discovery isn't equipped the the Canadarm as the CRV takes up space where the Canadarm would normally reside. In addition the Crew will continue procedures to Rendezvous with the International Space Station. Over the coast of California, Approximately 2 days after launch, Discovery, The CRV, and the International Space Station drift together and dock, marking a major milestone of STS-136's mission. Crew aboard the Station monitor the docking through the the Cupola and then begin to prepare to berth the CRV to its designated Adapter. After being berthed, the crew entered via Tranquilities Starboard hatch to examine the spacecraft and begin its long duration test. First spending 3 months docked to the ISS then autonomously undocking deorbiting and landing. For now ,the joint ISS and STS-136 crew would conduct experiments and maintain the ISS before Discovery undocked. After backing off from the Station, Discovery prepared to deorbit and land at Edwards Airforce Base. After landing at Runway 22 at Edwards, Discovery flew back on the SCA, leaving the place where the CRV took its first flights, after delivering the CRV to its first stay in space. Back at the Station, the CRV is awaiting its first departure and deorbit. The CRV would back off from its docking port, then weave in between the large S1 Radiator array, then slowly drifts from the Station. then the CRV would coast to the point in which It would deorbit, using the DPS and then jettisoning it, reorienting and preparing for reentry and landing at Edwards. After being recovered, the CRV would be returned and eventually be crew rated and launched again to support the ISS. I am not sure whether it would have flown on an SCA but I think it was too cool to pass up on! Additional Use Cases and Fate of the Crew Return Vehicle The Crew Return Vehicle had no reason to be an STS exclusive. With additional modifications including a launch escape system and a new service module, the CRV was studied as being used with the Ariane V: and Delta IV as a crew transport. But unfortunately this would never come to fruition. It is important to know that the Crew Return Vehicle was placed under the budget of the International Space Station and as the budget grew out of proportion, Congress deemed that things needed to be cut to save money. Along side the Habitation and Centrifuge Accommodations Modules, the Crew Return Vehicle was cut from the project. To add insult to injury, V-201, the orbital prototype was 90% complete at the time of cancellation. Finally, less than a year after its cancellation, Space Shuttle Columbia would tragically be destroyed after being struck by Foam from the External Tank and burning up on reentry, resulting in STS-136 being cancelled along with most other missions on the launch manifest prior to the disaster. The Space Shuttle Program would eventually come to a close at STS-135, NASA just clawing that back from the jaws of Congress with them initially only funding through STS-134, making STS-136 sound a bit off. An echo of what could have been. Something that puzzles me personally is that Scaled Composites, the Company that manufactured the Prototypes didn't throw their hat in the ring for the Commercial Cargo and Commercial Crew contracts. The closest thing we have to the X-38 now is the Dream Chaser, the modified design of the HL-20 that lost to the X-38 prior. It may have lost the battle but it will win the war once it docks to the ISS in the coming years. I loved making this mission! It was a long time in the making and the part lag was awful (ISS + Shuttle + CRV was approximately 600 parts) but it sure was worth it. I hope you've enjoyed it as much as I did making it! More missions coming soon and I'll leave you with a picture of two Shuttles on SCAs right next to each other! So long!
  10. The X-38 Crewed Return Vehicle: Part 1 - The Dryden Tests - 1997 - 2001 The Genesis of Space Station Freedom along with immense excitement and inspiration came concerns, chiefly, return of the crew. Initially, the idea would be to leave the crew on orbit with no vehicle docked to the station. In the event of an issue, a Space Shuttle would be launched to return the crew. In the wake of the Challenger Disaster, it was understood that this was not a solution. Space Station Freedom needed a dedicated Escape Pod. Now Space Station Alpha and eventually the International Space Station, the problem had not changed. Several designs has been considered with two major differentiations, Capsule or Plane. Capsules had several ideas behind them, first being based around the Viking Probe Heatshields followed by Apollo derived capsules, and lastly the Russian Soyuz space craft. Then in the Space Plane division the HL-20 was considered (Which would evolve into Dream Chaser) and the X-38. When considering the possibility of injury, the space planes would apply less load on passengers than a capsule, leading to the X-38 selection. The X-38s design can be traced back to 2 major projects in the 1960s, the American X-24 and the Soviet Spiral space plane. All being Lifting body designs the X-38 would follow in their footsteps. The X-38 was an exception in many ways to the X-plane program as it included the European Space Agency and the German Space Agency. In addition the X-38 was originally designated the X-35 but redesignated to avoid confusion with the Lockheed Martin X-35 the precursor to the F-35 Lightning II. The X-38 was designed to fit into he Space Shuttle Payload bay and return to the Earth as a glider, eventually deploying the worlds largest parafoil prior to touchdown. The X-38 underwent several tests amounting to the first drop tests in 1999. Bound to a B-52 the X-38's V-131 V-132 and V-131-R would be deployed at 45,000 feet and near transonic speeds to then glide to a runway at NASA Dryden at Edwards Airforce Base. Deploying the parafoil the X-38 would be guided autonomously with a backup ground based pilot ready to intervene. With successful flights under the programs belt and the design being refined NASA began the exciting prospect of X-38 Vehicle-201 the Orbital Prototype. Part 2: STS-136 Coming Tomorrow!
  11. A Trip Home On Demand! The Cancelled Crew Return Vehicle & STS-136 Coming Soon...
  12. Now We're Cooking With PBAN! Many Thanks to Lemon_Cup for their fantastic work with the SRB Waterfall Configs! Boost phase has never looked so great!
  13. Launch Complex 39B - A Beautiful Legacy and Future The LDC parts were great for the Ares 1X Second Stage! TUFX's affect on the visuals are profound for screenshots! P.S. Happy Roll Out!
  14. As a Delta IV lover I am absolutely ecstatic that LC 37 gets the treatment it deserves! Can’t wait to play with the update!
  15. Looks absolutely amazing! I'm happy you've made a black variant for us EFT-1 lovers! Delta IV + Orion = Forever . Cant wait to give it a spin! Happy Rollout Day!
  16. Engine Swap! - An Update of My Activities! Hello! I wish I could say I've been making progress on upcoming missions but I regret to say I haven't . But I can explain myself. First, some exposition. I had conducted all of my missions in KSRSS at 2.5x Kerbal Scale and used KSRSSVE for most of that time. Well, while snooping on the forums, I discovered a mod called KVE, which modifies the textures of Earths Surface and Clouds and makes them look absolutely stunning. When I tested it I was hooked. But all good things come at a cost. For some inexplicable reason, to not only me but the mod author as well, Venus and Titans atmospheres were altered. Some examples are included after their respective correct counterparts. Venus is my favorite non Earth planet and Titan is my second favorite moon (after good ol Luna) and I was not about to give them up. I was also not going to give up that fantastic terrain. After snooping in the KVE thread and noting that the Mod author had not solved the issue and had not been on the forums for a while I elected to try and fix it myself. Nothing seemed to work including me deleting Venus and Titan, copying their assets into a separate mod I structured in such a way to isolate them from KSRSS and KVE. Granted I'm no mod expert so I probably did something wrong or stupid . So after a bit of time defeated I came up with one final plan. Swap out KSRSS with RSS! (While finishing up I thought of the RS25 swap on SLS so that's the title explained!) Of course downscaled to 2.5x Kerbal Scale. After installing RSS, having issues with KK not playing nicely and repositioning the Katniss Cape ground, I am fairly confident I have won the battle between me and modding! It isnt exactly the same and I am working to continually refine it but I hope that this will be the last modding complication for a while. Here are some results! I think it was worth the time! Some very exciting things are about to happen! SLS roll out, wet dress, and hopefully a subsequent launch! I plan on covering the SLS launch vehicle in the thread here but I am considering making a dedicated thread for the Artemis Missions! Covering launches such as CAPSTONE, Gateway and subsequent assembly and resupply missions, obviously the landings, and other things! Tell me what you think of this and where I should start? All they way back to OFT-1 and Launch abort tests? Start with CAPSTONE? I am all ears. Lastly, the missions I currently have planned in no particular order, Solid Rocket Booster Segment Derived SDLVs, X-38 and STS-136, Shuttle Salyut Program, The First Hubble Servicing Mission STS-61, and last but certainly not least, STS-51A. Sorry for the delay in reports, more missions coming soon!
  17. Exceptionally excited for this! Realistic screenshots will continue to be pushed further! I believe that the Japanese H-II mod, Gemstone LV and Knes would be mods worthy of your treatment. Can't wait to watch this mod develop further!
  18. Space Shuttle Advanced Boosters - A Series of Investigated Upgrades to STS The Space Shuttle's Solid Rocket Boosters accounted for 85% of the lift off thrust, and 69% of the lift off mass on any given mission. The SSSRMs were the largest solid rocket boosters ever flown and helped push the Space Shuttle to contribute all of its missions, except for their only failure during STS-51-L more commonly known as the Challenger disaster. Before and after Challenger, studies were conducted on the replacement or modification of the boosters to provide more payload to orbit or cheaper flight costs. Detailed, are the Recoverable Liquid Booster and Filament Wound Booster Casings. Eventually I will cover the modification of existing booster casings such as the 5 segment booster, SRB-X, and other varieties. Recoverable Liquid Boosters When the Shuttle had just left the ground on the Approach and Landing Tests, NASA already had plans to replace them with the Space Shuttle Recoverable Liquid Boosters. These unlike the solid counterparts could be shut down midflight in the event of a failure providing a Shuttle better abort modes to save the crew on ascent. The Liquid Boosters would be powered by a special variant of an RS-25, a model with an expansion ratio of 35 instead of the standard 69. This is due to the fact that the boosters would be only flying in the dense atmosphere thus the over expanded nature of the Standard SSME was not necessary. After the Boost Phase and Booster Jettison, they would fly much the same path as the standard solids. With an eventual destination in the ocean the engines would be covered with an inflating hemisphere to shield the engines from the corrosive sea water. It was hoped that with he new liquid boosters, flight safety and cost per kilogram of payload could be improved allowing for more flights for the Shuttle program, permitting for novel new payloads. Filament Wound Casings The USAF was a major component of the design of the Space Shuttle contributing heavily to the shape of the orbiter and the addition of a second launch site at Vandenberg Air Force Base. But the Air Force could not beat the physics involved with there plans. Launching satellites to polar orbits necessitates you loosing all horizontal velocity east to west, including that provided by Earth. Since you are spending precious fuel to cancel out Earths rotation, you lose payload mass to compensate. So the only way to gain back more payload it to lower the dry mass of your rocket. The Space Shuttle Solids, were made from steel casings allowing for some margin to be made by remaking them with Carbon Composites, allowing for heavier [REDACTED] to be deployed into high inclination orbits. At the locations of the mounting points to the ET, steel is kept for addition structural support, in addition to the normal Avionics, Aft Skirt Section, and Parachute cone. FOIA request of such a mission provided by the USAF - Totally 10000% real This was a fun one to make! Special thanks to @lemon cup for their awesome work on the Solid Rocket Plumes! I plan to show them off more with the segmented boosters installment. Life's been rough schedule wise so I hope to be more frequent here in the future, life permitting . More missions coming soon ! I had been cowering the web for the mod for a while but then some KSP YouTube video had it in the description! You can find it here!
  19. Hello, I have been playing around with a mod called KVE for another mod, KSRSS but keep experiencing a problem with atmospheres of Venus and Titan. The mod author has seen this problem and hasn't found a solution so that why I've come here. Here's the issue with KSRSS and KVE: And here's what they normally look like with just KSRSS: What's odd is that Venus and Titan aren't meant to be affected by KVE but still are and that Mars is left unaffected. Here is the log with KVE and KSRSS and the log with just KSRSS. I've done a little experimenting and I've found that when the modified KVE Clouds.cfg is installed, it bricks the atmosphere of Venus and Titan but the standards KSRSS Clouds.cfg leaves Venus and Titan fine but bricks earth. I presume this is due to the fact that KVE introduces new textures for Earths atmosphere and terrain and cant be handled by the original KSRSS Cloud.cfg but why it breaks Venus and Titan is a mystery to me. I don't really understand much of anything about module manager . Hopefully this is all the information you need and if you need anything else I'll try to get it to you as fast as possible. Thanks!
  20. Well I can give you instructions on how I did it but whether its properly implemented is up to the eye of the beholder! Without further adieu: Spawn in a craft and then open the cheat menu or hyper edit and set yourself to Edwards Airforce Base's Location 34.9240° N and 117.8912° W. Open your Kerbal Konstructs Menu (CTRL+K) and navigate to find "Edwards Land" and spawn it in. Set the Scale to 15 (I decided this by eyeballing the runway scale with the a SOCK Shuttle's Wingspan) and then find a nice place to put it down and then put it down You now have your very own Edwards Airforce Base! You could go through and line up structure with the correct orientation so the runways actually line up with their correct headings but I haven't done that as if yet. I'm not sure if they're already lined up or not... You can now enjoy landing your Shuttles on the sweet lake beds of California. And for viewing pleasure, some pictures of an STS-114 landing I did before I realized they landed at night . Hopefully this helps you out!
  21. Here it is! I manually placed it and rescaled it to a position I thought was adequate for the KSRSS terrain. The texture up close is rather pixely but that's to be expected with stuff like this . Enjoy!
  22. STS-114 - The Return To Flight - July 26th, 2005 907 days after the Columbia Disaster, thousands of man-hours of investigations, modifications, and preparations, Space Shuttle Discovery, now about to fly its second return to flight mission, sits at Launch Complex 39B, last graced by Atlantis for STS-112 in 2002. The writing now on the wall for the Shuttle Program it's final objective was to complete the International Space Station. STS-114 was originally slated to be a resupply mission and crew rotation mission, launching on March 1st, 2003 with the Raffaello MPLM. Now in 2005, launching the External Stowage Platform 2 or ESP-2, the Raffaello MPLM with supplies such as food, water, oxygen, experiments, and a replacement Control Moment Gyroscope for the Z1 truss. In addition, the crew would conduct several tests of in-space repairs in the event that the Thermal Protection System is compromised. STS-114 also had a similar crew to its original counterpart, omitting and replacing those who were scheduled to take part in Expedition 7. Commander Eileen Collins, Pilot James Kelly and Mission Specialists, Soichi Noguchi, Stephen Robinson, all were originally slated to fly on the original STS-114 with Andrew Thomas, Wendy Lawrence, and Charles Camarda replacing Yuri Malenchenko, Ed Lu, and Aleksandr Kaleri, of which Malenchenko and Lu would fly on a Soyuz to carry out Expedition 7. Being originally scheduled for launch on July 13th, Discovery experienced an anomaly with an LH2 fuel level sensor resulting in a scrub, NASA conducted meetings to discuss remedying the issue with the earliest liftoff date being placed on July 17th. Eventually, NASA scheduled the launch for the 26th despite not solving the fuel sensor anomalies. the crew stood by at 39B for launch at 9:39 AM EDT. 2.5 seconds into the flight, the External Tank struck a bird, but due to the low speed of collision and proximity to the orbiter, the collision was deemed a non-issue. Further on, the orbiter shed a 1.5 inch of thermal tile on the front landing gear door. Shortly after SRB separation, a 36 by 11 by 6-inch piece of external tank foam (expected to weigh half as much as the debris that doomed Columbia) was shed from the ET but did not strike the Orbiter. 20 seconds after that, another smaller piece separated and struck the Orbiter's right wing but was estimated to deliver 1/10th of the energy that would pose damage to the TPS. After reaching orbit, Discovery and the crew tweaked their course for a rendezvous with the ISS in two days' time. In the meantime, the crew would also be the first to use the Orbital Boom Sensor System. The Orbital Boom Sensor System or OBSS is a 50-foot boom arm carried by all Space Shuttles in response to the Columbia Disaster. Featuring a suite of imaging and analysis equipment, the OBSS is designed to observe the entire Thermal Protection System for damage. Constructed almost identically to the Canadarm, the OBSS had fixed joints so for it to be moved, it would be grappled by the Shuttle's Canadarm and maneuvered around to survey the TPS. The crew after completing the survey stow the OBSS and the ground begins to analyze the data. The aforementioned foam strikes are rendered non-issues but something else sticks out to the ground control. Two gap fillers installed into the Shuttle TPS are found to be protruding further out of the TPS surface than could pose a problem with airflow over the orbiter during reentry. This presents an opportunity for the crew to attempt new repair techniques on the backside of the TPS. (These gap fillers aren't integral for reentry. The purpose is to prevent heat stress damage of an orbiter over its lifetime. As a result, they can simply be removed while on orbit.) In addition, a loose thermal blanket was noted out the Commanders port window, but was rendered by the ground as a nonissue via wind tunnel analysis. The crew would continue to coast to the ISS where they would conduct the removal during an EVA. Discovery approached the ISS differently than previous missions, by approaching from the bottom and then holding in that position. This was another precaution born of the Columbia Disaster, the Rendezvous Pitch Maneuver (Otherwise known as the R-bar pitch maneuver or simply a backflip). Aboard the space station was Sergei Krikalev and John Phillips of Expedition 11, and with high zoom lenses, the crew would photograph the Orbiters TPS and send the images to the ground for analysis. The crew performs the Maneuver and then prepares to dock with the ISS via PMA-2 on Destiny. Authors Note: I have a personal soft spot for the RPM. Though born out of tragic circumstances, I believe its a testament to the beauty of space flight in general. It really embodies the dance in space that docking is with the jovial elegance of the flip. I feel that with the retirement of the Shuttle and by extension the RPM, that dance isn't as "Human" per se. I'd highly recommend checking out videos of it on Youtube. I'll get off my soap box now. Discovery docked with PMA-2 at 11:18UTC on July 18th, 2005 ending the two and a half year drought of visits from an orbiter. The first order of business would be to relocate Raffaello to the nadir port of Unity. It had been two and a half years since a Shuttle had last resupplied the station. In addition, the MPLM was the only way to return a substantial amount of cargo to Earth and as a result, the ISS had become quite full of various experiments and hardware that needed to be returned. Now with the MPLM docked for processing. The crew began to prepare for the three scheduled EVAs. All conducted by Stephen Robinson and Souichi Noguchi, they first prepared for EVA-1, a 6 hour 50 minute EVA with the crew attaching mounting hardware for ESP-2 onto the Quest airlock and testing various repair methods for the TPS. EVA-2 was conducted on August 1st, 2005, taking 7 hours and 14 minutes. The sole purpose of EVA-2 was the replacement of the failed Control Moment Gyro in the Station's Z1 truss. Used for Station orientation the Z1 truss has 4 CMGs 2 of which are needed for attitude and an additional two for redundancy. With only three functioning the failure of another would result in no active redundancy for attitude control apart from precious fuel stored in the Russian Segment. EVA-3 conducted on August 3rd, of 2005, had 2 main objectives, position the External Stowage Platform 2 on the side of the Quest airlock, and remove the two gap fillers on the belly of the Shuttle. But to reach the far side of the orbiter, the Station's robotic arm would grapple, the OBSS and Stephen Robinson would ride it to the belly and remove the gap fillers. After EVA-3 had concluded and the mission objectives met, the crew prepared to remove Raffaello from Unity and prepare to depart. At 05:14 UTC the hatches between the ISS and Discovery were closed and then undocked at 07:24 UTC ending the 8 day 19-hour stay aboard the ISS. The crew backed away conducted a fly-around of the station and then backed away to prepare for reentry procedures. After being delayed by weather at the Cape and being waved off by mission control twice, the crew prepared for landing a Edwards Airforce base on August 9th aft being waved off another two times by the Cape. At 04:09 AM PDT Discovery began the 2 minute 42 second deorbit burn and began to feel the effects of the atmosphere 28 minutes after the burn completed. At 5:08 Eileen Collins took Control of Discovery for final approach. Discovery Touched down at Edwards Runway 22 at 5:11 AM PDT and reported Wheels Stop 1 minute and 1 second later, about an hour before sunrise. The crew exited Discovery at 7:13 PDT. Discovery would flown back to the Cape via the Shuttle Carrier Aircraft. This mission took a really long time to make and I'm sorry for the delay but I had a heck of a time making it! A lot of things I had been working on changing and fixing. For example, I changed the Mobile Launch Platform Edwards, those new SRB Plumes from the Lemon_Cup himself! and the Visual Setup, which took a lot of troubleshooting, to this day Venus and Titan are mysterious voids! In addition, I had been trying to figure out what was causing my screenshots to be fuzzy, which happened to be KSP Anti Aliasing and Scatterer Anti Aliasing blending my screen . Then I had a continuity error where Canadarm 2 should have been on Destiny instead of the MBS so I had to reshoot the RPM and docking part of the mission. Due to the foam shedding on ascent, NASA stated that the earliest a Shuttle could be launched after STS-114 would be on 22 of September of 2005 but would eventually launch on the 4th of July 2006. The blame of both the Columbia disaster and the foam shedding on STS-114 had been blamed on the workers at Michoud Assembly Facility but x-ray photographs discovered that thermal expansion and contraction during filling of the tank caused the problems, exonerating the Michoud workers. NASA officials apologized to the workers. While the work continued on fixing the Shuttle External tank issues for STS-121, the ISS would continue to need resupplies and crew rotations from the Roscosmos. Coming Up: ISS Operation during H2 2005
