 Preparations were completed here at KSC's payload processing facilities, assembling the telescopes, performing the proper testing and the checkout. The three telescopes include the Hopkins Ultraviolet Telescope developed at the Johns Hopkins University in Baltimore, Maryland, the Ultraviolet Imaging Telescope developed by NASA's Goddard Space Flight Center in Greenbelt, Maryland, and the Wisconsin Ultraviolet Photo Polarimeter Experiment developed at the University of Wisconsin at Madison. The simultaneous observations by the three telescopes will complement one another. Shuttle Endeavour is poised at Launch Pad 39A, ready for the second launch of the year. All countdown events are on schedule and the launch team here in Fireroom 3 is not tracking any technical issues. That would prevent an on-time launch at 1.37 a.m. Eastern Time. The window extends today for two and a half hours or until 4.07. In just a few minutes, we will be getting live coverage of the flight crew sitting down to have their pre-flight meal. The crew has been divided up onto two teams, the red and the blue team, so that they can operate in two different shifts during the flight for 24 hours of data collection. And here we have the crew of Mission STS-67. Here we have Dr. Ron Paris, payload specialist flying on the shuttle for the second time today. Sitting next to him is Dr. John Grunsfeld also flying for the second time as a payload specialist. And we have the rookie pilot, Bill Gregory, Commander Steve Oswald flying for the third time today. payload commander Tamara Jernigan, she's also flying aboard the shuttle for the third time today. And we have Sam Durantz flying aboard the shuttle again. And we have rookie Wendy Lawrence, also the flight engineer. Crew will be going into weather briefing getting an update on conditions here at Kennedy Space Center and also at the trans-oceanic abort sites. Then they'll get into their launch and entry suits and ride out to the launch pad, climb aboard the shuttle and prepare for launch today. Countdown clock has remained at T-minus three hours and holding. Got about nine minutes remaining in this hold. Got about five minutes remaining in this built-in hold. At T-minus three hours and holding, this is shuttle launch control. Here we have the astronauts for STS-67 on the third floor of the operations and checkout building. We're now going to, coming down the hallway, going to an elevator. This is shuttle launch control. The STS-67 crew has arrived at launch pad 39A at the 195-foot level. Just getting out the elevators and they will be walking across the orbiter access arm. It's the pilot, Bill Gregory, just getting a wave here. Crew's getting ready to climb aboard the orbiter. All systems, all conversations on OIS channel 212 during astral commons checks will be heard by the crew. The channel should remain silent except for emergency calls. STS-67, CDR OTC. All right, George. STS, you verify each member of the crew is ready to proceed with astral commons checks. Endeavour OTC, during astral commons checks, adjust appropriate volume control at around 1, 2, ICOM-AMB and air-to-air for comfort. Do not change audio panel switch configuration. Endeavour OTC, count check on air-to-ground 1. How do you copy? Clear, CDR. CLT. MS-1. MS-2. MS-3. DS-1. DS-2. Good count check. We switch now to air-to-ground 2. DLS is go for OAA retract. The orbiter access crew arm is being retracted away from the vehicle and into the launch configuration. This arm can be extended in just a few seconds if necessary. OK, I've went 4 times 10 to the minus 50. OK, SDS out. Profile test of the orbiter's aero surfaces has started. Orbiter flight control surfaces are being moved through a pre-programmed pattern to verify they are ready for launch. The three main engines are being gimbled and positioned for launch. All systems are go for launch at this time, just a few minutes away from the eighth voyage of Endeavour with a crew of seven on a 16-day flight to study the invisible universe. Endeavour OTC, close and lock your visor. Make the 802 flow. And good luck on your record-setting 16-day mission. OK, we'll close them and start the flow. And in fact, Mr. Solomon is close to landing us his spaceship. And if Dr. Holly doesn't have his bag on yet, we do have to put it on now. T minus 20 seconds. Thousands of gallons of water will be dumped onto the launch platform in the next few seconds. 12, 11, 10, 9, 8, 7. We have a go for main engine start. 4, 3, 2, 1. We have booster ignition and liftoff of Endeavour on a voyage to view the universe. Houston now controlling. Roger roll, Endeavour. Way aboard Endeavour. The vehicle is now in a heads down position on course for a 28 and a half degree orbit. Endeavour's engines have now throttled down as the orbiter passes through the area of maximum dynamic pressure on the vehicle in a lower atmosphere. Endeavour's already two miles down range from the launch site. Traveling more than 1,000 miles per hour. Endeavour, Houston, go ahead and throttle up. Roger, go ahead, Houston. The three liquid fuel engines are back at full throttle aboard Endeavour. At the 1 minute 30 second mark, Endeavour is traveling 1,700 miles per hour. The altitude is 82,000 feet down range from the launch site, 12 nautical miles. Standing by for burnout and separation of the twin solid rocket boosters. An SRB separation is confirmed aboard Endeavour at the 2 minute 15 second mark. The vehicle is at an altitude of 178,000 feet down range from the launch site, 38 nautical miles. Endeavour is now traveling 4,500 feet per second or 3,000 miles per hour. Roger, your performance is nominal. ATC, get ready. Go ahead. Please step 799 complete. GLS is go for ET-LO2 pressure station. 10. GLS is go for main engine start. Royal program, Houston. Roger, roll Endeavour. It's like eyes we see good roll. Copy. Throttle up 3 at 104. Endeavour, Houston, go ahead and throttle up. Roger, go, Houston. Performance nominal? 103, converge. Endeavour, Houston, performance nominal? Roger, performance is nominal. 2-engine bin gear. Endeavour, Houston, 2-engine bin gear? 2-engine bin. Endeavour, Houston, negative return? Roger, add Houston, negative return. Goodbye for pressed ATO. Mark. Endeavour, Houston, press to ATO, select ban jewel. Best ATO, select ban jewel. Space shuttle Endeavour. This is where we spend a lot of our off-duty hours. You'll notice on the far wall, we have some sleep stations installed. This is very important for our flight. We have a crew of seven, and we're up 24 hours a day as we split ourselves into two shifts. The red team is asleep right now. The sleep stations provide them with the privacy they need to get a good night's rest. They'll be waking up in a few hours, coming on duty. The white containers that you see Velcro to the wall contain our personal hygiene kit. In the waitlist environment, it's really important to have Velcro around. Otherwise, everything will float. The mid-tech also provides us with an opportunity to carry some smaller experiments. You're looking at two of them right now. One of them was sponsored by Massachusetts Institute of Technology to experiment in control systems theory. We're actually doing some work for a future space station that we're going to develop. Our experiment is a protein crystal growth experiment, as are the two that I'm standing to right now. So an ongoing research project that's flown on many shuttles, we found that we can grow more pure crystals when we're up in this waitlist environment. Well, let's go see the rest of the shuttle. Oh, here's Tammy. She's taking a break from her work to get herself something to drink. She's actually over in that area that you could call the kitchen or the galley. It's got a means to dispense water so we can fill our drink bags and also rehydrate our food. Most of the fluid on board is freeze-dried, and some of it is what we call thermostabilized, where all we have to do is throw it into the small oven we also have on board. You can see on the controls on the right-hand side that we have a means of selecting the amount of water and whether or not we want hot or cold. We also have a small oven down below this rehydration station, which Tammy is getting into right now. I think she's going to pass up some food to Sam. He doesn't get an opportunity to come down much since the experiments, and the telescopes keep him so busy. That's the only way to do it. Waitlessness is great. Well, I guess Tammy's got to go back up to work. Here, let me give you a better view. Like I said, we have a means of filling up the freeze-dried packages we have on board, and a means of heating them as well. You can see some of the food that's Velcroed to the wall. This is Base Live Operations Senseful. We're again seeing real-time video from Endeavour from the Hopkins Ultraviolet Telescope seeing the Finder camera image as the telescope is now trained on Jupiter and its moons. We're using two of the moons as so-called guide stars. Those are the moons Europa and Ganymede, which the crosshairs are focused on. The actual moon Io, which is the subject of observation here, should be showing up within the crosshairs right in the center of the screen on NASA TV. And, of course, the large, just white disk about the size of a nickel is Jupiter itself, the large red planet of our solar system. Down at the bottom of the screen, we can see that we're taking data with the Hopkins Telescope Spectrometer to try and measure elements that are showing up in the ejection of material by volcanoes on the moon Io. Houston, I think we're going to, the same reason this is where the T-ACC is taking out all those science things, all those crew reference guys are gone, so there's not going to be any photo TV 97. You'll be welcome to come over to the flight deck if you want, but no previous word of damage. Copy, Sam. Other than the base that we did last night, that'll be the end of that. Okay. This real-time video downlink from the guidance system of the Hopkins Ultraviolet Telescope shows the globular cluster 47 to Connie, which is a primary target for this orbit. The stars are extremely numerous and quite bright ground operations. Teams are working with the on orbit astronauts to determine the precise pointing of... Astro Huntsville, we'll go for line 41, detector on. Okay, John, if you see good act marks, item six, the re-center, and then followed by an item... Stand by one. And three, CJ Anberg, Cheney Middle School. This is WA4SIR. Hi, Nick. Well, it's good to hear you on the air here and we're ready to... ready to talk to you guys. Go ahead. Okay, copy that now. Yeah, well, you know, when I was in the fourth grade, the Mercury program was in full swing and I used to watch the Mercury launches and my teacher would bring a TV into school and I would watch them all. And I got really excited about it then and I think ever since then it was sort of in the back of my mind that flying in space is something that I really wanted to do. I think the human race could live on other planets. In fact, I would very much like to see us colonize Mars. I think Mars is a great, great expansion area for us because it's a little bit like the Earth in the way it's built and it could be built into a planet that humans could survive on pretty well, I think. Space station mayor, space station mayor. This is Space Shuttle Endeavor. Howdy here. Dr. Seigert, I presume. I'm not sure how your English was by now, Normie, but it sounds like you haven't forgotten that thing. Probably still. Your new home, Dr. Seigert, you all settled in? It's not bad at all. It's nice and lonely and places that are cool and places that migrate to wherever is most comfortable to this team. After the scenery around where I am, I've got six other faces that looks an awful lot like Discovery did back in 92, Norm. Well, you know, I figured if we were ever in orbit again, we'd probably be on the same spacecraft, I guess I was wrong. Amazing, we've got 13 human beings in orbit right now, and I think that you're just starting off on your big adventure and we're about to end ours tomorrow. But I think the fact that we've got 13 humans on orbit is signaling that we've got a whole new horizon just unfolding for us here with our joint space efforts. And we're real happy for you. Well, I'm happy for you. I believe you've had a successful flight. Everyone on board asked me to pass along their best wishes to you and in the Russian tradition, we'll use your wires on the hockey success. We sure appreciate the words and we've had just a great flight here. The orbiter's been working just great. We've gathered a lot of ultraviolet data for the guys on the ground and we're hoping to come home tomorrow after the weather lets us and if not, we'll just be forced to spend an extra day on orbit. Endeavour Houston, about a minute to LOS, we'll pick you up on the other side at 2125 and it looks like we have a view of some sort of tropical cyclone sort of system out there in the Indian Ocean. There's a lot of serious blow off there. We certainly have some clouds out here, Mario, and I guess we'll see you on the other side of the LOS. Catch you then. Go ahead, John. Yeah, to pass the acquisitions, the IPS has been pointing a little bit off and this one, as soon as we commended the Astro Star Trek, it was almost right on with the star view display we have up here. Seeing some amazing lightning from our downlink cameras, Endeavour. I had a picture with the lightning in the sunset. It's an incredible view. Cape, very clearly. Astro Huntsville, Toronto. That was a great job. We've got an awful lot of observations and data. IPS performed fantastic. The Astro payload did too. As did the crew. I guess it's time to get close to Stowe, our orbiting astrophysics laboratory. We'll press along with that, David. It's sad thing this beautiful instrument go to the stowage position. Well, it's been a fine job for us and we're well pleased to have been part of the mission, Dave. We have tried to downlink camera A. I don't know if you have TV available. We've put it up on camera A if you do. Affirmative. Thank you. We're getting a great image. Good morning, Tammy. Endeavour now being commanded into its first roll reversal. This is a maneuver to bank the orbiter from left to right or vice versa to increase the drag during the entry, thus slowing the airspeed of the orbiter and dissipating the proper energy on the command of the onboard computers. Gary Houston, we show you approaching the hack. No change to whether the winds are 2, 3, 0 at 15 peak 22 at 3 peak 4 from the right. 15 peak 22 on the head. We would like a late drag-shoot deploy just in case we can get the crosswind DTO. Endeavour is traveling right now at a descent rate 7 times steeper than that of a commercial jetliner as Oswald prepares to flare up the nose prior to landing. Bill Gregory has deployed the landing gear, main gear touchdown, nose gear touchdown. The drag-shoot has been deployed. Endeavour rolling out on runway 22 at Edwards Air Force Base to complete a shuttle record 6.9 million mile astronomy research flight. Copy. We'll stop. Endeavour and welcome home Endeavour after a fantastic record-setting mission. It'll be a tough one to beat and it sure is nice to have you all home. Okay, Oswald copy. Okay, post-landing Delta's copy. We'll stop. Endeavour and welcome home Endeavour after a fantastic record-setting mission. It'll be a tough one to beat and it sure is nice to have you all home. It's nice to be here. Max, no Delta's copy. No immediate Delta's. He's got to pick up on the post-landing. Gary Houston, go post-landing Delta's and your go to pick up in a post-landing procedure. Okay, GNC flight. Flight GNC, any other Delta's? Negative procedure. Endeavour, E.T. and Buckel doors are open. We would like the hydraulic load test. Endeavour Houston, you have a go for the hydraulic load test. E.T. doors look good.
