[Man] So Bob Behnken hopping on the comms there. 405 00:24:18,044 --> 00:24:21,008 He used the acronym, or I guess the letters, PLT, 406 00:24:21,008 --> 00:24:23,897 for pilot- 407 00:24:23,897 --> 00:24:26,552 - [Man on Radio] Okay, we're donning our gloves at this time. 408 00:24:26,552 --> 00:24:29,252 - [Anna] We copy. 409 00:24:31,044 --> 00:24:34,716 - [Man] So for ISS missions for NASA, 410 00:24:34,716 --> 00:24:37,024 there are four seats on the Dragon spacecraft. 411 00:24:37,024 --> 00:24:39,795 If you were looking in from the side hatch, 412 00:24:39,795 --> 00:24:42,275 it would be seat one on the far right, 413 00:24:42,275 --> 00:24:44,721 all the way counting up to seat four on the far left. 414 00:24:45,599 --> 00:24:47,182 Doug Hurley in the 415 00:24:47,182 --> 00:24:49,313 commander, or CDR, seat, 416 00:24:49,702 --> 00:24:51,428 that's seat number two. 417 00:24:51,428 --> 00:24:53,609 So that would be the 418 00:24:53,609 --> 00:24:55,597 second seat on the... 419 00:24:55,597 --> 00:24:58,852 Second seat from the window, yeah.

[Dan] Alright, so at this point we're inside the approach ellipsoid that we were talking about. 784 00:43:40,354 --> 00:43:46,724 So as Dragon moves inside of just about one kilometer away, 785 00:43:46,724 --> 00:43:50,506 again the approach ellipsoid is an elliptical shape 786 00:43:50,506 --> 00:43:55,725 four kilometers long by two kilometers tall by two kilometers wide. 787 00:43:55,725 --> 00:43:58,034 Essentially a three dimensional oval. 788 00:43:58,034 --> 00:44:01,025 That's just one of those checkpoints around the station 789 00:44:01,025 --> 00:44:05,094 that governs the approach of visiting vehicles. 790 00:44:05,094 --> 00:44:07,047 Before we were in this point, 791 00:44:08,857 --> 00:44:11,046 before we were in this point, 792 00:44:11,046 --> 00:44:15,695 Dragon was on a 24 hour free-stage trajectory. 793 00:44:15,695 --> 00:44:17,160 So if we had lost control of Dragon, 794 00:44:17,160 --> 00:44:20,662 it would have been at least 24 hours before we moved inside. 795 00:44:20,662 --> 00:44:24,739 So we're now inside this approach ellipsoid, Dragon given the go 796 00:44:24,739 --> 00:44:28,716 as it was given the authority to do the approach initiation burn. 797 00:44:31,405 --> 00:44:34,455 So that next imaginary gateway around the Space Station is 798 00:44:34,455 --> 00:44:37,166 the keep-out sphere, that one is a little bit smaller, 799 00:44:37,166 --> 00:44:41,952 it has a radius of only 200 meters, and we won't be crossing that until 800 00:44:41,952 --> 00:44:45,899 we're done with the manual flight test, but we'll do the go, no-go 801 00:44:45,899 --> 00:44:50,717 to cross that sphere well in advance of them actually moving in. 802 00:44:53,698 --> 00:44:58,395 - [Man] And about 14 minutes from now there'll be a small correction maneuver to 803 00:44:58,395 --> 00:45:03,850 to take us from Waypoint Zero to Waypoint One, right outside the keep-out sphere. 804 00:45:08,258 --> 00:45:10,698 So if we have a video of Dragon at that point, you may see the 805 00:45:10,698 --> 00:45:13,051 Draco thrusters firing. 806 00:45:18,284 --> 00:45:20,805 Right now, the vehicle looking healthy as it's making its way towards 807 00:45:20,805 --> 00:45:27,459 that RBAR approach just 400 meters below the International Space Station. 808 00:46:02,450 --> 00:46:05,248 That's a pretty dramatic shot of Dragon as it continues to close in. 809 00:46:05,248 --> 00:46:08,350 The Station and Dragon right now just over the 810 00:46:08,350 --> 00:46:10,525 northeastern part of China. 811 00:46:10,525 --> 00:46:12,807 They are in an orbital nighttime. 812 00:46:12,807 --> 00:46:15,756 So the sun is setting on both vehicles right now 813 00:46:15,756 --> 00:46:20,804 as they're flying about 262 statute miles over the surface of planet Earth. 814 00:46:20,804 --> 00:46:25,681 Two crewmembers, NASA's Bob Behnken and Doug Hurley inside Dragon, 815 00:46:25,681 --> 00:46:28,461 closing in on their home for the next several months, 816 00:46:28,461 --> 00:46:33,392 completing the first crew flight of the Commercial Crew Program era 817 00:46:33,392 --> 00:46:35,779 to the International Space Station. 818 00:46:35,779 --> 00:46:40,590 So we should be under two hours away from the planned docking time. 819 00:46:40,590 --> 00:46:46,122 We're looking at a docking around 7:30am over here on the West Coast. 820 00:46:46,122 --> 00:46:50,263 But they were able to move through a number of their maneuvers a little bit quicker. 821 00:46:50,263 --> 00:46:54,003 We're right about 16 minutes ahead of the approach initiation burn. 822 00:46:54,003 --> 00:46:57,278 So that docking time will be a little bit variable 823 00:46:57,278 --> 00:47:00,500 and will hinge on how quickly they're able to move through that 824 00:47:00,500 --> 00:47:02,926 second manual flight test. 825 00:47:02,926 --> 00:47:05,953 Everything continuing to go smoothly. 826 00:47:05,953 --> 00:47:08,942 We're waiting for their arrival at Waypoint Zero. 827 00:47:08,942 --> 00:47:12,271 Should be coming up in just about 12 minutes from now. 828 00:47:15,635 --> 00:47:19,066 Alright, so we heard both teams, the NASA and SpaceX teams, 829 00:47:19,066 --> 00:47:22,262 are go to continue on past Waypoint Zero. 830 00:47:22,262 --> 00:47:26,099 So they'll be coming up on that point about 10 minutes from now. 831 00:47:26,099 --> 00:47:31,797 And they're just going to continue on along up until Waypoint One. 832 00:47:31,797 --> 00:47:34,642 So it'll be a quick pass through. 833 00:47:34,642 --> 00:47:37,330 They'll go from just 400 meters directly below the International Space Station 834 00:47:37,330 --> 00:47:39,579 up to Waypoint One. 835 00:47:39,579 --> 00:47:41,911 So they're going to do pretty much a 90 degree maneuver 836 00:47:41,911 --> 00:47:45,836 to go from directly below Station to directly in front of it. 837 00:47:47,700 --> 00:47:49,599 And this is always something really cool to see. 838 00:47:49,599 --> 00:47:53,318 So you're seeing city lights on the ground below Dragon right now 839 00:47:53,318 --> 00:47:56,500 as we continue to fly. 840 00:47:56,500 --> 00:48:00,009 We just made a pass over Japan, so those are city lights in Japan 841 00:48:00,009 --> 00:48:04,133 as Dragon and the Station just made a passover and now they're about to 842 00:48:04,133 --> 00:48:07,245 cross over the northern Pacific Ocean. 843 00:48:07,245 --> 00:48:09,867 Things will be dark for a little while 844 00:48:09,867 --> 00:48:12,302 as Dragon continues to close in. 845 00:48:12,302 --> 00:48:17,489 We should have sunrise coming up in about 21 minutes after the hour. 846 00:48:17,489 --> 00:48:20,064 So if everything holds on track, 847 00:48:20,064 --> 00:48:23,211 we should have some good sunlight for docking, hopefully. 848 00:48:23,211 --> 00:48:27,077 But we'll have lights onboard the Dragon itself. 849 00:48:27,077 --> 00:48:31,505 You can see the red and the green, telling us where it is as 850 00:48:31,505 --> 00:48:34,462 it continues to approach. 851 00:48:34,462 --> 00:48:39,234 At this moment, we are just about 585 meters away. 852 00:49:15,620 --> 00:49:17,812 All right, in just about eight minutes we're going to pass through 853 00:49:17,812 --> 00:49:22,077 Waypoint Zero and continue on to Waypoint One. 854 00:49:22,077 --> 00:49:26,103 And then shortly after that, the crew is going to get their second chance to jump 855 00:49:26,103 --> 00:49:29,644 in and start sending some commands to Dragon. 856 00:49:29,644 --> 00:49:33,489 - [Man] That's right, on the displays they'll 857 00:49:33,489 --> 00:49:37,619 they have some commands in the upper right-hand corner. 858 00:49:37,619 --> 00:49:41,348 We got a little sneak peek at that while they did one of their 859 00:49:41,348 --> 00:49:44,247 video sessions showing us the displays earlier in this mission. 860 00:49:44,247 --> 00:49:52,108 They'll command a hold once they get to about 220 meters away from the Station. 861 00:49:52,108 --> 00:49:55,921 That's where they'll conduct that manual piloting test. 862 00:50:00,352 --> 00:50:02,853 - [Dan] And again, this will be their second manual piloting 863 00:50:02,853 --> 00:50:04,904 of the Dragon spacecraft. 864 00:50:04,904 --> 00:50:07,451 We were able to watch them yesterday. 865 00:50:07,451 --> 00:50:09,961 (indistinct radio chatter) 866 00:50:09,961 --> 00:50:13,092 Yesterday, shortly after getting on orbit, 867 00:50:13,092 --> 00:50:17,381 they were able to take control of Dragon and go through a number of pointing maneuvers, 868 00:50:17,381 --> 00:50:19,741 or attitude adjustments. 869 00:50:23,312 --> 00:50:26,753 And in this case they're going to be doing pretty much the 870 00:50:26,753 --> 00:50:29,197 second half of everything. 871 00:50:29,197 --> 00:50:31,928 When you're flying a spacecraft, you're worrying about attitude adjustments 872 00:50:31,928 --> 00:50:34,540 and then you're worrying about translational adjustments. 873 00:50:34,540 --> 00:50:38,107 And this is going to be their chance to do those translational maneuvers. 874 00:51:24,194 --> 00:51:27,653 - [Man] Yeah, and once they finish that manual piloting test then 875 00:51:27,653 --> 00:51:30,794 Dragon will take over. 876 00:51:30,794 --> 00:51:33,957 They'll transition and go towards Waypoint Two. 877 00:51:35,523 --> 00:51:37,998 That'll put them just 20 meters away from Space Station. 878 00:51:40,287 --> 00:51:43,107 - [Dan] All right, well, as we're just about five and a half minutes 879 00:51:43,107 --> 00:51:46,498 away from their arrival and quick pass through Waypoint Zero, 880 00:51:46,498 --> 00:51:49,780 let's jump over to Gary Jordan over at Mission Control Houston 881 00:51:49,780 --> 00:51:53,907 to check how everything is lining up with the teams in Houston 882 00:51:53,907 --> 00:51:56,248 for this approach and docking. Gary? 883 00:51:59,289 --> 00:52:02,281 - [Gary] Thanks, Dan, really good to see Dragon. 884 00:52:02,281 --> 00:52:04,870 Bob and Doug inside of 500 meters. 885 00:52:04,870 --> 00:52:07,239 So close to the International Space Station. 886 00:52:07,239 --> 00:52:09,534 Just flying through all of the milestones we have 887 00:52:09,534 --> 00:52:13,078 to get towards docking, towards the International Space Station. 888 00:52:13,078 --> 00:52:15,685 A lot of prep work went into this moment. 889 00:52:15,685 --> 00:52:20,099 Just previously we transitioned control of Station's attitude 890 00:52:20,099 --> 00:52:22,316 to Russian thrusters. 891 00:52:22,316 --> 00:52:24,420 Also configured the Station itself 892 00:52:24,420 --> 00:52:27,426 for the docking attitude. 893 00:52:27,426 --> 00:52:30,552 Chris Cassidy was just finishing up his midday meal. 894 00:52:30,552 --> 00:52:34,396 His next activity, just a little bit more than 20 minutes from now, 895 00:52:34,396 --> 00:52:37,190 will begin to set up for Dragon monitoring. 896 00:52:37,190 --> 00:52:39,554 He has a tool called the RPOP. 897 00:52:39,554 --> 00:52:43,346 We'll be to display some of the telemetry data coming from Dragon 898 00:52:43,346 --> 00:52:45,104 through the C2V2, 899 00:52:45,104 --> 00:52:48,212 this is the Common Communication for Visiting Vehicles. 900 00:52:48,212 --> 00:52:51,943 This established a link between the International Space Station and Dragon. 901 00:52:51,943 --> 00:52:55,915 Dragon's telemetry, data, all the information being relayed 902 00:52:55,915 --> 00:52:58,067 through the International Space Station. 903 00:52:58,067 --> 00:53:02,354 And Cassidy will be able to monitor from this tool, 904 00:53:02,354 --> 00:53:04,773 again setting up in just about 20 minutes. 905 00:53:04,773 --> 00:53:08,902 Everything going according to plan from the International Space Station side of things. 906 00:53:08,902 --> 00:53:13,046 We're getting great views from Dragon of the International Space Station, look at that. 907 00:53:13,046 --> 00:53:17,509 The lights reflecting from the outside of the International Space Station. 908 00:53:17,509 --> 00:53:21,282 Turned on so Bob and Doug have a very clear view 909 00:53:21,282 --> 00:53:23,418 of the International Space Station. 910 00:53:23,418 --> 00:53:26,188 Should be entering into an orbital sunrise here shortly. 911 00:53:26,188 --> 00:53:31,943 From there, we'll take you through the next few maneuvers, 912 00:53:31,943 --> 00:53:36,189 again passing Waypoint One and going right into that manual flight test. 913 00:53:36,189 --> 00:53:38,293 Again, everything here from Mission Control Houston, 914 00:53:38,293 --> 00:53:41,985 International Space Station configured for docking, everything's go from our end. 915 00:53:41,985 --> 00:53:44,265 Back over to you in Hawthorn. 916 00:53:44,265 --> 00:53:46,446 - [Dan] All right, thanks, Gary. 917 00:53:46,446 --> 00:53:50,317 We're jumping in now with Bob and Doug inside the Crew Dragon. 918 00:53:50,317 --> 00:53:54,911 Again you're able to see what they're looking at on those displays there. 919 00:53:54,911 --> 00:53:58,380 And there's the view from the Dragon spacecraft itself. 920 00:53:58,380 --> 00:54:02,082 You can see the International Space Station continuing to close in. 921 00:54:02,082 --> 00:54:05,014 Right now they're only about 430 meters away. 922 00:54:05,014 --> 00:54:09,159 They're going to be quickly passing through Waypoint Zero in the next three minutes, 923 00:54:09,159 --> 00:54:11,583 and they're going to continue their way 924 00:54:11,583 --> 00:54:15,512 up to waypoint number one 925 00:54:15,512 --> 00:54:20,032 which is about 220 meters outside, out in front, 926 00:54:20,032 --> 00:54:22,388 of the Station itself. 927 00:54:27,661 --> 00:54:31,606 - [Man] Yeah, and Dragon has a number of relative navigation sensors 928 00:54:31,606 --> 00:54:34,690 items that are used for guidance and control of the vehicle. 929 00:54:34,690 --> 00:54:38,010 So right now Dragon is in a pointing mode that 930 00:54:38,010 --> 00:54:42,738 has those relative navigation sensors trained on the Space Station, 931 00:54:42,738 --> 00:54:47,558 with the attitude control system making minor adjustments as it needs to 932 00:54:47,558 --> 00:54:51,808 if there's any roll correction or anything it needs to perform. 933 00:54:51,808 --> 00:54:55,695 And Bob and Doug getting closer and closer to that manual flight test. 934 00:54:57,276 --> 00:55:00,493 They looked pretty comfy in those seats with that view right behind them. 935 00:55:00,493 --> 00:55:03,801 - [Dan] Yeah, they are suited up, and again, 936 00:55:03,801 --> 00:55:09,397 they get suited up for anything we consider kind of the dynamic operations inside the spacecraft. 937 00:55:10,882 --> 00:55:13,737 So anytime that they're either 938 00:55:13,737 --> 00:55:17,367 in an approach and docking maneuver, undocking maneuver, 939 00:55:17,367 --> 00:55:20,061 and then the very start and end of their missions, 940 00:55:20,061 --> 00:55:24,726 which are probably the most dynamic phases, that launch and ascent. 941 00:55:24,726 --> 00:55:27,152 And then that deorbit and splashdown 942 00:55:27,152 --> 00:55:30,036 when they come home and splash down in the Atlantic. 943 00:55:30,036 --> 00:55:34,227 We are just 420 meters away from the Space Station, 944 00:55:34,227 --> 00:55:36,496 less than a third of mile. 945 00:55:36,496 --> 00:55:40,617 Should be just about a minute a half before we're passing through Waypoint Zero 946 00:55:40,617 --> 00:55:42,964 and then Dragon's going to begin the... 947 00:55:42,964 --> 00:55:47,501 A little over 20 minute, about a 25 minute trip 948 00:55:47,501 --> 00:55:49,723 up to the docking access. 949 00:55:49,723 --> 00:55:52,112 So this'll be Waypoint One. 950 00:55:52,112 --> 00:55:54,382 They'll be 220 meters directly in front of the Station 951 00:55:54,382 --> 00:55:58,391 and they'll be lined up perfectly with that international docking adapter 952 00:55:58,391 --> 00:56:01,792 at the very forward port of the Node 2 module, 953 00:56:01,792 --> 00:56:04,763 also known as Harmony on the Space Station. 954 00:56:11,725 --> 00:56:14,176 - [Man] And there'll be a small attitude correction there 955 00:56:14,176 --> 00:56:19,312 The navigation and prop specialists on our team will monitor that burn. 956 00:56:19,312 --> 00:56:22,239 Then hopefully we'll hear some words from the core to the crew 957 00:56:22,239 --> 00:56:27,489 letting them know we have a good course correction towards Waypoint One. 958 00:56:32,526 --> 00:56:33,897 - [Dan] And again, things a little bit dark right now. 959 00:56:33,897 --> 00:56:37,806 We should have sunrise in about 25 minutes. 960 00:56:40,080 --> 00:56:43,458 And so things will get closer as we get to that manual flight test. 961 00:56:43,458 --> 00:56:48,649 And hopefully by the time we're there, we'll be right in front of the Station itself. 962 00:56:48,649 --> 00:56:54,103 We should get some good light on Dragon and some views from the Station 963 00:56:54,103 --> 00:56:58,306 looking straight out at the spacecraft, using the cameras that are 964 00:56:58,306 --> 00:57:01,201 right next to that docking port on Node 2. 965 00:57:01,201 --> 00:57:03,918 And Bob and Doug will once again take the controls 966 00:57:03,918 --> 00:57:07,282 using those touchscreens to maneuver Dragon. 967 00:57:07,282 --> 00:57:10,056 They'll do a number of translational maneuvers 968 00:57:10,056 --> 00:57:14,044 So physically moving the Dragon spacecraft in space. 969 00:57:14,044 --> 00:57:16,791 Oh, we're seeing some thruster firings there. 970 00:57:20,181 --> 00:57:24,717 And so those are using, some of them we call them the service section Draco thrusters. 971 00:57:24,717 --> 00:57:28,881 There are 12 around the lower part of the Dragon spacecraft. 972 00:57:42,927 --> 00:57:44,880 - [Man] So if you're just joining us- 973 00:57:44,880 --> 00:57:48,554 - [Man on Radio] Dragon on the Big Loop for Chris. 974 00:57:48,554 --> 00:57:51,457 Dragon is now transmitting docking camera video. 975 00:57:51,457 --> 00:57:55,924 We want to confirm that video and data is updating on Dragon 2 docking monitor. 976 00:58:06,528 --> 00:58:08,307 - [Man on Radio] Confirmed. 977 00:58:08,307 --> 00:58:11,405 - [Man on Radio] Copy confirmed, thanks. 978 00:58:23,366 --> 00:58:25,035 - [Man] So as I was mentioning earlier, 979 00:58:25,035 --> 00:58:30,891 if you're just now joining us, Dragon is now just 220 meters in front of the Space Station. 980 00:58:32,400 --> 00:58:35,428 The astronauts aboard, Bob Behnken and Doug Hurley, 981 00:58:37,420 --> 00:58:38,968 have commanded a manual hold, 982 00:58:38,968 --> 00:58:41,977 that's to perform a manual piloting test. 983 00:58:41,977 --> 00:58:47,270 There is a very nice shot 984 00:58:47,270 --> 00:58:51,073 of the Dragon vehicle from cameras aboard the Space Station. 985 00:58:51,073 --> 00:58:54,868 You just saw one of the Draco thrusters there firing. 986 00:58:54,868 --> 00:59:01,694 Just to keep it in that hold attitude right in front of the Station. 987 00:59:05,269 --> 00:59:08,851 - [Dan] Yeah, we have two cameras on the very forward port of Node 2, 988 00:59:08,851 --> 00:59:12,535 so right where Dragon is going to be headed following 989 00:59:12,535 --> 00:59:16,246 the completion of this manual piloting test. 990 00:59:18,970 --> 00:59:23,545 - [Anna] Dragon SpaceX on Big Loop, C2V2 link reconfiguration is complete. 991 00:59:23,545 --> 00:59:27,339 The soft capture ring extension is also complete. 992 00:59:30,801 --> 00:59:32,423 - [Man on Radio] Dragon copies on the Big Loop. 993 00:59:32,423 --> 00:59:36,752 Good ring extension and C2V2 reconfig. 994 00:59:47,385 --> 00:59:51,158 - [Man] So those comms on the Big Loop, the core, 995 00:59:51,158 --> 00:59:55,079 the crew operations and resources engineer here at SpaceX 996 00:59:55,079 --> 00:59:58,205 letting the crew know that
