series of undocking burns and we’ll see physical separation of the dragon from the international space station as mentioned earlier the relocation will free up harmony’s forward port for docking for the docking of another commercial spacecraft built to carry humans boeing’s cst-100 starliner here’s the new docking location for today and here’s of course the starliner that’ll be coming up on july 30th and arrive at the station uh about 24 hours later launching on july 30th first set of hooks open and nominal news there call out the first set of hooks is open and we’re now going to listen in for the call of opening the second set of hooks as the second set of hooks continue to drive it will be very shortly after they are finished driving and we have successful confirmation that those last set of hooks are are done uh from unlatching uh very shortly after that we should be seeing physical separation from this camera view uh that docking target you’re seeing right at the crosshairs the center of the camera view from the dragon itself uh we’ll start to see that view getting a little bit smaller as dragon itself backs straight away to the 60 meter mark and two short bursts to break the stiction between it and the docking port and physically separate from station so we’ll be able to see that here just momentarily all hooks open and nominal okay as you can see there undocking confirmed of crew dragon endeavor from the international space station on time at 5 45 am central 10 45 gmt while station and dragon flew approximately 263 miles over the south pacific flying west of chile dragon separation visually confirmed copy dragon spacex on the big load relocate also heard the call out there that the relocate burn was complete that was the final of the three burns of the uh the service section draco’s performed that final relocation lasted about 21 seconds dragon already about 50 meters away from the station it’s heading to a 60 meter hole point before transferring to the new docking axis dragon is working to acquire lidar tracking which will be used by dragon to autonomously execute this relocation maneuver like gary mentioned before we expect it to back straight away to about 60 meters station on the big loop is thrusters are enabled copy you’re getting a live view from the international space station dragon spacex on the big loop we’ve confirmed good position within the corridor and will be commanding go to relocate shortly you are go to raise your visors okay we’re looking good in the corridor here to raise our visors what you’re hearing now is all the teams in mission control houston and from this view here mission control in hof agreeing to uh transfer from one docking access to the other uh dragon now holding in front of its uh uh original docking access uh undocking from the forward harmony port right on time 5 45 a.m central time it’s a little bit further than 60 meters 95 meters and holding but from here the teams are looking to make sure that everything’s good before initiating that transfer maneuver it’ll move really from where it is now in front of the international space station to directly above it that’ll be the new docking access right in front of the ida 3 docking port from the external cameras of the international space station you can see there in the distance uh the crew dragon holding right now at about 87 meters from its original docking port teams are analyzing the uh the making sure that crew dragon itself is ready to for the next maneuver to transition to the new docking axis right now you can see it directly in front of its original docking port it’ll swing upwards from this view to the new docking port that’s on the zenith or space-facing side of the international space station’s harmony port now getting views from the international space station flight control room will be losing the views from the outside of the station periodically throughout today’s coverage uh and during the transition maneuver we’ll briefly describe why this is occurring uh it is in part due to the location of dragon relative to the tdrs satellites uh but as we are uh looking at the live view from the international space station flight control room we’re watching the uh dragon itself move inward toward that 60 meter hold point it went out uh commanded hold to at 60 meters and moved out to about 95 meters now it’s about 80 meters from the international space station teams are just analyzing making sure the dragons in the right place and everything is configured getting ready to execute that transition maneuver from one docking axis to the other in case you lilly dragon is about 70 meters away from station 10 meters to go back to these teams here in the international space station monitoring crew dragon as it makes its way back to the 60 meter hold point now at about just under 62 meters we’ll be arriving there shortly they’re also configuring the international space station itself it has a series of steps through the relocation maneuver the solar arrays themselves are feathered and locked in a position throughout the duration of today’s maneuver and attitude control has since been handed over to the russian segment uh from here uh the uh adco the attitude determination and control officer has been given the go to uh transition to the docking attitude this will hold international space station in the position ready for when the crew dragon endeavor makes its relocation maneuver to the new docking axis station will be in the predicted attitude position ready to receive dragon and receive confirmation dragon has arrived at the 60 meter hold point for those just joining you’re looking at a live view of mission control in hawthorne teams there are working with teams here in mission control houston monitoring the port relocation maneuver of crew dragon endeavor crew dragon undocked on time 5 45 am central time moving out with a commanded hold at 60 meters as it drifted out to about 95 meters and slowly made its way back to the 60 meter hold point now it’s holding steady we’re just waiting for that go to initiate the transition maneuver from the original docking axis where crew dragon has been calling its home uh for the past 89 days at the forward harmony port it’ll be transitioning to the zenith or space-facing port uh where it will have where it will that will be its new home until it departs in the fall on the bigfoot you see we’re holding spacex copies and confirms uh we are holding at the 60 meter hold point we are awaiting ground go to begin the access maneuver we’ll come back on board when ready as gary mentioned this crew 2 capsule it will remain at this port until it returns to earth uh in a couple of months but before it does that it’ll get a visit from the new crew 3 crew as they will be using the ida ii port where this dragon capsule just left and similarly to how we had a full health with two dragon two crew dragons on station at once both crew one and crew two we will have a similar on the big loop ground will be commanding relocate transfer to begin the access transition as a reminder the soft capture ring deploy will begin and relocate to access and we’re ready and station houston on the big loop monitor per block delta step 3 and one decimal 602 dragon departure monitoring copy and work once again you’re getting a live view from the flight control rooms in mission control hawthorne teams there working with teams here in mission control houston uh monitoring to today’s operation we had a good commanded hold at 60 meters in front of the new docking access and teams initiated the relocation maneuver now we are on our way the crew dragon itself from the original docking access to the new docking axis in front of the zenith port teams here in mission control houston have confirmed that that motion from the original docking access to the new one is looking good uh crew dragon on the expected trajectory to arrive at its new docking axis in the meantime the international space station itself has been configured for its docking attitude making sure that when crew dragon arrives on the new docking axis the station will be in the predicted position everything’s looking good as we transition from one docking axis to the other now you may have noticed uh we’ve been showing a lot of views live views from the various control rooms uh and the flight control teams that are supporting today’s maneuver from the ground uh it’s expected that we’ll have a gap in some live video from the international space station during the port relocation now this is all due to the equipment locations and orbital mechanics of some of the communication equipment that’s on board the international space station one of our cronus flight controllers who manages cameras and communications with the space station chris white recently gave a good explainer on twitter as to why we are seeing just the views here and not the views from space now that live video comes down thanks to our ku band which is a high data rate communications from space to ground the antenna that provides that is uh points to one of the tdrs or tracking and data relay satellites which then release the signal back to the ground that antenna happens to be located on the top part of the section stop top part of the station where it could most effectively point uh at the different tdrs satellites which orbit about 22 a little bit more than 22 000 miles above the earth to give you some perspective the international space station is currently orbiting at roughly 250 miles now those satellites provide communication to multiple spacecraft and satellites including familiar ones like the space station dragon hubble space telescope now for today’s operation the tdrs were in range of would be behind the dragon during his approach so that means any signal that the antenna would send would reflect off of dragon which could potentially damage the antennas tracking sensors so to prevent this the cronus flight controller here in mission control houston activates what’s called a mask which basically prevents the antenna from pointing at a specific area of the sky any uh spacecraft that approaches zenith or the space-facing side port of harmony which is part of the maneuver today has large area off limits to the antenna for the antenna to point and if the antenna can’t point at the closest tdrs satellite then we can’t send the video signal here’s a view from the a cargo dragon undocking from this position you can see the car that uh that dish that you see there on the right is a space degree you may be able to see some live views as dragon makes its final approach from the 20 meter hold point at waypoint 2 down to the docking axis but otherwise we’re gonna play it safe and mask off the area as dragon makes this position right in between the dish there that you see on the right the space to ground antenna and the tracking and data rios relay satellites in geosynchronous orbit more than 22 000 miles from earth for those just joining crew dragon has undocked from the international space station and is currently making its way to the midpoint in these in this relocation maneuver it will stop and hold once it’s 60 meters directly above the node 2 zenith port and prepare for final approach which is just 20 meters away from station once it’s there the crew dragon will hold one final time for teams on the ground and the astronauts aboard dragon to do a final check before docking there aren’t any strict requirements to complete docking during a day or night pass but there’s always the chance that this could hold uh excuse me this could hold this hold could continue until lighting conditions on the docking port are ideal once ready dragon will begin its final approach back to the space station and we’re just about one minute until dragon reaches that midpoint throughout this maneuver to um uh the new docking access this transition path the sta the dragon itself has been holding roughly 60 meters away from the station as it transitions from one docking port to the other as we near the midpoint that’ll be the halfway point until we reach the new docking access in the meantime as we make this transition please send in some questions using the ask nasa we’ll do our best to answer them here as we continue to cover the port relocation maneuver and crew 2 making their way to the new docking axis dragon spacex on the big loop midpoint has been reached and you heard that confirmation the crew dragon endeavor making a successful maneuver from the original docking access after undocking on time 5 45 am central time moving out to about 95 meters then back to 60 meters initiating the transition maneuver and holding at 60 meters uh from the original docking axis to the midpoint now it’s uh from the mid now it’s making a transition from that midpoint to the new docking axis it’ll take uh just about another nine minutes in the meantime we’ll cover uh the crew that’s currently on board crew dragon endeavor first is uh commander uh dragon commander shane kimbrough it’ll be his or it is his uh third trip to space he was born in clean texas and raised in atlanta and was selected as an astronaut in 2004. kim bro is a retired us army colonel and holds degrees in aerospace engineering and operations research he first launched aboard the space shuttle endeavour on sts-126 then aboard a russian soyuz spacecraft for expedition 49 and 50. kimbrough is the spacecraft commander for the crew 2 flight and is a flight and it is a flight engineer for expedition 65 and 66 on station in addition to the usual complement of science and maintenance work for our astronauts he completed three space walks earlier this summer with thomas to install the first of this in a series of new solar arrays on the station bring his total spacewalk count to nine this mission marks pilot megan macarthur’s second trip to space but her first one to the space station she was born in honolulu but considers california her home state nasa selected macarthur as an astronaut in 2000 she holds degrees in aerospace engineering and oceanography macarthur served as mission specialists aboard space shuttle atlantis on sts-125 the final servicing mission of the hubble space telescope in 2009. she operated the shuttle’s robotic arm over the course of 12 days and 21 hours capturing the telescope and maneuvering crew members throughout the five space walks to upgrade hubble’s science instruments along with removal and replacement of other components to lengthen the telescope’s life macarthur is crew dragon endeavors pilot for the crew 2 mission and is serving as a flight engineer conducting science and maintenance for expedition 65 and 66 aboard the station mission specialist aki hoshide is currently on his third trip to space born in tokyo hoshide was selected as an astronaut in 1999 by the national space development agency of japan known today as japan aerospace exploration agency or jaxa hoshide earned degrees in aerospace engineering and mechanical engineering he flew on sts-124 aboard the space shuttle discovery to deliver and install japan’s science laboratory kibo he also flew aboard the russian soyuz on expeditions 32 and 33 for a 124 day visit to the international space station in 2014 he also served as commander of the 18th nasa extreme environment mission operation an underwater expedition at the national oceanic and atmospheric administration’s aquarius habitat off of florida’s key largo coast coast he now serves as the commander for the international space station for expedition 65 and as a mission specialist for the crew 2 flight crew 2 is mission specialist thomas pesquet’s second trip to space born in ruan france pesquet was selected by esa as an astronaut in 2009 he has a degree in spacecraft design and control and more than 2300 flight hours as a command commercial airline pilot pesquet first flew to space on the soyuz as a flight engineer for expeditions 50 and 51. in that time he worked on more than 50 experiments and performed two spacewalks to maintain the space station he has logged 197 days in space pesquet is the first european to fly in a crew dragon and the free to launch from america in more than a decade he’s currently a flight engineer for expedition 65 and will take over the role of station commander later this fall before returning to earth with the rest of the crew 2 astronauts on docking access and past the midway point uh we’re now in the final stretch of the uh transition from the midway point which is the halfway marker between the original docking access and the new one and dragon you see locking axis on the space facing side uh really pointing right out towards the space that’s where the international docking adapter 3 is located we’re in the final stretch and now starting to get some views from the international space station of crew drag and endeavor in the final stretch of this transition from the midway point to the new docking axis in the final moments here we’re getting some questions using the hashtag ask nasa please keep sending them in as we continue our coverage of crew dragons maneuver to a new port uh this first question comes in uh asking about how about the views that we’re seeing how come people in space station mission control room are able to maintain live views of the international space station but we can’t uh the answer is that the folks that you’re seeing here in mission control houston are looking at the same views that we are so now we are getting the views from the outside of the international space station using some of the external cameras you see here here’s a few a shot from the back of the room we’re now getting these views now these space to ground communications the reason we’re able to get these views is due to a communications antenna that’s located on the outside of the international space station pointing towards the tracking and data relay satellites now for a large portion of today’s maneuver some of those uh some of those shots are going to be mass the the communication path between the station which is 250 miles and the geosynchronous tracking and data relay satellites which are more than 22 000 miles from earth we mask off those areas to prevent any damage to the communication antennas as they’re sending high data rate uh radio frequency signals uh where dragon really is in between that communication path so we wouldn’t want the high data rate communication signals to bounce off of the dragon back to the antenna and uh and possibly affect some of the auto track sensors that are on the outside of the station so the views that you’re seeing are going to be periodic we may lose them as we make our way to the new docking access right now we’re in the home stretch getting some good views uh the cronus the uh mission controller here in mission control houston is over exposing the image of the dragon you see it sort of very brightly coming into our view now when the cronus overexposes the image and increases the aperture of the station’s cameras you can start to see some of the draco engine engines firing uh the different plumes uh you’ll see that coming out of dragon as it makes its transition that helps to stabilize uh the dragon as it makes its way from one docking axis to the other over exposing now you if you look carefully at your screen you can see the uh crew dragon capsule there firing its um some actuation thrusters there too aligned for this autonomous procedure dragon spacex on the big loop dragon has arrived at the 60 meter hold point on zenith and dragon is configured for docking confirm crew readiness for approach one never copies all crew is ready for a first one getting more live views from the international space station flight control room you heard confirmation that dragon has arrived at his new docking axis holding at 60 meters steady the approach one maneuver will it be executed here shortly and will move dragon in from the 60 meter hold point down to waypoint to a 20 meter hold point uh from there it’ll hold once again and teams in both mission control houston hawthorne will conduct a go no-go readiness poll and make sure that we are good to proceed from waypoint 2 down to docking with the new port and dragon spacex on the big loop ground is now go to continue approach and we will be to approach to waypoint two we are ready for the resume and the station houston on the big loop approach resume to waypoint approach is resuming to wait point two monitor per step two and one decimal one zero four crew dragon approach and retreat monitoring good work thanks as we mentioned before the port relocation maneuvers are completely autonomous when it comes to the dragon spacecraft although the all four crew members are suited up and strapped into their seats within the crew dragon capsule they are not commanding the vehicle from inside that all those commands are being sent from ground and the crew inside the capsule is monitoring as we heard call out there on the loops and we heard that confirmation dragon is moving from the 60 meter hold point now at about 46 meters and closing into the 20 meter hold again that way.2 will be a hold command teams will conduct a readiness review making sure everything is good before proceeding in for a docking in the meantime we’re getting live views from the international space station we’ve described the masking that’s required as dragon uh now is really in between the uh space to ground antenna and the tracking and data relay satellites so our views uh of the docking maneuver will be pretty sparse throughout the remainder of today’s coverage we may get a little sneak peek of dragon actually making uh contact with the new international docking adapter now 34 meters and closing in the meantime keep sending in your questions using the hashtag ask nasa we’ll try to answer as many as we can as we continue our coverage today uh this next one is about why we are conducting the maneuver uh why can a boeing starliner not dock in place where endeavour was originally located so why is this maneuver required well boeing’s cst 100 starliner flight software has been certified for docking to the forward port on harmony for its flight test to the international space station the forward port offers a less complex approach and presents better lighting conditions without the earthen view of navigation and tracking sensors utilizing that forward port on these initial test flights puts the safety of the crew and the two vehicles first starliner will be able to dock to both ports and have the ability to perform port relocation maneuvers by the starliner one mission this is similar to the approach taken during the first dockings of crew dragon during its first test flights to the hey megan just station your awareness we are waiting on ground station on the big loop our procedure review complete and uh the iss crew is ready for docking copy and we will be anticipating holding at waypoint 2 momentarily for copies we will expect to hold at waypoint 2. as you’re getting live views of the international space station flight control room we have confirmation that the crew dragon is holding at waypoint 2 just 20 meters away from the international space station this is the final hold point before it makes its way uh from this final hole point 20 meters away to contact and capture with its new docking port as we wait here and the teams assess uh the go readiness for proceeding in with a docking we already heard that go from the crew keep sending in your questions using the hashtag ask nasa uh this next one comes from alex uh who’s asking why does the crew dragon uh crew need to be on board uh during it the dock itself a good question why not just let the dragon autonomously move from one port to the other the idea is that in the event of a contingency if anything were to happen during the port relocation maneuver say it couldn’t undock or if there was anything that were to happen to the crew dragon itself that the four members of the crew have the available seats in the uh we’ll call it an escape pod that gets them down to earth at all times on them or the international space station there needs to be enough seats in the visiting vehicles to provide transportation a safe transportation from the international space station back down to earth so if anything were to happen before the two for the crew dragon all four would have enough seats to return back to the earth safely so although unfortunately we don’t have video of crew dragon uh all four crew members like we mentioned before are suited up and buckled into their seats inside the crew dragon capsule during this port relocation maneuver they are now in the final half of this maneuver we’re going to be the final step will be the final approach which will take about four minutes we’ll hear a call out for chop which stands for crew hands-off point and this occurs when the spacecraft is about two meters away from the docking port and means that any aborts need to be initiated by dragon’s flight computer and after after that point rather than by the crew and that call will happen at about the two meter point uh it will just be a matter of seconds really from two meters until it makes contact and capture with the international space station that initial capture time will report out as a soft capture the soft capture ring itself will retract pulling the dragon in to begin a hard mating sequence with the international docking adapter that aligns the hooks very nicely and they’ll engage just like we saw at the beginning of today’s coverage all 12 hooks releasing six at a time we’ll see the opposite during the docking sequence these 12 hooks will engage to hard mate the crew dragon to the international docking adapter six at a time dragon spacex on the big loop ground is go for final approach and will be commanding resume shortly please confirm readiness for final approach and visors are down crew is go we can confirm that the docking light is on additionally additionally as a reminder once dragon is inside the crew hands off point retreat and breakout are no longer permitted and station houston on the big loop monitor per step three and four and one decimal one zero four crude dragon approach and retreat monitoring and work thanks and we’re getting views from the external cameras of the international space station you can see the forward end of the dragon right there that soft capture ring uh fully extended and the uh sequence for moving in from waypoint 2 to docking has begun we’re now inside uh 20 meters from the international space station this sequence as we move then we’ll take about four minutes until we get a contact and capture of the dragon bringing our four crew members inside dragon back inside the international space station some of the calls you heard uh during this approach uh we of course have mark van gaal inside the international space station monitoring the approach of course with the four crew members of the dragon itself inside uh watching the sequences here the big loop you’re hearing is the communications channel of the uh space to ground communications as well as drag in the ground so all the all the communications you’re hearing is being heard by uh the ground teams here in mission control houston as well as mission control in hawthorne and of course the crew inside dragon as well as inside the international space station we’re now 15 meters in closing love to see this view of the crew dragon approaching the space station autonomously driving itself if you recall from the previous version of uh crew excuse me in the previous version of dragon the cargo capsules we they docked to the station actually not by docking but by birthing which essentially required the robotic canada arm to grapple the spacecraft and bring it to the station manually so to see crew dragon this upgraded version flying on its own without any assistance and able to dock autonomously with the space station is a an awesome capability that’s just so great to see with our eyes here 10 meters copy 10 meters at 10 meters away from this vantage point you see the earth there in the lower left corner we’re now flying 262 statute miles over india great shot of the forward five meters great shot of the forward end of crew dragon there yeah located near the top of the forward draco station which of course is not being all the maneuvers are managed with the service section draco thrusters crew hands off point three meters in closing copy hands off no 262 miles over western china that talking time 6 35 a.m central time 11 35 gmt double copy upcoming the teams will command crew dragon to begin the hard capture by commanding the hooks again they will operate in two sets of six so a total of twelve hooks uh will hook in i should go as long as it will have confirmation of hard mate complete whatever did they foreign three meters in closing nicely copy hands off looking hey uh placed for transportation to stations and with that we have a confirmed contact and soft capture dragon and station we’re flying 262 miles over westbrook to return home and allow the heat shield at the bottom of the pressurized section to be exposed and allow the crew dragon to splash down safely in the atlantic ocean dragon spacex rain retraction is complete docking sequence is holding for mcs reconfiguration never happy with that side view of crew dragon we have a great shot of the service section draco thrusters that i mentioned earlier there the the portholes there on the side of crew dragon uh that is where the thrust comes out from the draco thrusters and those are the service section thrusters that we utilized for for relocation maneuvering station are never on the big loop mcs is configured proceeding with hook driving mission copies with the soft capture ring retracted before the hard mate sequence can begin again there are 12 hooks that are going to secure crew dragon endeavor to the international docking adapter uh teams here in mission control houston configured the international space station to be on control moment gyro attitude control now that it switched over to control moment gyros they can begin the hard docking sequence with the driving of the first set of hooks they’re going to drive six at a time to make 12 hooks total securing the dragon endeavor to the international docking adapter and with that we have confirmation that the first set of hosts are driving [Music] the foreign you director as the first set of hooks continued to drive there are again two sets of hooks six each to hard mate the crew dragon endeavor to the international space station a recap of today’s activities early this morning the crew woke up at about one o’clock am central time getting ready for their day uh eating some food brushing their teeth and getting suited up to get ready to go inside dragon and begin today’s port relocation maneuver after they ingrassed the dragon and closed the hatches dragonside and uh international space station uh nasa astronaut mark van haye closed the hatch on the station side the a pass hatch after fixing a docking target the crew was suited up performed leak checks in their spacex spacesuits and got ready for an undocking of the original docking ports where crew dragon endeavor was just about an hour ago the uh crew dragon endeavour and the four crew members inside shane kimbrough megan mcarthur uh tama pesquet and aki hoshide undocked at 5 45 a.m central time about an hour ago and made the transition to the new docking port making contact and capture with the board that you’re seeing here the zenith or space facing port at 5 35 a.m central time completing the 50 minute maneuver from the original docking port to its new home making uh room on the forward harmony part uh for the uh uh boeing cst 100 starliner to dock here uh in uh next week uh july 30th is when it’s set to launch making contact and capture with the international space station set 24 hours later at this point in time the first set of hooks have closed and the second set are driving again there are 12 in total and they operate in two sets of six and we’re waiting for confirmation of the closure of the second set of hooks endeavor spacex on the big loop hard capture is complete you are go to raise your visors and with that we have confirmation that the second set of hooks has finished driving so all 12 hooks now securing the crew dragon endeavor to the international space station teams here will now undergo a series of steps to pressurize the vestibule in between the dragon hatch and the station hatch just like we saw earlier during today’s coverage with the depressurization of the original docking port uh we’ll see everything in reverse to allow the pressurization to equalize making sure everything is good before opening up the hatch and that’s inside dragging back inside macarthur european space agency astronauts and japan aerospace exploration agency astronaut they have re-docked with the international space station boeing’s cst starliner this will be boeing’s second test flight of starliner without crew as they seek to put the spacecraft through all the phases
