CRS-13 Hosted Webcast

SpaceX is targeting launch of the Commercial Resupply Services 13 (CRS-13) mission from Launch Complex 40 at Cape Canaveral Air Force station in Florida for 7:35 a.m. PST, or 15:35 UTC, on Friday, Dec. 15, 2017
This mission marks the first time SpaceX is flying both a flight-proven Falcon 9 and a flight-proven Dragon spacecraft. Falcon 9’s first stage previously supported the CRS-11 mission in June 2017 and the Dragon spacecraft previously supported the CRS-6 mission in April 2015.
Dragon will deliver about 4,800 pounds of cargo and material to support science investigations aboard the space station. After about one month attached to the space station, Dragon will return with results of earlier experiments, splashing down in the Pacific Ocean off the coast of Baja California.
[music]. [music]. it's 10:20 a. m. eastern standard time . friday december 15th and you're looking . at a live shot of space launch complex . 40 where the spacex falcon 9 rocket is . about to launch a dragon mission to the . international space station hello and . welcome my name is kate theis and i'm a . certification engineer and i'm standing. here and our spacex headquarters in . hawthorne california today is spacex is . 13th cargo resupply mission to the . international space station or as you . may hear us call it the iss we're all . excited for this particular mission . because it's the first time that we're . flying both a flight proven first stage . and a flight proven dragon in other . words both of these vehicles have. already gone to space before this first . stage flew six months ago on crs 11 and . the dragon spacecraft flew on crs six in . april of . pretty cool stuff and we'll talk more . about this in just a moment also special . about today . it's our return to space launch complex . 40 we've bought we've made lots of cool . upgrades to the pad within the last year . this now gives us three operational . launch sites this one 39a both of which . are in florida and our california launch . site at vandenberg air force base let's . get started hi i'm michael hamersley and . materials engineer for our electronics. group and i'll be bringing you status . updates over the course of this mission . as kate mentioned today for the first . time we're flying to flight proven . vehicles the falcon 9 first stage which . previously flew in june of this year on . crs 11 and dragon spacecraft which . previously flew in april 2015 . on crs 8 ba falcon 9 and dragon were . designed with reef light in mind so the . vehicle hardware is built to support . multiple missions with minimal. refurbishment inman in between and for . this mission we've refurbished the . thermal protection system on dragons . exterior so that's why it looks. brand-new but you'll notice that the . falcon 9 first stage hasn't been . scrubbed down and you can still see the . suit from reentry the plan going forward . is to not wash or repaint any of the . first stage although from time to time . we may still scrub down or repaint parts. or all of it if dean benefit . we did that in this mission on the . interstage and the legs but for the most . part going forward the suit from reentry . will remain key takeaway for a falcon . and dragon at the moment is that we are . tracking no issues and we are on track . for an on-time launch just 13 minutes . from now a vehicle was raised by the . transport director late last night about . 12 hours ago and the go no-go poll was . conducted by launch control just over an. hour ago. propellant loading began shortly . thereafter currently the first stage and . the second stage are both full of rp1 . that kerosene propellant although we're . going to top up the the first stage at . about t-minus seven minutes just to make . sure it's totally full helium loading . began at t-minus 15 minutes and that's . what keeps the tank pressurized when . we're emptying it of propellant and . dragon is also getting ready and it . began its auto sequence at t-minus 35 . minutes that's when it coordinates . timing with falcon 9 and makes sure it's . systems are all healthy next big step . for dragon is coming up at t-minus eight . minutes when it's gonna move to internal. power to support its mission over the . two to three days that's gonna take to . dock with the iss currently the range is . ready to support and the weather is . looking absolutely gorgeous at the. moment no no major clouds to be worried . about this and some stratocumulus and . we've been launching balloons every 30 . minutes or so to be checking on the wind . speeds at various altitudes and there's . nothing looking unsafe for launch on. that front and we generally want those . winds to be under about 30 miles an hour . and make sure that there isn't too much . wind shear which is when the winds at. different altitudes are moving in . different directions overall still very . much a go for today's launch and we've . also made some upgrades to the patent . let's take a look . good morning my name is tompa dario i'm . a firmware engineer in the avionics. department here at spacex now as kate . and mike both said spacex is excited to . be back at space launch complex 40 or . slick 44 shortly spacex has spent the . past few years not only rebuilding slick . 40 but upgrading it to reinforced . structures improve its ground side. systems and replicate operations @lc 39a . which is our pad just a few miles to the . north it's important remembered that . this pad slick 40 was designed before . the first falcon one ever flew so this . rebuild includes lesson learned from . over a decade of building and operating . launch pads across the country some of . the important improvements that we've. made to the pad our new doghouses these . are the heavy metal shields to protect . the hold-downs . which are the large clamps to hold the. rocket down right until it leaves the . pad we've also installed a new flame . diverter system that can withstand much . longer engine firings which allows us to . do more static fire testing here instead . of shipping all of our reused cores back . to the greger texas upgrades to the . strong back which is the the tower next. to the rocket right here also included . new lift cylinders you can see those new . lift cylinders to the blue objects right . here these stronger lift cylinders allow . us to do one continuous lift process. from horizontal all the way to vertical . whereas before we were doing a two-step . process . we've also completely upgraded the lock . system on the pad this allows us to do . much faster densification and loading . that locks onto the rocket once it's . dense overall slick 40 has been upgraded . with additional redundancies to make it . safe and reliable as it's lc 39 a custom . to the north which is helpful as spacex . often sends employees and equipment. between the two pads so it's good to . have as much commonality as possible . between them together with pad 39a and . our west coast launch site in vandenberg . spacex now has three operational launch . pads more launch pads means more . launches which is the key to full and . rapid reusability. eleven years ago dragon was just a . design on a piece of paper today it's . the only vehicle flying that can deliver. a significant cargo both to and from the . international space station and it's . been an exciting ride to get us to where . we are in 2010 spacex became the first . private company to send a spacecraft to . orbit and return it to earth two years . later in 2012 dragon became the first . privately developed spacecraft to visit. the iss since then spacex has made a . total of 12 trips to the iss and were . under contract with nasa for a total of . 20 cargo resupply missions we're . currently flying cargo missions but . ultimately we will fly astronauts on . crew missions with our crews first crew. demo mission slated for next year . whether we're flying cargo or crew our . relationship with nasa is instrumental. to mission progress and success today's . mission marks the second time we've sent . a previously flown dragon to the iss the . first time a dragon was reused was on . crs 11 in april of this year . today's spacecraft was flown for the. first time on crs six in april of 2015 . that happens to be a mission that i . remember quite well as it was my first . rocket lunch as a spacex employee dragon . has become dragon has come a long way . from just a design on a piece of paper . and we chatted with dragon mission. management director jessica jensen to . find out more about that journey as well . as today's mission hi my name is jessica . jenson i'm the director of dragon . mission management here at spacex my . group is the main interface with nasa. for the cargo resupply services contract . what that means is responsible for two . main areas one is integrating the cargo . on the vehicle and two is meeting all of . nasa's safety requirements . in our partnership with nasa we have a . contract for cargo resupply services to . the space station the first contract was . set up for 12 missions we've recently . completed the 12 commission in september . of this year then we have eight more . follow-on missions for this contract and . then after that we jump onto the cirrus . 2 contract and that is where we're gonna . be using the crew dragon vehicle to . transport cargo to and from the space . station and the nice thing about that is . the crew dragon vehicle has additional . safety features beyond the vehicle we're . currently flying as well as a . significant increase in capability of . the type of research and science . payloads we can fly dragon carries two . types of cargo unpressurized cargo and . pressurized cargo and the pressurized . section of dragon we carry about 3,600 . pounds of cargo these are all items that . are gonna stay inside the iss primarily . for the astronauts that are there so . these are things such as food and coffee . but all kinds of science experiments as . well for the unpressurized cargo this is . international space station hardware or . payloads that are destined for use on . the outside of the space station almost . as important as carrying cargo to the . space station is safely bringing cargo . back home so the first thing we do when . a dragon gets home is unload all of the . cargo and turn that over to nasa after . that dragon is shipped to the spacex . facility in mcgregor texas in order to . reply a dragon capsule or a falcon 9 . first stage several analyses inspections . and tests have to be completed and so . it's one of the areas we do a . significant amount of inspection and . testing and we also do it in . coordination with nasa. nasa has been an amazing partner to . spacex we couldn't have done any of
