  • good afternoon from Hawthorne California it is June 25th just after 1 p.m.

  • Pacific time welcome to the webcast of the Falcon 9 mission carrying the second

  • flight of 10 iridium next satellites you are seeing a live view of Falcon 9

  • through the fog at Vandenberg as we prepare for launch in just under 15

  • minutes launch is currently scheduled for 20 hours 25 minutes 18 seconds

  • Universal Time or 1:25 18 Pacific Daylight Saving Time I'm John in

  • Sprecher Falcon 9 principle integration engineer and I'll be bringing you

  • coverage of the SpaceX launch of iridium next during the webcast this is our

  • second launch for our iridium customer our first launch for iridium was in

  • January of this year and as it would happen 48 hours ago that first age

  • successfully reflow to space carrying Bulgaria sat.1

  • today's launch is from Space Launch Complex 4 at Vandenberg Air Force Base

  • our West Coast launch site you can see as I said through the fog

  • we were hoping the fog would have lifted by now but a two-stage Falcon 9 vehicle

  • which is standing 70 meters tall taller than a 20-story building now the first

  • stage provides the initial force to get out of the majority of Earth's

  • atmosphere it carries the second stage of space back up to about a hundred

  • kilometers or 60 miles the first stage day will return to our drone ship named

  • just read the instructions now currently in the drone ship it's fairly windy

  • conditions are marginal I think Elon has been tweeting but we are still go for

  • landing the second stage on top of the first stage will take the satellites

  • from the edge of space and accelerate them to the orbital speeds of just over

  • seven and a half kilometers per second ten times faster than a speeding bullet

  • at the very top of the stack somewhat obscured by the gaseous oxygen plume is

  • a 17 foot diameter payload fairing within which are the tenth iridium

  • satellites next to the rocket you can see structure this is transporter

  • erector there are two major parts to the transporter erector if the bottom is the

  • launch mountain that's what the rocket sits upon and provides connections to

  • the first stage that's that gray area that you see around the engine nozzles

  • the white area is the strong back it's a vertical tower that provides connections

  • to the second stage and the spacecraft these connections are umbilicals they

  • carry power propellant gases electrical commands and telemetry now one reminder

  • for today's launch unlike our Cape launch is a Kennedy Space Center the

  • transporter director will recline to the flight position of 77 1/2 degrees before

  • liftoff now we're currently at t-minus eliminates at 25 seconds and counting we

  • are still on schedule for an on-time launch at just after 25 minutes after

  • the hour for the Falcon 9 team we're working no significant issues we began

  • loading propellants at t-minus 60 minutes fuel is currently loaded on the

  • second stage and fuel is pretty much loaded on the first

  • we have a little topping off that we have to do and that will finish at about

  • t-minus seven minutes liquid oxygen load is underway on both stages is we're

  • filling the voluminous first and second stages with that ultra cold liquid

  • oxygen now our mixed Adria activity coming up we'll be opening the pre

  • valves between the first stage tanks and the engines to chill in the pumps coming

  • at t-minus seven minutes now it's hard to see on the view but we are flying our

  • new titanium grip vents these are the dark gray fins you can see right in the

  • middle of your image these are slightly larger thermally more robust to be able

  • to survive the heat of reentry the first stage we'll see how they work today on a

  • spacecraft side the radiant team is already on internal power no significant

  • issues in work they are ready for launch the range we're launching out of

  • Vandenberg today that's the air force western range they're providing similar

  • support is the eastern range one issue which has cleared earlier this afternoon

  • there was a ship in proximity to the drone ship that ship is now out of the

  • keep out zone and we're good to land the first stage and finally the weather is

  • excellent other than the views on the pad where we have fog but we hope to get

  • some shots from the onboard cameras as we rise out of the fog layer which is so

  • typical of Vandenberg so right now at t-minus 9 minutes and 45 seconds

  • everything's going well

  • you

  • now today SpaceX is launching ten iridium next satellites this is our

  • second launch that we have on contract with iridium each of the ten satellites

  • has a mass of about 600 kilograms and when the solar rays on each satellite

  • are fully deployed they'll span almost over nine meters in

  • wingspan now in order to correctly position the satellites the SpaceX team

  • has to launch right on the second so as I mentioned we have a one-second window

  • today we do have a backup opportunity tomorrow should we need it now when the

  • Falcon 9 carries the Iridium satellites into the deployment orbit that will be a

  • target of 625 kilometers altitude once we're there Falcon 9 will send commands

  • to each satellite separation system the satellites will be released one at a

  • time and a spacing of every 100 seconds so the whole sequence will take us 15

  • minutes from start to finish now once deployed these 10 satellites

  • will augment the 10 that are already launched earlier this year the final

  • plan is for a constellation of 75 iridium next satellites which will allow

  • cross-linking between four other satellites allowing anybody on earth to

  • contact any other place on earth with a little bit more information on the

  • Iridium constellation system we had an interview with Matt - the CEO of iridium

  • will play that video for you now so we are in the iridium snack that's an

  • acronym for the satellite network operation center this is a Center in

  • Northern Virginia about 30 miles or so outside of Washington DC where for the

  • last 20 years we've been running our Iridium satellite constellation and

  • flying it in controlling the satellites and managing it and we're on launch day

  • we'll be anxiously awaiting the 10 new satellites that will come off the

  • dispenser about 100 minutes into the flight

  • and start phoning home and being managed by these control displays and the people

  • who man this Center so about an hour into the flight the satellites will

  • start coming off the dispenser about once every minute and a half until

  • they're all deployed each satellite will boot itself up if you will it will

  • deploy it solar panels that will find the Sun that will find the horizon and

  • start positioning itself and it will start using a secondary data channel to

  • try to communicate with this facility and this is an example of one of the

  • screens that the operator uses in the satellite control software this one's

  • actually setup for one of the new satellites this is set up for SP 125 by

  • C and you can see all the data points there's there's something like a hundred

  • thousand different parameters that can be controlled by operators here to make

  • adjustments to configure it differently and almost two thousand commands or so

  • that they can send back and forth to move the satellite to turn attributes

  • off and on and to control all aspects of the satellites I think people know of us

  • from sort of our services from 20 years ago the big satellite phones but don't

  • appreciate that satellite devices have gotten to be quite small in fact in many

  • cases they're built into a truck or a ship or into an airplane that you don't

  • even see them they're being put on shipping containers or oil and gas

  • pipelines and on on solar wind farms to bring information

  • back and make make businesses more efficient I think people know our

  • humanitarian side they know that we're the first on the scenes when really bad

  • things happen and we're critical when you're at the North Pole or in the ocean

  • but they don't appreciate probably that where we've over the years become part

  • of the communication fabric of the planet really and are integrated into so

  • many things with other technologies like cell phone technology to do many many

  • important things and with this launch today and with the new satellites that

  • we're putting in a space and the whole new network we're just excited about so

  • many more things that we can do it's almost like an an innovation engine that

  • really is unique that we can create so many new things from and it's created so

  • many things over the last 20 years I can't even imagine the kinds of things

  • we're going to create over the next 20 t-minus five minutes and five seconds

  • and counting down still heading for an on-time launch currently on the Falcon

  • nine we have finished loading fuel on both the first and second stage liquid

  • oxygen is continuing to load that'll lasted to the last two to three minutes

  • the strong back right now is getting ready to begin moving away from the

  • rocket the clamp arms will open up and the strong back will recline to the

  • launch position of seventy seven and a half degrees currently the Iridium

  • satellite is on internal power working no issues they are ready to go the range

  • is also ready everything is clear for Falcon 9 launch to head downrange and

  • for the first stage to land and finally the weather upper altitude winds look

  • good we've just heard the call out the cradle arms coming open is the strong

  • back prepares to move away from the Falcon 9 as I say on the weather upper

  • altitude winds are good load conditions are good their ground level is good and

  • we just have the traditional Vandenberg fog but hopefully we'll get a view from

  • the Falcon 9 as we head into space so currently we're coming up t-minus three

  • minutes in 50 seconds and counting everything continues to go on time we're

  • going to listen in to the last minutes of the count along with you we'll be

  • back during the plus count to explain events as they happen on our way to

  • two plus 53 seconds into flight we've just heard the call-outs that engines

  • are nominal we've also got good status on the avionics system we're coming up

  • on maximum dynamic pressure

  • t plus 1 minute 30 seconds into flight Maryland engines continue to perform

  • Romilly we've heard a call out of em that D engine chill has begun that

  • indicates that propellants now are being fed to the front of the turbopump on the

  • upper stage engine to chill it as we get ready to light the upper stage engine in

  • just about 45 seconds we're coming up on several major activities all at once

  • at about t plus 2 minutes and 24 seconds we should have cut off of the nine first

  • stage engines stage separation ignition to the upper stage engine and right

  • afterwards re-ignition of three first stage engines for boost back burn let's

  • listen and watch together

  • Steve simmer

  • aha

  • coming up on t plus three minutes stage separation recognition successful the

  • first stage booster n-- is underway we're coming up on fairing separation

  • now around the ten iridium satellites

  • verax appreciated for three minutes and 23 seconds in the flight you can hear

  • the applause at SpaceX smaller crowd many of our folks drove up actually to

  • watch the launch from Vandenberg just about 180 miles up the road from us

  • first stage grid fins are deploying you can see the new dark gray titanium grid

  • fins they deploy a little more slowly than the old lighter weight aluminum

  • fins second stage engine burn continues to look nominal chamber pressure is good

  • trajectory looks good for the second stage

  • stick to football for Solano

  • four minutes into fight you can see the grid fins are fully deployed we're

  • listening for when the drone ship has what they call a OS acquisition of

  • signal that will indicate the telemetry from the first stage is being received

  • by the drone ship the drone ship does not send commands to the first stage

  • employ four and a half minutes into flight the upper stage engine continues

  • to perform nominal each one at stage two power it's a tree to pay double

  • d-plus five minutes into the flight second-stage continues to perform well

  • carrying ten iridium satellites to a parking orbit the next major event is

  • entry burn we will light three merlin 1d engines on the first stage that will

  • slow us down for entry through the atmosphere it's a fairly long burn

  • should be coming up in about 30 seconds

  • six minutes into flight you can see the entry burn is underway on the Falcon

  • nine first stage bringing it back to the drone ship titled just read the

  • instructions awaiting it in the Pacific Ocean

  • do you own a entry burn is complete the next burn will be the landing burn so

  • right now we're coming up on seven minutes it's actually six minutes and 40

  • seconds into flight Stage one is headed back to the drum ship in the Pacific

  • Ocean second stage continues to head south

  • towards Antarctica as we head for a parking orbit which is expected shortly

  • after tail lesson approaches ALS on the drone ship means acquisition of signal

  • the drone ship now receiving telemetry from the Falcon 9 first stage is a

  • reminder weather conditions are borderline out at the drone ship we'll

  • hopefully see a landing coming up here shortly

  • lining burn is underway

  • which can follow through you can tell by the cheering in the

  • background first days flight 38 has landed on just read the instructions our

  • drone ship in the Pacific Ocean landing at about two plus seven minutes and 47

  • seconds right on time meanwhile the second stage

  • engine at 8 minutes and 13 seconds into flight continues to perform well we've

  • got less than one minute before we go into our low-earth parking orbit

  • Stage two aft SSA

  • we have Seco confirmation of second-stage engine

  • shutdown about nine minutes and 14 seconds into flight waiting to hear from

  • the orbit and you heard the call-out GNC confirms a good insertion orbit so the

  • first phase of today's flight is now complete first stage has returned to the

  • drone ship second stage is in the desired parking orbit we're now entering

  • a Coast phase Falcon 9 second stage with the 10 iridium satellites still on top

  • of it mounted to a SpaceX dispenser are heading south loop underneath the South

  • Pole of the earth passing over Antarctica come up over Africa and so we

  • will have spacecraft deployments coming up in about 51 minutes at about 2 + 51

  • minutes into flight actually 52 minutes into flight so we're going to do right

  • now there's a bit of a long pause we've got about another 40 minutes

  • before we get into the next major phase so we're going to leave you with the

  • animation we'll be back on the webcast at t plus 50 minutes with live

  • commentary that will have already come back to the second burn of the upper

  • stage engine followed by a short pause and then the deployment of 10 iridium

  • next satellites so with that we'll see you back here at about t + 50 minutes

  • you

  • you

  • you

  • you

  • you

  • you

  • HP anyway

  • hey what

  • this is one of the largest commercial satellite system being built today it's

  • still an incredible feat of Engineering that one company can't do alone it's an

  • opportunity of a lifetime to be on programming the size and
