SpaceX is targeting a Falcon 9 launch of the PAZ satellite to low-Earth orbit on Thursday, February 22 from Space Launch Complex 4 East (SLC-4E) at Vandenberg Air Force Base, California. The instantaneous launch opportunity is at 6:17 a.m. PST, or 14:17 UTC. The satellite will be deployed approximately eleven minutes after launch.
Falcon 9’s first stage for the PAZ mission previously supported the FORMOSAT-5 mission from SLC-4E in August 2017. SpaceX will not attempt to recover Falcon 9’s first stage after launch.

[music]. on your screen is a live view of the . falcon 9 rocket as it prepares to launch . the news desaad path satellite into a . sun-synchronous polar orbit good morning . from spacex headquarters in hawthorne . california it is february 22nd just . after 6 o'clock a. m. pacific time i'm . tom per dario and i'm a firmware . engineer in the avionics department at . spacex right now it is a beautiful clear . morning at vandenberg air force base . where the falcon 9 rocket is about to . launch from space launch complex 4 which . is our west coast launch site throughout . this webcast i'll be bringing you live . coverage of the launch today from . liftoff all the way to the deployment of . the path satellite in addition to this . primary payload to spacex test . satellites will be flying as a secondary . payload on today's mission you may get a . glimpse of those when the path satellite . deploys but unfortunately we will lose . ground station coverage just after that . so our webcast coverage today will . conclude after the deployment of path . today is launched as from space launch. complex 4 at vandenberg air force base . which is spacex's west coast launch site . on the pad right now you can see the . two-stage falcon 9 vehicle standing 70 . metres tall which is taller than a . 20-story building the first stage which . makes up the bottom two-thirds of the . rocket provides the initial force to get . out of the majority of the earth's . atmosphere this will in fact be the . second flight of this first stage the . first having them on the formas at . mission in august of last year . through that liquid that condensation . smoke you may even be able to see . markings from that boosters first flight . however spacex is not planning on . recovering this first stage again today . we may hear call-outs in the launch nets . as the stage descends through the . atmosphere but no burns will be . performed and we won't be following its . progress on the webcast this is an . earlier iteration of the falcon 9 that's . already been used once and at this point . spacex is making room for our next . iteration of falcon 9 rocket which will . be qualified to be rapidly reused many . times on top of that first stage the . second stage makes up the rest of the . rocket on the pad this second stage . takes the satellite from the edge of . space and accelerates to orbital speeds . of just over seven and a half kilometers . per second which is ten times faster . than a speeding bullet . at the very top of falcon 9 is a 17 foot . diameter payload fairing. within which is the poth spacecraft and . the two spacex test satellites next to . the rocket you can see a white structure . to the right that is the transporter . erector or strong back unlike our east. coast launch pads this transporter . erector will recline to 77 and a half . degrees several minutes before liftoff. unlike our east coast launch pads where . it will where they those ones recline . immediately as the rocket leaves the pad. at t-minus seven minutes and 45 seconds . let's check out exactly how the rockets . doing right now this falcon 9 started . loading propellants at t-minus . minutes fuel is currently loaded on the . second stage and complete except for . topping off on that first stage liquid . oxygen or lox loading is in progress on . both stages and will continue all the . way down to t-minus three minutes the . next major activity is going to be . engine chill right now the liquid oxygen . that we load onto the rocket is . extremely cold and those merlin nine . merlin engines on stage one are at . ambient air temperature at vandenberg . air force base so if we release that . locks into the engines right now it . would immediately warm up and boil. causing bubbles and other unwanted . issues so in a few minutes we're gonna . be releasing just a small amount of . liquid oxygen into the engines to bring . them down to operating temperature this . is the process you'll hear on the nets . called an engine chill right now the . range has given us a green light for . launch right now if the satellite o's . can good as well everything's ready for . a launch at exactly team excuse me. 6:17 a. m. the weather is unbelievably . clear this is a rare day at vandenberg . air force base. sometimes the marine layer fog is so. thick you can't even see the rocket so . we have some beautiful shots might even . be able to see the rocket from los . angeles today we were tracking upper . level winds right now the upper level . winds that are about 95 percent of our . launch levels so we're still good to go . that we are monitoring them as we get . down to launch but ground level winds . and cloud rules are all looking great so . it looks like we're on track for a 6:17 . am wash in just about ten minus six . minutes . let's talk a little bit about today's . payload it is called puff which is the . spanish word for peace and it is a radar . satellite from spain's national earth . observation satellite program the path. mission is a dual-use mission funded by . the spanish ministry of defense and . managed by is de set a private spanish . communications company. pothe carries an x-band radar imaging . payload to collect views of the earth. for government and commercial customers . along with ship tracking and weather . sensors x-band radar allows the . satellite to image the earth day and. night regardless of weather conditions . on the surface this satellite will be . launched into a sun-synchronous polar . orbit meaning that its orbit stays in . the same plane with respect to the sun . as the earth rotates and revolves around . its own orbit this allows the path . satellite to image any given point on . the planet under the exact same lighting . conditions which is extremely useful for . imaging applications once operational . paths will be capable of generating . about 100 images a day covering an area . of more than 300 thousand kilometres . square and as we mentioned earlier there . are two spacex test satellites flying as . secondary payloads on this mission these . are meant to gather data in advance of . deploying and operating a satellite. constellation that will provide internet . service however even if these satellites . work as planned we still have . considerable technical work ahead of us . to design and deploy a low-earth orbit. satellite constellation this system if . successful would provide people in low . to moderate population densities around . the world with affordable high-speed . internet access including many that have . never had internet access before you may . catch a glimpse of these demo sets when . we deploy the path satellite but our . coverage and focus today will be on our . primary payload which is the pop . satellite. we are just after t-minus three minutes . away from liftoff so let's check in one. last time with the status of this rocket . fuel is fully loaded on both stages and. liquid oxygen is being topped off as we . speak right now the rocket is . pressurizing itself with helium gas sort . of like a soda can and derive some of . its strength from the pressure inside . the falcon 9 is pressurized with gaseous . helium and we press that up just before . releasing it from the strong back you . just saw those cradle arms from the. strong back released and right now the . transporter erector strong back is. reclined to its launch position at 77 . and 1/2 degrees right now the range is . still giving us a green light for launch . the weather is again looking fantastic . those upper-level winds are still . playing nice at 95% launch tolerances . remember this is an instantaneous launch . window so for any reason we decided not . to go today our backup window will be . tomorrow at 6:17 a. m. right now the . rocket is getting ready to launch so . let's listen any of those countdown nets . as we approach just under t-minus 2 . minutes. talking items on internal power . vehicles on self line . just loads of clothes down . the fpso spawns ready . organizers and startup. ld go for lunch. t-minus 30 . 20 . fifteen falcon is configured for play . they were positive nominal . our funky novel for those of you just . joining us you are watching the falcon 9 . as it ascends through the atmosphere . carrying the path satellite to a polar . sun-synchronous orbit. right now the rocket is approaching what . we call max-q this is the point at which . the aerodynamic forces in the rocket are. at the greatest. falcon 9 legally throttles itself down . as it passes through max q and then. throttles back up once we're through it . vehicle has reached maximum aerodynamic . pressure. we just passed through our maximum air . that i mean pressure max q that falcon 9 . rocket has no throttling back up to full . speed as it ascends through the . atmosphere. as that first stage ascends higher and . higher through the atmosphere the . ambient air pressure starts going. further and further down so you can see . those exhaust gases getting bigger and . bigger on your camera screen right now . and a few in about 20 seconds we're . gonna be passing through what we call . miko which is main engine cutoff that's . when that first stage is gonna complete . its burn shortly after that we'll have . stage separation and then second engine . start. ses one let's watch that happen now . let me go. [applause]. you just saw it on your screen that was . a good miko main engine cutoff a good . separation of that first stage and then . what appears to be a successful second . engine start one. stand by for fairing deploy and you just . saw it on your screen that was a . successful fairing deploy you can see . the fairing falling down below the. second stage in your screen right now . spacex will be attempting to recover . this fairing tod
