Thursday ’s launch attemptfor the Orion paradigm spacecraft wasdelayed by gusting wind and scrubbed by a viscous valve . The 4.5 hour trial run flight is currently on time and underway , with splashdown schedule for off the west coast of Baja California around 8:26 am PST .

Hunter is NASA ’s new prototype vehiclefor carrying humans into thick outer space . While this first test flight is uncrewed , later missions are designate to bring humans to asteroid in lunar cranial orbit , or even on to Mars . ForExploration Flight Test – 1 , a Delta IV Heavy rocket manufactured by United Launch Alliance will carry Orion out into quad and institutionalize it on an egg-shaped orbital cavity out through the Van Allen actinotherapy belts . The starship will chuck everything but the bunch module during reentry , splashing down off the west coast of Baja California .

The launch windowpane for Exploration Flight Test – 1 starts at 7:05 am EST , extending 2 hour , 39 minutes until 9:44 am .
The chief operating officer and Eruca vesicaria sativa builder for United Launch Alliance , Dan Collins , has a very personal relationship with his Delta IV Heavy . In discourse the Thursday launch attempt chaparral , he said :
“ Our squad knows our rocket very , very well . The team was perfectly on their game , listening to everything the rocket was recount us , and it finally assure us it was n’t ready to go . And so we ’ll go ensure we ’ve got a happy rocket and as soon as we do that , we ’re going to get back to the pad and send Orion off to a very , very successful trial run flight . ”
Here ’s hoping we have a very happy Eruca sativa !

12:58 am PST ( 2:58 am EST ): Launch conditions are40 % go for launch , with a luck of rain or warm steer from a storm system moving up from the south of the launching nerve center . The elementary headache as of thecurrent forecastare rain in the rocket launch route ( Flight Through Precipitation ) , cumulus clouds that may hold out high enough to be at freeze temperatures ( Cumulus Clouds ) , and tip at the lauch situation ( Liftoff wind instrument ) . The launch team is affirmative that the winds will be derive from a different centering this morning than yesterday , slicing around the thin profile of the rockets instead of bang up point - on into the triple - wide piston chamber .

After preparing the booster cylinder , the rocket crew started slowly - load cryogenically - chilled liquid H and atomic number 8 into their tank . Thehydrogen is adulterate first , and will be kept at -252 ° C ( -423 ° F ) . The liquid oxygen will be load later , keep at a heater - but - still cold-blooded -183 ° C ( -297 ° F ) .
The Orion spacecraft has dawning launch windows appropriate on Thursday through Saturday of this hebdomad , but the storage tank only hold enough cryogenically cool down fuel to try launching a Heavy on any two of three days . With the Delta IV heavy rocket fuelling started , NASA is attached to the launch attempt . If the launch is scour again today , they will be unable to try during the Saturday window . If that happens , Orion has no more sentence reserved on the range , and will demand to puzzle out with the Space Complex for a Sunday launch window . Any later than that , and Orion starts bunk into logistical fight with other pre - scheduled launching .

2:05 am PST ( 5:05 am EST ): Weather is currently violating launch status standard withboth rain and cumulus cloudsas a tempest rolls in . This was expect , and with a mo of hazard will clear up before the launch window open at 7:05 am EST .
2:23 am PST ( 5:23 am EST ): The rocket is in full fuelled for today ’s launch attempt . The chilled fuel will evaporate off throughout the launch preparations and countdown , so a small drip will continuously be add until the final countdown . The fill and drainpipe valve used for this dribble - filling refusing to close in the final three minutes of the countdown were what scrubbed the launching effort on Thursday .
2:36 am PST ( 5:36 am EST ): As this is just the 8th launch ever of a Delta IV in Heavy conformation , it makes gumption that ULA would go all - out in snap this once - in - a - lifetime PR opportunity . But somehow , these rocket seem far more romantic , glamourous , and even soft for typical rocketry photography . This is aromantic skyrocket gallery .

2:40 am PST ( 5:40 am EST ): Rain has blockade at the inkpad . conditions conditions aregreen to gofor launching . The forecast remains at40 % for clean conditions once the launch windowpane opens .
2:47 am PST ( 5:47 am EST ): Launch window are slippery beast , the resolution of thecareful stage dancing of orbital kinetics and flight . While a window commence at 7:05 am , extending 2 hours and 39 minute of arc until 9:44 am sounds downright arbitrary , Orion ’s launch windowpane is influence by the indigence slip the ballistic capsule on its predetermined flight around the Earth while still splosh down in the Pacific Ocean with ample daylight for retrieval operation .
Other types of launches have very dissimilar requirements : theOrbiting Carbon Observatoryhad a launching windowpane just 30 moment long , leading to ascrub / reattemptto get in orbit . Spy satellitesare downright notorious for daytime launches .
The same dynamics impact how often a launching window can open for iterate attempt : windows for themost fuel - effective journeys to Marsopen up 23 months aside !

3:04 am PST ( 6:04 am Eastern Time ): NASA ’s bouncy insurance coverage has started ( rain cats and dogs above ! ) .
Mike Curie , the serene voice talking during most of the live flow .
MikeCurie has confirm that the viscous valves that stimulate the launch scrub on Thursday were because the fill and drain valve were sitting in extremely cold fluid atomic number 1 for 2.5 hours and started responding sluggishly . Once the armoured combat vehicle were drained and the valves warmed up , they functioned perfectly and required no hardware successor . To forfend a repeat job , Orion just involve to launch in the first place in the window . If it does happen again , engineers will supercharge pressure in the tanks , forcing the valve closed , then motorbike the valves repeatedly . This will hopefully loosen them up enough to function properly .

3:10 am PST ( 6:10 am EST ): A missive to Orion ’s roquette :
Dear Delta IV Heavy Eruca vesicaria sativa ,
Your safety checks seem good , and you look even better . Please , be happy , and give us a beautiful launch and kick off our weekend in fashion . I promise to be exceedingly impressed by your badassery when you casually light up yourself on fire with the pooled hydrogen that avoided getting burned off by the bat safety flare to the side of the launching pad .
In sleep - deprived delirium ,
a rocket - loving West Coaster .
3:16 am PST ( 6:16 am EST ): Launch coach have reported in that both the Orion ballistic capsule and the Delta IV roquette look good , with no technical issues being exercise at this time .
3:18 am PST ( 3:18 am EST ): Although winds are stronger today , they ’re coming from north-east alternatively of north . This is a more favorable direction , as the launching stipulation criterion can stomach up to 12 meters per second ( 23.5 knot ) hint from that centering . As the sun comes up and the launch pad warms up , rain is less likely but current of air speeds may increase .

3:30am PST ( 6:30 am EST ): The fluid atomic number 1 and O in the tanks is so inhuman that it is constantly evaporating . The vapor is mark by white water vapour at the tops of the tanks , a visible admonisher of why the armored combat vehicle want to be perpetually fill again at a lilliputian dribble during launch grooming .
To keep hydrogen from build up on the pad and fire a detonation risk , a hydrogen flare batch constantly burns to the side of the launch launchpad . This red flaming adds a bit of drama to the inking pad while doing a vital job , but it does n’t entirely burn off all the hydrogen . Some of it rest pool on the digs , but enough remains to set fire licking up the booster during ignition . While this looks totally terrifying if you do n’t expect it , it ’s a normal part of the Delta IV lighting .

3:36 am PST ( 6:36 am EST ): The weather is currently good to launch , and looks better for earlier in the launching windowpane . Winds are presently gusting up to 21 air mile , expected to increase to 22 knots at the start of the windowpane and possibly increasing to 23 knots by the end of the window . From this way , the Delta IV can tolerate nothingness up to 23.5 knots and still establish .

3:46 am PST ( 6:46 am EST ): The rocket is in a built - in hold at T-4 minute of arc left in the launch countdown . The countdown will not progress during this 15 minutes . trajectory teams will go through checklist , polling that all skyrocket , ballistic capsule , chain , and domiciliation experimental condition are good for launch . If all operate well , the hold will end at 7:01 am EST , starting the concluding countdown at T-4 minutes to the start of the launch window at 7:05 am .
3:48 am PST ( 6:48 am EST ): The swing arms involve to stay machine-accessible to the spacecraft and rocket until the last moment before launch , providing outside power to the space vehicle and drip - fuelling to the skyrocket . In the last few moments before launch , they swing away .

3:59 am PST ( 6:59 am EST ): Dear NASA Livefeed , UStream , Audio feed , and nomadic provender : I make love you and detest you so bad . If you put behind bars out on me again , I will find something really horrible for you to do .
4:01 am PST ( 7:01 am EST ): The Delta IV rocket is on national power . The fill and drain valves are closed . We are in the terminal countdown for launch . Go watch the feed ; we ’ll be back after !

Who worry if the Delta IV care to place itself on firing if it gets Hunter into orbit safely ?
L+0:00 ( 4:05 am PST/7:05 am EST ): WE HAVE LIFTOFF ! Go , Orion ! Go , Delta ! Go !

Missed the launching ? Here ’s a telecasting of it !
L+0:03 ( 4:08 am PST/7:08 am EST ): ULA ’s Steve Agid is calling the first five minutes of the flight of steps . The rocket now weighs half as much as it did at launch . The rocket is travelling faster than the speed of phone .
L+0:06 ( 4:11 am PST/7:11 am EST ): Houston has taken over launching commentary . Second stagecoach ignition was successful . Done protect the trade from the ambience , the inspection and repair module fairings have jettisoned , subdue weight for the rest of the escape . The launch abort scheme has jettison , with the jettison motor pull the abort system away from the spacecraft .
Jettisoning surplusage number of the Delta IV rocket .
Jettison of the military service module fairings .
L+0:11 ( 4:16 am PST/7:16 am EST ): Everything is going pure . Just arrant . Every undivided measure is lining up with the plan . Orion is about to pass on orbital insertion velocity , and is already sending rest home streaming video . unspoilt occupation , not - so - small space vehicle ! You ’re doing unbelievable !
L+0:16 ( 4:21 am PST/7:21 am EST ): The second stagecoach has cut off , but is not jettison . Now Orion will coast for 1 hour , 37 minute until 1:55:26 into the launching , when the second stage will come back online for a 4 bit , 45 2d tan .
Orion is doing barrel paradiddle to even out heating , making certain it ’s evenly baked on all sides . ( Technically , this is a “ Barbecue roll . ” Go on , moan . ) This maintain even thermic conditioning to help keep any component part from overheating . It will go on to roll until the second stagecoach reignite for the next burn at more or less 9:00 am EST .
L+0:33 ( 4:38 am PST/7:38 am EST ): The dependable bit of this long coast period is a prospect to catch up adding in launch exposure and telecasting . You know it ’s true .
L+0:44 ( 4:49 am PST/7:38 am EST ): One of three escape mental test television camera is providing a slimly degraded image . The photographic camera is give-up the ghost to be power - cycled to attempt to improve the image quality . The camera will be shut down when Orion travel through the Van Allen radiotherapy belt at L+2:05 and again at L+3:30 .
L+0:57 ( 5:02 am PST/8:02 am EST ): Exploration Flight Test – 1 is specifically project to incorporate all the bad parts of potential missions , not just put Orion through its paces but putting it through its paces as hard as potential .

I ’ve switched to listing time in terminal figure of how far into the test escape we are : L+hour : minute ( and sometimes : second ) . So far , these times are line up beautifully to the planned times outlined in this overview ofExploration Test Flight 1 .
https://gizmodo.com/heres-what-to-expect-during-the-first-orion-test-flight-1654607626
After the initial rush of excitement , the next major series of events will be at L+1:55 , at 9:00 am Eastern Time when the second point engine re - ignites to push Orion out of Low Earth Orbit and out further than any homo - rated ballistic capsule has gone since the Apollo missions . This will take Orion through the Van Allen radioactivity belt , testing out its shielding . It will reach maximum distance by L+3:05 before starting the journeying back to Earth .
If you need to prioritise just one more Erolia minutilla of Hunter - observance today , splashdown may be even more exciting than launch , with no chance of a do - over . The spacecraft will shed additional pieces at L+3:23 , begin change of direction at L+3:57 , and begin reentry at L+4:13 ( 8:18 am PST/11:18 am EST ) . We ’ll shortly lose touch with the spacecraft before parachute deploy and it splashes down at L+4:24 . With a bit of luck , a drone pipe currently lurk in the recuperation zona will give of footage of Orion coming home .
L+1:25 ( 5:30 am PST/8:30 am EST ): Conditions look good in the recovery area . We wo n’t know exactly where Orion will splashdown ( or precisely when ) until the second stage railway locomotive reignite for the final tan . While a lot is go on in terms of data collection for the tryout flight , not much is materialise that we can follow along at plate .
Lucky for us , that also means not much is pass off for ULA , so they ’ve had time toupload their launch photograph ! This was an unusual launch for ULA in that Lockheed Martin buy the Delta IV Heavy arugula outright .

L+1:47 ( 5:52 am PST/8:52 am EST ): Launch footage download , Orion ’s flight of stairs tv camera are back streaming view of the Earth .
View from one of Orion ’s on - plank cameras .
This integral launching is on bombardment power , as the service module that would normally deploy solar fender is not yet everlasting . Instead , the mental test trajectory is being done with a size - and - mickle appropriate replication for the module .
L+2:03 ( 6:08 am PST/9:08 am EST ): The second stage locomotive engine reignited decently on prison term , burning for 4 minutes , 40 second gear . Orion is now heading out on its 2nd , higher orbit , travel farther from distance than any human - rated ballistic capsule has gone since the moon mission . This is where thing get extremely interesting for datum collection : Will the radioactivity shielding be enough to protect the craft and its avionics from the Van Allen belt ? BIRD , the Battery - run Independent Radiation Detector will be monitor the craft from inside to find out ! The on - board flight of steps trial run cameras will close down as the craft passes through the irradiation belt .
Everything continues to go absolutely utterly , so the point where the commission team are n’t doing any trouble shoot or even talking much , just sit quietly watching and gather information .
If you need to take a break , get to work , have some food for thought , or otherwise prize yourself away from the live insurance coverage of Orion ’s first flight test , now is a really good time to do so . If you want to tune in for a historical moment , suss out back around L+3:05 ( 7:10 am PST/10:10 am EST ) when Orion hit the furthest point in its test flight and hopefully give us a courteous look at the Earth . thing will start get visually interesting again at L+3:23 ( 7:28 am PST/10:28 am EST ) as it lead off shedding non - substantive spacecraft bits in readying for re - accounting entry . You absolutely want to be back by L+4:13 ( 8:18 am PST/11:18 am EST ) when Orion begins reentry and splashdown . ( Those times may be off by a few minute of arc depending on how the unexpected extra 10 irregular of the final sunburn impacted the spacecraft ’s flight . )
L+2:54(6:49am PST/9:49am EST ): utterly no issue are being worked because Orion is a well-chosen , contented spacecraft . All of Orion ’s thrusters are tally out and work out perfectly .
Footage from the Ikhana remotely navigate aircraft flying in the recovery zona look document Orion ’s splashdown sure enough is pretty .
L+2:57 ( 7:02am PST/10:02am EST ): The burn information has now been integrated into splashdown forecasting , and once again the spacecraft is following the plan precisely . Orion is presently projected to experience a maximum of 8.2 chiliad of acceleration during slowing ( that ’s 8.2 time normal Earth gravitation ) , splosh down within 2.4 kilometers ( 1.3 marine mile ) of the pre - flight predicted object .
By comparison , a Soyuz space vehicle subject its crews to about 4 gibibyte during reentry .

L+3:07 ( 7:12 am PST/10:12 am EST ): Orion reach peak altitude at L+3:06 of 5,800.4 kilometre ( 3,604.2 knot ) . That ’s within 0.4 kilometre of the pre - flight prevision , carry on the trend of everything being on - clock time and on - prey during this test flight .

While high than any human - rated spacecraft has travel since Apollo 17 , this is still low compare to where our robots go on a regular basis . Geostationary artificial satellite are 6 time higher up than Orion ’s maximal altitude !
The on - board global locating system is working even intimately than omen , rendering this infographic insufficiently boastful :
L+3:23 ( 7:28 am PST/10:28 am EST ): The Orion crew mental faculty has slough the service module . It is now independent for the first sentence , steering with its thrusters . It will want to reorientate in preparation for reentry .
NASA just released more launch telecasting , far more up close and personal than a man could stomach . This is footage from the umbilical support tower !
L+3:33 ( 7:38 am PST/10:39 am EST ): Orion ’s heat shield has a pair of intentional fault : two small holes drill into the tiles to simulate micrometeoroid equipment casualty . It ’ll be interesting to see how it do when reentry starts ! ( Hunter is estimated to score the atmosphere starting at L+4:11 . )
L+3:55 ( 8:00 am PST/10:00 am EST ): Orion safely transit back through the Van Allen radiation belt back towards Earth . It also fired a quick ascent sunburn to line up its angle of flack for entering interface with the atmosphere , finessing its trajectory for an on - target splashdown .
L+4:13 ( 8:18 am PST/11:18 am EST ): As Orion hit the reentry port , superheated plasma will briefly reduce off contact with the spacecraft . Within two moment , it will hit a peak temperature of an approximate 2,200 ° C . Minutes later , protective coverings on the forward bay will jettison to expose parachutes .
Atmospheric breaking has slacken Orion from over 32,000 kilometer per hr ( 20,000 miles per hour ) to subsonic speeds .
L+04:19 ( 8:27 am PST/11:27 am EST ) The protective cover on the forward bay jettison , uncover the parachutes . The Forward Bay Cover jettisons through a combination of firework , thrusters , and drag from three chute attached right away to the cover . The parachutes will slow up it down for splashdown in the ocean .

The parachute are reefed — open up slowly — to limit both how much force is exert on them and how quickly they decelerate the work party capsule .
L+4:29 ( 8:29 am PST/11:29 am EST ) Orion is safely splashed down ! The craft splashed down upright ; three of the five airbags inflated to keep it that direction . Although this is n’t significant now , keeping the crew module befittingly oriented will be in the time to come when the spacecraft carries human crews .
A zodiac en path to recover the ejection seat [ left ] . Hunter bobbing upright in the Pacific Ocean [ right ] .
Hunter will be left powered on after splashdown to allow Lockheed Martin to gather more information on its thermal characteristics .
The test trajectory is now over , but recovery operations are just start . Orion is in Stable 1 : it ’s bodge upright in the Pacific Ocean . A salmagundi of craft are converge on it , and are confirming that it ’s not leak out anything smutty before they start hauling it in close for eventual securing in the USS Anchorage . Once in the well deck , Orion will be transported to San Diego .
It appears that the airplane pilot and drogue parachutes were lose , but two of the three principal parachute were recover . The panels were also mislay . This was bear : no data was lose along with the accessories . The recovered parachutes will be analyse for how they performed during the descent .
9:01 am PST/12:01pm EST : Orion ’s cooling arrangement are working absolutely , and the craft is air - tight . The recovery boats are all gathered around the craft , wait up - wind for the next leg in retrieval . In the next few hours , divers will check out the weewee around Orion and sweetener on anchor lines .
Lockheed was approved for an extended power test to see how Orion behaves in strange conditions . When the test is done in just over twenty minute , they will power Orion down .
Recovery crews waiting up - wind of the spacecraft .
After that , the US Navy will step up recovery procedure to haul the module into the inundated well deck of the USS Anchorage within the next few minute . From there , every mo and bolt of this craft will be examined , analyzed , and pull apart to ascertain precisely how it performed beyond “ dead . ”
This entire commission has been dead perfect every step of the way . It ’s a shame NASA ’s budget is so lowly they wo n’t be able to accomplish the next stage of the test program until 2018 !
