美國太空總署發射無人駕駛天鵝座XL太空船

我們會聽到強迫臺電的呼叫 我們也會聽到強迫臺電的呼叫 強迫臺電是你旁邊的 大型輪胎結構 它在基礎上緊扣 並與發射桿在最初階段下接觸 首先我們會看到 第二階段的插槽 然後強迫臺電會開始轉移 慢慢地離開飛彈 它將達到T-3分鐘 T-3分鐘40秒 強迫臺電在發射前 扮演重要的角色 它將強迫臺電 轉移到插槽上 並向上提起 並在發射最後一秒 它提供燃料、電力、 電信和指令連接 在基礎系統和飛彈之間 我們會繼續查看 幾個更多燃料的階段 包括兩分鐘前的 強迫臺電 在飛行前,我們會確保 我們終於可以 在飛行前 插槽將準備移動 我們有20秒 從第二階段 插槽開始開啟 開始開啟 它是重要的 因為它可以能夠 穩定第二階段 在激活燃料 我們現在有不錯的視野 And so soon we should start to see those arms opening up It'll take about 15 seconds in total They're also useful because they prevent movement in high winds And once they are fully open Which is going to be soon Then the rocket will be fully free at the top Now it looks like those arms are fully open now And we should expect the strong back To start leaning back away from the rocket Giving it room for a liftoff Okay Almost complete There it goes Now at this point Both stages are nearly fully loaded With about a million pounds of propellant The first stage will be complete At around T minus 3 minutes Followed by the second stage Which is expected to wrap up Liquid oxygen loading At about T minus 2 minutes Stage 1 LOX load is complete The liquid oxygen loading for the first stage Has just completed Finalizing propellant loading for the booster The tanks are pressurized using helium And that helium is chilled too So it stays compatible with the cryogenic plumbing During flight that pressurization Helps force propellant into the engines As the tanks empty And then at T minus 60 seconds Falcon 9 will enter startup At that point The rocket's onboard flight computers will take over From there on out The countdown becomes fully autonomous And we are hearing Standing by to hear that call out For stage 2 LOX load to be complete Stage 2 LOX load is complete Prop load for the upper And right on time That liquid oxygen for the second stage Is now fully loaded Completing prop load for the upper stage We may also hear a call That Dragon's flight computer is in auto idle You may notice the white clouds Venting from around the rocket That isn't smoke That's actually condensation And is expected As the liquid oxygen warms Slightly inside the tanks Some of it boils off And that gas is That gas is now being vented To help manage the pressure When the vented oxygen hits the warm And humid outside air It instantly condenses into clouds Which you are getting visuals of On your screen now As of now the payload remains healthy And the rocket is tracking no issues Weather is green for Falcon 9 is in startup Good call out there Weather is green for a scheduled lift off At 6.11 p.m. Eastern Time And we are heading into the final moments Before launch Launch director go for launch At this point The autonomous flight computers Have taken over the launch countdown And stages 1 and 2 Are pressurizing before launch Everything looking good ahead of lift off T minus 15 seconds T minus 10 9 8 7 6 5 4 3 2 1 Engine full power And lift off Go Falcon Go Cygnus And lift off Falcon 9 and Cygnus take flight M1D chamber pressure nominal The SS William McCool is en route To the International Space Station Vehicle pitching down range As all nine Merlin engines have lit We are currently throttling down To prepare for max Q Which is the point in the mission profile Where the vehicle experiences The greatest amount of aerodynamic pressure Balance telemetry nominal On ascent Max Q is reached When the air density of the atmosphere Decreases faster Than the increasing speed of the rocket So look out for that call out Which we're expecting to hear short of Falcon 9 is supersonic Max Q And there's that call out for max Q Now coming up next are several events That are going to happen in rapid succession First is main engine cut off Stage separation Stage 1 flip Second engine start Boost back burn start And then fairing separation Main engine cut off or MECO Is where all nine M1D engines Stage 2 engine short On the Falcon 9 first stage Are shut down This is followed by separation Of the first and second stages Stage 1 flip Is when the booster uses Its nitrogen gas thrusters To flip the booster around And a few seconds later The Merlin vacuum engine On the second stage Will ignite to boost Cygnus To low earth orbit And that is also called out As second engine start 1 Or SES 1 After that Falcon 9's first stage Will ignite again To orient itself to head back to land And shortly thereafter The two fairing halves Will separate And expose the spacecraft To the vacuum of space And we should be hearing The first of those call outs In about 10 seconds from now Stage separation confirmed Fairing separation confirmed And there we heard the call outs For all of those events Which again were MECO Stage separation Stage 1 flip SES 1 Boost back burn start And fairing separation And coming up shortly We should hear a call out For completion of the boost back burn On the Falcon 9 first stage This burn which will last In total about 50 seconds Is the first of three burns That the booster needs to go through In order to make its way back To landing zone 2 At Cape Canaveral Space Force Station So there was the successful Boost back burn on the Falcon 9 first stage If you're just joining us You're watching live coverage Of Northrop Grumman's Commercial resupply services 23 mission to the space station We had an on-time liftoff At 6.11 p.m. Eastern Time From Space Launch Complex 40 At Cape Canaveral Space Force Station Now in order to make its way Back to land today The Falcon 9 first stage Has two more burns to execute Next up is the entry burn Where three of the Merlin engines Will reignite This helps to slow the stage down As it re-enters the upper part Of Earth's atmosphere And following the entry burn The booster will go through Its landing burn And this is a single engine burn That brings down the vehicle's speed Rapidly in order to land back on Earth And we should be hearing the call out For that entry burn In about two minutes from now During the entry burn Falcon 9 is decelerating By firing its Merlin engines But the vehicle is still moving really fast And this causes it to fly Through Merlin's exhaust gases Which are also known as the rocket's plume Which deposits a layer of soot On the vehicle surface And that's why our flight proven vehicles Look the way that they do The soot comes from the carbon-based fuel That Falcon 9 uses And with each flight The soot builds up a little bit more On the outside of the vehicle We are still more than a minute away From the beginning of the entry burn As you can see from the telemetry On the bottom of your screen The second stage is still picking up speed And is carrying Cygnus to orbit On the right side of the screen You can see that engine burn And on the left side You can see the first stage decelerating And making its way back to Earth Now you might have noticed On the left-hand side of your screen That Falcon 9 is equipped With those four hypersonic grid fins Which are positioned Near the top of the first stage Stage 1 is using nothing But those grid fins for steering As it returns to Earth They orient the rocket during re-entry And guide it during its descent Back down to Earth Reusability is the key To lowering the cost of space flight Enabling more investments In critical space infrastructure The Falcon 9 first stage That is supporting today's mission Is performing this entry burn For its fourth time And the payload fairings Are also flight proven With one half flying for its sixth time And the other half flying For its third time And we are moments away From the beginning of that entry burn You should see the graphics light up As the engines do On the bottom of your screen Stage 1 entry burn startup And there's the call out For the entry burn startup On the Falcon 9 first stage This burn is set to last About 20 seconds And again is slowing down the vehicle In preparation for its final burn And landing These are incredible Incredible clear views That we have today And we also just heard the call out For the entry burn shutdown Which is the completion Of the Falcon 9 first stage entry burn Coming up next Will be the first stage landing burn Which is going to start A little over a minute from now So soon we'll have that start Of the landing burn of the first stage This is the final burn Of the Falcon 9 booster Used to reduce the remaining speed Of the vehicle For a gentle and precise landing Check out those incredible views As it comes down Stage 1 FTS has saved Stage 1 transonic Stage 1 landing burn We just heard the call out For the landing burn start On the Falcon 9 first stage Again this is the final burn That this booster will see Before landing Stage 1 landing like deploy Stage 1 landing confirmed And that was another successful landing Of our Falcon 9 rocket Stage 2 has entered terminal guidance This is the fourth launch In landing for this first stage Stage 2 FTS has saved Coming up at around The eight and a half minute mark We should hear a call out For second engine cutoff one Or SECO one Which is when the MVEC engine On the second stage shuts down That'll conclude the roughly Six minute burn by this engine Needed to get Cygnus Into the proper orbit For eventually intercepting The International Space Station MVEC shutdown And there's that call out For the second stage We are now waiting for Confirmation of good orbit Nominal orbit insertion And there was a great call out there So at T plus eight minutes And 57 seconds into the mission And the second stage Has one last major task And that's commanding separation Of the Cygnus spacecraft In just a few minutes from now It's Northrop's tradition To name each Cygnus spacecraft After an individual Who has made significant contributions To human spaceflight The NG-23 Cygnus spacecraft Is named in honor of astronaut William or Willie McCool McCool was an astronaut and naval aviator Who piloted the 2003 Columbia spacecraft And lost his life during the mission His naval career included Over 2,800 flight hours And 24 aircraft And more than 400 career arrestments After being selected by NASA To become an astronaut In April of 1996 He reported to the Johnson Space Center In August of 1996 He completed two years of training And evaluation And was qualified For flight assessment as a pilot William McCool's spaceflight career Reached its pinnacle with his role As pilot of STS-107 Aboard the space shuttle Columbia The mission which launched On January 16th of 2003 Was dedicated to scientific research With the crew conducting Approximately 80 experiments Over a 16-day period Tragically, the mission ended abruptly On February 1st, 2003 When Columbia disintegrated During re-entry Just 16 minutes Before the scheduled landing Resulting in the loss of McCool And his fellow crew members In all, he logged 15 days 22 hours and 20 minutes in space In recognition of his exemplary Service and sacrifice McCool was posthumously awarded The Congressional Space Medal of Honor The NASA Space Flight Medal The NASA Distinguished Service Medal And the Defense Distinguished Service Medal William McCool's legacy endures Through his contributions to aviation And space exploration NG-23 is the first mission Using Northrop Grumman's Cygnus XL configuration Of its Cygnus line Of cargo delivery vehicles The cargo capacity of Cygnus XL Is 5,000 kilograms Which is 33% greater Than the previous version The expanded capacity of Cygnus XL Means more room for critical supplies And experiments in a single mission Improving the efficiency By reducing the number of launches Required for a given cargo mass For those of you just tuning in You are watching live coverage Of Northrop Grumman's Commercial Resupply Services 23 mission To the orbiting laboratory Following separation Cygnus will have a nearly 40-hour transit To the space station Where the station's Canadarm 2 will grapple Cygnus And the spacecraft will attach To the Unity module's Earth-facing port For cargo unloading Cygnus will be joining The CRS-33 SpaceX Dragon spacecraft Which docked with the space station On August 25th As well as the Crew-11 Dragon Which arrived on August 2nd Both Northrop Grumman and SpaceX Have a long history of supporting The International Space Station With cargo missions like today's SpaceX's first Commercial Resupply Services Or CRS mission, CRS-1 Launched in 2012 And made history By restoring America's capability To deliver and return cargo To the station The Cygnus spacecraft Has been visiting the ISS since 2013 And the first Cygnus CRS mission Or one launched in 2014 Cygnus has delivered More than 71,000 kilograms Of equipment, science experiments And supplies To sustain the ISS astronauts Under NASA's commercial Resupply services contracts The CRS partnership Has helped build a strong American commercial space industry That will soon take us to destinations Beyond low Earth orbit In fact, these missions Are providing critical learnings That will help us develop a human presence On the Moon and Mars Which will require a steady supply Of cargo missions In order to grow and to thrive Just as a quick correction It's actually a 60-hour transit To the station We're currently at T-plus 13 minutes and 37 seconds And we're expecting to hear The call out for payload deploy At around the T-plus 14 minute and 40 second mark As a reminder This is SpaceX's sixth mission Headed to the International Space Station So far this year Following NASA's CRS-33 And CRS-32 resupply missions NASA's Crew-10 and Crew-11 missions And Axiom Mission 4 On behalf of Axiom Space Following separation Cygnus will have that 60-hour transit To the space station Where the station's Canadarm2 Will grapple Cygnus And the spacecraft will attach To the Unity module's Earth-facing port For cargo unloading By the Expedition 73 crew We should be hearing That call out shortly For payload deployment Of the Cygnus spacecraft Cygnus separation confirmed And there you have it A successful spacecraft separation The Cygnus spacecraft Is now on its way To the International Space Station And as mentioned Is expected to arrive About 60 hours from now With successful separation That's gonna do it for me Here in Hawthorne Be sure to check out SpaceX.com slash launches For a schedule of our Upcoming missions And when you're there Check out our new departure board Featuring our upcoming launches With details such as The mission name Launch and landing site And liftoff time In the meantime Sandra Tell us what's next for Cygnus Thanks Tyler And welcome back into The International Space Station Flight control room Here at the Johnson Space Center In Houston Next up will be the deployment Of Cygnus' solar arrays Scheduled to begin at A mission elapsed time Of 2 hours and 29 minutes And should take about 45 minutes to be completed Once those arrays are deployed We will provide an update On the International Space Station Blog with the latest news But joining me now Is Ji Patel The manager of the Mission Integration And Operations Office And he's here today To discuss the launch Of Cygnus a little bit more So Ji how significant Was today's launch Of a larger Cygnus spacecraft And how valuable is this For continued Space station operations Hey thank you Sandra You know all of our missions Are critical But this particular mission Is even more so critical You know NG-22 was Scheduled to be launched in June And we had an issue With that spacecraft During a shipping incident And so we weren't able To get that mission launched And so the NG team Has done a phenomenal job Accelerating this mission Four months to be able to get This launch off today This is a different variant As you guys have highlighted It's the Cygnus XL Is what they call that It has 33% more capacity To launch cargo And it's extremely important There's a lot of Critical consumables Supplies, food, water, air That we need for station to maintain Habitability of crew And then also we've got Critical science That we also have on this mission And so we consider this Really important To be able to enhance And expand our capability To launch more cargo But in addition to that There's other functions That the Cygnus is going to serve It's certified for 200 days To be a first ISS And with that You can do some other operations Like what we call extend the lab So there's power locker Capability that's on the spacecraft And so we are able to power science Within the spacecraft While it is with ISS In addition to that We obviously like to dispose Or remove as much As we're bringing to station To maintain stowage And keep things habitable And so the 200 days helps us As the crew is accumulating trash For us to be able to stow that And then also the spacecraft Has a payload on it Post ISS That it's going to perform A demonstration It's called Palomino Which will demonstrate Some electric propulsion technologies And so all of this These capabilities Are really important To the overall mission Thank you Very insightful information Now if you would At this hour The crew is of course asleep On board the International Space Station But can you outline for us The upcoming activities For the crew on board As they prepare for Cygnus's Arrival early Wednesday Yes certainly So as you highlighted Xena Cardman and Johnny Kim Are going to be our robotic operators And so in prep for Arrival of Cygnus on Wednesday They are going to be conducting On board training To prepare for the robotic operations In addition to that On Tuesday The day prior to The capture and birthing of the vehicle They'll be preparing The Node 1 nadir patch Of the Unity module To be able to birth this capsule So for Xena and Johnny They'll be busy with those operations But then the rest of the crew Will be conducting critical science We've got ongoing time critical science Human research Biological science occurring And so the crew will remain busy The crew also has to maintain their health With exercise and other things And keep our systems up to operations And so there's routine Maintenance activities as well So and then in prep for 11,000 pounds of cargo arriving We have to conduct the operations With a certain choreography And so the teams The crew will be also looking At the choreography in advance So that they have understanding Of how we're going to stage the cargo And how we're going to Dispose of the trash That we need to remove from station Thank you very much We are certainly looking forward To Cygnus's arrival on Wednesday We really appreciate you Taking some time to join us today Thank you again Thank you And with that We will wrap up our launch coverage Of Northrop Grumman's 23rd Commercial Resupply Services mission Cygnus now on course to be captured At about 5.35 a.m. Central Or 6.35 a.m. Eastern On Wednesday morning Live coverage of rendezvous And capture will begin At 4 a.m. Central Or 5 a.m. Eastern Followed by coverage Of Cygnus's installation To the space station At 7 a.m. Central Or 8 a.m. Eastern In the meantime You can learn even more About this mission on the web At nasa.gov Slash commercial resupply Thanks so much for joining us today We'll see you back here Wednesday morning But for now this is Mission Control Houston
