CRS-4 Launch

After four successful missions to the International Space Station, including three official resupply missions for NASA, SpaceX is set to launch its fourth official Commercial Resupply (CRS) mission to the orbiting lab. The SpaceX CRS-4 mission is targeting launch at 06:14 UTC Saturday, September 20 from Launch Complex 40 at the Cape Canaveral Air Force Station, Florida. If all goes as planned, Dragon will arrive at the station on Monday, September 22 for an expected four-week visit. Dragon is scheduled to return to Earth in mid-October for a parachute-assisted splashdown off the coast of southern California. Dragon is the only operational spacecraft capable of returning a significant amount of supplies back to Earth, including experiments.

Watching the liquid oxygen float in microgravity after SECO is amazing.

It's nice to see that someone in USA 🇺🇸 can still design, build and successfully launch a spacecraft.

Fun fact: this launch was the final use if the countdown clock at the press site that had been used all the way through Apollo 12 and the shuttle missions, replaced with a digital screened one.

I was up last night and felt this in my house. The stars were amazingly clear last night at about this time. I went outside and thought "op, there goes spacex again" while the rumble faded off. Looked it up, and surely the twitter page said they blasted off after a delay. I live a few hours north.

Two flights in two weeks, very nice. I guess you guys got that helium problem figured out.

SpaceX team you are making the WORLD proud! Thank you for being HUMANS! 
This was Jack Kennedy's dream, you are the REALITY! May GOD bless you and continue to give you endurance!
We can breath again!

The expanding exhaust in higher altitude looks more evenly distributed than ever before. I'm not sure whether this is something special or not but it looks great! Just look at this beauty: 16:42

I love watching these videos, thanks for making them available online!  The shots of inside the fuel tank(?) are especially cool.

[berlymahn]

Watching these awesome commercial launches makes my day.  Seriously.  Love your success.

Nice at 17:30 you can see the engine exhaust glow up just a few sec after the engine is turned on, imagine the heat of that engine

I am so happy to see private space flight in my lifetime. You guys are amazing! Can't wait to see the innovation to come

[Whistleblr]

In a world that seems bent on negativity thank you Mr Musk, and everyone involved in his endeavours. Its almost as if Elon himself read my mind every time I said " If I were rich I And he/they are! Thanks again for making an American proud to be an American! GO

Great Job! Love that Falcon 9...just awesome

I want to keep tabs on those mousetronauts!

In 4 years, my son will be looking for a job in the aerospace industry as an engineer. I hope SpaceX will be kind to him.

[towtruckn]

Well!! This pretty much proves it "You don't have to be a Rocket Scientist to be a Rocket Scientist :))))" Go for it SpaceX. Be great to see a few more technical doco's, and tours of some of the testing facilities etc. Hope all goes well with future launches and the re-usables.   Peter

P.S. Real pretty view of the first stage being lit up at night, would have looked amazing from the cape.

[BKD]

Way to go SpaceX!  Loved the internal tank view and the IR view of the engine bell!

Just curious, what is the reason for the instantaneous window?  Shuttle had a window of about 10 minutes or so to get to Station if I remember correctly?  Not enough performance reserve with the uplift on this flight?

[mikigm]

Suggestion: put one camera just above nine main engines of the first stage, or somewhere between them. I bet that would be a sight. And also, you could set up a few high speed cameras to capture lift off from the pad, like those used for shuttle or Saturn V, and those shots could be useful to engineers too...

o_o oh por dios esto esta increible!! espacio!!!! yeah!!!!

Un grand bravo à tous. Bientôt les vols habités
