Looks so different without those legs. Landing legs
And grid fins
if you showed the people from the middle ages this they probably would think it was a real dragon
of all the dragons this is the only real one
Is it weird that I love the sound of blast off from 0:16 to 0:50?
no i fking love it too
Check out some of the vids of shuttle launches. They are awesome when piped throughout a decent home entertainment system. I sometimes play at volumes that the neighbours probably can hear. I think there might be some good vids/sound of Saturn V launches also.
***** Atlas V launches are also pretty great, and the Delta IV (especially Heavy variant... oh baby)
you mean lift off?
If you notice, you will see that as the rocket gets higher, the light from the engine gets larger. That is because the engine exhaust is expanding further sideways due to a drop in pressure.
Delta-V is a product of the weight of the payload so that isn't constant from launch to launch. From the Wikipedia page for the Falcon9: the first stage packs a total thrust of 5,885 kN. And its using good old RP-1 and LOX.
Can't wait for some sort of info or hopefully even video of first stage!
The stage separation is exactly as it was during the live stream. They had problems with the video link and there where many "awaiting vehicle downlink" screens during the launch, one during separation.
That ring at 2:26 is a "stiffener" for the ablative carbon nozzle extension of the vacuum Merlin, it is there to prevent any damage to the nozzle due to vibrations during launch. It is no longer needed once the engine fires and comes off because the heat "destroys" the glue.
congratulations....nice launch yesterday!
If you're talking about the white venting on the side of the rocket near the bottom then it's liquid oxygen boil off. Liquid oxygen is the oxidizer portion of the kerosene + liquid oxygen rocket fuel. It is super cold and so is constantly boiling away. They have to vent it out of the tanks or the tanks would eventually explode from too much pressure.
They did. It slowed itself enough to get back into the atmosphere without any damage. Unfortunately, once back in the atmosphere it started spinning and that centrifuged the fuel so it couldn't maintain the burn.
Elon stated that the next flight will have hardware to prevent spins, but they learned a lot from the flight.
It did work! Getting low enough to crash into the ocean and not break up earlier is actually major progress! It proves that the hypersonic reentry works - grasshopper basically demonstrated the hard part.
This is basically just grasshopper, with a somewhat taller vehicle, once you're near the sea.
Admittedly - the hydroplanes on the side, and deep throttling of the engine, so that it can get up on the step, and plane home are new.
THIS is the next step in space travel. It's time for NASA to make room...
NASA still does incredible stuff. And the lower launch costs will allow to do them more amazing stuff. Nuclear powered flying robot at Titan was just selected as a possible missions along with a sample return from 67p.
@@user-lv7ph7hs7l Yep NASA is great when they are planning missions and thinking long term goals. Leaving the actual rocket building and launching to private companies like SpaceX helps cut costs, increase performance and reliability and avoids the endless bureaucracy that NASA got bogged down with when it came to the Shuttle and other launch programs. NASA and private industry should be working together in a free market to get us to space as a regular venture, instead of the closed market cronyism we got with the moon missions and later with the Shuttle.
Wow, can't wait for that event. Thanks.
Wow I never thought of that, thanks for explaining!
Firefly...!!! The glow of that engine reminds me of the main propulsion unit on the "Serenity" from the TV series "Firefly"...!!! :)
It was basically a brand new rocket. New engines, new engine mounting scheme, larger fuel tanks, new sub systems, new inter-stage, new 2nd stage fairing, etc, etc.. Honestly, it was quite tense at mission control before the launch.
Max Q at t+ 91 secs.
Max Q for space shuttle at t+ 73 secs.
Thanks for the showngo EM!!
Space operations done right.
This is lovely! Its so inspiring Space X! i have been into rocket research and then, so far, i have fired six rockets, and i success ( solid boosters only). I am a Nigerian. I have always had the dreams and plans of running my own space program, and i will by the grace of God! Keep up the good work people! I am sooo proud of your innovations and reengineering techniques! Not far from my ideas too! Indeed great minds think alike! Cheers people! (Thumbs up)
Great video, looks like a few bits are still missing though, pity we dont get to see stage separation super-clearly happen. Such a good launch though, cant wait for the 1st stage video - well done SpaceX!
I wish we could have the full view from the first stage, to see its landing attempt!
Now THATS the Falcon 9 I know and love!
A full KSP instrument overlay would be so cool.
They didn't know whether the thing would blow up on the pad or not make it to orbit. They changed a whole crap load of things between this and the previous launch. Lots of improvements to tank design, engine configuration, tank size, etc. They also had a very very small satellite on board that was originally to launch on a Falcon 1.
We caught a glimpse of the launch here in South Africa :D
Very cool video!
I want to see the separation that got cut out. And the altitude and speed would be great. And maybe some 3D if your feeling creative?
And some annotation of the little bits that fall off would be great so we can learn to interpret what we are seeing. Specifically at 2:26 the ring that comes off the second stage.
I think it´s so amazing that we can do such awesome stuff.. =]
This is such an exciting time 😍
The amount of delta-v depends on the weight of the payload. F9 V1.1 can send around 13t to LEO, which is about 9.3 km/s delta-v.
Thanks for using the metric system.
Looking forward to the coming launch then!
yes, but this stuff has to be incredibly dark, as it is expanding really really fast after exiting the nozzle( there was another video where you could see the exhaust gases forming a huge "shield" behind the rocket because they expanded so fast)
Yeah in fact it could be awesome to have a page with several major data indicators in pair with the live video stream.
With the reliability and safety of flight status of the Dragon program, unicorns or no unicorns, I would strap myself to that candle any damn day of the week.
@5:10 (to the right of the nozzle) the debris being vapourized, with the tail facing away from the rocket. This would be a good footage clip to help explain to students what the solar wind is and what it does to comets.
yes, they cut out all the "awaiting vehicle downlink" screens that occurred during launch.
Meaning fuel pressure, thrust levels, acceleration, EVERYTHING :)
its just O_2. Liquid Oxygen (LOx) is pumped into the tank right before launch and since the boiling temperature is well below ambient room temperature, you have to vent the gas to avoid pressure building up in the tank.
From the post some place that the 1st stage was reignited twice but picked up a spin that made the fuel unavailable to the engine so the soft landing didn't work, then again they didn't expect it to.
No, the Merlin 1D engine (and all previous SpaceX engines) was developed in-house in the united states.
You may be thinking of the Orbital Sciences Antares rocket which indeed uses modified russian NK-33/AJ26 engines (they are more powerful and efficient but also more expensive and harder to manufacture).
That rocket nozzle looks pretty hot!)))
I'll concede that the R&D would have been slowed in the beggining, but they are now starting to turn a corner in that the contracts on the launch manifests are covering cost of operation. The reason they paid only 20% is because F9v 1.1 had to be demonstrated with our without a payload. To help absorb some of the cost to the company, a discount was offered to anyone who wanted to ride along. Remember, this is a brand new vehicle with redesigned engines, avionic hardware/software, & new substems
Great Job SpaceX Team I can't wait until you start launching the Falcon Heavy. :)
Judging by human history, the space age is inevitable. Despite a person's personal feelings on the subject, humans have never ignored opportunity, and Space presents an opportunity that dwarfs everything we've done up until now.
A lot of engineering stuff ends up using customary units (ie feet, pounds) due to incorporating or interfacing with older, non-metric, systems. Spacex has the advantage in that they are using a clean-sheet design and are vertically integrated.
The engines are run rich (more fuel than can be burnt by the oxidiser used), partly because a stoichiometric mix would burn too hot, partly because the hydrocarbons are lighter than oxygen so you get better specific impulse that way. Low in the atmosphere the excess fuel burns in the air. Higher up, there isn't enough ambient oxygen to burn it and it makes soot instead.
Question: why are the exhaust gases in space so deep black?
What I would like to find out is, what was this upgrade for? What does it improve over the last Falcon 9 rocket? Is it cheaper to manufacturer, more efficient than the last?
Nice, next up landing demo.
When can we expect a reusable Falcon rocket Grasshopper test into Orbit (if that makes any sense?
Look at how far SpaceX has come, from worrying that every flight could be the last, barely able to reach orbit. To holding a significant portion of the commercial space transportation market and having the only partially-reusable launch system flying today.
It was solid oxygen from the vents that burned off in the MVac exhaust.
Great flight, though the external camera could've been aimed just a tiny bit higher in my opinion.
How was the glacier volume last time you checked, sir? And when was it?
Return to me with some data and we'll speak.
How much delta-v does that rocket have? What type of fuel, hydrogen with the other thing or something else?
Were did you study aerospace and physics? Zimbabwe?
I thought they were also going to do a test with the spent First stage and attempt to do a controlled landing in the water?
Is falcon 9 the name of the whole vehicle or just the launch stage?
i want to see the onboard view of the first stage reignition, even if it didnt work out :(
The first stage was broken ?
What made this one a demonstration?
Brand new rocket (V1.1 has new engines, is longer on the first stage), new fairing system, new second stage engine, new launch pad, first time going into polar orbit which is much harder than a equatorial prograde orbit.
Is this a re-upload?
If/When first stage comes back and stands up on terra firma and engine cuts and plume clears to reveal an intact readily reusable first stage - it will seem like pure magic - but as Arthur C Clarke once said, "Any sufficiently advanced technology is indistinguishable from magic".
Nice job peoples!
what does KSP have to do with it though?
Another flawless flight congratulations Elon and to all the Space X team!!!
Was there someone in the rocket?
Its own exhaust plume is significantly faster than supersonic. I think it has an exhaust velocity around 4500m/s
They did you just haven't seen it yet. Word has it that it was partially successful but they met their goals with it. Elon said they would try to have some video of it later.
what is CCHP?
They do mention the altitude every once in a while.
that is so cool... I would love to work at spacex !!!!!!!!!!!!!!!!!!!!!!!!!!!!
What is that weird thing at 5:09?
Congrats with Starlink ✨
Actually, full telemetry would be orgasmic :D
IN 100 years, everybody will own there own personal space plane
More thrust, more payload capability. The engines are more powerful and slightly more efficient, the "octoweb" arrangement of engines is more efficient and stable, and the increased tank length gives it increased payload capacity.
Epic win for humanity and for the free market. I
Another great milestone!!!!
Now, take us to MARS!
I can guarantee you that all Engines were design, tested, and made in the US.
If they really, really manage to bring the next rocket down with a quite splash rather than a loud smash, than the Mars mission (and colonization program) would be so much closer, it takes my breath away.
Oh man, most people don't even understand the scope of whats happening!
Its historical! More than that!
ahhh I got ya, Ok, I remember reading that they were expecting failures along the way but it was a spent stage going to crash into the water anyways.
When they simulated on the Kerbal Space Program the spining it made no difference to the fuel.. that's why they did't anticipated it as a problem
It was very nominal.
Even after all these decades, aerospace technology is still relatively primitive, hell, just putting aircraft back on the ground is a somewhat tricky and dangerous manoeuvre
Are the kerbals Okay?
Flying backwards supersonic into it's own exhaust plume - that i want to see. Would be even better if they have telescope tracking shots, but maybe that's too much to hope for.
was that nozzle on the right spraying diarrhea on the launch pad for some reason?
The R&D money that they are getting as part of the CCDev and other ongoing NASA efforts is important to them still. This was a test flight more than anything else. In an interview Elon Musk said customer paid about 20% of what the normal launch fee would have been. So while they wouldn't shut down, they would not be able to function as normal. A lot of their development would be drastically slowed.
Wow well done to SpaceX !
Probably because there is nothing (or little to nothing) to dilute the byproducts of whatever propelled the rockets. It appears to be black because it is obstructing far more light than the surrounding environment, which the cameras have automatically adjusted to compensate for.
@1:20 already 1,000 MPH 4460m/s WOWZERS
they had no idea the rocket was coming down on a spiral.. that's why the engine shutdown because all the fuel was on the walls and not on the bottom to be pumped to the engine.. on the Kerbal Space Program simulator that doesn't matter, if you have fuel you will burn it
Bill was in the secondary payload.
How can i be mad when the future for the rest of us looks so bright))
"yup"? I am glad we agree on something...
At least you didn't kill any Kerbals.
Me Too!
Elon Musk is truly a great man, we shall see some fascinating technologies a lot of us never thought was possible in our lifetime. I strive to work for this man when I graduate.
No, with this launch they now have a launch vehicle that is competitive on the commercial market. While the NASA contracts are still important, they can survive without them.
