Orion Flight Test Live Launch
- privong 12y agoUnfortunately the feed died for me ~20s before launch (in S. America, and also for several people I was online chatting with [US, Ukraine]). After a bit, the audio briefly came back and I heard the sound of the rocket engine and the announcer say "exploration", which I take to mean the rocket launched. NASA's twitter account also says the rocket lauched[0] and 17 min to orbit[1]. EDIT: Looks like the feed is now revived (12:11 UTC).

- aunty_helen 12y agoIt went down for a lot of people, looking at the twitter feed on the side of http://www.ustream.tv/nasahdtv http://www.ustream.tv/nasahdtv a lot of people are complaining. I was at T-9 seconds and it died.
- awalton 12y agoI was wondering why I missed it. The video wouldn't load for a few minutes and when I finally was able to start viewing again the rocket was already T+2:35ish :/
- jscheel 12y agoApparently reliably streaming video is harder than rocket science.
- exDM69 12y agoTo be fair, there were a ton of international mirrors in popular streaming services (livestream.com, ustream.tv) as well as international news agencies (bbc.co.uk for example) which worked flawlessly. I was watching livestream.com using VLC + livestreamer script and it worked without any issues. The problem is that these mirrors should have been listed clearly at the nasatv site as well as in www.nasa.gov/orion.
- butwhy 12y agoI found it funny how people were posting ustream mirrors. All of ustream was struggling, so all the re-streams were buffering too.
- calinet6 12y agoActually I'd put them on around the same level of complexity from an engineering perspective. Have you thought, recently, how difficult it really is to broadcast video to millions of viewers and all of the individual moving parts that make that happen? It's mind boggling.
- runeks 12y ago> Have you thought, recently, how difficult it really is to broadcast video to millions of viewers and all of the individual moving parts that make that happen? It's mind boggling. Yes. And as far as I can tell, YouTube has it down to a science. If I were NASA, I would let YouTube broadcast the live stream, and embed a YouTube player on the NASA website.
- calinet6 12y ago> "YouTube has it down to a science" Yes, but arguably, NASA has rocket science down to a science too. My point still stands: it's still a pretty complex and difficult thing to pull off with a high rate of consistency.

- organsnyder 12y agoIn their defense, rocket technology has been around for quite a bit longer than IP video streaming.
- exDM69 12y agoStream mirrors: http://www.livestream.com/spaceflightnow http://www.ustream.tv/nasahdtv Can be opened using VLC + Livestreamer script.
- geerlingguy 12y agoThe ustream feed has been the most reliable for me; NASA TV site stream always seems to stutter or go offline at all the most exciting parts of any event.
- drinchev 12y agoI really enjoyed the part when they streamed from the camera attached to Orion and the audio gradually silenced, since the rocket was leaving the atmosphere and no air could be used for a sound wave medium.
- mnw21cam 12y agoThe audio from all the different camera views was the same, I noticed. Notably, the sound obviously came from a microphone on the ground, fairly close to the rocket. This can be deduced by the fact that there is very little delay between the light up and the start of the noise, and the fact that the character of the sound changes when the rocket is a couple of rocket-lengths above the launch platform. While I personally would prefer to have the authentic sound, I can understand why they did it this way.
- FLUX-YOU 12y agoI swear I heard Kerbal music when they were switching between on board cameras and the rendered display (which is really fucking cool).
- sehr 12y agoWatching a live space launch via phone while eating breakfast is quite inspiring.
- connie_lingus 12y agoit would have been even better in a flying car i suppose.
- wmeredith 12y agoSelf-flying car...
- acbergan 12y agoThe stream went down for me too. Anyone have a link for a video?
- mhandley 12y agoThe BBC is also streaming it: http://www.bbc.co.uk/news/science-environment-30327137 http://www.bbc.co.uk/news/science-environment-30327137 Edit: they've stopped now.
- pja 12y agoThere's a launch video on the NASA YouTube channel: https://www.youtube.com/watch?v=UEuOpxOrA_0 https://www.youtube.com/watch?v=UEuOpxOrA_0
- caio1982 12y agoFor those who missed it because of the sudden stream interruption: https://www.youtube.com/watch?v=iCanbuiSywg https://www.youtube.com/watch?v=iCanbuiSywg
- exDM69 12y agoI should point out that "it" is still going on, the mission is rather hectic four hour mission concluding in atmospheric re-entry, splashdown and recovery. There should be plenty of fantastic footage coming up in the next few hours, it's worth staying tuned. Now to grab some lunch to be back in time for the second stage burn to 3200 nm apogee orbit (3640 mi = 5760 km).
- caio1982 12y agoFair and true enough! :-)
- runeks 12y agoHere's the launch in 720p: https://www.youtube.com/watch?v=UEuOpxOrA_0 https://www.youtube.com/watch?v=UEuOpxOrA_0
- rurounijones 12y agoI will cheer every launch but I must admit, after watching so many SpaceX launches, I twiched when I heard "feet per second" and all the other imperial units :p

- EliRivers 12y agoMakes it easier for every country in the entire world, barring the US. Liberia and Myanmar switched over.
- JoeAltmaier 12y agoEverybody pretends to have switched. But even Canadians translate back to Fahrenheit in their heads (ask one).
- robertfw 12y agoI wouldn't say so for celsius but I do find myself changing between feet / meters for certain things, like my height.
- lfuller 12y agoNot true in my experience. I've lived in five different provinces and I've never met a Canadian who uses Farenheit. I've never met anyone under 40 who knows much more than >100F = hot either.
- JoeAltmaier 12y agoMust be age-related, as you say. In fact, since they changed over in the 70's, 40yrold is about the right cutoff!

- ntanitime 12y agoGo Go GO!
- baldfat 12y ago11 parachutes in 3 stages? Now that is some serious engineering. http://news.discovery.com/space/private-spaceflight/final-countdown-orion-spacecraft-by-the-numbers-141204.htm http://news.discovery.com/space/private-spaceflight/final-co... This looks so complex BUT it is coming in so fast (20,000 MPH) into the atmosphere BUT there are so many points for failure. Surprised there wasn't a simpler and safer solution.
- coreyoconnor 12y agoIIRC Space X is going with small rockets to slow decent instead of parachutes. Or in addition to parachutes? I wonder if that would be applicable for the required dV. Or if that is even safer.
- jessaustin 12y agoThe goal is an eventual "soft landing" on a rocket, which isn't feasible with parachutes. Such a rocket could be landed in a specific location, refilled with fuel, and be available for relaunch fairly quickly.
- seanflyon 12y ago"Dragon V2 will initially conclude missions under her parachutes, prior to a later switch to a fully propulsive landing." http://www.nasaspaceflight.com/2014/08/dragon-v2-rely-parachutes-landing/ http://www.nasaspaceflight.com/2014/08/dragon-v2-rely-parach...
- efremjw 12y agoDamn that was amazing! What a perfect launch!! How specialized was the heavy lift configuration for the Orion payload?
- wolf550e 12y agoThe ULA guy in the pre-flight news conference[1] said the rocket is not modified for this flight but they had to do analysis because the payload is not inside the payload fairing. 1 - https://www.youtube.com/watch?v=-jNzvLOHLJw https://www.youtube.com/watch?v=-jNzvLOHLJw
- startupfounder 12y agoThis is really the most amazing day for humankind. Today we took the first step to be a multi-planitary species. Today we took the step to go further. Today we started the countdown clock to step foot on Mars. Today we took only small step in a very long process, but many small steps got us to where we are today, to be able to send a rocket into space (a rocket!!! into space!!!) and many small steps lay before us to take a small step onto the Martian surface. I am inspired!
- Arjuna 12y agoThis is awesome. Two thoughts spring to mind: 1. This is the equivalent of the Apollo 4 mission in that it also flew without a crew, and was used to prove, validate and verify that Saturn V and associated systems were fully mission-capable. 2. Events like this represent our future. Events like this are the catalysts for our future generation. The children around the world (perhaps one or more of your own) that are viewing this event are the ones that will be galvanized to dream, to explore, to go into astrophysics, computer science, mathematics, etc. Just imagine the seeds that are being planted with every event, be it brought to us by ESA, ISRO, NASA, SpaceX, etc. Our 5 year old is asking questions: what makes a rocket launch? Why is the explosion so big? I mean, we're already having conversations that start to tear me up a little, partly because that connection brings me back in touch with my own passion for technology, and partly because it is a small glimpse that represents Our collective future. I'm stoked.
- rquantz 12y agoThank goodness the top comment is no longer about quibbling with units. This is an awesome achievement, and it points to so much more.
- robbiep 12y agoI only wish that this had of been able to attract more publicity. New capsules are always cool and NASA is the king of them all... But as a government body in a tech 2.0 world it doesn't attract the attention or respect that is worthy of its (occasionally bloated, cost-overrun, but nonetheless amazing and awe-inspiring) achievements edit: my apologies, incorrectly thought this was a first flight of the Orion launch system and not capsule
- astrojams 12y agoThis! This!
- melling 12y agoSure, and 2 years after Apollo 4 we landed on the moon. We did a few missions and haven't been back to the moon in 40 years. A Mars mission is 20 years out. You'll be an "old man" by then. It'll take another decade or two to build a permanent Mars base. What we really need is a lot less enthusiasm and a better plan.
- robodale 12y agoIs there a place we can get live NASA Orion Telemetry data?
- orbifold 12y agoThey just stated that the force experienced by crew on reentry would be 8g, while the force on a Soyuz capsule is just 4g. 8g is more than enough for a person to black out, this seems like a major disadvantage.
- api 12y agoLuckily we have better computers than in the Apollo era. The capsule can pretty much fly itself.
- rickr 12y agoWith training and G suits 8G can be sustained. I believe 9G is the limit with this equipment.
- mnw21cam 12y agoThey don't have an option on that one. The acceleration experienced on re-entry depends on the speed of approach. Re-entry from low earth orbit is no big deal, hence being able to slow down with just 4G. Re-entry from a bit further away is more serious, as there is more velocity to shed. Remember that the module has been falling from more than 3600 miles up, which is a lot of energy to get rid of.
- vibrolax 12y agoThe g-load experienced during the re-entry is more a function of the entry trajectory that is flown than the speed of entry. For example, the crews of several Soyuz missions experienced 8+ G's when the so-called "ballistic" re-entry mode occurred due to various systems problems. Apollo crews returning from the moon commonly experienced 6 - 7 g loads during re-entry The US space shuttle's entry profile was designed to limit decelerations to 3 g's (as was the ascent profile). It isn't the speed, it's how you fly the ascent/descent profile. And yes, the conical Apollo capsule form (largely re-used by Orion) is a lifting body that is actually flown through the atmosphere. http://www.chron.com/news/nation-world/article/U-S-astronaut-recalls-terrifying-Soyuz-descent-1759455.php http://www.chron.com/news/nation-world/article/U-S-astronaut...

- pierrec 12y agoSuccessful splashdown! Everything appears to have gone as expected.
- ChuckMcM 12y agoCongratulations to the ULA and Lockheed teams that put this together. It is always a big milestone when you have hardware flying! Let's keep the momentum going!
- nsxwolf 12y agoI have to give NASA a little credit for launching to 3,604 miles. No “manned” mission has gone anywhere near that far since the 70s. I would have expected them to start an infinite series of baby steps, “We went suborbital!” “We went almost as high as the ISS!”
- bayesianhorse 12y agoSince Kerbal Space Program I have a strangely changed attitude towards space flights like this.
