We’ve been streaming NASA TV on the web in earnest since 2004, when the Mars Exploration Rovers landed. Then 50,000 people watched our mission coverage on RealMedia, in windows probably not much bigger than today’s smartphone screen. Seven years later, more than 560,000 people watched the launch of the last space shuttle mission, many of them on an HD feed in Adobe Flash that filled a 22-inch monitor quite respectably. Others watched on their phones and tablets. Over the course of the mission, all that video meant that in two weeks we shipped almost as much data (1.2 petabytes, or more than 1.2 billion megabytes) than we did in all 2010.
And, unfortunately, we can’t afford to keep that up. Before adding HD and iOS streaming, we were streaming about 50 TB a month. Now we’re averaging five times that. This doesn’t fit well under a firm fixed-price contract. So while we’ve been able to find some additional funds, we’re also going to have to reduce our usage somewhat. Specifically, we’re going to:
- Continue streaming the NASA TV public channel in HD at its current top resolution
- Continue streaming to iOS devices at the current top resolution
- Shift the ISS video stream to Ustream. (The mission audio stream, and the NASA TV media and educational channels, may also switch to Ustream.)
- Discontinue streaming in RTSP format.
That last will affect users of older Android phones, those operating on OS 2.1 or earlier. Unfortunately, the cost of the RTSP stream was quite high (higher even that the main HD feed of NASA TV) and the audience was never very big, fewer than 800 during peaks that saw hundreds of thousands of users on other formats. So it simply didn’t make sense to keep doing it that way. While we hate to shut down any capability, we do have to manage the taxpayers’ money smartly.
You’ll see these changes take affect late next week. We’re sorry for any inconvenience.
