It looks as if the problem has to do with the Dragon's thrusters

SpaceX sent its Dragon capsule to the International Space Station (ISS) for the third time this morning, but it appears something went wrong after the launch.

Today's Dragon launch, known as the CRS-2 mission, was the capsule's third trip (but second official cargo delivery) to the ISS. It was scheduled to launch from Cape Canaveral, Florida at 10:10 a.m. ET.

The launch was successful right up to the point of entering orbit. But right after the Dragon vehicle was released (it traveled atop the Falcon 9 rocket), a problem occurred.

As of right now, it looks as if the problem has to do with the Dragon's thrusters. SpaceX CEO Elon Musk is already tweeting about the issue.

"Issue with Dragon thruster pods," Musk wrote on Twitter. "System inhibiting three of four from initializing. About to command inhibit override."

The thrusters allow the Dragon capsule to move about in orbit.

Shortly after that tweet, Musk also posted this:

"Holding on solar array deployment until at least two thruster pods are active."


The CRS-2 mission entails the carrying of 1,200 pounds of scientific experiments, food for the astronauts and even some entertainment, such as a copy of "Up in the Air" by the rock band Thirty Seconds to Mars.

Dragon is due to arrive at the ISS Saturday at 6:30 a.m. ET., unless current issues slow that process down.

The Dragon flew to the ISS for the first time in May 2012, then made its first official cargo run in October 2012 as part of a $1.6 billion deal with NASA.

DailyTech will update this article as more details on the Dragon's issue in space today are revealed.

Updated 3/1/2013 @ 1:30 PM EST
Elon Musk's Twitter reveals that the solar array deployment was successful, and that SpaceX is now attempting to bring up thruster pods 2 and 4.

Updated 3/1/2013 @ 3:00 PM EST
Elon Musk reported that pods 1 and 4 are back online, and the thrusters are engaged. Also, the Dragon has shifted from free drift to active control.

Updated 3/1/2013 @ 5:00 PM EST
According to Elon Musk's most recent tweet, "thruster pods one through four are now operating nominally." He added that they were getting ready to raise orbit and that all systems were back in action.

really? they sent up digital information stored on physical media? what is this, the 2000s?

A CD weighs about 15 grams. With case it's about 60 grams.

The Falcon 9 costs about $1300/lb of payload put into orbit. So that 15 gram CD cost $43 to send up there. If they sent it in a case, it cost $172.

Next time, stream the MP3s. (In seriousness, the vehicle probably had plenty of reserve payload capacity - i.e. extra fuel to burn. So the weight of the CDs didn't really cost anything except a 0.001% reduction in a let's say 10% safety margin. But if the mission had had a payload closer to the max capacity, you don't want to be sending up trivial things like CDs.)

The rocket is going up regardless of if you stick a CD on it (with case attached, probably) or not. You might as well use any spare capacity there is, because the price of the launch is exactly the same even if you were to launch the rocket with just its mission payload onboard.

So your price of $43, or $172, is incorrect; the price is actually $free.

It all adds up to opportunity cost. There may be other useless crap to send up there.

Also, there isn't a lot of 'extra room' on the ISS. They are going to have to find a place for it that is held down and then have to dig it up if they want to hear it. That kind of makes it useless since it can't be handled the same way that their other music does.

Oh, and FYI, there probably isn't copyright law on the ISS.

Everyone forgets how much their data service provider is charging them for their data access fee. If they were sending up a single 650 MB CD worth of data on Verizon's international data roaming charges, it would be

$0.02/KB * 650 MB = $13,000.

Still cheaper to send it by rocket power. Faster too ;)

I'd assume bandwidth is a fairly precious commodity between the ground and the ISS.

I doubt they will let anyone install a file sharing app on one of the space station computers :)

You don't need file sharing to get digital copies of music.

It is probably a paid ad or a publicity stunt for the song/band.

I agree it's probably just a publicity thing or maybe an inside joke since the band's name is "30 Seconds to Mars" and the title is "Up in the Air"

Never underestimate the bandwidth of a station wagon full of mag tapes.

Perhaps that needs updating to Never underestimate the bandwidth of a spaceship full of CDs.

One hundred billion dollars spent to end up with a space station that has limited comms bandwidth - that would be quite sad. Nearly as sad, would be spending $5,000 to send a CD into space. Optimistically, it may be on a microSD card, which would make a smaller and cheaper joke.

How do you know it's not a yet-to-be-released nanoSD? They probably downloaded the album through iTunes.

What pipe have you been smoking? You think it is some boondoggle? ISS is important for all kinds of research that is either expedited by the environment or can't be done on earth. Anyone who thinks ISS is just money down the drain and doesn't return at least is cost in valuable research, doesn't know what they are talking about.

While I would never say that the ISS was "just money down the drain", I will say that I believe that the return on investment (ie - number and magnitude of things learned vs. money spent) has not been all that spectacular in comparison to other space exploration missions.

That said, the money spent to send a CD into orbit, in relation to the much higher cost of ANYTHING sent to orbit, is absolutely trivial and I think it's ridiculous that anyone is complaining about it.

I dunno, you tell me. 1901... that was in the 1900s, right? What about 1913? Was that in the 1900s? Yeah, I'd say we're in the 2000s still. You might as well have said, "What is this, the 21st century?"

You know what, come to think of it... if I didn't know better, I'd venture so far as to say that these engineers are possibly smarter than you, and maybe they know what they're doing.

CDs

Total waste of money. It costs gobs to launch things into space, based on weight. How many CDs can fit ripped onto a flash drive? One flash drive loaded with music would cover the ISS music needs for years.

According to various sources the Dragon's cargo capacity to the ISS is about 7,300 lb. If they only sent 1,200 lbs it is severely underutilized. (Probably because it's still very much an untested platform, and no one is going to risk really important cargo until there have been at least several successful flights). So they could have loaded the thing up with hardcover books, and it still wouldn't matter at this point.

They could probably launch with a lot less fuel though to save money.

Fuel is an exponential cost multiplier; the more weight launched, the more fuel needed, and the more fuel needed to carry the extra fuel.


Just a bump in the road ...
