It appears that NASA is at the moment unconcerned should the investigation into the Falcon 9 engine failure on October 7 cause a delay in the next Dragon supply mission to ISS.
The supply cache delivered to the station in early to mid-2011 by the now-retired space shuttle placed the six-person orbiting science lab on a firm footing well into 2013, according to Mike Suffredini, NASA’s space station program manager. “The launch date itself, in January, is not really critical to the program from a supply standpoint,” Suffredini told an Oct. 26 news briefing. “So we have some flexibility.”
In the short run a delay here would not be critical. A long delay, which is unlikely, would however not be good for operations on the station, and illustrates why it is very important to get the Orbital Sciences’ Cygnus cargo capsule up an running as soon as possible.
Dragon has undocked from ISS and is on its way back to Earth.
And here’s a nice description of the “creepy” cargo it is bringing back.
Update: Dragon has successfully splashed down. More here.
Construction workers in space: A spacewalk November 1 will attempt to find and repair a coolant leak that could force a power reduction at the station.
A slight 1.5-pound-per-year leak in the channel 2B cooling system has been present since 2007 and during a shuttle visit last year, two spacewalking astronauts added eight pounds of ammonia to the reservoir to boost it back up to a full 55 pounds. The plan at that time was to top off the system every four years or so to “feed the leak,” replacing the lost ammonia as required.
But over the past few months, engineers saw the leak rate suddenly quadruple, either because something changed at the original leak site or, more likely, because another leak developed somewhere else in the system.
Whether the leakage was caused by space debris or a component failure of some sort is not yet known. But the result is: If the leak continues at its current rate, the coolant will drop below a 40-pound safety limit and the system will shut down by the end of the year or shortly thereafter, taking power channel 2B down with it. While the space station can operate without the full complement of power channels, the loss of channel 2B would force flight controllers to power down equipment, eliminating redundancy and reducing the amount of research the crews could carry out.
The failure last August of the second stage of a Russian Proton rocket is causing more problems: the stage exploded in mid-October and the debris is now a threat to ISS and other satellites.
With a successful Soyuz docking today, ISS is back to a full six person crew.
Early today a Soyuz rocket successfully lifted ISS’s next crew into orbit.
Orbital Sciences has delayed the first demo launch of its Cygnus cargo capsule until March 2013 at the earliest.
The schedule for Antares itself has not been delayed. Launchpad tests are still scheduled to begin next week, with the first engine test set for early November, and the first launch of Antares set for December.
They don’t explain the reason for the Cygnus delay. I suspect they simply decided to be realistic. It was always unlikely that the first Cygnus launch would follow only a month after the first Antares launch, especially if there are any kinks in that launch.
It’s official: Singer Sarah Brightman has purchased a ticket to fly to ISS in a Soyuz capsule.
The astronauts on ISS have opened the hatch to Dragon one day early.
At 9:04 am (Eastern) the Dragon capsule successfully completed a hard docking with ISS.
Confirmed: One engine of the Falcon 9 exploded during launch.
Video at the link. The other 8 engines picked up the slack — as designed — and got Dragon into orbit.
This spectacular engine failure will of course have to be reviewed. However, if I were a commercial satellite company looking for a rocket to get my satellites into orbit, this failure would be recommendation, not a deterrent. The Falcon 9 demonstrated that even if one engine fails (and this one did by blowing up!), the rocket can survive the failure and make it to orbit. If that isn’t clear proof that this is a well designed and well built rocket, nothing is.
Another success for SpaceX: Dragon is now in orbit.
It’s now official: NASA and the Russians have agreed to fly a two-person year long mission on ISS beginning in the spring of 2015.
NASA has denied that this agreement has any connection with the Sarah Brightman/Russian deal, but I still wonder. Either way, it is very good news. Not only will they finally be using ISS appropriately, a mission like this will generate some real excitement for space exploration that the repeated boring six month expeditions to ISS have failed to do. Even better would be to schedule a two year mission, simulating a journey to and from Mars.
Irony of ironies: In order to buy her seat on a Soyuz capsule Sarah Brightman outbid NASA, bumping its astronaut out.
This was a win-win for the Russians. They get paid more by Brightman than by NASA (over $51 million), and they finally get that year long mission they’ve been campaigning for for years. Because Brightman has taken one of NASA’s seats, the U.S. agency was forced to agree to the extended mission in order to maintain a presence on the station throughout that time period. Otherwise, their astronaut would come home and be replaced by Brightman, but for only ten days.
The head of Russia’s manned program said today that the first yearlong mission on ISS will begin in March 2015.
This appears to be another case of the Russians trying to use the media to pressure NASA into agreeing to the mission. I hope it works.
Europe’s ATV cargo freighter finally undocked successfully from ISS on Friday.
The undocking of Europe’s ATV cargo freighter from ISS has been delayed again.
No explanation, which is worrisome. Then again, this might be nothing.
The failed undocking of Europe’s ATV cargo craft from ISS earlier this week occurred because the astronauts used the wrong computer code.
They have rescheduled the undocking now for Friday.
The competition heats up: Singer Sarah Brightman appears slated to be the next tourist to fly to ISS.
A computer glitch prevented the undocking of the European ATV-3 cargo vehicle from ISS today.
Undocking of the European Space Agency’s third Automated Transfer Vehicle, or ATV, from the aft port of the Zvezda module had been scheduled for 6:35 p.m. EDT (GMT-4). Cosmonaut Yuri Malenchenko attempted to send a command to begin the undocking sequence on time, but the command apparently never reached the docking mechanism.
I am not sure what will happen if they cannot pin down the problem. For example, it is unclear whether the cargo vehicle can be reprogrammed to be manually controlled. Also, it presently blocks a docking port. Is that port needed for the next ATV freighter as well as for other craft, such as Progress freighters? If so, this could become a serious problem.
Boeing has indicated that it might shelve its CST-100 manned capsule, despite their recent almost half a billion dollar contract award from NASA.
This possibility illustrates why Boeing is losing market share, not only in space, but in the aviation industry. The article suggests that the NASA contract might not be enough to pay for CST-100, and that Boeing is unsure there is enough private market to make up the difference.
“That’s just for the ISS. That’s kind of the basement,” adds Elbon. More flights than those to the ISS are required he says, and Boeing is cautious about over-committing itself while future revenue streams are unclear.
I say bull hockey.

The competition heats up: October 7 has now been set as the launch date for the first operational cargo flight of Dragon to ISS.
Astronaut Sunita Williams completed the first simulated triathlon in space this past weekend on ISS.
After “swimming” half a mile (0.8 km), biking 18 miles (29 km), and running 4 miles (6.4 km), Williams finished with a time of one hour, 48 minutes and 33 seconds, she reported. The space station has its own treadmill and stationary bike, which use harnesses and straps in place of gravity to keep astronauts from floating away. To simulate the swimming portion of the race, Williams used what’s called the Advanced Resistive Exercise Device (ARED) to do weightlifting and resistance exercises that approximate swimming in microgravity.
Three astronauts have safely returned to Earth from ISS.
More important, the Russians have now delayed the next Soyuz manned launch to ISS for a week due to “some malfunctions [that] have appeared in one of the devices of the decent module.”
They also say the delay is to avoid a flight conflict with the next Dragon mission on October 15. This is interesting in that the last word we had from NASA was that the Dragon launch could occur as early as October 5.

SpaceX’s first official cargo flight to ISS could occur as early as October 5.
In a spacewalk today astronauts successfully overcame a stuck bolt to install a replacement power unit.
Because of the failure to replace a power unit during last week’s spacewalk, the U.S. portion of ISS is now in a brown-out, with a 25% reduction in power.
They plan a second spacewalk tomorrow to try to fix the problem.
The competition heats up: On Friday SpaceX successfully completed a launch pad dress rehearsal for the next Falcon 9 launch to ISS.
