A computer glitch prevented the undocking of the European ATV-3 cargo vehicle from ISS today.
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 and the fear of competition
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.

Astronaut Sunita Williams completed first simulated triathlon in space this past weekend on 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.

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.

Two astronauts on ISS completed an eight hour spacewalk today, extended because of problems with several stuck bolts.
Williams and Hoshide initially progressed well through their tasks, but the astronauts struggled with difficult bolts when removing a faulty power box from the exterior of the space station, and then again when replacing the defunct unit with a new spare.
More information here. In the end they were forced to leave the replacement unit only temporarily attached because the bolts would simply not screw in. It was thought there might be debris in the screw holes.

More rumors about a year-long mission on ISS
The possibility that NASA might finally agree with Russia’s repeated request to fly a year-long mission to ISS grew stronger this morning with two stories:
- NASA gets set for yearlong stints on space station
- A year on the ISS: Good for tourists – and science
The first, by James Oberg, digs into the underworld of NASA politics to find that plans might very well be more advanced than NASA is letting on:

NASA today announced that recent research on ISS into bone loss due to weightlessness has found that proper exercise and diet can stabilize bone loss.
Good news! NASA today announced that recent research on ISS into bone loss due to weightlessness has found that proper exercise and diet can stabilize bone loss.
Past Russian research on Mir had found that exercise and diet could limit the bone loss, but not stop it entirely. The key difference in this recent work seems to be the use of more sophisticated exercise equipment.
If this research holds up, it eliminates one of the most serious obstacles to interplanetary travel.

This is in contrast to a previous attempt on August 15, which cut off prematurely.

What do you do with a giant space station when its lifespan is over?
What do you do with a giant space station when its lifespan is over?
The article notes that no date has been set for deorbit, and that it likely will not happen before 2028. The article also includes information about some of medical and engineering problems of long term weightlessness that have been discovered on ISS, and how engineers have attempted to address them.
Unfortunately, some of these problems, such as the recently discovered vision problems, remain unsolved. It is a shame that while Russia wants to do multi-year missions on the station to study these issues, NASA continues to resist.

Monday’s successful spacewalk by two Russian astronauts has prepared ISS for the arrival of a new Russian module.
I should have posted a link about this spacewalk earlier. What is important however is that the Russians continue to move forward, though slowly. And they continue to come up with simple solutions to problems, such as the extra layer of shielding for the living quarters on ISS, installed during this spacewalk.

Russia is considering shortening the time it takes for its Progress and Soyuz capsules to reach ISS after launch, from 50 hours to 6.
Russia is considering shortening the time it takes for its Progress and Soyuz capsules to reach ISS after launch, from 50 hours to 6.
The long travel time was designed to save fuel at launch — thus increasing payload — by allowing orbital mechanics to bring the capsule and station together. I wonder then why the Russians are considering this change. Have the figured out a way to save the fuel in other ways?
