STS-122 Launch Scrub Press Conference…

Actually, it was a quick status briefing and not a press conference. There is not yet much information, so they had not to tell a lot. The scrub of Atlantis STS-122 launch attempt on December, 6th has been confirmed once again. Neither Atlantis nor Columbus, its primary payload, will launch into space today. The next launch attempt will be no earlier than tomorrow, but may be farther delayed.

The problem is related to two ECO sensors which had invalid readings. This type of problem is typically discovered late in the countdown, while tanking (that same type of problem prevented me from seeing the STS-115 launch in 2006…). There are four of these sensors.

Troubleshooting is currently underway. They will send out an inspection team to do a quick evaluation of the external tank status. This will take around an hour and a half. There is a technical meeting at noon, where options will be discussed. At 2pm, there is a mission management team meeting, which will decide on how to continue forward. A press conference on the outcome of that meeting is expected no earlier than 4pm.

The firing room guys will work on a routine that provides a 24-hour turnaround. From their point of view, a December, 7th launch is a possibility. However, it is yet uncertain if it is also a possibility when looking at the big picture. So if the missing management team gives a “go” for Saturday, this can be done. If that would be the case, the launch attempt will be at 4:09pm tomorrow (each attempt is roughly 30 minutes earlier than the previous one).

STS-122 unfortunately has a very narrow launch window. It extends just 7 days and possibly one more day if the mission duration is shortened by one day. Even more unfortunate, NASA was hoping for a two-day mission extension to help troubleshoot solar array problems on the international space station.

I will post any updates when I receive them. But I guess I won’t have much more solid information before the end of the 4pm press conference. BTW: all times are EST.

Columbus – Europe’s lab at the International Space Station ISS

Columbus is Europe’s space lab at the international space station. It is ESA‘s most important European mission to the ISS to date and the cornerstone of Europe’s contribution to this international endeavour. Once Columbus is launched, assembled to the Space Station and verified, ESA will become an active partner in the operations and utilization of mankind’s only permanent outpost in space.

It will be launched on December, 6th onboard space shuttle Atlantis (STS-122 mission). Columbus will be transported into Earth orbit in the Shuttle’s cargo bay, pre equipped with five internal rack. Two of its external experiment facilities will be stowed separately in the Shuttle’s cargo bay and attached to the outside of the laboratory module structure in orbit. German ESA astronaut Hans Schlegel will play a key role in two of the three spacewalks or EVA (Extra-Vehicular Activity) scheduled for the mission. During the mission’s first EVA, Schlegel will help to install and power up the laboratory.

As the first European laboratory devoted to long-term research in space, Columbus will further expand the science capabilities of the ISS. In its interior, the Columbus laboratory will provide accommodation for experiments in the field of multidisciplinary research into biology, physiology, material science, fluid physics, technology, life science and education. In addition, its external payload facility hosts experiments and applications in the field of space science, Earth observation and technology.

Columbus is manged from its control center in Oberpfaffenhofen, Germany (near Munic). The center is operated by DLR under a contract with ESA. The Columbus Control Center will work together with mission control in the US and Russia and provide operational oversight, data transfer facility and all other essential services to the Columbus module.

Columbus was built by Bremen, Germany based EADS Astrium, which coordinated 41 suppliers from 14 countries. Its development cost roughly 880 Million Euros. The Columbus module is scheduled to last at least 10 years in space. It was originally scheduled to be delivered to the ISS in 2004, but delayed after the space shuttle Columbia accident.

I am going to view a launch again…

Well, almost… ;) I don’t make it to Florida’s Kennedy Space Center. Of course, I’d love to see Atlantis rocket off the ground and head into space. See that, hear that, small that. But … I got another great opportunity. I’ll view the launch from ESA’s control center for the Columbus module. In some ways, it’s even cooler than standing on the Causeway…

I have written a few articles for a German online portal called raumfahrer.net. It’s a cool site and it is, believe it or not, about astronomy and space flight. I joined it when I wrote about the Cassini mission. I had not much time to do a lot of work, but I kept subscribed to their mailing list.

Last week, a mail arrived looking for folks interested in attending ESA‘s (the European space organisation) launch event in the Columbus Control Center in Munich, Germany. Of course, that drew my attention. But having not done much work… I stood by and waited. Nobody asked for the job, so I finally stepped out and offered to go over (a day before the press accreditation deadline). And, believe it or not, the nice guys from raumfahrer.net agreed.

Reporting on the launch event has now even become a team effort, with me being at one frontline in the control center and someone else being in a local ESA center. We also have some backoffice writers, who will consolidate all our information plus NASA and ESA streams into nice launch update articles. This in itself is a great experience and I am proud to be part of it.

Imagine it: me attending the official launch event as a member of the press and being right at that very place where the Columbus module will be controlled. I think I am a really lucky guy ;)

Even though the center is located in Germany, it is an European effort. The project leader is ESA. Columbus mission control will work closely with US and Russian mission controllers. In fact, the Columbus Control Center will go live as soon as the Columbus module is attached to the international space station. This is scheduled to happen on December, 10th, the day after EVA-1.

Now I am back again at finger crossing. The Columbus Control Center is close to Munic, which is around 300km (roughly 140 miles) away from my place. I can afford to spent one day going to there, but I can not stay for any other launch attempts. So I sincerely hope all will go well on December, 6th. Thankfully, things look quite good. But: keep you fingers crossed. If all goes well, I’ll provide some nice stories and pictures from the other end of the world ;)
