WRV1 Wheel Hubs
Jörg has now finished manufacturing four wheel hubs for the WRV1 rover prototype. For reference, I have also included the blueprint that has been posted earlier. Personally, I am very impressed by seeing the real thing look like on the specifications - I wish we could do the same in the software world ;-)

Arianespace Launches New WebTV Site
If you like to watch rocket launches you might be glad to know that Arianespace has launched a new WebTV site called VideoCorner just a few days ago.
They broadcast live coverage, the next one 12 Feb 22:09 UTC, as well as archived videos of Vega, Soyuz, and Ariane 5 launches and related topics. They even got a podcast area now :-)

News from Vietnam
Inspired by our Open Source Communication Lab, our friends from Vietnam have started to play with software radios using the USRP and GNU Radio. After a few weeks of study they are now able to receive Automatic Picture Transmissions from the NOAA weather satellites as well as signals from current amateur radio satellites in low Earth orbit.
Inevitably, they have now formed a group of young engineers who are interested in ham radio, electronics, robots, astronomy and space exploration. At the moment, they work in the newly established FSpace lab of FPT Corp. where Thu (who is active on our forum) used to be a software engineer. He has now quit that job to pursuit his dream of space exploration.
Their current project is to design and manufacture a nanosatellite which will measure about 10x10x30cm and weight about 3kg. They expect to have it ready in 18 months (starting from 1/1/2009) and launch it to LEO (600-800km, sun-sync orbit) by the end of 2010. This is the first time they've ever worked in a real space mission. While they understand that there are many things to learn and many difficulties ahead, they are confident that they can do it if they try hard. Currently, they have 4 full-time people (Thu and the other 3 in the photo) and about 10 supporters/collaborators of the project.
PS: Thu has recently passed his amateur radio exam and has now the callsign XV9AA.

Jaluro off the Leash
Let's round off this week with some breaking news about Jaluro and a story about just how crazy we are.
Jaluro is now off the leash! You may remember the first Jaluro video posted about 6 weeks ago when Tobi was making the first tests using a wired connection. Now, Jaluro has got a wireless control and Tobi recorded the video below showing his first outdoor tests using the wireless interface.
We were also happy to see some clear evidence (see NASA and Caltech Test Steep-Terrain Rover) that the two-wheeled concept is a very viable option for planetary exploration. We wish Jaluro could get the same media attention as JPL News ;-)
The evening before Tobi recorded this video, we were hanging out on our IRC channel (#teamfrednet) having some casual chats about "stuff". Suddenly, Tobi got the idea of setting Jaluro up so that Anders and myself could send commands to it from Copenhagen! Before we knew it, we were also broadcasting it live via ustream.tv so that everybody on the channel could watch Jaluro do something as we were sending commands to it. It was a crazy Thursday night that ended around 3 AM CET. You can read the IRC log here.
By the way, anybody is welcome to hang out on our IRC channel. It is #teamfrednet on irc.freenode.net or you can use a web interface (choose a real nickname instead of mib_***).
I'll be back next week with more crazy news.

Scheduled Radio Contact with the ISS
If you happen to live in Europe, you'll have the chance to listen to the astronauts from the International Space Station as they talk to students from Städtisches Gymnasium Herzogenrath in Germany. The event is scheduled for Saturday Feb 7 and it will begin at approximately 10:36 UTC.
You will need a radio receiver capable of receiving 145.800 MHz narrow FM. The signals from the ISS are usually rather strong and a handheld scanner should be able to receive audible signals.
I don't exactly know which astronaut will be speaking but they will use the ham radio call sign OR4ISS.
The students will ask as many of the following questions as time permits:
1. To what extent do we on earth profit from your experiments on the ISS?
2. What are the aims of your present mission?
3. How much energy do you need daily and what kind of energy is it?
4. What about radiation on the ISS? Does it harm your health?
5. Have you had any problems with oncoming meteorites or space debris?
6. Which qualifications do you need to be on such a mission?
7. What were your feelings and emotions during lift off?
8. Do you lose your sense of time on the ISS?
9. How do you spend your free time on the ISS?
10. Have you got any room for your personal belongings?
11. What happens if you are ill?
12. What happens to the human body if you stay in space too long?
13. How often do you see the sunrise on the ISS per day?
14. What happens in case of an emergency, for example if the ISS is on fire?
15. Can you sleep well in a state of zero gravity?
16. How do you wash your hair?
17. How many experiments do you do a day?
18. Have you and your colleagues become friends?
19. What would you say is your most important experience on the ISS?
20. When do you think will mankind be able to leave our solar system?
ARISS is an international educational outreach program partnering the participating space agencies, NASA, Russian Space Agency, ESA, CNES, JAXA, and CSA, with the AMSAT and IARU organizations from participating countries.

Feature Recognition and Tracking
Autonomous feature recognition and tracking can be a useful navigational aid during the final phase of the lunar landing. This video shows a quick-hack prototype for recognizing and continuously tracking lines and circles at 15 frames per second (the red lines in the second part of the video).
Of course, the situation will be more difficult during lunar descent because deviations from mathematical lines and circles will occur. So there is still a lot of work to do :-)

Update from the Team FREDNET Lunar Babies Club
In the big rush I almost forgot to bring you the latest edition of this rather occasional newsletter - shame on me...
Lunar Baby no. 2
Aaron Magnus Krieger-Kuritko, born 27 Nov 2008 20:00 GMT. Weight: 3,920kg. Proud parents: Theresia and Tobias Krieger Kuritko (yes, Tobi is the creator of Jaluro - really beats me how he has time for a job, family and to work on Jaluro).
Lunar Baby no. 3 - is already in the loop and you can try to guess the date and time of arrival. The person who comes closest will receive a free Team FREDNET mission patch. The deadline for submitting your guess (as a comment to this post) is Saturday 14 Feb 2009 23:59:59 UTC.
