Rymddrkten Suitsat kanske slpps ut frn ISS i januari. Hr nedan str det dock december, men det har blivit frskjutet och det r allts januari, eller kanske tom. februai, som gller. Ls nedan (som r en del av hela bulletinen):

A note to readers of ANS. Since the SuitSat project encompasses both a free floating unmanned satellite and is being hand launched from a Manned satellite, there will be some double postings regarding the SuitSat project on both the SAREX and AMSAT-BB mailing lists. If you are not currently on the SAREX list, you may want to check the AMSAT link to sign up for both so you do not miss the additional projects coming this year, and early 2006.

SuitSat, Slow Scan TV from ISS in 5 weeks?

Slow Scan TV from the SuitSat project, launched from the International Space Station, may be activated in as little as 5 weeks. Note: All dates are subject to change.

At the present time there are tentative plans to have a Space Walk (EVA) taking place from ISS sometime around December 8, 2005. It is possible that during this Space Walk, the ISS crew may Hand launch the ARISS SuitSat
project during that EVA mission. Again, all date are subject to last minute changes. Please Keep monitoring the ARISS and AMSAT web pages for more updates.

The SuitSat project is a free floating Unmanned satellite that will be running on Batteries Only! The life span of the project will be limited to the power in the batteries. SuitSat may last as little as 1 week or as long as 6 weeks. So it is very important for you to get your satellite monitoring station ready now. You should not wait for the Official activation date, because you may miss the opportunity to hear the new bird.

I will keep posting updated links for the SuitSat project as they become available.

Trots att SSETI Express slutade fungera lyckades den snda ett tag och fr drfr ett Oscar-nummer:

The SSETI Express Team has met the requirements to earn their satellite the official designator of Express Oscar 53, or XO-53.

Bill Tynan, Past AMSAT President, and presently OSCAR number coordinator, wrote to the SSETI Team, From the information you have sent to the AMSAT-NA Board and officials regarding this project, it has been determined that the SSETI Express spacecraft IS qualified to receive an OSCAR number.

Bill continues, Therefore, by the authority vested in me by the AMSAT-NA President, I am pleased to issue this new amateur satellite the designation Express OSCAR – 53, or XO-53 as you requested. Congratulations to all involved in the successful completion and launch of XO-53 .

For information about the requirements that must be satisfied in order to obtain an OSCAR designation refer to:

Dear All

During the AMSAT-UK Colloquium in late July it was announced that it was expected that the POSAT satellite would be reconfigured for amateur radio use.

We are pleased to confirm that this is still the plan but it is taking alittle longer than expected to make the necessary non-technicalarrangements.

The final operating configurations will take into account the various options discussed on the AMSAT-BB within the constraints imposed by the operating system on board and by the load on the command station.

As soon as we have more detailed information we will make a further announcement

En Diplexer kan vara bra att ha fr att kra 2 olika antenner p samma antenningng eller tvrtom.

Ett annat bra omrde r nr man snder p 145mhz upp och lyssnar p 435mhz ner och det uppstr blockering p den mottagna 435mhz signalen. Det gr d utmrkt att stta en diplexer p nedlnken och filtrera bort 145mhz signalen.

Dom hr finns att f tag p i handeln men hr r en fin beskrivning med bilder hur man tillverkar den sjlv.

Nu kommer det som mnga vntat p!

Dom ska provkra PE1RAH:s transponder och slr ver den 17/11 5:00 UTC. Fungerar allt s r den planerad att kras i 4 veckor.

Hr kommer information om vad som hnt med SSETI:

On Thursday, October 27, at 22:20 CEST SSETI Express went into a safe mode due to an undervoltage caused by battery charging problems. The operations team is working actively to resume nominal operations of the satellite and is receiving tremendous help in the process from the
amateur radio community. At the time of the anomaly many mission milestones had already successfully been met.

Careful analysis of the data received, coupled with ground-based computer simulations and hardware tests, strongly support the proposed theory of a specific component failure in the excess power dissipation system.

Ground-based hardware tests confirm the possibility of a further failure mode of the specific component, which would allow the batteries to charge and the spacecraft to operate once again.

Testing is ongoing to ascertain the specific likelihood of this, and to investigate other possible alternative explanations.

Given that the spacecraft is currently inoperable, the mission cannot continue as planned. It is therefore on indefinite standby , pending the technical possibility of re-activation of the spacecraft.

The team remain hopeful and vigilant. The primary groundstation and mission control centre are being configured for autonomous monitoring of the spacecraft, such that if it reactivates the team will be immediately
alerted and ready to resume the mission. The educational goals of the mission continue to be met daily as we try
to analyse and understand the events since the launch.
