AO-40 Update

Command station team member Stacey Mills, W4SM, tells ANS of the latest AO-40 developments:

Attitude determination on December 12th showed that ALON was 356 and ALAT was at -10.5. This was slightly more negative than originally expected. Following this attitude determination the AO-40 command team has decided not to lower ALAT any further, instead we plan to use the mystery effect to AO-40's advantage during the next few weeks.

We can do this safely.

When we regain solar sensor lock in the latter half of January 2002, we will then begin station keeping (stopping AO-40 from drifting backward further in ALON) and we will raise the ALAT back to 0 shortly thereafter. Command stations will then chase the Sun slowly toward 0/0, getting there in April as previously described.

The good news is that with ALAT in this range, we should be able to keep the transponders active for part of the orbit (right after perigee) throughout this time period.

Happy holidays from W4SM and the AO-40 Command Team!

Yoshi, JA6XKQ, and the JAMSAT team (along with the RUDAK and SCOPE team) informed ANS that they are glad to release several new pictures from the SCOPE cameras onboard AO-40.

RUDAK command station member Jim White, WD0E, captured the latest pictures on December 12th. One of the pictures is the first photo from Camera A. The pictures are available at

New ISS Crew Completes First Week in Space

Expedition-4 Commander Yury Onufrienko and Flight Engineers Carl Walz and Dan Bursch have completed their first week of independent operations aboard the International Space Station, after bidding farewell to their predecessors. The Expedition-3 crew (and the crew of Endeavour) successfully completed their journey back to Earth.

Aboard ISS, Onufrienko, Bursch and Walz spent the week activating science experiments, including a cell growth experiment used to study colon and ovarian cancer cells and human kidney cells. They also continued to familiarize themselves with their new home, unload the Progress 6 cargo ship, and unpack equipment and supplies brought aboard by Endeavour.

Each member of the new crew holds an amateur radio license. Commander Onufrienko is RK3DUO, Bursch is KD5PNU, and Walz holds KC5TIE. All three are expected to be on the air regularly for school contacts and possible open QSO's as time permits.

The crew will continue experiment work and they will have a day off on Christmas day to observe the holiday. The station's food stores include turkey and some other traditional holiday foods. The crew also will observe a holiday on New Year's Day.
