Phase 3D/AO-40 Update

The month of February continues with on-going recovery efforts of AMSAT OSCAR 40.

The AMSAT-DL web site is currently featuring the following statement:

AMSAT OSCAR 40 is still in its seasonal limitations which will (naturally) end by April. If the announced de-spinning routine is successful, the (major) planned recovery efforts of AO-40 could begin earlier. Testing of this software routine is now underway.

The S-band middle beacon is operating nominally on 2401.323 MHz and can be heard best between MA-2 and MA-14. The MA numbers will slightly change due to changing attitude. Eclipses around perigee do not appear to have a negative influence on the satellite power budget according to received whole-orbit-data.

This year's AMSAT-DL Symposium will take place very soon and will have at least three lectures about AO-40:

AMSAT-DL Journal editor DL6DBN and AMSAT-DL executives DJ4ZC and DB2OS are scheduled to attend.

ALON/ALAT is currently 248/-7, as last listed on the AMSAT-DL web page.

The latest orbital parameters are as follows:

Satellite:      AO-40
Catalog number: 26609
Epoch time:     01033.57694040
Element set:    33
Inclination:    5.7772 deg
RA of node:     225.7720 deg
Eccentricity:   0.8134720
Arg of perigee: 215.7457 deg
Mean anomaly:   44.3265 deg
Mean motion:    1.26935859 rev/day
Decay rate:     -4.4e-07 rev/day^2
Epoch rev:      119
Checksum:       287

The AMSAT-UK web site is also featuring news of AO-40:

AO-40's situation is stable with good battery conditions. If command  stations are unable to change the attitude then the wait could last until April before favorable reception conditions return.

Before AO-40's launch, a long period was anticipated before full commissioning was expected to be completed. It now appears likely that this waiting period will be actually less than expected. The method of measuring the Sun angle with solar radiation is not a trivial activity.

There are still strong hopes that the ATOS motor can be used later to adjust the orbit to something more suitable to general communications.

Although optimism is certainly not a guarantee of future success, AMSAT continues to believe that there will be successful long-term amateur radio communication through AO-40.

AMSAT-UK wishes the command team the best of luck in their hard work.

Stay tuned to AMSAT News Service, the official source of AO-40 news and information.

New AMSAT-NA Web Service

AMSAT-NA Vice President of Electronic Publications, Paul Williamson, KB5MU, recently informed ANS of a new web service -- messages from the AMSAT-NA bulletin board are now available on the web!

Indexes by date, thread and author are available. Archives of the current messages for several convenient periods are also listed, as are monthly archives (to February 1998). If a satellite operator needs to unsubscribe from the mailing list for a period, they can then (very conveniently) review what was missed by browsing the web archives. Some stations may even find the web archives easier to use than the mailing list itself!

According to KB5MU, web pages for the SAREX mailing list will be added soon, followed by web pages for the other AMSAT-NA public mailing lists.

ANS editor NN0DJ, has used this new service on several occasions since its inception. Dan finds the new service very easy to use and extremely beneficial (along with a very easy, user-friendly web page)!

See http://www.amsat.org/amsat/archive/amsat-bb/index.html.

Atlantis Headed to ISS

The space shuttle Atlantis roared into space on Wednesday, February 7, 2001 with a primary objective to deliver and install the U.S.-built Destiny Laboratory onto the International Space Station.

According to NASA, Destiny is the centerpiece of the station and the site where unprecedented science experiments will be performed. In addition, STS-98 astronauts will relocate a pressurized mating adapter from the Unity Node to Destiny.

While at the station, the astronauts will conduct three space walks and use Space Shuttle Atlantis' robotic arm.

No amateur radio operation is scheduled from the shuttle during this mission.
