NASA Time Line Requires SAREX to Back Off STS-95

The Space Amateur Radio Experiment (SAREX) payload originally scheduled to fly on Shuttle Mission STS-95 this October has been removed, along with nine other payloads from the flight manifest due to tight constraints on the crew's payload activity timeline.

Flight managers, after reviewing all of the planned STS-95 activities, concluded that there was a need to reduce the overall manifest and took the action of removing SAREX and some other secondary payloads. This action was done to insure sufficient time to accomplish the major objectives of the flight and insure the overall success of the busy mission.

NASA expressed regret at having to take this unfortunate action, in particular, having to delete educational activities from STS-95. NASA, SAREX, ARRL and AMSAT were in the throes of planning the activities for STS-95 when the official word came concerning the mission. Four US schools that had been selected for SAREX QSO's will now be first in line for consideration on future missions, such as STS-93 and the International Space Station.

All future shuttle missions are heavily loaded with activities that revolve around building the International Space Station. But SAREX has an imminent place in NASA's future plans for the few shuttle missions that will support it, such as January's STS-93. The SAREX Working Group is looking at another mission for 1999 that may be suitable, too. SAREX also continues to have a big place within NASA's International Space Station plans, which involve a temporary and a permanent Amateur Radio station onboard.

Thank You from DJ4ZC

AMSAT-NA recently received a note of thanks from Dr. Karl Meinzer, DJ4ZC, AMSAT-DL President and Phase 3D Project Leader. The note reads as follows:

"After the announcement about our launch situation, I received a little under 400 letters until now. I wish to express my appreciation for the support and suggestions that were mailed to me, and I find it impossible to answer all these letters individually. All letters I received were very encouraging and not a single real complaint was voiced.

This really taught me two things. The amateur community, and in particular the AMSAT community, is looking forward to the launch of P3-D as a real enrichment to our service and they understand the difficulties in securing a launch of a 600 kg spacecraft in a highly competitive environment. Second, the people waiting and wanting this spacecraft are a formidable bunch!

I take real encouragement from these letters and it once more has taught me why I am doing all this. So, I want to say thanks for all the expressed support and all the suggestions. I am proud to serve the AMSAT community."

(Signed) Dr. Karl Meinzer, DJ4ZC, AMSAT-DL President and Phase 3-D Project Leader.

To Karl's words of appreciation, AMSAT-NA President Bill Tynan, W3XO and Vice-President Keith Baker, KB1SF added their thanks for the very strong outpouring of support shown by AMSAT members and others in recent days. "Your comments, helpful suggestions as well as messages of understanding and support have been most helpful to us as we continue our search to find a safe and affordable launch for Phase 3-D," said KB1SF. "With such strong support within the Amateur Radio community, we can, and will make it happen!"

NASA Forms Office in Russia to Assist in ISS Preparations

NASA tells ANS it has formed the Office of Human Space Flight Programs, Russia, to oversee the transition from the Phase One Shuttle-Mir program to the assembly and operation of the new International Space Station (ISS). Astronaut Michael A. Baker will lead this office. Baker has flown four shuttle missions, including his most recent flight as commander of STS-81 (aboard Atlantis) in January 1997.

Baker will be NASA's lead representative to the Russian Space Agency and its contractors on operational issues as part of NASA's Human Exploration and Development of Space (HEDS) initiative. This places Russian liaison for all human space flight operations and initiatives under one office and consolidates preparations for the assembly of the ISS, including mission operations, crew training, logistics and technical liaison activities with Russian space organizations.

Representatives of all nations involved in the ISS have agreed to officially target a November 20, 1998 launch for the first station component and to revise launch target dates for the remainder of the 43-flight station assembly plan. Although the new dates move the launch of the first station component from June to November, the target dates agreed upon for many major station milestones during the latter portions of the five-year assembly plan are little changed. In addition, several enhancements to the station's assembly have been made, including an exterior 'warehouse' for spare parts.

The International Space Station partners have set an April 1999 target launch date for the Russian Service Module. The first station crew--Commander Bill Shepherd, Soyuz Commander Yuri Gidzenko and Flight Engineer Sergei Krikalev--will be launched aboard a Russian Soyuz spacecraft in the summer of 1999 to begin a five-month inaugural stay. Launch of the U.S. laboratory module is set for October 1999.

Full details of the current ISS assembly sequence are available in a NASA fact sheet. This fact sheet and more information on the International Space Station are available at the following URL:

70cm Commercial Interference

Reports from Guatemala indicate that commercial land mobile stations are currently being licensed in the 430 - 440 MHz band -- against International Radio Regulations. These stations may cause harmful interference to stations in the amateur-satellite service operating between 435 - 438 MHz.

Any amateur station experiencing interference from what appears to be a Guatemalan land mobile station should gather as much information as possible about the intruder including; call sign, frequency, emission type, and if possible, the content of its transmission(s). Also, note the date, time, and call signs of the other amateur station(s) you are attempting to communicate with.

Amateurs should report all of this information to your national IARU member society so that a formal complaint may be lodged through appropriate diplomatic channels.
