STS-76 docked with the Mir space station on 24 March 1996. Shannon Lucid was left on Mir for an extended stay on the first NASA Mir mission.
On September 19 STS-49 Atlantis docked with the Russian Mir space station. Aboard Atlantis in the payload bay were the Orbiter Docking System, the modified Long Tunnel, and the Spacehab Double Module, containing supplies for the Mir. Astronaut John Blaha relieved Shannon Lucid as NASA resident on the complex. Atlantis undocked from the Mir complex on September 23 at 23:33 GMT. Valeriy Korzun, Aleksandr Kaleri and John Blaha remain on Mir. On September 26 Atlantis closed its payload bay doors, and at 11:06 GMT fired its OMS engines for a three minute long deorbit burn. After entry interface at 11:42 GMT the spaceship flew across Canada and the US for a landing at the Kennedy Space Center's Runway 15 at 12:13 GMT.
AKA: Atlantis; STS-76 (Lucid).
First Launch: 1996.03.22.
Last Launch: 1996.09.26.
Duration: 188.17 days.
Mir: The passes of Mir for our area take place during the night hours and so there is not much to report about the life on board. Module Priroda: The launch of this module has been put back again. Latest available planned launch date: 23.04.1996. Chris v.d. Berg, NL-9165/A-UK3202
The first operation will be the launch of the module Priroda. The Russians want to launch this module on 23.04.1996, but further delay might be possible. In fact all is ready for that launch, but specialists responsible for the power supply of that module want to be sure that the accumulators are fully reliable if unexpected the Priroda has to fly longer than the estimated period between launch and docking. The Priroda has not been equipped with solar panels and if the accumulators show failures there are no alternatives. That is why the experts responsible for the power systems and energy consumption take more time for tests. The dates for some important operations can be set only after the launch and successful docking of Priroda and the redocking thereafter. Priroda has to dock to the forward axial port (-X axis) and will be repositioned from there to the radial port (+Z axis). After this the date for the launch of the freighter Progress-M31 can be determined.
2d Spacewalk (EVA) 21st Main Expedition Mir: Possibly this operation will be executed in May this year. The cosmonauts will have to transfer one of the solar panels which have been brought to Mir by Atlantis (STS-74) and who are still attached at the outer surface of the Docking Compartment (SO - so not Docking Module. SO stands for 'Stykovochnyy Otsek'). They will have to transfer that solar panel to the astrophysical module Kvant-1 (Module-E). During this operation they will use the 2d Strela, which they installed during their first EVA. With this 2d Strela-crane they have the possibility for movements between the SO and the Kvant-1. Originally the Russians planned to install on Kvant-1 the solar panel which is still at the outer surface of the Kristall-module, but they preferred the installation on Kvant-1 of a brand new one. The Russians hope to accomplish this task during that 2nd EVA, but they are ready to insert a 3rd EVA if necessary. The solar panels which have been brought to Mir on the outer surface of the SO will not be deployed from there, but will be used on parts of the Mir-complex.
VDU: This abbreviation stands for External Engine Installation. This is the box, which can be seen in the top of the long Sofora mast which has been erected on Kvant-1. Nobody was sure about the use or the usefulness of that engine. In an interview Thomas Reiter told me that this VDU often is used for the orientation of the complex during periods in which the gyrodynes have to be silenced for repositioning. These gyrodynes cannot turn through 360 degrees and so now and then repositioning is necessary. There is a problem for the future: when the fuel of the VDU has been spent refuelling will not be possible. Perhaps the Russians hoped that fuel would be sufficient for the VDU at least until the end of the operational life of Mir in 1997 or 1998. So if they want to prolong the use of Mir by some years they will have to find a way to refuel that VDU or to install a new one.
Chris v.d. Berg, NL-9165/A-UK3202.
Priroda: The module for remote sensing Priroda is also known as TsM-I and 77KSI. In space Priroda has a mass of 19.5 tons. The mass of the payload is 10.5 tons, among which 1.2 tons as a supplement for the equipment of the Mir-complex, the remote sensing equipment has a mass of 4.7 tons and Priroda can transport 1.8 tons cargo. The original planning foresaw in a solar array in the front of Priroda (axial), but the place of the array is now used for the installation of extra equipment and experiments. So during the autonomous flight Priroda has to depend on the nickel cadmium accumulators for her power supply. Priroda must have an active lifetime of more than 3 years.
Cargo: Priroda will also deliver additional equipment to the Mir station, experiments for Shannon Lucid and the SAFEX-2 transceiver for radio-amateur activities.
Chris v.d. Berg, NL-9165/A-UK3202.
During the first day the flight went well, all systems functioned normally. On 24.04 two orbit corrections will be executed to bring Priroda in a higher orbit. This will also be done on 25.04. After the corrections on 25.04 the orbit must have an apogee of 404 KM and a perigee of 358 KM. On docking day (26.04) the last 2 orbit corrections will take place.
Estimated day/time of docking:
On 26.04.1996 at 12.43.00 UTC. So the soft docking (Kasaniye) will take place just a few minutes after LOS of both objects for our position during the first pass over here in Mir's orbit 58195 and Priroda's orbit 48. So there might be traffic from Mir about the approaching Priroda between 1233-1238 UTC. Undoubtedly the Russians will use the eastern geostationary satellite (Altair-2 on 96 dgs East) for communications, but mostly during such operations traffic can also be monitored on VHF. Possibly it might be worthwhile to monitor Mir/Altair-1 windows in the period before approach and docking.
Repositioning of Priroda: If the docking on 26.04.1996 will be successful the repositioning of Priroda will take place on the next day, 27.04.1996. Priroda will be repositioned by a manipulator arm (the Lyappa) from the forward port of the transition section (P.Kh.O.), -X axis to the radial port of that section, +Z axis.
Progress-M31: The launch date of this freighter depends on the docking- and repositioning operations with Priroda. If this all goes according to plan Progress-M31 will be launched on 8.05.1996.
Safex-2: In fact this complete radio-amateur station has been installed in Priroda and does not belong to the cargo transported by that module. For this radio station 3 antennae have been installed on Priroda.
Chris v.d. Berg, NL-9165/A-UK3202.
On 27.04.1996 at 0800 UTC Priroda will remove itself with a manipulator arm (the Lyappa) to the +Z axis. After that operation the airseal can be checked before the opening of the hatches. The repositioning will take place out of our range.
A part of the cargo of Priroda consists of biological experiments for the production of clean medical preparations and 900 KG equipment and experiments for the American astronaut Shannon Lucid. Priroda has been equipped by a lot of equipment for scientific research of the earth (all kinds of devices and camera's for remote sensing) and the atmosphere.
Chris v.d. Berg, NL-9165/A-UK3202.
Power supply problems: Radio traffic during 27, 28 and 29.04.96 revealed that the cosmonauts worked on problems regarding the power supply of Priroda. After the redocking Priroda will get power from the S.E.P. (power supply system) of the Mir complex.
Chris v.d. Berg, NL-9165/A-UK3202.
Spacewalk (EVA): It might be possible that the 2d EVA of the crew of the 21st Main Expedition to Mir will be put forward too. The date 8.05 has been mentioned, but the exact date still has to be determined.
Priroda: The repositioning of this module on 27.04. took place between 0830 and 0920 UTC, so considerably shorter than originally reported.
SAFEX-2: This radio-amateur station on board Priroda cannot be used before the Priroda is unpacked and fully operational.
Chris v.d. Berg, NL-9165/A-UK3202.
On the 2d day of the flight again signals from Progress-M31's transmitters.
Docking Progress-M31: On 7.05.1996 at 08.54.17 UTC Progress-31M docked automatically at the forward axial docking port of the Mir-complex (-X axis). During the first pass over here of both objects in orb. 58364 (1016-1026 UTC) Onufriyenko could be heard reporting data of the approach. He was following the approach on the screen of the TORU (remote guidance from the inside of Mir) monitor. He was ready to take over the guidance if necessary or ordered by TsUP. On the screen he could see the docking port where Progress-M31 had to dock.
Opening of the hatch: Already during the next pass in orb. 58365 they accomplished the airseal checks and opened the hatch at 10.25.11 UTC, so within our range.
Cargo: This has a mass of 2410 KG and consists of the normal cargo delivered by Progresses: water, fuel, letters, equipment, repair material etc.
Spacewalk (EVA): The next EVA of this crew is on schedule for 18 or 19.05.1996.
Chris v.d. Berg, NL-9165/A-UK3202.
Chris v.d. Berg, NL-9165/A-UK3202.
Radio traffic between the cosmonauts and Sannon Lucid who kept watch on board Mir went via the normal VHF-frequencies and was relayed via the geostationary satellite Altair (Kosmos-2054) on 16 dgs West. Shannon assisted the cosmonauts during the putting on and off of their spacesuits. During the EVA she took care for the systems of the space station and the communications.
3d EVA: This is on schedule in the night from 24 to 25.05.96. Opening of the hatch on 24.05 at 2050 UTC, closing of the hatch on 25.05.96 at 0205 UTC. During this EVA the cosmonauts will deploy, connect and test the solar panel on Kvant-1.
Chris v.d. Berg, NL-9165/A-UK3202
4th EVA: This EVA is on schedule for 30.05.1996 between 1900-2100 UTC. Main task will be the transfer of the MOMS (opto-electronic stereo scanner) to the outer surface of the Priroda module and the installation of this device over there. The MOMS has been delivered to Mir as a part of the cargo of the Priroda. Apart from this work they will also have to accomplish some minor tasks.
Chris v.d. Berg, NL-9165/A-UK3202.
6th EVA Onufriyenko and Usachov:
This EVA will take place on 13.06.1996. Times not decided yet. During this EVA the cosmonauts will install Ferma-3 (a girder or truss construction) at the outer surface of the astrophysical module Kvant-1. Experience with constructions like these are very important for the future. They will be used for the building and exploitation of the International Space Station Alpha.
Chris v.d. Berg, NL-9165/A-UK3202.
6th EVA: Still on schedule for 13.06.96. Times not yet decided. Task: Installation of the Ferma-3 girder construction at the outer surface of the astrophysical module Kvant-1.
Chris v.d. Berg, NL-9165/A-UK3202.
Chris v.d. Berg, NL-9165/A-UK3202.
Soyuz-U: Within the period of some weeks 2 launches of reconnaissance satellites with the carrier Soyuz-U failed. The first time this was on Baykonur on 13.05. 49 seconds after lift off the payload fairing came loose and the control-system gave the command for self-destruction. The commission to investigate the accident failed to find a unanimous conclusion. 4 different possibilities had been suggested even the rather bizarre idea that a big bird collided with the rocket. Normally all launches of analogue rockets are suspended until the experts know for sure the cause of the accident. This time they did not wait until a definite conclusion and launched another spy-satellite, now from Plesetsk using the rocket Soyuz-U. And again exactly after 49 seconds the fairing came loose and rocket and satellite were destroyed. This time the commission started a thorough investigation, which is still going on. So possibly the launch of the freighter Progress-M32 will be put back again.
Mir-routine: Life goes on: the 2 Russians and Shannon Lucid are still in a very good mood. They do not seem to worry about the 'rocket' problems. The relief crew for Onufriyenko and Usachov has to fly with the Soyuz-TM24 on 14.08.1996. This crew consists of the Russians Manakov and Vinogradov and de French cosmonaut Claudie Andree-Deshays. For this launch a modified rocket, the Soyuz-U2 is needed. Financial problems might put a spoke in the wheel. During the last week Shannon Lucid worked with the Glove box. She met some problems with contacts and switches but resolved these by the help of an expert at TsUP Moscow. Shannon Lucid will be relieved by John Blaha during the 4th Shuttle-Mir docking mission STS-79 by Atlantis in the beginning of August.
Chris v.d. Berg, NL-9165/A-UK3202.
Soyuz-TM24: Shannon Lucid also said that the Russians still stick to the launch of this ship on 14.08.1996 with Manakov, Vinogradov and Claudie Andree-Deshays and the return of Onufriyenko and Usachov together with the French guest-cosmonaut on 30.08.1996 with the Soyuz-TM23. So possibly Lucid will be in the Mir-station during the mission of Andree-Deshays.
Progress-M32: If there will be permission for the use of the rocket Soyuz-U before 21.07.1996 this freighter will be launched from Baykonur in the night from 21 to 22.07.1996.
Just before the deadline for this report the press-service of TsUP near Moscow did not have information about changes and sticks to the original schedule: Launch Atlantis: 31.07.1996, Launch Progress-M22: night from 21. to 22. 07.1996, and Launch Soyuz-TM24: 14.08.1996.
Moscow confirmed that changes might be possible.
Chris van den Berg, NL-9165/A-UK3202
Progress-M32: Still to be launched in the night from 21 to 22.07.96.
Soyuz-TM24: The ship will have to bring the relief crew and the French cosmonaut to the Mir-station. Soyuz-TM24 with a crew of 3 persons will be launched by the use of the rocket Soyuz-U, so not with the more powerful Soyuz-U2. To enable Soyuz-TM24 to have a rendezvous with Mir after being launched with a Soyuz-U rocket , the Mir-station had to be brought in a lower orbit. The engines of the Progress-M31 corrected Mir's orbit on 2 and 4.07.96.
Radio-amateur traffic: Now and then phone from Mir on 145.550 mc. That what is needed for Packet radio traffic is always in use for service traffic on 143.625 mc. The downlink signals of the Mir-station only give the P/R confirmation (R0Mir-CUP). The transmitter of Safex-2 in the Priroda-module can be heard in a recorded greeting in Russian and English on 437.925 mc, FM-N. This frequency is also in use as a primary frequency for ISM-purposes (Industrial Scientific and Medical), which means that there might be a lot of interference if that frequency is in use for ISM by local stations, for instance hospitals.
Chris v.d. Berg, NL-9165/A-UK3202.
Soyuz-TM24: The intention still exists to launch this ship with the crew of the 22d Main expedition to Mir (Manakov and Vinogradov) and the French cosmonaut Claudie Andre- Deshays on 14.08.1996, but a final decision has not yet been made. It might be possible that the Russians entrust the launch of the unmanned Progress-M to the carrier Soyuz-U, but wait with the green light for the use of that carrier for a manned ship until the eventual successful launch of the freighter.
Chris v.d. Berg, NL-9165/A-UK3202.
Progress-M32 has to link up with Mir at the forward axial port (-X axis). The first approach will be in the automatic mode by the system Kurs. The crew has to be ready to use the TORU (Tele-operating Guidance regime). If the automatic approach will fail the first time the crew will control the approach the next day using TORU. During the pass in orbit 59500 from 0918-0930 UTC today the crew got instructions about this operation.
During the flight signals from Progress-M32 can be monitored in the 166, 165 and 922 MC bands.
Chris v.d. Berg, NL-9165/A-UK3202.
Chris v.d. Berg, NL-9165/A-UK3202..
Towards the planned launch time (24.07 at abt. 2247 UTC) the Mir station was in visual range of Baykonur and the crew hoped to see the start. So they did not see anything and during the pass in orbit 59591 (0500-0512 UTC) Onufriyenko asked TsUP why the launch has been postponed.
Meanwhile the cosmonauts continue the preparations for the departure of the freighter Progress-M31, still docked to the station. They are loading the Progress-M31 with things they do not longer need . Progress-M31 remains docked at the station until the 2d day of the flight of Progress-M32 when it is obvious that the systems of that freighter are functioning normally.
Soyuz-TM24: About this ship with the relief crew Manakov and Vinogradov and the French spacionaute Claudie Andre-Deshays there will be a press-conference in Ts.P.K. (Starcity) on 26.07.1996. Undoubtedly the failure of the Soyuz-U rocket will be discussed there and we hope to get information about the eventual launch of Soyuz-TM24 on 14.08.1996.
Chris v.d. Berg, NL-9165/A-UK3202.
The estimated docking time of Progress-M32 at Mir: 2.08.1996 at abt. 2159 UTC.
Soyuz-TM24: The launch of this ship with the relief crew and the French spacionaute is now on schedule for 20.08.1996. We hope to get an eventual confirmation or additional information by CNES during this week.
Chris v.d. Berg, NL-9165/A-UK3202.
If all continues to go according to plan the Progress-M32 will link up with Mir on 2.08.1996 at 2158 UTC. The first pass (of that sequence) of Mir and Progress-M32 in Mir's orbit 59727, will last from 2147 until 2154 UTC. So during this pass the final approach is going on and radio communications regarding this operation possibly can be monitored in the VHF-band.
The Progress-M32 will deliver to the Mir-station a cargo of 2478 KG. 328 KG of this cargo consists of experiments and equipment to be used by the French spacionaute Claudie Andre-Deshays during her Cassiopeia mission to Mir this month. The cargo further consists of water, food, fuel, oxygen, letters, equipment, software, spare parts etc.
Progress-M31: This freighter is still docked at the forward (-X axis) port of the Mir-station and this port has to be free for the arrival of Progress-M31's successor Progress-M32. For that reason Progress-M31 will separate from Mir on 1.08.1996 at 1642 UTC and after a short autonomous flight this freighter will be put on a destruction course and burn up in the atmosphere over a designated area of the Pacific East of New-Zealand.
Chris v.d. Berg, NL-9165/A-UK-3202.
Progress-M32 docked at the Mir-station (-X axis, forward port transition section) on 2.08.1996 at 22.03.44 UTC. So 6 minutes later than planned. Approach and docking were executed in the automatic mode by the use of the system Kurs.
Radio traffic: As always during such operations the radio traffic was very interesting. During the pass in orb. 59727, 2149-2156 UTC , the approach was still going on. The crew just accomplished a test of the TORU-system (for eventual manual guidance by the Mir-crew). They did not use this system. At 215520 UTC the distance between Progress-M32 and Mir was 180 M. The cosmonauts monitored the images made from Progress-M32 of the station on their displays. They also observed the approaching Progress-M32 via illuminators. The traffic revealed that, though somewhat slower than planned, the operation was proceeding well. During the next pass in orb. 59728, 2327-2333 UTC, radio traffic revealed that Progress-M32 had docked at Mir. The preparations for the opening of the hatches were going on, i.e. airseal checks, the equalisation of the pressures in Progress-M32 and Mir, deployment of an air hose, and so on. During the pass in orb. 59729, on 3.08.1996 from 0057-0107 UTC, the hatches were open and de cosmonauts already had entered the freighter to remove things which had to be transferred to the complex as soon as possible. After checks of the systems of Progress-M32 and the work to be sure that Progress-M32 was fixed at the station tight and safely the crew could go asleep. And so did, tired but satisfied, your 'observer'.
The Progress-M32, will -relatively- remain a part of the Mir-complex for a short period: If the operations with Soyuz-TM24 (relief crew) will proceed according to plan (of this moment) Progress-M32 has to depart on 20.08.1996 to free the forward docking port for the Soyuz-TM24, which has to be launched on 19.08.1996. Progress-M31: This old freighter separated from Mir on 1.08.1996 at 16.44.54 UTC. and burnt up in the atmosphere. (Further details in a next Mir-report.)
Chris v.d. Berg, NL-9165/A-UK3202.
Launch of Soyuz-TM24: The launch of this ship with the above mentioned crew members has been put forward and will now take place from Baykonur on 17.08.1996 at abt 1317 UTC.
The service call sign of the crew is FREGAT, so resp. Fregat-1. -2 and -3).
The names of the new crew and the earlier launch date had been given by a recorded message of Shannon Lucid transmitted from Mir on 437.925 mc.
Progress-M31: As already has been reported this freighter ceased her existence on 1.08.1996. The exact times of this operation were: Separation from Mir: 16.44.45 UTC, start reentry burn: 19.44.30 UTC and burning up over a designated area in the Pacific East of New Zealand: 2033 UTC.
Progress-M32: This freighter is still docked at Mir. If the launch and first part of the flight of Soyuz-TM24 will proceed as planned Progress-32 will undock from Mir on 18.08.1996 and burn up in the atmosphere.
Chris v.d. Berg, NL-9165/A-UK3202.
Progress-M32: This freighter will separate from Mir on 18.08.1996 at 0931 UTC. In contradiction to the supposition in MirNEWS.321 Progress-M32 will not be brought on a destruction course, but stay in orbit in an autonomous flight. The Progress-M32 will redock to Mir after the departure of Soyuz-TM23 with the relieved crew. The redocking has to take place on 3.09.1996. Progress-M32 will be used to reboost the Mir-complex in the original somewhat higher orbit after the return to earth of Atlantis (STS-79) in September.
Chris v.d. Berg, NL-9165/A-UK3202.
On Feb 7 at 16:28:01 GMT the EO-22 crew and American astronaut Linenger undocked the Soyuz TM-24 ferry from the front docking port, flew it around to the far side of the complex and redocked at the rear Kvant port at 16:51:27 GMT. This cleared the forward port for the arrival of the EO-23 crew, who brought with them German astronaut Reinhold Ewald on Feb 12.
Progress-M32: This freighter separated from Mir on 18.08.1996 at 0934 UTC. The autonomous flight of the Progress-M32 will last until 3.09.1996.
Soyuz-TM23: Return to earth of relieved crew of ME 21 (Onufriyenko and Usachov) and Claudie Andre-Deshays with the Soyuz-TM23 has been put back until 2.09.1996.
Chris v.d. Berg, NL-9165/A-UK3202.
Soyuz-TM23: This ship will return to earth on 2.09.1996 with the relieved crew of ME 21 and Claudie.
Progress-M32: This freighter is flying in a somewhat higher orbit than Mir. Progress-M32 will redock at Mir on 3.09.1996.
Chris v.d. Berg, NL-9165/A-UK3202.
0110 UTC: The hatch behind the departing cosmonauts was closed.
0417 UTC: Soyuz-TM23 separated from Mir to begin a short autonomous flight.
The aimed landing position was in a distance of 107 KM from Tselinograd in Kazakhstan with an estimated landing time of 07.41.03 UTC. (So they landed 37 sec. later in another position).
Progress-M32: This freighter is still flying autonomously. Redocking to the Mir complex is on schedule for 3.09.1996 at abt. 0755 UTC.
Chris v.d. Berg, NL-9165/A-UK320.
(So in a relative short period the Russians successfully accomplished crucial operations. As far as Russian spaceflight is concerned Aleksandr Lebedj has nothing to worry about!!)
Chris v.d. Berg, NL-9165/A-UK3202.
Atlantis (STS-79): If all goes according to plan and Atlantis starts on 16.09.1996 at 0854 UTC radio-amateurs in Western-Europa can try to monitor phone reports from Atlantis at abt. 20 minutes after launch. This might be possible during the first contact of Atlantis via a relay-facility in Spain. During the last flight of Atlantis signals could be monitored on 259.700 mc AM. After an elapsed time of 2days 18hrs 23mins Atlantis must link up with Mir, so if the launch goes as planned and the flight has been proceeding well this will take place on 19.09.1996 at 0017 UTC (for the USA still 18.09). If the same communications are used as during the last Atlantis mission an American TDRS as well as a Russian Altair (1 or 2 or both) will be used during approach and docking. 23 minutes after the 'soft docking' the so called 'hardmate' will take place. After a check period of 2hrs and 25mins the hatches will be opened.
Radio-amateurism: During the last week a lot of traffic, Packet Radio and Phone could be heard on 145.550mc. Korzun is an enthusiast radio-amateur and he made a lot of QSO-s over Western Europe. His knowledge of the English language and his feeling for radio-amateurism enables him to do this and to enjoy it. Apart from some recorded voice messages on 437.925mc I cannot say much about the use of the Safex-2 facilities in the Priroda module. Here the UHF-frequencies 437.925, 437.950 and 437.975 mc are used for medical purposes (hearth monitoring) by a hospital nearby. Monitoring these frequencies is such a torment that it would endanger the condition of my hearth in such a way that I myself even might need that service by that hospital!
Chris van den Berg, NL-9165/A-UK3202.
Rendezvous and docking operations:
Begin Mir rendezvous operation: 18.09 2134 UTC TI Burn 19.09 0003 Arrival on R-bar (Earth radius vector) 0153 Hovering at 170 feet from Mir 0235 Begin final approach 0310 Atlantis docks with Mir 0317 Hardmate Atlantis/Mir 0337
For observers in Western-Europe the passes of Mir (and -the then being in a short distance- of Atlantis) begin during Mir's orbit nr. 60468 with a pass between 0307-0315 UTC, maximum elevation 11 degrees. So communications between Mir and Atlantis might be possible on the well known VHF frequencies. Whether there will be TV-images -for instance via CNN- or not is not sure at this point. If the Russians use Altair-1 (Cosmos-2054) over 16 dgs West images seen by Mir of the approaching Atlantis might be possible between 0230-0324 UTC. During the last docking mission of Atlantis (STS-76) those images could be seen via CNN together with images of Mir seen by a camera in Atlantis. It is also possible that the Russians will use Altair-2 (over 96 dgs East) during the window from 0306-0402 UTC.
Chris v.d. Berg, NL-9165/A-UK3202
SAREX STS-79: During this mission there might be radio-amateur activities by the astronauts-radio-amateurs Jay Apt (N5QWL), Carl Walz (KC5TIE) and John Blaha (KC5TZQ). Sarex VHF downlink is 145.840 mc FM with uplink frequencies: 144.450 and 144.470 mc FM. Please do not use 145.840 mc FM for 'uplink' or -during Atlantis passes -local bragging. Chris v.d. Berg, NL-9165/A-UK3202
