- MONDAY OCTOBER 16, 1989
-
- SpaceNews originates at KD2BD in Wall Township, NJ, and is distributed weekly
- around the world. It is available for UNLIMITED distribution.
-
-
- * SHUTTLE NEWS *
- ----------------
- The Space Shuttle ATLANTIS is scheduled for launch on mission STS-34 on
- Tuesday 17Oct89 at 12:57 PM ET (1657 UTC).
-
-
- * OSCAR-9 NEWS *
- ----------------
- Current information suggests that UoSAT-OSCAR-9 re-entered the earth's
- atmosphere and burned up on the morning of Friday 13th October, after over 8
- years of operation. The last telemetry received in the UK was at 2200 GMT on
- Thursday 12th October. The University of Surrey Command Station would be
- interested in receiving any telemetry taken after this time.
-
-
- * UoSAT D/E NEWS *
- ------------------
- Two weeks ago, Arianespace postponed the launch of the rocket which is to
- carry SPOT-2, UoSATs-D and -E and the four Microsats into orbit. Early this
- week, UoSAT and AMSAT teams were formally notified that the new launch date is
- 19 January, 1990.
-
- The launch delay will allow for more thorough testing of UoSAT-D and -E. This
- began on 29Sep, when engineers from the European Space Agency Technical Center
- (ESTEC) came to perform final check-out of the Transputer Data Processing
- Experiment (TDPE) and its interface to the UoSAT-E CCD camera. These tests
- demonstrated the potential complexity and flexibility of the UoSAT D/E onboard
- onboard data handling system. Ground station software was used to load TDPE
- programs as "blocks" to the standard UoSAT FORTH DIARY running on the 1802
- On-Board Computer (OBC). The OBC then loaded these programs to the TDPE using
- the Transputers' built-in serial bootloaders using the UoSAT Data Sharing
- (DASH) bus. The TDPE then commanded the CCD camera to take a picture, the
- picture was transferred from the camera to TDPE at 5 Megabits/Second, and
- finally the TDPE downloaded the image at 9600 bits/sec. to the "ground station"
- using a simple asynchronous packet format.
-
- The optics and the electronics of the UoSAT-E CCD camera were designed by
- engineers at UoSAT. The design is expected to provide Earth imaging with a
- resolution of approximately 2.7 kilometers and an image size of 740 x 960 km.
- The image is 386 pixels X 244 pixels with 8-bits of grey scale per pixel.
- Images will be transmitted on the UoSAT-E downlink to all radio amateurs,
- probably using AX.25 packet radio (generated by yet another on-board computer,
- a CMOS Z80).
-
- The mandatory flight-acceptance vibration tests were conducted this week back
- at the Royal Aerospace Establishment, and both satellites passed without
- hitch. UoSAT-D and -E are now in the clean room at the University of Surrey,
- where they will undergo nearly two months of operational tests, and provide
- testing grounds for the PACSAT and experimental software which is now under
- development at Surrey.

- * OSCAR-13 NEWS *
- -----------------
- For yet unexplained reasons, the Integrated Housekeeping Unit (IHU) on-board
- OSCAR-13 failed sometime at or near perigee between orbits 1012 and 1013.
- AO-13 command station DB2OS reported that the failure occured between 0700
- and 1000 UTC on 09Oct89. NO transponder operations are allowed until
- spacecraft operations are fully restored.
-
-
- * MIR NEWS *
- ------------
- Launch of Module-D (Service Module) is expected to take place today, 16Oct89.
- This week, Progress M-1 will undock from Mir's forward docking port and will
- be sent into a destructive re-entry. On 23Oct89, Module-D will dock with Mir
- at the forward axial port and will later transfer to one of the axial ports
- using its manipulator arm.
-
-
- * RS10/RS11 NEWS *
- ------------------
- Yes, we DO have some RS10/RS11 news this week! Rich Gopstein recently
- monitored these spacecraft and found RS10 to be active on Mode KA.
-
-
- * ARIANESPACE VIDEO *
- ---------------------
- European readers of SpaceNews might be interested to know that Arianespace
- transmits live video of their launches on Eutelsat (usually ECS 1 F2) starting
- approximately 30 minutes before scheduled launch time. The video is easily
- copied throughout Europe using a TVRO earth station having an antenna diameter
- of 1.5 meters or greater.

- Any idea when machines on the west coast at DEC will be up an running again?

- Subject: Magnetometers and magnetic storms
-
- Well, actually the subject is detecting magnetic disturbances.
-
- Decades ago W3GKP used a VERY simple means of detecting disturbances such
- as magnetic storms - as an aid to his 2-meter aurora prediction interest -
- to wit:
-
- Using a high-input-impedance voltmeter, find the grounded side of your
- telephone line. Now continue to measure or record this "zero" voltage
- relative to a good (water-pipe) ground at your location. When there is a
- disturbance from a magnetic storm your will see a voltage. He saw as much
- as a volt for big storms. When your phone rings, you may see a HUNDRED
- volts, so your meter has to be able to handle that kind of overload.
-
- The idea is that you are measuring the voltage induced in a loop of wire
- from your house back to the phone company office (with a return through
- the earth itself), induced that is by changes in the Earth's field.
-

-
- Your meter will have to have perhaps a megohm input impedance to avoid
- upsetting the phone company (if I remember what Smitty said).
-
- BTW, Smitty was one end of the first ham EME contact (with W4AO) on two
- meters. Sadly they are both now Silent Keys.

-
- Well, immediately after the quake struck, I went around the whole house to
- check for structural damage, turned off the gas, and then checked into the
- San Mateo County RACES emergency net on the WA6TOW repeater. The net handled
- a variety of reports from all over the Bay Area, such as road conditions,
- damage reports (from downed power lines to ruptured high-pressure water mains
- and buckled roads), and the like. Then it moved on to coordinating some
- Search & Rescue (search dogs and the like), emergency generators and
- Red Cross-type traffic. The net ran on into the night; I couldn't tell you
- when it shut down, because I had other things to worry about (like a father
- stuck on a train who-knows-where).
-
- Overall, the net operated in a very orderly fashion, with not much of the
- 'idiot-traffic' one might expect.
-
- One thing that surprised me was that the repeater never got knocked off the
- air; others in the area were either knocked off completely, or were in a
- very restricted mode.

- <On National Public Radio last week there was a story about baby monitors...
- The problem: Anyone with a radio scanner can hear just about every conversation
- in your house.>
-
- Monitoring these is real interesting late at night, especially since so many
- babies sleep in their parent's rooms! (Of course, this is what I've been told.
- Being a mature adult, I have no need for such titilation. :-)
-
- Seriously, it's going to be tough to get manufacturers to add any cost at all
- in this price sensitive market. I suspect encryption would double the price of
- a baby monitor. The only hope I see is if a company *concentrates* on secure
- baby monitors, since in order to sell them at the higher price, they will have
- to explain why they are better than cheaper ones, which is an issue I imagine
- the baby-monitor industry would just as soon ignore.
-
- The one that really upsets me is that the CMT lobby got EPCA pushed through
- congress to save a lousy $10 - $20 on a kilobuck device!
