Shuttle's So CA Connection
by Clint Bradford 05 Jul '11

05 Jul '11

When the nation’s last space shuttle blasts off from Cape Canaveral, Fla., on Friday, it will mark the beginning of the end of a four-decade-long program steeped in American ingenuity. In an article in today's Los Angeles Times newspaper, there's a look at the shuttle program's high technology and its lasting imprint on Southern California’s economy. Work on the shuttle program began in 1972 as the Apollo moon landings were coming to an end. The shuttle program marked a new era in human spaceflight and called for a quantum leap in space technology, as the article says ... Before the shuttle, astronauts reached space by squeezing into a small capsule launched atop a massive rocket. By the time the shuttle was in design, the space program was looking for ways to keep as many as seven astronauts in orbit for weeks at a time in relative comfort. To do this, scientists and engineers had to rethink nearly every aspect of the endeavor, notably flight controls, rocket engines and protection from searing heat generated by reentry. Along with the story, there’s an interactive graphic that showcases some of the California companies that built parts of the shuttle. There’s also a photo gallery with historic pictures of the shuttles and three panoramas of Pratt & Whitney Rocketdyne’s rocket engine assembly plant. The countdown has begun for the last space shuttle, Atlantis, which is slated for launch Friday at 8:21 a.m. Pacific time. If you’re interested, you can watch the shuttle launch on NASA’s website.

Hello Everyone, If we waited for the weekend ANS news cycle this information would be too late. Posted in ANS-184: + AMSAT has received the sad news of the death of Leanore Guimont, KA6UCD, the wife of Dave, WB6LLO. For many years no Symposium would be complete without the Dave and Leanore "jewelry" contest. Our thoughts and prayers go out to Dave. He has requested no cards or email be sent. AMSAT has received this update for those of you in the area: The services for Leanore are being held at St David's Episcopal Church in San Diego on Saturday July 9 at 1000. -- 73 de JoAnne K9JKM k9jkm(a)amsat.org Editor, AMSAT News Service

question about the Space Station
by George and Cheryl Abbott 05 Jul '11

05 Jul '11

Hi All:I observed the Space Station pass over this location(Hopkinton,RI) a couple of nights ago.The sky was relatively clear at the time.However,I observed a slight wobble( >.05 degrees ) as it passed from NNW to SSE.I have observed multiple Space Shuttle passes and I have never observed any wobbles in its orbit.Is the Space Station having any troubles with its gyroscopes?Could atmospheric conditions or the way it reflects sunlight explain my observation?Comments welcome!

VUCC Satellite #217
by Jeff Yanko 05 Jul '11

05 Jul '11

Hi all, After 159 days since submitting the paperwork and couple follow up e-mails, I finally received my VUCC Satellite award. For some reason, I keep thinking I should've received some paperwork with the certificate and stickers. I thought they were suppose to have a copy of the grids already worked on a paper format. Maybe I'm thinking of something else. If anybody knows this to be true, please let me know. Maybe this wait isn't quite over yet. 73, Jeff WB3JFS

I am not sure of what you are looking at to get a prediction, however, if you are using SATPC32 and you have setup the observer as yourself at the location you list, you will have the correct times UTC for your location. The program can be setup to show in local time or UTC. 99.9% of hams learn what their local time is with reference to UTC since all contacts and space referenced items are in UTC. Yes, your time would be 7hrs difference on the west coast. Good luck on tracking the birds-don't forget to update your keplerian data to keep the positions of the satellites current. 73, Dee, NB2F >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Message: I have aquestion about the AOS Acquition of Signal UTC time. Is the UTC time that is stated for a predicted pass, the local time that the bird will pass over my position? Or do I have to subtract 7 hours from the UTC time to get the correct time the bird will pass over my position in Riverside, CA?

Linear Sats
by Kevin Deane 05 Jul '11

05 Jul '11

>Show me an all-mode HT that retails for the same sort of price and is the same sort of size as an FM HT and I might be interested. Otherwise, to get >UHF and VHF SSB I'm stuck with an inconveniently large radio which is only really useful for the twenty minutes a day that a satellite is overhead. >Not to mention the difficulty involved in tuning the radio and aiming the antenna. Doesn't the Doppler shift mean you need to constantly retune? >How do you manage to do that, key the mike and point the aerial, *and* have enough brainpower left to make a contact? I would love the opportunity to have the "difficulty" of tuning in the big boy sats! I would also find pletny of uses besides the sats for a radio of that caliber...And one of these days I will gladly spend the money on the biggest badest radio I can find and then I will build the biggest bestest tower ever with a rediculous amount of elements and rotater dealy bob!!! So there! Kevin KF7MYK

ARISSat-1 Deployment Possibly Delayed
by Clint Bradford 04 Jul '11

04 Jul '11

FROM the press office of Roscosmos: Alexander Samokutiaev, flight engineer of the International Space Station’s expedition 28, informed about the planning for the upcoming Russian EVA in his blog in Roscosmos web. According to Russian cosmonaut, the EVA is slated for August, pending the launch of the shuttle scheduled for July 8. Alexander will work outside the ISS with his colleague Sergey Volkov. The cosmonauts are to perform several ISS RS refurbishing tasks, as well as to launch small satellite Kedr. Russian cosmonauts onboard the International Space Station switched on small spacecraft Kedr on April 12, in order to commemorate the jubilee of Yury Gagarin’s mission. Small spacecraft Kedr developed under the RadioSkaf experiment bears the name adopted by Yu.A. Gagarin call sign in his historical flight, namely Kedr. The satellite’s signal will be transmitted at radio amateur frequency of 145.95 MHz. Kedr has radio amateur call sign RS1S. RadioSkaf is implemented in the framework of UNESCO’s student space education program. Kedr will transmit different signals, images, including the talks of famous Russian scientist Kostantin Tsiolkovsky, rocket Chief Designer Sergey Korolev conversation with the first cosmonaut during his 108-min historical mission, and famous Gagarin’s “Go!” (Poekhali!), of course.
