Scratch two sats
by Andrew Glasbrenner 12 Feb '09

12 Feb '09

http://news.yahoo.com/s/ap/20090211/ap_on_sc/satellite_collision Iridium versus a Russian satellite, I wonder who'll get the ticket. 73, Drew CAPE CANAVERAL, Fla. - Two big communications satellites collided in the first-ever crash of two intact spacecraft in orbit, shooting out a pair of massive debris clouds and posing a slight risk to the international space station. NASA said it will take weeks to determine the full magnitude of the crash, which occurred nearly 500 miles over Siberia on Tuesday. "We knew this was going to happen eventually," said Mark Matney, an orbital debris scientist at Johnson Space Center in Houston. NASA believes any risk to the space station and its three astronauts is low. It orbits about 270 miles below the collision course. There also should be no danger to the space shuttle set to launch with seven astronauts on Feb. 22, officials said, but that will be re-evaluated in the coming days. The collision involved an Iridium commercial satellite, which was launched in 1997, and a Russian satellite launched in 1993 and believed to be nonfunctioning. The Russian satellite was out of control, Matney said. The Iridium craft weighed 1,235 pounds, and the Russian craft nearly a ton. No one has any idea yet how many pieces were generated or how big they might be. "Right now, they're definitely counting dozens," Matney said. "I would suspect that they'll be counting hundreds when the counting is done." As for pieces the size of micrometers, the count will likely be in the thousands, he added. There have been four other cases in which space objects have collided accidentally in orbit, NASA said. But those were considered minor and involved parts of spent rockets or small satellites. Nicholas Johnson, an orbital debris expert at the Houston space center, said the risk of damage from Tuesday's collision is greater for the Hubble Space Telescope and Earth-observing satellites, which are in higher orbit and nearer the debris field. At the beginning of this year there were roughly 17,000 pieces of manmade debris orbiting Earth, Johnson said. The items, at least 4 inches in size, are being tracked by the U.S. Space Surveillance Network, which is operated by the military. The network detected the two debris clouds created Tuesday. Litter in orbit has increased in recent years, in part because of the deliberate breakups of old satellites. It's gotten so bad that orbital debris is now the biggest threat to a space shuttle in flight, surpassing the dangers of liftoff and return to Earth. NASA is in regular touch with the Space Surveillance Network, to keep the space station a safe distance from any encroaching objects, and shuttles, too, when they're flying. "The collisions are going to be becoming more and more important in the coming decades," Matney said. Iridium Holdings LLC has a system of 65 active satellites which relay calls from portable phones that are about twice the size of a regular mobile phone. It has more than 300,000 subscribers. The U.S. Department of Defense is one of its largest customers. The company has spare satellites, and it is unclear whether the collision caused an outage. An Iridium spokeswoman had no immediate comment. Initially launched by Motorola Inc. in the 1990s, Iridium plunged into bankruptcy in 1999. Private investors relaunched service in 2001. Iridium satellites are unusual because their orbit is so low and they move so fast. Most communications satellites are in much higher orbits and don't move relative to each other, which means collisions are rare. Iridium Holdings LLC, is owned by New York-based investment firm Greenhill & Co. through a subsidiary, GHL Acquisition Corp., which is listed on the American Stock Exchange. The shares closed Wednesday down 3 cents at $9.28. ___ AP science writer Seth Borenstein in Washington and AP technology writer Peter Svensson in New York contributed to this report.

Maybe the peices will bump into the orbiting Shuttle tool bag and become repaired :) 73, Mark N8MH > Date: Wed, 11 Feb 2009 19:22:29 -0500 > From: "Andrew Glasbrenner" <glasbrenner(a)mindspring.com> > Subject: [amsat-bb] Scratch two sats > To: <amsat-bb(a)amsat.org> > Message-ID: <E7445281337C41719D650C3BFACEE08B@Andrewlaptop> > Content-Type: text/plain; format=flowed; charset="iso-8859-1"; > reply-type=original > > http://news.yahoo.com/s/ap/20090211/ap_on_sc/satellite_collision > > Iridium versus a Russian satellite, I wonder who'll get the ticket. > > 73, Drew >

AO-7 Mode-A beacon
by Auke de Jong, VE6PWN 11 Feb '09

11 Feb '09

Hi all, I have never witnessed the Mode-A beacon... untill now! I don't believe that it has been reported to be working for a very long time... I saw it tonight on the waterfall display on my modified Wilson CB mag-mount vertical during orbit # 56704, about 03:00UTC, for most of the pass. It did not appear to be modulated, although I could not hear it to know for sure, only by visual on the spectrum display. 73's Auke de Jong VE6PWN DO33go Edmonton, AB

Satellite Help
by Callum Graham 11 Feb '09

11 Feb '09

Hi all, Im fairly new to working satellites and I want to start using the satellites AO 7 and FO 29 as Ive not worked them before. Could anyone tell me the uplink & downlink mid passband frequencies for both satellites plese as It would make it slightly easyer for me to operate them as I find It difficult enough as Im only using a vertical antenna :-) 73.....Callum MM3YCG

Memories of Dieter, KX4Y - SK
by Keith Pugh 11 Feb '09

11 Feb '09

My memories of Dieter started during the AO-10 and AO-13 "Heydays." Dieter was living in Fort Worth at the time and working at the Comanche Peak Nuclear Plant near here. He was a regular on the "birds," our Metroplex AMSAT Net, and the Sunday afternoon 20 Meter AMSAT Net. He was a regular communications volunteer at the Soviet Space Exhibit in Fort Worth in 1991. Over the years, he was a regular member of the staff at the AMSAT Booth in Dayton. He handled all duties, but in particular, software assistance. Since he was a native German speaker, he frequently did translations for our German speaking visitors and provided valuable assistance with the development and distribution of SatPC32. Dieter assisted the author of SatPC32, Eric Eichmann, DK1TB, with problem solving and translation. Of course he attended many of the annual AMSAT Space Symposiums all over the country. Probably my favorite memory involved many others and Dieter's first visit to the AMSAT-UK Colloquium in 2004. Dieter and I had been discussing this on the 20 Meter AMSAT Net for some time and decided to meet in Edinburgh, Scotland, for a few days prior to the Colloquium. Dieter had been having regular QSOs with Ricky, GM1PLY, via IRLP, in Edinburgh, and I had never been to Scotland. Dieter and Ricky worked out the details. Ricky took us to a meeting of the Cockenzie & Port Seaton ARC to meet "the gang" and we had a very enjoyable evening along with continued communications since then. We then rode the "Flying Scotsman" train to London and on to the AMSAT-UK Colloquium. At the conclusion of the meeting, we went our separate ways; Dieter, on to Germany for a family visit, and me back to the US. Dieter also provided me with travel suggestions for a visit I made to South Africa on another trip. Dieter was an excellent example of the ideal contributor to our marvelous hobby. He constantly provided positive ideas and assistance for every phase of the AMSAT and ARISS efforts. Never complaining and always jumping in and doing what he suggested - not saying "why don't you do this." He will be truly missed by everyone and deserves a special place in Amateur Radio Heaven. 73 - Keith, W5IU

Object D
by Dave Aitch 11 Feb '09

11 Feb '09

Heard CW from Object D (?), starting at 1324 UTC. A couple of minutes after acquisition, the CW appeared to stop. The downlink signal was not strong enough to decode using my software. Are there any better Keplers ? 73, Dave. G1OCN. IO80SM.
