It was Lateran last night making that previous post and so I forgot to mention that the best and most current TLEs for Lituanicasat-1 are through Celestrak's "Cubesat" list. It doesn't appear on the Amateur list there at all (Don't understand why that is) and WA5QGD's distribution is 10 minutes early. Update your TLEs daily for this one K8YSE AA5PK and myself were only ones on this pass at 1230Z. Tom. N5HYP -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.

LO-78 passes.
by Tom Schuessler 26 Jul '14

26 Jul '14

It is unpredictable, but I suspect that LituanicaSat-1, LO 78 will be on for the morning decending (NW to SE passes on Satruday morning 7-26. In EM 12 I have a 26 degree pass starting at 1229Z. LO-78 was up for these morning passes on Wednesday and Thursday mornings but not up on any passes on Thursday late night (US time) or the Friday 124X Z pass for me this morning but was on for my 0442Z here on the 26th. On Wednesday and Thursday the only station besides myself was K8YSE/7. We never quite made it on Wednesday but completed a QSO on Thursday morning. No one else was on the bird. My 07-26 0442 pass saw no one else on the bird but myself. My observations as a purely handheld (Sometimes tripod) operator are these. The satellite is a challenge to work but provides quite nice audio when you can. As it decays, the pass times continue to shorten. They are now only 7 minutes. For us handheld guys, maybe 5 minutes of usable pass. Mid pass it really trucks across the sky. Doppler shift is quite fast as well on the 435 downlink. Published downlink is 435.1755. I start at 435.1755 so I start at 435.185 and down. 67 Hz PL and Narrow FM at 145.95 or else keep your modulation quite to avoid over-deviating. Doing so will cause the PL receive on the satellite to squelch out. Again low modulation bandwidth or talk quietly. Repeater on board has a tail so if you hit it you will hear the tone after you unkey. There is even a voice and CW ID so that makes it interesting. Satellite has hefty spin fades so that adds to the challenges. Hope to see a few additional folks to try this before it goes away.

Mars satellites' orbits changed to avoid comet tail
by Mike Lemons 26 Jul '14

26 Jul '14

When I first heard this story on the radio, I had to check the calender to see if it was April First, but it is a real story. A comet was discovered early last year coming up from below the plane of the ecliptic. It is named after the Siding Spring Observatory in Australia where it was spotted in a 20 inch scope. It is expected to pass Mars at a distance of 132,000 kilometers on October 19th. For scale, that is about a third of the distance from the Earth to the Moon. No comet has ever been recorded coming that close to the Earth. After this near-miss (George Carlin would say, near-hit), Mars will pass through the dust tail of the comet 90 minutes later. NASA and JPL want their satellites to be on the other side of Mars when this happens. http://mars.nasa.gov/comets/sidingspring/ http://news.sciencemag.org/physics/2014/07/comet-fireworks-mars http://mars.nasa.gov/news/whatsnew/index.cfm?FuseAction=ShowNews&NewsID=1675 http://www.jpl.nasa.gov/news/news.php?release=2014-244 Mike KI6ADN

Lituanicasat-1 was not heard on the 1245utc pass over the SW United States. It was on for that pass yesterday and N5HYP was worked from DM43. The current keps had it at 234KM. 73, John K8YSE/7
