[amsat-bb] TACSAT 3 Question
Is anyone else if having trouble with 'TACSAT 3' When I try to track it with SATPC32 it throws an error. The error message is in German. thanks W9KE tom ... ___ Sent via AMSAT-BB@amsat.org.

Tom, According to Space Track, TACSAT 3 reentered April 30th. The final Keps will normally have huge values for drag, etc which may break the standard predictive calculations. 73s, Alan WA4SCA TIP Reports for Object 35001, TACSAT 3, (Decayed 2012-04-30), US Report Date/Time2012-05-01 00:10:00 GMT Predicted Decay Time2012-04-30 20:04:00 GMT +/- 15 Minutes Predicted Decay Location40.2° S, 110.8° E Direction ascending Inclination 40.4° Revolution Number 16700 High Interest ObjectN Final Report ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: TACSAT 3 Question
Bob and Alan, There must be a better way to detect re-entry than simply than throwing an unhandled exception. You guys seem to be the experts - any suggestions on how to do it ? It seems to be related to the BSTAR drag value. Some say when the BSTAR drag value gets too high the sat has re-entered or is about to re-enter. The recent chicken little contest peaked my interest in this topic. So far no one has offered the magic value for too high. Not looking for the obvious answer - it is too high when SatPC32 throws an exception. Paul Williamson's NASAWASH would be a good starting point. Check the keps for problems and errors before posting them. The tracking program could also check for the problem values. Neither of these would be difficult if the the value of too high was known. Would you have to look at the other elements or is BSTAR enough. thanks, W9KE tom On Fri, May 11, 2012 at 10:42 AM, Robert McGwier rwmcgw...@gmail.comwrote: You mean other than that it has reentered?

[amsat-bb] Revised NASA TV Coverahe
MEDIA ADVISORY: M12-084 UPDATED COVERAGE FOR NASA/SPACEX LAUNCH AND MISSION TO STATION CAPE CANAVERAL, Fla. -- The second SpaceX demonstration launch for NASA's Commercial Orbital Transportation Services (COTS) has been rescheduled for a liftoff on Saturday, May 19. The launch of the Falcon 9 rocket carrying a Dragon capsule will occur from Space Launch Complex 40 at the Cape Canaveral Air Force Station in Florida. There is a single instantaneous launch opportunity at 4:55 a.m. EDT. NASA Television launch commentary from Cape Canaveral begins at 3:30 a.m. During the flight, SpaceX's Dragon capsule will conduct a series of check-out procedures to test and prove its systems, including the capability to rendezvous and berth with the International Space Station (ISS). The primary objectives for the flight include a flyby of the space station at a distance of approximately 1.5 miles to validate the operation of sensors and flight systems necessary for a safe rendezvous and approach. The spacecraft also will demonstrate the ability to abort the rendezvous. Once these capabilities are successfully proven, the Dragon will be cleared to berth with the space station. FALCON 9 LAUNCH PAD PHOTO OPPORTUNITY Friday, May 18 (L-1 day): A photo opportunity of the Falcon 9 rocket and Dragon capsule on the launch pad will be available for the news media. Spokespeople from SpaceX will be available to answer questions. Media will depart from NASA's Kennedy Space Center Press Site by government bus at 9 a.m. for Space Launch Complex 40. Media will be returned at approximately 11 a.m. SpaceX security regulations require that media attending this event be U.S. citizens. REMOTE CAMERA SETUPS Friday, May 18 (L-1 day): Media will be able to establish sound-activated remote cameras at the launch pad. The location is within Space Launch Complex 40 on the east side of the pad inside the perimeter fence. Media who want to participate in remote camera setup will depart from Kennedy's Press Site by government bus at 9 a.m. in association with the launch pad photo opportunity and will be returned to the press site separately after remote camera set-up is complete. SpaceX security regulations require that media participating in this activity be U.S. citizens. PRELAUNCH AND POST-LAUNCH NEWS CONFERENCES Friday, May 18 (L-1 day): The prelaunch news conference for the NASA/SpaceX launch will be held at the Kennedy Press Site at 1 p.m. NASA Television will provide live and streaming Internet coverage. Participants in the prelaunch news conference will be: - Phil McAlister, Acting Director, NASA Commercial Spaceflight Development - Alan Lindenmoyer, Manager, NASA Commercial Crew and Cargo Program - Gwynne Shotwell, President, SpaceX - Joel Tumbiolo, Launch Weather Officer, 45th Weather Squadron, Cape Canaveral Air Force Station Media representatives can participate in the news conference in-person at Kennedy or via a phone bridge by calling NASA's Johnson Space Center newsroom at 12:45 p.m. at 281-483-5111. Saturday, May 19 (Launch day):A postlaunch news conference will be held at Kennedy's Press Site at approximately 8:30 a.m. Audio of the launch and the prelaunch and postlaunch news conferences also will be carried on the NASA V circuits, directly accessible by dialing 321-867-1220, 1240, 1260 or 7135. The briefings will be streamed live on the agency's website. Saturday, May 19 (Launch day): A delegation from the Student Spaceflight Experiments Program (SSEP) will be at the Kennedy Press Site and available for interviews and experiment demonstrations between 3 and 4:30 a.m. The students represent three of the experiments that will launch aboard the SpaceX Dragon as part of the International Space Station NanoRacks 9 platform. A sign-up sheet will be available in the newsroom for those media representatives wanting to talk to the students. For information on the Student Spaceflight Experiments Program: http://go.nasa.gov/INLqjT NASA TV LAUNCH COVERAGE Saturday, May 19 (Launch day): NASA TV live coverage begins at 3:30 a.m. and concludes at approximately 5:30 a.m. On launch day, mission audio, the launch conductor's countdown activities without NASA TV launch commentary, will be carried on 321-867-7135 starting at 8 a.m. Launch information also will be available on local amateur VHF radio frequency 146.940 MHz, heard within Brevard County. NASA TV MISSION COVERAGE Monday, May 21 (Flight Day 3): Live coverage from NASA's Johnson Space Center mission control in Houston as the Dragon spacecraft performs its flyby of ISS to test its systems begins at 2:30 a.m. and will continue until the Dragon passes out of the vicinity of the station.
