[amsat-bb] NASA Announces Fourth Round of CubeSat Space Mission Candidates
RELEASE: 13-064 NASA ANNOUNCES FOURTH ROUND OF CUBESAT SPACE MISSION CANDIDATES WASHINGTON -- NASA has selected 24 small satellites to fly as auxiliary payloads aboard rockets planned to launch in 2014, 2015 and 2016. The proposed CubeSats come from universities across the country, a Florida high school, several non-profit organizations and NASA field centers. CubeSats belong to a class of research spacecraft called nanosatellites. The cube-shaped satellites measure about 4 inches on each side, have a volume of about 1 quart, and weigh less than 3 pounds. The selections are from the fourth round of the CubeSat Launch Initiative. After launch, the satellites will conduct technology demonstrations, educational research or science missions. The selected CubeSats will be eligible for flight after final negotiations and an opportunity for flight becomes available. The following organizations submitted winning satellite proposals: -- The Aerospace Corporation, El Segundo, Calif. -- The Discovery Museum and Planetarium, Bridgeport, Conn. -- Embry-Riddle Aeronautical University, Prescott, Ariz. -- Morehead State University, Morehead, Ky., in partnership with the University of California at Berkeley -- Montana State University, Bozeman (2 CubeSats) in partnership with The University of New Hampshire, Durham -- Merritt Island High School, Florida, in partnership with California Polytechnic State University, San Luis Obispo -- NASA's Ames Research Center, Moffett Field, Calif. -- NASA's Goddard Space Flight Center, Greenbelt, Md. (3 CubeSats) -- NASA's Jet Propulsion Laboratory, Pasadena, Calif., in partnership with the California Institute of Technology, Pasadena (3 CubeSats) -- NASA's Kennedy Space Center, Florida -- Pennsylvania State University, in partnership with the Naval Research Laboratory, Monterey, Calif., and the Aerospace Corporation, El Segundo, Calif. -- Saint Louis University, St. Louis -- Tyvak Nano-Satellites Systems, Irvine, Calif., in partnership with the California Polytechnic State University, San Luis Obispo -- University at Buffalo, The State University of New York -- University of Colorado, Boulder -- University of Florida, Gainesville, in partnership with Stanford University -- University of Maryland, Baltimore County -- University of Texas, Austin -- Vanderbilt University, Nashville, Tenn., in partnership with the Radio Amateur Satellite Corporation, Silver Spring, Md. In the three previous rounds of the CubeSat initiative, NASA has selected 63 missions for flight. The agency's Launch Services Program Educational Launch of Nanosatellite (ELaNa) Program has launched 12 CubeSat missions. This year, 22 CubeSat missions are scheduled for flight.

[amsat-bb] Re: Close encounters of the Asteroidal Kind
http://www.jpl.nasa.gov/news/news.php?release=2013-063 NASA Releases Radar Movie of Asteroid 2012 DA14 Jet Propulsion Laboratory February 19, 2013 [Image] This collage of 72 individual radar-generated images of asteroid 2012 DA14 was created using data from NASA's 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif. Image credit: NASA/JPL-Caltech An initial sequence of radar images of asteroid 2012 DA14 was obtained on the night of Feb. 15/16, 2013, by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif. Each of the 72 frames required 320 seconds of data collection by the Goldstone radar. The observations were made as the asteroid was moving away from Earth. The asteroid's distance from the radar dish increased from 74,000 miles (120,000 kilometers) to 195,000 miles (314,000 kilometers). The resolution is 13 feet (four meters) per pixel. The images span close to eight hours and clearly show an elongated object undergoing roughly one full rotation. The images suggest that the asteroid has a long axis of about 130 feet (40 meters). The radar observations were led by scientists Lance Benner and Marina Brozovic of NASA's Jet Propulsion Laboratory, Pasadena, Calif. Additional Goldstone radar observations are scheduled on February 18, 19 and 20. Radar is a powerful technique for studying an asteroid's size, shape, rotation state, surface features and surface roughness, and for improving calculations of its orbit. Radar measurements of asteroid distances and velocities often enable computation of asteroid orbits much further into the future than if radar observations weren't available. NASA detects, tracks and characterizes asteroids and comets passing close to Earth using both ground- and space-based telescopes. The Near-Earth Object Observations Program, commonly called Spaceguard, discovers these objects, characterizes a subset of them, and plots their orbits to determine if any could be potentially hazardous to our planet. JPL manages the Near-Earth Object Program Office for NASA's Science Mission Directorate in Washington. JPL is a division of the California Institute of Technology in Pasadena.

This object will make an extremely close approach to within 0.00023 AU of Earth at 19:25 UT (11:25 AM PST) on February 15, 2013. That is only 0.09 lunar distances or 5.4 Earth radii from the center of the Earth. The close approach will be about 28000 km above Earth's surface. That's inside the distance to geosynchronous satellites but thousands of kilometers above the elevation for low-Earth-orbit spacecraft such as the International Space Station. At the time of closest approach, the asteroid will move about 0.8 degrees per minute. There is considerable interest in the astronomy community over plans to do radar tracking of the asteroid.

Now the question, the other day I was looking at one of the information pages the unit can display and on it, it gives the time in UTC. Just for fun I thought I would see how close the time was to WWV. I was surprised to see the unit was between one to four seconds off over various tests compared to WWV.

I think some of the newer receivers can compensate for this, but I'm not sure. It's been about 14 years since I last worked in the GPS industry, and I'm a bit rusty on all the new stuff! 73, Jim KQ6EA On 02/02/2012 04:57 PM, George and Cheryl Abbott wrote: I'm not sure about GPS,but I have noticed that the clock on our cable box is off by up to 4 seconds at times.Customer service was not aware or concerned when I let them know.

[amsat-bb] Here's something we could try.
If Amsat won, we could use the winnings to launch a HEO. KB7ADL --- RELEASE: 11-370 NASA AND SPACE FLORIDA SMALL SATELLITE RESEARCH CENTER PARTNER IN SPACE LAUNCH CHALLENGE WASHINGTON -- NASA has signed an agreement with the Space Florida Small Satellite Research Center of Cape Canaveral, Florida, to manage the Nano-Satellite Launch Challenge, one of the agency's new Centennial Challenges prize competitions. The Nano-Satellite Launch Challenge is to launch satellites with a mass of at least 2.2 pounds (1 kg) into Earth orbit, twice within the span of one week. The new challenge has a NASA-provided prize purse of $2 million. The objective of the competition is to encourage innovations in propulsion and other technologies, as well as operations and management relevant to safe, low-cost, small payload delivery system for frequent access to Earth orbit. Innovations stemming from this challenge will be beneficial to broader applications in future launch systems. They may enhance commercial capability for dedicated launches of small satellites at a cost comparable to secondary payload launches -- a potential new market with government, commercial, and academic customers. Monday's agreement between NASA and Space Florida for use of facilities at the Kennedy Space Center even better positions the organization for managing this new Nano-Satellite Launch Challenge, said Michael Gazarik, director for NASA's Space Technology Program at NASA Headquarters in Washington. Space Florida has extensive experience working with NASA, the FAA, the Air Force, commercial spaceflight companies and universities to advance their plans for spaceflight operations. We look forward to having the Space Florida Small Satellite Research Center overseeing the competition and bringing together innovative teams with creative problem-solving ideas. Space Florida submitted a proposal last spring in response to a NASA solicitation for this partnership opportunity. They will now begin detailed preparations for the challenge, publishing rules and then registering competitors. The first competition launch attempt is expected to take place in the summer of 2012. The Centennial Challenges seek unconventional solutions to problems of interest to NASA and the nation. Competitors have included private companies, student groups and independent inventors working outside the traditional aerospace industry. Unlike contracts or grants, prizes are awarded only after solutions are successfully demonstrated. NASA's Centennial Challenges program provides the prize purse for the technology and innovation competitions. The competitions are managed by non-profit organizations that cover the cost of operations through commercial or private sponsorships. In October, NASA awarded the largest prize in aviation history following Pipistrel-USA's win of the agency's CAFE Green Flight Challenge, sponsored by Google. NASA's $1.35 million first prize and a $120,000 second prize recognized competitors using electric airplanes to break all previous fuel efficiency records. The technology and innovation used in electric aircraft may end up in general aviation aircraft, spawning new jobs and new industries for the 21st century. There have been 22 Centennial Challenges competition events since 2005. NASA has awarded nearly $6 million to 15 different challenge-winning teams. Centennial Challenges is one of the ten Space Technology programs, managed by NASA's Office of the Chief Technologist.

During the sarex pass for the first school, we were still communicating with the astronauts for about 25 seconds after LOS. I have the whole thing on video. It didn't happen again the second pass, the weather was more normal. Back in those days, when you were scheduled for a contact, NASA faxed the latest keps for the shuttle.

One will collect information useful in seismic forecasts and earthquake predictions, and the second will look at gamma splashes and optical radiation during terrestrial lightning and thunderstorms. The spacewalkers also will retrieve a pair of panels exposed to space as part of an experiment to identify the best materials for building long-duration spacecraft. The cosmonauts also will deploy an experiment called ARISSat-1, or Radioskaf-V, a boxy 57-pound nanosatellite that houses congratulatory messages commemorating the 50th anniversary of Yuri Gagarin's launch to become the first human in space. The ham radio transmitter will enable communications with amateur radio operators around the world for three to six months. It is the first of a series of educational satellites being developed in a partnership with the Radio Amateur Satellite Corp.; the NASA Office of Education International Space Station National Lab Project; the Amateur Radio on the International Space Station working group; and RSC-Energia.

[amsat-bb] Re: 'Zombie-sat' and the clever orbital dance
At 02:03 PM 5/25/2010 -0400, kg4...@gmail.com wrote: The dead-but-alive telecommunications satellite, Galaxy-15 http://www.orbital.com/SatellitesSpace/Communications/PanAmSat/, has begun to enter the space of neighbouring craft, and their operators are planning evasive action. Zombie-sat has captured the imagination of the internet space forums these past few weeks. It's probably the nickname that's done it. When we sit on the sofa skipping across the smorgasbord of channels with our remote-controls, we don't usually give much thought to the bent pipes that sit 36,000km above our heads, delivering the televisual feast. Intelsat's Galaxy-15 http://www.intelsat.com/resources/galaxy-15/operational-status.asp satellite was put in geostationary orbit five years ago to re-distribute TV services to cable companies across North America, and also to send navigation data to aeroplanes to improve the accuracy of their GPS receivers. But the bird experienced a major hiccup at the beginning of April. It's not known precisely what happened. One possibility is that it was damaged by high-speed particles billowing off the Sun in a solar storm - an ever-present danger for orbiting electronics. The satellite is still operational: it's still on, but Intelsat cannot control it. Any signal it receives, it re-transmits at high power. It's a very unusual situation. What doesn't help is the fact that Galaxy-15, which is supposed to sit at 133 degrees West (over the eastern Pacific), is drifting slowing eastwards by about 0.05 degrees a day. This will take it into the path of other satellites, and first to have an issue is AMC-11 http://www.ses-worldskies.com/worldskies/satellites/01_amc-fleet/amc-11/index.php, another TV services spacecraft operated by SES World Skies http://www.ses-worldskies.com/worldskies/index.php. If SES were to do nothing, Zombie-sat would soon start picking up and retransmitting signals sent to AMC 11. To users on the ground who depend on AMC 11 for their daily dose of MTV, this could lead to a horrendous mash-up. It would be like trying to listen to two people who are shouting the same conversation at you. So, SES World Skies will today begin a delicate orbital dance, in which they will allow AMC 11 to drift in tandem with Galaxy-15 while at the same time sneaking up another satellite behind the pair. The plan is for the SES controllers to then leapfrog many of the services on AMC-11 across to this other satellite, known as SES-1, thereby minimising the disruption to customers. The manoeuvres are unprecedented, says Alan Young, the chief technology officer with SES World Skies. The closest AMC-11 and Galaxy-15 will come is measured in kilometres, and in space terms that's quite close. But the risk here is not one of collision; we're not at all concerned about that. The problem is that they're so close when viewed from Earth that it's not easy to distinguish between the two satellites and seeing as they both operate in the same frequency band, there will be interference if we're not careful. We've gone to a number of measures, including moving customers on AMC-11 on to a very large uplink antenna. This means we can very finely discriminate between the two spacecraft so that we can direct all of the energy into AMC-11 and as little energy as possible into Galaxy-15. If you don't put anything into Galaxy-15, you won't get anything out. AMC-11 will eventually be moved back to its orbital slot to resume normal operations once the zombie has passed through, which should be 7 June. All satellite operators and comms companies will have to work out what Galaxy-15 means to them. Here at the BBC, we've had to consider how some of our international services like the BBC World News channel http://www.bbcworldnews.com might be affected. This channel is fed through Intelsat's Galaxy-13 platform. The most recent calculations suggest everything should be fine. Anyone sitting on their sofa in North America should be oblivious to the space waltz that is about to take place. There are some wider issues, however. For satellite manufacturers, there will be keen interest in understanding exactly what happened to Galaxy-15. Satellites have redundant, or back-up systems http://news.bbc.co.uk/1/hi/sci/tech/8458203.stm; and when they have major upsets, there are usually modes that will completely re-boot the spacecraft automatically after a period of time. Galaxy-15 was made by Orbital Sciences http://www.orbital.com/, but Patrick Wood, the chief technical officer for EADS Astrium satellites http://www.astrium.eads.net/, told me the entire industry had an interest in finding out what went wrong: Part of our design review process is to check through the architecture to ensure there isn't a single point that, were it to fail, we'd lose complete control of the spacecraft.

If you want that extra 15km of altitude you get with AO-7 at apogee, the next time AO-7 will be having apogees at the most northern latitudes it reaches will be on orbits around June 17th to the 18th. Apogee will occur around 78 degrees N Lat. KB7ADL ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

There are a small number of frequent users that have a disproportionate use of the satellites. How do you expect to grow the organization if new people cant even get into the satellites.

My solution is to stick to the linear birds where the QSO's are longer and the operators friendly. If you need Montana, I'm on all the linear birds almost every evening from about z to 0500z.

[amsat-bb] Spacewalks
I was thinking while watching last nights EVA on the ISS, has anyone here ever tried to intercept the space suit communications during EVA's? I'm not sure what the output of the transmitters are, but with a good system you still should be able to hear 100 - 200mw. Probably a weird digital transmission mode so you still wouldn't be able to tell was they were saying, but that's why there is NasaTV. ___ Sent via amsat...@amsat.org.

[amsat-bb] Landwehr 2m Pre-amp issue
I was suspecting my 2m Landwehr was having problems one day, don't know when it really started having problems, but last night I checked it out. Last night when I was listening to AO-7, when I turned the pre-amp on I got about S 7 of noise and the signals from the satellite were buried in the noise, and I couldn't tell that the signals were boosted much, but I could still hear them with difficulty through the noise. Turning the pre-amp off made hearing the signals easier, due to lack of noise. Obviously since I could still hear stations, RF is still going through the device. Checking it out on stronger fm signals, did seem to amplify them more, but I could tell there was still noise. I don't know much about gaAsFet's but what I guess I'm asking, is when they Fail, could they fail in the noisy position, or when then they fail do they die with no amplification? I guess it could be possible some other component around the gaasfet failed making the device run wild. Maybe dirty relay contacts? The RF sensor still works still works fine. I won't be able to get my hands on it for a while as there is too much snow on the roof yet, and I don't have weak signal noise generators to try to isolated the problems. Landwehr gives you a schematic but they didn't like to reveal too much. The pre-amp is about 16 years old. My 70cm Landwehr which is the same age and gets much more use is chugging away just fine. The 2m pre-amp is under an eggbeater. I don't need a 2m pre-amp on LEO's with the beam. Give me some things to check, Thanks, 73 KB7ADL ___ Sent via amsat...@amsat.org.

I'm only working with a quarter-wave ground plane at the moment, and it was only a 10 degree pass for me. I heard a couple of other stations, one of which was off-frequency on the uplink. We'll see what it's like later on a higher pass. George, KA3HSW I listened last night, and that was my thought too. The FM downlink from Echo was twenty over nine, with a lot of white noise in the background much like you hear when listening to a 9600 bps signal, but the audio level of the stations making contacts on it was low. Receiving Echo shouldn't be a problem if the output is lowered, at least for me anyway, but I wonder if it's possible to increase the receiver gain on Echo so SSB signals come out louder. To me it seemed the audio should have been louder as I was receiving the downlink almost full scale. ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

[amsat-bb] An interesting observation and thought on XW-1 and AO-7, VO-52.
I noted a number of times the past few days either AO-7 XW-1 or VO-52 XW-1 were visible to each other over NA. 5 KHz of VO-52s downlink and all of AO-7's 2m downlink fall into XW_1's uplink. With signals as strong as they are, it should be possible to make cross satellite contacts, ie. U/U. In on VO-52 or AO-7, out on XW-1. Just an observation but I don't recommend trying it as may interfere with other users. KB7ADL ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

I do more digital than voice, so my perspective is biased in that direction. Here are some of my thoughts: The CAT control of the TS-2000X is amazing. All menu options are available remotely via CAT. No so with the 910. The TS-2000X allows adjustments of modem/TNC levels in/out of the rig, 910 does not. The TS-2000X has built-in TXCO and DSP, 910 does not (yes, they are expen$ive options). The TS-2000X lets you work mode A, 910 does not. The TS-2000X gives me the full rated power output on both 2M and 70cm, the 910 does not (same antennas, feedlines, etc.)---does anybody have the solution to this? Even with flat SWR the 910 cuts back output to about 70-75W on 2M and 40-50W on 70cm!! Bummer The 910 receiver is much better on 2M than my TS-2000X, which is actually pretty deaf on 2M(even after doing the resistor mod to improve receive). The 910 does not have the AO-27/SO-50 birdy, while the TS-2000X does--this is my single biggest disappointment with this radio Tuning the TS-2000X off frequency by 5-7kHz above and below the real frequency helps a bit, but it's still a pain. In spite of the short comings of the TS-2000X, I don't think I'd trade it even up for an IC-910H with a the 1.2 gig module installed... 73, Mark N8MH Mark, Didn't you have a kenwood TS-790 too? I use the TS-790, and a TS-440s HF rig and wondered how the receivers in the TS-2000 compare to the receivers in the TS-790 on 2m and 70cm. I wonder if people like its HF performance, I would be using it on HF in place of my 22 year old TS-440. KB7ADL ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

Thanks in advance for everyone's help. Back what I used to call not so many years ago, maybe 1980-1985, I recall NASA mailing me 2-line elements for specific satellites I had selected. These would come in an official manilla envelope with an extremely official looking NASA label affixed to it. I recall these would arrive in my mailbox every week or so. Later they dwindled to perhaps one per month. At some point, they just stopped mailing them to me. Perhaps I had missed a reminder to update my subscription info. I'm assuming more than likely the free service just became redundant, as BBS systems, and later internet services began providing them online for free. Not to mention the Oscar data provided in the AMSAT Journal. An aside - you can skip this paragraph if you want me to cut to the quick - I was living in an apartment with my then new, now ex, wife. We were the only young couple in the complex. The ladies sitting in the breezeway thought we were gov'mt spies receiving coded instructions. They always kept one eye on us as we unlocked our mail slot, and pulled out one of these covert communiques. One accidentally was placed in another mail slot once. The nice elderly woman who lived below us returned it to me as I came home from work. She said, I think you'll be needing this. Handed it to me, and hurried back into her apartment. I tucked it under my coat, and went upstairs - I knew there were eyes peering out behind every door. I can't say that I tried to dispell the myth. My apologies, Ms. Maxine, in Apt 303... God rest her soul. Question(s): * Which NASA office did these originate from? * When did this service begin/end? * Could requests be made for any unclassified object in orbit, as long as the designator was known? For your eyes only, (ssshhh...) Rich, N8UX Hi Rich, I used to get the two line elements sets mailed to me too, and then I would type them into my tracking program manually.*ugly* They were mailed from GSFC. I don't know if they still do mail outs. When I was able to get them off the internet I had them stop sending me them by snail mail. Get on the AMSAT Keps list and you can get them by email.
