FCC Considers UHF/Microwave Ham Bands for Commercial Space Launch Frequencies
The FCC in April issued a Report and Order allocating spectrum in the 2200-2290 MHz range for private space travel and satellite launch companies to use for pre-launch testing and space launch operations. The order creates a non-federal secondary allocation for these uses in spectrum that is currently reserved exclusively for federal government use. The action also includes a Further Notice of Proposed Rulemaking which seeks comment on possible additional spectrum for private space launch purposes. Among the frequencies specifically mentioned are 420-430 MHz in the 70-centimeter amateur band and 5650-5925 MHz, which is the 5-centimeter ham band. Amateur radio has a secondary allocation in each of these bands, and the NPRM made no mention of the bands' current occupants and/or whether they would be displaced. The 5.6-GHz band is already shared widely with home WiFi networks.

ASU student-built spacecraft to interact with the public
NASA has selected an Arizona State University-designed spacecraft to fly as an auxiliary payload aboard a rocket launching between 2022 and 2025. It is among 14 small research satellites, called CubeSats, that were chosen for this opportunity through NASAs CubeSat Launch Initiative. The ASU CubeSat, named LightCube, is about the size of a toaster and will be deployed to low-Earth orbit (LEO). Its unique feature is that it can be commanded by anyone with an amateur radio license and a ham radio to set off a xenon flash from the spacecraft that will be visible from the ground. Additional Details are available at https://bit.ly/3fF9v4B

Canadian Researchers Highlight Concerns About Overcrowded Orbits
A new report by two Canadian researchers is highlighting the growing hazard of space debris. It warns that the new mega-constellations of tens of thousands of communication satellites could pose a new kind of danger that could ultimately threaten other satellites, astronauts, our ability to use space and could even have an impact on the climate. Recently, the uncontrolled fall from space of a large Chinese rocket booster gained worldwide attention as no one could predict where it would come crashing to Earth. Fortunately, it came down in the Indian Ocean and no one was injured. That was just one booster. But the amount of stuff satellites, discarded boosters and other debris in Earth orbit is huge. And this new report warns that with projects like the SpaceX Starlink satellite constellation, the issue of space debris could approach a critical turning point. Right now, Starlink has full approval within the current legal system to go ahead and launch 12,000 satellites, and they want to put up 30,000 more, so there will be 42,000 satellites. With Starlink alone, there will be more satellites in the sky than there are naked eye visible stars. And that's not all. Others have similar plans, including OneWeb, Amazon, Telesat, and GW, which is a Chinese state-owned company. This astounding number of satellites will outnumber the total number of objects orbiting the Earth today and form shells around the planet in low Earth orbit up to about 750 km altitude. The more objects placed in orbit, the greater the chance of collision between them, other working satellites, astronauts working in space, and people on the ground when the objects fall out of orbit. The new satellites launched by SpaceX and other companies are not just thrown up willy-nilly. They're placed in careful orbits meant to minimize risks of collision, and modern satellites are designed to be de-orbited when they die, not just abandoned as space junk. The commercial space companies must have plans to do this in an organized and safe way. This is all good and responsible. The report highlights the possibility and implications of accidents. Random pieces of untracked space debris, or even meteors, could disable these satellites, disrupting their careful orbits and the deorbiting plans. The sheer number of these new satellites increases the risk.

Andy MacAllister, W5ACM, SK
From Marty Smith, WV5Y: "It's with much sadness and deep regret I announce our buddy, Andy, W5ACM - Past AMSAT Board of Directors, King of the South Texas Balloon Launch Team, The Voice of The Houston AMSAT Net and KTRU Rice Radio Engineer and DJ, AndyMac - Passed away on the evening of Wednesday, 5/19/2021. Andy's wife Heather said he was on his computer until a few minutes before... His funeral service was held on Thursday, May 27th 2021 at 12:30 PM at the Pines Presbyterian Church (12751 Kimberley Ln, Houston, TX 77024-4097). Andy will be missed very much by all of his family, friends and coworkers. He lived life to the fullest, and his lust for life was contagious. Our common interests in everything high tech, scientific & electronic, was shared by many, and he had great taste in food, drink, and music, especially loving classic rock & roll! He will forever be in our minds and hearts. 73, Marty Smith, WV5Y"
From AMSAT Director Bruce Paige, KK5DO: "Andy, W5ACM (ex WA5ZIB), became a Silent Key on May 19, 2021. He has been a close friend of mine since I became a ham in 1993. That was when I found satellites and AMSAT. Andy had been doing the Houston AMSAT Net and I became involved in the net. We have done over 1400 episodes of the net since then. Andy and I had a great time at many AMSAT Symposiums where we would work satellites from parking lots of restaurants or outside a hotel. During the AMSAT Symposium in 2016, we worked each other from the deck of the cruise ship when we were standing about 3 feet from each other. Andy spent some time in the early 90's on the AMSAT Board of Directors. Many of today's hams would not remember the K2ZRO tests on AO-13. When the satellite was at apogee, Andy would transmit a string of CW characters. He would then reduce his power by 50% and transmit another string of characters. This would be done 8 times to a point where the signals were very weak. Hams around the world would participate and receive a certificate with an endorsement for the level you achieved. Andy got into balloon launches. I do not remember when BLT-1 was launched but BLT-12 was launched in 1993 and they are into the 60's now. The balloons have gone up with all types of experiments on them and have come down in many a strange place. One came down in the Gulf of Mexico, picked up by a fishing boat and they called the number on the package. Of course that one was not reusable as everything was a tad bit wet. The balloon came down in someone's front yard once and they picked it up and took it inside. GPS told the tale and knocking on the door, the homeowner returned the package. A few recent balloon launches have traversed the globe one or two times. Andy had worked at NASA and was a member of the Johnson Space Center ARC as well as the Brazos Valley ARC in Houston, the ARRL and AMSAT. More recently he was the Chief Engineer for the radio station, KTRU, at Rice University in Houston. Andy gave talks and demos at many Houston area hamfests. It was only a few months ago in February that Andy went in for a quick procedure and they found something that should not be. He was sent home for hospice care. You will be missed my friend. ... _._ 73...Bruce"
Andy's wife, Heather, has requested that donations in his name be made to AMSAT or the Brazos Valley Amateur Radio Club, P.O. Box 2997, Sugar Land, TX 77487-2997 (reference the Andy MacAllister BLT Memorial Fund). Donations to AMSAT in his name may be made at https://www.amsat.org/donations/w5acm-memorial/

PSAT2: DTMF *and* APRS-to-Voice enabled
A new feature has been enabled for the Voice Synthesizer on PSAT2 in addition to DTMF grid and DTMF messaging to voice. Now the voice synthesizer is also listening for APRS-to-Voice messages as well. Here is how to use it 1) Remain on the 145.980 uplink and 145.825 downlink for DTMF 2) Using an APRS radio, send an APRS message to PSAT-SAY 3) Begin the first 10 chars of the message with CCCCCC sez 4) Followed by the text to be spoken. 5) CCCCCC is your callsign right-padded with spaces.
The satellite should ACK the packet uplink and then speak the text. You can tell if APRS-to-Voice is enabled if this 1 bit is on: XXXX0010. Usually the DTMF bits are also enabled so the telemetry will usually show as 11010010. To do both DTMF and APRS-to-Voice at the same time, the Basic Stamp processor has to check both the DTMF decoder and the packet decoder and so there is a finite chance that a perfectly good uplink might be missed. So, just try again. See http://aprs.org/psat2.html Tomorrow I will add this feature to the users manual and post it. Enjoy, Bob, WB4APR

NASA Schedules Live Coverage of Russian Spacewalk
Two Russian cosmonauts are scheduled to conduct a spacewalk outside the International Space Station on Wednesday, June 2, to continue preparing the Pirs docking compartment airlock for undocking and disposal later this year. Live coverage will begin at 1 a.m. EDT (0500z), with the spacewalk beginning about 1:20 a.m. (0520z) on NASA Television, the agencys website, and the NASA app. Expedition 65 Flight Engineers Oleg Novitskiy and Pyotr Dubrov of Roscosmos will emerge from the Poisk module on the space-facing side of the Zvezda service module for a spacewalk expected to last about six and a half hours. The two cosmonauts will disconnect all external mechanical links between Pirs and the station, reposition spacewalk hardware and antennas, and relocate other gear previously used for spacecraft dockings to Pirs. During the spacewalk, the cosmonauts will prepare Pirs for removal from its port by the uncrewed Progress 77 cargo ship on the Earth-facing side of Zvezda, clearing the way for the arrival of the new Russian Multi-Purpose Laboratory Module named Nauka, which is Russian for science. The undocking of Pirs is scheduled for this summer, about two days after Nauka launches from the Baikonur Cosmodrome in Kazakhstan. The cosmonauts also will replace a fluid flow regulator on the nearby Zarya module and replace biological and material science samples on the exterior of the Russian modules. Novitskiy, who is designated as extravehicular crew member 1 (EV1), will wear a Russian Orlan spacesuit with red stripes. Dubrov will wear a spacesuit with blue stripes as extravehicular crew member 2 (EV2). This will be the first spacewalk for both cosmonauts and the 238th spacewalk overall in support of space station assembly, maintenance, and upgrades. It also marks the sixth spacewalk of 2021.

The number of satellites whizzing along above our heads is truly mindboggling, with the number growing daily. Each of these spacecraft is up there for a specific reason, and a lot of them are doing interesting things. Listening in on what they have to say can be a lot of fun, but learning the ropes and getting that first capture can be tricky. Paul Marsh will stop by the Hack Chat to share the ins and outs of monitoring satellite communications and give us some insight into what the satcom hobby is all about.

+ The possibility of a Europa Lander is under study. Intense radiation from Jupiter converts ice and dust on the surface of its icy moon Europa into energetic compounds, which may cycle through the ice and ultimately be food for microbes in the ocean below. NASA has been developing a potential Europa Lander mission to look for such chemistry since 2016 (and also previously in 2005 and 2012). This mission concept proposes a 575 kg battery-powered lander with a limited (but still impressive) lifespan of 1-3 months.
