Astronaut Hams Complete ISS Crew Transition
The eleven orbital residents aboard the International Space Station (ISS) spent this week gearing up for a crew split as the four newest members continue to settle into their daily routines in weightlessness and four other Expedition 69 crew members prepare for their ride home to Earth.
Two crews are in the process of swapping places as NASA astronauts Woody Hoburg, KB3HTZ, and Stephen Bowen, KI5BKB, along with UAE (United Arab Emirates) Flight Engineer Sultan Alneyadi, KI5VTV, and Roscosmos Flight Engineer Andrey Fedyaev, spent most of their time handing over responsibilities, including training new crew members on station procedures and the use of station exercise equipment.
Sunday, August 27 saw the arrival of NASA astronaut Jasmin Moghbeli, KI5WSL, Danish ESA astronaut Andreas Mogensen, KG5GCZ, JAXA astronaut Satoshi Furukawa, KE5DAW, and Roscosmos cosmonaut Konstantin Borisov to the station as the SpaceX Dragon Endurance Spacecraft docked to the Harmony module. The international quartet is quickly adjusting to orbital tasks and spent some of Thursday on the firsts of many science and maintenance activities they’ll perform in microgravity during their six-month stay.
The four Crew-6 members -- Hoburg, Bowen, Alneyadi and Fedyaev -- are nearing the end of their six-month research mission and spent the afternoon prepping and packing SpaceX’s Dragon Endeavour spacecraft for departure no earlier than Sept. 2. This will bring the space station’s population down to seven before further crew swaps take place in September.
[As always, amateur radio operations on the ISS are suspended during docking and undocking maneuvers, as well as during spacewalks (EVAs). Amateurs on earth should expect interruptions of the ARISS FM repeater and ARISS digipeater this weekend.]
Astronaught Frank Rubio, and cosmonauts Sergey Prokopyev and Dimitri Petelin will soon reach a year in space after arriving to the station on Sept. 21, 2022, and are gearing up for their trek home in late September. The three long-time station residents continued to help with crew handover activities on Thursday and completed some station maintenance tasks of their own.

All South African Grids Roved on Satellite
Tom Ambrose, ZS1TA, has done one of those difficult roves that took several years to complete. He has worked All South African Grids which has never been done before on any band or mode let alone satellite.
Although there is no award, he has roved from 83 different ZS grids. Tom roved from the mountains to the sea and coast to coast. He used various antennas in including small Yagi's and dual band verticals. The satellites PRIMARILY used were AO-91 and AO-92, with occasional contacts on SO-50, using FM to encourage new satellite operators.
FO-29 and AO-07 also featured in the mix. There are not that many satellite operators in ZS however, when he started operating many old and new hams got on to make a contact and follow him on his trips.
Now comes the more difficult part. In order to receive VUCC/r, Tom has to go to another country to do some roves. Tom is looking at going through Namibia for that.
Congratulations to Tom for this feat and looking forward to processing his VUCC/r which will be a first for a ZS station.

Japan Scrubs Launch of X-Ray Telescope and Moon Lander
JAXA, the Japanese space agency, is attempting to launch two very different space missions from one rocket: a new X-ray telescope that will look at some of the hottest spots in our universe, and a small experimental robotic moon lander. But the missions have had difficulty getting off the ground.
The telescope is called X-ray Imaging and Spectroscopy Mission, or XRISM for short (pronounced like the word “chrism”). The lunar mission is called Smart Lander for Investigating Moon, or SLIM. XRISM and SLIM were expected to launch from an H-IIA rocket from Japan’s Tanegashima Space Center on Monday, August 28 at 00:26 UTC.
But less than 30 minutes before the scheduled launch, JAXA announced that the launch had been canceled for the day “due to inclement weather.” While JAXA had moments before said the weather appeared “calm,” winds at higher altitudes above the launch site were too severe for a safe launch according to a social media post by Mitsubishi Heavy Industries, which built and operates the rocket that is being used for the flight.
Poor weather had also led to an earlier postponement of the flight on Saturday. The Japanese space agency has not yet announced when the next launch attempt would occur. But it has a reserved launch period through Sept. 15.
XRISM is a telescope about the size of a bus. JAXA is collaborating with NASA on the mission, with additional participation from the European Space Agency. XRISM will study cosmic X-rays, which unlike other wavelengths of light can only be detected from above Earth’s atmosphere, which shields us from the harmful radiation.
SLIM is a compact robotic moon lander that weighs more than 1,500 pounds at launch. The lander’s mission is not primarily scientific. Rather, it is to demonstrate a pinpoint navigation system, aiming to set down within about the length of a football field of a targeted landing site. Developing better landing technology would enable future spacecraft to land closer to rugged terrain that is of scientific interest.
The space telescope will be placed in an orbit approximately 350 miles above Earth. Once there, researchers will spend the next few months turning the instruments on and running tests of their performance. Science operations will begin in January, and initial results from this data are expected in about a year.
SLIM is headed toward the Shioli crater on the moon’s near side. The spacecraft will be taking a long, roundabout journey of at least four months that requires less propellant. SLIM will take several months to reach lunar orbit, then spend a month circling the moon before attempting to set down on the surface.

Changes to AMSAT-NA TLE Distribution for Sept. 1
Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/
This week there are no additions or deletions to the AMSAT TLE distribution.

India's Lunar Lander Sparks Interest in the Moon
Chandrayaan-3’s lander and rover are safely on the Moon and their scientific work has begun. On August 23, the Vikram lander completed a successful autonomous descent and landing to touch down near the Moon’s south pole, only about 350 meters away from its target. On August 26, the Pragyan successfully rolled onto the lunar surface and navigated its first small crater.
With this success, India became the fourth nation (after the U.S., Soviet Russia, and China) to soft-land on the Moon. Not only is this mission a success for India, but is humanity’s closest landing to the lunar south pole -- an area of great interest to science, as there is speculation that water ice may be found in this area of the moon.
Landing a bit after sunrise on a lunar day, the Vikram lander with its four science payloads, and its onboard six-wheeled Pragyan rover with an additional two 2 payloads, have 14 Earth days to do some serious science together. All payloads have now been switched on, including ChaSTE onboard the lander, which measures the change in temperature with depth -- from ~50° C at the surface to -10° C over a depth of 8 cm in an initial test.
India's successful landing took place just days after Luna 25, Russia’s first post-Soviet lunar lander, suffered an anomaly during an orbit-lowering maneuver and crashed into the Moon. That leaves scientist eager for data from the Chandrayaan-3 mission.

+ Since satellite operators all have VHF and UHF equipment and antennas of some sort, you might try aiming at the horizon for a while on the weekend of September 9-11, and seeing what contacts can be made without a bird overhead. The ARRL Septmeber VHF Contest begins at 1800z on Saturday and ends at 0259z on Monday (actually, Sunday night in North America). There is even a category for FM only. For details, see https://www.arrl.org/september-vhf?_zs=s8mxl&_zl=lcFg2 (ANS thanks ARRL for the above information)
+ Curbing methane release is crucial to slowing climate change and requires detecting methane leaks via space and air-based sensors, and holding emitters accountable. This week, Orbital Sidekick utilized its hyperspectral satellite constellation GHOSt to detect methane plumes from oil well pads. And, data from JPL’s EMIT sensor on the ISS spotted 22 methane plumes released during an extreme heat wave in Texas. There are more methane sleuthing satellites on the horizon: GHGSat is adding 4 more satellites to their constellation that monitor facility leaks with ~25m spatial resolution today, and MethaneSat, set to launch in early 2024, is planning to observe state-sized areas to identify specific sources of methane from anywhere in the world, and will also freely release the data, where it can be post-processed by AI. (ANS thank The Orbital Index for the above information)
+ Virgin Galactic's announced on August 28 that it is targeting Friday, Sept. 8 for the launch of Galactic 03, its third commercial spaceflight and eighth space mission overall. Galactic 03 will take three paying customers to and from suborbital space from Spaceport America in New Mexico. Virgin Galactic hasn't identified those passengers yet, but we know they've been ticket-holders for a long time. They'll fly with Colin Bennett, one of Virgin Galactic's astronaut instructors. (ANS thanks Space.com for the above information)
+ NASA officials sounded an alarm Tuesday, August 29, about the agency's Deep Space Network, a collection of antennas in California, Spain, and Australia used to maintain contact with missions scattered across the Solar System. Everything from NASA's Artemis missions to the Moon to the Voyager probes in interstellar space rely on the Deep Space Network (DSN) to receive commands and transmit data back to Earth. There are currently around 40 missions that rely on the DSN's antennas to stay in communication with controllers and scientists back on Earth. Another 40-plus missions will join the roster over the next decade or so, and many of the 40 missions currently using time on the network will likely still be operating over that time. “We have reached a really critical point on the DSN’s aging infrastructure," said Sandra Cauffman, deputy director of NASA's astrophysics division.
