________________________________ SpaceX Transporter-11 Launches 116 Satellites, Including OreSat0.5

SpaceX successfully launched 116 payloads aboard its Falcon 9 rocket as part of the Transporter-11 rideshare mission on August 16, 2024. The launch occurred at 11:56 a.m. PDT from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. This mission is the latest in SpaceX's series of rideshare launches, which provide small satellites from various countries an opportunity to reach orbit without needing dedicated launch vehicles. Following stage separation, the Falcon 9's first-stage booster successfully returned to Landing Zone 4, marking its 12th flight and 20th landing at LZ-4.

Transporter-11 carried a diverse range of payloads, including satellites from Japan, Chile, the United Kingdom, and Australia. Among the Australian payloads were three satellites launched by the Australian Space Agency: Kanyini, Waratah Seed-1, and Cuava-2. Waratah Seed-1, a 6U CubeSat, hosted multiple payloads, such as the Perovskites in Orbit Readiness Test (PORT-2), the Submillimeter Particle Detection System (SPaDeS), and Spiral Blue Space Edge-1 (SE-1), showcasing the collaborative nature of this mission. [https://www.amsat.org/wordpress/wp-content/uploads/2024/08/SpaceX-Transporte...]https://www.amsat.org/wordpress/wp-content/uploads/2024/08/SpaceX-Transporter-11-Satellite-Payload.jpg SpaceX Transporter-11 launched 116 satellite payloads on August 16th. [Credit: @GewoonLukas_https://x.com/GewoonLukas_]

Oregon also had a key payload on Transporter-11 with the launch of OreSat0.5, the state's second satellite. Developed by the Portland State Aerospace Society (PSAS) at Portland State University, OreSat0.5 is a 2U CubeSat designed to demonstrate two critical systems: the attitude determination and control system (ADCS) of the modular OreSat bus and the Cirrus Flux Camera (CFC), which uses short-wave infrared (SWIR) technology. Deployed into a 510 km sun-synchronous low Earth orbit, the satellite began transmitting its first data beacons just 16 minutes after deployment, marking a significant milestone for the Portland State Aerospace Society team.

OreSat0.5's mission includes testing an open-source ADCS designed for precise antenna and camera pointing on amateur radio satellites, and demonstrating the "DxWiFi" S-band 802.11b bidirectional radio system for high-speed (1 Mbps) communication. Additionally, it aims to provide openly published flight performance data, including power and thermal characteristics, to support the development of cost-effective, scalable satellite systems. Telemetry data from OreSat0.5 can be received on 436.500 MHz and decoded using 9600 baud GMSK with DK3WN's GetKISS+https://www.dk3wn.info/files/getkissplus.zip v.1.4.2 software. The telemetry dashboard is viewable on the SatNOGS website: https://db.satnogs.org/satellite/DKCD-1609-0567-7056-3922.

The private astronaut mission Polaris Dawn is poised for launch on August 27, 2024, with a groundbreaking objective: the first commercial spacewalk. The four-member crew, consisting of Anna Menon, Scott Poteet, Jared Isaacman, and Sarah Gillis, arrived at the Kennedy Space Center on August 19 to finalize preparations. This mission, the first of the Polaris program, marks a significant step in commercial space exploration and is set to launch aboard a SpaceX Crew Dragon atop a Falcon 9 rocket from Launch Complex 39A.

Scheduled to last five days, the Polaris Dawn mission will propel the Crew Dragon spacecraft to altitudes reaching 1,400 kilometers, the highest for a crewed mission since Apollo 17 in 1972. The mission's objectives are multifaceted, including testing laser intersatellite links with SpaceX's Starlink satellites and conducting 40 experiments. However, the highlight will be the spacewalk, a historic first for a private mission, and the first from a Crew Dragon spacecraft. The spacewalk will involve all four astronauts, with two emerging from the hatch in new SpaceX-developed extravehicular activity (EVA) suits for a brief yet pivotal two-hour spacewalk. [https://www.amsat.org/wordpress/wp-content/uploads/2024/08/Polaris-Dawn-Comm...]https://www.amsat.org/wordpress/wp-content/uploads/2024/08/Polaris-Dawn-Commercial-Spacewalk-Illustration.jpg Polaris Dawn mission will propel the Crew Dragon spacecraft to altitudes reaching 1,400 kilometers. [Credit: @PolarisProgramhttps://x.com/PolarisProgram]

Jared Isaacman, the billionaire backing the Polaris program and commander of Polaris Dawn, emphasized the importance of the spacewalk during a press conference after arriving at KSC. "The idea is to learn as much as we possibly can about this suit and get it back to the engineers to inform future suit design evolutions," Isaacman stated. The spacewalk is scheduled for flight day three, with preparations beginning shortly after launch. The crew will undergo a prebreathing protocol to adjust the cabin's atmospheric pressure and increase oxygen levels, a process essential for the EVA.

SpaceX engineer Sarah Gillis, serving as a mission specialist, detailed the crew's rigorous preparations. On flight day two, the astronauts will don the EVA suits for mobility tests inside the spacecraft. During the spacewalk, two astronauts, referred to as EV1 and EV2, will take turns exiting the spacecraft for approximately 15 to 20 minutes each. Isaacman noted that while the idea of a free-floating spacewalk was considered, the crew will instead perform a "hands-free" demonstration with their feet securely attached to the spacecraft's mobility aids, underscoring the mission's cautious approach. [https://www.amsat.org/wordpress/wp-content/uploads/2024/08/Polaris-Dawn-Crew...]https://www.amsat.org/wordpress/wp-content/uploads/2024/08/Polaris-Dawn-Crew-Members-Inside-SpaceX-Crew-Dragon.jpg Polaris Dawn private astronaut mission crew members are shown inside a SpaceX Crew Dragon capsule. [Credit: @SpaceXhttps://x.com/SpaceX]

The mission's development has been intensely focused on the spacewalk and the associated EVA suits. "The EVA probably makes up the majority of the development for Polaris Dawn," Isaacman said, acknowledging the inherent risks. SpaceX vice president Bill Gerstenmaier, formerly of NASA, confirmed that extensive safety protocols have been implemented. He mentioned a recent issue where engineers identified and resolved a static electric discharge risk, ensuring the crew's safety during the spacewalk.

Polaris Dawn's mission profile includes a launch window between 3:38 and 7:38 a.m. Eastern on August 27, carefully chosen to minimize risks from micrometeoroids and orbital debris. After reaching an initial orbit, the spacecraft will ascend to 1,400 kilometers before lowering to 700 kilometers for the spacewalk. The mission will conclude with a demonstration of Starlink capabilities on flight day four, followed by reentry on day six. As the first of three planned missions under the Polaris program, Polaris Dawn represents a significant leap forward in commercial spaceflight, setting the stage for future endeavors, including a potential crewed Starship launch.

+ Russia successfully launched its 89th Progress cargo spacecraft, Progress MS-28, to the International Space Station (ISS) on August 15, 2024. The uncrewed spacecraft lifted off from the Baikonur Cosmodrome in Kazakhstan aboard a Soyuz rocket at 0320 UTC. Carrying nearly three tons of food, scientific equipment, and other supplies, the spacecraft autonomously docked with the ISS on August 17 at 0553 UTC, connecting to the rear port of the Zvezda service module. This docking occurred just days after the previous cargo spacecraft, Progress MS-26, was deorbited on August 12 following its six-month mission. With its arrival, Progress MS-28 joined two other freighters, including Cygnus NG-21, and three crewed spacecraft already at the ISS. The successful mission continues Russia's long-standing contribution to ISS resupply operations. (ANS thanks Mike Wall, Space.comhttps://www.space.com/, for the above information)

+ The European Space Agency's Jupiter Icy Moons Explorer (Juice) mission is making headlines with its dual gravity assist maneuver this week. After a successful flyby of the moon on August 19, 2024, Juice passed Earth on August 20, 2024, marking the first-ever lunar-Earth double flyby. This maneuver uses Earth's gravity to adjust Juice's trajectory, setting it up for a flyby of Venus in August 2025 and ultimately aiming for Jupiter's orbit by July 2031. The spacecraft's two cameras are capturing and sending images back to Earth, while mission operators are closely monitoring the high-risk maneuver to ensure precision. With Jupiter being nearly 500 million miles away, this gravity assist strategy allows Juice to conserve fuel and carry a variety of scientific instruments. The mission's success relies on careful navigation and timing, as any deviation could jeopardize its ambitious goals. (ANS thanks Ashley Strickland, CNNhttps://www.cnn.com/, for the above information).

+ Space is hard: NASA's BurstCube, which deployed from the ISS in April, is a 6U CubeSat that detects gamma rays from short gamma-ray bursts, likely caused by neutron star collisions. BurstSat, unfortunately, lost one of its magnetorquers during commissioning, along with one solar panel that did not fully deploy. The team has been able to continue the satellite's mission by compensating for the malfunctioning equipment through the use of a Sun-pointing configuration. But due to these failures, the mission will likely reenter sooner than expected, around the end of 2024. [Before complaining about the failure of your favorite HamSat, consider that even NASA has issues!] (ANS thanks The Orbital Indexhttps://orbitalindex.com/ for the above information.)

+ The FCC has granted SpaceX permission to upgrade its first-generation Starlink satellites with second-generation technology, aiming to enhance broadband quality for its users. This upgrade is expected to improve service, especially in polar regions, by using advanced beam-forming and digital processing technologies. SpaceX initially launched first-generation satellites in 2019 and applied in 2023 to integrate the new technology. Despite pushback from Dish Network over potential interference issues, the FCC dismissed these concerns, supporting SpaceX's plans to optimize spectrum use and increase network capacity. SpaceX will replace the older satellites with upgraded ones as they reach the end of their operational period, rather than de-orbiting them rapidly. The overall goal is to provide more robust service to underserved areas across the country. (ANS thanks Michael Kan, PCMaghttps://www.pcmag.com/, for the above information).
