Defense News - Numerous organizations have recently lodged a fresh complaint regarding the environmental ramifications associated with SpaceX Starship launches. This comes amidst growing criticism directed at government agencies for both delaying these launches to conduct environmental reviews and allegedly neglecting comprehensive assessments.On December 15, a coalition of environmental groups declared that they had submitted an additional legal claim in federal court concerning the licensing of Starship launches from SpaceX Starbase facility near Brownsville, Texas. This move follows their initial lawsuit against the Federal Aviation Administration (FAA) in May, initiated shortly after the inaugural Starship launch on April 20.In the supplementary complaint, filed by entities including the Center for Biological Diversity, American Bird Conservancy, Carrizo/Comecrudo Nation of Texas, Inc., Save RGV, and Surfrider Foundation, it is asserted that the FAA failed to adequately evaluate the environmental impact of the first Starship launch. The complaint contends that the FAA issued a revised license for the second launch on November 18 without proper scrutiny.As part of the new licensing process, the U.S. Fish and Wildlife Service (FWS) conducted an environmental review concerning a pad deluge system installed by SpaceX to prevent damage similar to what occurred during the initial launch. The FWS concluded that this system would not cause significant environmental changes.The environmental groups argue that both the FAA and FWS fell short of their obligations under the National Environmental Policy Act (NEPA) in reviewing the environmental impacts of Starship launches. The complaint emphasizes that the FAA failed to take a comprehensive look at the impacts of the Starship/Superheavy launch program through a supplemental NEPA analysis.Jared Margolis, a senior attorney at the Center for Biological Diversity, expressed concern, stating, "Failing to do an in-depth environmental review and letting SpaceX keep launching the world largest rockets that repeatedly explode shows a shocking disregard for wildlife and communities. SpaceX should not be given free rein to use this amazing area as a sacrifice zone."While environmental groups criticize the government for what they perceive as insufficient measures to protect the environment from Starship launches, some argue that regulatory agencies are imposing undue delays. Senator Ted Cruz, at a December 13 hearing, claimed that the second Starship launch experienced months of delay due to bureaucratic red tape from various agencies.Kelvin Coleman, FAA associate administrator for commercial space transportation, defended the environmental review process, stating it was necessary to ensure compliance with NEPA and related environmental laws. However, Senator Cruz argued that these reviews resulted in unreasonable delays, hindering the United States competitiveness in spaceflight compared to other nations.NASA Deputy Administrator Pam Melroy, also present at the hearing, highlighted discussions with environmental regulatory agencies to emphasize the significance of activities like Starship. NASA has invested $4 billion in contracts with SpaceX for the development of a lunar lander version of Starship for the Artemis lunar exploration program.The FAA is currently overseeing a SpaceX-led investigation into the second Starship launch on November 18, where both the Super Heavy booster and Starship upper stage were destroyed. The investigation is progressing concurrently with the application for a license modification needed for the third Starship test flight. While no timeline has been set for completing the investigation, SpaceX CEO Elon Musk has expressed optimism about a potential launch by the end of the year, contingent upon the investigation conclusion and the issuance of a modified launch license.

Space News - On Friday, China successfully deployed the classified Yaogan-41 optical satellite into the geostationary belt, utilizing the nation largest launch vehicle, the sixth Long March 5 rocket. The launch took place at 8:41 a.m. Eastern (1341 UTC) from the Wenchang Satellite Launch Center along the coast, with the China Aerospace Science and Technology Corp. (CASC) confirming the mission success approximately an hour later.The Yaogan-41 satellite, developed by CASCs China Academy of Space Technology (CAST) subsidiary, featured an elongated 18.5-meter-long, 5.2-meter-diameter payload fairing, a departure from the previous 12.3-meter fairings. Despite limited visual information provided by CASC, state news agency Xinhua described the satellite as an optical remote sensing satellite, emphasizing its applications in land survey, crop yield estimation, environmental management, meteorological warning and forecasting, and comprehensive disaster prevention and reduction.However, external assessments suggest a potential military application for the Yaogan series, given the classified nature of the mission. The U.S. Space Force space domain awareness cataloged the spacecraft in a 195 by 35,815-kilometer orbit inclined by 19.51 degrees.This successful launch contributes to China expanding capabilities in on-orbit remote sensing. If Yaogan-41 assumes a position in geostationary orbit at around 35,786 kilometers above the equator, it would provide continuous observation of a fixed geographic area, covering about one-third of the Earth surface. Geostationary optical data holds significance for security, meteorology, climate studies, and environmental monitoring.This mission may be considered a potential military sequel to the civilian Gaofen-4 satellite launched in 2015. Unlike the Gaofen-4, the Yaogan-41 is transported by the larger Long March 5, capable of carrying payloads up to 14,000 kg to Geostationary Transfer Orbit (GTO).The Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) under the Chinese Academy of Sciences (CAS) played a role in producing critical components for space remote sensing. Additionally, CIOMP is involved in the development of Xuntian, a Hubble-class space telescope set to join the Tiangong space station in orbit in 2025.This launch follows China recent deployment of a geosynchronous orbit radar satellite in August, bolstering its GEO observation capabilities. The Long March 5, despite experiencing setbacks in its early flights, has become a reliable workhorse for China space missions, including the Tianwen-1 Mars mission and the Chang e-5 lunar sample return mission.Furthermore, China space exploration efforts continue, with the Long March 5 serving as the foundation for the upcoming Long March 10, featuring upgraded versions of the YF-100 kerosene-liquid engines and three five-meter-diameter cores.In a separate development, a day prior to the Yaogan-41 launch, China successfully placed its experimental reusable spacecraft into orbit for the third time. This spacecraft achieved an orbit ranging from 333 to 348 kilometers in altitude, inclined at 50 degrees.As of this launch, China has conducted 61 missions in 2023, contributing to the global total of nearly 200 orbital launches. Notable achievements include crew and cargo missions to Tiangong, satellite internet test satellites, and the initiation of commercial liquid propellant launches. While CASC aimed for over 60 launches this year, it appears to be falling slightly short of this target, although the organization has not experienced any launch failures since 2020.

Space News - Amazon has accomplished a successful trial of inter-satellite connectivity between its two Project Kuiper prototypes in low Earth orbit (LEO), marking a significant step as it gears up to establish a comprehensive mesh broadband network in space next year.The tests, conducted between KuiperSat-1 and KuiperSat-2, utilized onboard optical communication payloads, maintaining a robust two-way link of 100 gigabits per second (Gbps) for approximately an hour each time, according to Rajeev Badyal, the Vice President of Project Kuiper.Even though the satellites were nearly 1,000 kilometers apart during the experiments, the technology design allows for effective operation across distances of up to 2,600 kilometers. Amazon ambitious plans involve deploying over 3,200 satellites, and Badyal envisions them being positioned much closer than 1,000 kilometers as the constellation expands.The testing phase, initiated in early November shortly after the satellites orbital launch a month prior, has proven successful. This accomplishment now empowers Amazon to incorporate laser links into operational satellites that are set to enter production "any day now."Amazon in-house construction of each satellite includes multiple optical terminals, facilitating simultaneous communication with an unspecified number of satellites. Badyal highlighted the potential benefits of data transmission across Project Kuiper satellites, noting a 30% increase in speed compared to fiber optic cables on the ground, as light travels faster through space than through glass.The accelerated data transfer capabilities hold particular significance for industries like financial services, where split-second stock trades are commonplace. Furthermore, the ability for data to seamlessly traverse from one satellite to another on its route to a ground station is crucial for sectors such as maritime, aviation, and others situated beyond the reach of terrestrial gateways.Amazon move into optical inter-satellite links mirrors SpaceXs efforts with its Starlink LEO broadband constellation, which began integrating such links in early 2021 to avoid the need for ground stations over the poles to achieve global coverage.Beyond speed and efficiency, a mesh network in space significantly enhances network resilience. The capability to reroute data and bypass potential satellite failures is a critical aspect, aligning with the strategies of other proposed constellations like Telesat Lightspeed.Badyal expressed pride in the accomplishments of Project Kuiper, emphasizing that, despite Amazon relatively recent entry into the satellite design and building arena five years ago, they have achieved a milestone with inter-satellite link demonstrations, lasting an impressive 60 minutes and potentially longer.Amazon confirmation on November 16 of successful end-to-end tests for KuiperSat-1 and KuiperSat-2 paved the way for the commencement of production on commercial satellites employing the same architecture. The company aims to initiate launches for these commercial satellites in the first half of 2024, capitalizing on contracts secured with United Launch Alliance, Arianespace, Blue Origin, and a recent agreement with SpaceX.

Space News - On December 12, Air New Zealand revealed its intentions to conduct a trial of Starlink broadband on its domestic flights, entering the competitive arena of connecting aircraft through low Earth orbit (LEO) technology set to launch next year.The LEO service from SpaceX, known as Starlink, is scheduled to be implemented on two Air New Zealand planes by late 2024 for an initial trial period lasting four to six months. This initiative includes the installation on a turboprop-powered ATR aircraft, marking a significant milestone for the airline.Pending a successful trial run, Air New Zealand plans to expand the deployment of Starlink across other aircraft in its domestic fleet in 2025. As of October 31, the airline operated a total of 105 aircraft.Air New Zealand emphasizes that Starlink connectivity will provide passengers with internet access comparable to home, boasting low latency as low as 30 milliseconds.This partnership with Starlink positions the company as a key player in the aviation broadband sector, especially as rival LEO services from OneWeb, now under the ownership of geostationary satellite operator Eutelsat, are set to launch commercially for the aviation market in the coming year.While SpaceX directly sells Starlink to airlines, OneWeb satellite services are distributed through partnerships, such as the deal with Intelsat, which operates a fleet in geostationary orbit (GEO). Intelsat recently secured a deal to equip nearly 500 regional jets operated by American Airlines with an antenna that connects to both GEO and OneWeb satellites in LEO.Despite SpaceX early lead with Starlink, progress in the airline sector has been gradual, with technical and regulatory challenges requiring navigation. Some smaller U.S.-based regional jet service providers, like JSX, Flexjet, and Aero, have already launched Starlink services on their planes. However, major airlines like Hawaiian Airlines and airBaltic of Latvia have postponed plans to offer Starlink services until 2024.Details about the plans of Qatar Airways and Japan Zipair to deploy Starlink connectivity remain limited. The competition between OneWeb and Starlink is intensifying, especially with Alaska Airlines recent announcement on December 3 to acquire Hawaiian Airlines, suggesting a potential head-to-head clash between the two satellite broadband providers in the near future.

Space News - The Federal Communications Commission (FCC) has upheld its previous decision to deny Starlink nearly $900 million in rural broadband subsidies, reiterating that SpaceX satellite broadband service did not meet the requirements for participation in the Rural Digital Opportunity Fund (RDOF). The final denial, issued on December 12, affirms the FCC stance after a comprehensive legal, technical, and policy review.In December 2020, SpaceX had been provisionally awarded the subsidies following its participation in an auction during the first phase of the RDOF process. The company stood to receive $886 million over a decade to provide high-speed broadband to approximately 643,000 homes and businesses across 35 states, securing one of the largest shares of the multi-billion-dollar fund.However, the FCC emphasized that SpaceX, along with terrestrial telco LTD Broadband, failed to demonstrate how they would deploy services meeting RDOF conditions. The requirements include delivering download speeds of 100 megabits per second (Mbps) and upload speeds of 20 Mbps.Despite SpaceX provisionally awarded subsidies, the FCC highlighted that Starlink median download performance in the United States, according to Ookla speed tests, was 64.54 Mbps in the third quarter of 2023. While this represented a slight decline quarter-on-quarter, it marked a 22% increase from the 53 Mbps recorded during the same period in 2022. Median upload performance rose to 9.72 Mbps over the three months to the end of September.SpaceX expressed deep disappointment and perplexity regarding the FCC denial, arguing that the decision unfairly targeted them for not meeting RDOF speed requirements years ahead of any obligation to do so. In a letter to the FCC, SpaceX criticized the use of Ookla speed tests, claiming they were applied without warning and involved nationwide averages covering areas that would not be served with RDOF support.The company contended that the FCC decision directly undermines the RDOF purpose to connect unserved and underserved Americans. SpaceX vice president, Christopher Cardaci, asserted that Starlink is a viable and perhaps the best option to promptly connect individuals residing and working in rural and remote areas where reliable, affordable, or available high-speed, low-latency internet has been lacking.While SpaceX plans to enhance Starlink services with more powerful satellites, dissent has arisen within the FCC. Republican Commissioners Brendan Carr and Nathan Simington have opposed the regulator decision to deny subsidies to Starlink, expressing dissent from the majority decision.

Defense News - In the ancient epochs of Mars, when the Red Planet was not the arid expanse we know today, it boasted a lush environment with a thick atmosphere and liquid water gracing its surface. Delving into this intriguing past, researchers from the Indian Institute of Remote Sensing and the Indian Institute of Technology, Bombay, have undertaken a comprehensive exploration of ancient megafloods on Mars. Leveraging data obtained from the Mangalyaan mission, India maiden venture to the Red Planet, they have unraveled key details about the velocity and volume of these dramatic events.Signs of Mars" watery history manifest in various ways, from colossal piles of transported debris covering vast distances to the indelible imprints of turbulent waves etched onto the Martian ground. Eroded layers of sedimentary deposits bear witness to the planet bygone aqueous epochs. While the presence of water in Mars" ancient history is well-established, the specific timeline of its existence, and the enigmatic vanishing act of all that water, continue to baffle scientists. Thanks to ongoing advancements in Martian spacecraft, our understanding of these mysteries is evolving. The latest insights come from Indian researchers utilizing data from the Mars Orbiter Mission (MOM), also known as Mangalyaan, launched by the Indian Space Research Organisation (ISRO).The scientists meticulously traced the remnants of outflow channels, marking ancient flooding events that sculpted the Martian landscape. Their focus honed in on four regions—Mangala, Kasei, Ravi, and Maadim—all intricate networks of intersecting channels. Each of these areas experienced periodic flooding, potentially linked to intermittent volcanic activity. Spanning hundreds of kilometers across Mars, these outflow channel systems, known as "valles," showcase a rugged terrain shaped by the forceful flow of copious amounts of water. Employing advanced modeling techniques, researchers estimated the quantities and velocities of water coursing through these channels.For instance, the colossal Kasei Valles witnessed the movement of approximately 3.5 billion cubic meters of water at velocities exceeding 20 meters per second. Stretching over 2,000 kilometers with a maximum width of 260 meters, Kasei Valles stands out as the largest among the four discharge channels scrutinized in the study. These findings not only deepen our understanding of Mars" ancient hydrology but also serve as valuable guides for future missions to the Red Planet. Armed with insights into the specific regions where Mars once hosted water, scientists can direct their focus towards uncovering potential signs of ancient Martian life. The detailed findings of this research have been published in the journal Current Science.

Anticipated to reach Mach 5 speeds, this pivotal flight is slated to take place before the year concludes. Following this inaugural flight, a subsequent mission in early 2024 is planned, where the Talon-A system will achieve hypersonic speeds and execute a runway landing.The significance of the Talon-A test campaign extends to the Defense Department hypersonic endeavors, concentrating on the development and deployment of high-speed weapons. This initiative aims to counter similar systems being developed by China and Russia. The Talon-A system could provide the department with a reusable and cost-effective platform for testing and validating high-speed components, subsystems, and other crucial technologies, according to Zachary Krevor, CEO of Stratolaunch.While the exact cost of a single Talon-A flight remains undisclosed, Krevor emphasized that it is significantly less than the average cost of hypersonic flight tests conducted by the Department of Defense, which typically amounts to around $100 million. The prospect of achieving a monthly flight test cadence is expected to demonstrate a tangible return on investment for the Defense Department by the end of 2025.In the lead-up to the first hypersonic mission, Stratolaunch engineers and flight crews have meticulously prepared both the Roc and Talon-A through a series of ground and flight tests. These include a drop test, taxi test, and the recent completion of the first captive carry flight, providing valuable data on Talon-A propulsion system.As the company evaluates data from these tests, the Talon-A production line remains active, with three additional aircraft in various stages of assembly. The company ability to manufacture multiple systems simultaneously underscores its commitment to meeting the growing demand for reusable hypersonic flight testing services.Stratolaunch strategic acquisition of a second carrier aircraft, a Boeing 747 formerly owned by Virgin Orbit, further positions the company to accommodate the increasing demand for Talon-A flights. With a nearly full manifest for 2024 and existing contracts to support test flights, Stratolaunch innovative approach to hypersonic flight testing is poised to make a substantial impact on the Defense Department pursuit of advanced aerospace capabilities.

In a significant development, the Indian Space Research Organisation (ISRO) has selected its dependable workhorse rocket, the Polar Satellite Launch Vehicle (PSLV), to deploy the European Space Agency (ESA) experimental Project for On-Board Autonomy-3 (PROBA-3) mission in the middle of 2024. The PROBA-3 mission comprises two elements flying in tandem, dedicated to studying the Sun. Essentially, this mission creates a solar observatory measuring 144 meters in length, divided into two components flying in coordinated formation.ISRO has ambitious plans for 2024, aiming to conduct sixteen missions, marking its highest number of launches in a single year. Among these, the ESA has contracted one mission to ISRO, assigning the PSLV to transport an innovative technology demonstration mission to Earth orbit. The PROBA-3 mission includes a Coronagraph spacecraft and an Occulter spacecraft. The precise positioning of these two spacecraft in relation to each other is crucial, forming a unified instrument enabling scientists to explore the outer atmosphere of the Sun, known as the solar corona.Helio-Physics observatories, dedicated to studying the Sun, employ various scientific instruments to investigate different layers of the solar atmosphere. ISROs Aditya L1 mission, equipped with a sophisticated set of seven instruments, is designed for this purpose. To study the corona, it is necessary to block out the Sun face or disc, as it would oversaturate images. Traditionally, coronagraphs integrated within the spacecraft serve this purpose. However, the PROBA-3 mission adopts an innovative approach, utilizing two spacecraft flying in tandem, with the Occulter spacecraft observing the corona while the Coronagraph spacecraft blocks out the Sun face.The Indian Institute of Astrophysics (IIA) in Bangalore has played a crucial role in developing the Visible Line Emission Coronagraph (VELC) for the Aditya-L1 mission. Notable solar observatories like NASAs Solar Dynamics Observatory (SDO) and ESAs Solar Orbiter also incorporate coronagraphs. The PROBA-3 mission primary objective is to demonstrate the feasibility of formation flying, where the two spacecraft, separated by over 144 meters, will fly in coordinated formation for six hours. Together, these elements will act as a virtual giant satellite. The mission is anticipated to last approximately two years, with the PROBA-3 launch scheduled between July and September 2024.
