NASA is expanding options for companies involved in the development and production of the U.S. Deorbit Vehicle (USDV) for the International Space Station (ISS). In a recent procurement notice, NASA revealed that companies can now choose between firm fixed price or cost-plus incentive fee contract structures for both the design and production phases of the USDV.Originally, when NASA issued the request for proposals (RFP) in September, bidders were given the flexibility to propose a "hybrid" approach, opting for a cost-plus contract for development and a fixed-price contract for production. Alternatively, they could propose an entirely fixed-price contract for both development and production. The recent update introduces a new option, allowing companies to perform both the development and production phases under cost-plus contracts. The rationale behind this change was not disclosed in NASA procurement notice or accompanying blog post.In addition to the contract structure modifications, NASA has extended the deadline for proposal submissions. Initially set for November 17, the deadline was extended to December 14 and has now been further postponed to February 12. The agency anticipates making the award announcement in late May or early June, shifting from the originally expected award date in April 2024.The USDV serves a critical role in the controlled reentry of the ISS at the end of its operational life. NASA fiscal year 2024 budget proposal included a request for $180 million for the vehicle, estimating its total cost to be around $1 billion. The revised RFP outlines both "desired" and "required" delivery dates for the USDV. The desired delivery date is set for August 1, 2028, with a launch planned four months later. The required delivery date is May 1, 2029, also with a launch four months later. Proposals failing to meet the required delivery date will be deemed nonresponsive and rejected.The proposed delivery schedule aligns with NASA and its Western partners plan to retire the ISS in 2030. While Russia has committed to ISS operations only until 2028, the RFP accommodates pricing options for storing the USDV on the ground in a "Dwell facility" through 2035.

The spacecraft responsible for delivering the Chandrayaan-3 lander to the moon has successfully returned to Earth orbit, showcasing essential technologies for a prospective Indian lunar sample return mission. The Indian Space Research Organisation (ISRO) made the announcement on December 4, revealing that the propulsion module for the Chandrayaan-3 mission is now positioned in a high Earth orbit. Notably, ISRO had not previously disclosed plans to bring the propulsion module back to Earth orbit.Initially weighing 2,145 kilograms, the propulsion module, a modified version of ISROs I-3K satellite bus, played a crucial role in transporting the Chandrayaan-3 lander from an initial elliptical Earth orbit to a low lunar orbit. Following its launch on July 14, the module underwent a series of maneuvers, including raising the apogee of the orbit, translunar injection burn, and lunar orbit insertion burn. The module then achieved a nearly circular orbit around 150 kilometers above the moon before the lander separated on August 17.While the lander successfully touched down on the moon on August 23, the propulsion module continued to operate in orbit, employing an instrument named Spectro-polarimetry of Habitable Planet Earth (SHAPE) to observe the Earth. After the lander separation, ISRO provided limited information about the propulsion module activities.According to ISROs statement, the decision to bring the propulsion module back to Earth orbit was based on the realization that there was an excess of more than 100 kilograms of propellant remaining on the spacecraft. The maneuvers to return the module to Earth orbit commenced on October 9, raising the high point of its orbit around the moon from 150 to 5,112 kilometers.Subsequent maneuvers included a transearth injection on October 13, involving four close approaches to the moon before leaving its sphere of influence on November 10. The spacecraft then entered a high orbit around Earth, reaching its first perigee on November 22 at an altitude of 154,000 kilometers.ISRO explained that these maneuvers allowed SHAPE to continue observations closer to Earth, emphasizing their role in gathering additional information for future lunar missions and demonstrating mission operation strategies for a sample return mission.Although ISRO has not formally announced plans for a lunar sample return mission, discussions about the potential of such a mission have taken place. The next lunar mission on ISROs agenda is the Lunar Polar Exploration Mission (LUPEX), a joint effort with the Japanese space agency JAXA, expected to launch no earlier than 2026. The return of the propulsion module to Earth orbit marks a significant step in advancing technologies for lunar exploration and potential sample return missions.

Security researchers recently uncovered a sophisticated Android malware named FjordPhantom, which has been actively targeting users in Southeast Asian countries, including Indonesia, Thailand, and Vietnam, since early September 2023.According to an analysis by Oslo-based mobile app security firm Promon, FjordPhantom employs a combination of app-based malware and social engineering techniques to defraud banking customers. The malware predominantly spreads through messaging services, utilizing email, SMS, and messaging apps to trick recipients into downloading a fake banking app. This deceptive app includes seemingly legitimate features but also incorporates malicious components.One distinctive feature of FjordPhantom is its use of virtualization to run malicious code within a container, allowing it to operate discreetly. This technique breaks Android sandbox protections by enabling different apps to run on the same sandbox, granting the malware access to sensitive data without requiring root access.Security researcher Benjamin Adolphi explained that virtualization solutions used by the malware can inject code into an application by loading its own code into a new process and then introducing the code of the hosted application. In the case of FjordPhantom, the malicious module is included in the host app, along with the virtualization element. This combination is utilized to install and launch the embedded app of the targeted bank within a virtual container.Essentially, the deceptive app loads the legitimate banking app in a virtual container while employing a hooking framework to alter the behavior of key APIs. This manipulation allows FjordPhantom to programmatically capture sensitive information from the legitimate app screen and close dialog boxes intended to warn users about malicious activity.When asked for a response, a Google spokesperson assured users that Google Play Protect provides protection by warning or blocking apps exhibiting malicious behavior on Android devices with Google Play Services, even if sourced from outside Google Play.FjordPhantom is designed in a modular way, allowing it to adapt its attacks based on the specific banking app it targets. Depending on the embedded banking app, the malware tailors its attacks to exploit vulnerabilities in various banking applications.

Australian startup Infinity Avionics is currently in the development phase of a cutting-edge dual-headed camera system designed for space-based surveillance. Securing funding totaling approximately 1 million Australian dollars ($660,000) from the Australian research consortium SmartSat CRC, the Australian Capital Territory government, and internal research funding, Infinity Avionics, headquartered in Canberra, has partnered with the University of New South Wales Canberra Space and fellow Australian startup Nominal Systems. The primary goal is to create technology capable of autonomously identifying space objects, particularly those too small for radar detection.Igor Dimitrijevic, the founder and CEO of Infinity Avionics, explained that the focus is on detecting debris fragments that elude radar detection capabilities. The innovative camera system comprises a wide field of view event sensor designed to respond to changes in light without generating images. According to Dimitrijevic, this sensor boasts a remarkably high dynamic range compared to conventional image sensors, enabling the detection of subtle changes or events.The system operates on a "Tip and Cue" mechanism: when the event sensor detects changes or movement, it instructs the co-aligned narrow field of view camera to capture imagery. This approach allows for the identification of events or movements that might be overlooked by a standard camera. Additionally, it mitigates the challenge posed by massive data generation, which occurs when using a regular camera that constantly captures frames. With the dual-head camera system, Infinity Avionics can identify and capture events while producing a manageable amount of data for downstream processing and transmission.Nominal Systems, a technology company based in Canberra, contributes to the project with its digital twinning technology, aiding Infinity Avionics in simulating the concept of operations for the dual-headed camera system and validating requirements.Damith Abeywardana, founder and managing director of Infinity Avionics, highlighted that their system is an enhanced version designed to automate and introduce intelligence to surveillance cameras, building on the company existing expertise in providing cameras and sensors for similar space-based applications.Established in 2020 as a spinoff from the University of New South Wales in Canberra, Infinity Avionics not only focuses on the development of optical sensors and computer processors but also offers engineering consulting services directly and through international partnerships. Igor Dimitrijevic, the startup CEO, formerly served as the lead electronics engineer in the university space group.The dual-headed camera system has garnered attention from potential customers, including the Australian Space Command and various international organizations, indicating its potential impact on advancing space surveillance capabilities.

Researchers funded by NASA have received an extraordinary opportunity to seek access to lunar samples collected by China Chang e-5 mission. In a departure from the usual prohibition on bilateral activities, an internal email sent on Nov. 29 revealed that NASA-funded researchers could apply to the China National Space Administration (CNSA) for portions of the Chang e-5 samples.The email stated, "NASA has certified its intent to Congress to allow NASA-funded researchers to apply to the China National Space Administration for access to lunar samples returned to Earth on the Chang e-5 mission and made available recently to the international scientific community for research purposes."This unexpected move opens the door to potential collaboration between China and NASA-funded entities and researchers, contrary to NASA Administrator Bill Nelson previous strong stance against collaboration with China.The "Wolf Amendment," a provision in NASA appropriations bills, typically limits cooperation with entities of the People Republic of China. Collaboration would require prior approval from Congress and certification from the FBI, ensuring no national security risks.China Chang e-5 mission, launched in late 2020, successfully collected 1,731 grams of lunar material from Oceanus Procellarum. Initially made available to Chinese researchers, the samples were later offered to international groups in August. The samples are expected to provide new insights into the moon geological history, complementing NASA existing lunar samples.The email encourages U.S. researchers to apply for the seventh round of sample access, with the application period open until December 22, 2023. Researchers are advised to contact NASA officials for guidance if their applications are selected. However, the email emphasizes that this exception applies solely to the Chang e-5 mission samples, and the general prohibition on bilateral activity with China on NASA-funded projects remains in place.This development has been welcomed by the scientific community, with experts noting the potential for expanding lunar exploration beyond the regions covered by previous missions. James Head, a planetary scientist at Brown University, sees this as an exciting opportunity for future cooperation, possibly extending to missions like China Chang e-6 lunar farside sample return mission in 2024.While the response from CNSA to NASA applications remains uncertain, this rare exception could be a positive step toward international collaboration in space exploration, despite the historical tensions between the U.S. and China in the field.

NASA ambitious Artemis lunar exploration initiative is likely to face a setback, with the first crewed landing expected no earlier than 2027, according to a recent report from the Government Accountability Office (GAO).Released on November 30, the GAO report highlights the sluggish progress on key components of the Artemis program, particularly the Human Landing System (HLS) lunar lander developed by SpaceX and the new lunar spacesuits by Axiom Space. The current target of achieving a crewed landing in late 2025 on the Artemis 3 mission appears unattainable, primarily due to challenges in HLS development.The report underscores SpaceX hurdles, stating that the company "is facing multiple issues that limit this progress and jeopardize its ability to support an Artemis III mission in 2025." These challenges include an ambitious schedule, delays in the current development, and significant technical work.The GAO argues that considering the typical timeline for major projects at NASA, it was unrealistic to expect the Starship lunar lander to be ready by late 2025. "If the HLS development takes as many months as NASA major projects do, on average, the Artemis III mission would likely occur in early 2027," the report notes.SpaceX HLS development is reportedly progressing more slowly than anticipated, with the preliminary design review milestone taking more than half the overall schedule. The report cites SpaceX delays of unspecified key events from 2023 to 2024, compressing the remaining timeline.The GAO report also points to an "incomplete" first integrated test flight of Starship/Super Heavy in April, raising concerns about key technical milestones, including the performance of the Raptor engine and in-space cryogenic propellant transfer.While NASA received an updated schedule for Starship HLS development from SpaceX in August, the details remain undisclosed. NASA officials emphasized ongoing collaboration with SpaceX, stating that the lander integration with the broader program is critical.In addition to SpaceX challenges, the GAO report highlights potential delays in Axiom development of lunar spacesuits. Axiom is still in the early stages of suit development, with a preliminary design review scheduled for November. As of the report date, neither NASA nor Axiom had reported the completion of that review.Axiom plan to redesign portions of the suit based on NASA earlier design to meet agency requirements for 60 minutes of emergency life support capabilities could potentially impede overall spacesuit development. The GAO warns of potential delays, including supply chain challenges with critical components having lead times of 12 to 18 months.

Kayrros, a French provider of satellite imagery analysis, has unveiled a complimentary version of its global methane tracking map on November 29. The aim is to empower the public in holding governments and businesses accountable for their emissions. Leveraging data from the European Space Agency Sentinel-5P satellite and the International Space Station sensor, the platform delivers daily snapshots of methane, a significant contributor to global warming.The map identifies 5,645 methane super-emitters globally, characterized by a notably higher emission rate. Of these, 3,320 are linked to oil and gas, 874 to coal, and 1,451 to waste and agriculture. Notably, the Amman landfill in Jordan is flagged as a major emitter, producing an amount of greenhouse gas equivalent to 450,000 cars annually, despite European Union investments for improved gas capture and electricity generation.Kayrros advocates for an outright ban on super-emitters, asserting that swift reductions in methane emissions from fossil fuels alone could match the impact of removing all cars and trucks from the roads. Addressing major methane emissions is posited as a relatively straightforward method to combat climate change, according to Antoine Rostand, Kayrros president and co-founder.The release of the methane map coincides with the upcoming United Nations Climate Change Conference, COP28, taking place in Dubai between Nov. 30 and Dec. 12. Rostand emphasizes the heightened public awareness and interest in methane reduction, aligning with COP28 focus on the issue.Kayrros also provides access to satellite data through commercial agreements, offering more detailed analyses in paid studies focusing on countries, cities, and individual fields. The United Nations Environment Program International Methane Emissions Observatory is among the entities utilizing Kayrros satellite imagery analysis.Satellite-based tracking of greenhouse gas emissions, involving companies like Canada GHGSat, is seen as a tool to enable scrutiny by institutions, businesses, and investors of emissions reporting. This aligns with the trend of businesses voluntarily disclosing emissions as part of environmental, social, and governance (ESG) disclosures, aiming to attract investors and customers.The public availability of Kayrros methane tracking map is positioned to support efforts in verifying these reports, addressing concerns of greenwashing that have hindered the progress of the ESG movement. Bogdan Gogulan, CEO of NewSpace Capital, a private equity firm and investor in Kayrros, urges diplomats at COP28 to showcase how empirical data will be utilized to drive growth, investment, and financial instruments supporting climate and sustainability technologies. Gogulan emphasizes the importance of precise, traceable, and auditable data for effective climate action, fostering accountability and responsibility. Investors are keenly interested in actionable outcomes from COP28, particularly in the realm of ESG, according to Gogulan.
