NASA Goddard MODIS Rapid Response Team During the morning of March 20, 2015, a total solar eclipse was visible from parts of Europe, and a partial solar eclipse from northern Africa and northern Asia. NASA’s Terra satellite passed over the Arctic Ocean on March 20 at 10:45 UTC (6:45 a.m. EDT) and captured the eclipse’s shadow over the clouds in the Arctic Ocean.
Terra launched 25 years ago on Dec. 18, 1999. Approximately the size of a small school bus, the Terra satellite carries five instruments that take coincident measurements of the Earth system: Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Clouds and Earth’s Radiant Energy System (CERES), Multi-angle Imaging Spectroradiometer (MISR), Measurements of Pollution in the Troposphere (MOPITT), and Moderate Resolution Imaging Spectroradiometer (MODIS).
On Nov. 28, 2024, one of Terra’s power-transmitting shunt units failed. A response team reviewed Terra’s status and discussed potential impacts and options. Consequently, the team placed ASTER into Safe Mode. As a result, ASTER data are not currently being collected. All other instruments continue uninterrupted.

Credit: NASA Two proposals for missions to observe X-ray and far-infrared wavelengths of light from space were selected by NASA for additional review, the agency announced Thursday. Each proposal team will receive $5 million to conduct a 12-month mission concept study. After detailed evaluation of those studies, NASA expects to select one concept in 2026 to proceed with construction, for a launch in 2032.
The resulting mission will become the first in a new class of NASA astrophysics missions within the agency’s longstanding Explorers Program. The new mission class, Probe Explorers, will fill a gap between flagship and smaller-scale missions in NASA’s exploration of the secrets of the universe.
“NASA’s Explorers Program brings out some of the most creative ideas for missions that help us reveal the unknown about our universe. Establishing this new line of missions – the largest our Astrophysics program has ever competed – has taken that creativity to new heights,” said Nicola Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Both of the selected concepts could enable ground-breaking science responsive to the top astrophysics priorities of the decade, develop key technologies for future flagship missions, and offer opportunities for the entire community to use the new observatory, for the benefit of all.”
The National Academies of Sciences, Engineering, and Medicine’s 2020 Decadal Survey, Pathways to Discovery in Astronomy and Astrophysics for the 2020s, recommended NASA establish this new mission class, with the first mission observing either X-ray or far-infrared wavelengths of light. Mission costs for the new Probe Explorers are capped at $1 billion each, not including the cost of the rocket, launch services, or any contributions.
NASA evaluated Probe Explorers proposals based on their scientific merit in alignment with the Decadal Survey’s recommendations, feasibility of development plans, and use of technologies that could support the development of future large missions.
The selected proposals are:
Advanced X-ray Imaging Satellite
This mission would be an X-ray imaging observatory with a large, flat field-of-view and high spatial resolution. It would study the seeds of supermassive black holes; investigate the process of stellar feedback, which influences how galaxies evolve; and help determine the power sources of a variety of explosive phenomena in the cosmos. The observatory would build on the successes of previous X-ray observatories, capturing new capabilities for X-ray imaging and imaging spectroscopy. Principal investigator: Christopher Reynolds, University of Maryland, College Park Project management: NASA’s Goddard Space Flight Center in Greenbelt, Maryland Probe far-Infrared Mission for Astrophysics
This observatory would be a 5.9-foot (1.8-meter) telescope studying far-infrared wavelengths, helping bridge the gap between existing infrared observatories, such as NASA’s James Webb Space Telescope, and radio telescopes. By studying radiant energy that only emerges in the far-infrared, the mission would address questions about the origins and growth of planets, supermassive black holes, stars, and cosmic dust. Principal investigator: Jason Glenn, NASA Goddard Project management: NASA’s Jet Propulsion Laboratory in Southern California The Explorers Program is the oldest continuous NASA program designed to provide frequent, low-cost access to space using principal investigator-led space science investigations relevant to the Science Mission Directorate’s astrophysics and heliophysics programs. Since the Explorer 1 launch in 1958, which discovered Earth’s radiation belts, the Explorers Program has launched more than 90 missions, including the Uhuru and Cosmic Background Explorer missions that led to Nobel prizes for their investigators.
The Explorers Program is managed by NASA Goddard for the Science Mission Directorate, which conducts a wide variety of research and scientific exploration programs for Earth studies, space weather, the solar system and universe.

Software plays a key role in high-risk systems, e.g., safety-, and security-critical systems. Several certification standards/guidelines now recommend and/or mandate the development of assurance cases for software-intensive systems, e.g., defense (UK MoD DS-0056), aviation (CAP 670. FAA operational approval guidance for unmanned aircraft systems), automotive (ISO 26262), and healthcare (FDA infusion pumps total product lifecycle guidance). As such, there is a need to develop models, techniques and tools that target the development of assurance arguments for software.
The goals of the 2015 Workshop on Assurance Cases for Software-intensive Systems (ASSURE 2015) are to:
explore techniques for creating/assessing assurance cases for software-intensive systems; examine the role of assurance cases in the engineering lifecycle of critical systems; identify the dimensions of effective practice in the development and evaluation of assurance cases; investigate the relationship between dependability techniques and assurance cases; and, identify critical research challenges and define a roadmap for future development. We solicit high-quality contributions: research, practice, tools and position papers on the application of assurance case principles and techniques to assure that the dependability properties of critical software-intensive systems have been met.
Papers should attempt to address the workshop goals in general.
Topics
Topics of interest include, but are not limited to:
Standards: Industry guidelines and standards are increasingly requiring the development of assurance cases, e.g., the automotive standard ISO 26262 and the FDA guidance on the total product lifecycle for infusion pumps. Certification and Regulations: The role and usage of assurance cases in the certification of critical systems, as well as to show compliance to regulations. Dependable architectures: How do fault-tolerant architectures and design measures such as diversity and partitioning relate to assurance cases? Dependability analysis: What are the relationships between dependability analysis techniques and the assurance case paradigm? Tools: Using the output from software engineering tools (testing, formal verification, code generators) as evidence in assurance cases / using tools for the modeling, analysis and management of assurance cases. Application of formal techniques to create and analyze arguments. Exploration of relevant techniques for assurance cases for real-time, concurrent, and distributed systems. Assurance issues in emerging computational paradigms, e.g., cloud, mobile, virtual, many-core architectures, and adaptive and autonomous systems. Modeling and Metamodeling: Representation of structured arguments through metamodels, such as OMG’s Structured Assurance Case Metamodel (SACM). Assurance of software quality attributes, e.g., safety, security and maintainability, as well as dependability in general, including tradeoffs, and exploring notions of the quality of assurance cases themselves. Domain-specific assurance issues, in domains such as aerospace, automotive, healthcare, defense and power. Reuse and Modularization: Contracts and patterns for improving the reuse of assurance case structures. Connections between the Goal Structuring Notation for assurance cases, and goal-orientation from the requirements engineering community. Submit

Credit: NASA NASA has selected three additional companies to provide launch services for future agency missions through its VADR (Venture-Class Acquisition of Dedicated and Rideshare) contract.
The companies awarded are:
Arrow Science and Technology LLC of Webster, Texas Impulse Space Inc. of Redondo Beach, California Momentus Space LLC of San Jose, California The VADR contract is a firm-fixed-price, indefinite-delivery/indefinite-quantity instrument with an ordering period through Feb. 3, 2027 and a maximum total value of $300 million across all VADR contracts. NASA selected the new launch providers in accordance with VADR’s on-ramp provision, allowing the agency to add new capabilities not available or identified at the time of the initial award. NASA will issue firm-fixed-price task orders for launch services as needed for future agency and agency-sponsored missions.
The VADR contract builds on NASA’s previous procurement efforts, such as the VCLS (Venture Class Launch Services) and VCLS Demo 2, providing a broad range of Federal Aviation Administration-licensed commercial launch services capable of delivering Class D, CubeSats, and higher risk-tolerant payloads to a variety of orbits. By using a lower level of mission assurance and commercial best practices for launching rockets, these highly flexible contracts help broaden access to space through lower launch costs and serve as an ideal platform for contributing to NASA’s science research and technology development.
NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contracts. The program also works with private industry, spacecraft projects, and international partners to launch science payloads ranging from small satellites with colleges and universities to NASA’s highest priority missions.
