Earth planning date: Monday, June 24, 2024

This will be an important week for chemistry on our latest drill sample “Mammoth Lakes 2.”  Curiosity’s primary goal today was a preconditioning of the SAM instrument in preparation for its chemical analysis. Due to the large amounts of power required by SAM, today’s science block was limited to one hour, although it grew a bit at the cost of next sol’s science allocation. Today’s planning only covers one sol (4225), as our usual Wednesday planning day will not have Deep Space Network availability. We will plan 3 sols on Tuesday as a result.

Over the weekend, the “Mammoth Lakes 2” drill sample was dropped off to CheMin for analysis. Mastcam change detection observations of “Walker Pass 2” and “Finch Lake” were begun and will complete on Sol 4225. Remote science on “Whitebark Pass,” “Quarry Peak,” “Broken Finger Peak,” and “Shout of Relief Pass” completed successfully.  On Sol 4225, the focus for remote science was a ChemCam laser spectroscopic characterization and Mastcam imaging of “Horsetail Falls,” an area near the edge of the “Whitebark Pass” workspace slab. The Navcam image below shows the rough surface of “Horsetail Falls” as a stripe of dark rubbly material near the top just right of center edge of the light colored “Whitebark Pass” slab. “Horsetail Falls” is an example of bedrock texture diversity. This target is named for an iconic 270 ft waterfall emerging from Agnew Lake and easily seen from the June Lake Loop road.  “Shout of Relief Pass” honors the 11000 ft pass on the Sierra High Route trail which is a gateway to much easier terrain for the next 25 miles of the trail. All targets in this area of Mount Sharp are named after the Bishop geological quadrangle in the High Sierra and Owens Valley of California. ChemCam RMI will also image an 11×1 mosaic of the nearby channel floor where there are interesting color variations.  Atmospheric observations in this science block consist of a dust devil survey.  In the next plan, SAM will complete its initial analysis. Based on the SAM and CheMin results, the team will then decide whether to do more chemistry at this intriguing location or continue our drive up Mount Sharp.

Unity in Orbit: Astronauts Soar with Pride Aboard Station 

A powerful symbol of pride waved high above Earth aboard the International Space Station in December 2021, reflecting NASA’s commitment to a collaborative and inclusive environment in human spaceflight. The Pride flag was unveiled by NASA astronauts to celebrate our identities and unite in our commitment to equality and acceptance for all individuals. 

At NASA’s Johnson Space Center in Houston, leveraging diverse talents is key to achieving the ambitious goals of space exploration.  

Johnson supports its employees by standing in solidarity and providing resources such as the Out & Allied Employee Resource Group that recognize the unique strengths of the LGBTQI+ workforce and encourage individuals to bring their authentic selves to the workplace. That support extends all the way to low Earth orbit and beyond.

NASA astronaut Raja Chari, as a flight engineer for Expedition 66, captured a monumental image of the Pride flag flowing freely aboard the orbiting laboratory inside the Cupola. 

“As government astronauts, we explore on behalf of all humankind,” said Chari. “Whether it’s on the International Space Station or developing the Artemis vehicles that will take us back to the Moon, it’s NASA’s goal to make space accessible to everyone.” 

Reflecting on his experiences aboard the space station, Chari expressed gratitude for the global support network that supported him along the way. “Nothing I did in space would have been possible without leveraging the diversity of thought that makes human spaceflight possible,” he said. 

At Johnson, the Progress Pride flag was proudly flown in front of building 1 in June 2022, symbolizing the center’s commitment to embracing and recognizing the unique talents of all its employees.

Chari also stressed the importance of diverse perspectives in overcoming the technical challenges of space exploration. “Every day I’m in meetings and testing events where we are tasked with the very real technical challenges of sustaining humans on the Moon and eventually Mars,” he said. “There is no way we will solve the problems on or off our planet if we don’t take advantage of having the most diverse team we can to ensure we don’t overlook a possible solution.” 

“Being in the Cupola with the Pride flag was a way to thank and encourage people to be proud of who they are, and bring their whole selves to work, because we’ll need all of them to get back to the Moon.”

Six Adapters for Crewed Artemis Flights Tested, Built at NASA Marshall

Six Adapters for Crewed Artemis Flights Tested, Built at NASA Marshall

Key adapters for the first crewed Artemis missions are manufactured at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The cone-shaped payload adapter, left, will debut on the Block 1B configuration of the SLS rocket beginning with Artemis IV, while the Orion stage adapters, right, will be used for Artemis II and Artemis III.
Six adapters for the next of NASA’s SLS (Space Launch System) rockets for Artemis II through Artemis IV are currently at NASA’s Marshall Space Flight Center in Alabama. Engineers are analyzing data and applying lessons learned from extensive in-house testing and the successful uncrewed Artemis I test flight to improve future iterations of the rocket.

As a child learning about basic engineering, you probably tried and failed to join a square-shaped toy with a circular-shaped toy: you needed a third shape to act as an adapter and connect them both together. On a much larger scale, integration of NASA’s powerful SLS (Space Launch System) rocket and the Orion spacecraft for the agency’s Artemis campaign would not be possible without the adapters being built, tested, and refined at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Marshall is currently home to six adapters designed to connect SLS’s upper stages with the core stages and propulsion systems for future Artemis flights to the Moon.

Preparing Block 1 Adapters for Upcoming Crewed Flights

The first three Artemis flights use the SLS Block 1 rocket variant, which can send more than 27 metric tons (59,500 pounds) to the Moon in a single launch with the assistance of the interim cryogenic propulsion stage. The propulsion stage is sandwiched between two adapters: the launch vehicle stage adapter and the Orion stage adapter.

The cone-shaped launch vehicle stage adapter provides structural strength and protects the rocket’s flight computers and other delicate systems from acoustic, thermal, and vibration effects.

“The inside of the launch vehicle stage adapter for the SLS rocket uses orthogrid machining – also known as waffle pattern machining,” said Keith Higginbotham, launch vehicle stage adapter hardware manager supporting the SLS Spacecraft/Payload Integration & Evolution Office at Marshall. “The aluminum alloy plus the grid pattern is lightweight but also very strong.”

The launch vehicle stage adapter for Artemis II is  at Marshall and ready for shipment to NASA’s Kennedy Space Center in Florida, while engineering teams are completing outfitting and integration work on the launch vehicle stage adapter for Artemis III. These cone-shaped adapters differ from their Artemis I counterpart, featuring additional avionics protection for crew safety.

Just a few buildings over, the Orion stage adapter for Artemis II, with its unique docking target that mimics the target on the interim cryogenic propulsion stage to test Orion’s handling during the piloting demonstration test, is in final outfitting prior to shipment to Kennedy for launch preparations. The five-foot-tall, ring-shaped adapter is small but mighty: in addition to having space to accommodate small secondary payloads, it contains a diaphragm that acts as a barrier to prevent gases generated during launch from entering Orion.

The Artemis III Orion stage adapter’s major structure is complete and its avionics unit and diaphragm will be installed later this year.  

Block 1B Adapters Support Bolder Missions

Beginning with Artemis IV, a new configuration of SLS, the SLS Block 1B, will use the new, more powerful exploration upper stage to enable more ambitious missions to deep space. The new stage requires new adapters.

The cone-shaped payload adapter – containing two aluminum rings and eight composite panels made from a graphite epoxy material – will be housed inside the universal stage adapter atop the rocket’s exploration upper stage.

The payload adapter test article is being twisted, shaken, and placed under extreme pressure to check its structural strength as part of testing at Marshall. Engineers are making minor changes to the design of the flight article, such as the removal of certain vent holes, based on the latest analyses.

The sixth adapter at Marshall is a development test article of the universal stage adapter, which will be the largest composite structure from human spaceflight missions ever flown at 27.5 feet in diameter and 32 feet long. It is currently undergoing modal and structural testing to ensure it is light, strong, and ready to connect SLS Block 1B’s exploration upper stage to Orion.

“Every pound of structure is equal to a pound of payload,” says Tom Krivanek, universal stage adapter sub-element project manager at NASA’s Glenn Research Center in Cleveland. Glenn manages the adapter for the agency. “That’s why it’s so valuable that the universal stage adapter be as light as possible. The universal stage adapter separates after the translunar insertion, so NASA will need to demonstrate the ability to separate cleanly in orbit in very cold conditions.”

The Future of Marshall Is Innovation

With its multipurpose testing equipment, innovative manufacturing processes, and large-scale integration facilities, Marshall facilities and capabilities enable teams to process composite hardware elements for multiple Artemis missions in parallel, providing for cost and schedule savings.

Lessons learned from testing and manufacturing hardware for the first three SLS flights in the Block 1 configuration have aided in designing and integrating the SLS Block 1B configuration.

“NASA learns with every iteration we build. Even if you have a room full of smart people trying to foresee everything in the future, production is different from development. It’s why NASA builds test articles and doesn’t just start with the flight article as the first piece of hardware.”

Brent Gaddes

Both adapters for the SLS Block 1 are manufactured using friction stir welding in Marshall’s Materials and Processes Laboratory, a process that very reliably produces materials that are typically free of flaws.  

Pioneering techniques such as determinant assembly and digital tooling ensure an efficient and uniform manufacturing process and save NASA and its partners money and time when building Block 1B’s payload adapter. Structured light scanning maps each panel and ring individually to create a digital model informing technicians where holes should be drilled.

“Once the holes are put in with a hand drill located by structured light, it’s simply a matter of holding the pieces together and dropping fasteners in place,” Gaddes said. “It’s kind of like an erector set.”

From erector sets to the Moon and beyond – the principles of engineering are the same no matter what you are building.

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

By Derek Koehl

Collaborations with private, non-federal partners through Space Act Agreements are a key component in the work done by NASA’s Interagency Implementation and Advanced Concepts Team (IMPACT). A collaboration with International Business Machines (IBM) has produced INDUS, a comprehensive suite of large language models (LLMs) tailored for the domains of Earth science, biological and physical sciences, heliophysics, planetary sciences, and astrophysics and trained using curated scientific corpora drawn from diverse data sources.

INDUS contains two types of models; encoders and sentence transformers. Encoders convert natural language text into numeric coding that can be processed by the LLM. The INDUS encoders were trained on a corpus of 60 billion tokens encompassing astrophysics, planetary science, Earth science, heliophysics, biological, and physical sciences data. Its custom tokenizer developed by the IMPACT-IBM collaborative team improves on generic tokenizers by recognizing scientific terms like biomarkers and phosphorylated. Over half of the 50,000-word vocabulary contained in INDUS is unique to the specific scientific domains used for its training. The INDUS encoder models were used to fine tune the sentence transformer models on approximately 268 million text pairs, including titles/abstracts and questions/answers.

By providing INDUS with domain-specific vocabulary, the IMPACT-IBM team achieved superior performance over open, non-domain specific LLMs on a benchmark for biomedical tasks, a scientific question-answering benchmark, and Earth science entity recognition tests. By designing for diverse linguistic tasks and retrieval augmented generation, INDUS is able to process researcher questions, retrieve relevant documents, and generate answers to the questions. For latency sensitive applications, the team developed smaller, faster versions of both the encoder and sentence transformer models.

Validation tests demonstrate that INDUS excels in retrieving relevant passages from the science corpora in response to a NASA-curated test set of about 400 questions. IBM researcher Bishwaranjan Bhattacharjee commented on the overall approach: “We achieved superior performance by not only having a custom vocabulary but also a large specialized corpus for training the encoder model and a good training strategy. For the smaller, faster versions, we used neural architecture search to obtain a model architecture and knowledge distillation to train it with supervision of the larger model.”

INDUS was also evaluated using data from NASA’s Biological and Physical Sciences (BPS) Division. Dr. Sylvain Costes, the NASA BPS project manager for Open Science, discussed the benefits of incorporating INDUS: “Integrating INDUS with the Open Science Data Repository  (OSDR) Application Programming Interface (API) enabled us to develop and trial a chatbot that offers more intuitive search capabilities for navigating individual datasets. We are currently exploring ways to improve OSDR’s internal curation data system by leveraging INDUS to enhance our curation team’s productivity and reduce the manual effort required daily.”

At the NASA Goddard Earth Sciences Data and Information Services Center (GES-DISC), the INDUS model was fine-tuned using labeled data from domain experts to categorize publications specifically citing GES-DISC data into applied research areas. According to NASA principal data scientist Dr. Armin Mehrabian, this fine-tuning “significantly improves the identification and retrieval of publications that reference GES-DISC datasets, which aims to improve the user journey in finding their required datasets.” Furthermore, the INDUS encoder models are integrated into the GES-DISC knowledge graph, supporting a variety of other projects, including the dataset recommendation system and GES-DISC GraphRAG.

Kaylin Bugbee, team lead of NASA’s Science Discovery Engine (SDE), spoke to the benefit INDUS offers to existing applications: “Large language models are rapidly changing the search experience. The Science Discovery Engine, a unified, insightful search interface for all of NASA’s open science data and information, has prototyped integrating INDUS into its search engine. Initial results have shown that INDUS improved the accuracy and relevancy of the returned results.”

INDUS enhances scientific research by providing researchers with improved access to vast amounts of specialized knowledge. INDUS can understand complex scientific concepts and reveal new research directions based on existing data. It also enables researchers to extract relevant information from a wide array of sources, improving efficiency. Aligned with NASA and IBM’s commitment to open and transparent artificial intelligence, the INDUS models are openly available on Hugging Face. For the benefit of the scientific community, the team has released the developed models and will release the benchmark datasets that span named entity recognition for climate change, extractive QA for Earth science, and information retrieval for multiple domains. The INDUS encoder models are adaptable for science domain applications, and the INDUS retriever models support information retrieval in RAG applications.

A paper on INDUS, “INDUS: Effective and Efficient Language Models for Scientific Applications,” is available on arxiv.org.

Gateway: Up Close in Stunning Detail

A detailed 3D animation of NASA's Gateway space station, showcasing its modules and structural components from various angles against the backdrop of deep space.
NASA/Bradley Reynolds, Alberto Bertolin

NASA and its international partners will explore the scientific mysteries of deep space with Gateway, humanity’s first space station to orbit the Moon. Starting with the Artemis IV mission in 2028, the international teams of astronauts living, conducting science, and preparing for missions to the lunar South Pole region on Gateway will be the first humans to make their home in deep space.

This artist’s computer-generated animation presents an exterior tour of Gateway in stunning detail. Depicted Gateway elements are the:

  • Power and Propulsion Element that will make Gateway the most powerful solar electric spacecraft ever flown. The module will use the Sun’s energy to power the space station’s subsystems and ionize xenon gas to produce the thrust that will maintain Gateway’s unique polar orbit around the Moon.
  • HALO (Habitation and Logistics Outpost), Gateway’s command and control nexus providing communications between Earth and the lunar surface with the Lunar Link system provided by ESA (European Space Agency). HALO will house life support systems, including exercise equipment, and science payload banks.
  • Lunar I-Hab, provided by ESA with hardware contributions from JAXA (Japan Aerospace Exploration Agency), will host environmental control and life support systems, sleeping quarters, and a galley, among other features.
  • Lunar View, provided by ESA, will have refueling capabilities for the Power and Propulsion Element, cargo storage, and large windows.
  • Crew and Science Airlock, provided by the Mohammad Bin Rashid Space Centre of the United Arab Emirates, for crew and hardware transfer from Gateway’s interior to the vacuum of space.
  • Canadarm3 advanced external robotic system provided by CSA (Canadian Space Agency).
  • Deep Space Logistics spacecraft that will transport cargo to Gateway to support Artemis missions.
  • Initial Gateway science payloads that will study solar and cosmic radiation, a little-understood phenomenon that is a chief concern for people and hardware traveling through deep space, including Mars. The payloads visible in this video are ERSA (European Radiation Sensors Array), provided by ESA, attached to the Power and Propulsion Element, and the NASA-led HERMES (Heliophysics Environmental and Radiation Measurement Experiment Suite) is attached to HALO. A third radiation science payload, IDA (Internal Dosimeter Array), provided by ESA and JAXA, will be inside of HALO.

This video also depicts:

  • The Orion spacecraft docked to the Crew and Science Airlock. Orion will transport international teams of astronauts and three modules (Lunar I-Hab, Lunar View and the Crew and Science Airlock) to the Gateway space station.
  • Government-reference Human Landing System (HLS) that will ferry astronauts to and from the lunar South Pole region. SpaceX and Blue Origin are on contract to provide the Starship HLS and Blue Moon HLS, respectively.

Gateway is part of the Artemis architecture to return humans to the lunar surface for scientific discovery and chart a path for human exploration further into the solar system, such as to Mars and beyond.

Johnson Celebrates LGBTQI+ Pride Month: Eva Granger

Eva Granger firmly believes that anyone can launch a career at NASA. As the events and milestones lead for the Orion Program’s strategic communications team, she dedicates her time to engaging with the public and educating them not only about the Orion spacecraft but also about the various opportunities to contribute to the agency’s mission.

“I have met so many people who don’t think aerospace is possible for them, but it’s easy to clear up that assumption. There are artists, nurses, psychologists, administrative assistants, and more working at NASA,” she said. “There are opportunities for everyone to build a life and career here, and telling someone that, and seeing something spark, is always rewarding.”

When Granger started working as a full-time contractor in October 2023 at Johnson Space Center in Houston, she was already familiar with her role. An internship in 2022 gave her experience with the program’s event planning and coordination, as well as an exciting opportunity to support and staff the Artemis I launch at NASA’s Kennedy Space Center in Florida.

“During those few days, I met individuals who flew from all over the world to watch the launch. The commitment and excitement that I felt from the global audience was tangible, and impressed on me the importance and impact of the work we do,” she said. “It’s one thing to know the world is watching, but it’s a whole different experience to meet them and be told they’re rooting for your program.”

Granger is an active member of Johnson’s Out & Allied Employee Resource Group (ERG) and is currently working to organize the group’s participation in the Houston Pride Parade. “We want to have fun with the parade, but it also gives us an avenue to put together an event that is visible and that anyone at Johnson can attend and be excited about together,” she said.

She believes that continually being present and engaged is the best way to support and champion an equitable and inclusive environment. “The ERG has been amazing in giving us a structured opportunity to make a difference,” she said. “If we show up at the JSC Chili Cookoff or at intern events, people know that we’re here. It shows our closeted friends that there is a support network here at Johnson, and it allows the greater Johnson community to learn about our group and engage with us.”

The ERG also provides valuable professional development resources and networking opportunities. “As a young professional, it is crucial to have mentors, and Out & Allied is full of people who are excited to spend their time building up our members and our community,” Granger said.

She encourages colleagues to connect with others outside their usual social and professional circles as a way to support diversity and inclusion. “There are hundreds of people on campus and all of them have something interesting to share if you stop and say hi,” she said. “Little interactions go a long way.”
