Preparations for Next Moonwalk Simulations Underway (and Underwater)
How to Attend
The workshop will be hosted by NASA Jet Propulsion Laboratory.
Virtual and in-person attendance are available. Registration is required for both. (Link coming soon!)
Virtual attendees will receive connection information one week before the workshop.
Background, Goals and Objectives
The NASA Engineering and Safety Center (NESC) is conducting an assessment of the state of cold capable electronics for future lunar surface missions. The intent is to enable the continuous use of electronics with minimal or no thermal management on missions of up to 20 years in all regions of the lunar surface, e.g., permanently shadowed regions and equatorial. The scope of the assessment includes: capture of the state of cold electronics at NASA, academia, and industry; applications and challenges for lunar environments; gap analyses of desired capabilities vs state of the art/practice; guidance for cold electronics selection, evaluation and qualification; and recommendations for technology advances and follow-on actions to close the gaps. The preliminary report of the assessment will be available the first week of April 2025 on this website, i.e., 3 weeks prior to the workshop. Attendees are urged to read the report beforehand as the workshop will provide only a limited, high-level summary of the report’s key findings. The goal of the workshop is to capture your feedback with regards to the findings of the report, especially in the areas below: Technologies, new or important studies or data that we missed. Gaps, i.e. requirements vs available capabilities that we missed. Additional recommendations, suggestions, requests, that we missed.

One semester as a NASA Pathways intern was enough to inspire Portia Keyes to sign up for a Russian language class at college. After interning in the Johnson Space Center’s Office of Procurement, Keyes hoped to someday use her new language skills in support of the International Space Station Program.
Now, 12 years later, Keyes is the deputy manager of the procurement office for the International Space Station and Commercial Low Earth Orbit Development Programs. That means she is responsible for implementing and overseeing acquisition solutions that enable the purchasing of goods and services in support of both programs.

One of Keyes’ favorite NASA projects involved negotiating a contract modification with Roscosmos to secure transportation of NASA astronauts to the International Space Station via Soyuz spacecraft following the space shuttle’s retirement. “This project stands out to me both for its impact on NASA’s missions and the way it transcended political and geographical boundaries,” Keyes said. Being a part of this effort reinforced the importance of collaboration on a global scale. “It demonstrated how shared goals and values can unite people across different nations, regardless of external circumstances,” she said. “The world is more connected than we often realize.”
Keyes values collaboration on a smaller scale, as well, noting that her procurement role involves working with a wide variety of subject matter experts who are passionate about their respective fields. She acknowledged that procurement staff are sometimes seen as obstructing or slowing a mission rather than enabling it, although she has overcome this challenge through effective communication with stakeholders – striving to understand their perspectives and present mutually beneficial solutions.
“My commitment is to advancing NASA’s missions through the responsible management of taxpayer dollars,” she said. “Collaborating closely with my technical counterparts, I have been able to secure mission-critical services and supplies, all while adhering to regulatory, schedule, and resource constraints.”

Image courtesy of Portia Keyes Adaptability has also been important to Keyes’ success. “Whether it’s shifting priorities due to unforeseen challenges, navigating cultural differences within international teams, or adjusting to new acquisition regulations, being flexible and open to change has allowed me to not just survive in dynamic environments, but thrive,” she said.
At the same time, Keyes strives to maintain balance in the workplace. “What I have learned about myself is that I can do anything, but not everything,” she said. “Maturing in my career has meant accepting that I have limited time, energy, and resources, so it is important to discern what truly matters and focus my efforts there.”
Portia Keyes, fourth from left, received a JSC Director’s Commendation Award in June 2024 for significant contributions to Johnson’s Office of Procurement. From left are Johnson Associate Director for Vision and Strategy Douglas Terrier, Office of Procurement Director Brad Niese, Office of Procurement Functional Lead Candice Palacios-Hoang, Keyes, and Johnson Director Vanessa Wyche.NASA Keyes’ hard work has been recognized with several awards throughout her career. She is proudest of earning the Office of Procurement Bubbee’s Coach Award, which is given to the team member most likely to serve as a mentor to colleagues. “Much of my professional and personal growth has stemmed from formal and informal mentors who supported me in navigating challenges, developing new skills, and creating environments for me to thrive,” she said. “I have a great appreciation for those mentors, and I strive to impact those around me similarly.”
Keyes hopes to encourage the Artemis Generation to approach the future – and periods of uncertainty – with curiosity, resilience, and a responsibility to care for our planet and the universe. She looks forward to the continued expansion of access to space.
“I hope to be around for the days where I can afford a reasonably priced, roundtrip ticket to the Moon,” she said. “Perhaps by then they will sell functional spacesuits in the local sporting goods stores.”

Modeling properties of thunderstorm discharges
Researchers report detailed physical properties of different types of corona discharges, including single- and multi-pulse blue discharges linked to powerful but short-lived electrical bursts near the tops of clouds. These details provide a reference for further investigation into the physical mechanisms behind these discharges and their role in the initiation of lightning, an important problem in lightning physics.
An ESA (European Space Agency) instrument used to study thunderstorms, Atmosphere-Space Interactions Monitor (ASIM) provides insights into their role in Earth’s atmosphere and climate, including mechanisms behind the creation of lightning. Understanding how thunderstorms and lightning disturb the upper atmosphere could improve atmospheric models along with climate and weather predictions. These high-altitude discharges also affect aircraft and spacecraft safety.

Researchers conclude that the space station’s ECOSTRESS instrument yields highly accurate sea surface temperature data. Given the instrument’s global coverage and high spatial resolution, these data have potential use in studies of biological and physical oceanography to evaluate regional and local effects of climate change.
ECOSTRESS resolves oceanographic features not detectable in imagery from NOAA’s Visible Infrared Imaging Radiometer Suite satellite, and has open-ocean coverage, unlike Landsat. Satellites are a fundamental tool to measure sea surface temperatures, which are rising across all oceans due to atmospheric warming induced by climate change.

Researchers report detailed observations and analysis of emissions from an exceptionally bright gamma ray burst (GRB), 210619B, detected by the station’s ASIM and other satellite and ground-based instruments. These observations could be useful in determining various properties of GRBs and how they change during different phases.
Believed to be generated by the collapse of massive stars, GRBs are the brightest, most explosive transient electromagnetic events in the universe. ASIM can observe thunderstorm discharges difficult to observe from the ground. It has a mode where a detected event triggers observation and onboard storage of data.
