Reaching New Heights to Unravel Deep Martian History!
This is an image of the rim that the Perseverance rover took on sol 383 (March 19th, 2022) when it was traversing the crater floor. Dox Castle is located at the top of the image in the far ground. NASA/JPL-Caltech/ASU The Perseverance rover is reaching new heights as it ascends the rim of Jezero crater (over 300 meters in elevation higher than the original landing site)! The rover is now enroute to its first campaign science stop Dox Castle (image in the far ground) a region of interest for its potential to host ancient Mars’ bedrock in the exposed rocks on the rim.
Impact craters like Jezero may be the key to piecing together the early geologic history of Mars, as they provide a window into the history of the ancient crust by excavating and depositing deep crustal materials above the surface. Crater rims act as keepers of ancient Martian history, uplifting and exposing the stratigraphy of these impacted materials. Additionally, extreme heat from the impact can encourage the circulation of fluids through fractures similar to hydrothermal vents, which have implications for early habitability and may be preserved in the exposed rim bedrock. With the Perseverance rover we have the potential to explore some of the oldest exposed rocks on the planet.
Exploring such diverse terrains takes a lot of initial planning! The team has been preparing for the Crater Rim Campaign these last few months by working together to map out the types of materials Perseverance may encounter during its traverse up and through the rim. Using orbital images from the High-Resolution Imaging Science Experiment (HiRISE) instrument, the science team divided the rim area into 36 map quadrants, carefully mapping different rock units based on the morphologies, tones, and textures they observed in the orbital images. Mapping specialists then connected units across the quads to turn 36 miniature maps into one big geologic map of the crater rim. This resource is being used by the team to plan strategic routes to scientific areas of interest on the rim.
On Earth, geologic maps are made using a combination of orbital images and mapping in the field. Planetary scientists don’t typically get to check their map in the field, but we have the unique opportunity to validate our map using our very own robot geologist! Dox Castle will be our first chance to do rim science – and we’re excited to search for evidence of the transition between the margin and rim materials to start piecing together the stratigraphic history of the rocks that make up the rim of Jezero crater.

Manuel Retana arrived in the U.S. at 15 years old, unable to speak English and with nothing but a dream and $200 in his pocket. Now, he plays a crucial role implementing life support systems on spacecraft that will carry humans to the Moon and, eventually, Mars—paving the way for the next frontier of space exploration.
A project manager for NASA’s Johnson Space Center Life Support Systems Branch in Houston, Retana helps to ensure astronaut safety aboard the International Space Station and for future Artemis missions. His work involves tracking on-orbit technical issues, managing the cost and schedule impacts of flight projects, and delivering emergency hardware.
Manuel Retana stands in front of NASA’s Space Launch System rocket at Kennedy Space Center in Florida. One of his most notable achievements came during the qualification of the Orion Smoke Eater Filter for the Artemis II and III missions. The filter is designed to remove harmful gases and particulates from the crew cabin in the event of a fire inside the spacecraft. Retana was tasked with creating a cost-effective test rig – a critical step for making the filter safe for flight.
Retana’s philosophy is simple: “Rockets do not build themselves. People build rockets, and your ability to work with people will define how well your rocket is built.”
Throughout his career, Retana has honed his soft skills—communication, leadership, collaboration, and conflict resolution—to foster an environment of success.
Retana encourages his colleagues to learn new languages and share their unique perspectives. He even founded NASA’s first Mariachi ensemble, allowing him to share his cultural heritage in the workplace.
He believes diversity of thought is a key element in solving complex challenges as well as creating an environment where everyone feels comfortable sharing their perspectives.
“You need to be humble and have a willingness to always be learning,” he said. “What makes a strong team is the fact that not everyone thinks the same way.”
Manuel Retana, center, performs with the Mariachi Ensemble group at NASA’s Johnson Space Center in Houston. For the future of space exploration, Retana is excited about the democratization of space, envisioning a world where every country has the opportunity to explore. He is eager to see humanity reach the Moon, Mars, and beyond, driven by the quest to answer the universe’s most enigmatic questions.
To the Artemis Generation, he says, “Never lose hope, and it is never too late to start following your dreams, no matter how far you are.”

NASA Deputy Associate Administrator Casey Swails examines a sample of algae through a microscope in the Space Biosciences Research Lab. Swails, alongside Director of Cross Agency Strategy Integration John Keefe and Associate Administrator Jim Free, toured the NASA Ames campus on Aug. 28.NASA/Donald Richey NASA Associate Administrator Jim Free, Deputy Associate Administrator Casey Swails, and Director of Cross-Agency Strategy John Keefe visited NASA’s Ames Research Center in California’s Silicon Valley on Aug. 28. The visit was an opportunity for the leaders to meet with center leadership and tour multiple Ames facilities. Free, Swails, and Keefe also met with employees to discuss the agency’s strategic initiative, NASA 2040, a strategic agency initiative aimed at driving meaningful changes that will allow the agency to realize its long-term vision for what leaders and employees want the agency to be in 2040 and beyond.
During their tour, researchers at the Space Biosciences Research Lab presented on innovative projects like the Lunar Explorer Instrument for space biology Applications, an instrument that will study how yeast reacts to the lunar environment. The three leaders also learned about innovative wildfire research and other projects that seek to advance space exploration through scientific discoveries and technical developments.
The group ended their tour by visiting NASA Research Park tenants like the USGS National Innovation Center, and viewing the proposed future site of the UC Berkeley Space Center, a 36-acre campus and innovation hub for research and advancements in aeronautics, quantum computing, climate studies, social sciences, and more.

As a Human Resource Business Partner at NASA Headquarters, Selina Salgado describes her job as helping with “all things people” for the enterprise. By facilitating technological solutions to human resources (HR) challenges and needs, she excels at an often-underestimated aspect of Digital Transformation (DT): the interpersonal side. As a champion of community building, knowledge sharing, and digital upskilling, Selina was an easy selection for this month’s Digital Transformer award.
Selina started at NASA in 2019 as a Pathways intern and previously worked as a mentoring coordinator for Marshall Space Flight Center (MSFC), which is where her Digital Transformation journey began. At MSFC, she created an all-in-one, automated system for open job postings, which decreased the agency’s time to hire and increased visibility for available positions. She has aspirations for further leveraging these types of systems to improve inclusive teaming across NASA by making HR tools available and interoperable across centers. Her current team under the Office of the Chief Human Capital Officer (OCHCO) operates with an 80-20 mentality, working to create common tools and solutions that are 80% interoperable and 20% customizable to the specific organization or scenario.
In addition to her technical work on digital HR tools like the automated job board, Selina takes initiative to help people understand what transformation means to them and how to practice transformation in their daily lives. In collaboration with Jess Deibert, DT Digital Academy Lead, Selina created the new Transformation Tips (TxTips) series, which features NASA employees’ tech-related tips for doing their work. The instant popularity of the community-led series led to speaker requests for TxTip presentations from several other offices at NASA, including the Office of STEM Engagement.
Most recently, Selina has become a key contributor and partner in NASA’s Summer of AI upskilling campaign to help employees maximize the benefits of AI while managing risks. As a self-taught developer, Selina has created several tools and apps to streamline agency-wide collaboration and data collection. She leveraged PowerApps, Power Automate, and Power BI, integrated with SharePoint, to feed data to a dashboard used by the Agency Chief AI Officer to brief the Administrator on impact metrics from the Summer of AI campaign. Selina also developed and executed several events to engage and excite the workforce around this campaign, including conceiving the agency’s first “Battle of the Bots” event. Her Reddit-style “Ask Me Anything” event helped employees understand the differences in large language models by pitting ChatGPT against Microsoft CoPilot to respond to participant-submitted prompts and questions. The Battle of the Bots saw the highest engagement of any asynchronous Summer of AI event.
Selina’s educational background aligns with her focus on the connective and collaborative aspects of Digital Transformation. She received her bachelor’s degree in business management with a focus in human resource management and her master’s degree in education and student affairs, which led to her interest in NASA’s internship and mentorship programs. The connection piece, she says, is what she enjoys most about collaborating with DT. “If you run into an issue, there’s a community of practice out there for you to reach out to and engage with…to build that network with other employees that are interested in and passionate about transformation.”
The other influence Selina points to along her Digital Transformation journey is her military background. “I grew up in a military household, and then I joined the Navy right out of high school. There’s a culture there of how to get things done,” says Selina. “What drives my passion for processes and systems is that it’s transferrable to somebody else…I need to be able to pass that on to the next person.” She gets energized by learning new tools and finding solutions to roadblocks, especially when she can establish procedures for others to leverage and build on her work. “That’s something that I love about transformation and just change in general—that you get to develop and learn and connect with new people.”
If there’s one message Selina hopes to spread at NASA through her achievements as a Digital Transformer, it’s that Digital Transformation is for everyone. “You don’t have to be in IT, you don’t have to have that background or technical [ability],” she says. “I mean, I’m in HR. Any field at NASA can utilize the digital landscape and digital transformation. Those principles and resources are available for everybody.”
