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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
As students head back to school, teachers have a new tool that brings NASA satellite data down to their earthly classrooms.
The My NASA Data homepage categorizes content by areas of study called spheres and also Earth as a system. NASA/mynasadata.larc.nasa.gov For over 50 years of observing Earth, NASA’s satellites have collected petabytes of global science data (that’s millions and millions of gigabytes) – with terabytes more coming in by the day. Since 2004, the My NASA Data website has been developing ways for students and teachers of grades 3-12 to understand, and visualize NASA data, and to help incorporate those measurements into practical science lessons.
“We have three different types of lesson plans, some of which are student-facing and some are teacher-facing,” said Angie Rizzi, My NASA Data task lead, based at NASA’s Langley Research Center in Hampton, Virginia. “Teachers can download complete lesson plans or display a wide variety of Earth data. There are also lessons written for students to interact with directly.”
An image from My NASA Data’s Earth System Data Explorer visualization tool showing the monthly leaf index around the world as measured by NASA satellites in August 2020. Data parameters for this visualization were set to biosphere under the sphere dropdown and vegetation as a category. NASA/mynasadata.larc.nasa.gov A key component of the My NASA Data site is the newly updated Earth System Data Explorer visualization tool, which allows users to access and download NASA Earth data. Educators can explore the data then create custom data tables, graphs, and plots to help students visualize the data. Students can create and investigate comparisons between land surface temperatures, cloud cover, extreme heat, and a wide range of other characteristics for a specific location or region around the globe.
An image from My NASA Data’s visualization tool showing various searchable categories under the atmosphere dataset selection. NASA/mynasadata.larc.nasa.gov “The Earth System Data Explorer tool has a collection of science datasets organized by different spheres of the Earth system,” explained Desiray Wilson, My NASA Data scientific programmer. The program highlights six areas of study: atmosphere, biosphere, cryosphere, geosphere, hydrosphere, and Earth as a system. “The data goes as far back as the 1980s, and we are getting more daily datasets. It’s really good for looking at historical trends, regional trends, and patterns.”
My NASA Data had over one million site visits last year, with some of the most popular searches focusing on temperatures, precipitation, water vapor, and air quality.
My NASA Data program leaders and instructors collaborating with educators from the North Carolina Space Grant at NASA’S Langley Research Center June 26, 2024. Teachers were at NASA Langley as part of the North Carolina Space Education Ambassadors (NCSEA) program and were given demonstrations of the My NASA Data website. NASA/David C. Bowman Natalie Macke has been teaching for 20 years and is a science teacher at Pascack Hills High School in Montvale, New Jersey. Teachers like Macke help shape the lessons on the site through internships with the My NASA Data team. Teachers’ suggestions were also incorporated to enhance the visualization tool by adding new features that now allow users to swipe between visual layers of data and make side-by-side comparisons. Users can also now click on a location to display latitude and longitude and variable data streamlining the previous site which required manual input of latitude and longitude.
“The new visualization tool is very much a point-and-click layout like our students are used to in terms of just quickly selecting data they want to see,” said Macke. “Instantaneously, a map of the Earth comes up, or just the outline, and they can get the satellite view. So if they’re looking for a specific city, they can find the city on the map and quickly grab a dataset or multiple datasets and overlay it on the map to make visual comparisons.”

The image below shows the same map layered with atmospheric measurements.NASA/mynasadata.larc.nasa.gov The East Coast of the United States shown with monthly daytime surface (skin) temperatures from August 2023 overlayed from Earth-observing satellite data using the My NASA Data Earth System Data Explorer visualization tool. The image above shows the same region without the data layer added.NASA/mynasadata.larc.nasa.gov/ Even more valuable than creating visualizations for one specific lesson, elaborated Macke, is the opportunity My NASA Data provides for students to understand the importance of interpreting, verifying, and using datasets in their daily lives. This skill, she said, is invaluable, because it helps spread data literacy enabling users to look at data with a discriminating eye and learn to discern between assumptions and valid conclusions.
“Students can relate the data map to literally what’s happening outside their window, showing them how NASA Earth system satellite data relates to real life,” said Macke. “Creating a data literate public – meaning they understand the context and framework of the data they are working with and realizing the connection between the data and the real world – hopefully will intrigue them to continue to explore and learn about the Earth and start asking questions. That’s what got me into science when I was a little kid.”

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.”
