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.

Armstrong Operations and Checkout via truck.

Credit: NASA From across the Atlantic Ocean and through the Gulf of Mexico, two ships converged, delivering key spacecraft and rocket components of NASA’s Artemis campaign to the agency’s Kennedy Space Center in Florida.
On Sept. 3, ESA (European Space Agency) marked a milestone in the Artemis III mission as its European-built service module for NASA’s Orion spacecraft completed a transatlantic journey from Bremen, Germany, to Port Canaveral, Florida, where technicians moved it to nearby NASA Kennedy. Transported aboard the Canopée cargo ship, the European Service Module—assembled by Airbus with components from 10 European countries and the U.S.—provides propulsion, thermal control, electrical power, and water and oxygen for its crews.
“Seeing multi-mission hardware arrive at the same time demonstrates the progress we are making on our Artemis missions,” said Amit Kshatriya, deputy associate administrator, Moon to Mars Program, at NASA Headquarters in Washington. “We are going to the Moon together with our industry and international partners and we are manufacturing, assembling, building, and integrating elements for Artemis flights.”
NASA’s Pegasus barge, the agency’s waterway workhorse for transporting large hardware by sea, ferried multi-mission hardware for the agency’s SLS (Space Launch System) rocket, the Artemis II launch vehicle stage adapter, the “boat-tail” of the core stage for Artemis III, the core stage engine section for Artemis IV, along with ground support equipment needed to move and assemble the large components. The barge pulled into NASA Kennedy’s Launch Complex 39B Turn Basin Thursday.
The spacecraft factory inside NASA Kennedy’s Neil Armstrong Operations and Checkout Building is set to buzz with additional activity in the coming months. With the Artemis II Orion crew and service modules stacked together and undergoing testing, and engineers outfitting the Artemis III and IV crew modules, engineers soon will connect the newly arrived European Service Module to the crew module adapter, which houses electronic equipment for communications, power, and control, and includes an umbilical connector that bridges the electrical, data, and fluid systems between the crew and service modules.
The SLS rocket’s cone-shaped launch vehicle stage adapter connects the core stage to the upper stage and protects the rocket’s flight computers, avionics, and electrical devices in the upper stage system during launch and ascent. The adapter will be taken to Kennedy’s Vehicle Assembly Building in preparation for Artemis II rocket stacking operations.
The boat-tail, which will be used during the assembly of the SLS core stage for Artemis III, is a fairing-like structure that protects the bottom end of the core stage and RS-25 engines. This hardware, picked up at NASA’s Michoud Assembly Facility in New Orleans, will join the Artemis III core stage engine section housed in the spaceport’s Space Systems Processing Facility.
The Artemis IV SLS core stage engine section arrived from NASA Michoud and also will transfer to the center’s processing facility ahead of final assembly.
Under the Artemis campaign, NASA will land the first woman, first person of color, and its first international partner astronaut on the lunar surface, establishing long-term exploration for scientific discovery and preparing for human missions to Mars. The agency’s SLS rocket and Orion spacecraft, and supporting ground systems, along with the human landing system, next-generation spacesuits and rovers, and Gateway, serve as NASA’s foundation for deep space exploration.

4 Min Read Eclipses Create Atmospheric Gravity Waves, NASA Student Teams Confirm
In this photo taken from the International Space Station, the Moon passes in front of the Sun casting its shadow, or umbra, and darkening a portion of the Earth's surface above Texas during the annular solar eclipse Oct. 14, 2023. Credits: NASA Student teams from three U.S. universities became the first to measure what scientists have long predicted: eclipses can generate ripples in Earth’s atmosphere called atmospheric gravity waves. The waves’ telltale signature emerged in data captured during the North American annular solar eclipse on Oct. 14, 2023, as part of the Nationwide Eclipse Ballooning Project (NEBP) sponsored by NASA.
Through NEBP, high school and university student teams were stationed along the eclipse path through multiple U.S. states, where they released weather balloons carrying instrument packages designed to conduct engineering studies or atmospheric science. A cluster of science teams located in New Mexico collected the data definitively linking the eclipse to the formation of atmospheric gravity waves, a finding that could lead to improved weather forecasting.
“Climate models are complicated, and they make some assumptions about what atmospheric factors to take into account.”
Angela Des Jardins
Director of the Montana Space Grant Consortium, which led NEBP.
“Understanding how the atmosphere reacts in the special case of eclipses helps us better understand the atmosphere, which in turn helps us make more accurate weather predictions and, ultimately, better understand climate change.”
Catching Waves in New Mexico
Previous ballooning teams also had hunted atmospheric gravity waves during earlier eclipses, research that was supported by NASA and the National Science Foundation. In 2019, an NEBP team stationed in Chile collected promising data, but hourly balloon releases didn’t provide quite enough detail. Attempts to repeat the experiment in 2020 were foiled by COVID-19 travel restrictions in Argentina and a heavy rainstorm that impeded data collection in Chile.
Project leaders factored in these lessons learned when planning for 2023, scheduling balloon releases every 15 minutes and carefully weighing locations with the best potential for success.
“New Mexico looked especially promising,” said Jie Gong, a researcher in the NASA Climate and Radiation Lab at the agency’s Goddard Space Flight Center in Greenbelt, Maryland, and co-investigator of the research on atmospheric gravity waves. “The majority of atmospheric gravity sources are convection, weather systems, and mountains. We wanted to eliminate all those possible sources.”
The project created a New Mexico “supersite” in the town of Moriarty where four atmospheric science teams were clustered: two from Plymouth State University in Plymouth, New Hampshire, and one each from the State University of New York (SUNY) Albany and SUNY Oswego.
Students began launching balloons at 10 a.m. the day before the eclipse.
“They worked in shifts through the day and night, and then everyone was on site for the eclipse,” said Eric Kelsey, research associate professor at Plymouth State and the NEBP northeast regional lead.
“Our hard work really paid off. The students had a real sense of accomplishment.”

Each balloon released by the science teams carried a radiosonde, an instrument package that measured temperature, location, humidity, wind direction, and wind speed during every second of its climb through the atmosphere. Radiosondes transmitted this stream of raw data to the team on the ground. Students uploaded the data to a shared server, where Gong and two graduate students spent months processing and analyzing it.
Confirmation that the eclipse had generated atmospheric gravity waves in the skies above New Mexico came in spring 2024.
“We put all the data together according to time, and when we plotted that time series, I could already see the stripes in the signal,” Gong said. “I bombarded everybody’s email. We were quite excited.”

The program offered many students their first experience in collecting data. But the benefits go beyond technical and scientific skill.
“The students learned a ton through practicing launching weather balloons,” Kelsey said. “It was a huge learning curve. They had to work together to figure out all the logistics and troubleshoot. It’s good practice of teamwork skills.”
“All of this is technically complicated,” Des Jardins said. “While the focus now is on the science result, the most important part is that it was students who made this happen.”
