Interesting Rock Textures Galore at Bright Angel

Rocky, pale-orange-colored terrain on Mars. What looks like fine-gran sand is interspersed with many jagged rocks pointing out of the ground; a few of the rocks are gray, not orange.
NASA’s Mars Perseverance rover acquired this image using its Right Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover’s mast. This image was acquired on June 10, 2024 (Sol 1175, or Martian day 1,175 of the Mars 2020 mission) at the local mean solar time of 14:04:57.

Upon the rover’s arrival at Bright Angel, it was so exciting to see all the interesting features in the rocks of this interval! In particular, these rocks contain an abundance of veins and nodules. Veins are linear features containing mineral crystals that often form thin plates or sheets that cut through the rocks and across other veins. Veins are often more resistant to erosion than the rocks they are found in so they stand out in raised relief. Nodules are small, rounded protrusions in the rocks. Nodules are often sites of mineral formation distinct from the surrounding rock.

Veins and nodules form when water flows through a rock, and minerals crystallize from this water in cracks and empty spaces within the rock. Features like this were previously observed by Perseverance during its exploration of the sedimentary rocks of the western fan, particularly during the “Fan Front Campaign” at Hogwallow Flats. However, these features have been sparse in the margin unit. The omnipresence of veins and nodules in the rocks of Bright Angel is truly striking. We hope to get more data on these interesting features over the next few weeks because they may signify intense water-rock interaction at this site!

Station Nation: Meet Katie Burlingame, ETHOS Flight Controller and Instructor in the Flight Operations Directorate

Station Nation: Meet Katie Burlingame, ETHOS Flight Controller and Instructor in the Flight Operations Directorate

Katie Burlingame is an ETHOS (Environmental and Thermal Operating Systems) flight controller and instructor in the Flight Operations Directorate supporting the International Space Station. Burlingame trains astronauts and flight controllers on the International Space Station’s environmental control systems, internal thermal control systems, and emergency response. Burlingame shares about their path to NASA, what Pride Month means to them, and more. Read on to learn more!

Where are you from?

My dad was in the Coast Guard, so I lived in a few different places growing up, mostly along the East Coast and Southeast. I lived near Orlando, Florida in high school, so that’s usually what I’ll go with for a short answer.

Tell us about your role at NASA.

I execute and plan operations in the Mission Control Center. I train flight controllers and astronauts, specifically for the International Space Station’s environmental control systems, internal thermal control systems, and emergency response.

Katie Burlingame demonstrates how to use new emergency response hardware during Starliner-1 crew training.

How would you describe your job to family or friends who may not be familiar with NASA?

For anyone who has seen Apollo 13, I usually say I’m one of the people who figures out what to do in response to “Houston, we have a problem.” Environmental control systems are basically what makes sure there is clean air to breathe and water to drink. Internal thermal control systems are the water lines running throughout the space station that keeps all the computers and other hardware cool.

As far as training goes, the biggest part is training on emergency response, so what to do if there is a fire on the space station or if you start losing air overboard due to a hole in the structure. We have life-size replicas of the space station and simulators that can replicate all its data. This allows us to create opportunities for crew and new flight controllers to practice responding in the situations they could experience aboard the station – sometimes I even get to use a smoke machine!

How long have you been working for NASA?

I have been with the agency for 11 years.

What advice would you give to young individuals aspiring to work in the space industry or at NASA?

Follow the things that you find most interesting. We need people with all kinds of skills in the space industry, so don’t feel like you have to stick to the most traditional path.

What was your path to NASA?

In college, I worked in a lab that built small satellites, which led me to opportunities to participate in the reduced gravity aircraft program and internships at NASA’s Johnson Space Center in Houston. I got a master’s degree in biomedical engineering and was originally planning to work on medical devices after college. While at my first job, the industry I was in was experiencing a wave of layoffs, so when I heard about an opportunity back at Johnson, I decided to apply and have been here ever since.

Is there someone in the space, aerospace, or science industry that has motivated or inspired you to work for the space program? Or someone you discovered while working for NASA who inspires you?

I’m inspired by the teammates I get to work with every day. Seeing the different skills that people bring to the table, how they handle difficult situations, and come up with creative solutions impresses me and motivates me to keep growing and learning.

What does diversity, equity, and inclusion mean to you? How does it guide you in your work at NASA?

To me, diversity has a lot of aspects because it encompasses all of the things that contribute to someone’s unique experience and perspective. Spaceflight is hard, and solving tough problems requires creative and integrated solutions, which requires teams with a diversity of thought, skills, perspectives, and experiences.

It means ensuring that NASA is comprised of a workforce that reflects the full spectrum of the country we represent, and then making sure that everyone has the resources they need to thrive and are part of a community that welcomes and respects their full selves. I try to keep this as a guiding priority throughout my work, in day-to-day things like the language and assumptions I make when talking with people and in looking for and advocating for larger systemic ways to make improvements. Having a diverse, equitable, and inclusive workplace is the just and fair thing to do, but it also helps us do the best work to accomplish NASA’s missions.

What is your favorite NASA memory?

I had the opportunity to work on several aspects of the first U.S. crewed vehicle missions. Working with NASA, commercial partners, and the international partner teams to figure out how to best execute training and emergency response was an interesting technical problem and it is great to see all of the things we worked on being used regularly now.

What do you love sharing about station? What’s important to get across to general audiences to help them understand the benefits to life on Earth?

There have been people continuously on the International Space Station for more than 23 years! That’s amazing as a technical achievement, but also an example of successful and sustained international partnership.

What does Pride Month mean to you?

Pride Month is a celebration of the LGBTQIA+ community and the progress that has been made. It’s also a call to action for allies and community members to protect and support LGBTQIA+ community members and their rights, especially the most marginalized.

What does it mean to embrace LGBTQIA+ pride?

To me, embracing pride is embracing the understanding that we are each worthy of honor and respect as we are and creating an environment where others can do the same.

Who are some of your LGBTQIA+ role models?

My role models are all of the advocates for LGBTQIA+ rights, past and present, and everyone who shows up in small and big ways as themselves.

What are your hobbies/things you enjoy outside of work?

I like going to see plays and musicals and exploring Houston’s restaurants, coffee shops, and bookstores. When the Houston heat isn’t too bad, I like exploring parks, riding my bike, and doing triathlons (very slowly).

Day launch or night launch?

Night launch!

Favorite space movie?

I don’t have a strong favorite space movie, but my current favorite space books are “Project Hail Mary” by Andy Weir and “The Long Way to a Small, Angry Planet” by Becky Chambers.

NASA “worm” or “meatball” logo?

Meatball.

A new custom virtual reality flight simulator built by NASA researchers will allow them to explore how passengers experience air taxi rides and collect data that will help designers create new aircraft with passenger comfort in mind.

Wayne Ringelberg, a test pilot at NASA’s Armstrong Flight Research Center in Edwards, California, recently completed a series of test rides in the new simulator to help the team make adjustments before other users are involved for the first research study later this year.

“This project is leveraging our research and test pilot aircrew with vertical lift experience to validate the safety and accuracy of the lab in preparation for test subject evaluations,” said Ringelberg. “The experiments in the ride quality lab will inform the advanced air mobility community about the acceptability of the motions these aircraft could make, so the general public is more likely to adopt the new technology.”

Ringelberg was secured into the seat on top of the simulator’s platform, wearing a virtual reality headset and headphones. His simulated air taxi ride started with a takeoff from a conceptual vertiport on top of a parking garage in downtown San Francisco, California, constructed by NASA engineers in the virtual world.

As the programed ride took him through downtown San Francisco and landed at another vertiport on top of a skyscraper, Ringelberg evaluated the realism and consistency of the simulation’s visual, motion, and audio cues. He then provided feedback to the research team.

With pilot checkouts complete, NASA researchers will conduct a series of human subject research studies over the next four years. The goal is to gather information that will help the industry better understand what makes flying in an air taxi comfortable and enjoyable for customers.

This simulator is the centerpiece of NASA Armstrong’s virtual reality passenger ride quality laboratory. The laboratory combines virtual reality visuals, physical motion cues, and spatialized rotor sounds to create an immersive air taxi passenger experience.

The work is managed by the Revolutionary Vertical Lift Technology project under NASA’s Advanced Air Vehicles Program in support of NASA’s Advanced Air Mobility mission, which seeks to deliver data to guide the industry’s development of electric air taxis and drones.
