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.”

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.

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 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.”

Sols 4232-4233: Going For a Ride, Anyone?
This image shows some of the sand ripples we spot all around the rover between the rocks. It was taken by Mast Camera (Mastcam) onboard NASA’s Mars rover Curiosity on Sol 4225 (2024-06-25 01:10:39 UTC). Earth planning date: Monday, July 1, 2024
Have you ever wondered what it might look like to ride along with the rover? Probably not as much as we have here on the planning team, where we are looking at the images on a daily basis. I always wish I could walk around there myself, or drive around in a vehicle, maybe. As you likely know, we don’t even get video, “just” images. But of course those images are stunning and the landscape is unique and – apart from being scientifically interesting – so very, very beautiful. And some cameras record images so often that it’s actually possible to create the impression of a movie. The front hazard camera is among them. And that can create a stunning impression of looking out of the front window! If you want to see that for yourself, you can! If you go to the NASA interactive tool called “Eyes on the Solar System” there is a Curiosity Rover feature that allows you to do just that: simulate a drive between waypoints and look out of the window, which is the front hazard camera. Here is the link to “Experience Curiosity.” The drive there is a while back, but the landscape is just so fascinating, I can watch and rewatch that any number of times!
Now, after reminiscing about the past, what did we do today? First of all: change all plans we ever had. We don’t have – as scheduled – the SAM data on Earth just yet. But we have a good portion of the sample still in the drill, and if SAM gets their data and wants to do more analysis with that sample, then we can’t move the arm as we originally had planned. Why didn’t we consider that to begin with? Normally, there isn’t enough sample for all the analysis; you may have seen this blog post: “Sols 4118-4119: Can I Have a Second Serving, Please? Oh, Me Too!” But it’s the sample that dictates how much we get to begin with, and how much we need, which only becomes clear as the data come in. And there is an unusually lucky combination here that would avoid us having to drill a second hole for getting the second helping. Instead, we just sit here carefully holding the arm still so we do not lose sample. That saves a lot of rover resources. But then, once we had settled how we adjust to keeping our current position, we also learnt that the uplink time might shift from the original slot we had been allocated to a later one… And all of this with a pretty new-to-the-role Science Operations Working Group (SOWG) chair (me) and a similarly new Geology and Mineralogy theme group science lead. Well, we managed, with lots of help from the great team around us.
Those sudden-change planning days are so tricky because there is so much more to remember. It’s not, “This is what we came to do…,” and it had been carefully pre-planned, and it is all in the notes. Instead, the pre-planning preparation doesn’t fit the new reality anymore, and all that work has to be redone. So we have to do all the pre-planning work, and the actual planning work, and sometimes also account for some “if… then…” scenarios in the same amount of time we usually have to do the planning on the basis of all the pre-planning work.
Sounds stressful? Yes, I can tell you it is!
Once we had changed all the skeleton plans, the team got very excited about the extra time. This is such an interesting area, there are rocks that are almost white, there are darker rocks, very interesting sand features with beautiful ripples, so much to look at! Mars has much to offer here, so the team got to work swiftly and the plan filled up with a great set of observations. ChemCam used LIBS on the target “Tower Peak,” which is one of those white-ish rocks, and on “Quarry Peak.” Mastcam delivers all the pictures to go along with these two activities and gets its own science, too. These are mainly so-called “change detection” images, where the same area is pictured repeatedly to see what particles might move in the time between the two images. ChemCam uses its long-distance imaging capability to add to the stunning images they are getting from faraway rocks. They have two mosaics on a target called “Edge Bench.” There is also a lot of atmospheric science in the plan; looking for dust devils and the opacity of the atmosphere are just two examples. REMS and DAN are also active throughout, to assess the wind, and the water underground, respectively. And as if that weren’t enough, CheMin also performs another night of analysis. We get to uplink a full plan, and we’ll see what the data say and what decisions we’ll make for next Wednesday.

2 Min Read Going the Extra 500 miles for Alaskan River Ice
Fresh Eyes on Ice science team from the University of Alaska Fairbanks stop in the Alaska Native village of Shageluk on a community and citizen science journey of 550 mile by snow mobile. Credits:
Photo by Amanda Byrd, UAF Teachers and students in remote Alaskan villages have become vital NASA climate researchers. These special volunteers are so important that last year, climate scientists took an epic 550 mile snowmobile journey to collaborate with them! You can learn all about it in a new video from the Fresh Eyes on Ice project.
The researchers stopped at several remote Alaskan villages, where teachers and students at the local schools already understood why this work was so crucial. When you drive over ice-covered rivers every day—as many Alaskan residents do—tracking ice thickness is no joke. Neither is climate change.
“We knew that climate change was happening around us.” explains Joyanne Hamilton, a teacher whose students worked with the team. “Our elders here in Shageluk were talking about changes that were happening….the data they’re gathering is ultimately important to the tribe.”
The new video features Hamilton, her students, and Fresh Eyes on Ice researchers Dr. Chris Arp, Allen Bondurant and Sarah Clement. It follows their journey along the Innoko, Kukokwim and Yukon Rivers and the Iditarod Sled Dog Trail.

NASA / Scott Battaion NASA’s Wallops Flight Facility C-130 aircraft, shown in this image from Oct. 28, 2023, delivered the agency’s Galactic/Extragalactic ULDB Spectroscopic Terahertz Observatory (GUSTO) payload to McMurdo Station, Antarctica. This was the first mission to Antarctica for the plane.
The GUSTO mission, launching aboard a football-stadium-sized, zero-pressure scientific balloon in December 2023, will fly an Ultralong-Duration Balloon (ULDB) carrying a telescope with carbon, oxygen, and nitrogen emission line detectors. This unique combination of data will supply the spectral and spatial resolution information needed for the mission team to untangle the complexities of the cosmic material found between stars, and map out large sections of the plane of our Milky Way galaxy and the nearby galaxy known as the Large Magellanic Cloud.
