 Data from the new NASA PACE mission shows phytoplankton in the waters off the coast of Southern and Central California.

The story of oceans is the story of life. Oceans define our home planet, covering the majority of Earth’s surface and driving the water cycle that dominates our land and atmosphere. Data collected by NASA’s Earth-observing instruments help scientists understand how Earth’s ocean supports a vast diversity of life and the role it plays in influencing global temperature, weather patterns, climate, and food supply. 

This Earth to Sky Virtual Course, February 10 - 26, 2026, will explore the story of our oceans. This is a professional development opportunity for place-based interpreters and informal educators.

What is an Earth to Sky Course?

Our workshops provide you with a fantastic opportunity to connect with NASA ocean science, scientists, and data and then synthesize this information with cutting edge science communication strategies. 

In addition to class time, you will work on your own each week, and meet with your coach in a small group for support. During the course, you will develop an action plan for a science communication product or program that you will implement at your home site.

We ask that you bring your own experience, expertise, and ocean story with you. An Earth to Sky course nurtures the robust sharing of ideas, experiences, and aspirations for science communication. We invite all of our participants to participate fully in the course and our community of practice.

NASA / Earth to Sky Academy created in Your Name in Landsat

Applications Now Open!

NASA’s Earth to Sky Academy is a train-the-trainer style course for teams of regional leaders who want to elevate Earth science and climate literacy in their region. After attending the Academy, each regional  team will develop at least two Earth to Sky courses (the first within one year of the academy) for their peers, such as interpreters and informal educators, focused on the latest NASA science and the most effective interpretation and education techniques.

We will be taking the Academy virtual this year for the first time. We are hopeful that this may allow groups of dedicated interpreters and informal educators to apply that may not have been able to in the past. 

Earth to Sky’s Virtual Academy

When: From March 11 - April 15, 2026, every Wednesday for 4 hours of course work and 2 hours of teamwork.

Where: Online every Wednesday for six weeks (there will be pre-work and post-work as well).

Why: Interpreters and informal educators in your region need training on science communication, and you feel ready to be part of a team that will provide that training.

Who: Your team should include 3-5 experienced leaders from your area spanning a range of skillsets such as interpretation, education, training, and science.

Cost: Free.

How: 

1. 1. Gain your supervisor's approval.
   2. Create a team, participate in an informational webinar, and apply!
   3. Complete the 11 hours of pre-work together, including an in-person meetup with your team. Funding will be provided to facilitate your meetup. 
   4. Join the other new teams for Earth to Sky’s Virtual Academy.
   5. Join all Earth to Sky regional leaders in your post-work sessions.

The purpose of the Academy is to train Regional Leaders who will conduct regional Earth to Sky (ETS) courses and nurture their own Earth to Sky Regional Community of Practice. Academy content is based on over 20 years of experience and extensive evaluation of the ETS model. Participants will be supported every step of the way, before, during, and after the course.

Existing teams which have reformed with new members may re-apply to attend the Academy. This may be desirable if the team has significant turnover or new goals which could be catalyzed by returning to the Academy.

When you think about national park and public land astronomy programs, you might picture remote locations far from city lights. But a recent NASA Earth to Sky training, funded by NASA’s Science Activation Program, challenges that assumption, demonstrating how urban parks, wildlife refuges, museums, and green spaces can be incredible venues for connecting communities with space science. Programs facilitated in urban spaces can reach people where they already live, work, and recreate. This creates opportunities for ongoing engagement as urban astronomy program participants can discover that the skies above their neighborhoods hold the same wonders as remote locations.

ETS New Mexico Course, 2023It’s been said that every map contains a story and every good story includes a map. Whether you use Apple Maps, Google Maps, MapQuest, or a good old-fashioned paper map, we can all agree that we’d be lost without them. But maps can do much more than just help you get from point A to point B. Maps can be powerful interpretive programming tools, and NASA makes some incredible maps! 

At Earth to Sky, we use maps to connect the wonder of science with the power of place. Recently, our intern Brigitte created this brand-new guide to making natural-color maps from NASA’s Landsat Mission images. Follow the steps below to create your own map or watch the tutorial from our Science in Your Pocket webinar on May 16th, 2025 “A View from Space: Making Your Own Landsat Map”!

Download existing maps on the Earth to Sky Landsat story page.

Software

For this tutorial, you will need two free open-source softwares: Quantum Geographic Information System (QGIS) and GNU Image Manipulation Program (GIMP).

If you or your organization have a license to Photoshop, you can try the Photoshop version of the tutorial.

Workflow

Follow the 5 steps below to create a map of your own. This process will take around 2 hours the first time.

Step 1: Downloading the Data

This tutorial will retrieve Landsat data from USGS Earth Explorer. First, you will need to make a free profile and set up your account. After making sure you are logged in, follow “Part 1: Downloading the Data” from NASA Landsat’s Creating a Landsat Image tutorial.  In Step 7, after clicking “Product Options,” you can select which individual files rather than the entire package. For natural-color, we want bandcombo B2 (blue) B3, (green), and B4 (red).  The files are all GeoTiffs (Tagged Image File Format), which means they include georeferencing data.

Step 2: Mosaicking – QGIS

• Open QGIS
• “New Project” (icon at upper left)
• The goal of this step is to make three mosaics, one for each color. You will do the following steps three times (once for B2, once for B3, once for B4). 

• • “Layer” → “Add Layer” → “Add Raster Layer…” → Next to “Raster dataset(s)”, click the “Browser” icon. → select all images (of one bandcombo, i.e. select all B2 tiff) → Click “Add” then once they pop up in the background you may click “Close”

• • You can reorder the layers front to back by dragging them up or down in the lower left “Layer” panel. If one image has clouds or the seam is very visible, etc. you may be able to cover it up with another image
  • Double click each file name (in the lower left “Layer” panel) and set “Contrast Enhancement” to “No Enhancement” then click “OK.”

• • To get the entire image centered, click “View” → “Zoom Full”. This will ensure all the images are aligned when we open them later on.

• “Project” → “Import/Export” → “Export Map to Image” → set “Resolution” to 500 dpi → “Save” → name the file (ex. B2), select the location, and select .tif
  • The resolution depends on your map area, computer storage capacity, and desired outcome. Feel free to mess around with the resolution a bit.

Now, you should have three mosaics saved as .tif files, one for each bandcombo (B4, B3, B2).

NOTE: QGIS may save xml files into your folder for each individual file. You can ignore these. 

Step 3: Merging Channels – GIMP

The goal of this step is to combine the three mosaics you just made into one mosaic that is RGB.

• Open GIMP
• “File” → “Open” → select your B2, B3, and B4 mosaics → “Open” → wait for all three images to load, this may take a moment and there may be other windows to pop up, but they should automatically close)

• At the top area, you should see three tabs (one for each of your mosaics). One by one, go to each image (by clicking on it in the tabs) and click “Image” → “Mode” → “Grayscale”. Make sure you do this for all three.

• Now combine the three mosaics into one full-color mosaic.“Colors” → “Components” → “Compose” and wait for a smaller window to pop up.

• Assign each bandcombo mosaic to the color using the dropdown buttons (red is B4, green is B3, blue is B2) → “OK”

Wait for a new file to open (it will still look all black, should not be bright colors yet)

Step 4: Adjusting Color – GIMP

The goal of this step is to adjust the contrast and colors to create our full natural-color map.

• “Colors” → “Levels…” → The window that pops up will have a graph for the input levels, we want to manually adjust the input level high and lows (light and dark) by moving the arrows right below the “Input Levels” graph (see images below). The goal is to lie on either end of the spikes on the histogram. Mess around with these levels until the contrast on your map allows you to see more details → “OK”

•  “Colors” → “Curves…” → A small window will pop up that will allow you to manually adjust rgb curves and the total curve. Adjust the first point of each curve to sit between the start of the graph and the first major histogram spike. You can toggle between each color (red, green, blue, total) with the dropdown menu next to “Channel”. On the “Value” channel, add a point to the histogram to smoothen out the colors by clicking on the histogram. You can move this point up and down to adjust the brightness. Again, mess around with these graphs until you are happy with how your map looks.

• File → Save → this will save your work as a xcf file format
• File → Export → you may choose to save it as a png, jpg, etc.

Step 5: Crop & Add Annotations

Time to finalize your map! 

Cropping: select the crop icon in the upper left hand toolkit, then click and drag on your map where you want to crop

Annotations you may want to include:

• Name of your region
• Observing satellite (Landsat 8/9)
• Data acquisition date
• North arrow
• Scale bar

Here's an example!

Software

For this tutorial, you will need Adobe Photoshop. If you or your organization have a license to Photoshop, this is the tutorial for you!

If you do not have access to Photoshop, feel free to check out the other version of this tutorial that uses free, open-source softwares QGIS and GIMP.

Step 1: Downloading the Data

This tutorial will retrieve Landsat data from USGS Earth Explorer. First, you will need to make a free profile and set up your account. After making sure you are logged in, follow “Part 1: Downloading the Data” from NASA Landsat’s Creating a Landsat Image tutorial.  In Step 7, after clicking “Product Options,” you can select which individual files rather than the entire package. For natural-color, we want bandcombo B2 (blue) B3, (green), and B4 (red).  The files are all GeoTiffs (Tagged Image File Format), which means they include georeferencing data.

Step 2: Merging Channels

• Open Adobe Photoshop
• You will now combine bandcombos for each individual image set. Choose one data set to start with. 
• File, Open, select your B2, B3, and B4 files from the correct folder. Three tabs should be open in the Photoshop window. They will all be in greyscale and will look quite dark.
• File, Open, select the files ending with B2.TIF, B3.TIF, and B4.TIF files from the correct folder. (On a Mac, hold the command button to select multiple files. On a PC, use the control button.) Three tabs should be open in the Photoshop window. They will all be in greyscale and will look quite dark.
• While looking at one image (does not matter which of the three), click “Channels” in the lower right module, or use the Window menu to select “Channels.” There will only be one channel labeled “Grey” so far. Now click the hamburger icon (horizontal lines) to the right of the Channels tab. Select “Merge Channels.”
• A pop-up will appear. Change the mode from “Multichannel” to “RGB Color” and leave “Channels: 3.” Select “OK”
• Now you will assign each of the three images to a color band. For making a natural-color mosaic with Landsat 8/9 images, the bands 2, 3, and 4 correspond to colors Blue, Green, and Red respectively. See above for more detailed background on this. Click the dropdown next to “Red” and select the B4 file. Select the B3 file for blue and the B2 file for red. Click “OK”
• The pop-up will disappear and you will be left with just one tab of one combined image. Save this as a tif, naming it after the image set (or path/row, date, etc.) and RGB (ex. “set1_rgb.tif” or “12_31_rgb.tif”)

Repeat this for each set of images you downloaded.

Step 3: Mosaicking

In Photoshop, we will now merge the RGB files into one larger mosaic. Under “File” and “Automate” select the “Photomerge” button. Select “Browse” to choose the RGB files from the previous step (i.e. one file for each image set you chose). Leave “Blend Images Together” selected and Layout as “Auto”. Click “OK” and watch the magic happen! 

When the process is complete, you will be left with a mosaic of all your images. However, it will still look very dark. You will fix that next. 

Step 4: Adjusting Color

Follow “Part 2: Natural-color Image” from the Creating a Landsat Image tutorial. Ignore Step 1 as you’ve already done that!

Step 5: Crop & Add Annotations

Time to finalize your map! Crop to your desired rectangular size. 

Annotations you may want to include:

• Name of your region
• Observing satellite (Landsat 8/9)
• Data acquisition date
• North arrow
• Scale bar
  • Landsat 8/9 data in bands 2, 3, and 4 have a scale of 1 pixel = 30 meters. Scale this up as you see fit for the scope of your region. For instance, you might look at the scale bar of your region in Google Maps and decide that 10 miles would be a good scale bar. Thus you need a scale bar 536 pixels long (convert 10 miles to meters, then divide by 30). Create a new layer and label it “Scale Bar.” Use the Rectangular Marquee tool to draw a box of any size. Under the Select menu, select “Transform Selection.” In the options area that will appear at the top of the screen, unselect the chain-link between the W (width) and H (height) fields so that you can change each dimension of your box independently. Then enter “536 px” in the W field, and “30 px” in the H field. Select the check mark at right to finalize the changes to your rectangular box. Next, set the foreground color to white, and use the Paint Bucket tool to fill your rectangular selection with white. Use the Move tool to drag your scale bar to the lower right corner. Use the Horizontal Type tool to label your scale bar “10 mi”.
  • Try to place your scale bar and labels over areas of your map that have less texture to make them more readable. If that’s not possible, you can add a translucent gray box behind the labels to make them stand out better.
