👋 We’re SCoPE—the STEM Community of Practice for Education.

We support scientists and research teams with science engagement & outreach training that helps them share their work clearly, purposefully, and effectively.

Our goal is to strengthen the bridge between science and the public.

If you’d like to learn more about heat shields, including the Artemis I and Artemis II heat shields developed at NASA Ames Research Center in Silicon Valley, this is a good place to start:

You don't have to tell that to someone who enjoys making science 🧪 memes as a side hobby. 🤷‍♂️ #ScienceSky

Thermal infrared image of Earth. Cold high clouds are white, warm ocean is dark gray or black. In some areas it is hard to distinguish clouds from land or water because the temperature is similar. Rotated 145˚ counter-clockwise, so north is to the lower-left.

Long exposure view of Earth at Night. Blue ocean, brown desert, and green forest are all visible I between vast expanses of blue water and swirling white clouds.

I was curious what a view of Earth matching the Artemis II pic would look like from a conventional weather satellite.

Here’s a thermal infrared (heat) image from directly above the Prime Meridian at 00:30 April 3rd from @eumetsat.int (MTI1) rotated to match as closely as possible.

#GISchat: GIS for Good: Esri’s Commitment to People, Planet, Prosperity, and Peace

I was going to listen to the Nature Careers podcast episode ⬇️, but then I decided I would check it out later because I had other things I want to do first. 🤷‍♂️ What's that called again? 😆

#EOchat: One of the things I'll always be fascinated by w/ #EarthEngine is the ability to rapidly pull wall-to-wall imagery from sources like #Landsat and use simple #ML to extract features like #LandCover. Kudos to the GEE team, b/c "no pixels were downloaded in the processing of this data." 😉

Ridgeplot showing March daily high for downtown San Francisco from 1921 to 2026. (Data past March 19, 2026, are from the NWS forecast.) It’s hot this spring, but it was 1 degree hotter — 86˚F — in 2005.

After mapping the heatwave I’m currently living through, I thought it might be interesting to take a look at some non-spatial ways of showing how unusual this is. So I dove into the data for downtown San Francisco, which goes back more than 100 years, to 1921. First up: a ridgeplot.

Oh no! Jeff was a regular at NACIS conferences and I enjoyed our conversations. Very sad indeed. Sending my very best wishes to his family, friends and the many students he has taught.

Jeff taught one of the colleagues I hired at Planet. He was an excellent teacher, and will be missed.

In Memoriam: Jeff Howarth The geography professor known for his excellence in teaching and commitment to research died following a battle with cancer.

Prof. Howarth was one of the co-authors of the #EarthEngine #EEFA book. Condolences to his family and his friends. May he rest in peace.

Screenshot of Friday's hourly weather with the hottest part of the day circled (i.e., the best time to be in our sessions).

Hey #AAG2026, tomorrow afternoon's going to be pretty warm so come cool off at our urban green space sessions!

Co-organized by the wonderful @jkhawes.bsky.social & @urbanparksgirl.bsky.social. Come for the great research, stay for the post session social 🍻

I can’t believe we’re at the stage of a techbro CEO declaring loudly that they want to replace innate human intelligence with a product that they’ll sell, and everyone is like “yeah, but look at how quickly I can make a graph now!”

NISAR Science Team Meeting - Town Hall and Data Access Webinar (Feb 2026) YouTube video by NASA Video

#EOchat: I'm hoping that folks have been able to look at #NISAR 🛰️ data for their own AOIs. That said, if you missed it and are looking for a summary of what the NISAR mission is up to, the mission team has shared the video of the recent (27.02.2026) Town Hall: www.youtube.com/watch?v=7tJJ....

New Landsat Science Team Announced The U.S. Geological Survey, in cooperation with NASA, has named the new Landsat Science Team that will support the world’s longest-running Earth observation mission for a planned 2026-2030 term.

Rounding out 2025 with exciting news… I’m honoured to join the 2026–2030 Landsat Science Team! A full-circle moment for me after starting my career using Landsat for fire monitoring. #EOChat #GISChat

#EOchat: Following last week's initial release of #NISAR L-band #SAR 🛰️ data by the #ASFDAAC, here's some sample data over northeastern #Guatemala. The large red splotches in the 1st 2 images (freq. A) are RFI artefacts, not visible in the 2nd 2 images (freq. B). #GoldenAgeOfSAR

Good to know! I also remember that the ASTER GDEM was challenging.

Thanks, Dr. Simmon! From your perspective, how would you say it compares to the Copernicus DEM? 🤔

Shuttle Radar Topography Mission (SRTM) | NASA Earthdata Used to gather topographic (elevation) data of Earth's surface, NASA's SRTM used interferometry.

#GISchat: #OTD in 2000, NASA's Shuttle Radar Topography Mission (SRTM) wrapped up its mapping of much of Earth's surface. For many years (probably until Copernicus DEM was released a few yrs ago), SRTM's output was considered *the* best quality global DEM. 🧐 www.earthdata.nasa.gov/data/instrum...
