  "explanation": "There, just right of center, what is that? The surface of Mars keeps revealing new surprises with the recent discovery of finger-like rock spires. The small nearly-vertical rock outcrops were imaged last month by the robotic Curiosity rover on Mars. Although similar in size and shape to small snakes, the leading explanation for their origin is as conglomerations of small minerals left by water flowing through rock crevices. After these relatively dense minerals filled the crevices, they were left behind when the surrounding rock eroded away.  Famous rock outcrops on Earth with a similar origin are called hoodoos. NASA's Curiosity Rover continues to search for new signs of ancient water in Gale Crater on Mars, while also providing a geologic background important for future human exploration.

Deployment

Go-APOD can be self-hosted, either with Docker, via the 1-click Vercel or Heroku deployment, or by running the executable directly.
A NASA API Key is required, which you can sign up for at api.nasa.gov.

Vercel

Heroku

Docker

A multi-arch container is available on DockerHub, under lissy93/apod, or GHCR as ghcr.io/lissy93/go-apod.
Or, use this docker-compose.yml template, and just populate with your API key and run docker compose up.

docker run -p 8080:8080 -e NASA_API_KEY='XXX' -d lissy93/apod

From Executable

Each release has pre-compiled binaries attached for Windows, Mac and Linux, which can be run directly. From the Releases Page, download and extract the version for your system, then execute it with: NASA_API_KEY='XXX' ./go-apod
