Retrieve data from NASA\
The NASA node pulls data from NASA's public APIs: astronomy pictures, asteroid feeds, space weather events and satellite imagery, optionally downloading images as binary. A typical build is posting the astronomy picture of the day to a channel each morning with its explanation.

NASA
Retrieve astronomy images, asteroid data, space weather, and satellite imagery from NASA APIs
Overview
The NASA tool provides access to multiple NASA open APIs: Astronomy Picture of the Day (APOD) with optional image download, Near-Earth Object (NEO) asteroid tracking via feed/lookup/browse endpoints, nine DONKI space weather event types (CME, HSS, IPS, MPC, notifications, RBE, SEP, solar flare, WSA+Enlil), Earth Assets metadata, and Earth Imagery satellite image download. Binary data is produced for APOD image downloads and Earth Imagery. All endpoints are read-only GET requests authenticated via api_key query parameter.

Output Data
Every resource merges its result onto the input item JSON — the incoming fields pass through unchanged. One output item per input item: no resource fans out, so lists arrive as arrays on a single item. Binary from the input item is forwarded, and the two image resources add a new binary property alongside it.
| Resource | Fields merged onto the item |
|---|---|
astronomyPictureOfTheDay | The whole APOD response (title, explanation, media_type, url, hdurl, date, and so on). With Download Image on and media_type equal to image, the picture is also written to the named Binary Property, keeping the file name from the source URL. |
asteroidNeoFeed | asteroids (array of near-Earth objects) and element_count. |
asteroidNeoLookup | The whole asteroid record. close_approach_data is stripped out unless Include Close Approach Data is on. |
asteroidNeoBrowse | asteroids (array) and totalCount. |
donki* (all nine) | events (array of the event records the API returned) and eventCount. |
earthAssets | The whole Earth Assets response for that coordinate. |
earthImagery | lat, lon, date, dim and fileSize. The satellite image itself is written to the named Binary Property as earth_imagery_{lat}_{lon}_{date}.png. |
Because lists come back as arrays on one item, use a Split Out node on asteroids or events when you want one item per record. Reference the result downstream by expression, e.g. {{ $json.eventCount }} or {{ $json.asteroids }}.

Behavior notes
- Dates default sensibly. APOD, Earth Imagery and the asteroid feed default to today; DONKI resources default to the last 30 days. Any date you supply is normalised to
YYYY-MM-DD, so an ISO timestamp or a date picked up from an upstream item works too. - Asteroid Neo-Feed returns one day’s objects. Even with a multi-day range,
asteroidscarries the objects for the first date in the response — narrow the range to the day you care about rather than expecting the whole window in one array. - Return All really means all. On Asteroid Neo-Browse it pages through the entire dataset 20 records at a time and does not stop until NASA runs out of pages. Leave it off and set a Limit unless you genuinely want everything.
- APOD is not always a picture. Some days are videos; the download is skipped when
media_typeis notimage, and the item still carries the APOD metadata. - Latitude and Longitude are mandatory for the Earth resources even though the editor does not mark them required — an item without both fails.
Common patterns
- Daily astronomy content — use
astronomyPictureOfTheDaywith an optional date and the image download for editorial or educational workflows. - Space weather monitoring — use the DONKI resources with a date range to track events that could affect satellites or ground systems.
- Asteroid tracking — combine
asteroidNeoFeedfor recent activity withasteroidNeoLookupfor the detail on a specific object. - Earth observation — pair
earthAssets(what imagery exists) withearthImagery(fetch the picture) for the same coordinates.
Frequently asked questions
Do I have to supply dates?
No — they default sensibly. APOD, Earth Imagery and the asteroid feed default to today, and DONKI resources default to the last 30 days. Any date you supply is normalised to `YYYY-MM-DD`, so an ISO timestamp from an upstream item works too.
Why does the asteroid feed only cover one day?
Asteroid Neo-Feed returns one day's objects even with a multi-day range specified, so loop over dates if you need a longer window.
Can it download the images themselves?
Yes — optional binary image download brings the picture through as binary data ready to post or store, rather than just a URL.
Which credential does it need?
A NASA API credential. NASA offers a demo key, but a registered key has far higher rate limits.
Build with the NASA node
Drop it into a workflow, wire it to an agent, or call it on a schedule. You'll need NASA API credentials first.
