This is a Golang client for the NASA NeoWs API. The API is maintained by the SpaceRocks team (David Greenfield, Arezu Sarvestani, Jason English and Peter Baunach).
I am not affiliated with the aforementioned groups and this is not an official initiative from them. This is also a work in progress (WIP) and it is not production-ready.
go get https://github.com/viniciusrtf/nasa-neows-goSetup your client
client := neows.NewClient("your-api-key")Optionally, enable caching NeoWs API responses
client.EnableCache()Lookup an asteroid by its SPKID or Asteroid Name
neo, err := client.Lookup.Find("2023 BU")Get approaching asteroids for the next 7 days
feed, err := client.Feed.Fetch(time.Now(), time.Now().AddDate(0, 0, 7))Get today's approaching asteroids
feed, err := client.Feed.Today()Get detailed information about approaching asteroids from "2021-06-01" to "2021-06-02" (YYYY-mm-dd)
start, err := time.Parse("2006-01-02", "2021-06-01")
if err != nil {
t.Errorf("Error parsing start date: %s", err)
}
end, err := time.Parse("2006-01-02", "2021-06-02")
if err != nil {
t.Errorf("Error parsing end date: %s", err)
}
fs := NewFeedService(client, &FeedOptions{Detailed: true})
feed, err := fs.Fetch(start, end)A more complete example: Get approaching asteroids for a given date range:
package main
import (
"fmt"
"github.com/viniciusrtf/nasa-neows-go"
)
func main() {
// See https://api.nasa.gov/#signUp to generate an API Key
apiKey := "your-api-key"
client := neows.NewClient(&apiKey)
client.EnableCache() // optional
// Get a feed with close approaches by date range
start, err := time.Parse("2006-01-02", "2021-06-01")
if err != nil {
t.Errorf("Error parsing start date: %s", err)
}
end, err := time.Parse("2006-01-02", "2021-06-02")
if err != nil {
t.Errorf("Error parsing end date: %s", err)
}
feed, err := client.Feed.Fetch()
if err != nil {
panic(err)
}
if feed.ElementCount == 0 {
fmt.Println("No close approaches for the given date range")
}
// Print asteroids info by date
for date, neo := range feed.NeosByDate {
fmt.Printf("Asteroids approaching in %s\n", date)
for _, n := range neo {
fmt.Printf("\tName: %s\n", n.Name)
fmt.Printf("\tNASA JPL URL: %s\n", n.NasaJplURL)
fmt.Printf("\tPotentialy hazardous: %t\n", n.IsPotentiallyHazardousAsteroid)
fmt.Printf("\tMiss distance: %s km\n\n", n.CloseApproachData[0].MissDistance.Kilometers)
}
fmt.Printf("\n")
}
