Who Is This For?

This workflow is designed for space enthusiasts, science educators, journalists, fact-checkers, and researchers who want to stay informed about near-Earth asteroid threats while filtering out media sensationalism. It's also valuable for anyone studying how different regions cover space-related news.

What It Does

This workflow creates an automated planetary defense monitoring system that:

  • Scans NASA's Near Earth Object database for potentially hazardous asteroids over a 7-day window
  • Searches news coverage across three regions (US, Japan, EU) to compare media reporting
  • Uses AI (GPT-4o-mini) to fact-check news claims against official NASA data
  • Detects misinformation and measures media sensationalism levels
  • Generates visual charts comparing actual threat levels vs media panic
  • Sends alerts through multiple channels (Slack, Discord, Email)
  • Logs all alerts to Google Sheets for historical analysis

How It Works

  1. Trigger: Runs daily at 9 AM or on-demand via webhook
  2. NASA Data Fetch: Retrieves 7-day asteroid forecast from NASA NeoWs API
  3. Threat Analysis: Identifies potentially hazardous asteroids and assigns alert levels (LOW/MEDIUM/HIGH)
  4. News Search: Searches news in US, Japan, and EU using Apify's Google Search Scraper
  5. AI Fact-Check: GPT-4o-mini compares news claims against NASA data, detecting misinformation
  6. Visualization: Generates gauge charts for threat level and media panic, plus regional comparison bar chart
  7. Multi-Channel Alerts: Sends formatted reports to Slack, Discord, Email, and logs to Google Sheets

Set Up Steps

Estimated time: 15-20 minutes

  1. NASA API (Required): Get your free API key at api.nasa.gov
  2. Apify (Required): Create account and connect via OAuth
  3. OpenAI (Required): Add your API key from platform.openai.com
  4. Notification Channels (Choose at least one):
    • Slack: Create OAuth app and connect
    • Discord: Create webhook URL
    • Email: Configure SMTP settings
  5. Google Sheets (Optional): Create a sheet for logging with columns: Date, Alert Level, Hazardous Count, Threat Score, Media Panic Score, Misinformation Detected, Top Asteroid, Most Accurate Region

Requirements

  • NASA API key (free)
  • Apify account (free tier available)
  • OpenAI API key (paid)
  • At least one notification channel configured
  • n8n version 1.0+

How to Customize

  • Change scan frequency: Modify the Schedule Trigger node
  • Add more regions: Edit the "Configure Regional Search" code node
  • Adjust alert thresholds: Modify lunar distance threshold (currently 10) in "Analyze Asteroid Threats"
  • Disable channels: Simply remove connections to notification nodes you don't need
  • Customize messages: Edit the "Format Multi-Channel Messages" node
