Space Radar

A space news aggregation and analysis platform

Space Radar automatically collects stories from major space and astronomy news sources, removes duplicates through clustering, and provides summaries with relevance scoring. Built with Python and Flask.

Features

News Processing

• Multi-source aggregation: Fetches from NASA, ESA, SpaceNews, JPL, and other space news sources
• Duplicate detection: Uses clustering algorithms to identify and merge similar stories
• Automated summarization: Generates summaries and extracts key information
• Story ranking: Scores stories by source reliability, recency, and content analysis

Web Interface

• Clean design: Minimalist layout with serif typography
• Expandable cards: Click to expand stories for full details
• Responsive: Works on desktop, tablet, and mobile
• Trending topics: Scrolling carousel of current space topics

Data Pipeline

• Automated processing: Scheduled data collection and analysis
• Error handling: Retry logic and failure recovery
• Logging: Tracks processing success and failures
• REST API: JSON endpoints for accessing processed stories

Technology Stack

Backend

• Python 3.9+: Core application logic
• Flask: Web framework and API
• Sentence Transformers: Text embedding and similarity analysis
• Scikit-learn: Clustering and ML algorithms

Installation

Prerequisites

• Python 3.9 or higher
• pip package manager
• Virtual environment (recommended)

Setup

1. Clone the repository

   git clone https://github.com/nirvaankohli/space-radar.git
   cd space-radar

2. Create virtual environment

   python -m venv .venv
   
   # Windows
   .venv\Scripts\activate
   
   # macOS/Linux
   source .venv/bin/activate

3. Install dependencies

   pip install -r requirements.txt

4. Environment configuration

   # Create .env file
   echo "API_KEY=your_llm_api_key_here" > .env

5. Run the application

   python app.py

Visit http://localhost:5000 to access the Space Radar interface.

Usage

Web Interface

1. Browse Stories: View the latest space news in a card layout
2. Expand Details: Click any story card to see full content
3. Trending Topics: Browse the carousel for current space topics
4. Story Scores: See relevance scores based on content analysis

API Endpoints

• GET /: Main web interface
• GET /api/stories: JSON feed of processed stories
• POST /run_pipeline: Trigger manual data processing

Data Pipeline

# Run the complete data pipeline
python data_pipeline.py

# Process text analysis only
python agents/llm/build.py

Configuration

News Sources

Configure news sources in data/feeds.yml:

feeds:
  - name: "NASA"
    url: "https://www.nasa.gov/feed/"
    reliability: 0.99
  # Add more sources...

Scoring Weights

Adjust importance weights in agents/llm/build.py:

weights = {
    "llms": 0.6,        # Content analysis score
    "reliability": 0.2,  # Source reliability
    "recency": 0.2      # Time-based decay
}
