🚀 Quick Start

---

To use this package, you will need a free API key from api.nasa.gov.

1. Fetching the Astronomy Picture of the Day (APOD)

const nasa = require('@engineermapatac/event-horizon-js');

const API_KEY = 'DEMO_KEY'; // Replace with your actual NASA API key

async function getTodayInSpace() {
    try {
        // Fetch today's picture
        const data = await nasa.getAPOD(API_KEY);
        console.log(`Title: ${data.title}`);
        console.log(`Image URL: ${data.url}`);
        console.log(`Explanation: ${data.explanation}`);
        
        // You can also fetch a specific date (YYYY-MM-DD)
        const pastData = await nasa.getAPOD(API_KEY, '1995-06-16');
        console.log(`Past Image URL: ${pastData.url}`);
    } catch (error) {
        console.error("Error fetching APOD:", error);
    }
}

getTodayInSpace();

2. Fetching Mars Rover Photos (Curiosity)

const nasa = require('@engineermapatac/event-horizon-js');

const API_KEY = 'DEMO_KEY'; 

async function getMarsPhotos() {
    try {
        // Fetch photos from Martian Sol 1000
        const data = await nasa.getMarsPhotos(API_KEY, 1000);
        
        console.log(`Found ${data.photos.length} photos.`);
        if (data.photos.length > 0) {
            console.log(`First Photo URL: ${data.photos[0].img_src}`);
            console.log(`Camera: ${data.photos[0].camera.full_name}`);
        }
    } catch (error) {
        console.error("Error fetching Mars data:", error);
    }
}

getMarsPhotos();
