Space Telegram

This set of scripts downloads:

• photos of SpaceX launches
• EPIC photo from NASA
• APOD photo from NASA
• automatically publishes a random photo to the Telegram channel at a specified interval

How to install

This should be enough for quickstart:

• Python3 should be already installed.
• Create virtual environment (optional)

python -m venv .venv
source .venv/bin/activate

• Install all requirements:

pip install -r requirements.txt

• Create .env file in project directory and copy-paste this:

NASA_API_TOKEN=<ENTER YOUR NASA API TOKEN HERE>
TELEGRAM_TOKEN=<ENTER YOUR TELEGRAM BOT TOKEN HERE>
TELEGRAM_CHAT_ID=<ENTER TELEGRAM CHAT_ID WHERE PHOTOS WILL BE PUBLISH>

How to run scripts

Each of the photo services has its own script that can work independently. Also, there is a script that can download photos from three services at the same time. And a script was written separately that runs and publishes photos to the Telegram channel with a specified time interval

fetch_nasa_daytime_photos.py

The script downloads the specified number of Astronomy Picture of the Day (APOD) photos taken by NASA. By default, the script downloads 5 photos

python fetch_nasa_daytime_photos.py [-h] [-count COUNT]

options:

-h, --help show this help message and exit

-count COUNT Number of photos to download

fetch_nasa_epic_photos.py

The script downloads EPIC photo from NASA

python fetch_nasa_epic_photos.py

fetch_spacex_last_launch_photos.py

The script returns photos of SpaceX launches by id. If id is not specified, then the script returns the photos of the last launch. Example launch id: 5eb87ce3ffd86e000604b336

python fetch_spacex_last_launch_photos.py [-h] [-id ID] 

options:

-h, --help show this help message and exit

-id ID launch id

fetch_them_all.py

The script downloads photos from three services at the same time.

python fetch_them_all.py

posting_in_tg_channel.py

The script automatically posts photos every 'period' hours. If the 'period' parameter is missing, the publication occurs every 4 hours.

python posting_in_tg_channel.py [-h] [-period PERIOD]

options:

-h, --help show this help message and exit

-period PERIOD frequency of posting pictures in hours
