Natural Satellites of Mars
Mars has two small, irregular moons named Phobos and Deimos. Phobos is closer to Mars and has a radius of about 11 kilometers. It orbits Mars three times each day and is so close that it appears to hang in the Martian sky for hours at a time. Deimos is farther from Mars and has a radius of about 6 kilometers. It orbits Mars once every 30 hours.
The origin of the satellites is disputed, but some theories suggest that they may have been captured by Mars’ gravity or formed from debris left over from the formation of the planet. Both satellites are heavily cratered and appear to be composed of a mixture of rock and ice.
Phobos Architecture
Phobos is a web application framework for Python developed by the Django Software Foundation. It features a clean and concise design, encouraging code reusability and consistency. Phobos uses the Model-View-Controller (MVC) architecture, separating the application logic (Model), the presentation layer (View), and the user interaction (Controller). Some key architectural features of Phobos include:
- URL routing: URLs are mapped to specific controllers and actions, providing a clean and organized way to handle user requests.
- Django-like ORM: Phobos features an Object-Relational Mapper (ORM) similar to Django’s Model layer, simplifying database interactions and data manipulation.
- Template engine: Phobos uses the Jinja2 template engine, allowing developers to easily create dynamic and flexible web pages.
- Form handling: Form validation and processing are simplified through the built-in form handling capabilities.
- Request-response cycle: Phobos follows a clear request-response cycle, handling incoming HTTP requests, processing them, and generating responses.
