## What is HelloMars?

Hello Mars is a mission-style weather and atmosphere app for exploring surface conditions on Mars.

  Follow sol time, temperature, pressure, wind, dust, daylight, and seasonal context across important Mars locations including Jezero Crater, Gale Crater, Elysium Planitia, and Olympus Mons. The app turns Martian weather into a clear, visual experience with an
  operations dashboard, Mars atlas, science view, and data source explanations.

  Hello Mars is built for people who want to understand Mars as a real place, not just look at static facts. The Ops screen shows current-looking surface conditions, sol time, pressure, wind, UV, daylight, trend charts, and telemetry-style updates. The Atlas lets
  you compare regions across the planet. The Science screen explains atmospheric behavior, mission instruments, pressure, composition, and Earth comparisons. The About screen explains what the app is for and where the data comes from.

  The app is also transparent about Mars telemetry. Public Mars weather data is not available as a dependable minute-by-minute consumer feed. Readings are clearly labeled as archive-backed, modeled, or contextual, so the experience can feel alive without
  pretending every value is live sensor data.

  Hello Mars combines public mission archive context, rover instrument history, and local modeling to create a beautiful way to understand Martian weather, atmosphere, and place.

  Features:
  - Mission-style Mars weather operations dashboard
  - Sol clock and Martian daylight context
  - Temperature, pressure, wind, UV, dust, and seasonal indicators
  - Mars atlas with region comparison
  - Science view for instruments and atmospheric composition
  - Earth comparison for pressure, gravity, day length, and temperature
  - Transparent source labels for archive, modeled, and contextual readings
  - No account required
  - No ads
