This update is called 'Distant Observations' and features two observation payloads the Himawari and the Akari, plus ESA's Vega rocket.

Small, versatile, and efficient β€” the Vega launch system is Europe’s way of launching light satellites to multiple orbits in a single launch. It's a cool addition to the game and looks spectacular standing on the launch pad ready for action.

The Himawari and Akari are both Japanese payloads but with very different purposes. Himawari series satellites provide data observations to support weather forecasting, where as the Akari was an infrared astronomy telescope designed to survey the entire sky and help further our understanding of the universe around us. It's neat to have one advanced observations payload pointing to earth, the other out into space!

  1. SPOT Satellite mission
  2. Rockets Nippon 1 and Nippon 2

[h2]What are we adding and why?[/h2]
We're adding the SPOT, which is an earth observation satellite used by the European Space Agency (ESA). The purpose of the SPOT series of satellites is to improve the knowledge and management of Earth by exploring the planet's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena. Since the launch of SPOT 1 in 1986, the series of satellites have been providing high-resolution, wide area optical imagery for the European Space Agency (ESA) which it shares with its partners around the world. It's a great payload to use in Mars Horizon for earth observation missions, and also gives an ESA playthrough a little more flavour!

We decided to add the Nippon 1 and Nippon 2 because they were so fundamental in what would become the Japanese Space Agency's earlier successes. These liquid propellant rockets assisted Japan in launching satellites from the 1970's all the way up to the present day, and are perfect for undertaking low payload weight request missions in Mars Horizon in a Japan playthrough.

Check out our blog for more information about these vehicles, or jump straight into Mars Horizon and test them out for yourself!
