What will the first astronauts on Mars do. During their working hours, the astronauts will be busy with a number of basic tasks: construction, maintenance and research. In addition to work, they will also have time to relax.
The creation of a village on Mars involves the work of builders. Therefore, the first crew, in particular, will need to devote a lot of time to the arrangement of the village. The first astronauts on Mars will have to make an effort to make their new home a comfortable place to live.
Colonists will establish protected corridors between land and houses (of course, at first it will be a dome station). Additional solar panels are deployed and greenhouses are mounted, settling in the habitat. They will spend time sowing and cooking. They will also need to prepare a place for the second batch, the colonizers of Mars. Most likely the equipment of the second crew will be delivered together with the astronauts of the first settlers.
As soon as possible, the Earth will try to supply the settlement with methodologies for producing a suitable volume of products from mainly Martian materials in order to significantly expand the settlement. The goal of the first astronauts on Mars is to build a reliable living space to master the captured planet. It should be a spacious living environment where trees can grow. Such a large residential volume will make Mars a more pleasant place to live.
Maintenance will be critical to ensure the long-term functionality of all systems. The life of astronauts on an oxygen-free planet depends on the technologies existing in the settlement. All of these systems must be regularly monitored and maintained, otherwise life may die.
Research is also an important part of work on Mars, especially when the settlement is stable.
What is the history of Mars? Did Mars have a long wet period with liquid water or were there just a few wet years from time to time? When did the dramatic climate change occured? Is there life on Mars now? The first Martians will try to answer all these questions. The astronauts will conduct research and collect data for other researchers, and then transmit them to Earth.
At the same time, astronauts should also have time to relax. They can carry out most of the indoor activities that people can perform on Earth: read, play and chat, write and draw, work out in the gym and watch TV, use the Internet.
Due to the distance between Earth and Mars, there will be some restrictions regarding communications. This will lead to delays: Martian residents will have to pre-request movies or broadcast news that they want to see. There will always be a delay of at least three minutes, therefore people living on Mars will know the latest news a few minutes after the inhabitants of the Earth.
At the same time, they will be able to contact friends on Earth using video, voice or text messages (e-mail, WhatsApp, SMS). True dialogue in real time will be impossible because of the delay. At least, this comes from the basis of current technologies, but it is possible that this issue will be resolved over time.
