You can then click on the Next Page area at the bottom of the panel to change to station stats which include Atmosphere, Solar, Supplies/Orbit and Agency Flags stats panels.

The atmosphere, food and water supplies and orbit, are absolutely essential to keep the station flying and habitable. CO2 levels need to be kept in green conditions using the Vozdukh, and US CO2 scrubber components. Sometimes the CO2 scrubbers need to be turned on and off to maintain optimum atmospheric conditions. O2, Water, and Food can all be sent up to the station in supply missions, but buying an O2 Generator and a Water Reclamation Unit lets you go longer between supply missions and increases your station efficiency. You can boost orbit and maintain Attitude using the TORU in Zvezda, but it uses up your fuel, so a better long term solution might be to purchase the Z1 truss module, which has control moment gyros (CMGs) that allow the station to remain stable in orbit without expending as much propellant. Make sure you keep the orbit from getting too low, or your astronauts may abandon ship before the station reenters the atmosphere in a fiery blaze.

Note: Advanced players will want to build a self sustaining biosphere aboard the ISS where no life support equipment is necessary. This is really the only way to live for extended periods away from the Earth. Hint: animals absorb and use Oxygen and expel Carbon Dioxide. Plants on the other hand absorb and use Carbon Dioxide and expel Oxygen.

Most of the tasks needed to keep the astronauts happy are pretty easy to figure out, but here are some additional hints for starters:
