Travel to Mars and the Moon had limitations due to the amount of material that had to be transported. A new device powered by algae partly changes the picture.

The International Space Station is an out of orbit laboratory that floats at 390 kilometers above the Earth’s surface. Astronauts are responsible for conducting a series of science experiments and improving facilities.

Staff arriving at the facilities last approximately six months. During this time, they are researching, improving the facilities, and getting plenty of exercise to counteract the side effects of the drug. low gravity.

The supplies are transported in a spaceship called Dragon. It is designed to transport both goods and people to orbit destinations. It has a pressurized section and seven seats for passengers.

To provide closed loop life support, they will start testing with a photobioreactor using algae. In this way, he seeks to support astronauts on long-term missions, whether on Mars or the Moon.

These types of missions are limited because they require a large amount of supplies and exceed the carrying capacity that a spacecraft can withstand with current technology.

Chlorella vulgaris.

It’s a seaweed green that appeared on our planet more than 2 billion years. It is made up of a single spherical cell and contains exceptional amounts of chlorophyll.

In the bioreactor, algae convert carbon dioxide into oxygen and biomass for fuel through photosynthesis. It is expected that the 30% of the crew’s food It is based on algae due to its high protein content.

the photobioreactor work with him Advanced Closed Loop System (ACLS). The system absorbs the carbon dioxide that astronauts breathe out and transforms it into oxygen through a process based on electrolysis.

The ACLS extracts methane and water from carbon dioxide in the cabin of the space station. In turn, the algae in the photobioreactor will use the remaining carbon dioxide to generate oxygen, creating a hybrid solution officially known as PBR @ ACLS.
