While concrete production accounts for about 8% of global CO2 emissions, BSC provides a possible carbon-neutral alternative and is also easy to produce from Martian resources. The team created a payload to autonomously create these Martian bricks in 0g (aboard the ISS), 1g (resting on Earth), and 2g (continuously spinning in a centrifuge). After winning a NASA contract, our payload was sent to the [https://www.nasa.gov/mission_pages/station/main/index.html International Space Station] to test it's formation in 0g.
