On Microlab’s initiative, NTUA ECE personnel participated in one of the two awarded teams at the NASA International Space Apps Challenge 2019 in the Piraeus Hub. The team named μGrace Anatomy, was led by E. Petrongonas and mentored by G. Lentaris. Based on the key idea proposed by microlab, the team worked collaboratively towards defining a mission to track changes in the underground waters in localised areas using a formation of 3 small satellites, while minimising the costs. At the end of the local competition, the team was awarded and qualified for the next phase of the competition as Global Nominees.
