The Hypatia II crew started the day with an EVA at Barrainca Butte, where the crew geologist, Dr. Marina Martínez, had the opportunity to collect geologic samples using the VANTA, a portable X-ray fluorescence analyzer kindly provided by Evident. With this instrument, she aims to optimize sample-return missions by obtaining compositional analyses in situ that allows to collect only those samples with the highest scientific value and the widest range of lithologies. This approach also seeks to apply geoconservation practices on Mars and the Moon. The Scientist and Health Safety officer, Dr. Estel Blay, and the journalist, Dr. Jennifer García Carrizo, accompanied her to document her work in the field. They returned safely to the base after a walk in the spectacular Martian landscape.
To honor the International Day of Women and Girls in Science, the crew made public their scientific and artistic project, which they have been working through several EVAs. A 40×40 meter cross was created in the martian landscape, to be captured by satellites in low Earth orbit.
Pythagoras and the method used by the ancient Egyptians to measure agricultural fields when the Nile River flooded, helped the crew to mark the region to deploy the macro-piece of art. The deployment was physically very demanding due to a tight timeline, as a consequence of adverse weather conditions during the first week on Mars. Moreover, the astronaut equipment, which weighs approximately 15 kilos, including gloves and other elements that hinder mobility, did not facilitate the task. The crew has undoubtedly done a great job. This action was part of an awareness online campaign #WomenLeaveTheirMark, which seeks to highlight the research of women scientists in the progress of science and knowledge.
