Astronaut Away Team Training At Tinguaton

After receiving feedback from the science backroom, astronauts Takuya Onishi (JAXA), Thomas Pesquet (ESA) and Jessica Wittner (NASA) proceeded to sample small quantities of pyroclasts.

A giant volcano hiding in plain sight in one of Mars’ most iconic regions. The newly discovered giant volcano on Mars is located just south of the planet’s equator, in Eastern Noctis Labyrinthus, west of Valles Marineris, the planet’s vast canyon system. The volcano sits on the eastern edge of a broad regional topographic rise called Tharsis, home to three other well-known giant volcanoes: Ascraeus Mons, Pavonis Mons, and Arsia Mons. Although more eroded and less high than these giants, the newly discovered volcano rivals the others in diameter, which is about 450 km (280 miles) (red dashed circle in this picture). Possible buried glacier ice is also reported under a relatively recent volcanic deposit within the perimeter of the eroded volcano, making the area attractive for the search for life and future robotic and human exploration.

Giant Volcano Discovered On Mars

by Keith CowingMarch 13, 2024March 13, 2024

A deeply eroded giant volcano, active from ancient through recent times and with possible remnants of glacier ice near its base, had been hiding near Mars’ equator in plain sight. […]
