A descoberta foi feita pela equipe científica do rover Perseverance, da agência espacial norte-americana. A rocha, que mede 1 metro por 60 centímetros, foi coletada em 21 de julho.

De acordo com o estudo, a pedra possui assinaturas químicas e estruturas que poderiam ter sido formadas por vida bilhões de anos atrás, quando a área continha água corrente.

A rocha apelidada de “Cheyava Falls” tem forma de ponta de flecha e é cheia de veios. Os cientistas acreditam que os sinais sejam um indicativo da presença de vida microscópica.

O robô explorava a cratera Neretva Vallis, um antigo vale fluvial de 400 metros de largura. O ambiente aparente ser esculpido pela água há muito tempo.
