NASA’s Mars Science Laboratory mission will deliver the nearly 2,000-pound (1-ton), car-size robotic roving laboratory to the surface of Mars at 10:31 p.m. PDT Aug. 5 (1:31 a.m. EDT Aug. 6). Curiosity’s landing will mark the start of a two-year prime mission to investigate whether one of the most intriguing places on Mars ever has offered an environment favorable for microbial life.

That’s 7:31 p.m. HST, prime time for me. Woohoo!
