NASA launched a robotic space lander bound for Mars on Saturday morning, beginning a journey to explore the deep interior of the red planet.
The InSight probe was carried into orbit from a launch site in California at around 4:05 a.m. local time.
An Atlas 5 rocket sent the probe hurtling towards Mars, a voyage which is expected to take around six months.
The early stages of the mission appeared to go off without a hitch at Vandenberg Air Force Base. A NASA video feed showed the rocket taking off, though the foggy, pre-dawn conditions made for a less spectacular launch than other space missions.
