Watch live as Elon Musk unveils his vision for missions to Mars

SpaceX sent a cargo capsule with nearly 5,500 pounds of experiments and supplies on a three-day trip to the International Space Station on Sunday, firing the automated spaceship through low-hanging clouds and into orbit from the same launch pad where Apollo astronauts began voyages to the moon.

Scientists eager for answers to long-standing questions about the geology of Mars will get a lift Saturday with the blastoff from California of an Atlas 5 rocket with NASA’s InSight mission, a robotic landing craft that will take the pulse and temperature of the red planet.

The Starlink 10-30 mission will add 28 more satellites to SpaceX’s low Earth orbit megaconstellation. Liftoff of the Falcon 9 rocket from pad 40 at Cape Canaveral Space Force Station is set for 3:57 a.m. EDT (0757 UTC) on Monday.
