A Falcon 9 rocket is to launch tonight with another batch of satellites for SpaceX’s Starlink internet service. Liftoff from pad 40 at Cape Canaveral Space Force Station occurred at 11:15 p.m. EDT (0415 UTC).

SpaceX plans to begin construction of a new rocket and spacecraft next year that could lead to human landings on Mars as early as 2024, scaling up technologies currently being perfected with the company’s Falcon 9 family of boosters to ensure reliability, reusability and, as a result, realistically low costs, founder Elon Musk said Friday.

Two Russian cosmonauts floated outside the International Space Station Thursday for a planned six-hour spacewalk to manually launch five small satellites, to test a variety of spacesuit upgrades, to retrieve an external experiment and to carry out routine inspections and maintenance.
