Watch the Falcon 9 and Crew Dragon arrive at the launch pad (members only)

Standing in front of a shiny full-scale prototype of SpaceX’s Starship vehicle in South Texas, Elon Musk said Saturday night he wants the company’s gigantic next-generation rocket to fly into orbit within six months, a bold schedule that he acknowledged requires “exponential” improvements in design and manufacturing.

A Northrop Grumman Pegasus XL rocket is back at Cape Canaveral after a cross-country ferry flight Tuesday under an L-1011 carrier jet, ready for final checkouts and a countdown dress rehearsal before an airborne launch off Florida’s east coast Oct. 9 with NASA’s Ionospheric Connection Explorer satellite.

Two veteran spacemen embarking on a marathon yearlong mission in orbit must first sprint through a busy workday Friday — suiting up for liftoff, climbing into their Soyuz spaceship, then flying to the International Space Station.
