Northrop Grumman's Cygnus capsule — dubbed the S.S. Katherine Johnson — should reach the International Space Station on Monday following its launch from Virginia's eastern shore. He noted that the space station flew over Virginia just 10 minutes ahead of Saturday's launch. The capsule also holds 120,000 tiny roundworms for a muscle experiment, as well as off-the-shelf computer equipment to increase data processing speed at the space station.

WALLOPS ISLAND, Va. – After having to reschedule the launch previously, the Antares NG CRS-13 is scheduled to launch Friday at 3:43 p.m. from Wallops Island. The only concern may come in the form of surface winds, which will be gusty at times this far west and possibly as far east as Virginia’s barrier islands. The purpose of the launch is to transport nearly 8,000 pounds of experimental equipment, along with food and supplies, to a crew aboard the International Space Station. If you look to the east, you should be able to see the vapor trails seemingly wiggle through the sky. If the launch is postponed, it may be rescheduled for Saturday.
