Mid-Atlantic Regional Spaceport (MARS) is a Virginia Spaceport Authority-owned and operated FAA-licensed commercial spaceport on NASA’s Wallops Flight Facility at Wallops Island, Virginia. MARS provides multi-user launch, payload-processing, integration, control and range support for small- and mid-class vehicles. Its current facilities include Launch Pad 0-A for liquid-fuel, multi-customer missions; Launch Pad 0-B for solid-fuel small- and mid-class vehicles; Pad 0-C support systems; integration and control; payload processing; and the MARS UAS airfield. Rocket Lab’s Neutron Launch Complex 3 is co-located with its Electron Launch Complex 2. This is a controlled federal-facility tenant site, not a general walk-in visitor attraction; public launch viewing is available from the NASA Wallops Visitor Center when mission and safety guidance allow. Confirm current schedules and access before travel. Facility reference: 33415 Chincoteague Road, Wallops Island, Virginia 23337, United States.
