Mid-Atlantic Regional Spaceport
The Mid-Atlantic Regional Spaceport (MARS) is a commercial space launch facility located at the southern tip of NASA's Wallops Flight Facility on Wallops Island in Virginia, just east of the Delmarva Peninsula and south of Chincoteague, Virginia, United States.
The General Assembly of the Commonwealth of Virginia created the Virginia Commercial Space Flight Authority (VCSFA), also known as Virginia Space, in 1995 to promote the development of the commercial space flight industry, economic development, aerospace research, and Science, Technology, Engineering, and Math (STEM) education throughout the Commonwealth. 
In 1997, Virginia Space entered into a Reimbursable Space Act Agreement with NASA, which provided for permitted use of land on NASA Wallops Island for the MARS launch pads. Virginia Space also applied for and was granted an FAA license to launch to orbit. This led to the establishment of the Virginia Space Mid-Atlantic Regional Spaceport (MARS), located on the southern portion of NASA Wallops Island. MARS is approved for launch azimuths from 38° to 60°, making it an ideal location from which to launch to the International Space Station (ISS). 
In July 2003, Governors Robert Ehrlich of Maryland and Mark Warner of Virginia signed an agreement that directed the Secretary of Commerce and Trade of Virginia and the Secretary of Business and Economic Development of Maryland to form a working group to develop a concept and implementation plan for joint governance, operation, and administration of the commercial spaceport at Wallops Island. 
In 2007, NASA selected Virginia-based Orbital Sciences Corporation (Northrop Grumman) to participate in the Commercial Orbital Transportation Services (COTS) program and then selected Orbital for a follow-on Commercial Resupply Service (CRS) contract to build and demonstrate a new rocket, Antares, to resupply the International Space Station (ISS). The CRS contract authorized eight missions from 2012 to 2015 carrying approximately 20,000 kg of cargo to ISS as well as disposal of waste. These launches were to take place from the new state-of-the-art MARS Pad 0A. 
On MARS Pad 0B, VCSFA made modifications and upgrades to launch the NASA Lunar Atmosphere and Dust Environment Explorer (LADEE) mission to the Moon in mid-2013 on a new Orbital Sciences Minotaur V launch vehicle. Also in mid-2013, the USAF launched ORS-3 from MARS Pad 0B. 
MARS is one of only several sites licensed by the FAA Office of Commercial Space Transportation to launch to orbit. Additionally, Virginia is home to the NASA Langley Research Center (LARC) and National Reconnaissance Office (NRO), and as such is a recipient of a large portion of the Federal budget for Space. Finally, according to the Information Technology and Innovation Foundation, Virginia ranks first in the number of scientists and engineers as a percentage of the workforce, third in the concentration of high-tech jobs as a percentage of the workforce, and sixth in non-industry investment in research and development. 
The Mid-Atlantic Regional Spaceport has three active launch pads.
The Launch pad 0A (LP-0A) was built for the Conestoga rocket, which made its only flight in 1995.  The launch tower was subsequently demolished in September 2008,  and has now been rebuilt for use by the Northrop Grumman Innovation Systems Antares.  The pad modifications for Antares included the construction of a Horizontal Integration Facility for launcher/payload mating and a wheeled transporter/erector that will "roll out and erect the rocket on its launch pad about 24 hours prior to launch". 
Launch pad 0B (LP-0B) became operational in 1999,  and was subsequently upgraded with the construction of a mobile service tower, which was completed in 2004.  It remains active, and is currently used by Minotaur rockets.
The facility suffered significant damage during the 28 October 2014 Antares launch failure, according to NASA officials in the immediate aftermath.  Preliminary estimates for rebuilding the pad indicated the cost should be no more than US$20 million.  By May 2015, that estimate had been revised down to US$13 million and repairs were expected to be completed by September or October 2015 with the next planned launch in March 2016.  On September 30, 2015, the spaceport announced repairs on pad 0A had been completed. 
In October 2018, Rocket Lab announced that it had selected Mid-Atlantic as its second launch site, called Rocket Lab Launch Complex-2. The company began construction in February 2019, together with the Virginia Commercial Space Flight Authority (Virginia Space). The pad is located at the Mid-Atlantic Regional Spaceport (MARS) at NASA's Wallops Flight Facility. On December 12, 2019, Rocket Lab said it had built and completed Launch Complex-2 and is ready to support missions just 10 months later, a new launch pad near Pad 0A, with the first launch scheduled for the third quarter of 2020 . At a press conference on the same day at the NASA Wallops Flight Facility, the USAF Space Test Program was announced as the first customer for the Electron launcher. The mission will see a single research and development micro-satellite.  The new launch complex also has an integration facility.
