Mid-Atlantic Regional Spaceport Launch Pad 0

Launch Pad 0, Pad 0 or LP-0, also known as Launch Complex 0,[1][2] Launch Area 0 or LA-0, is a launch complex at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Virginia in the United States. MARS is located adjacent to NASA's Wallops Flight Facility (WFF),[1] which ran the launch complex until 2003. WFF continues to provide various support services to MARS launches under contract with the Commonwealth of Virginia.

Pad 0AEdit

LP-0A was first built for the failed Conestoga rocket program.[3] The original launch tower was subsequently demolished in September 2008.[4] A new pad facility was built from 2009-2011 for Orbital Sciences Taurus II, now renamed Antares.[5] 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.[5] The first launch of Antares occurred on April 21, 2013.[6]

The pad was reinforced with pilings and features a liquid fueling facility, flame trench, and deluge system for cooling and sound suppression. The pad is capable of supporting a gross liftoff weight of 453.6 metric tons (1,000,000 lb) and can launch payloads of up to 5,035 kilograms (11,100 lb) into low Earth orbit [7]

On October 28, 2014, an Orbital Systems Antares rocket, flying as mission Cygnus CRS Orb-3, crashed 6 seconds after takeoff and appeared to have done significant damage to the launch pad itself. On October 29, 2014, teams of investigators began examining debris at the crash site.[8] By May 2015, estimates had been revised down to around $13 million. At that time, NASA had committed $5 million, Virginia Commercial Space Flight Authority committed $3 million and Orbital ATK $3 million. Repairs were underway and planned to be completed by September 2015, but repairs were only funded up to August with Virginia CSFA requesting that Orbital provide the remaining $2 million. On September 30, 2015, the spaceport announced repairs on pad 0A had been completed.[9] The launch pad resumed flight operations with the Cygnus CRS OA-5 mission on October 17, 2016.[10]

Pad 0BEdit

LP-0B became operational in 1999,[11] and was subsequently upgraded in 2003 with the construction of a mobile service tower, which was completed in 2004.[12] It is active, and is currently used by Minotaur rockets. The first launch from LP-0B was of a Minotaur I in December 2006,[13] and was the first launch from the Mid-Atlantic Regional Spaceport.

Vector Space Systems announced on October 19, 2017 that their upcoming Vector-R rocket will be conducting three launches in the next two years,[when?] with an option for 5 additional launches, from pad 0B.[14]
