40-600: A telerobotic spacecraft, and something that had only previously been done on the Hubble Space Telescope servicing missions with direct human assistance. The goal is to extend its operational life by five years via in-orbit stationkeeping. After the Intelsat 901 mission ends, MEV-1 is designed to be able to dock and undock additional times, potentially enabling it to service additional satellites. ViviSat saw competition for space servicing business with
60-504: A June 2012 article in The Space Review , a number of approaches to satellite servicing were discussed. ViviSat's Mission Extension Vehicle was reported to operate at the "less complex" end of the technology spectrum, which could offer higher reliability and reduced risk to satellite owners. ViviSat believed their approach was simpler and could operate at lower cost than MDA, while having the technical ability to dock with "90% of
80-539: A plan submitted by Orbital ATK to use an MEV to service an Intelsat satellite, Intelsat 901 , that was originally launched to geostationary orbit in June 2001 for a planned in-service life of 13 years. That satellite had already been replaced in orbit. The first MEV, MEV-1 , was then planned to launch with Eutelsat 's Eutelsat 5 West B commsat, no earlier than 2019. MEV-1 also needed a licence from National Oceanic and Atmospheric Administration (NOAA). The NOAA license
100-644: A small-scale in-space satellite-refueling spacecraft . In the joint venture, ATK was to be responsible for the technical design, production and operation of the satellite, and US Space would be responsible for the financing and business-side of operations. By March 2012, ViviSat was finalizing its design and was "ready to build" the servicing spacecraft, but had announced no customers for the Mission Extension Vehicle services. In April 2014, ATK announced that it would merge its Aerospace and Defense Groups with Orbital Sciences Corporation . In
120-415: Is a spacecraft that extends the functional lifetime of another spacecraft through on-orbit satellite servicing . They are 2010s-design small-scale in-space satellite-refueling spacecraft first launched in 2019. The MEV spacecraft grew out of a concept proposed in 2011 by ViviSat, a 50/50 joint venture of aerospace firms US Space and Alliant Techsystems (ATK). The joint venture was created in 2010 for
140-519: Is required because the MEV-1 has cameras for docking that could also image the Earth, thus necessitating a remote-sensing license. In 2018, Orbital ATK was acquired by Northrop Grumman to become Northrop Grumman Innovation Systems . The MEV program continues under this new company. MEV-1 was set to launch on a Russian Proton-M rocket along with Eutelsat 5 West B satellite on 30 September 2019, but
160-499: The Baltimore, Maryland area, produces tactical missiles, defense electronics, and medium- and large-caliber ammunition. The division also produces fuzing and warheads for both tactical missiles and munitions; precision metal and composite structures for medium and large-caliber ammunition, military aircraft, ground vehicles, and missile systems; load, assembly, and pack (LAP) of medium caliber munitions; and propellants and powders for
180-559: The 2011 announcement of the Space Infrastructure Servicing (SIS) vehicle from MacDonald, Dettwiler and Associates (MDA). However, the two vehicles intended to operate with different technology approaches. Whilst the ViviSat design connects to the target satellite and uses "its own thrusters to supply attitude control for the target"., SIS MDA would open the satellite's fuel lines, refuel it, then depart. In
200-402: The 450 or so geostationary satellites in orbit", whereas MDA SIS could open and refuel only 75%. "In addition to extending the life of an out-of-fuel satellite, the company could also rescue fueled spacecraft like AEHF-1 by docking with it in its low orbit, using its own motor and fuel to place it in the right orbit, and then moving to another target". As of 2012 , ViviSat planned to use
220-670: The ATK A700 satellite bus . Northrop Grumman Innovation Systems Orbital ATK Inc. was an American aerospace manufacturer and defense industry company. It was formed in February 9, 2015 from the merger of Orbital Sciences Corporation and parts of Alliant Techsystems (ATK). Orbital ATK designed, built, and delivered rocket engines , military vehicles , firearms , autocannons , missiles , ammunition , precision-guided munitions , satellites , missile approach warning systems , launch vehicles and spacecraft .

#1732800733258240-652: The Flight Systems Group includes the Pegasus , Minotaur , and Antares launch vehicles as well as solid-propulsion and aerostructures programs. The company also operates a Lockheed L-1011 TriStar wide body jetliner, which is named Stargazer and is used to air launch Pegasus rockets carrying payloads into space. The Stargazer aircraft is also used for testing under specific programs. The Flight Systems Group became part of Northrop Grumman Space Systems on January 1, 2020. The Defense Systems Group, based in
260-456: The acquisition with conditions on June 5, 2018, and on June 6, 2018, Orbital ATK was renamed Northrop Grumman Innovation Systems. With Northrop Grumman's reorganization of its divisions effective January 1, 2020, Northrop Grumman Innovation Systems was split, with most of the sector merging with other Northrop Grumman businesses into a new Space Systems sector. Based in Chandler, Arizona ,
280-416: The launch was postponed to 9 October 2019 due to issues with the integration of control systems of Briz-M orbit insertion stage and the satellites. MEV-1 was launched on 9 October 2019. MEV-1 rendezvoused with Intelsat 901 on 25 February 2020 at 07:15 UTC, and by April 2020 had repositioned the commsat so that it could come back on line in its designated geosynchronous spot, a space industry first for
