The '''''Morelos'' satellites''' are a series of [[Mexico|Mexican]] [[communications satellite]]s. The first two operated between 1985 and 1998 and provided telephony, data, and television services over the territory of the Mexican Republic and adjacent areas. The third is now part of the [[MEXSAT]] constellation (sister ship of the MEXSAT-1 lost during launch) but carries the ''Morelos'' name.

The original ''Morelos'' satellites were replaced by the [[Solidaridad Satellite System]] (''Solidaridad I'', launched 17 November 1993, and ''Solidaridad 2'', launched 17 October 1994) and, following privatisation, by the [[Satmex|Satmex Satellite System]].

===Morelos I===
''Morelos I'' was Mexico's first communications satellite. It was built and put into orbit under a contract from the [[Secretariat of Communications and Transport]] (SCT), the federal ministry responsible for the nation's communications systems.
'''Morelos I''' was Mexico's first communications satellite. It was built and put into orbit under a contract from the [[Secretariat of Communications and Transport]] (SCT), the federal ministry responsible for the nation's communications systems.
''Morelos I'', a [[Hughes Aircraft Corporation]] [[Hughes HS-376|HS-376]], was launched by the U.S. [[space shuttle]] ''[[Discovery (shuttle)|Discovery]]'' (mission [[STS-51-G]]) on 17 June 1985 and entered [[geostationary orbit]] at 113° W on 17 December 1985.

''Morelos II'' was launched in November 1985 and remained in service until July 1998. Built by the Hughes Aircraft Corporation for the SCT, it was launched by the space shuttle ''[[Atlantis (shuttle)|Atlantis]]'' on 27 November 1985; the mission, [[STS-61-B]], included [[Mexican]]-born astronaut [[Rodolfo Neri Vela]] as a payload specialist in its crew. ''Morelos II'' held a geostationary orbit at 116.8° W.

===Morelos III===
'''Morelos III''' (originally '''[[MEXSAT]] 2''') was launched on 2 October 2015 at 10:28 UTC on ''[[Atlas V]]'' 421 AV-059 and the 100th launch by the [[United Launch Alliance]]. The spacecraft is designed to provide L-band services to mobile 3G+ users and armed forces via a deployable 22m [[Reflecting telescope#Herschelian|Herschelian]] antenna dish with RF transceivers. It also has a 2m Ku-band dish of fixed geometry with a much simpler deployment sequence. The spacecraft is a [[Boeing]] 702HP GeoMobile spacecraft bus equipped with an RD-4 main engine for completing its ascent to geostationary orbit at 113° W from an ascent orbit of 4750 by 35800km inclined at 27° following the now-typical long duration two-burn profile of the ''Atlas V''.<ref>{{cite web

The Morelos satellites are a series of Mexican communications satellites. The first two operated between 1985 and 1998 and provided telephony, data, and television services over the territory of the Mexican Republic and adjacent areas. The third is now part of the MEXSAT constellation (sister ship of the MEXSAT-1 lost during launch) but carries the Morelos name.

The original Morelos satellites were replaced by the Solidaridad Satellite System (Solidaridad I, launched 17 November 1993, and Solidaridad 2, launched 17 October 1994) and, following privatisation, by the Satmex Satellite System.

Satellites[edit]

Morelos I[edit]

Morelos I was Mexico's first communications satellite. It was built and put into orbit under a contract from the Secretariat of Communications and Transport (SCT), the federal ministry responsible for the nation's communications systems. Morelos I, a Hughes Aircraft Corporation HS-376, was launched by the U.S. Space Shuttle Discovery (mission STS-51-G) on 17 June 1985 and entered geostationary orbit at 113° W on 17 December 1985.

Morelos II[edit]

Morelos II was launched in November 1985 and remained in service until July 1998. Built by the Hughes Aircraft Corporation for the SCT, it was launched by the Space Shuttle Atlantis on 27 November 1985; the mission, STS-61-B, included Mexican-born astronaut Rodolfo Neri Vela as a payload specialist in its crew. Morelos II held a geostationary orbit at 116.8° W.

Morelos III[edit]

Morelos III (originally MEXSAT 2) was launched on 2 October 2015 at 10:28 UTC on Atlas V 421 AV-059 and the 100th launch by the United Launch Alliance. The spacecraft is designed to provide L-band services to mobile 3G+ users and armed forces via a deployable 22m Herschelian antenna dish with RF transceivers. It also has a 2m Ku-band dish of fixed geometry with a much simpler deployment sequence. The spacecraft is a Boeing 702HP GeoMobile spacecraft bus equipped with an RD-4 main engine for completing its ascent to geostationary orbit at 113° W from an ascent orbit of 4750 by 35800km inclined at 27° following the now-typical long duration two-burn profile of the Atlas V.[1][2][3] It was originally intended to serve with the similar MEXSAT-1 Centenario spacecraft (which would have been at 116° W) lost during the 3rd stage failure of the 406th Proton, a launch vehicle of Proton-M/Briz-M configuration.[4]
