Launch

SpaceX was contracted to launch AsiaSat 8, using a Falcon 9 v1.1 launch vehicle. The launch took place from Space Launch Complex 40 (SLC-40) at the

Cape Canaveral Air Force Station (CCAFS) on 5 August 2014 at 08:00 UTC.{{cite web|title=AsiaSat 8 Successfully Lifts Off|url=http://www.asiasat.com/asiasat/EN/upload/doc/pressrelease/news_e20140805.pdf|publisher=AsiaSat|date=5 August 2014|access-date=5 May 2021|url-status=dead|archive-url=https://web.archive.org/web/20150119133755/http://www.asiasat.com/asiasat/EN/upload/doc/pressrelease/news_e20140805.pdf|archive-date=19 January 2015}}[http://www.spacex.com/sites/spacex/files/spacex_presskit.pdf SpaceX AsiaSat 8 Press Kit] {{Webarchive|url=https://web.archive.org/web/20150119133624/http://www.spacex.com/sites/spacex/files/spacex_presskit.pdf |date=2015-01-19 }} 4 Aug 2014, accessed 5 Aug 2014

Falcon 9 upper stage

The Falcon 9 upper stage used to launch AsiaSat 8 is derelict in a decaying elliptical low Earth orbit that, {{asof|2014|08|13|lc=y}}, had an initial perigee of {{cvt|195|km}} and an initial apogee of {{cvt|35673|km}}. One month on, in September 2014, the orbit had decayed to an altitude of {{cvt|185|km}} at its closest approach to Earth, and by November 2014 had decayed to a {{cvt|169|km}} perigee.{{cite web|url=http://www.n2yo.com/satellite/?s=40108|title=FALCON 9 R/B|publisher=N2YO.com|access-date=5 May 2021}}

AMOS-7

In December 2016, Spacecom made a US$88 million four-year agreement with AsiaSat to lease AsiaSat 8 Ku-band. It is providing service at 4° West.{{cite news |url=http://spacenews.com/spacecom-borrowing-asiasat-8-to-cover-for-amos-6-satellite-lost-in-falcon-9-explosion/|title=Spacecom borrows AsiaSat 8 to cover for Amos-6 satellite lost in Falcon 9 explosion |publisher=SpaceNews|date=1 December 2016|access-date=5 May 2021}}
