also known as

NEMESIS I,
[7]
or
P360
[8]
is a
classified
American
SIGINT
satellite,
[7]
which was launched in September 2009. The US government has not confirmed which of its intelligence agencies operate the satellite,
[9]
but leaked documents from the Snowden files point to the
NSA
.
[10]
The spacecraft was constructed by
Lockheed Martin
, and is based on the
A2100
satellite bus
,
[6]
using
commercial off-the-shelf
components.
[8]
The contract to build PAN was awarded in October 2006, with the satellite initially scheduled to launch 30 months later, in March 2009.
[11]
PAN was launched by
United Launch Alliance
using an
Atlas V
401 carrier rocket, with the serial number AV-018. The launch, from
Space Launch Complex 41
at the
Cape Canaveral Air Force Station
, occurred at 21:35 GMT on 8 September 2009, at the start of a 129-minute launch window.
[12]
PAN successfully separated from the rocket just under two hours after liftoff.
[13]
PAN has shown an unusual history of frequent relocations during the first 5 years of its operations, moving between at least 9 different orbital slots since launch. With each move, it was placed close to another commercial communications satellite.
[7]
From 2013 onwards it was located at 47.7 deg E., over East Africa, staying in that position for several years. In February 2021 it started a slow drift eastwards.
