Orbital ATK Concludes
Eight Years of Comprehensive NFIRE Satellite
Mission Support
September 28, 2015
Orbital ATK, Inc. announced it concluded
eight years of mission support for the Near
Field Infrared Experiment (NFIRE) satellite with
the decommissioning of the spacecraft on August
5, 2015.
Sponsored by the U.S. Missile Defense Agency (MDA) and built
at Orbital ATK’s satellite manufacturing facility in Gilbert,
Arizona, NFIRE was originally designed as a one-year mission to
collect data from exhaust “plume” observations of boosting
rockets with the intent to advance launch detection and tracking
systems. The addition of the Laser Communications Terminal (LCT)
expanded NFIRE’s mission to assess viability of
satellite-to-satellite high speed communication links. During
its eight years on orbit, NFIRE helped advance the
state-of-the-art ballistic missile detection system,
accomplished bi-directional satellite laser communications at
will and boosted international collaboration with Germany.
“NFIRE is an example of a defense satellite that far exceeded
its original intent and became a ‘shining star’ program of the
Missile Defense Agency,” said Rick Kettner, Gilbert Site Manager
for Orbital ATK. “The value of the NFIRE team’s hard work and
data not only resulted in annual mission extensions from one
year to eight, but also served as a pathfinder for sustaining
systems like the Space Tracking and Surveillance System (STSS)
and Germany’s ongoing Laser Communications Terminal
applications.”
NFIRE launched in April 2007 aboard an Orbital ATK Minotaur I
from Wallops Island, Virginia. Orbital ATK was the system
integrator for the NFIRE mission, with responsibility for the
design and manufacture of the defense satellite, based on the
company’s flight-proven LEOStar™ spacecraft architecture. Other
contributions included payload integration, full satellite
system testing, configuration of two ground mission operation
centers and on-orbit operations support. Orbital ATK also led
the mission assurance and systems engineering integrated product
teams. After in-orbit testing was completed, the company turned
the satellite over to the MDA for primary management.
NFIRE’s primary instrument has been the Track Sensor Payload,
which has been able to collect data on targets of opportunity
through precision detection and tracking despite environmental
background clutter (i.e., atmospheric variables, clouds,
land-sea visibility and more).
The secondary payload, the Laser Communications Terminal
(LCT), supported successful laser communications demonstrations
as part of a cooperative agreement between the U.S. and Germany.
The German government provided the LCT for NFIRE and flew a
sister spacecraft, the TerraSAR-X (TSX-1), with an identical LCT
on board to conduct space-to-space links and space-to-ground
experiments. Together, NFIRE and TSX-1 accomplished the first
data transfer between two spacecraft at a rate of 5.6 gigabits
per second.
“From November 2008 to April 2015, NFIRE successfully
executed more than 950 inter-satellite and satellite-to-ground
laser communications links with its Laser Communications
Terminal,” said Tawnie Harrison, Orbital ATK’s NFIRE Program
Manager. “I’m proud of the team and the many technical
accomplishments we achieved for our customer and partners over
the mission lifetime.”
The NFIRE decommissioning process encompassed three burns
that progressively lowered the satellite’s orbit, dumped its
fuel and left the spacecraft in a low-altitude orbit that will
lead to atmospheric re-entry. Currently, the MDA is not planning
a successor to NFIRE, but the mission’s legacy will continue
within next-generation missile detection systems.
