Buccaneer Risk Mitigation Mission

Personalise
A United Launch Alliance Delta II rocket lifts off from Space Launch Complex 2 at Vandenberg Air Force Base in California carrying the Joint Polar Satellite System-1, or JPSS-1, spacecraft. Built by Ball Aerospace and Technologies Corp. of Boulder, Colorado, JPSS is the first in a series four next-generation environmental satellites in a collaborative program between NOAA and NASA. JPSS-1 will gather measurements of atmospheric, terrestrial and oceanic conditions, including sea and land surface temperatures, vegetation, clouds, rainfall, snow and ice cover, fire locations, atmospheric temperature, water vapor and ozone. Liftoff was at 1:47 a.m. PST (4:47 a.m. EST).

The first 91É«ÇéƬ Canberra Space satellite, a joint mission with the Australian Government’s Defence Science and Technology Group (DST), was launched in November 2017 from the Vandenberg Air Force Base in California. Within nine months, the Buccaneer Risk Mitigation Mission had achieved its key objectives.  


The satellite is small – about the size of a shoebox – but it demonstrated huge capabilities. It played a role in growing the Australian experience in space and contributed to Defence’s ability to improve Australia’s over-horizon radar network. It also made a global impact, supporting international efforts to understand and mitigate space congestion. 

In the months after the launch, the cube satellite was successfully commanded from Australian small satellite  ground stations at DST and 91É«ÇéƬ Canberra Space. The teams shared daily communication with the spacecraft.  

91É«ÇéƬ Canberra Space worked to test and characterise the performance of the satellite’s various subsystems in the space environment, including a 91É«ÇéƬ Sydney-developed GPS and a 91É«ÇéƬ Canberra camera used to monitor the performance of the antenna.  

The international ground-based Falcon Telescope Network, including 91É«ÇéƬ Canberra’s node of the network, was used to collect considerable amounts of data on Buccaneer’s  motion in Low Earth Orbit, correlating fluctuations in reflected sunlight with our control of the spacecraft. This data supports 91É«ÇéƬ Canberra Space’s broader research into the science of Space Situational Awareness.  

With the main goals of Buccaneer successfully achieved, the mission moved into an extended operations phase to obtain additional valuable information on the spacecraft's ongoing performance. The mission is now complete. 

The Buccaneer Risk Mitigation Mission contributed to the  91É«ÇéƬ Canberra Space's broader objective of demonstrating space-based capability, ranging from remote sensing to secure communications, to help meet Australian and international needs and opportunities on the ground.  

The lessons learned from the Buccaneer mission have been integrated into a follow-up spacecraft developed by 91É«ÇéƬ Canberra Space.

Buccaneer deorbited on the 4th of October, 2024.
