Perijove 16: Passing Jupiter

 

Watch Juno zoom past Jupiter. NASA's robotic spacecraft Juno is continuing on its now month-long, highly-elongated orbits around our Solar System's largest planet. The featured video is from perijove 16, the sixteenth time that Juno passed near Jupiter since it arrived in mid-2016. Each perijove passes near a slightly different part of Jupiter's cloud tops. This color-enhanced video has been digitally composed from 21 JunoCam still images, resulting in a 125-fold time-lapse. The video begins with Jupiter rising as Juno approaches from the north. As Juno reaches its closest view from about 3,500 kilometers over Jupiter's cloud tops the spacecraft captures the great planet in tremendous detail. Juno passes light zones and dark belts of clouds that circle the planet, as well as numerous swirling circular storms, many of which are larger than hurricanes on Earth. As Juno moves away, the remarkable dolphin-shaped cloud is visible. After the perijove, Jupiter recedes into the distance, now displaying the unusual clouds that appear over Jupiter's south. To get desired science data, Juno swoops so close to Jupiter that its instruments are exposed to very high levels of radiation.

BlueHalo wins $24 million Air Force contract for research and analysis of satellite vulnerabilities

April 21, 2024

 

WASHINGTON — The Air Force Research Laboratory awarded BlueHalo a $24.4 million contract to support the lab’s Satellite Assessment Center, an organization that models and analyzes the vulnerabilities of space systems.

 

BlueHalo, a defense contractor based in Arlington, Virginia, specializes in space, directed energy and autonomous systems technologies. The five-year contract was awarded by AFRL’s Directed Energy Directorate.

 

AFRL’s Satellite Assessment Center, located at Kirtland Air Force Base, New Mexico, evaluates the vulnerabilities of space vehicles to lasers and laser radiation.

 

The center tests laser effects on spacecraft components and materials and uses the data to build high-fidelity computer models used for predictive analysis and research.

 

The Satellite Assessment Center also develops tools that simulate sensor networks that track objects in space.

 

Directed-energy modeling

 

According to the April 19 contract announcement, BlueHalo will be tasked to “accelerate the advancement of the directed energy modeling, simulation and analysis, assessment expertise, and highly technical capabilities to safeguard strategic U.S. space interests.”

 

The contract also includes work on predictive analysis, satellite modeling, resiliency research and innovative testing environments to “assess natural and man-made directed energy effects on space systems.”
