An integrated quad-band RF front end for high-reliability small satellite missions As ever-increasing demand for lower size, weight, and power (SWaP) and small satellite platforms continues, it drives development in all sectors, including high-reliability and deep-space technologies. In order to meet these demands, JHU/APL is working to evolve its flight-proven, low-SWaP Frontier Radio (FR) [1] system into even smaller, more efficient, and yet more powerful designs. The Frontier Radio has already successfully flown an S-band version on NASA s Van Allen Probes (VAP) mission, and an X/Ka-band version will la ...

The radio frequency telecommunications system for the NASA Europa clipper mission The NASA Europa Clipper mission, a partnership between the California Institute of Technology Jet Propulsion Laboratory (JPL) and the Johns Hopkins University Applied Physics Laboratory (APL), is currently in Phase B and scheduled for launch in 2022. A Jupiter orbiter, it will perform repeated flybys of the moon, Europa, to assess the icy moon’s structure and habitability. The spacecraft’s dual X/Ka-band radio frequency telecommunications subsystem has five primary functions: Provide spacecraft command capability ...

As part of a larger effort led by the Keck Institute for Space Studies at the California Institute of Technology, the Advanced Concepts Office at NASA’s George C. Marshall Space Flight Center conducted a study to assess what low-thrust advanced propulsion system candidates, existing and near term, could deliver a small, Voyager-like satellite to our solar system’s heliopause, approximately 100 AU from the center of the sun, within 10 years and within a 2025 to 2035 launch window. The advanced propulsion system tr ...

A review of the Solar Probe Plus dust protection approach The Solar Probe Plus (SPP) spacecraft will go closer to the Sun than any manmade object has gone before, which has required the development of new thermal and micrometeoroid protection technologies. During the 24 solar orbits of the mission, the spacecraft will encounter a thermal environment that is 50 times more severe than any previous spacecraft. It will also travel through a dust environment previously unexplored, and be subject to particle hypervelocity impacts (HVI) at velocities much larger than anything previously e ...

Hyper velocity protection developments on the solar probe plus mission The Solar Probe Plus (SPP) spacecraft will go closer to the Sun than any manmade object has gone before. The mission includes both solar flux and micrometeoroid environments much more severe than anything experienced by previous spacecraft. As a result, new analytical and testing methodologies are being developed to ensure the success of the mission. One of the major efforts is the development of an analytical approach for hypervelocity impacts (HVI) at speeds up to 300 km/s. To date, this dust study has made several notable ...
