Let us connect your next big idea with engineering reality in a small CubeSat package that fits comfortably inside your budget.
Sensors & Subsystems
ASTRA™ helps our customers utilize low cost access to space by providing innovative CubeSat sensors and subsystems, engineering robust CubeSat system-designs based on your measurement and scientific needs, and providing in-depth mission analysis to ensure mission success and scientific closure.
In addition to our CubeSat systems, we specialize in miniaturization of sensor and other instrumentation as we continually strive to meet compatibility requirements for small platforms. ASTRA's work on recent CubeSat science missions demonstrates our ability to meet our customer's high demands and stringent requirements to provide the tools they need to achieve the goals of their missions.
Scintillation Observations and Response of the
Ionosphere to Electrodynamics
The SORTIE mission is a 6U NASA CubeSat mission with team members from ASTRA, Air Force Research Laboratory of Kirtland AFB, University of Texas, Dallas, COSMIAC, and Boston College.
The overall goal of the mission is to study the complex challenges in discovering the wave-like plasma perturbations in the ionosphere.
Perturbations in the ionospheric plasma density (shown above) most frequently appear in the form of discrete regions of waves. At low and middle latitudes, these perturbations are thought to provide the seeds for larger amplitude perturbations that may evolve non-linearly to produce irregularities. However, there is currently no comprehensive atlas of measurements describing the global spatial or temporal distribution of wave-like perturbations in the ionosphere.
Vertical ion velocity and plasma density perturbations from a C/NOFS orbit
SORTIE will provide the initial spectrum of wave perturbations which are the starting point for the RF calculation, provide measured electric fields which determine the magnitude of the instability growth rate near where plasma bubbles are generated, and will provide initial observations of the irregularities in plasma density which result from instability growth.
