The Air Force Research Laboratory's (AFRL) Demonstration and Science Experiments (DSX) free-flying satellite, built on a spacecraft platform designed and developed by Sierra Nevada Corporation (SNC), is on-orbit and successfully performing experiments. DSX is the latest innovative satellite program from SNC, the global aerospace and national security contractor owned by Chairwoman and President Eren Ozmen and CEO Fatih Ozmen.

"SNC is expanding its satellite portfolio and the DSX spacecraft platform is a perfect example of how we can offer great technology and platforms that are cost-effective, efficient and help our customers achieve their strategic goals," said SNC's CEO Fatih Ozmen.

The DSX platform provides a free-flying Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) platform for AFRL to better understand the dynamics of waves and particles in radiation, enabling better specification, forecasting and reducing impact of the harsh radiation environment of medium-Earth orbit (MEO).

DSX experiments include the following:

+ The Wave Particle Interaction Experiment (WPIx): Investigate the influence of very-low frequency (VLF) radio waves on particle dynamics.

+ Space Weather Experiments (SWx): Measure and map the distributions of energetic protons, electrons and low-energy plasma in the inner magnetosphere to improve environment models for spacecraft design and operations.

+ Space Environment Effects (SFx): Determine the MEO environmental effects on electrical components to launch as a secondary payload with primary missions requiring an EELV.

This integrated system represents the continued growth in SNC spacecraft from proven low-Earth orbit (LEO) constellations to developing Geostationary Equatorial Orbit (GEO) spacecraft and now increasing capability in MEO.

"Our Space Mission Systems team is excited to add both a MEO platform and free-flying ESPA spacecraft to our product line. Given the need for Command, Control, Communications, Intelligence, Surveillance and Reconnaissance systems (C3ISR) and enhanced resiliency, a platform like this can enable new capability for national defense customers in highly-elliptical orbit, MEO and GEO," said Joel Nelson, senior director of programs for SNC's Space Mission Systems business unit.

DSX launched June 25th on the Space Test Program-2 (STP-2) mission aboard the SpaceX Falcon Heavy launch vehicle and is expected to be on-orbit for one year.

Firefly Aerospace Provides a DREAM Payload Opportunity
Cedar Park TX (SPX) Jun 19, 2019
The quest for space travel inspires STEM interest like no other endeavor. Firefly has promoted that interest by opening its doors to youth though Firefly Academy, the Base 11 Space Challenge, and the Firefly International Rocket Event (FIRE). Today Firefly is taking their STEM commitment literally to the next level by announcing a global competition to host academic and educational payloads, free of charge, on the inaugural flight of the Firefly Alpha launch vehicle. "If America fails to gro ... read more
