The DARPA Space Environment Exploitation (SEE) program seeks to develop new models and sensing modalities to predict and observe the dynamics of the near-earth space environment. The SEE program explores how to go beyond magnetohydrodynamic descriptions of the magnetosphere, ionosphere, thermosphere coupled system to include wave/wave, wave/particle, and particle/particle interactions while using the latest advances in high performance computing such as GPUs and TPUs.
DARPA’s Experimental Spaceplane program (formerly known as XS-1) aims to build and fly the first of an entirely new class of hypersonic aircraft that would bolster national security by providing short-notice, low-cost access to space. The program aims to achieve a capability well out of reach today—launches to low Earth orbit in days, as compared to the months or years of preparation currently needed to get a single satellite on orbit. Success will depend upon significant advances in both technical capabilities and ground operations, but would revolutionize the Nation’s ability to recover from a catastrophic loss of military or commercial satellites, upon which the United States today is critically dependent.

Military satellites are critical sources of communications and data for today’s operations environments. Through DARPA’s Phoenix program, useable antennas or solar arrays from retired satellites in geosynchronous orbit (GEO – 36,000 kilometers above earth) could be removed and potentially repurposed as components for new satellites to provide vital mission support.
Military commanders responsible for situational awareness and command and control of assets in space know all too well the challenge that comes from the vast size of the space domain. The volume of Earth’s operational space domain is hundreds of thousands times larger than the Earth’s oceans. It contains thousands of objects hurtling at up to 17,000 miles per hour.
The goal of the DARPA Launch Challenge is to demonstrate responsive and flexible space launch capabilities from the burgeoning industry of small launch providers. For nearly 60 years, the nation’s space architecture has been built around exquisite systems that are launched by large, expensive boosters. The development cycle with the systems is tedious, with a process driven by a desire to reduce risk, rather than deliver timely capabilities.
