The Missile Defense Agency deployed two tiny satellites to space June 30 that successfully began communicating with ground stations over the Fourth of July weekend, the first step on the way to an experiment that will eventually see them communicate with each other, a feat that could play a major role in the development of U.S. missile defense technology.
The CubeSat Networked Communicatio The Missile Defense Agency deployed two tiny satellites to space June 30 that successfully began communicating with ground stations over the Fourth of July weekend, the first step on the way to an experiment that will eventually see them communicate with each other, a feat that could play a major role in the development of U.S. missile defense technology.
The CubeSat Networked Communications Experiment (CNCE) Block 1, part of MDA's Nanosat Testbed Initiative (NTI), uses small, low-cost satellites to demonstrate networked radio communications between nanosatellites while in orbit.
Transmitting data between interceptors, sensors and communication systems is critical to a missile defense architecture that must quickly identify, track and destroy incoming enemy missiles before they reach their targets.
CNCE Block 1 will demonstrate technologies and capabilities including:
+ formation flying for small satellites;
+ Software-Defined Radios;
+ ad hoc networks;
+ communication performance in non-optimal orientations (non-optimal means the antennas aren't necessarily pointing in the best direction such as between the two satellites and/or a satellite and a ground node);
+ and common, open-source, ground command and control software.
MDA's NTI teams with other Department of Defense organizations, academia and small businesses to pursue a broad range of state-of-the-art technologies focused on reduced size, weight and power that can reliably operate in space.
Nanosatellites generally refer to a family of satellites approximately four to eight inches in width and diameter, four to 13 inches in length and weighing from two to 22 pounds. CubeSats are a type of nanosatellite.
The CubeSats went to space on a VOX Space, LLC (a subsidiary of Virgin Orbit) LauncherOne rocket as part of a payload-sharing arrangement with the DOD's Space Test Program. CNCE Block 1 is the first in a series of planned experiments. MDA will operate the CNCE Block 1 spacecraft for approximately 90 days with the potential to continue for up to one year.

Tactically Responsive Launch-2 payload launched into orbit
Livermore CA (SPX) Jul 05, 2021
When the U.S. Space Force's Tactically Responsive Launch-2 (TacRL-2) mission launched from Vandenberg Space Force Base on June 13, it carried a payload designed and built in record time by Lawrence Livermore National Laboratory (LLNL). LLNL provided a three-mirror reflective telescope and sensor for the payload, which they designed, integrated, tested and delivered within four months of the word "go." The Lab delivered the payload to its partners at Space Dynamics Laboratory (SDL) and the Air Forc ... read more
