The NASA Deep Space Network – or DSN – is an international network of antennas that supports interplanetary spacecraft missions and radio and radar astronomy observations for the exploration of the solar system and the universe. The network also supports selected Earth-orbiting missions.
The DSN currently consists of three deep-space communications facilities placed approximately 120 degrees apart around the world: at Goldstone, in California’s Mojave Desert; near Madrid, Spain; and near Canberra, Australia. This strategic placement permits constant observation of spacecraft as the Earth rotates, and helps to make the DSN the largest and most sensitive scientific telecommunications system in the world.
NASA’s scientific investigation of the Solar System is being accomplished mainly through the use of unmanned automated spacecraft. The DSN provides the vital two-way communications link that guides and controls these planetary explorers, and brings back the images and new scientific information they collect. All DSN antennas are steerable, high-gain, parabolic reflector antennas.

|Biography of Mr. Badri Younes,
Deputy Associate Administrator for Space Communications and Navigation,
|Mr. Younes is presently the Deputy Associate Administrator for Space Communications and Navigation (SCaN). He is responsible for NASA’s space communications and navigation infrastructure and services. Mr. Younes manages the SCAN Program Office at NASA Headquarters and oversees all NASA telecommunications and navigation projects and networks, including NASA’s Space Network (SN), Near-earth Network (NEN), and Deep Space Network (DSN). Mr. Younes is also responsible for the development of enabling technologies critical to meeting the Agency’s vision for an integrated SCaN architecture aligned with NASA’s future space exploration needs.
Prior to returning to NASA in 2007, Mr. Younes was the Department of Defense (DoD) Director for Spectrum Management with responsibility for spectrum policy and strategic planning and implementation for the DoD. Under his leadership, the Department has successfully negotiated major win-win agreements with the Federal Communications Commission, National Telecommunications Information Administration, and the U.S. private sector. He has successfully led the DoD spectrum management organization to become more proactive in addressing radio frequency (RF) and spectrum issues and has been instrumental in transforming the management and use of the electromagnetic spectrum within and outside the Department. He has played a lead and positive role in developing the Presidential Initiative Recommendations on Spectrum Reform.
Mr. Younes’ experience spans over twenty two years of leadership in microwave and RF systems engineering and technology. His interpersonal skills and rich linguistic ability have been instrumental in furthering U.S. objectives both nationally and abroad. He has over ten years of involvement in various forums of the International Telecommunications Union, and has provided direct support to U.S. ambassadors to three World Radio Conferences. Prior to joining the Department of Defense, Mr. Younes successfully managed the RF systems engineering and spectrum management for NASA’s Goddard Space Flight Center Space and Ground Networks.
Mr. Younes is a recipient of the 2005 Meritorious Presidential Rank Award. He is a member of Tau Beta Pi, engineering honor society. He holds a Masters in Electronics Engineering from Catholic University of America and had completed all his PhD requirements except for the dissertation.
