Esta es la primera imagen del Rover Perseverance de la NASA en la superficie de Marte desde la cámara del Experimento de Imágenes de Alta Resolución (HiRISE) a bordo del Mars Reconnaissance Orbiter (MRO) de la NASA muestra las muchas partes del sistema de aterrizaje de la misión Marte 2020 que puso al rover a salvo en tierra. La imagen fue tomada el 19 de febrero de 2021.

Setting the Standards for Unmanned Aircraft

From advanced wing designs, through the hypersonic frontier, and onward into the era of composite structures, electronic flight controls, and energy efficient flight, our engineers and researchers have led the way in virtually every aeronautic development. And since 2011, aeronautical innovators from around the country have been working on our Unmanned Aircraft Systems integration in the National Airspace System, or UAS in the NAS, project.  

This project was a new type of undertaking that worked to identify, develop, and test the technologies and procedures that will make it possible for unmanned aircraft systems to have routine access to airspace occupied by human piloted aircraft. Since the start, the goal of this unified team was to provide vital research findings through simulations and flight tests to support the development and validation of detect and avoid and command and control technologies necessary for integrating UAS into the NAS.  

That interest moved into full-scale testing and evaluation to determine how to best integrate unmanned vehicles into the national airspace and how to come up with standards moving forward. Normally, 44,000 flights safely take off and land here in the U.S., totaling more than 16 million flights per year. With the inclusion of millions of new types of unmanned aircraft, this integration needs to be seamless in order to keep the flying public safe.

Working hand-in-hand, teams collaborated to better understand how these UAS’s would travel in the national airspace by using NASA-developed software in combination with flight tests. Much of this work is centered squarely on technology called detect and avoid.  One of the primary safety concerns with these new systems is the inability of remote operators to see and avoid other aircraft.  Because unmanned aircraft literally do not have a pilot on board, we have developed concepts allowing safe operation within the national airspace.  

In order to better understand how all the systems work together, our team flew a series of tests to gather data to inform the development of minimum operational performance standards for detect and avoid alerting guidance. Over the course of this testing, we gathered an enormous amount of data allowing safe integration for unmanned aircraft into the national airspace. As unmanned aircraft are becoming more ubiquitous in our world - safety, reliability, and proven research must coexist.

Every day new use case scenarios and research opportunities arise based around the hard work accomplished by this incredible workforce. Only time will tell how these new technologies and innovations will shape our world.

Con pinceladas cósmicas de gas hidrógeno brillante , este hermoso paisaje celeste se despliega a través del plano de nuestra Vía Láctea y el centro de la constelación norteña Cygnus el Cisne. A la izquierda de Gamma Cygni , con la forma de dos alas luminosas divididas por un largo camino de polvo oscuro está IC 1318, cuyo nombre popular es comprensiblemente la Nebulosa de la Mariposa.
