An Electronic Traffic Monitor for Airports 

If every commuter drove the same few roads at the same time every day, the traffic would be unbearable. That’s exactly what’s happening in the skies above the nation, known as national airspace (NAS). Multiple flights from different airlines try to use the most direct flight paths, converging on the same airports. With limited runway space, that causes jumbo-sized traffic congestion.  

“The majority of uncertainty in the NAS can be attributed to surface operations, and in particular, uncertainty related to when a flight will be available to push back from the gate,” said Jeremy Coupe of NASA’s Ames Research Center in Silicon Valley, California. To help develop a solution, NASA Ames focused on how to improve managing traffic on the ground and scheduling departures. 

Working with the Federal Aviation Administration (FAA), commercial airlines, and airports, NASA developed and tested a new program to manage airport traffic on the ground – the Integrated Arrival, Departure, and Surface (IADS) system. In 2022, the FAA began incorporating this system’s capabilities at 27 of the busiest airports in the country. 

Just as a traffic officer can prevent gridlock at a busy intersection, IADS is designed to prevent similar traffic tangles. The first test site for the program development was Charlotte Douglas International Airport in North Carolina, the second-busiest airport on the East Coast with only three runways. About 75% of those are connecting flights. 

Before IADS, one challenge the airport faced was a technology mismatch – the airport’s control tower used one software program and ground management used a different one, with no way to integrate them. A phone call was the most common way to notify each other about changes or problems. With approximately 115 aircraft on the ground at any time, a delay in communication could create complications. A plane leaving the gate before being notified of a delay could result in several planes waiting in line at the runway. 

“Knowing that you’re going to get where you need to go when the airline says it’s going to deliver you is what people stress about when they’re traveling, especially if they’re trying to make connections in an airport like Charlotte,” said Lee Davis, communications director for the airport. Many factors, including weather, influence timeliness, but making ground operations run predictably is fundamental. 

With near real-time data related to on-time departures and delays, airlines can actively address issues related to connections for crew, customers, and cargo. Whether it’s in space or the skies above, NASA innovations continue to make travel more efficient.

“I love my country. I love serving my country. I think that was ingrained in me in the military, where I grew to realize how lucky we are to live in America and have the freedoms that we have. When I returned from [my first duty station] in Germany, I separated from the Air Force for about nine months, but I missed it so much, I was like, ‘Well, I guess I could join the reserves.’ I did want to get my education. I was ready by then.

“So, I enrolled in school and went into the Reserves, and then 9/11 happened. That will change a person. I called my unit that afternoon and said, “Whatever you need, I’m ready.” I was activated supporting the mission, but I didn’t deploy like my husband. [9/11] is what touched my life more than anything: how quickly things can change in the blink of an eye. That’s what strengthened my respect of the Air Force core values: service before self and integrity, and excellence in all we do.

“Then, when I got pregnant, I thought I might want to be home, so I continued in civil service and just fell in love with my kids. That’s when my relationship with loving the Air Force changed. It evolved. I still value all that time I had and served and the lessons I learned growing up [in the Air Force]. The biggest thing I have and will continue to pass on to my kids is respect for your country, even if you don’t follow the route I did. Respect your country and the people who serve it.”

NASA Awards Contract for NOAA’s Next-Generation Space Weather Sensors

NASA, on behalf of the National Oceanic and Atmospheric Administration (NOAA), has selected Johns Hopkins University’s Applied Physics Laboratory of Laurel, Maryland, to build the Suprathermal Ion Sensors for the Lagrange 1 Series project, part of NOAA’s Space Weather Next Program.

This cost-plus-fixed-fee contract is valued at approximately $20.5 million and includes the development of two Suprathermal Ion Sensor instruments. The anticipated period of performance for this contract will run through Jan. 31, 2034. The work will take place at the awardee’s facility in Maryland, NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Kennedy Space Center in Florida.

The contract scope includes design, analysis, development, fabrication, integration, test, verification, and evaluation of the Suprathermal Ion Sensor instruments, launch support, supply and maintenance of ground support equipment, and support of post-launch mission operations at the NOAA Satellite Operations Facility.

The Suprathermal Ion Sensors will provide critical data to NOAA’s Space Weather Prediction Center, which issues forecasts, warnings and alerts that help mitigate space weather impacts, including electric power outages and interruption to communications and navigation systems.

The instruments will measure suprathermal ions and electrons across a broad range of energies, and will provide real-time, continuous observations to ensure early warning of various space weather impacts. They also will monitor ions to characterize solar ejections including coronal mass ejections, co-rotating interaction regions, and interplanetary shocks. Analysis of these spectra aids in estimating the arrival time and strength of solar wind shocks.

NASA and NOAA oversee the development, launch, testing, and operation of all the satellites in the L1 Series project. NOAA is the program owner that provides funds and manages the program, operations, and data products and dissemination to users. NASA and commercial partners develop, build, and launch the instruments and spacecraft on behalf of NOAA.

NASA, USAID Invite Media to Launch of New SERVIR Central America Hub

NASA and the U.S. Agency for International Development (USAID) invite media to the official launch celebration of the new SERVIR Central America regional hub, located in Costa Rica, on Tuesday, Dec. 3, at 11 a.m. EST. The event will be hosted by NASA SERVIR Program Manager Daniel Irwin, U.S. Ambassador to El Salvador William H. Duncan, and a representative from El Salvador’s Ministry of Environment and Natural Resources (MARN).

Central America is the latest addition to SERVIR’s global network, a NASA and USAID initiative that has been operating in Asia, Africa, and Latin America since 2005. 

Implemented by the Tropical Agricultural Research and Higher Education Center (CATIE), SERVIR Central America will strengthen climate resilience, sustainable resource management, and biodiversity conservation through satellite data and geospatial technology. The SERVIR Central America hub will support evidence-based decision-making at local, national, and regional levels, strengthening the resilience of more than 40 million people in one of the world’s most climate-vulnerable regions.

The event will be in Spanish with English translation available.

For press access and location details, please RSVP to Belarminda Quijano at belarminda@bqcomunicaciones.com by Monday, Dec. 2. NASA’s media accreditation policy is online. The event will be livestreamed.
