NASA Tests Air Traffic Surveillance Technology Using Its Pilatus PC-12 Aircraft
- NASA is evaluating an Automatic Dependent Surveillance-Broadcast (ADS-B) system’s ability to prevent collisions in a simulated urban environment.
- Using its Pilatus PC-12 aircraft, researchers are investigating how ADS-B systems could handle the demands of air taxis flying at low altitudes through cities.
- The challenge for ADS-B systems is consistent signal coverage in urban areas, which can be interrupted by distance or interference and potentially cause collisions.
- Researchers established a test zone at NASA’s Armstrong Flight Research Center in Edwards, California, on Sep 23 and 24, 2024, and flew in a grid pattern over four ADS-B stations to collect data on signal coverage, which will inform future placement of additional ground stations.
- Brad Snelling, Vehicle Test Team Chief Engineer for NASA’s Air Mobility Pathfinders project said, “We can use the test results to help us configure the equipment to reduce signal loss when we conduct future air taxi flight tests.
- NASA's research in ADS-B signals will help revolutionize U.S. air transportation.
- NASA pilots and crew from Armstrong and Glenn Research Centers undertook a series of familiarization flights, including several approaches and landings, to prepare for ADS-B test flights.
- In June, researchers flew the Pilatus PC-12 and found a consistent ADS-B signal between the aircraft and communication antennas mounted on the roof of the center’s Aerospace Communications Facility.
- NASA will use the results of this research to design infrastructure to support future air taxi communication, navigation, and surveillance research and to develop new ADS-B-like concepts for uncrewed aircraft systems.
- NASA’s research in ADS-B signals and other communication, navigation, and surveillance systems and the results of this research will help to design infrastructure to support future air taxi communication, navigation, and surveillance research.

Several Double Planetary Disks Found
- Recently, astronomers used radio and optical telescopes to study double planetary disks around binary stars, showing differences in their disks whether they formed together or not.
- The collection of material around binary stars, called "protoplanetary disks," formed from raw materials as parent stars.
- DF Tau, situated over 400 light-years away in the constellation Taurus, has peculiar characteristics where its ‘double’ planetary disks show distinct differences and only the primary star has an active inner disk.
- The research around the system suggests that the dispersal of circumstellar disks is complex and there is more to disk evolution than just time.
- Planetary disks are giant wheels spinning in molecular clouds forming planetesimals and ultimately planets.
- Finding planetary disks around other stars gives an insight into the early stages of the formation and evolution process.
- The survey conducted by the astronomers will shed some light on the process of planetary formation in paired disks and help understand their evolution.
- Their data may highlight the individual viscosities of the disks and the presence of a substellar companion carving out gaps around the secondary star to explain the dissipation differences.
- Research surrounding the processes of planetary formation and circumstellar evolution should help understand the realms with respect to planet formation.
- Checking out more binaries should give us a better understanding of binary star and planet evolution.

Getting To Mars Quickly With Nuclear Electric Propulsion
- NASA is exploring the idea of using nuclear electric propulsion to shorten the travel time to Mars for a crewed mission. Engineers at NASA’s Langley Research Center are working on a nuclear electric propulsion system that could bring Mars within reach in about two years. The system is called the Modular Assembled Radiators for Nuclear Electric Propulsion Vehicles (MARVL). MARVL is connected to NASA’s goal of developing a Mars Transit Vehicle, aka Deep Space Transport, in the next decade or by the late 2030s. One of the system’s components is its heat dissipation system, designed as an array about the size of a football field once deployed. Folding the entire system up into a small enough payload to fit inside a rocket fairing isn’t an option, so engineers are looking to assemble the system in space with robots.
- Space robotics is advancing and will play a larger role as the future unfolds. Making the heat dissipation system modular and assembling it in space with robots opens up new possibilities. The entire idea is an engineering challenge, but one that’s not that far out of reach. NASA’s Langley Research Centre played an important role in the development of the Apollo Lunar Module and contributed to other endeavours like the Hubble Space Telescope and the Viking Mars Lander. Space technology and research are one of their primary focuses.
- The MARVL project team is producing a vehicle from the ground up that is designed to be launched in pieces and assembled in space. The Nuclear Electric Propulsion system wasn’t the only one under consideration. NASA also considered the Nuclear Thermal Propulsion system. They also considered a “quad-wing” design for the NEP system. However, the “quad-wing” system required more propellant, and the deployment systems in that design were heavy and complicated. It also required a larger surface area.
- The Bi-Wing design has several advantages over the Quad-Wing design. It can be launched piece by piece in commercial launch vehicles without the need for the SLS, and the rocket payload fairing doesn’t restrict the radiator size. NASA gave the MARVL project team two years to develop the idea. By then, the team hopes to have a small-scale ground demonstration ready.

A Fast Radio Burst Came From an Old, Dead Galaxy
- A new study published in The Astrophysical Journal Letters reveals that a repeating fast radio burst (FRB) originated from the edge region of an 11 billion-year-old galaxy.
- The FRB, named FRB 20240209A, was observed 21 times between February and June, allowing astronomers to pinpoint its source located two billion light-years away.
- The discovery challenges the belief that FRBs are caused by young magnetars and suggests that merging magnetars in a dense globular cluster may generate FRBs.
- This finding indicates that the astrophysical processes behind FRBs are more diverse than previously thought.

Tracing the Big Ideas that Led to Webb
- Members of the James Webb Space Telescope original design team has released a brief history of document called Theory of Operations which describes the design decisions, how they were made and implemented.
- The development of a successor to the Hubble space telescope appeared to require a 30-year lobbying, building and testing scenario.
- Initial design requirements were hazy but a consensus between innovators supposed that the telescope should be able to look into the infrared spectrum.
- Fortunately, NASA’s Advanced Concepts Office had already worked on several designs for a next-gen space telescope.
- During the late 1980s and early 1990s, several workshops were held to discuss different design trade-offs in the Next Generation Space Telescope’s design.
- Budget constraints at the Space Telescope and Science Institute proved to be a challenge.
- An initial approach was the Very Large Space Telescope which was mainly Hubble with a bigger mirror.
- The telescope had originally been proposed back in 1986 and subsequently had several more preliminary design iterations.
- The NGST was designed to be located at the Earth-Sun L2 Lagrange point rather than on the Moon or in orbit around Earth.
- After design refinement, manufacturing, and testing, the JWST was launched successfully. It has been providing us with fascinating pictures from every corner of space.
