NASA Moves Drone Package Delivery Industry Closer to Reality

Package delivery drones are coming to our doorsteps in the future, and NASA wants to make sure that when medication or pizza deliveries take to the skies, they will be safe.

In July, the Federal Aviation Administration (FAA) for the first time authorized multiple U.S. companies to fly commercial drones in the same airspace without their operators being able to see them the entire flight. Getting to this important step on the way to expanding U.S. commercial drone usage required considerable research into the concept known as flight that is Beyond Visual Line of Sight (BVLOS) – and NASA helped lead the way.

For BVLOS flights to become routine, trusted automation technology needs to be built into drone and airspace systems, since pilots or air traffic controllers won’t be able to see all the drones operating at once. To address these challenges, NASA developed several key technologies, most notably Unmanned Aircraft System (UAS) Traffic Management (UTM), which allows for digital sharing of each drone user’s planned flight details.

“NASA’s pioneering work on UTM, in collaboration with the FAA and industry, set the stage for safe and scalable small drone flights below 400 feet,” said Parimal Kopardekar, NASA’s Advanced Air Mobility mission integration manager. “This technology is now adopted globally as the key to enabling Beyond Visual Line of Sight drone operations.”

With UTM, each drone user can have the same situational awareness of the airspace where drones are flying. This foundation of technology development, led by NASA’s UTM project, allows drones to fly BVLOS today with special FAA approval.

Drones can fly BVLOS today at the FAA test site and at some other selected areas with pre-approval from the FAA based on the risks. However, the FAA is working on new regulation to allow BVLOS operations to occur without exemptions and waivers in the future.

The NASA UTM team invented a new way to handle the airspace — a style of air traffic management where multiple parties, from government to commercial industry, work together to provide services. These include flight planning, strategic deconfliction before flights take off, communication, surveillance and other focus areas needed for a safe flight.

This technology is now being used by the FAA in approved parts of the Dallas area, allowing commercial drone companies to deliver packages using the NASA- originated UTM research. UTM allows for strategic coordination among operators so each company can monitor their own drone flight to ensure that each drone is where it should be along the planned flight path. Test sites like Dallas help the FAA identify requirements needed to safely enable small drone operations nationwide.

NASA is also working to ensure that public safety drones have priority when operating in the same airspace with commercial drones. In another BVLOS effort, NASA is using drones to test technology that could be used on air taxis. Each of these efforts brings us one step closer to seeing supplies or packages routinely delivered by drone around the U.S.

NASA Scientific Balloon Flights to Lift Off From Antarctica

NASA’s Scientific Balloon Program has returned to Antarctica’s icy expanse to kick off the annual Antarctic Long-Duration Balloon Campaign, where two balloon flights will carry a total of nine missions to near space. Launch operations will begin mid-December from the agency’s Long Duration Balloon camp located near the U.S. National Science Foundation’s McMurdo Station on the Ross Ice Shelf.

“Antarctica is our cornerstone location for long-duration balloon missions, and we always look forward to heading back to ‘the ice,’” said Andrew Hamilton, acting chief of NASA’s Balloon Program Office at the agency’s Wallops Flight Facility in Virginia. “It’s a tremendous effort to stage a campaign like this in such a remote location, and we are grateful for the support provided to us by the U.S. National Science Foundation, New Zealand, and the U.S. Air Force.”

This year’s Antarctic campaign includes investigations in astrophysics, space biology, heliospheric research, and upper atmospheric research, along with technology demonstrations. The campaign’s two primary missions include:

• GAPS (General Anti-Particle Spectrometer), led by Columbia University in New York, is an experiment to detect anti-matter particles produced by dark matter interactions. The anti-particles stemming from these interactions in our galaxy can only be observed from a suborbital platform or in space, since Earth’s atmosphere shields us from the cosmic radiation. GAPS aims to provide an unprecedented level of sensitivity to certain classes of anti-particles, allowing the exploration of a currently unexplored energy regime of the elusive dark matter.

• Salter Test Flight Universal, led by NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, will test and validate long-duration balloon and subsystems, while supporting several piggyback missions on the flight.

Piggyback missions, or smaller payloads, riding along with the Salter Test Flight Universal mission include:

• MARSBOx (Microbes in Atmosphere for Radiation, Survival, and Biological Outcomes Experiments), led by the U.S. Naval Research Laboratory, will expose melanized fungus, called Aspergillus niger, to the stratosphere’s extreme radiation and temperature fluctuations, low atmospheric pressure, and absence of water — conditions much like the surface of Mars. Knowledge of how this fungus adapts to protect itself in this harsh environment could lead to the development of treatments to protect astronauts from high radiation exposure.

• EMIDSS-6 (Experimental Module for Iterative Design of Satellite Subsystems 6), led by National Polytechnical Institute − Mexico, is a technological platform with experimental design and operational validation of instrumentation that will collect and store data from the stratospheric environment to contribute to the study of climate change.

• SPARROW-6 (Sensor Package for Attitude, Rotation, and Relative Observable Winds – 6), led by NASA’s Balloon Program Office at NASA Wallops, will demonstrate relative wind measurements using an ultrasonic anemometer designed for the balloon float environment.  

• WALRUSS (Wallops Atmospheric Light Radiation and Ultraviolet Spectrum Sensor), led by the Balloon Program Office at NASA Wallops, is a technology demonstration of a sensor package capable of measuring the total ultraviolet wavelength spectrum and ozone concentration.

• INDIGO (INterim Dynamics Instrumentation for Gondolas), led by the Balloon Program Office at NASA Wallops, is a data recorder meant to measure the shock, rotation, and attitude of the gondola during the launch, float, and landing phases of flight. Data will be used to improve understanding of the dynamics of flight and to inform the design of future components and hardware.

The remaining two piggyback missions are led by finalists of NASA’s FLOATing DRAGON (Formulate, Lift, Observe, And Testing; Data Recovery And Guided On-board Node) Balloon Challenge, sponsored by the Balloon Program Office at NASA Wallops and managed by the National Institute of Aerospace. The challenge was created for student teams to design, build, and fly an autonomous aerial vehicle, deployed from a gondola during a high-altitude balloon flight. The teams’ student-built data vaults will be safely dropped from around 120,000 feet with the capability to target a specific landing point on the ground to manage risk. The missions participating in the Antarctic campaign are Purdue University’s Purdue DRAGONfly, and University of Notre Dame’s IRIS v3.

NASA’s zero-pressure balloons, used in the Antarctic campaign, are made of a thin plastic film and are capable of lifting up to 8,000 pounds of payload and equipment to altitudes above 99.8% of Earth’s atmosphere. Zero-pressure balloons, which typically have a shorter flight duration from the loss of gas during the day-to-night cycle, can support long-duration missions in polar regions during summer. The constant daylight of Antarctica’s austral summer and stable stratospheric wind conditions allow the balloon missions to remain in near space for days to weeks, gathering large amounts of scientific data as they circle the continent.

NASA’s Wallops Flight Facility in Virginia manages the agency’s scientific balloon flight program with 10 to 15 flights each year from launch sites worldwide. Peraton, which operates NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, provides mission planning, engineering services, and field operations for NASA’s scientific balloon program. The Columbia team has launched more than 1,700 scientific balloons over some 40 years of operations. NASA’s balloons are fabricated by Aerostar. The NASA Scientific Balloon Program is funded by the NASA Headquarters Science Mission Directorate Astrophysics Division. NASA balloon launch operations from Antarctica receive logistical support from the U.S. National Science Foundation’s Office of Polar Programs, which oversees the U.S. Antarctic Program.

NASA to Discuss Firefly’s First Robotic Artemis Moon Flight

NASA will host a media teleconference at 1 p.m. EST Tuesday, Dec. 17, to discuss the agency science and technology flying aboard Firefly Aerospace’s first delivery to the Moon as part of the NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. 

Audio of the call will livestream on the agency’s website at:

https://www.nasa.gov/live

Briefing participants include:

• Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters
• Ryan Watkins, program scientist, Exploration Science Strategy and Integration Office, NASA Headquarters
• Jason Kim, chief executive officer, Firefly Aerospace

To participate by telephone, media must RSVP no later than two hours before the briefing to: ksc-newsroom@mail.nasa.gov.

Firefly’s Blue Ghost lunar lander will launch on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The six-day launch window opens no earlier than mid-January 2025.

The lunar mission, named Ghost Riders in the Sky, will land near a volcanic feature called Mons Latreille within Mare Crisium, a more than 300-mile-wide basin located in the northeast quadrant of the Moon’s near side. The mission will carry 10 NASA instruments and first-of-their-kind demonstrations to further our understanding of the Moon’s environment and help prepare for future human missions to the lunar surface, as part of the agency’s Moon to Mars exploration approach.  
Science investigations on this flight include testing lunar subsurface drilling, regolith sample collection, global navigation satellite system abilities, radiation tolerant computing, and lunar dust mitigation. The data captured could also benefit humans on Earth by providing insights into how space weather and other cosmic forces impact Earth.

Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA is to be one of many customers on future flights.

Scientists Share Early Results from NASA’s Solar Eclipse Experiments

Scientists Share Early Results from NASA’s Solar Eclipse Experiments 

On April 8, 2024, a total solar eclipse swept across North America, from the western shores of Mexico, through the United States, and into northeastern Canada. For the eclipse, NASA helped fund numerous research projects and called upon citizen scientists in support of NASA’s goal to understand how our home planet is affected by the Sun – including, for example, how our star interacts with Earth’s atmosphere and affects radio communications.  

At a press briefing on Tuesday, Dec. 10, scientists attending the annual meeting of the American Geophysical Union in Washington, D.C., reported some early results from a few of these eclipse experiments. 

“Scientists and tens of thousands of volunteer observers were stationed throughout the Moon’s shadow,” said Kelly Korreck, eclipse program manager at NASA Headquarters in Washington. “Their efforts were a crucial part of the Heliophysics Big Year – helping us to learn more about the Sun and how it affects Earth’s atmosphere when our star’s light temporarily disappears from view.”

Changes in the Corona

On April 8, the Citizen CATE 2024 (Continental-America Telescopic Eclipse) project stationed 35 observing teams from local communities from Texas to Maine to capture images of the Sun’s outer atmosphere, or corona, during totality. Their goal is to see how the corona changed as totality swept across the continent.

On Dec. 10, Sarah Kovac, the CATE project manager at the Southwest Research Institute in Boulder, Colorado, reported that, while a few teams were stymied by clouds, most observed totality successfully — collecting over 47,000 images in all. 

These images were taken in polarized light, or light oriented in different directions, to help scientists better understand the processes that shape the corona.

Kovac shared the first cut of a movie created from these images. The project is still stitching together all the images into the final, hour-long movie, for release at a later time. 

“The beauty of CATE 2024 is that we blend cutting-edge professional science with community participants from all walks of life,” Kovac said. “The dedication of every participant made this project possible.” 

Meanwhile, 50,000 feet above the ground, two NASA WB-57 aircraft chased the eclipse shadow as it raced across the continent, observing above the clouds and extending their time in totality to approximately 6 minutes and 20 seconds. 

On board were cameras and spectrometers (instruments that analyze different wavelengths of light) built by multiple research teams to study the corona. 

On Dec. 10, Shadia Habbal of the University of Hawaii, who led one of the teams, reported that their instruments collected valuable data, despite one challenge. Cameras they had mounted on the aircraft’s wings experienced unexpected vibrations, which caused some of the images to be slightly blurred.

However, all the cameras captured detailed images of the corona, and the spectrometers, which were located in the nose of the aircraft, were not affected. The results were so successful, scientists are already planning to fly similar experiments on the aircraft again.

“The WB-57 is a remarkable platform for eclipse observations that we will try to capitalize on for future eclipses,” Habbal said. 

Affecting the Atmosphere

On April 8, amateur or “ham” radio operators sent and received signals to one another before, during, and after the eclipse as part of the Ham Radio Science Citizen Investigation (HamSCI) Festivals of Eclipse Ionospheric Science. More than 6,350 amateur radio operators generated over 52 million data points to observe how the sudden loss of sunlight during totality affects their radio signals and the ionosphere, an electrified region of Earth’s upper atmosphere. 

Radio communications inside and outside the path of totality improved at some frequencies (from 1-7 MHz), showing there was a reduction in ionospheric absorption. At higher frequencies (10 MHz and above), communications worsened. 

Results using another technique, which bounced high-frequency radio waves (3-30 MHz) off the ionosphere, suggests that the ionosphere ascended in altitude during the eclipse and then descended to its normal height afterward. 

“The project brings ham radio operators into the science community,” said Nathaniel Frissell, a professor at the University of Scranton in Pennsylvania and lead of HamSCI. “Their dedication to their craft made this research possible.”  

Also looking at the atmosphere, the Nationwide Eclipse Ballooning Project organized student groups across the U.S. to launch balloons into the shadow of the Moon as it crossed the country in April 2024 and during a solar eclipse in October 2023. Teams flew weather sensors and other instruments to study the atmospheric response to the cold, dark shadow. 

This research, conducted by over 800 students, confirmed that eclipses can generate ripples in Earth’s atmosphere called atmospheric gravity waves. Just as waves form in a lake when water is disturbed, these waves also form in the atmosphere when air is disturbed. This project, led by Angela Des Jardins of Montana State University in Bozeman, also confirmed the presence of these waves during previous solar eclipses. Scientists think the trigger for these waves is a “hiccup” in the tropopause, a layer in Earth’s atmosphere, similar to an atmospheric effect that is observed during sunset. 

“Half of the teams had little to no experience ballooning before the project,” said Jie Gong, a team science expert and atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But their hard work and research was vital in this finding.”

NASA TechLeap Prize: Space Technology Payload Challenge

The Space Technology Payload Challenge invites individuals, teams, and organizations to submit applications for systems that advance technology to address one or more of NASA’s shortfalls. These shortfalls identify technology areas where further technology development is required to meet future exploration, science, and other mission needs. In addition, technologies to address these select shortfalls are also potentially well suited for a suborbital or hosted orbital flight demonstration to help mature the innovation. The expectation is that the technology will be tested at the end of the challenge aboard a suborbital vehicle, rocket-powered lander, high altitude balloon, aircraft following a reduced gravity profile (i.e., parabolic flight), or orbital vehicle that can host payloads. The shortfalls selected for this challenge are divided into two groups. The first group is derived from the Space Technology Mission Directorate (STMD) civil space shortfall list. The second group is in partnership with NASA’s Biological and Physical Sciences (BPS) Division and is derived from the Commercially Enabled Rapid Space Science Initiative (CERISS) program needs. 

Award: $4,500,000 in total prizes

Open Date: December 10, 2024
