NASA researchers are looking at the possibility of using a wingless, unpowered aircraft design from the 1960s to gather atmospheric data on other planets – doing the same work as small satellites but potentially better and more economically.

John Bodylski, a principal investigator at NASA’s Armstrong Flight Research Center in Edwards, California, hypothesized a lifting body aircraft design NASA tested decades ago could meet the requirements for an atmospheric probe that can collect measurements of giant planets, like Uranus. The design relies on the aircraft’s shape for lift, rather than wings.

Three aircraft are in a row on a dry lakebed.

Bodylski submitted his idea and earned a NASA Armstrong Center Innovation Fund award to write a technical paper explaining the concept and design. The award also supports construction of models to help people conceptualize his atmospheric probe. Enter the NASA Armstrong Dale Reed Subscale Flight Research Laboratory.

Robert “Red” Jensen and Justin Hall, two of the lab’s designers, technicians, and pilots, brought Bodylski’s designs to life. Jensen and Hall created a mold, then layered in carbon-fiber and foam that cured for eight hours under vacuum. The parts were removed from the molds, refined, and later joined together.

Another few layers will be added and then it will be cured about eight hours under vacuum.

The first of the two lifting body aircraft, both of which are 27 1/2 inches long, and 24 inches wide, is complete and offers a first look at the concept. The second aircraft is almost ready and includes hinged flight control surfaces. Flight controls systems connected to those surfaces will be mounted inside the structure before the model’s final assembly.

Together, the two models can test Bodylski’s ideas and provide flight data for creating better computer models. In the future, those computer models could help researchers built atmospheric probes based on those designs. Bodylski’s concept called for sending the aircraft on missions attached to satellites. Once in the orbit of a planet, the probe aircraft – about the same size as the models – would separate from the satellite through pyrotechnic bolts, deploying in the atmosphere to collect data for study.

Two men take a major section of an aircraft model out of a mold.

Current atmospheric probes, small satellites known as CubeSats, gather and transmit data for about 40 minutes and can take in approximately 10 data points before their parent satellite is out of range. Bodylski’s design could descend more rapidly and at a steeper angle, collecting the same information in 10 minutes, plus additional data for another 30 minutes from much deeper in a thick atmosphere.

Following a series of technical briefings and flight readiness reviews, the aircraft is expected to fly in March 2024. It will fly as a glider air-launched from a cradle attached to rotorcraft often used by the lab. Future tests could include powered flight depending on what data researchers determine they need.

“We are looking to take an idea to flight and show that a lifting body aircraft can fly as a probe at this scale – that it can be stable, that components can be integrated into the probe, and that the aircraft can achieve some amount of lift,” Bodylski said.

Evolved Adapter for Future NASA SLS Flights Readied for Testing

Evolved Adapter for Future NASA SLS Flights Readied for Testing

A test version of the universal stage adapter for the SLS (Space Launch System) rocket for Artemis 4 is seen inside Marshall Space Flight Center’s facility in Huntsville, Alabama. The adapter sits on a yellow piece of hardware. There is an American flag hanging on the wall to the right and the word “Leidos” is painted black on the white adapter.

A test version of the universal stage adapter for NASA’s more powerful version of its SLS (Space Launch System) rocket arrived to Building 4619 at NASA’s Marshall Space Flight Center in Huntsville, Alabama, Feb. 22 from Leidos in Decatur, Alabama. The universal stage adapter will connect the rocket’s upgraded in-space propulsion stage, called the exploration upper stage, to NASA’s Orion spacecraft as part of the evolved Block 1B configuration of the SLS rocket. It will also serve as a compartment capable of accommodating large payloads, such as modules or other exploration spacecraft. The SLS Block 1B variant will debut on Artemis IV and will increase SLS’s payload capability to send more than 84,000 pounds to the Moon in a single launch.

In Building 4619’s Load Test Annex High Bay at Marshall, the development test article will first undergo modal testing that will shake the hardware to validate dynamic models. Later, during ultimate load testing, force will be applied vertically and to the sides of the hardware. Unlike the flight hardware, the development test article has flaws intentionally included in its design, which will help engineers verify that the adapter can withstand the extreme forces it will face during launch and flight. The test article joins an already-rich history of rocket hardware that has undergone high-and-low pressure, acoustic, and extreme temperature testing in the multipurpose, high-bay test facility; it will be tested in the same location that once bent, compressed, and torqued the core stage intertank test article for SLS rocket’s Block 1 configuration. Leidos, the prime contractor for the universal stage adapter, manufactured the full-scale prototype at its Aerospace Structures Complex in Decatur.

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft and Gateway in orbit around the Moon and commercial human landing systems, next-generational spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

NASA-Supported Team Discovers Aurora-Like Radio Bursts Above Sunspot

NASA-Supported Team Discovers Aurora-Like Radio Bursts Above Sunspot

A NASA-funded team of scientists has discovered long-lasting radio signals emanating from the Sun that are similar to those associated with auroras – northern and southern lights – on Earth.

Detected about 25,000 miles (40,000 km) above a sunspot – a relatively cool, dark, and magnetically active region on the Sun – such radio bursts had previously been observed only on planets and other stars.

“This sunspot radio emission represents the first detection of its kind,” said Sijie Yu of the New Jersey Institute of Technology, Newark, who is the lead author of a paper reporting the discovery in the January 2024 issue of Nature Astronomy. The research was first published online in November 2023.

In this illustration, a small portion of the Sun appears in yellow at the bottom with a dark sunspot in the center. Above the sunspot, against a black background, appear several vertical, curved streaks of light that are light pink at the bottom, closest to the sunspot and darken to dark pink in the middle then purple at the top. The streaks also appear thinner at the top than at the bottom.
Scientists have discovered radio bursts above a sunspot that resemble radio emissions from auroras on Earth. The pink-purple streaks in this illustration represent the radio emissions, with higher-frequency radio signals in pink, closer to the sunspot, and lower frequencies in purple. The thin lines represent magnetic field lines above the sunspot. The sunspot is the dark region on the Sun at the bottom.
Sijie Yu, New Jersey Institute of Technology

The discovery could help us better understand our own star as well as the behavior of distant stars that produce similar radio emissions.

The Sun often emits short radio bursts that last for minutes or hours. But the radio bursts Yu’s team detected, using the Karl G. Jansky Very Large Array in New Mexico, persisted for over a week.

These sunspot radio bursts also have other characteristics – such as their spectra (or intensity at different wavelengths) and their polarization (the angle or direction of the radio waves) – that are much more like radio emissions produced in the polar regions of Earth and other planets with auroras.

On Earth (and other planets such as Jupiter and Saturn), auroras shimmer in the night sky when solar particles are caught up in the planet’s magnetic field and get pulled toward the poles, where magnetic field lines converge. As they accelerate poleward, the particles generate intense radio emissions at frequencies around a few hundred kilohertz and then smash into atoms in the atmosphere, causing them to emit light as auroras.

The analysis by Yu’s team suggests the radio bursts above the sunspot are likely produced in a comparable way – when energetic electrons get trapped and accelerated by converging magnetic fields above a sunspot. Unlike Earth’s auroras, though, the radio bursts from sunspots occur at much higher frequencies – hundreds of thousands of kilohertz to roughly 1 million kilohertz. “That’s a direct result of the sunspot’s magnetic field being thousands of times stronger than Earth’s,” Yu said.

An image shows the Sun as an orange disk. In the upper left is a large sunspot with a few smaller sunspots to the left and right of it.

Similar radio emissions have previously been observed from some types of low-mass stars as well. This discovery introduces the possibility that aurora-like radio emissions may originate from large spots on those stars (called “starspots”) in addition to the previously proposed auroras in their polar regions.

“The discovery excites us as it challenges existing notions of solar radio phenomena and opens new avenues for exploring magnetic activities both in our Sun and in distant stellar systems,” Yu said.

“NASA’s growing heliophysics fleet is well suited to continue to investigate the source regions of these radio bursts,” said Natchimuthuk Gopalswamy, a heliophysicist and solar radio researcher at NASA’s Goddard Space Flight Center. “For example, the Solar Dynamics Observatory continually monitors the Sun’s active regions, which likely give rise to this phenomenon.”

In the meantime, Yu’s team plans to reexamine other solar radio bursts to see whether any appear to be similar to the aurora-like radio bursts they found. “We aim to determine if some of the previously recorded solar bursts could be instances of this newly identified emission,” Yu said.

The research by Yu’s team has been supported in part by a NASA Early Career Investigator Program (ECIP) grant awarded to the New Jersey Institute of Technology.

What do margaritas, vinegar, and ant stings have in common? They contain chemical ingredients that NASA’s James Webb Space Telescope has identified surrounding two young protostars known as IRAS 2A and IRAS 23385. Although planets are not yet forming around those stars, these and other molecules detected there by Webb represent key ingredients for making potentially habitable worlds.

An international team of astronomers used Webb’s MIRI (Mid-Infrared Instrument) to identify a variety of icy compounds made up of complex organic molecules like ethanol (alcohol) and likely acetic acid (an ingredient in vinegar). This work builds on previous Webb detections of diverse ices in a cold, dark molecular cloud.

The orange cloud is dense and bright close to the top of the image, like rolling clouds, and grows darker and more wispy toward the bottom and in the top corner. One bright star with six short diffraction spikes and several dimmer stars are visible as light spots among the clouds.
This image at a wavelength of 15 microns was taken by MIRI (the Mid-Infrared Instrument) on NASA’s James Webb Space Telescope, of a region near the protostar known as IRAS 23385. IRAS 23385 and IRAS 2A (not visible in this image) were targets for a recent research effort by an international team of astronomers that used Webb to discover that the key ingredients for making potentially habitable worlds are present in early-stage protostars, where planets have not yet formed.

What is the origin of complex organic molecules (COMs) ?

“This finding contributes to one of the long-standing questions in astrochemistry,” said team leader Will Rocha of Leiden University in the Netherlands. “What is the origin of complex organic molecules, or COMs, in space? Are they made in the gas phase or in ices? The detection of COMs in ices suggests that solid-phase chemical reactions on the surfaces of cold dust grains can build complex kinds of molecules.”

As several COMs, including those detected in the solid phase in this research, were previously detected in the warm gas phase, it is now believed that they originate from the sublimation of ices. Sublimation is to change directly from a solid to a gas without becoming a liquid. Therefore, detecting COMs in ices makes astronomers hopeful about improved understanding of the origins of other, even larger molecules in space.

Scientists are also keen to explore to what extent these COMs are transported to planets at much later stages of protostellar evolution. COMs in cold ices are thought to be easier to transport from molecular clouds to planet-forming disks than warm, gaseous molecules. These icy COMs can therefore be incorporated into comets and asteroids, which in turn may collide with forming planets, delivering the ingredients for life to possibly flourish.

The science team also detected simpler molecules, including formic acid (which causes the burning sensation of an ant sting), methane, formaldehyde, and sulfur dioxide. Research suggests that sulfur-containing compounds like sulfur dioxide played an important role in driving metabolic reactions on the primitive Earth.

The x-axis ranges from 6.8 microns on the left to 8.6 microns on the right, labeled in even increments of 0.2 microns. The y-axis ranges from 0 on the top to about 0.65 on the bottom, with labeled tick marks at 0.2, 0.4, and 0.6. A jagged white line with several prominent valleys extends horizontally. Vertical bands in different colors mark different wavelength regions and are labeled with molecular names and formulas.

These molecules, which are key ingredients for making potentially habitable worlds, include ethanol, formic acid, methane, and likely acetic acid, in the solid phase. The finding came from the study of two protostars, IRAS 2A and IRAS 23385, both of which are so young that they are not yet forming planets.

Similar to the early stages of our own solar system?

Of particular interest is that one of the sources investigated, IRAS 2A, is characterized as a low-mass protostar. IRAS 2A may therefore be similar to the early stages of our own solar system. As such, the chemicals identified around this protostar were likely present in the first stages of development of our solar system and later delivered to the primitive Earth.

“All of these molecules can become part of comets and asteroids and eventually new planetary systems when the icy material is transported inward to the planet-forming disk as the protostellar system evolves,” said Ewine van Dishoeck of Leiden University, one of the coordinators of the science program. “We look forward to following this astrochemical trail step-by-step with more Webb data in the coming years.”

These observations were made for the JOYS+ (James Webb Observations of Young ProtoStars) program. The team dedicated these results to team member Harold Linnartz, who unexpectedly passed away in December 2023, shortly after the acceptance of this paper.

This research has been accepted for publication in the journal Astronomy & Astrophysics.

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.
