Extended Temporary Duty (ETDY)

Reduced Per Diem rate

NASA’s standard reduced per diem rate for ETDY travel is 65 percent under the current policy as defined in the NASA Procedural Requirements (NPR) 9750.1-3.1.2.

     a.   Consistent with 41 CFR 301-11.200, an ETDY authorization can include reasonable further reductions from this standard rate or limitations on approved lodging for unique circumstances, to the extent it can be  determined in advance that such will substantially lower costs without mission impact.  For example, if lodging is obtained at 50 percent per diem, the ETDY authorization should be adjusted to authorize a lower rate. 

    b.   The reduced rate of reimbursement begins on the first day of travel regardless of the mode of transportation, except as noted in 3.1.3.  Allowances are covered by the reduced per diem rate; therefore, NASA will authorize the employee a per diem rate (up to 65 percent) to reasonably cover expenses for a one bedroom furnished apartment.  For ETDY greater than 90 days, first consideration should be given to long-term lodging facilities.  Long-term lodging facilities are available on the GSA schedule at http://www.gsa.gov.  If a long-term facility is not selected, proper justification should be provided.

NASA’s Webb Reveals Dynamic Panorama of Star Formation

A star-forming region. The left two thirds of the image is blanketed in thick clouds of green and yellow gas and dust that form swirling patterns. Some of the gas is spread into thin, thready wisps. The right third of the image is the black background speckled with stars and multi-colored dots that represent distant galaxies. Bright stars are scattered throughout the clouds, with the densest cluster situated in the center of the scene. Each is crowned with six long spikes and two shorter spikes created by the optics of the telescope’s mirrors. In the upper right, a couple of hidden stars blast out long, glowing jets of material that glow in blue.

NASA’s James Webb Space Telescope recently observed IC 348, a star-forming region just 1,000 light-years away from Earth. Webb’s sharp vision revealed tiny brown dwarfs, some just twice Jupiter’s mass, and young stars ejecting powerful jets crashing into surrounding gas and dust.

This starry view of the nearby star-forming region IC 348 is one of the largest images released to date from NASA’s James Webb Space Telescope. Using Webb, astronomers searched IC 348 for brown dwarfs, which are less massive than the smallest stars. The researchers discovered brown dwarfs just twice the mass of Jupiter, bringing the study of these curious objects into a new mass range and revealing new insights about the star formation process.

The star-forming region IC 348 is located just 1,000 light-years away in the constellation Perseus. In regions like IC 348, cold clouds of molecular hydrogen gas collapse to form new stars, creating glowing, sculpted scenes like this one. The star-formation process can create widely varied objects, from massive stars that expire after only a few million years in core-collapse supernova explosions to the smallest and most common stars, which are long lived and produce powerful stellar storms.

The smallest stars weigh in at around 8 percent of the Sun’s mass. Below this mass lies a strange class of objects called brown dwarfs. Brown dwarfs form in the same way stars do, through the collapse of molecular clouds. However, unlike stars, the cores of brown dwarfs never become hot enough to fuse ordinary hydrogen into helium (though many briefly fuse deuterium, or heavy hydrogen, early in their lives).

What’s still not clear, and what researchers hoped to learn by using Webb’s sensitive instruments to study IC 348, is how small the smallest objects created by the star-formation process are. In other words, how small is the smallest brown dwarf?

Researchers seeking to answer this question first used Webb to study IC 348 in 2022, when they discovered brown dwarfs with masses as low as three to four times the mass of Jupiter. Now, the same research team has used Webb to probe even deeper into this region in search of even smaller brown dwarfs. 

The team used Webb’s NIRCam (Near-Infrared Camera) in 2024 to capture the warm glow of young brown dwarfs and newborn stars seen in this new image of IC 348. After selecting candidate brown dwarfs based on their colors and brightness, they followed up with Webb’s NIRSpec (Near-Infrared Spectrograph) in 2025 to conduct spectroscopic observations to study the masses of the brown dwarfs.

These deep Webb observations revealed something remarkable to the researchers: brown dwarfs with masses as low as just twice the mass of Jupiter or only 0.19 percent of the Sun’s mass — far smaller than theory predicts brown dwarfs should be. These are the least massive brown dwarfs known and their existence poses a challenge to models of how stars form.

In addition to the discovery of these unexpectedly lightweight brown dwarfs, the Webb observations contained even more surprises. One of the lightest newfound brown dwarfs showed signs of a disk, suggesting that small planets could be forming around an object that is itself only the mass of a planet.

While inspecting the spectra of IC 348’s brown dwarfs, the research team also found a feature they attributed to an unidentified hydrocarbon — molecules made only of hydrogen and carbon atoms. This specific feature has only been seen in the atmospheres of the lowest-mass brown dwarfs, suggesting that these extreme objects might exist in a spectral class of their own.

The stars and brown dwarfs of IC 348 aren’t the only attractions in this image. A brilliantly detailed collection of protostars occupies the upper right corner. Several of these protostars are accompanied by Herbig-Haro objects, which are luminous regions that form when jets from growing newborn stars crash into the gas and dust around the star.

The long, narrow feature that is oriented horizontally in this corner is the Herbig-Haro object HH 797. Upon close inspection, this source is revealed to be two protostars with nearly parallel outflows. Just to the right of HH 797 is the propeller-shaped source HH 211, which features both narrow jets and broader outflows.

IC 348 Collage

A collage, with three large panels along the top and four smaller ones on the bottom. The middle panel on top shows star-forming region IC 348, which has a blanket of thick clouds of yellow and green dust blanketing most of the image. Six boxes are drawn around features in the region, numbered 1–6. The other six panels are numbered and show these features enlarged. They include bright stars throughout the nebula, protostars shooting jets of gas, a distant spiral galaxy, and a gravitational lens.
This collage features a collection of insets from NASA’s James Webb Space Telescope’s image of star-forming region IC 348: embedded stars, a central star cluster, faint outflows, Herbig-Haro objects, gravitational lensing, and spiral galaxies.

The data used to create this image comes from the Webb General Observer Program 4866. In addition to studying the lowest-mass objects created through the star-formation process, this program also seeks to understand how the populations of planetary-mass objects like brown dwarfs vary between star-forming regions, as well as the origins of the hydrocarbon feature in the lowest-mass brown dwarfs.

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 CSA (Canadian Space Agency).

New Crops, Health Research Proposals to Help NASA Advance Exploration

NASA has selected 12 new investigations to help support human explorers in space. Six will help advance the ability to produce food off-planet, while another six advance the understanding of how unique conditions associated with space exploration can impact the health and physiology of astronauts.  

The six food-focused investigations, supported by the agency’s Space Crops grants, advance NASA’s goal of harnessing the power of plants to enhance quality of life for humans in space, as well as to enable lunar and Mars exploration. Four of the space crops proposals focus on studies of edible plants and how their growth, physiology, and associated microbial communities are affected by environmental conditions in space or on other planetary bodies.

Another proposal involves understanding mechanisms by which certain plant species, called resurrection plants, can withstand extreme, dry conditions. The last space crops proposal builds on previous studies on the International Space Station to uncover functions of algal genes, segments of DNA controlling algae survival, whose expression is modified by spaceflight. Such studies can help scientists integrate biological-based solutions into space life-support systems.

The second set of six proposals fall under the agency’s Biological and Physical Sciences Division’s focus on precision health, which seeks to unravel the mechanisms by which space exploration affects health and well-being. One proposal studies how lunar dust exposure impacts respiratory, immune, and inflammation responses.  A second proposal identifies repurposed drugs that can mitigate the effects space travel has on health and physiology.

Two more of the research proposals look at how radiation combined with other stressors affects age-relevant characteristics seen in various organ and physiological systems. The final two proposals assess molecular and cellular changes induced by stressors in space that can alter gene expression or protein function. The research will identify ways to mitigate health issues and develop early-warning detection systems to notify crew of potential concerns.

The principal investigators who conduct the space biology studies come from 10 institutions across eight states. Nine of the awards are for investigators who are receiving funding from the Space Biology Program for the first time.

APOD: 2026 September 14 – Where Your Elements Came From

APOD

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

A table with each entry being a separate element. The entries depict where each element comes from (i.e., the big bang, stellar deaths, etc).

Where Your Elements Came From

Explanation: The hydrogen in your body and present in every molecule of water came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts or gravitational wave events. Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life. The featured periodic table is color coded to indicate humanity‘s best guess as to the nuclear origin of all known elements. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.

Summer Training: Catching Up With NASA’s Astronaut Candidates

NASA/Helen Arase Vargas

Did you spend part of your summer camping, hiking, at the pool, or in an aircraft? So did NASA’s 2025 Astronaut Candidate Class.

The 10 candidates have been working their way through a comprehensive and rigorous training program since the agency introduced them to the public on Sept. 22, 2025, from NASA’s Johnson Space Center in Houston. They are approximately halfway through the nearly two-year training program, which will equip them for missions to low Earth orbit, the Moon, and ultimately, Mars.

Geology Studies

Since the astronaut candidates can one day be assigned to a future Artemis mission to the lunar surface, geology courses are an important part of their training. In May, candidates completed classroom trainings at Johnson before venturing to the Rio Grande del Norte National Monument in New Mexico for additional classroom instruction and training in the field. Several candidates also joined NASA astronauts and Artemis mission support teams for geology field training in Iceland in July. They practiced geologic observations, sampling with tools, navigation, and teamwork, all skills and processes that translate directly to Artemis lunar missions.

Flight Training

Whether learning to become a pilot or sharpening their existing piloting skills, astronaut candidates train in aircraft to build confidence, coordination, adaptability, and resilience in high-stakes environments. This summer, that training included flights on NASA’s WB-57s – a trio of long-range, high-altitude airplanes that have flown research missions since the 1960s. The class also began flying NASA’s T-38 supersonic jets.

Altitude Chamber Runs

Candidates have also spent time in one of Johnson’s altitude chambers as part of their flight training. These unique facilities allow NASA to simulate physical pressure levels ranging from those at sea level to near vacuum. After donning flight suits and helmets, candidates enter the chamber to familiarize themselves with the conditions they will face on high-altitude flights and in space, and to practice different protocols and interventions designed to keep them safe.

Water Survival Training

Candidates continued survival training to prepare for the unlikely event of landing in remote environments after a mission. Water survival exercises in Johnson’s Neutral Buoyancy Laboratory, or NBL, simulate these scenarios while also building teamwork and decision-making skills.

On top of these exercises, candidates are completing intensive Russian language classes and cross-cultural training to prepare for missions spanning countries and continents. They are learning to operate spacecraft systems used in human spaceflight missions, conducting spacewalk training at the NBL, and training inside other mockups of space vehicles. They are also learning emergency procedures, maintenance, and repair of spacecraft.

The class is on track to graduate in 2027, when they will join NASA’s active astronaut corps and await their first flight assignments. Whether they go on to contribute to research taking place aboard the International Space Station or venture to the Moon to prepare for future Mars missions, the graduates will have the operational expertise, scientific knowledge, and technical background necessary to advance NASA’s deep space exploration goals and sustain a long-term human presence beyond low Earth orbit.
