A salute is widely recognized as a display of respect, but did you know it also means ‘hello’ in American Sign Language?
It is one of the signs that Jesse Bazley, International Space Station/Commercial Low Earth Orbit Development Program integration team lead, subtly incorporates into his daily interactions with colleagues at NASA’s Johnson Space Center in Houston.
In May 2021, Jesse Bazley worked his final shift as an Environmental and Thermal Operating Systems flight controller in the Mission Control Center at NASA’s Johnson Space Center in Houston. Image courtesy of Jesse Bazley Bazley is hard of hearing, which has at times presented challenges in his daily work – particularly during his stint as an Environmental and Thermal Operating Systems flight controller for the space station. “Working on console [in the Mission Control Center], you must listen to dozens of voice loops at a time, sometimes in different languages,” he said, adding that the standard-issue headset for flight controllers was not compatible with his hearing aids. Bazley adapted by obtaining a headset that fit over his hearing aids, learning how to adjust the audio system’s volume, and limiting over-the-air discussions when possible.
Bazley has been part of the NASA team for 17 years, filling a variety of roles that support the International Space Station. One of his proudest achievements occurred early in his tenure. Bazley was an intern at Marshall Space Flight Center in Huntsville, Alabama, in 2006 when the space station’s Water Recovery System was being tested. The system converts the station’s wastewater into drinkable water for the crew. When he arrived at Johnson one year later, his first assignment was to assist with the system’s procedure and display development for its incorporation into the space station’s core operations. “Now, 16 years later, it is commonplace for the space station to ‘turn yesterday’s coffee into tomorrow’s coffee’,” he said.
Jesse Bazley supporting the Atmosphere and Consumables Engineer console during the STS-127 mission in July 2009. NASA His favorite project so far has been integrating the station’s Thermal Amine Scrubber – which removes carbon dioxide from the air – into station operations. “I worked it from the beginning of NASA’s involvement, helping the provider with software testing and the integration of a brand-new Mission Control Center communications architecture,” he said.
Today, Bazley works to integrate subject matter experts from Johnson’s Flight Operations Directorate (FOD) into the processes of the International Space Station and Commercial Low Earth Orbit Development Programs. “I help pull together FOD positions on topics and coordinate reviews of provider materials to ensure that the operations perspective is maintained as development moves forward,” he explained.
While Bazley no longer supports a console, he must continue adapting to difficult hearing environments. He uses the captioning tools available through videoconferencing software during frequent team meetings, for example. “It’s important to understand that people have visible and invisible disabilities,” he said. “Sometimes their request for a remote option is not because they want to avoid an in-person meeting. It may be that they work best using the features available in that virtual environment.”
Bazley also chairs the No Boundaries Employee Resource Group, which promotes the development, inclusion, and innovation of Johnson’s workforce with a focus on employees with disabilities and employees who are caregivers of family members with disabilities.
From these diverse roles and experiences, Bazley has learned to listen to his gut instincts. “In flight operations, you must work with short timelines when things happen in-orbit, so you have to trust your training,” he said. “Understanding when you have enough information to proceed is critical to getting things done.”
Bazley looks forward to the further commercialization of low Earth orbit so NASA can focus resources on journeying to the Moon and Mars. “Aviation started out as government-funded and now is commonplace for the public. I look forward to seeing how that evolution progresses in low Earth orbit.”
His advice to the Artemis Generation is to consider the long-term impact of their actions and decisions. “What looks great on paper may not be a great solution when you have to send 10 commands just to do one task, or when the crew has to put their hand deep into the spacecraft to actuate a manual override,” he said. “The decisions you make today will be felt by operations in the future.”

Video: 00:01:20 Approximately 41 000 years ago, Earth’s magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth’s magnetic field weakened significantly—dropping to a minimum of 5% of its current strength—which allowed more cosmic rays to reach Earth’s atmosphere.
Scientists at the Technical University of Denmark and the German Research Centre for Geosciences used data from ESA’s Swarm mission, along with other sources, to create a sounded visualisation of the Laschamp event. They mapped the movement of Earth’s magnetic field lines during the event and created a stereo sound version which is what you can hear in the video.
The soundscape was made using recordings of natural noises like wood creaking and rocks falling, blending them into familiar and strange, almost alien-like, sounds. The process of transforming the sounds with data is similar to composing music from a score.
Data from ESA’s Swarm constellation are being used to better understand how Earth’s magnetic field is generated. The satellites measure magnetic signals not only from the core, but also from the mantle, crust, oceans and up to the ionosphere and magnetosphere. These data are crucial for studying phenomena such as geomagnetic reversals and Earth’s internal dynamics.
The sound of Earth’s magnetic field, the first version of the magnetic field sonification produced with Swarm data, was originally played through a 32-speaker system set up in a public square in Copenhagen, with each speaker representing changes in the magnetic field at different places around the world over the past 100 000 years.

Sols 4282-4283: Bumping Away from Kings Canyon
NASA’s Mars rover Curiosity acquired this image using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm, on August 21, 2024, Sol 4280 of the Mars Science Laboratory Mission, at 00:18:12 UTC. NASA/JPL-Caltech/MSSS Earth planning date: Wednesday, Aug. 21, 2024
Having stayed in place for quite a few sols during our Kings Canyon drill campaign, we’re looking forward to doing a bump (ie: a short drive) and accomplishing some science in a new region. I’m on the SA-SPaH (ie: robotic arm) downlink team, which assess and reports on the success of robotic arm and drilling activities, including being closely involved in drilling campaigns. For awhile there was talk of doing a second Kings Canyon drill, but ultimately our planners decided against it. Though I always love getting involved with drill campaigns, we’re excited about our bump, which will take us near the “Fourth Recess Lake” area.
On sol 4282, we have some arm activities scheduled before a ~10 meter drive. During our first arm backbone, the rover will perform contact science on our “Marck Lake” target, including a DRT brushing and APXS integration. “Marck Lake” is a target just to the left of our existing Kings Canyon drill hole and supports our science studies for continuing to investigate this area’s lithology. We’ll also be doing some LIBS measurements on our drill tailings. This is to get extra data for supporting CheMin and SAM measurements.
After our arm activities, we’re taking advantage of a dust storm watch to do some extra environmental science. This watch comes because of a regional dust storm – visible even from the Earth – that has potential to evolve into a global dust storm. While it’s unusual to see global storms at this time of years, large planet encircling dust storms occur on Mars every three Mars years (about five and a half Earth years) on average. Even if they don’t turn into planet encircling events, regional dust storms on Mars can still grow quite large. The last regional dust storm on Mars occurred in early January of 2022 and had a surface area nearly twice the size of the United States. See this report from NASA for more information.
Towards the end of 4282, we will execute a ~10 meter drive towards the “Fourth Recess Lake” region. This area has numerous bright-toned clasts we’re excited to investigate for evidence of excess sulfur. For sol 4283, we have planned a ChemCam AEGIS activity, allowing autonomous target selection for upcoming geochemical spectrometry. If you’re interested in learning more about ChemCam AEGIS, check out this article.

An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope have directly imaged an exoplanet roughly 12 light-years from Earth. While there were hints that the planet existed, it had not been confirmed until Webb imaged it. The planet is one of the coldest exoplanets observed to date.

6 Min Read NASA’s Webb Images Cold Exoplanet 12 Light-Years Away
This image of the gas-giant exoplanet Epsilon Indi Ab was taken with the coronagraph on NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument). A star symbol marks the location of the host star Epsilon Indi A, whose light has been blocked by the coronagraph, resulting in the dark circle marked with a dashed white line (full image below) An international team of astronomers using NASA’s James Webb Space Telescope has directly imaged an exoplanet roughly 12 light-years from Earth. The planet, Epsilon Indi Ab, is one of the coldest exoplanets observed to date.
The planet is several times the mass of Jupiter and orbits the K-type star Epsilon Indi A (Eps Ind A), which is around the age of our Sun, but slightly cooler. The team observed Epsilon Indi Ab using the coronagraph on Webb’s MIRI (Mid-Infrared Instrument). Only a few tens of exoplanets have been directly imaged previously by space- and ground-based observatories.
Image A: Exoplanet Epsilon Indi Ab
This image of the gas-giant exoplanet Epsilon Indi Ab was taken with the coronagraph on NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument). A star symbol marks the location of the host star Epsilon Indi A, whose light has been blocked by the coronagraph, resulting in the dark circle marked with a dashed white line. Epsilon Indi Ab is one of the coldest exoplanets ever directly imaged. Light at 10.6 microns was assigned the color blue, while light at 15.5 microns was assigned the color orange. MIRI did not resolve the planet, which is a point source. “Our prior observations of this system have been more indirect measurements of the star, which actually allowed us to see ahead of time that there was likely a giant planet in this system tugging on the star,” said team member Caroline Morley of the University of Texas at Austin. “That’s why our team chose this system to observe first with Webb.”
“This discovery is exciting because the planet is quite similar to Jupiter — it is a little warmer and is more massive, but is more similar to Jupiter than any other planet that has been imaged so far,” added lead author Elisabeth Matthews of the Max Planck Institute for Astronomy in Germany.
Previously imaged exoplanets tend to be the youngest, hottest exoplanets that are still radiating much of the energy from when they first formed. As planets cool and contract over their lifetime, they become significantly fainter and therefore harder to image.
A Solar System Analog
“Cold planets are very faint, and most of their emission is in the mid-infrared,” explained Matthews. “Webb is ideally suited to conduct mid-infrared imaging, which is extremely hard to do from the ground. We also needed good spatial resolution to separate the planet and the star in our images, and the large Webb mirror is extremely helpful in this aspect.”
Epsilon Indi Ab is one of the coldest exoplanets to be directly detected, with an estimated temperature of 35 degrees Fahrenheit (2 degrees Celsius) — colder than any other imaged planet beyond our solar system, and colder than all but one free-floating brown dwarf. The planet is only around 180 degrees Fahrenheit (100 degrees Celsius) warmer than gas giants in our solar system. This provides a rare opportunity for astronomers to study the atmospheric composition of true solar system analogs.
“Astronomers have been imagining planets in this system for decades; fictional planets orbiting Epsilon Indi have been the sites of Star Trek episodes, novels, and video games like Halo,” added Morley. “It’s exciting to actually see a planet there ourselves, and begin to measure its properties.”
Not Quite As Predicted
Epsilon Indi Ab is the twelfth closest exoplanet to Earth known to date and the closest planet more massive than Jupiter. The science team chose to study Eps Ind A because the system showed hints of a possible planetary body using a technique called radial velocity, which measures the back-and-forth wobbles of the host star along our line of sight.
“While we expected to image a planet in this system, because there were radial velocity indications of its presence, the planet we found isn’t what we had predicted,” shared Matthews. “It’s about twice as massive, a little farther from its star, and has a different orbit than we expected. The cause of this discrepancy remains an open question. The atmosphere of the planet also appears to be a little different than the model predictions. So far we only have a few photometric measurements of the atmosphere, meaning that it is hard to draw conclusions, but the planet is fainter than expected at shorter wavelengths.”
The team believes this may mean there is significant methane, carbon monoxide, and carbon dioxide in the planet’s atmosphere that are absorbing the shorter wavelengths of light. It might also suggest a very cloudy atmosphere.
The direct imaging of exoplanets is particularly valuable for characterization. Scientists can directly collect light from the observed planet and compare its brightness at different wavelengths. So far, the science team has only detected Epsilon Indi Ab at a few wavelengths, but they hope to revisit the planet with Webb to conduct both photometric and spectroscopic observations in the future. They also hope to detect other similar planets with Webb to find possible trends about their atmospheres and how these objects form.
NASA’s upcoming Nancy Grace Roman Space Telescope will use a coronagraph to demonstrate direct imaging technology by photographing Jupiter-like worlds orbiting Sun-like stars – something that has never been done before. These results will pave the way for future missions to study worlds that are even more Earth-like.
These results were taken with Webb’s Cycle 1 General Observer program 2243 and have been published in the journal Nature.
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).
