The NASA Ames Science Directorate recognizes the outstanding contributions of (pictured left to right) Jessica Kong, Josh Alwood, and Sam Kim. Their commitment to the NASA mission represents the entrepreneurial spirit, technical expertise, and collaborative disposition needed to explore this world and beyond.
Space Science and Astrobiology Star: Jessica Kong
Jessica Kong is serving as the Facility Service Manager (FSM) for the Astrobiology and Life Science Lab building for the Exobiology Branch while the FSM is away on parental leave. She has applied her expertise as a chemist to connect seamlessly and effectively with N239 staff, and safety, and facility personnel, as well as to coordinate repairs and building shutdowns while minimizing disruption to laboratory research.
Space Biosciences Star: Josh Alwood
Josh Alwood is a researcher for the Space Biosciences Research Branch, focusing on bone biology and biomechanics, reproductive biology, and the nervous system. His pioneering research on molecular mechanisms of skeletal adaptation during spaceflight has advanced the development of countermeasures to protect astronaut health on long-duration missions.
Earth Science Star: Sam Kim
Sam Kim, a systems administrator and deputy project manager with the Earth Science Project Office (ESPO), serves many roles and excels in each one of them. During the 2024 ASIA-AQ field mission, Sam deployed for over two months as a key member of the advanced staging team at each of the mission’s four overseas field sites, ensuring that the facilities were ready for the arrival of the ASIA-AQ science and instrument team, while still performing his mission-critical role as systems administrator.

Challenges to measuring space-induced brain changes
CSA (Canadian Space Agency) astronaut David Saint-Jacques undergoes an MRI for Wayfinding. CSA Researchers found that an upward shift in the brain during spaceflight makes it hard to distinguish different types of tissue, causing errors in determining changes in brain volume. Previous studies have interpreted these changes as evidence of adaptation to space. This finding suggests that unique methods are needed to analyze astronaut brain structure.
Wayfinding, a CSA (Canadian Space Agency) investigation, looked at how the brain adapts to space and readapts after return to normal gravity using a variety of assessments, including neuroimaging. The researchers propose that previous data could be reanalyzed based on the errors identified by this paper.
Catching micrometeoroids
JAXA’s (Japan Aerospace Exploration Agency) Tanpopo panels were mounted on the Exposed Experiment Handrail Attachment Mechanism (ExHAM) at top center of this image. JAXA/Takuya Onishi An impact track made by a micrometeoroid on a panel outside the International Space Station contained iron and orthopyroxene crystals. This finding, along with previous studies, suggests that micrometeoroids containing these elements are abundant in low Earth orbit and more measurements are needed to determine their origins and potential for carrying life.
At least 90% of meteoroids at one astronomical unit or AU (93 million miles or the distance between Earth and the Sun) do not reach Earth’s surface, so investigating those in low Earth orbit is key to understanding their nature. The JAXA (Japan Aerospace Exploration Agency) Tanpopo experiment placed blocks of a special gel outside the station to capture solid microparticles to test the theory that they could transport life among celestial bodies. Most meteoroids at one AU may have originated from Jupiter family comets.

What Are Messier Objects?
During the 18th century, astronomer and comet hunter Charles Messier wanted to distinguish the ‘faint fuzzies’ he observed from any potential new comets. As a result, Messier cataloged 110 objects in the night sky, ranging from star clusters to galaxies to nebulae. These items are designated by the letter ‘M’ and a number. For example, the Orion Nebula is Messier 42 or M42, and the Pleiades are Messier 45 or M45. These are among the brightest ‘faint fuzzies’ we can see with modest backyard telescopes and some even with our eyes.
Stargazers can catalog these items on evenings closest to the new moon. Some even go as far as having “Messier Marathons,” setting up their telescopes and binoculars in the darkest skies available to them, from sundown to sunrise, to catch as many as possible. Here are some items to look for this season:
M44 in Cancer and M65 and 66 in Leo can be seen high in the evening sky 60 minutes after sunset. Stellarium Web Messier 44 in Cancer: The Beehive Cluster, also known as Praesepe, is an open star cluster in the heart of the Cancer constellation. Use Pollux in Gemini and Regulus in Leo as guide stars. A pair of binoculars is enough to view this and other open star clusters. If you have a telescope handy, pay a visit two of the three galaxies that form the Leo Triplet – M65 and M66. These items can be seen one hour after sunset in dark skies.
Locate M3 and M87 rising in the east after midnight. Stellarium Web Messier 3 Canes Venatici: M3 is a globular cluster of 500,000 stars. Through a telescope, this object looks like a fuzzy sparkly ball. You can resolve this cluster in an 8-inch telescope in moderate dark skies. You can find this star cluster by using the star Arcturus in the Boötes constellation as a guide.
Messier 87 in Virgo: Located just outside of Markarian’s Chain, M87 is an elliptical galaxy that can be spotted during the late evening hours. While it is not possible to view the supermassive black hole at the core of this galaxy, you can see M87 and several other Messier-labeled galaxies in the Virgo Cluster using a medium-sized telescope.
Locate M76 and M31 setting in the west, 60 minutes after sunset. Stellarium Web Plan Ahead
When gearing up for a long stargazing session, there are several things to remember, such as equipment, location, and provisions:
Do you have enough layers to be outdoors for several hours? You would be surprised how cold it can get when sitting or standing still behind a telescope! Are your batteries fully charged? If your telescope runs on power, be sure to charge everything before you leave home and pack any additional batteries for your cell phone. Most people use their mobile devices for astronomy apps, so their batteries may deplete faster. Cold weather can also impact battery life. Determine the apparent magnitude of what you are trying to see and the limiting magnitude of your night sky. You can learn more about apparent and limiting magnitudes with our Check Your Sky Quality with Orion article. When choosing a location to observe from, select an area you are familiar with and bring some friends! You can also connect with your local astronomy club to see if they are hosting any Messier Marathons. It’s always great to share the stars! You can see all 110 items and their locations with NASA’s Explore the Night Sky interactive map and the Hubble Messier Catalog, objects that have been imaged by the Hubble Space Telescope.
