Preventing biofilm formation in space
Ashley Keeley, University of Idaho, holds an anti-bacterial coating sample.University of Idaho Student Payload Opportunity with Citizen Science Team Two anti-microbial coatings reduced formation of biofilms in microgravity and have potential for use in space. Controlling biofilms could help protect human health and prevent corrosion and degradation of equipment on future long-duration space missions.
Biofilms, communities of microorganisms that attach to a surface, can damage mechanical systems and present a risk of disease transmission. Bacteria Resistant Polymers in Space examined how microgravity affects polymer materials designed to prevent or reduce biofilm formation. Better anti-fouling coatings also could reduce disease transmission on Earth.
Evaluating organ changes in lunar gravity
Set up for the Mouse Epigenetics experiment aboard the International Space Station. NASA Researchers found different changes in gene expression and other responses to simulated lunar gravity levels in specific organs. This finding could help determine safe gravity thresholds and support development of ways to maintain skeletal and immune function on future space journeys.
Spaceflight can affect skeletal and immune system function, but the molecular mechanisms of these changes are not clear. Mouse Epigenetics, a JAXA (Japan Aerospace Exploration Agency) investigation, studied gene expression changes in mice that spent a month in space and in the DNA of their offspring. Results could help determine spaceflight’s long-term effects on genetic activity, including changes within individual organs and those that can be inherited later.
Performance report for cosmic ray observatory
The CALorimetric Electron Telescope instrument is visible on the far left of the space station’s Kibo laboratory module. JAXA (Japanese Aerospace Exploration Agency)/Norishige Kanai Researchers report on-orbit performance from the first 8 years of operation of the International Space Station’s cosmic ray observatory, CALET. The instrument has provided valuable data on cosmic ray, proton, and helium spectra; produced a gamma-ray sky map; observed gamma-ray bursts; and searched for gravitational wave counterparts and solar effects.
The JAXA CALorimetric Electron Telescope or CALET helps address questions such as the origin and acceleration of cosmic rays and the existence of dark matter and nearby cosmic-ray sources. The instrument also could help characterize risks from the radiation environment that humans and electronics experience in space.

Official NASA portrait of Norman D. Knight. Credit: NASA NASA has selected Norman Knight as acting deputy director of Johnson Space Center. Knight currently serves as Director of Johnson’s Flight Operations Directorate (FOD), responsible for astronaut training and for overall planning, directing, managing, and implementing overall mission operations for NASA human spaceflight programs. This also includes management for all Johnson aircraft operations and aircrew training. Knight will serve in this dual deputy director and FOD director role for the near term.
“It is an honor to accept my new role as acting deputy director for Johnson,” Knight said. “Human spaceflight is key to our agency’s mission and our Johnson team is unified in that goal. The successes we see every day are the evidence of that. It never ceases to amaze me what our team is capable of.”
Knight began his career at the Johnson Space Center as a Space Shuttle mechanical systems flight controller, working 40 missions in this capacity. He progressed through management roles with increasing responsibility, and in 2000, he was selected as a flight director and worked in that capacity for numerous International Space Station expeditions and Space Shuttle missions. In 2009, he became the deputy chief of the Flight Director Office and participated in a NASA fellowship at Harvard Business School in general management. In 2012, Knight was selected as the chief of the Flight Director Office and then in 2018 as deputy director of the Flight Operations Directorate after serving a temporary assignment as the assistant administrator, Human Exploration and Operations Mission Directorate at NASA Headquarters. In 2021, Knight was selected as the director of FOD.
“Norm has an accomplished career within the agency,” said Steven Koerner, Johnson acting director. “His leadership, expertise, and dedication to the mission will undoubtably drive our continued success.”
Throughout his career, Knight has been recognized for outstanding technical achievements and leadership, receiving a Spaceflight Awareness Honoree award for STS-82. He also received several center and agency awards, including two Exceptional Achievement medals, multiple Johnson and agency group achievement awards, two Superior Accomplishment awards, an Outstanding Leadership medal, the Johnson Director’s Commendation award, and the Distinguished Service medal.
Knight earned a bachelor’s degree in aeronautical engineering from the Embry Riddle Aeronautical University in 1990.

Skywatching Science Skywatching What’s Up: March 2025… Skywatching Home What’s Up What to See Tonight Moon Guide Eclipses Meteor Showers More Tips & Guides Skywatching FAQ A Fast-Moving Planet and a Crimson Moon!
Catch Mercury if you can, then stay up late for a total lunar eclipse, and learn the truth about the dark side of the Moon.
Skywatching Highlights
All Month – Planets Visibility:
Mercury: Speedy Mercury is visible beneath Venus for the first week and a half of March, for about 30 minutes each evening, as sunset fades. Venus: Venus hangs low in the west after sunset early in the month, but quickly drops lower as the days pass. After mid-March, it’s difficult to observe in the glow of fading sunlight. Mars: Find Mars high in the east following sunset, then setting around 3 a.m. Jupiter: Visible high in the west after dark, and setting about 1 a.m. Daily Highlights:
March 7-9 – Catch Mercury: Look for Mercury beginning about 30 minutes after sunset in the west, about 10 degrees above the horizon.
March 13-14 – Total Lunar Eclipse: The Moon becomes a crimson orb over a couple of hours on March 13th and into the 14th, depending on your time zone.
March 14 – Full moon
March 29 – New moon: This is when the dark side of the Moon faces toward Earth. The new moon appears close to the Sun in the sky, so it’s essentially invisible from the surface (except during solar eclipses).

What’s Up for March? A good time to catch Mercury, an eclipse approaches, and the dark side of the Moon.
March Planet Viewing
March begins with Venus still hanging out low in the west after sunset, but it quickly drops out of the sky – by mid-month it’s getting lost in the glare of sunset. Once it gets dark, you’ll find Jupiter and Mars high overhead, keeping you company through the evening. Mars sets a couple of hours after midnight this month, leaving the morning sky “planet free” for the first time in a year.
Sky chart showing Venus and Mercury after sunset in early March. NASA/JPL-Caltech March also has the best opportunity this year for trying to spot fast-moving Mercury if you’re in the Northern Hemisphere. It’s only visible for a few weeks at a time every 3 to 4 months. This is because the speedy planet orbits the Sun in just 88 days, so it quickly shifts its position in the sky from day to day. It’s always visible either just after sunset or just before sunrise. On March 7th through 9th, look for Mercury beginning about 30 minutes after sunset in the west, about 10 degrees above the horizon.
You’ll want to ensure your view isn’t blocked by trees, buildings, or other obstructions. Observing from a large, open field, or the shore of a lake or the seaside can be helpful. Spying Mercury isn’t always easy, but catching the fleet-footed planet is a worthy goal for any skywatcher.
Total Lunar Eclipse
This map shows where the Moon will be above the horizon during the March 13-14 total lunar eclipse. There’s a total lunar eclipse on the way this month, visible across the Americas. Lunar eclipses can be viewed from anywhere the Moon is above the horizon at the time. The show unfolds overnight on March 13th and into the 14th, depending on your time zone. Check the schedule for your area for precise timing.
Now, during a total lunar eclipse, we watch as the Moon passes through Earth’s shadow. It first appears to have a bite taken out of one side, but as maximum eclipse nears, the Moon transforms into a deep crimson orb. That red color comes from the ring of all the sunsets and sunrises you’d see encircling our planet if you were an astronaut on the lunar surface right then. Afterward, the eclipse plays out in reverse, with the red color fading, and the dark bite shrinking, until the Moon looks like its usual self again.
And here’s an interesting pattern: eclipses always arrive in pairs. A couple weeks before or after a total lunar eclipse, there’s always a solar eclipse. This time, it’s a partial solar eclipse that will be visible across Eastern Canada, Greenland, and Northern Europe.
The Dark Side of the Moon
The Moon has a dark side, but it may not be what you think. As it orbits around Earth each month, the Moon is also rotating (or spinning). So, while we always see the same face of the Moon, sunlight sweeps across the lunar surface every month as it rotates.
This means there’s no permanently “dark” side. The Moon’s dark side faces Earth when the Moon passes between our planet and the Sun each month. This is the moment when the Moon is said to be “new,” as in a fresh start for its changing phases.
The new moon is also located quite close the Sun in the sky, making it more or less invisible, unless there’s a solar eclipse.
Nights around the new moon phase provide excellent opportunities for observing the sky – especially if you’re using a telescope or doing astrophotography. Without moonlight washing out the sky, you can better see faint stars, nebulas, the Milky Way, and distant galaxies. So next time someone mentions the “dark side of the Moon,” you’ll know there’s more to the story – and you might even discover some deep-sky treasures while the Moon takes its monthly break.
