Technicians with ESA (European Space Agency) and Airbus installed the four solar array wings on NASA’s Orion spacecraft for Artemis II on March 3. The solar array wings, attached to the service module, deploy after Orion reaches space to power the spacecraft.
Orion’s service module provides propulsion, thermal control, and electrical power, as well as air and water for the crew during their mission around the Moon.
Each solar array wing has 15,000 solar cells to convert sunlight to electricity and is nearly 23 feet in length when fully deployed. In space, the arrays can turn on two axes to remain aligned with the Sun.
Artemis II is the first crewed mission under NASA’s Artemis campaign. Through Artemis, the agency will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

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.

The National Society of Professional Engineers recently named Debbie Korth, Orion deputy program manager at Johnson Space Center, as NASA’s 2025 Engineer of the Year. Korth was recognized during an award ceremony at the National Press Club in Washington, D.C., on Feb. 21, alongside honorees from 17 other federal agencies. The annual awards program honors the impactful contributions of federal engineers and their commitment to public service.
Debbie Korth received the NASA 2025 Engineer of the Year Award from the National Society of Professional Engineers at the National Press Club in Washington, D.C. Image courtesy of Debbie Korth Korth said she was shocked to receive the award. “At NASA there are so many brilliant, talented engineers who I get to work with every day who are so specialized and know so much about a certain area,” she said. “It was very surprising, but very appreciated.”
Korth has dedicated more than 30 years of her career to NASA, supporting human spaceflight development, integration, and operations across the Space Shuttle, International Space Station, and Orion Programs. Her earliest roles involved extravehicular and mission operations planning, as well as managing spaceflight hardware for shuttle missions and space station crews. Working on hardware such as the Crew Health Care System in the early days of space station planning and development was a unique experience for Korth.
After spending significant time in Russia collaborating with Russian counterparts to integrate equipment such as a treadmill, cycle ergometer, and blood pressure monitor into their module, Korth recalled, “When we finally got that all delivered and integrated, it was a huge step because we had to have all of that on board before we could put crew members on the station for the first time. I remember feeling a huge sense of accomplishment and happiness that we were able to work through this international partnership and forge those relationships to get that hardware integrated.”
Korth transitioned to the Orion Program in 2008 and has since served in a variety of leadership roles. In her current role, Korth assists the program manager in the design, development, testing, verification, and certification of Orion, NASA’s next-generation, human-rated spacecraft for Artemis missions. The spacecraft’s first flight test around the Moon during the Artemis I mission was a standout experience for Korth and a major accomplishment for the Orion team.
“It was a long mission and every day we were learning more and more about the spacecraft and pushing boundaries,” she said. “We really wrung out some of the core systems – systems that were developed individually and for the first time we got to see them work together.”
Korth said that understanding how different systems interact with each other is what she loves most about engineering. “In systems engineering, you really look at how changes to and the performance of one system affects everything else,” she said. “I like looking across the entire spacecraft and saying, if I have to strengthen this structure to take some additional landing loads, that’s going to add mass to the vehicle, which means I have to look at my parachutes and the thermal protection system to make sure they can handle that increased load.”
The Orion team is working to achieve two major milestones in 2025 – delivery of the Artemis II Orion spacecraft to the Exploration Ground Systems team that will fuel and integrate Orion with its launch abort system at NASA’s Kennedy Space Center, and the spacecraft’s integration with the Space Launch System rocket, which is currently being stacked. These milestones will support the launch of the first crewed mission on NASA’s path to establishing a long-term presence at the Moon for science and exploration, with liftoff targeted no earlier than April 2026.
“It’s going to be a big year,” said Korth.

Have you ever looked up and seen the sky split into two distinct colors, one side glowing red while the other remains a dull gray? At first glance, it may seem like a natural optical effect, but it is not!
Watch video of this bizarre sky phenomenon below.
This phenomenon has been observed before, and many believe it is not just a random occurrence. Instead, it could be the result of large-scale geoengineering projects, deliberate interventions in Earth's climate system. These efforts, often carried out under the guise of combating climate change, may actually be disrupting natural atmospheric processes.
Strange, unnatural-looking clouds, such as square formations and other unusual weather anomalies, may also be linked to these operations.
Additionally, the infamous chemtrails are a product of weather manipulation, involving the release of chemicals into the lower stratosphere. Proponents argue that these methods help mitigate global warming, but that is not true, these sprayings really doing more harm than good.
While mainstream narratives push the climate change (hoax) agenda and link climate change to human activity and greenhouse gas emissions, an increasing number of scientists step forward and explain that natural Earth cycles, particularly its position relative to the sun, play a significant role in climate shifts. They point to Milankovitch cycles—long-term variations in Earth's orbit and axial tilt, which have historically played a key role in global temperature changes.
Interestingly, it seems that some high-ranking government officials are beginning to question the effects of geoengineering. If action is taken to regulate or halt these practices, we may once again witness unaltered, natural skies. Until then, all we can do is observe, question, and seek the truth. View the full article

Jorge Chong is helping shape the future of human spaceflight, one calculation at a time. As a project manager for TRON (Tracking and Ranging via Optical Navigation) and a guidance, navigation, and control (GNC) test engineer in the Aeroscience and Flight Mechanics Division, he is leading efforts to ensure the Orion spacecraft can navigate deep space autonomously.

It involves a suite of sensors that keep track of where the vehicle is in orbit so it can return home safely,” he said. “Getting to test the components of a GNC system makes you very familiar with how it all works together, and then to see it fly and help it operate successfully is immensely rewarding.”
His work is critical to the Artemis campaign, which aims to return humans to the Moon and pave the way for Mars. From developing optical navigation technology that allows Orion to determine its position using images of Earth and the Moon to testing docking cameras and Light Detection and Ranging systems that enable autonomous spacecraft rendezvous, Chong is pushing the limits of exploration. He also runs high-fidelity flight simulations at Lockheed Martin’s Orion Test Hardware facility in Houston, ensuring Orion’s software is ready for the demands of spaceflight.
Chong’s NASA career spans seven years as a full-time engineer, plus three years as a co-op student at NASA’s Johnson Space Center in Houston. In 2024, he began leading Project TRON, an optical navigation initiative funded by a $2 million Early Career Initiative award. The project aims to advance autonomous space navigation—an essential capability for missions beyond Earth’s orbit.

Bottom right: Steve Lockhart and Ronney Lovelace. Thanks to Chong’s work, the Artemis Generation is one step closer to exploring the Moon, Mars, and beyond. He supported optical navigation operations during Artemis I, is writing software that will fly on Artemis II, and leads optical testing for Orion’s docking cameras. But his path to NASA wasn’t always written in the stars.
“I found math difficult as a kid,” Chong admits. “I didn’t enjoy it at first, but my parents encouraged me patiently, and eventually it started to click and then became a strength and something I enjoyed. Now, it’s a core part of my career.” He emphasizes that perseverance is key, especially for students who may feel discouraged by challenging subjects.
Most of what Chong has learned, he says, came from working collaboratively on the job. “No matter how difficult something may seem, anything can be learned,” he said. “I could not have envisioned being involved in projects like these or working alongside such great teams before coming to Johnson.”

Image courtesy of Jorge Chong His career has also reinforced the importance of teamwork, especially when working with contractors, vendors, universities, and other NASA centers. “Coordinating across these dynamic teams and keeping the deliverables on track can be challenging, but it has helped to be able to lean on teammates for assistance and keep communication flowing,” said Chong.
And soon, those systems will help Artemis astronauts explore places no human has gone before. Whether guiding Orion to the Moon or beyond, Chong’s work is helping NASA write the next chapter of space exploration.
“I thank God for the doors He has opened for me and the incredible mentors and coworkers who have helped me along the way,” he said.
