Cygnus XL Cargo Craft Counts Down to Launch on NASA+

Northrop Grumman’s Cygnus spacecraft, atop a SpaceX Falcon 9 rocket, soars from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida on Sunday, Aug. 4, 2024, for the 21st Northrop Grumman commercial resupply mission for NASA. The spacecraft is expected to reach the space station Tuesday, Aug. 6, bringing 8,200 pounds of science investigations, supplies, and equipment for the international crew.

NASA’s coverage is underway on NASA+, Amazon Prime, and more for the launch of Northrop Grumman’s Commercial Resupply Services 23, or Northrop Grumman CRS-23, to the International Space Station. Learn how to watch NASA content through a variety of platforms, including social media.

The company’s Cygnus XL spacecraft is scheduled for liftoff at 6:11 p.m. EDT on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

Filled with more than 11,000 pounds of scientific investigations, food, supplies, and equipment, Cygnus XL will arrive at the orbiting outpost on Wednesday, Sept. 17. NASA astronaut Jonny Kim will capture the spacecraft using the station’s Canadarm2 robotic arm, with assistance from NASA astronaut Zena Cardman. After capture, the spacecraft will be installed on the Unity module’s Earth-facing port for cargo unloading.

This mission will be the first flight of the Cygnus XL, the larger, more cargo-capable version of the company’s solar-powered spacecraft. Northrop Grumman has named the spacecraft the S.S. William “Willie” C. McCool, in honor of the NASA astronaut who perished in 2003 during the space shuttle Columbia accident.

Mechele Elliott Safeguards Agency Information Systems at Johnson

Mechele Elliott Safeguards Agency Information Systems at Johnson

As an IT security administrator at NASA’s Johnson Space Center in Houston, Mechele Elliott protects the information systems that support astronaut health and mission readiness.

The encouragement of a family friend set her on this path, leading to a rewarding and somewhat unexpected career in human spaceflight.

“While I was caring for my son during his cancer treatment—living in the hospital with him and supporting his recovery at home—a family friend who worked at NASA took notice,” Elliott said. “She quietly observed my strength, organization, and unwavering dedication to my son. One day she called and said, ‘Get your resume together.’”

Elliott doubted she was qualified for a position at NASA, though the friend was certain she could learn and handle anything after caring for her son. “Her belief in me gave me the courage to take that first step—and it changed the course of my life.”

The friend’s endorsement helped her land the position. Elliott was nervous at first, since she did not know much about NASA’s operations and had limited prior experience. With time and training, she grew more certain of the value she brought to the team.

“Reflecting on the numerous personal challenges I have encountered has reinforced my confidence in my ability to overcome obstacles while maintaining a positive outlook throughout my journey,” she said. “I am proud to have successfully adapted and become a productive member of my team.” In her role today, Elliott safeguards NASA’s information systems. She develops, implements, and maintains security policies, procedures, and systems in the Human Health and Performance Directorate, ensuring compliance with federal and NASA-specific security standards. Her work includes managing access control protocols and responding  to security incidents.

One of her most challenging tasks involved assessing, revitalizing, and implementing four outdated security plans through collaboration with a diverse team. “We successfully aligned the security plans with established standards and garnered commendations from NASA leadership,” she said.

Outside of work, Elliott enjoys several hobbies that help her relax and maintain balance. She began painting at a young age and continues to find calm through her art. She is an avid gardener, in spite of the Houston summer heat, and feels fulfilled by the beauty of her flowers and sharing homegrown fruits and vegetables with her friends and family. She has also earned a reputation as an excellent baker. “I enjoy making cheesecakes for workplace celebrations and I’ve discovered that many of my coworkers enjoy this hobby of mine, as well!”

Elliott is profoundly grateful for the opportunity to serve at NASA for over 25 years. Looking ahead to the agency’s future, she offers an important piece of advice to up-and-coming team members. “Remain authentic to yourselves, pursue your aspirations with determination, and uphold a commitment to excellence in all your endeavors.”

Curiosity Blog, Sols 4649-4654: Ridges, Hollows and Nodules, Oh My

A grayscale photo from the Martian surface shows a rough, rocky landscape in medium gray, with a shadow of the Curiosity rover’s boxy masthead showing at the center of the frame, and the shadow of its body covering some of the bottom of the frame. Along an uneven vertical border from the top to the bottom of the image, the texture of the terrain is separated from more ground-up soil and rock of many sizes, while the right side is covered in larger, flatter rocks, with numerous cracks and crevices separating them from each other.
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera, showing the transition from smoother ridge bedrock (right) to more nodular bedrock (bottom left to top middle) on the edge of a shallow hollow (top left). Curiosity, whose masthead shadow is also visible, captured this image on Sept. 5, 2025 — Sol 4650, or Martian day 4,650 of the Mars Science Laboratory mission — at 00:22:34 UTC.

Earth planning date: Friday, Sept. 5, 2025

Curiosity is in the midst of the boxwork campaign, trying to decipher why we see such pronounced ridges and hollows in this area of Mount Sharp. When this terrain was first identified from orbit it was hypothesized that the ridges may be the result of cementation by circulating fluids, followed by differential erosion of the less resistant bedrock in between (the hollows that we now observe). 

We have been exploring the boxwork terrain documenting textures, structures and composition to investigate potential differences between ridges and hollows. One of the textural features we have observed are nodules in varying abundance. The focus of our activities this week was to document the transition from smoother bedrock atop a boxwork ridge to more nodular bedrock associated with the edge of a shallow hollow. 

In Tuesday’s three-sol plan we analyzed the smoother bedrock within the ridge, documenting textures with MAHLI, Mastcam, and ChemCam RMI, and chemistry with ChemCam LIBS and APXS. Curiosity then successfully bumped towards the edge of the ridge/hollow to place the more nodular bedrock in our workspace. Friday’s three-sol plan was basically a repeat of the previous observations, but this time focused on the more nodular bedrock. The planned drive should take us to another boxwork ridge, and closer to the area where we plan to drill into one of the ridges.

As the APXS strategic planner this week, I helped to select the rock targets for analysis by our instrument, ensuring they were safe to touch and that they met the science intent of the boxwork campaign. I also communicated to the rest of the team the most recent results from our APXS compositional analyses and how they fit into our investigation of the boxwork terrain. This will help to inform our fast-approaching decision about where to drill.

Both plans included Mastcam and ChemCam long-distance RMI imaging of more distant features, including other boxwork ridges and hollows, buttes, the yardang unit, and Gale crater rim. Planned environmental activities continue to monitor dust in the atmosphere, dust-devil activity, and clouds. Standard REMS, RAD, and DAN activities round out the week’s activities.
