Northrop Grumman’s Cygnus cargo craft awaits its capture by the International Space Station’s Canadarm2 robotic arm, commanded by NASA astronaut Matthew Dominick on Aug. 6, 2024.Credit: NASA NASA, Northrop Grumman, and SpaceX are targeting no earlier than 6:11 p.m. EDT, Sunday, Sept. 14, for the next launch to deliver science investigations, supplies, and equipment to the International Space Station. The mission is known as NASA’s Northrop Grumman Commercial Resupply Services 23, or Northrop Grumman CRS-23.

Filled with more than 11,000 pounds of supplies, the Northrop Grumman Cygnus XL spacecraft, carried on a SpaceX Falcon 9 rocket, will launch from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. This mission will be the first flight of the Cygnus XL, the larger, more cargo-capable version of the company’s solar-powered spacecraft.
Following arrival, astronauts aboard the space station will use the Canadarm2 to grapple Cygnus XL on Wednesday, Sept. 17, before robotically installing the spacecraft to the Unity module’s Earth-facing port for cargo unloading.
Highlights of space station research and technology demonstrations, facilitated by delivery aboard this Cygnus XL, include materials to produce semiconductor crystals in space and equipment to develop improvements for cryogenic fuel tanks. The spacecraft also will deliver a specialized UV light system to prevent the growth of microbe communities that form in water systems and supplies to produce pharmaceutical crystals that could treat cancer and other diseases.
Media interested in speaking to a science subject matter expert should contact Sandra Jones at: sandra.p.jones@nasa.gov. A copy of NASA’s media accreditation policy is available on the agency’s website.
The Cygnus XL spacecraft is scheduled to remain at the orbiting laboratory until March before it departs and burns up in the Earth’s atmosphere. Northrop Grumman has named the spacecraft the S.S. William “Willie” McCool, in honor of the NASA astronaut who perished in 2003 during the space shuttle Columbia accident.

Curiosity Blog, Sols 4609–4610: Recharged and Ready To Roll Onwards
NASA’s Mars rover Curiosity acquired this image showing the boxwork hollow where it is investigating, and the boxwork ridge on the far side of the hollow, using its Left Navigation Camera. Curiosity captured the image on July 20, 2025 — Sol 4605, or Martian day 4,605 of the Mars Science Laboratory mission — at 18:51:55 UTC.

Earth planning date: Wednesday, July 23, 2025
For today’s planning, we were in the same workspace as the Monday plan — on purpose! We don’t often have a plan without a drive but in order to allow the battery to recover from some power-hungry SAM atmospheric measurements over the weekend and on Monday, we needed to stay put and skip our usual drive. As a result, we gained a bonus planning cycle at this interesting workspace.
We are in one of the “hollows” between the resistant ridges of the “boxwork” terrain, as you can see in the image for this blog. This made for a quieter Operations day for me as the APXS planner. As Deborah noted in Monday’s blog, we have already gotten three APXS and MAHLI measurements in this workspace, so we didn’t acquire more in this plan.
This morning, we focused on documenting some small light-toned, rounded, white pebbles in the workspace (you can see them in the accompanying Navcam image), which look very different from the underlying bedrock. We used our one ChemCam LIBS analysis for the plan on “Yana Qaqa.” Mastcam will image this pebble, another at “Ojos del Salado,” and a really cool-looking target with a dendritic-looking texture at “Punta de Lobos.”
Further afield, Mastcam will image the adjacent boxwork ridge and hollow in our drive direction, and a series of troughs with raised edges to the right of our current workspace. ChemCam will image a long-distance RMI mosaic of “Cueva de los Vencejos y Murciélagos,” which was imaged by Mastcam on Monday, and also acquire some further images of the “Mishe Mokwa” hill.
We had a bumper couple of sols of atmospheric measurements over the weekend and Monday. Now we revert back to our more normal environmental and atmospheric monitoring. These do not get as much attention sometimes as the amazing images we take of the fascinating rocks we see, but have been taking place consistently and continuously since Curiosity’s landing almost 13 years ago now. This plan includes a series of Navcam movies (suprahorizon, dust devil) and a line-of-sight observation of dust, standard REMS and DAN observations, and two Mastcam tau measurements, looking at dust in the atmosphere.
Our 24-meter drive (almost 79 feet) will take us out of this hollow and back up on top of a ridge. From here, we hope to be able to spy the best driving path through the boxwork. The ridges are up to 5 meters in diameter (about 16 feet), so we are cautiously hopeful that we can just trundle along one of the ridges as we investigate this fascinating terrain.
