NASA Gears Up for Major Cargo Resupply Mission to International Space Station

NASA, in collaboration with Northrop Grumman and SpaceX, is preparing for the launch of the Northrop Grumman Commercial Resupply Services 23 (CRS-23) mission, an event scheduled to commence no earlier than Sunday, September 14th, at 6:11 p.m. Eastern Daylight Time. This significant undertaking aims to deliver vital science investigations, essential supplies, and critical equipment to the International Space Station (ISS). The mission’s cargo will be transported aboard Northrop Grumman’s Cygnus XL spacecraft, a new and enhanced version of their solar-powered vehicle, which will be launched on a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida.

The Cygnus XL spacecraft is poised to carry over 11,000 pounds of cargo. Following its launch, astronauts aboard the ISS are expected to capture the Cygnus XL using the station’s Canadarm2 robotic arm on Wednesday, September 17th. This maneuver will be followed by the robotic installation of the spacecraft to the Unity module’s Earth-facing port, facilitating the subsequent unloading of its contents.

Among the key scientific endeavors and technology demonstrations slated to benefit from this resupply are experiments focused on producing semiconductor crystals in the unique environment of space. Additionally, equipment will be delivered to aid in the development of improvements for cryogenic fuel tanks. The mission will also deliver a specialized ultraviolet light system designed to combat the growth of microbial communities that can form in water systems. Furthermore, supplies will be provided for the production of pharmaceutical crystals, potentially leading to advancements in treatments for cancer and other diseases.

The Cygnus XL, christened the S.S. William “Willie” McCool, is named in honor of NASA astronaut William McCool, who tragically perished in the 2003 space shuttle Columbia accident. The spacecraft is scheduled to remain docked at the orbiting laboratory until March, at which point it will depart and perform a controlled burn-up in Earth’s atmosphere.

NASA will provide comprehensive coverage of the launch and arrival, accessible through platforms such as NASA+, Amazon Prime, and various social media channels. Prior to the launch, the agency has scheduled a series of informational events. A webinar focusing on International Space Station National Laboratory science is set for Wednesday, September 10th, at 1 p.m. Eastern Time, featuring a panel of experts including Dr. Liz Warren from NASA’s ISS Program Research Office and Phillip Irace, science program director for the ISS National Laboratory, among others. Media interested in participating in this webinar must register for Zoom access at least one hour prior to its commencement. The webinar will be recorded and made available on the International Space Station National Lab’s YouTube channel.

A prelaunch media teleconference is scheduled for Friday, September 12th, at 11:30 a.m. Eastern Time. This briefing will include participation from Dina Contella, deputy manager of NASA’s International Space Station Program, and representatives from Northrop Grumman and SpaceX. Media outlets wishing to join the teleconference by phone must request dial-in information by 5 p.m. on Thursday, September 11th, by contacting the NASA Johnson newsroom. Audio of the teleconference will be live-streamed on NASA’s website and YouTube channel.

Launch day coverage will commence on NASA+ and Amazon Prime at 5:50 p.m. Eastern Daylight Time on September 14th, with the launch itself targeted for 6:11 p.m. On the day of arrival, Wednesday, September 17th, coverage of the capture of the Cygnus XL is scheduled to begin at 5 a.m. Eastern Daylight Time, with the installation coverage beginning at 8 a.m.

The NASA website will also feature live streaming and blog updates on launch day, starting no earlier than 5:50 p.m. On-demand streaming video and photos will be available shortly after liftoff. Members of the public can register to attend the launch virtually, which includes access to curated launch resources and notifications.

NASA encourages the public to engage with the mission on social media platforms including X, Facebook, and Instagram, by following and tagging relevant NASA accounts. Spanish-language coverage will also be available through NASA en Español’s social media channels and website.
