NASA, Northrop Grumman, and SpaceX are targeting 11:28 a.m. EDT on Saturday, Aug. 3, for the next launch to deliver science investigations, supplies, and equipment to the International Space Station. This launch is the 21st Northrop Grumman commercial resupply services mission to the orbital laboratory for the agency.

NASA’s live launch coverage will begin at 11:10 a.m. on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. Learn how to stream NASA TV through a variety of platforms, including social media.

Filled with nearly 8,200 pounds of supplies, the Northrop Grumman Cygnus spacecraft, carried on the SpaceX Falcon 9 rocket, will launch from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

NASA coverage of arrival will begin at 2:30 a.m. Monday, Aug. 5 on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. NASA astronaut Matthew Dominick will capture Cygnus using the station’s robotic arm, and NASA astronaut Jeanette Epps will act as backup to Dominick. After capture, the spacecraft will be installed on the Unity module’s Earth-facing port.

Highlights of space station research facilitated by delivery aboard this Cygnus are:

  • Test articles to evaluate liquid and gas flow through porous media found in space station life support systems.
  • A balloon, penny, and hexnut for a new STEMonstration on centripetal force.
  • Microorganisms known as Rotifers to examine the effects of spaceflight on DNA repair mechanisms.
  • A bioreactor to demonstrate the production of many high-quality blood and immune stem cells.
  • Vascularized liver tissue to analyze the development of blood vessels in engineered tissue flown to the space station.

NASA’s CubeSat Launch Initiative also is sending two CubeSats to deploy from the orbiting laboratory, CySat-1 from Iowa State University and DORA (Deployable Optical Receiver Aperture) from Arizona State University, making up ELaNa 52 (Educational Launch of Nanosatellites).

Media interested in speaking to a science subject matter expert, should contact Sandra Jones at sandra.p.jones@nasa.gov.

The Cygnus spacecraft is scheduled to remain at the space station until January when it will depart the orbiting laboratory at which point it will burn up in the Earth’s atmosphere. This spacecraft is named the S.S. Richard “Dick” Scobee after the former NASA astronaut.

      NASA’s Artemis II SLS (Space Launch System) rocket poised to send four astronauts from Earth on a journey around the Moon next year may appear identical to the Artemis I SLS rocket. On closer inspection, though, engineers have upgraded the agency’s Moon rocket inside and out to improve performance, reliability, and safety.
      SLS flew a picture perfect first mission on the Artemis I test flight, meeting or exceeding parameters for performance, attitude control, and structural stability to an accuracy of tenths or hundredths of a percent as it sent an uncrewed Orion thousands of miles beyond the Moon. It also returned volumes of invaluable flight data for SLS engineers to analyze to drive improvements.
      Teams with NASA’s Exploration Ground Systems integrate the SLS (Space Launch System) Moon rocket with the solid rocket boosters onto mobile launcher 1 inside High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in March 2025. Artemis II is the first crewed test flight under NASA’s Artemis campaign and is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.NASA/Frank Michaux For Artemis II, the major sections of SLS remain unchanged – a central core stage, four RS-25 main engines, two five-segment solid rocket boosters, the ICPS (interim cryogenic propulsion stage), a launch vehicle stage adapter to hold the ICPS, and an Orion stage adapter connecting SLS to the Orion spacecraft. The difference is in the details.
      “While we’re proud of our Artemis I performance, which validated our overall design, we’ve looked at how SLS can give our crews a better ride,” said John Honeycutt, NASA’s SLS Program manager. “Some of our changes respond to specific Artemis II mission requirements while others reflect ongoing analysis and testing, as well as lessons learned from Artemis I.”
      Engineers have outfitted the ICPS with optical targets that will serve as visual cues to the astronauts aboard Orion as they manually pilot Orion around the upper stage and practice maneuvers to inform docking operations for Artemis III.
      The Artemis II rocket includes an improved navigation system compared to Artemis I.  Its communications capability also has been improved by repositioning antennas on the rocket to ensure continuous communications with NASA ground stations and the U.S. Space Force’s Space Launch Delta 45 which controls launches along the Eastern Range.
      An emergency detection system on the ICPS allows the rocket to sense and respond to problems and notify the crew. The flight safety system adds a time delay to the self-destruct system to allow time for Orion’s escape system to pull the capsule to safety in event of an abort.
      The separation motors that push the solid rocket booster away after the elements are no longer needed were angled an additional 15 degrees to increase separation clearance as the rest of the rocket speeds by.
      Additionally, SLS will jettison the spent boosters four seconds earlier during Artemis II ascent than occurred during Artemis I. Dropping the boosters several seconds closer to the end of their burn will give engineers flight data to correlate with projections that shedding the boosters several seconds sooner will yield approximately 1,600 pounds of payload to Earth orbit for future SLS flights.
      Engineers have incorporated additional improvements based on lessons learned from Artemis I. During the Artemis I test flight the SLS rocket experienced higher-than-expected vibrations near the solid rocket booster attachment points that was caused by unsteady airflow.
      To steady the airflow, a pair of six-foot-long strakes flanking each booster’s forward connection points on the SLS intertank will smooth vibrations induced by airflow during ascent, and the rocket’s electronics system was requalified to endure higher levels of vibrations.
      Engineers updated the core stage power distribution control unit, mounted in the intertank, which controls power to the rocket’s other electronics and protects against electrical hazards.
      These improvements have led to an enhanced rocket to support crew as part of NASA’s Golden Age of innovation and exploration.
      The approximately 10-day Artemis II test flight is the first crewed flight under NASA’s Artemis campaign. It is another step toward new U.S.-crewed missions on the Moon’s surface that will help the agency prepare to send the first astronauts – Americans – to Mars.

      Technicians completed integrating NASA’s Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow-On Lagrange 1 (SWFO-L1) satellite to an Evolved Expendable Launch Vehicle Secondary Payload Adapter ring at the Astrotech Space Operations Facility near NASA’s Kennedy Space Center in Florida on Sept. 4.
      Integrating the rideshares to the ring precedes the next prelaunch launch milestone: attaching NASA’s IMAP (Interstellar Mapping and Acceleration Probe) heliosphere mapping observatory to a payload adapter that connects to the ring. This configuration allows all three spacecraft to launch atop a single SpaceX Falcon 9 rocket, maximizing efficiency by sharing the ride to space.
      The Carruthers observatory will capture light from Earth’s geocorona, the part of the outer atmosphere that emits ultraviolet light. The observations will advance our understanding of space weather, planetary atmospheric evolution, and the long-term history of water on Earth.
      The SWFO-L1 satellite will keep a watchful eye on the Sun and the near-Earth environment for space weather activity. It is the first NOAA satellite designed specifically for and fully dedicated to continuous space weather observations. It will serve as an early warning beacon for destructive space weather events that could impact our technological dependent infrastructure and industries.
      The spacecraft will launch together aboard a SpaceX Falcon 9 rocket no earlier than 7:32 a.m. EDT on Tuesday, Sept. 23, from Launch Complex 39A at NASA Kennedy.

      From left to right, NASA’s Carruthers Geocorona Observatory, IMAP (Interstellar Mapping and Acceleration Probe), and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On-Lagrange 1 (SWFO-L1) missions will map our Sun’s influence across the solar system in new ways. Credit: NASA NASA will provide live coverage of prelaunch and launch activities for an observatory designed to study space weather and explore and map the boundaries of our solar neighborhood.
      Launching with IMAP (Interstellar Mapping and Acceleration Probe) are two rideshare missions, NASA’s Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On-Lagrange 1 (SWFO-L1), both of which will provide insight into space weather and its impacts at Earth and across the solar system.
      Liftoff of the missions on a SpaceX Falcon 9 rocket is targeted for 7:32 a.m. EDT, Tuesday, Sept. 23, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Watch coverage beginning at 6:40 a.m. on NASA+, Amazon Prime, and more. Learn how to watch NASA content through a variety of platforms, including social media.
      The IMAP spacecraft will study how the Sun’s energy and particles interact with the heliosphere — an enormous protective bubble of space around our solar system — to enhance our understanding of space weather, cosmic radiation, and their impacts on Earth and human and robotic space explorers. The spacecraft and its two rideshares will orbit approximately one million miles from Earth, positioned toward the Sun at a location known as Lagrange Point 1.
      NASA’s Carruthers Geocorona Observatory is a small satellite that will observe Earth’s outermost atmospheric layer, the exosphere. It will image the faint glow of ultraviolet light from this region, called the geocorona, to better understand how space weather impacts our planet. The Carruthers mission continues the legacy of the Apollo era, expanding on measurements first taken during Apollo 16.
      The SWFO-L1 spacecraft will monitor space weather and detect solar storms in advance, serving as an early warning beacon for potentially disruptive space weather, helping safeguard Earth’s critical infrastructure and technological-dependent industries. The SWFO-L1 spacecraft is the first NOAA observatory designed specifically for and fully dedicated to continuous, operational space weather observations.

      A SpaceX Falcon 9 rocket carrying Northrop Grumman’s Cygnus XL spacecraft is launched on NASA’s Northrop Grumman Commercial Resupply Services 23 mission to the International Space Station on Sunday, Sept. 14, 2025.Credit: NASA NASA is sending more science, technology demonstrations, and crew supplies to the International Space Station following the successful launch of the agency’s Northrop Grumman Commercial Resupply Services 23 mission, or Northrop Grumman CRS-23.
      The company’s Cygnus XL spacecraft, carrying more than 11,000 pounds of cargo to the orbiting laboratory, lifted off at 6:11 p.m. EDT Sunday on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. This mission is the first flight of the larger, more cargo-capable version of the solar-powered spacecraft. 
      Cygnus XL is scheduled to be captured at 6:35 a.m. on Wednesday, Sept. 17, by the Canadarm2 robotic arm, which NASA astronaut Jonny Kim will operate with assistance from NASA astronaut Zena Cardman. Following capture, the spacecraft will be installed to the Unity module’s Earth-facing port for cargo unloading.
      The resupply mission is carrying dozens of research experiments that will be conducted during Expedition 73, including 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.
      These are just a sample of the hundreds of scientific investigations conducted aboard the station in the areas of biology and biotechnology, Earth and space science, physical sciences, as well as technology development and demonstrations. For nearly 25 years, NASA has supported a continuous U.S. human presence aboard the orbiting laboratory, where astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including Artemis missions to the Moon and American astronaut missions to Mars.
      NASA’s arrival, capture, and installation coverage are as follows (all times Eastern and subject to change based on real-time operations):
      Wednesday, Sept. 17
      5 a.m. – Arrival coverage begins on NASA+, Amazon Prime, and more.
      6:35 a.m. – Capture of Cygnus XL with the space station’s robotic arm.
      8 a.m. – Installation coverage begins on NASA+, Amazon Prime, and more.
      All coverage times are estimates and could be adjusted based on operations after launch. Follow the space station blog for the most up-to-date information.
      Cygnus XL is scheduled to remain at the orbiting laboratory until March 2026, before it departs and disposes of several thousand pounds of trash through its re-entry into Earth’s atmosphere, where it will harmlessly burn up. The spacecraft is named the S.S. William “Willie” C. McCool, in honor of the NASA astronaut who perished in 2003 during the space shuttle Columbia accident.
