Mission Teams Target Tuesday for Launch of Cygnus Cargo Mission

The Cygnus cargo craft approaches the International Space Station on Aug. 4 while orbiting 261 miles above the coast of the Garabogazköl Basin in Turkmenistan.

Today, NASA, Northrop Grumman, and SpaceX confirmed joint teams are targeting 12:07 p.m. EST on Tuesday, Jan. 30 for Falcon 9 to launch the 20th Northrop Grumman commercial resupply services mission to the International Space Station.

SpaceX’s Falcon 9 rocket and Northrop Grumman’s Cygnus resupply spacecraft will lift off from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida to deliver more than 8,200 pounds of science investigations, supplies, and equipment to the orbiting laboratory. Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron are currently predicting an 95% chance of favorable weather conditions for launch. The primary weather concerns for the launch area are the cumulus cloud rule.

NASA and Sierra Space are preparing for the first flight of the company’s Dream Chaser spacecraft to the International Space Station. Dream Chaser and its companion cargo module, called Shooting Star, arrived at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, for environmental testing, scheduled to start in mid-December, ahead of its first flight, scheduled for the first half of 2024.

The Neil Armstrong Test Facility, part of NASA’s Glenn Research Center in Cleveland, is home to multiple test facilities, including the Space Environments Complex and the In-Space Propulsion Facility, both stops for Dream Chaser. The complex is home to the Mechanical Vibration Facility, which subjects test articles to the rigorous conditions of launch.

While at Armstrong, the Dream Chaser winged spacecraft will be stacked atop its Shooting Star cargo module on the vibration table to experience vibrations like those during launch and re-entry to the Earth’s atmosphere.

Following vibration testing, Dream Chaser will be moved to the propulsion facility for thermal vacuum testing. Dream Chaser will be placed in a vacuum and exposed to low ambient pressures, low-background temperatures, and replicated dynamic solar heating, which simulates the environment the spacecraft will encounter during its mission. This facility is the only one capable of testing full-scale, upper stage rockets and rocket engines under simulated space conditions and conducting altitude hot fire.

After completion of testing at Armstrong, Dream Chaser will be shipped to NASA’s Kennedy Space Center in Florida for further launch preparations, currently scheduled for liftoff in the first half of 2024.

Meteorologists with Cape Canaveral Space Force Station’s 45th Weather Squadron are calling for 100% favorable weather conditions for launch of tonight’s SpaceX 29th commercial resupply services mission for NASA to the International Space Station.

SpaceX’s Falcon 9 rocket, with the Dragon spacecraft atop, is targeted to lift off from Kennedy’s Launch Complex 39A. The instantaneous launch window is at 8:28 p.m. EST.

Our live broadcast begins at 8 p.m. – watch on NASA Television, the NASA app, YouTube, and on the agency’s website, or get live updates here on the blog.

SpaceX CRS-26: Scrubbed; NASA, SpaceX Now Targeting Nov. 26 for Launch

Due to poor weather conditions in the area along Florida’s Space Coast for today’s planned launch of SpaceX’s 26th commercial resupply services mission to the International Space Station, SpaceX and NASA now are targeting liftoff for 2:20 p.m. EST Saturday, Nov. 26, from the agency’s Kennedy Space Center in Florida. Launch coverage will begin at 2 p.m. EST on NASA TV, the agency’s website, and the NASA app.

A launch Saturday would lead to docking Sunday, Nov. 27, for the Dragon to deliver important research, crew supplies and hardware to the crew aboard the orbiting laboratory. Docking coverage will begin at 6 a.m. with the spacecraft planned to arrive at the space station around 7:30 a.m.
