Dream Chaser spacecraft

The collaboration between NASA and Sierra Space is progressing smoothly with the Dream Chaser spacecraft’s initial voyage to the International Space Station. This unmanned cargo spacecraft is set for a demonstration flight in 2024, as a key part of NASA’s commercial resupply services initiative. This development was shared by Sierra Space.

At the Neil Armstrong Test Facility, NASA and Sierra Space are dedicated to the Dream Chaser spacecraft’s testing, emphasizing environmental simulations for its forthcoming mission to the ISS. Following these tests, the spacecraft will be transferred to the Kennedy Space Center for its 2024 launch.

In preparation for Dream Chaser’s inaugural flight to the ISS, NASA and Sierra Space are moving forward with the Dream Chaser and its accompanying cargo module, named Shooting Star. These arrived at the Neil Armstrong Test Facility in Sandusky, Ohio, for crucial environmental testing, set to commence in mid-December, in anticipation of its maiden flight in the first half of 2024.

Advanced Testing Facilities at NASA

The Neil Armstrong Test Facility, a segment of NASA’s Glenn Research Center in Cleveland, encompasses various testing areas. This includes the Space Environments Complex and the In-Space Propulsion Facility, which are integral to Dream Chaser’s testing. The facility also houses the Mechanical Vibration Facility, designed to expose test articles to intense launch conditions.

During its time at the Armstrong facility, the Dream Chaser spacecraft, equipped with wings, will be mounted on top of the Shooting Star cargo module on a vibration table. This setup will simulate the vibrations experienced during launch and re-entry into Earth’s atmosphere.

NASA and Sierra Space are moving steadily towards the inaugural flight of the Dream Chaser spacecraft to the ISS. This uncrewed cargo spacecraft is scheduled for a demonstration mission in 2024, aiming to contribute to NASA’s commercial resupply services.

Thorough Space Simulation

Post-vibration tests, the Dream Chaser will be relocated to the propulsion facility for thermal vacuum testing. Here, it will undergo exposure to vacuum conditions, low ambient pressures, chilling background temperatures, and simulated dynamic solar heating. This replicates the conditions the spacecraft will face during its mission. This facility is unique in its ability to test full-scale upper stage rockets and rocket engines in simulated space conditions, including altitude hot fire tests.

Once the testing phase at Armstrong is complete, Dream Chaser will be transported to NASA’s Kennedy Space Center in Florida for additional launch preparations, with a scheduled launch in the first half of 2024.

isn’t it too early to talk about 2024 flights, we don’t know if they’ll make it on time or not
