SpaceX’s next cargo mission to the ISS has a new date announced

Originally scheduled for last Friday (10), the launch of SpaceX’s 25th Commercial Resupply Service (CRS-25) mission to the International Space Station (ISS) is scheduled to take place on the last Tuesday in June (28), according to the memo. NASA official.

According to the release, the time for the event, which will be held at Launch Complex 39A (LC-39A) at the agency’s Kennedy Space Center in Florida, has yet to be set, due to “pending variables.” , including availability in the East Strip. and space station programming.

According to the agency, the delay is related to the leak of a highly toxic liquid propellant called methylhydrazine, used in the Dragon capsule’s thrusters. While fueling the spacecraft for launch, technicians noticed high levels of hydrazine vapor in part of the Draco system.

First used in a 2010 launch, the Draco system was designed by SpaceX, which is also responsible for manufacturing the thrusters. The second stage of the Falcon 9 rocket is equipped with four of them, to control the orientation of the launcher. The Dragon spacecraft uses between 12 and 18 Draco thrusters for attitude control and orbital maneuvers (such as orbit switching and atmospheric re-entry activation).

The unmanned Dragon capsule tasked with sending more than two tons of cargo to the orbital lab will launch atop a Falcon 9 rocket, the first stage of which will perform a vertical landing on one of SpaceX’s strategically-placed landing rafts. positioned in the Atlantic Ocean.

In addition to equipment and supplies for members of Number 67, the CRS-25 mission will lead to a variety of experiments to be conducted. Science headed to this mission’s orbital laboratory includes investigations into the global composition of Earth’s dust and its effects on climate, ways to build extraterrestrial habitats with space resources, human healing in space, and aging. of the immune system.

The set of experiments also includes a study of how communities of microorganisms in soil are affected by microgravity and winning research from the 9th edition of the Genes in Space program, a partnership between NASA and institutions educational institutions to encourage careers in STEM (science, technology, engineering and mathematics).
