Indigenous representatives from across the Amazon met with geographers seeking to better understand how climate change is affecting the region.

Space botany and eye checks were at the top of the research schedule aboard the International Space Station on Wednesday. Life support system upgrades also continued during the middle of the week for the Expedition 67 crew members. Understanding how plants and humans are affected by long-term exposure to microgravity is key to prolonging mission …

After standing down on the Artemis I launch attempt Saturday, Sept. 3 due to a hydrogen leak, teams have decided to replace the seal on an interface, called the quick disconnect, between the liquid hydrogen fuel feed line on the mobile launcher and the Space Launch System (SLS) rocket while at the launch pad. Performing the work at …

Payloads: Fluid Dynamics in Space (FLUIDICS): FLUIDICS session 13, runs 2 and 3, were performed by a crewmember. The measurement of liquid displacement within a sphere in microgravity relates to a given kinematic representation of a spacecraft’s fuel tank. The FLUIDICS investigation evaluates the Center of Mass (CoM) position regarding a temperature gradient on a …

Life support and computer maintenance filled the Expedition 67 crew schedule on Tuesday following a busy Labor Day aboard the International Space Station. The station’s four astronauts focused on a variety of biology and physics research on the U.S. holiday as they photographed growing vegetables and explored how fuel behaves in space. In the orbiting …

After standing down on today’s Artemis I launch attempt when engineers could not overcome a hydrogen leak in a quick disconnect, an interface between the liquid hydrogen fuel feed line and the Space Launch System (SLS) rocket, mission managers met and decided they will forego additional launch attempts in early September. Over the next several …

The launch director waived off today’s Artemis I launch attempt at approximately 11:17 a.m. EDT. Teams encountered a liquid hydrogen leak while loading the propellant into the core stage of the Space Launch System rocket.  Multiple troubleshooting efforts to address the area of the leak by reseating a seal in the quick disconnect where liquid …

After the third troubleshooting attempt, the liquid hydrogen leak has occurred again. Teams are discussing next steps.

After warming up the area of the liquid hydrogen leak, engineers are once again flowing liquid hydrogen to the core stage.

Engineers are continuing troubleshooting efforts to address a liquid hydrogen leak in a cavity in the quick disconnect where the flight side and ground side plates join. They once again will attempt to warm up the quick disconnect to try to reset the seal. The liquid oxygen tank of the core stage is full and …
