SpaceX is preparing to launch its Crew-7 Mission to the International Space Station (ISS) this week. The mission will transport four individuals who will continue ongoing research aboard the orbital lab. The launch is scheduled for August 25, at 3:49 a.m. EDT.

Crew-7 consists of representatives from four different space agencies: NASA, ESA, JAXA, and Roscosmos. The team’s stay on the ISS will overlap with SpaceX’s Crew-6 mission for approximately one week, as members from the Crew-6 mission return to Earth.

During their time on the ISS, Crew-7 will be involved in over 200 science investigations. These investigations will cover a wide range of topics, including studies on microorganism samples on the exterior of the space station, the effects of microgravity on sleep cycles, microbial growth on stainless steel surfaces, and tracking astronauts’ physical and psychological responses in space.

One of the investigations, the ISS External Microorganisms study, will examine samples released from the station’s life-support systems to analyze their DNA and determine the variety and distance traveled by microorganisms in the vacuum of space. This information will help scientists understand how these microorganisms behave in simulated environments on the moon and Mars.

Another study, the Bacterial Adhesion and Corrosion investigation, will focus on studying biofilms on stainless steel surfaces in the ISS’s water systems. Understanding how biofilms accumulate and corrode these surfaces will help improve sanitation protocols for long-duration spaceflights.

The Sleep in Orbit study aims to measure brain activity during sleep onboard the ISS. Using a novel electroencephalogram (EEG) that fits in the ear, researchers will compare sleep patterns and brain activity of astronauts in space with those on Earth. This research will help develop strategies to improve sleep quality and overall well-being during space missions.

The Crew-7 mission is an essential part of ongoing research to understand the effects of space travel on the human body. Maintaining bone density, muscle mass, and overall health during extended periods in microgravity is crucial for the success of future deep-space missions. The Complement of Integrated Protocols for Human Exploration Research (CIPHER) is a set of 14 experiments within this mission that aims to examine the effects of extended time in space and develop methods to mitigate the body’s reaction to microgravity.

Overall, SpaceX’s Crew-7 mission will contribute to advancing our understanding of space travel and provide valuable insights for future missions to the moon, Mars, and beyond.
