* **August 28, 2023:** The Crew-7 astronauts began their first full day of work on the ISS. They conducted a variety of tasks, including science experiments, maintenance work, and spacewalk preparations.

Here are some of the key science experiments that the Crew-7 astronauts will be conducting on the ISS:

* **The Tissue Chips in Space experiment:** This experiment will test how human tissues respond to microgravity. The astronauts will grow human tissues in miniature chips and then study how they change over time.
* **The Plant Habitat-04 experiment:** This experiment will test how plants grow in microgravity. The astronauts will grow plants in a special habitat and then study how they are affected by the space environment.
* **The Spaceborne Environmental Nanoparticle Detection experiment:** This experiment will detect and characterize nanoparticles in the space environment. The astronauts will use a special instrument to collect samples of air and dust from the ISS and then analyze them for nanoparticles.

The Crew-7 astronauts are scheduled to remain on the ISS for about six months. During their time on the station, they will conduct a variety of science experiments, maintenance work, and spacewalks. They will also help to welcome the next crew of astronauts to the station.
