Capturing the Cosmos: ISS Astronaut’s Stunning Timelapse Photos

The International Space Station (ISS) is a marvel of modern engineering, continuously orbiting Earth and providing a unique vantage point for scientific research and breathtaking photography. Recently, NASA astronaut Matthew Dominick has been sharing a series of captivating timelapse photos on social media, showcasing the dynamic life aboard the ISS and the mesmerizing views from space.

Historical Context

The ISS, a joint project involving NASA, Roscosmos, JAXA, ESA, and CSA, has been continuously inhabited since November 2000. It serves as a microgravity and space environment research laboratory where scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The station orbits Earth at an average altitude of approximately 420 kilometers (260 miles) and travels at a speed of about 28,000 kilometers per hour (17,500 miles per hour).

Astronaut Matthew Dominick’s Photographic Journey

Matthew Dominick, part of the Expedition 71 crew, has been utilizing his limited spare time to capture and share the beauty of space through his lens. His recent posts on X (formerly Twitter) include a variety of timelapse photos that highlight the movement and life aboard the ISS.

Key Highlights:

• Selfie in Motion: Dominick shared an epic selfie while moving through the U.S. Destiny module, giving a glimpse of daily life on the ISS.
• Star Trails and Solar Panels: Two notable photo stacks show star trails surrounding the ISS’s solar panels. Dominick explained the technical details, including the use of five 30-second exposures, a 24mm lens, f4 aperture, and ISO 800.
• Experimenting with Exposures: Dominick has been experimenting with different exposure times to capture the Earth and stars from the ISS. He shared images taken with ISO 6400, f1.4, and exposure times ranging from 10 seconds to 1/4 second.
• Challenges and Techniques: Dominick discussed the challenges of astrophotography at orbital speeds and the different optical qualities of ISS windows. He also mentioned using a window from the docked Boeing Starliner spacecraft for some shots.
• Mechanical Assistance: The astronaut highlighted the use of mechanical arms that clamp to parts of the ISS to hold the camera, aiding in capturing stable and clear images.
