Key Concepts and Definitions
Astronaut
An astronaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. ESA astronauts undergo rigorous training and preparation before embarking on missions.
Comets
Comets are celestial objects composed of ice, dust, and rocky material. They originate from the outer parts of our solar system and become visible when they approach the Sun, developing a glowing coma and tail. The Rosetta mission, for example, has significantly advanced our understanding of these celestial wanderers.
Space Debris
Space debris refers to defunct human-made objects in orbit around Earth, such as decommissioned satellites and spent rocket stages. Clean space initiatives aim to mitigate the accumulation of this debris to maintain a viable orbital environment for future missions.

Life on the ISS
Daily Routine
Living on the ISS requires strict adherence to schedules and routines. Astronauts divide their time between conducting experiments, maintaining the station, and physical exercise to counteract the effects of microgravity.
Scientific Research
The ISS serves as a microgravity laboratory where researchers conduct experiments that are impossible on Earth. These studies span a wide range of fields, from fundamental physics to advanced medical research.
Rosetta and Philae
The Landing
One of the most thrilling events in recent space exploration history was Philae’s landing on Comet 67P. The landing was a complex maneuver that required precise calculations and impeccable execution.
Significant Discoveries
The data collected by Rosetta and Philae has led to numerous discoveries, including the detection of organic molecules on the comet’s surface, which are essential for understanding the origins of life.
Mars Express: Longevity and Achievement
High-Resolution Imaging
Mars Express’s stereo camera has provided some of the most detailed images of Mars, offering insights into the planet’s geology and climate history.
Water Discovery
One of the most groundbreaking findings was the detection of liquid water beneath the Martian surface. This discovery has significant implications for the possibility of life on Mars and future human missions.
