Wild space ride awaits Andreas Mogensen

Astronaut Andreas Mogensen is scheduled to launch for the International Space Station on 25 August. Among other things, he will collect data for various DTU research projects, providing Danish researchers with new knowledge.

Andreas Mogensen’s journey to space

  • On launch day, a Falcon 9 booster rocket will be ready on the launch pad at the Kennedy Space Center in Florida. It is a so-called two-stage rocket, consisting of a Dragon spacecraft on top of a 70-metre-tall rocket.
  • Andreas Mogensen will be wearing a ‘pressure suit’ that will keep him alive if the pressure drops in the cabin.
  • The rocket engines are loaded with fuel. The astronauts arrive for the launch quite late. They take a ride on a small elevator up a tower to the upper Dragon capsule, which is a kind of cabin for the crew.
  • The astronauts take their places in their moulded seats. Switching seats is not an option.
  • Andreas Mogensen is the pilot of the remote-controlled spacecraft. His job is to keep an eye on everything—and to make adjustments if things do not go as planned.
  • Shortly before the launch, the control room tests all systems.
  • The nine engines on the rocket turn on and a large plume of smoke will appear. The countdown from ten starts.
  • The first stage of the rocket blasts the Falcon 9 up through Earth’s atmosphere.
  • A few minutes after the launch, the first stage of the rocket and the spacecraft separate. The rocket lands shortly afterwards on a barge in the Atlantic Ocean and will be reused.
  • The second stage, which only has one engine, now turns on, increasing the speed of the spacecraft to the one necessary for reaching Earth orbit.
  • The second stage burns out, is ejected, and burns up upon re-entry into Earth’s atmosphere.
  • The astronauts journey on in the Dragon capsule, which has steering engines and oxygen tanks. Now they need to increase the speed and get into the same trajectory as the ISS.
  • The astronauts arrive at the International Space Station after approximately 24 hours. Andreas Mogensens is responsible for docking the spacecraft safely with the space station.
  • Aboard the ISS, Andreas Mogensen will take on the role of Commander in September.
