During the first week on the Station, Alexander and the new arrivals will familiarise themselves with their new home before beginning a full roster of research and technical activities.
Alexander's 166-day mission is called Blue Dot after the American astronomer
The mission includes an extensive scientific programme, reflecting the diversity of research conducted on the Station.
In keeping with ESA's policy of maximising the practical benefit of research in space, more than 40 experiments are of scientific value or will prepare for further exploration missions.
Experiments will cover materials physics, human physiology, radiation biology, solar research, biotechnology, fluid physics and astrophysics, in addition to a series of technology demonstrations.
A highlight of Blue Dot is the electromagnetic levitator furnace, intended to improve industrial casting processes and permit finer and more delicate metal castings.
By suspending molten metal in weightlessness, scientists can obtain much more precise measurements of metal characteristics than possible on Earth, where the readings are typically affected by the container.
All scientific experiments on the
As a flight engineer, Alexander will also help to dock ESA's fifth and final Automated Transfer Vehicle,Georges Lemaitre, which is set for launch on 25 July.
These ATVs are the largest supply vessels serving the Station, delivering essential cargo, performing regular orbit reboosts and capable of manoeuvring the 420-tonne complex out of the way of hazardous space debris if need be.
ATV-5 will test the new LIRIS laser infrared imaging sensor that will allow future vessels to dock with targets such as space capsules and orbital debris.
Alexander will also be closely involved in berthing other supply vessels expected to arrive during his mission.
Further highlights of the mission include a planned spacewalk.
Like other ESA astronauts before him, Alexander will also conduct an educational programme to inspire children.
