Samantha Cristoforetti returns to Earth along with Terry Virts, Anton Shkaplerov

Samantha Cristoforetti, the seventh ESA astronaut and first female astronaut to have completed a long mission in space, has returned to Earth along with NASA astronaut Terry Virts and Russian commander Anton Shkaplerov on June 11 by landing safely in the Kazakh steppe after a three-hour ride in their Soyuz spacecraft.

The astronauts left the International Space Station at 10:20 GMT at the end of their six-month stay on the research complex leaving behind NASA astronaut Scott Kelly and cosmonauts Mikhail Kornienko and Gennady Padalka to look after the Station and run experiments.

Soyuz TMA-15M braked from the Station’s cruising speed of almost 28 800 km/h and entered the atmosphere shortly afterwards. The small descent module separated as planned and parachutes deployed to slow the vehicle down even more. The module fired retrorockets moments before landing and springs in the moulded seats reduced the impact of hitting the steppe at 13:44 GMT. Teams were on hand within minutes to help them out.

Samantha has set new records for longest single time in space for an ESA astronaut and female astronauts in general. She took over duties from ESA astronaut Alexander Gerst for cargo on ESA’s Automated Transfer Vehicle Georges Lemaître. Samantha was responsible for packing the versatile spacecraft. She monitored its undocking, which marked the end of an era – Georges Lemaître was the last in a series of five ATV vessels supplied by ESA to service the Station.

Samantha also helped to grab and dock two Dragon ferries with the Station’s robotic arm, providing support for the first in January and taking the lead as prime operator of the 16 m-long arm to grapple Dragon-6 in April.

With two spacewalks conducted during her mission, Samantha played an important role preparing her colleagues for their sortie and supporting them while they were working outside the Station.

For the first time a Station airlock was used for scientific research when Samantha and Terry sampled their exhaled breath under reduced pressure, using nitric oxide as a tool to monitor lung inflammation as well as charting lung health in astronauts.

Samantha’s Expedition saw much research conducted on genetics and biology, keeping ants, fruit flies, plants and worms for international studies on the effects of spaceflight over multiple generations.
