Expedition 59 FLOWN ISS cover – Christina Koch - AIEP COA

Expedition 59 — ISS-Flown Cover Postmarked in Orbit and Signed by Christina Koch - Igor Rodin AIDEP COA !

An exceptional cover flown aboard the International Space Station during Expedition 59, postmarked in orbit on May 29, 2019, and featuring the signature of record-setting NASA astronaut Christina Koch.

The onboard cancellation dates the cover to the opening months of Koch’s first spaceflight—a mission that would ultimately become one of the most important long-duration expeditions ever completed by a female astronaut.

Christina Koch’s record-setting ISS mission

Christina Koch launched aboard Soyuz MS-12 on March 14, 2019, together with NASA astronaut Nick Hague and Roscosmos cosmonaut Alexey Ovchinin. She joined Expedition 59 as a flight engineer and subsequently remained aboard the station through Expeditions 60 and 61. NASA lists the Expedition 59 crew as:

• Oleg Kononenko — Expedition commander
• Anne McClain — NASA flight engineer
• David Saint-Jacques — Canadian Space Agency flight engineer
• Alexey Ovchinin — Roscosmos flight engineer
• Nick Hague — NASA flight engineer
• Christina Koch — NASA flight engineer

Koch’s originally scheduled stay was extended, and she ultimately spent 328 consecutive days in space, setting the record for the longest single spaceflight by a woman. During that mission, she orbited Earth 5,248 times and travelled approximately 139 million miles.

A date connected with Expedition 59 operations

The cover was postmarked aboard the ISS on May 29, 2019, while the full six-member Expedition 59 crew was living and working aboard the station.

That date also coincided with a Russian spacewalk by commander Oleg Kononenko and flight engineer Alexey Ovchinin. The two cosmonauts spent 6 hours and 1 minute outside the station conducting maintenance and scientific work.

The precisely dated onboard cancellation therefore places this cover within an active day of Expedition 59 operations and provides a direct postal record of its presence aboard the orbiting laboratory.

Christina Koch and spacewalking history

Only two months before this cover was cancelled, Koch completed her first spacewalk with Nick Hague on March 29, 2019. Later that year, she and NASA astronaut Jessica Meir conducted the first all-woman spacewalk in history on October 18.

Koch and Meir subsequently completed two additional spacewalks together, making Koch a central figure in one of the defining milestones for women in human spaceflight.

Her record-setting mission also generated valuable scientific data concerning the physical and psychological effects of extended life in microgravity, contributing to preparations for future long-duration expeditions beyond low-Earth orbit.

From Expedition 59 to lunar exploration

Koch’s career later extended beyond the International Space Station when she served as a mission specialist for Artemis II, NASA’s first crewed Artemis flight. Her selection connected the experience gained during her 328-day ISS expedition with the next generation of human exploration beyond low-Earth orbit.

This cover was postmarked early in the mission that established Koch as one of the leading explorers of her generation—before her endurance record, historic all-woman spacewalks and later participation in lunar exploration.
