Source-derived summary

Soyuz MS-20 was a Russian Soyuz spaceflight to the International Space Station (ISS) on 8–20 December 2021. Unlike previous Soyuz flights to the ISS, Soyuz MS-20 did not deliver any crew members for an ISS Expedition or serve as a lifeboat for any crew members on board the station. Instead, it was commanded by a single professional cosmonaut. It carried two space tourists represented by company Space Adventures, which had executed eight space tourism missions to the ISS between 2001 and 2009. The flight to reach the ISS took six hours.

Crew

Alexander Misurkin, a veteran of two long-duration missions to the ISS, commanded the Soyuz, which was modified to allow it to be flown by a sole cosmonaut.

Backup crew

Space tourists

For some time, it was speculated that Austrian airline pilot Johanna Maislinger would be one of the tourists, but on 13 May 2021, Space Adventures confirmed that Japanese billionaire, art collector and space enthusiast Yusaku Maezawa had acquired both seats, the other for his production assistant Yozo Hirano. This was the first time two Japanese launched to space together.

In July 2021, Space Adventures Moscow Office changed their previous story and said that Maislinger had never had access to the funds she had claimed, and they had never treated her as a serious candidate.

It was also reported in April 2021 that Japanese entertainer Yumi Matsutoya was to fly on Soyuz MS-20 with Maislinger.

Editorial analysis

Why this record matters

The phrase “spaceflight mission to ISS” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 2, 2026. The linked authority identifier is Q95977777. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021, 2001 and 2009.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
