Source-derived summary

STS-123 was a Space Shuttle mission to the International Space Station (ISS) which was flown by Space Shuttle Endeavour. STS-123 was the 1J/A ISS assembly mission. The original launch target date was February 14, 2008, but after the delay of STS-122, the shuttle was launched on March 11, 2008. It was the twenty-fifth shuttle mission to visit the ISS, and delivered the first module of the Japanese laboratory, Japanese Experiment Module (Kibō), and the Canadian Special Purpose Dexterous Manipulator, (SPDM) Dextre robotics system to the station. The mission duration was 15 days and 18 hours, and it was the first mission to fully utilize the Station-to-Shuttle Power Transfer System (SSPTS), allowing space station power to augment the shuttle power systems. The mission set a record for a shuttle's longest stay at the ISS.

Crew

Mission payloads

STS-123 delivered the pressurized section of the Japanese Experiment Logistics Module (ELM-PS) as well as the Special Purpose Dexterous Manipulator (SPDM) to the International Space Station. The SPDM was delivered disassembled on a Spacelab Pallet (SLP) and assembled during three spacewalks once it was at the station.

Shuttle processing

In August 2007, STS-123 crew members participated in crew equipment interface tests for the ELM-PS at Kennedy Space Center. Processing continued on schedule for Endeavour's launch in early 2008. NASA engineers applied the same ECO sensor modifications used on STS-122's external tank, to Endeavour's tank.

Editorial summary

“STS-123” enters the record as human spaceflight. Crown Archives preserves that source wording while asking what STS-123, human and spaceflight can confirm, complicate or overturn.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2008, 2007—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around STS-123, human and spaceflight.
Editorial analysis

Why this record matters

“STS-123” is worth following because a concise public description often conceals a longer documentary argument. Here, STS-123, human and spaceflight provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q534963. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2008 and 2007.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
