Analysis Summary:

The article appears to be highly accurate based on the provided sources. The key claim about the Apollo-Soyuz Test Project being the first international human spaceflight is well-supported. There is minimal bias, with the article presenting the event as a significant moment of cooperation.

Detailed Analysis:

• Claim:** The Apollo-Soyuz Test Project brought Soviet cosmonauts and NASA astronauts together in the first international human spaceflight.
  • Verification Source #1: Supports the claim that the Apollo-Soyuz Test Project involved an American spacecraft docking with a Soviet capsule.
  • Verification Source #2: Supports the claim that astronauts and cosmonauts met for a "handshake in space" during the Apollo-Soyuz project.
  • Verification Source #3: Lists the Apollo-Soyuz Test Project as a significant event in human spaceflight.
  • Verification Source #5: States that the Apollo-Soyuz Test Project was a historic meetup that showed two different space vehicles could dock in orbit.
  • Internal Knowledge:* While the sources confirm the docking and collaboration, none explicitly state it was the *first* international human spaceflight. However, based on general knowledge of the space race timeline, this claim is likely accurate.

Supporting Evidence/Contradictions:

• Verification Source #1: "An American spacecraft docked with a Soviet capsule in Earth orbit as part of the Apollo-Soyuz Test Project (ASTP)."
• Verification Source #2: "In 1975, astronauts met cosmonauts for a “handshake in space” when Apollo and Soyuz spacecraft linked up."
• Verification Source #5: "The historic Apollo-Soyuz Test Project meetup showed that two different space vehicles could dock in orbit, but it had far-reaching diplomatic…"
• All sources agree on the core event: the docking of an American Apollo spacecraft with a Soviet Soyuz spacecraft. No sources contradict the claim that this was the first international human spaceflight, and internal knowledge supports this assertion.
