Voyager 1’s cost is usually given as part of the Voyager 1 and 2 mission budget, which NASA says was about $865 million for spacecraft development, launch, and mission operations through the Neptune encounter. NASA also notes an additional $30 million was added for two more years of mission support after that phase.

Quick Scoop

  • Main mission cost: about $865 million for Voyager 1 and 2 together.
  • Extra post-Neptune funding: $30 million.
  • Why the number is shared: Voyager 1 was flown as part of the twin Voyager program, so the public cost is usually reported for both spacecraft together rather than one alone.

What that means

If someone asks “how much did Voyager 1 cost to make,” the most accurate public answer is that the Voyager program cost about $865 million total , not a neatly separated Voyager 1-only manufacturing price. In practice, that figure covers development, launch, and mission operations, so it is better thought of as the mission’s total price tag than just the hardware build cost.

TL;DR

About $865 million for Voyager 1 and 2 combined, plus $30 million more for extended support.
