A space history mystery: What happened to the Viking arm used 50 years ago?

I appreciate the task, but I notice the original text you've provided is incomplete—it only says "A timely tale about a 50-year-old robotic arm..." without the actual content to rewrite.

To properly apply the NobsFacts standards, I need the full original article text. Could you provide the complete article so I can:

- Strip opinion framing ("timely tale," narrative language)

- Identify and preserve named individuals, dates, locations, and verifiable facts

- Remove speculation and unnamed sources

- Present the factual record about the Viking arm's history and current status

Once you share the full text, I'll rewrite it as strict fact-based reporting.
