I'm trying to make a list of the 10 oldest active space probes.
-- Must be a probe (including telescopes and other scientific instruments) not a comsat -- Must be "active", meaning it's still using power, sending data back, and carrying out a mssion. Here's my first list: 1. Voyager 1 2. Voyager 2 3. Wind (1994) 4. SOHO (1995) 5. ACE (1997) 6. Chandra (1999) 7. Terra (1999) 8. XMM-Newton (1999) 9. Cluster II (2000) 10. Mars Odyssey (2001) So: is this a reasonably correct / accurate list? Have I missed anything? Many thanks in advance -- |

Depends on your definition of "probe". I personally wouldn't count any Earth orbiter and not any Earth-observing satellite. If you allow Earth orbiters, why count Chandra and not HST?

Tiny quibble, Voyager 2 launched first and has therefore been 'active' longer than Voyager 1 and so takes the laurels by a couple of weeks.
