Mars Express, though, has extremely low fuel reserves. Low propellant level is not the largest immediate danger for Mars Express, it's a bureaucratic one, Mars Express is still slated for termination at the end of 2022, the decision for an extension into 2023-2025 - awaited early next year - "is NOT granted". [Edit] Regarding the propellant issue: "The fuel is still a (literal) unknown quantity since, in the worst case, it should have run out in 2016. But Mars Express keeps on ticking, and Godfrey, using Venus Express as a model, reckoned that there was a chance that what is left (possibly 5.6kg) might last until 2035."

What space probes are still active that are older than MODY? The two Voyagers, of course. In Earth orbit, or at an Earth Lagrange point, we have Hubble (1990), Geotail (1992), Wind (1994), SOHO (1995), ACE (1997), Chandra (1999), Landsat 7 (1999), Terra (1999), XMM-Newton (1999) and Cluster II (2000). However, I'm pretty sure that MODY is now the third oldest active human spacecraft outside Earth orbit. Five (!) years later... Geotail -- gone. It was decommissioned in November 2022, after its data recorder stopped working. Wind is still going strong and should be good for years to come. SOHO is still going. ACE is still going though it may be running out of propellant soon. Chandra, still going. Landsat 7 -- gone. It was decommissioned in 2021. Terra ate a budget cut but is still going. Decommission is expected no later than 2026. XMM-Newton, still going and fully funded through the end of FY 2026. Cluster II, still going and funded through the end of FY 2024. Along with the two Voyagers, these seven spacecraft are the Elders, the active survivors of the previous century. Are there any others from 2000 or before still operational? |
