Engineers for NASA's Mars Odyssey mission are examining data from the orbiter to determine whether onboard backup systems never used by the 6-year-old spacecraft could still be available if needed. Odyssey reported last week that a power processing component of the backup, or "B-side," systems had stopped working. The component, the high-efficiency power supply, has a twin that is continuing to serve the "A-side" hardware, which is operating normally. Odyssey has stayed on its A-side systems, including the A-side flight computer, since launch on April 7, 2001. However, the A-side power supply cannot serve most systems on the B-side, including the backup B-side computer. If engineers do not determine a way to restore the B-side power supply, most of the backup hardware would not be available, if it were ever needed. Odyssey is in its second extended mission. The orbiter is conducting scientific observations and also serving as the primary communications relay for NASA's Mars rovers. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Odyssey Project for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, is the prime contractor for the project and built the spacecraft. I hope Odyssey is not one failure away from another MGS-type loss because of this. |

ODY's 15th anniversary of entering Mars orbit passed unnoticed last month. Next milestone: in February 2017, the 15th anniversary of the beginning of its science mission.

ODY's 15th anniversary of entering Mars orbit passed unnoticed last month. Next milestone: in February 2017, the 15th anniversary of the beginning of its science mission. 17 years since arrival at Mars. 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. Doug M. |

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? |
