Mars Express Orbiter gets a lease of life, the mission have been extended one Martian year (23 months) from early December 2005.

Great new! Also for Marsis... smile.gif
Hoping next year they will release more imagery! rolleyes.gif

Mars Express gets a third extension, to December 31, 2009.

(And so do Venus Express and Cluster)

The Express missions may not be media stars, but it's relieving to see these rugged probes keeping our eyes open on Venus and Mars when new launches are put in jeopardy by the caprices of economy. smile.gif

That is a little bit concerning, Mars Express, together with Cluster and INTEGRAL, is slated for termination at the end of December 2022. "https://www.cosmos.esa.int/web/integral, [whatever this really means], ESA would like to engage in a creative process for these missions and develop innovative concepts that [...] would make it attractive for the SPC to re-evaluate their decision." What's funny is that the https://sci.esa.int/web/director-desk/-/extended-operations-confirmed-for-science-missions of the mission extensions fails to give a direct indication of such a severe decision.

Though I think the description of the distance from Mars Express in the article is off, surely by an order of magnitude, at least?

QUOTE
The animation is pieced together from 19 HRSC images, taken on 30 March 2022 when Phobos was 12 km away from the camera. From this perspective it is difficult to see the size difference between the martian moons, as Deimos is further from the camera at a distance of 28 km.

Certainly wrong, as Mars Express cannot get close to Deimos.

I think 12000 and 28000 km is probably right.

In regard to the last sentence of the https://www.esa.int/Science_Exploration/Space_Science/Mars_Express/Mars_and_Jupiter_moons_meet, it is important to note that Mars Express is currently only https://meetingorganizer.copernicus.org/EPSC2022/EPSC2022-1136.html, further extensions are subject to ESA budget allocations at the upcoming https://vision.esa.int/cm22/ in November 2022, which seem to be https://www.spaceintelreport.com/esas-seeking-a-big-budget-boost-from-november-ministers-meeting-but-science-increase-is-zero/ in respect to space science. From the https://meetingorganizer.copernicus.org/EPSC2022/EPSC2022-1080.html, Mars Express is still going strong and an extension of operations even into the 2030s is feasible.

If I remember correctly, ExoMars is funded out of a separate category than the science program. This might mean that any plan to fly the ExoMars rover might be funded out of another pot of money.

Interesting, considering that MEPAG presentations as recent as May 2022 had basically written MEx off as a viable relay ("Fuel load extremely low and uncertain"). https://www.lpi.usra.edu/mepag/meetings/mepag-39/slides/Ianson_Meyer.pdf

They have corrected the distances of the Martian moons from Mars Express, however, I wonder if the date given for the https://www.esa.int/ESA_Multimedia/Videos/2022/10/Phobos_blocking_its_sibling_Deimos is correct. According to http://spice.esac.esa.int/webgeocalc/#AngularSeparation, the smallest angular separation of Deimos and Phobos observed by Mars Express was about 11 degree on 30 March 2022. The best opportunity in that month would have been on 6 March 2022 at around 22:47:55 UTC with a calculated angular separation between Deimos and Phobos of only about 0.016 degree. huh.gif

EDIT: A WebGeocalc http://spice.esac.esa.int/webgeocalc/#AngularSeparationFinder search gives only 3 occultations of Deimos by Phobos observable by Mars Express in 2022: on 8 April, 30 May, and 17 August. The http://spice.esac.esa.int/webgeocalc/#StateVector between Mars Express and the two moons during the 30 May occultation are in agreement with the corrected distances given in the https://www.esa.int/Science_Exploration/Space_Science/Mars_Express/Mars_and_Jupiter_moons_meet. Case closed. wink.gif

Meanwhile, the Mars Express team is https://www.scienzeplanetarie.it/2023/01/04/supporto-allestensione-della-missione-mars-express-2023-2025/ of the scientific community for the extension of the mission.

Posted by: bobik Mar 7 2023, 07:12 PM

https://sci.esa.int/web/director-desk/-/extended-life-for-esa-s-science-missions

[...] ESA's Science Programme Committee (SPC) has confirmed the continued operations of ten scientific missions in the Agency's fleet. [...] The decision was taken during the SPC meeting in Antwerp, Belgium, on 7 March. [...]

The extension of three ESA-led missions, Cluster, Integral and Mars Express, all of which have been operational since over 20 years, were in jeopardy financially, as two new major missions (JUICE and Euclid) will be joining the fleet of missions in operations this year. For all three missions, ESA received strong and well-justified requests from the scientific community to extend the missions. ESA’s scientific advisory structure (the Astronomy Working Group, the Solar System Exploration Working Group, and the Space Science Advisory Committee) reviewed the science cases and supported further limited extensions. Thanks to some significant programmatic risks (related to JUICE and Euclid) having recently been retired, the SPC agreed to extend these three missions for a limited amount of time, using part of the Programme contingency in the years 2023-2025. [...]

The science operations of Mars Express are extended until end of 2026 and the SPC also approved the indicative extension of Mars Express from 1 January 2027 to 31 December 2028, enabling support to the JAXA-led Mars Moons eXploration (MMX) mission. This will be followed by two years of post-operations; the extension to 2028 will be reviewed in 2025/2026, after MMX launch and arrival at Mars. [...]
