Europe inaugurates ExoMars control center

The Europe Space Agency yesterday inaugurated the control center where it will control and download data from the ExoMars rover, Rosalind Franklin, scheduled to launch to Mars in the summer of 2020.

The control center also includes a dirt filled enclosure where they can simulate Martian conditions with a rover model.

The article outlined the project’s upcoming schedule:

Over the summer the rover will move to Toulouse, France, where it will be tested in Mars-like conditions. At the end of the year Rosalind Franklin will travel to Cannes to meet the landing and carrier modules for final assembly.

As I noted yesterday in my most recent rover update, this assembly, only six months before launch, gives them very little margin. If there are any problems during assembly, they will likely miss the 2020 launch window.

I also wonder if this will allow them any time to do acoustical and environmental testing, as was just completed on NASA’s 2020 rover, to make sure ExoMars can survive launch, landing, and the journey to Mars. If they forego those tests, they might discover after launch that they were launching a paperweight, not an expensive planetary probe.


Trace Gas Orbiter shifts orbit to prepare for ExoMars rover arrival

Europe’s Trace Gas Orbiter, in orbit around Mars, is about to make the final shifts to its orbit to place it in the right position to relay communications from the ExoMars 2020 rover, Rosalind Franklin, when it land on Mars in 2020.


A gathering of dust devils

A bunch of cool images! The European Space Agency (ESA) today released more than a dozen Martian images taken by the camera on its Trace Gas Orbiter spacecraft.

In addition to a snapshot of InSight and its landing area, “The images selected include detailed views of layered deposits in the polar regions, the dynamic nature of Mars dunes, and the surface effects of converging dust devils.” The release also included images showing details of two of Mars’ giant volcanoes, Olympus Mons and Ascraeus Mons.

The image I have highlighted to the right, reduced to post here, shows a spot on Mars where for some unknown reason dust devils love to congregate.

This mysterious pattern sits on the crest of a ridge, and is thought to be the result of dust devil activity – essentially the convergence of hundreds or maybe even thousands of smaller martian tornadoes.

Below is a side-by-side comparison of this image (on the right) with a Mars Reconnaissance Orbiter (MRO) image taken in 2009 (on the left).

UK names rover for 2020 ExMars mission

The United Kingdom has named its rover for 2020 ExMars mission in honor of Rosalind Franklin, one of the scientists who contributed to the discovery of the helix structure of DNA.

Franklin is best known for her work on the X-ray diffraction images of DNA. Her data was a part of the data used to formulate Crick and Watson’s 1953 hypothesis regarding the structure of DNA. Unpublished drafts of her papers show that she had determined the overall B-form of the DNA helix. Her work supported the hypothesis of Watson and Crick and was published third in the series of three DNA Nature articles. After finishing her portion of the DNA work, Franklin led pioneering work on the tobacco mosaic and polio viruses. Franklin died from ovarian cancer at the age of 37, four years before Crick, Watson and Wilkins were awarded the Nobel Prize in 1962 for their work on DNA.

Though this isn’t entire clear from the press release, it appears that they will refer to the rover as either “Rosalind Franklin” or “Rosalind.”
