Let’s see what it can do!
ESA put out a nice update on the ExoMars Mission.
There will be a SpaceX launch at 09:17 EST / 14:17 UTC. That’s IF all goes well. This launch was scrubbed yesterday due to winds.
I will have a live link up at 14:00 UTC / 05:00 EST.
The payload is the PAZ satellite.
There is also an a red–blue anaglyph image of Phobos composed from the stereo pair acquired by the ExoMars orbiter’s CaSSIS – you’ll need 3D glasses (or some sort of red/blue viewing device.
The ESA caption:
Colour composite of Phobos taken with the ExoMars orbiter’s Colour and Stereo Surface Imaging System (CaSSIS) on 26 November 2016. The observation was made at a distance of 7700 km and yields a resolution of 87 m/pixel.
To create the final colour image, two images were taken through each of the four colour filters of the camera – panchromatic, blue–green, red and infrared – and then stitched together and combined to produce the high-resolution composite.
Two of the colour filters used by CaSSIS lie outside the wavelength response of the human eye, so this is not a ‘true’ colour image. However, showing the data as a colour representation can reveal details of the surface mineralogy. Different colours are clearly seen, with the bluest part in the direction of the large crater Stickney, which is out of view over the limb to the left. Although the exact composition of the material is unknown, the colour differences are thought to be caused by compositional variations on scales of hundreds of metres to several kilometres.

WOW! This collection of high resolution images came from he Mars Camera, CaSSIS (Colour and Stereo Surface Imaging System) on the ExoMars Trace Gas Orbiter and are among the first to be released.
The CaSSIS was developed by a team from the University of Bern led by Prof. Nicolas Thomas from the Center of Space and Habitability

I don’t want to even consider the worst.
GOOD LUCK ExoMars!!!
How is ESA going to navigate to Mars? By using quasars of course.
Very cool!!! The inset is explained below BTW.

- In order to precisely deliver the Schiaparelli landing demonstrator module to the martian surface and then insert ExoMars/TGO into orbit around the Red Planet, it’s necessary to pin down the spacecraft’s location to within just a few hundred metres at a distance of more than 150 million km.To achieve this amazing level of accuracy, ESA experts are making use of ‘quasars’ – the most luminous objects in the Universe – as ‘calibrators’ in a technique known as Delta-Differential One-Way Ranging, or delta-DOR.Until recently, quasars were only poorly understood. These objects can emit 1000 times the energy of our entire Milky Way galaxy from a volume that it not much bigger than our Solar System, making them fearfully powerful.
Tim Peake takes control of the ESA’s Mars rover prototype named Bridget located in the UK from the International Space Station.
He controlled the rover for two hours and even drove it into a simulated cave. Nice work!
I don’t know what the odds of the rover going into a cave on Mars but I would hope they would code in a reverse route in the event radio contact was lost.
On 14 April the ExoMars switched on the camera and pointed it to the sky.
The first image taken by the Trace Gas Orbiter of the ESA–Roscosmos ExoMars 2016 mission.
The image was taken by the Colour and Stereo Surface Imaging System, CaSSIS, and points to a randomly selected portion of the sky close to the southern celestial pole.
The picture shows the result of taking one CaSSIS frame, turning the camera’s rotation mechanism, and then taking another. By subtracting the two frames, a series of bright and dark spots are seen, all equally offset from each other, demonstrating that these are positive and negative images of the same stars.
The field-of-view is 0.2º in the horizontal direction, and is a subset of a larger image, extracted for this purpose to show the stars at a reasonable size.
In operation at Mars, about 400 km above the planet, CaSSIS will sweep out a swath as TGO approaches it, then turn the rotation mechanism by 180º and image the same swath as it recedes. By doing so, CaSSIS will make stereo images of the surface.
If you’re wondering about the black spots: The picture shows the result of taking one CaSSIS frame, turning the camera’s rotation mechanism, and then taking another. By subtracting the two frames, a series of bright and dark spots are seen, all equally offset from each other, demonstrating that these are positive and negative images of the same stars.

In case you missed the ExoMars2016 launch this morning. Be sure to check the previous post before 21:29 (22:29 CET) for the first acquisition of signals from the spacecraft. So far all is well
