Mars seen today

Excellent views of Mars acquired by the VMC today at 07:00 CEST (05:00 UTC), and downloaded within hours, transmitted to ESOC in Darmstadt, processed by the Mars Express team and... here it is! Thanks to the MEX team and Simon Wood.

Hot on the heels of yesterday's images, here are today's set fresh off the spacecraft; again we see possible clouds/dust round the poles.

These images were taken at an altitude of 9900 km above the surface at 07:00 CEST (5:00 UTC) this morning and transmitted back to Earth at 13:15 CEST (11:15 UTC).

This rapid turn around is in part due to the current Earth - Mars distance being 'only' 123 336 112 km. At this distance it only takes 6 mins 51 seconds for signals travel from the spacecraft to Earth. (As we get further away this can increase to up to 25 minutes.)

This proximity gives us higher data transmission rates, which mean we can transmit more of the stored data from the science instruments – and thus occasionally leaves us with spare data downlink capacity in some of our ground station passes. This spare capacity enables us to schedule the VMC data dumps much closer to the VMC observations.

Continuing from yesterday's highlighting of the Phoenix lander, here we have marked the landing site of the NASA Mars Exploration Rover B - Opportunity.

Opportunity is a fellow seasoned Martian explorer; it was launched only 5 days after Mars Express on 7 June 2003, landing on 25 January 2004 – one month after we entered Martian orbit.

This false-colour image of the interior of 'Endurance Crater' on Mars was collected on 4 August 2004 by NASA's Mars Exploration Rover Opportunity. It was relayed to Earth via ESA's Mars Express. The image, taken with the Rover's panoramic camera, was relayed to Earth by ESA's Mars Express together with other scientific data. Three separate frames, taken through red, green and blue filters, were combined to produce this colour image. NASA/JPL/Cornell

Its landing site is located in the Meridiani Planum, an area of interest due to concentrations of the mineral Hematite, which on Earth is often formed in the presence of water.

With the possibility of water-formed minerals located here, it is not surprising that this is an area also investigated by our mineralogical Spectrometer OMEGA and our high resolution camera HRSC.

As with Phoenix, its sister rover Spirit and, currently, Curiosity, Mars Express has performed communication activities with Opportunity over the years, including the relay of the image above from the surface back to Earth.

As usual, the full set of this morning's images is available in Flickr.

 

Mars seen yesterday

Today's post contributed by Mars Express operations engineer Simon Wood – Ed.

Here in our latest Mars Webcam images taken yesterday, 4 June, we have not only captured more shots of the northern polar cap and what seems to be further dust/cloud formations around the pole, we have also snapped some of the biggest geological features on the planet.

In this image, we have all three volcanoes that make up the Tharsis mountains.

These three volcanoes dwarf anything found on Earth, ranging from 14 to 18 km in height. To put this into perspective, the tallest volcano on Earth is Mauna Loa in Hawaii, which only reaches 9 km above the ocean floor.

However, the Tharsis mountains are themselves dwarfed by the largest volcano on the Red Planet (and indeed in the solar system), Olympus Mons, which has an approximate height of a staggering 25 km!

The favourable lighting conditions in yesterday's observation enabled the entire base of the volcano to be visible and if you look closely you can even make out the crater. Olympus Mons covers an area of around 300 000 square kms, which to give some indication of the scale, would cover most of France.

We also just see the edge of the 'Grand Canyon of Mars' the Valles Marineris running along the limb of the planet (hopefully we'll have more on that in a forthcoming observation).

And here's a very cool Valles Marineris fly-through video:

One further item we've tagged in our image is the landing site of NASA's Phoenix spacecraft, the first spacecraft to send back science data from the Martian poles.

In May 2008, Mars Express provided communication relay support to Phoenix using MELACOM, our UHF radio, recording its radio signal during the entry, descent and landing phase (just as we would later do for Curiosity in 2012).

Some further relay tests were performed once it was successfully on the surface, with our last contact completed on 31 May 2008.

As usual all the images are available on the VMC flickr account: http://www.flickr.com/photos/esa_marswebcam/

Our webcam views the Universe

A couple weeks, ago we ran an additional test of our long exposure settings on VMC. This time, we we upped the image exposure to 30 seconds.

Just like with our Phobos images, its best to have a target to look at and for this test we used Jupiter.

We found that, not only was Jupiter visible on just a 2-second exposure, but on the longer ones Jupiter was also visible together with the two twins of Gemini, Pollux and Castor.

So in this set we have our first image of a planet other than Mars and also our first confirmed imaging of stars!

The full image set along with all our other VMC images are in our Flickr channel.

 

 

 

 

 

Mars Full Orbit Video 2.0: Kepler rocks the Red Planet

Just in time to celebrate the 10th anniversary of Mars Express: a new and enhanced Full Orbit Video delivered by the VMC camera - the Mars Webcam!

The version below is a special 'MEX birthday preview' – we'll post a somewhat extended version late next week (along with a more detailed explanation on how this video was produced), to coincide with the next expected VMC image set arriving from Mars.

What's the 'Full Orbit video', you ask? Access the original FO video produced in 2010 for the full description.

Thanks to the Mars Express Science & Operations teams for generating a fabulous, unique-in-our-Solar-System view of the Red Planet.

Happy Birthday, Mars Express!

ESA’s Mars Express views Gale Crater

Quick update received on 11 March from Mars Express operations engineer Andy Johnstone - Ed.

We just made a very cool observation with VMC, that I've posted to the Flickr
account.

On 7 March, we were scheduled to perform a MELACOM pass with NASA's MSL; this involves us passing over Gale Crater with our MELACOM UHF antenna pointed towards the rover.

13-066_22.53.07_VMC_Img_No_7.png

NASA later chose not to use our pass, so we decided to use it to perform a VMC observation instead.

The images we took were then stitched together to form a short video where Gale Crater can be seen as the dark horseshoe shape midway up the left hand side of the screen. This offset is due to VMC being set at 19 degrees from MELACOM.

We are, once again, back: Mars Express VMC resumes raw data posting

With not too much fanfare, December saw the Mars Express mission operations team at ESOC bringing the VMC back online, again. You'll recall that VMC went offline in late 2011 when Mars Express suffered problems with the mass memory storage. The spacecraft and instruments were fully back in routine operation by January 2012, meaning that the team could then devote some 'time-available' time to recommissioning VMC. In addition to getting the camera itself running (marked by the first symbolic data transmission of a VMC image via Malargüe station), we also set up a new blog channel and a dedicated Flickr page to host the images (and the Twitter account – @esamarswebcam – is still running).

Over at the Planetary Society blog, Emily Lakdawalla posted an update explaining the return of the VMC and including comments from Daniel Lakey, one of our MEX engineers looking after VMC. There's little improving on her excellent report, so with no further ado, please (a) take a look at her gorgeous collage '56 views of Mars from the Mars Webcam in 2012' reproduced below, and (b) head over to her blog and read her update in full.

Following the first downlink over Malargüe tonight, we will consider the Flickr page to be open for business. Unfortunately, due to the upcoming solar conjunction and associated low bit-rate season, we're unlikely to get any downlink slots for VMC for a few months, but once the Mars Webcam is taking pictures again, the images will be published for the world to see within seconds of them being received on Earth. The low priority of VMC images means that their downlink to Earth can be some time after the observation.

First data via Malargüe station: Mars as seen by VMC

Marking its inauguration, ESA’s Malargüe tracking station receives Mars Webcam image.

First data via Malargüe station: Mars as seen by VMC

An image of the enigmatic Red Planet acquired by ESA’s Mars Express on 15 December 2012 was downloaded via ESA’s new tracking station in Malargüe, Argentina, symbolising ‘first data’ and recognising formal inauguration.

Details on the station's inauguration via ESA web and ESA media.
