ISRO to perform key manoeuvre on Mars Orbiter next year

Quote
With the Mars Orbiter Mission completing two years, ISRO today said it will be doing a "major event" of effecting a manoeuvre on the Orbiter next year to reduce the impact of an " eclipse duration" to allow the spacecraft "survive" for more time.
Quote
"Our next major event in the Mars Orbiter will be sometime in the beginning of next year when we will be doing a manoeuvre to reduce the impact of the eclipse duration the satellite is going to encounter," he told reporters here.
He said during an eclipse the battery in the satellite has to support its operation and if the eclipse duration is "very long" then the battery may not be able to support it.
"So we intend to do a manoeuvre of the spacecraft so that the impact of eclipse duration will reduce and with that we will be able to survive for many more years because the satellite still has large (amount of) fuel left in it," he added.

Danielson and Kalocsa - Craters on the planet Mars

Danielson crater is named after scientist George E Danielson who developed many space cameras flown to Mars. This crater is of 60 km width and is filled with layered sediments. Kalocsa crater lies below the Danielson crater and is of 33 km width. However, Mars Kalocsa crater does not show any layered sediments as seen in Danielson crater, though collocated with Danielson crater.

Mars Colour Camera (MCC) image was taken on September 24, 2016 at an altitude of 2453 km with a resolution of 122 meters.

I wish they write the names of these craters beside them, not over them.

Global images of Mars: http://www.planetary.org/blogs/emily-lakdawalla/2016/20161006-fun-with-mom-mcc.html
Beautiful ! Emily's efforts in this deserves to be lauded. I too feel that the greatest impact that MOM would have in popularising Mars exploration would be through these beautiful global snaps, even if it has limited scientific value. Her feedbacks are valuable, and needs to be conveyed back to the MOM team and the ISRO leadership. I'm wondering how..

Quote
NASA’s Jet Propulsion Laboratory is forecasting the arrival of a global dust storm on Mars within weeks. The storm is expected to envelop the red planet, and reduce the amount of solar energy available to NASA’s rovers, Opportunity and Curiosity. The storm will also make it harder for orbiters to do their work.

May not be the right thing to say considering the adverse effects the dust storm will have on Mars landers and rovers on the ground, but I feel this might be a good opportunity for MOM to put its camera into action, and capture how the storm spreads across the planet. Might help a little  in understanding these storms too.

Masursky and Sagan - Craters on the planet Mars

The Masursky is a crater in the Oxia Palus Quadrangle of Mars. Another crater seen in the image is Sagan named after Carl Sagan, the famous astronomer.

This image was  Captured on Sept. 16, 2016 from an altitude of 3319 km with a resolution of 166 m.

Nothing much about space science really, but together with the atom bomb news  here in India that Govt has demonetised existing INR 1000 and INR 500 currency notes, the planned new INR 2000 note is supposed to depict Mangalyaan aka MOM.

PS: Apologies for the poor quality of image. Couldn't find a better one.

Juventae Fons and Baetis Chasma - Terrains on planet Mars

This MCC picture was taken on Oct. 16, 2016 from an altitude of 1015 km with a resolution of 51 m. This RGB image has been color corrected and enhanced for better visual appeal.

This spectacular terrain at the bottom of the image  is known as  Juventae Fons.   Another terrain seen at the top left corner is known as Baetis Chasma.

ISRO folks themselves admitted that this was kind of a rushed up mission and nothing more than a tech demo. They designed and developed most, if not all, instruments in-house and had very little input from the wider academic community. Even prior to the launch they had declared that the mission would be considered a success if it makes to the Mars orbit, and any subsequent data would be considered a bonus. By contrast, ISRO describes the upcoming MOM-2 as a pure science mission and is actively seeking proposals from the academics for its instruments.

As the article itself says the instruments of MOM were designed by engineers, not scientists. So, I guess we can very well forgive ISRO for this slip.

Isro realigns orbit of Mars mission spacecraft Mangalyaan

Quote
AHMEDABAD: Indian Space Research Organisation has successfully realigned the orbit of its Mars Orbiter Mission 'Mangalyaan' so it is not affected by long-duration eclipse, Isro chairman A S Kiran Kumar said on Thursday.

"The duration of the eclipse was so long that had we done nothing, the Mangalyaan's battery capacity would have got exhausted due to lack of sun rays. No effect of the eclipse was felt on Mangalyaan on Wednesday.

Quote
"The experiment was successful. The spacecraft still has 30kg fuel left, and with realignment we expect it to work for a very long time to come," he said.

The correction in the trajectory of Mangalyaan was required to keep the power supply strong during the eclipse - caused by shadow of Mars falling on it for 7-8 hours - so that it could continue to function longer, as Mangalyaan's battery cannot support long-duration eclipse.

why is this topic still in the Live Event section?!?
it should belong to Space Science Coverage or Indian Launchers, right?
