    There is a launch window for Mars in 2016 but this cannot be met. We would definitely go with the 2018 launch window
    to potentially loft a lander+rover payload to Mars using the new GSLV Mk-2 or Mk-3 rockets that should be ready & available by then.

    The concepts would also be partly validated in the Cdy-2 mission to Moon (carrying an orbiter+lander+rover) which should be done
    before that.

    Mars Orbiter Mission begins collecting science data

    Srinivas Laxman, TNN | Nov 6, 2014, 07.26AM IST

    MUMBAI: The Mars Orbiter Mission (MOM) has kicked off its science phase and its five payloads are gathering data in full swing, said director of Isro's Space Application Centre, Kiran Kumar.

    The MOM entered the Martian orbit on September 24 and made history by achieving success on its maiden flight. Google celebrated the first month the orbiter's entry to Mars with a doodle on October 24.

    Speaking to TOI on Wednesday, which marked the first anniversary of the MOM launch on November 5, 2013, Kumar said the data downloaded from the spacecraft at the Indian Deep Space Network in Byalalu, off the BangaloreMysore highway, is being transmitted to the principal investigators for analysis.

    Kurian Mathew, principal investigator of the Methane Sensor For Mars, said: "We are analyzing data from both from Mars and comet Siding Spring. We will highlight them at an appropriate moment."

    The Methane Sensor For Mars has been described as the "bridegroom" of all the payloads as its findings are expected to have huge ramifications. Indian Space Science Data Centre's general manager J D Rao could not hide his excitement. "We are anxiously waiting for the results," he told TOI on Wednesday.

    The quality of the pictures taken by the Mars Colour Camera in the last one-and-half month has attracted considerable praise from across the world. However, for some unexplained reason the first anniversary of MOM's launch on Wednesday remained a quite affair with no mention of it in Isro's Facebook and Twitter accounts.

    MAn if that Oort cloud tanker landed on Mars there would have been a lake of ice to ski on ;)

    Mars Orbiter Mission will live on, beating anticipated life expectancy

    BENGALURU: India's first interplanetary mission has achieved another feat. The Mars Orbiter Mission (MOM), which will complete its designated life around the Red Planet on March 24, will have an extended life, thanks to its minimal fuel consumption.

    The Indian Space Research Organisation (Isro) is likely to make an announcement regarding extended life in the coming days. However, how much longer MOM will live will be known only after a solar eclipse in April-May.

    MOM sends freshs pictures, methane sensors are working fine
    Published March 4, 2015
    SOURCE : TNN

    [​IMG]

    The Mars Colour Camera (MCC) aboard India’s Mars Orbiter Mission (MOM) has sent in new images of the Red Planet, showing a volcano, and a canyon on the surface and one of Mars’ natural satellite Phobos.

    The new set of images were released late Tuesday by Isro, which has also said that the methane senors on the spacecraft have begun studying the albedo of the Red Planet — fraction of solar energy (shortwave radiation) reflected from Mars back into space. It is a measure of the reflectivity of the surface and will help study methane.

    The study of methane is a crucial objective of the Rs 450-crore mission, as methane is an indicator of life on the red planet. While the findings from the methane sensor released by Isro is completely technical, a senior scientist said the team is working on simplifying the same and releasing it for better comprehension by Wednesday evening.

    MOM is alive because it’s ‘screwed up’

    [​IMG]

    BENGALURU: A year since the launch, and over three months in the Martian orbit, if MOM continues to be operative, it's because thousands of titanium screws hold it up. "About 2,000 screws are holding the Mars Orbiter Mission in space," S B Salimath, a technician in the mechanical stream with Isro told TOI.

    These screws, made of titanium that has low density but high strength, have gone into all the packages that the 1,350-kg spacecraft has. The MOM was completed in a record 15 months to fly out of Earth on November 5, 2013.

    "Packages are nothing but a host of printer circuit boards and other components that make the spacecraft," said K M Lakshminarayana, a technician in the electrical division. Between him and Salimath, they have 58 years of experience and lakhs of screws.

    There are 30-40 major packages like the telemetry package, the telecommunications package and power package, each of which is made of smaller packages. Eventually, the spacecraft becomes one large package with additions like the solar panel, sensors and thermal equipment.

    "We are the ones who execute the design and plan of scientists and engineers. Thermal equipment, for example, is extremely crucial for deep space missions and our division puts it in place," said Udayshankar Kalmat, another technician working with Isro for 32 years.

    While the faces of the space agency are the ones that face the wrath or hog the limelight, tens of people like Salimath work to realise the nation's dreams. In Bengaluru alone, 23-29 teams — all from the Isro Satellite Centre (ISAC) and Laboratory for Electro-Optics Systems (LEOS) — have worked on MOM. Each team is headed by a project manager, who reports to a deputy project director who, in turn, is answerable to the project director. "The composition of the team varies but an average of 7-10 members make one team, and sometimes the numbers are more," another Isro official said.

    Explaining the kind of screws used, Salimath said, a majority of them are allen screws which have hexagonal sockets. "We also use countersinking screws, cheesehead screws," he said.

    Kalmat said that the dimensions of the screw do not go beyond M-10, and the smallest one used is M3.

    Images of Eos Chaos region of Mars taken by Mars color camera on board ISRO's Mars Orbiter Mission on 5-2-2015 at a spatial resolution of 220 m from an altitude of 4403 km. Eos Chaos is located at eastern part of Valles Marineris region. Grabens/Fracture patterns at the edges of Valles Marineris are clearly seen at this resolution. Images at this coarse resolution are useful for understanding geological processes at regional scale.

    This spectacular image reveals Phobos, one of the two moons orbiting Mars (the other is Deimos), silhouetted against the Martian surface (shown). Although Phobos is the larger of the two moons, it is still only about 14 miles (22km) across, and completes an orbit of Mars once every seven Earth hours. The odd colour of Mars is due to the specific filters used by the camera

    Methane Sensor for Mars (MSM) payload onboard MOM intends to detect the presence of Methane and measure the column density of the same. One of the secondary objectives of this payload is to measure the reflectance of Martian surface in 1.65 micron. MSM has two channels, Methane and reference to measure the radiance from the surface of Mars.
    All planets in the Solar system receive Sun’s radiation to varying degrees depending on their distance from the Sun. Observing the surface of the planet depends on how this radiation is reflected back. Reflected solar radiation from Mars is a diagnostic signal of the planet which provides lot of information about the planet’s surface as well as its atmosphere. When we measure the radiance in a specific wavelength of light (in this case, 1.65 micron), then we can generate a reflectance map.
    The map presented here shows the surface reflectance of Mars as viewed at 1.65 micron from the reference channel of MSM till December 16, 2014. In the map, the blue colour indicates low albedo features and the red shows high albedo features on the Martian surface.
    The map resolution is 0.5°x0.5° in Latitude-Longitude. By correcting the data for CO2 absorption, a major part of atmospheric effects is taken care of. This data along with the reflectance measured by Mars Colour Camera will be useful to study the surface properties of Mars.
