The trajectory can be flown any month but the combination of trajectory and illumination is more restrictive and repeats at 6 month intervals.
India’s second mission to the moon, Chandrayaan-2, is likely to be launched only in October. Further delays cannot be ruled out if systems are not yet in place by then.
An Isro official told TOIseveral tests have to be done and arrangements need to be made.
The original plan envisaged the launch between April and November with the real target focussed for April. Top Isro officials had expressed confidence that the takeoff will happen in April.
But on Friday, it was stated the lunar mission was not yet ready for an April lift-off and much still needs to be done.

The launch of India's second lunar mission 'Chandrayaan-2', slated for next month, has been postponed to October as the experts have suggested some tests, the ISRO said today.
Dr Sivan said, “The original targeted date for the launch was kept on April 23. However, as the ongoing tests for the lunar mission will take 20 more days, the April 23rd date could not be met. Therefore the panel decided to defer the launch. Unlike, other satellite launches where Isro could easily defer the launch by a day or two to get a perfect mission, Isro can’t do the same in this mission. This is because the ideal date for the moon launch comes only once in a month. If we skip that date of the month, we have to plan the launch next month. After April, if Isro launches the mission from May to September, we won’t be able to utilise the full lunar day (14 Earth days) for experiments on the moon because of eclipses. Therefore, Isro will launch the mission in the first week of October.”
“All these new things are being done keeping lunar mission in the mind and ISRO’s bigger game plan to increase GSLV payload capability. For Chandrayaan-2, we are formulating a perfect combination. The four strap-ons and second stage will be boosted with high-thrust Vikas engines; cryogenic upper stage will be loaded with enhanced propellants of 15 tonnes instead of current 12.8 tonnes and will be operated with 9.5 tonne thrust compared to the present 7.5.”
^ That can't be right, at least it shouldn't be! ISRO has repeatedly stated that October would be an ideal month to launch Chandrayaan-2, because of the earth-moon distance at the time. Must be a major oversight by NDTV-one is hoping anyway!
[According to this this Economic Times report also, the launch of Chandrayaan - 2 is not on cards this year. This makes me believe that Chandrayaan - 2 will NOT be launched until the launch of GSAT-7A by GSLV-II. I think, ISRO does NOT want to take risk without testing the capability of high thrust Vikas engine.
Dr M Annadurai, Director of U R Rao Satellite Centre confirmed to NDTV that the launch date for Chandryaan-2 "is slipping to 2019" from the initially planned launch in October this year. Dr Annadurai said that India's moon mission now aims to land in February and the rocket launch will take place in January next year.Moreover, since the weight of the Chandrayaan-2 satellite has increased, Dr Annadurai said that now instead of GSLV MK-II, GSLV MK-III will be used

For something as complex as a moon mission, better not to take chances. But the news of GSLV Mark 3 being used for the launch, is startling. That was never spoken of before by ISRO, now it's pretty concrete! All this time, only GSLV Mark 2 was spoken of.

Dont want to indulge in a political debate but i find news articles of Mr Bagla to be quite irritating in nature as it's more on nationalism and jingoism rather than on science....3rd country to do this,4th country to do that,gslv the bahubali rocket etc etc....
^Agree. There's a little too much of that nationalism and jingoism in Bagla's reports- and he's supposed to be a science writer! It's okay to mention it, but it shouldn't be the centrepiece or the dominant theme. I don't like Frontline magazine( way too left politically!) but they have excellent science and technology articles by T.S Subramanian and R. Ramachandran, particularly in the area of aerospace. The first, second, 5th, 6th et al are certainly brought up, as they should be, but the accent is on the actual science and technology, and the challenges therein.
