ISRO had earlier said Chandrayaan-2 will be launched in a window from January-February 16, 2019.
India has planned 32 missions, including the "most complex" Chandrayaan-2 during 2019, the Indian Space Research Organisation has said.
India's maiden human spaceflight programme 'Gaganyaan' activities would go full steam to accomplish the various development and qualification milestones during the year, the space agency said.
"The year 2019 promises to be much more challenging to the ISRO community with 32 planned missions (14 launch vehicles, 17 satellites and 1 Tech demo missions)," ISRO Chairman K Sivan said in a New Year message.
"This includes the most complex Chandrayaan-2, which will be the 25th mission from SLP (second launch pad), and the development flights of Small Satellite Launch Vehicle (SSLV)," he said.
ISRO had earlier said Chandrayaan-2 will be launched in a window from January-February 16, 2019. Sources said it is expected by the middle of next month but no date has been finalised.
"We are all trying hard. Definitely, it should be possible to launch the mission in February," a senior ISRO official said. "There is no impediment. It's on track," the official said.
Chandrayaan-2 mission, costing nearly Rs 800 crore, is an advanced version of the previous Chandrayaan-1 mission about 10 years ago. This spacecraft to be launched on board GSLV-Mk III is a totally indigenous mission, comprising an Orbiter, Lander and Rover.
Sivan said during the year, Gaganyaan activities would go "full steam" to accomplish the various development and qualification milestones. The Union Cabinet gave its nod for the Rs 9,023-crore programme last Friday.
The objective of the mission is to carry a three-member crew to low earth orbit and return them safely to a predefined destination on Earth. Prime Minister Narendra Modi had on Independence Day announced that the mission would be undertaken by 2022.
ISRO is aiming to reinstate its microwave remote-sensing capability through the RISAT (Radar Imaging Satellite) series and attain operational Geo-imaging capability through the GISAT (GEO Imaging Satellite) series, according to Sivan.
It is also planned to progressively improve the payload capability of GSLV (Geosynchronous Satellite Launch Vehicle) and its variants. The country would meet the high throughput bandwidth requirement of Digital India and also in-flight connectivity with the launch of GSAT-20.
On the application side, crop production estimation would be enhanced to cover 10 additional crops and also provide vital inputs for water and energy security, Sivan said.
He said 2019 is the birth centenary of the founding father of Indian Space Programme, Vikram A Sarabhai, and year-long celebrations, consisting of a host of national and international events, would commence August 12, 2019.
Terming 2018 as a year of many 'firsts' and 'beginnings' with profound growth in all directions, he said during the year ISRO completed 16 missions, signing off with seven successful missions within 35 days.
This included two successful GSLV missions in a single year.
Among other things, the period also witnessed active discussions and partnerships with other space agencies in advanced technology areas of human spaceflight and other areas like LOX/Methane propulsion, joint satellite missions, among others, he said.
