follow-up mission mission to Chandrayaan-2. Called Chandrayaan-2A, the mission would demonstrate a soft landing using a lunar lander with optional ascent capabilities that would allow the spacecraft to "hop" on the moon.

The propulsion module will basically be a space tug, with LAM, propellant tanks. For those who still remember the planned PAM (Payload Assist Module) for Mk2, this will be something very similar (and very straightforward to realize). I suspect the stack can only be launched on a Mk III.
There was also the possibility of an alternate profile where the lander (with rover) could have been launched on a direct trajectory to the moon by a Mk III (no need for orbit raising). In this case the engines on the lander would be responsible for making the LOI burn. But would have required a redesign of the lander to carry more propellant .
They are likely to be trained by Novespace, a CNES subsidiary, on parabolic flights aboard the Air Zero Gravity, which is a modified version of an Airbus A310, a CNES official said. This will provide the astronauts a zero-gravity environment on Earth.

The CNES will also provide India equipment for life support that astronauts will wear during Gaganyaan, scheduled for 2022. They will be using several French devices for health monitoring — eyewear device featuring a bluetooth connected garment which is equipped with biomedical sensors, aquapad cotton for quick and easy testing of water, specific equipment for waste management, or even food packaging.
They may even use other devices such as the ECHO, an ultrasound system tele-operated by doctors on the ground, or the Cardiomed to measure cardiovascular activity. CNES expert Dr Brigitte Godard has already spent time during July and August in Bengaluru to train physicians and personnel, said the official.
The Indian physicians and engineers involved in Gaganyaan will also be trained in France in the coming months. Training sessions will be for two weeks each, with teams coming and going. The training will be given at MEDES space medicine and physiology institute in Toulouse and by the teams at ESA’s astronaut training centre in Cologne.

The Indian Space Research Organisation is readying low-cost satellite launch vehicles costing about Rs 30-35 crore each, which can put into orbit
satellites weighing 500 kg.
The first such launch from the country is expected to take place in the next four months.
This capability will give ISRO a big commercial boost as it will be able to cater to micro, mini and medium segments of the market, Haridas T V, Deputy Director, Vikram Sarabhai Space Centre said, taking part in the panel discussions at 'EDGE 2020, The Space Conclave', here on Friday. "The biggest advantage is that ISRO now can manufacture these vehicles in a turnaround time of just three weeks," he said.
ISRO has earmarked $1,600 million for launch vehicles, of which $870 million will be for PSLV and the remaining for Geosynchronous Satellite Launch Vehicle, he revealed. ISRO has planned some 500 Polar Satellite Launch Vehicle launches in the next five years, a press release quoting Haridas said.
BENGALURU: The four Indian astronaut-elects, who left for Russia on Friday, have begun their 12-month long training on Monday.
The four Indian Air Force (IAF) test pilots, picked after thorough screening, have been put on the planned training programme at the Gagarin Research & Test Cosmonaut Training Center (GCTC) in Russia.
"GCTC has started the planned training programme of Indian candidates for a spaceflight under the contract between Glavkosmos, JSC (part of the State Space Corporation Roscosmos) and the Human Spaceflight Centre of the Indian Space Research Organisation (ISRO)," Glavkosmos said on Monday.
The 12-month training will include comprehensive and biomedical training, which will be combined with regular physical practices.
"In addition, they will study in detail the systems of the Soyuz manned spaceship, as well as they will be trained in short-term weightlessness mode aboard the special Il-76MDK aircraft," Glavkosmos added.
The Indian pilots will also be trained to act correctly in case of abnormal landing of the manned spaceship descent module in various climate and geographic zones. The most part of the training will take place at the GCTC facilities.
Isro chairman K Sivan had said on January 1 that the final four astronaut-elects had been selected.
And, as TOI had reported before that, India had picked 12 IAF test pilots who cleared the level-1 screening for the Gaganyaan programme which envisages to send Indian astronauts to space by 2022 in September 2019.
The Institute of Aerospace Medicine (IAM) under IAF, had selected the 12 astronauts from 60 applicants.
Apart from major details about the IRNSS and Navic. See if you agree, hope I'm wrong!

haridas ji is it too much to ask for what does that mean..the large no. indicates, which is out of pattern from previous nos, makes me think that we are going for something big in coming years..2022 or 2023 vintage...otherwise why would not we want to continue our 'nehindru' growth rate of few every year...

The ADMIRE based projects are welcome. But I have been hearing about them and seeing schematics for the past 2 years.
ISRO and NASA are together building a microwave remote sensing satellite with dual frequency (L and S band) Synthetic Aperture Radar," he said.
"Nasa will contribute L-band Radar, while Isro will contribute S-band Radar and the satellite. This joint mission is planned to be realised for launch in 2022. This is the world's first dual frequency SAR satellite," he said.

Whoa, am I misunderstanding/reading when it says "this flight" will use a semi-cryo( SC) engine? The flight that is upcoming any day or week now. That( the SC) wasn't supposed to be ready for another two-three years, to be actually flown. Wish the language was more precise!
Future RLV-TD flights will seek to validate landing and propulsion-related technologies in order to serve as a test-bed for a follow-on programme that aims to develop a much larger RLV. This RLV will feature a SC 500 semi-cryogenic engine as well as a cryogenic CE 50 engine giving it a semi-cryo fly-back booster and a cryogenic orbiter.
