Sorry, couldn't find a thread on this program,So i am posting it on chandrayaan 2 topic

Moon Mission: Giant leap for startup

Quote
The Indian startup attempting to soft-land a craft on the Moon has just won funding from a host of bigwigs in the venture capital, technology and startup ecosystem, and accolades from some of India's leading space scientists.
The new investors in the venture include Subrata Mitra & Shekhar Kirani of Accel Partners (they have invested in their individual capacities), Sharad Sharma, former Yahoo India R&D head, Vivek Raghavan, chief product manager of UIDAI (the Aadhaar project), Pallaw Sharma, director of analytics at Microsoft based in Redmond, Bala Parthasarthy, serial entrepreneur and part of the AngelPrime angel investor group, Sunil Kalra, entrepreneur & investor, Paras Chopra and Pallav Nadhani, both founders of successful startups.

Quote
If Team Indus succeeds in its venture, it would be the first time India would be soft-landing a craft on the Moon. ISRO's Chandrayaan-1 orbited the Moon and then hard-landed, crashing itself on the Moon's surface. The Google Lunar XPrize, which carries $40 million in prize money, also requires that a rover will dismount from the landing craft and travel 500 metres on the lunar surface, and take high quality images. "The audacity of the plan was what attracted me to Team Indus. It's such a big and complex project," said Raghavan, who has been with the UIDAI project since its inception.

Quote
Going by the latest reviews of the project by top space scientists, Team Indus could well achieve its mission. V Adimurthy, a senior ISRO advisor and designer of the Mars orbiter mission, said about two years ago, when he first met Team Indus, there were many loose ends. "Three months ago there was another review, and what I saw made very good sense. It has become a very feasible project, and I think they can do it," he said.

K. Radhakrishnan, former chairman of the Indian Space Research Organisation (Isro), said on Saturday that work on Chandrayaan-II was in full progress and the nation can expect it to land an indigenously-built spacecraft with a rover on the surface of the Moon within three to five years.

Signs of Chandrayaan-II getting delayed to 2019-2020? The development of the lander should be pretty challenging, but any idea whether they are facing some major hiccups necessitating a delay? I remember reading a similar news report that quoted ISRO sources (maybe Radhakrishnan himself) saying the lander would be developed within 3 years and the launch can be expected within 5 years. Couldn't find it now.

Perhaps bumped in favor of the next Mars mission, rather?

ISRO generally works on one science mission at a time.  With four currently in development (AstroSat, Chandrayaan 2, Aditya, next Mars), if Chandrayaan 2 has indeed run into some development difficulties - say, mass growth(?) -  I would not be surprised by it being bumped.

Kiran Kumar: Medicine’s loss, Isro’s gain

Quote
"Isro is busy working on Chandrayan-2, which will be taken up in 2016-17," he said adding that Isro has been working for the people and will continue doing so.

Chandrayaan-2 might get launched sometime by 2017 after all, well, hopefully.

THRISSUR: Chandrayaan 2, India's second satellite mission to moon, will be launched in 2017, said M C Dathan, director of Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram.

Speaking after inaugurating the pavilion of the Indian Space Research Organisation (ISRO) at the Thrissur pooram exhibition the other day, Dathan said preparations are in full swing for the launch of Chandrayaan 2 at the various ISRO units including at the VSSC.

The launch will happen in the fifth sojourn of Geosynchronous Satellite Launch Vehicle (GSLV) Mark II rocket.

What is ISRO doing to mitigate any potential problems of the kind that the Chinese rover mission experienced?

Here's a youtube clip from a few years ago, which mentions the Laser Ablation Instrument as the primary investigative instrument onboard the Chandrayaan-2 rover:



The instrument will be used to zap rocks with a laser and analyze their surface composition via spectrometry. It will work on the same principles as the ChemCam on NASA's Mars Curiosity rover.

Quote
The ISRO’s Space Applications Centre (SAC) at Ahmedabad, which is designing the “eyes and ears” of Chandrayaan-2, has targeted to deliver all the payloads for the lunar mission by the end of 2015, official sources said. This includes three major payloads and a crucial set of sensors and communication equipment that will be fitted on to the orbiter, lander and the rover.

Quote
“The preliminary design review is over and the flight models are under fabrication. We will be delivering the payload by the end of this year or at the beginning of next year,” Misra added. SAC is developing three major payloads namely the Terrain Mapping Camera-2 (TMC-2), Imaging Infra-Red Spectrometer (IIRS) and L&S Band Synthetic Aperture Radar (L&S-band SAR). All these three payloads will be part of the orbiter that will encircle the moon.

Quote
The most challenging part of the Chandrayaan-2 mission will be the soft landing of the lander on the lunar surface. “SAC is developing all the sensors to provide the lander with real-time information for navigation need for a safe descent on the moon’s surface,” Misra remarked.
The sensors being developed are Orbiter High Resolution Camera (OHRC), Ka-band Altimeter, Lander Position Detection Camera (LPDC) and Lander Hazard Detection and Avoidance Cameras (LHDAC). While the OHRC onboard the orbiter will image the landing site and determine the exact descent point before the lander is ejected from the composite spacecraft, the other three sensors will guide the lander to the descent point.

Quote
SAC is also developing a HD video camera for both the lander and the rover. “The equipment on board the lander and the rover will have a mission life of just 14-15 days. The extreme temperatures on the moon will eventually destroy them,” Misra said adding that the equipment developed by SAC for the lander and the rover can withstand temperatures ranging between a freezing minus 30 degrees to a high of 70 degrees.

Quote
Apart from SAC, the Ahmedabad-based Physical Research Laboratory (PRL) will is also developing two payloads of Chandrayaan-2. This includes a X-Ray Solar monitor that will part of the orbiter and will observe the x-rays emitted from the Sun. PRL is also developing a rover payload called the Alpha Particle X-Ray Spectrometer that will determine the elemental composition (Mg, Al, Si, K, Ca, TiFe) of lunar soil and rocks around the lunar landing site.

For the landing of Chandrayaan-2 mission, a throttle engine is being developed, he said.

India already has a second visit to the Moon planned for 2018 through Chandrayaan-2 that will include an orbiter, lander and a rover on the lunar surface. This Rs 500 crore mission is already being put together in Bengaluru and it will be launched using the GSLV Mk-II.

According to ISRO it would `further our understanding of origin and evolution of the Moon with improved versions of Chandrayaan-1 instruments for imaging, mineralogy and chemistry; addition of alpha and neutron spectromet ..
Beyond Chandrayaan-2 ISRO seeks to plan for `lunar sample return missions from the polar region of moon and a possible establishment of lunar observatory'.

GSLV-MkII is not yet operationalized. After the second successive successful launch with indigenous cryogenic engine probably in August this year, GSLV-MkII will be declared operational. Then it has to be launched another 4 times to scale up its higher payload capacity that is critical for launching Chandrayaan-2 which is likely to have a launch mass of 2650 KG ( Lander and Rover Mass : 1,250 kg, Orbiter : 1,400 KG ). GSLV-MkII has so fare launched the highest payload of 1980 KG. Its payload capacity has to be increased further up to 2650 KG. According to wikipedia, the mission strategy has been revised to inject Chandrayaan-2 in a lower initial orbit (170 X 16980 km) with a higher lift-off mass of 3200 kg. so, GSLV-MkII needs to be launched more frequently to scale up its payload capacity. Can someone verify what would be the launch mass of Chandrayaan 2 ( 2650 KG or 3200 KG )  ??

Wait what, Chandrayaan II is going to be doing optical terrain relative navigation on landing as well ? ( Chang'e-3 appears to have been the first ) Whoa, i like how things are developing
