[kurup]

Salient points from interview of outgoing VSSC Director M.C.Dathan ..... from Mathrubhumi daily dated 30 May 2015 .

* PSLV-28 launch on July 10 in a commercial mission carrying 3 foreign satellites .

* RLV-TD launch on July or first week of August . The TD will be recovered after splashdown .

* PSLV C-30 with Astrosat will be after that .

* GSLV D-6 (MK2 variant) with fully completed indigenous cryogenic engine CE-7.5 will be launched in August .

* 2 more IRNSS satellites will be launched by year end .

* GSLV MK3 aka LVM3 fully configured version first flight will takle place in 2016 beginning .

* Chandrayan-2 with home-built orbiter , lander and rover will be launched in 2017 .

* Human Space Mission will be carried out in 5 years . (I think he meant within 5 years once the govt gives nod)

What is India's most powerful rocket and how does it match up to the most powerful Chinese rockets.

What is India's most powerful rocket and how does it match up to the most powerful Chinese rockets.

Indian most powerful rocket to date is the GSLV mk3 and can carry upto 10 tons to LEO. China outdated rocket LM3B can carry upto 13 tons to LEO. The new upcoming Chinese rocket LM5 will carry upto 25 tons to LEO. So China like always is leading.

These are all successful ones bro.

One of the reason being Indian rockets carrying low weight is Fuel they use. CHina has moved to NEPE while india used 10% less efficient fuel.

The other reason is that Our geostationary vehicle are a bit away from achieving their full potential. We have yet to use semi cryogenic engine in second stage. This will boost Geo load by further 2 tons. Composite Moter may further boost the load carying.

Mars orbiter readies for June outage - The Hindu
Mars Orbiter Mission, the Indian spacecraft going around the red planet, has been functioning in a basic, silent mode for the past few days preparatory to an impending two-week-long signal blackout.

MOM faces a communication outage during June 8-25, when Sun will be in the background of Mars with respect to Earth and disrupt communication. Mars will be flanked by Earth on the other side.

For almost a month from May 27, its payloads will remain shut down and only stored telemetry signals or a health report will be sent for three hours a day, ISRO Satellite Centre Director M.Annadurai told The Hindu. Information on the remaining 21 hours was being stored and sent in those three hours.

Think of Sun being behind an object that you are photographing, he explained. The satellite is `silent’ and it has been programmed to operate the basic maintenance on its own for about a month, he said, adding DTH operations on ground periodically face such situations. ISRO Satellite Centre Director M.Annadurai told The Hindu. Its five instruments will not work during this period.

MOM, launched in November 2013, has been orbiting Mars since September 2014, making India the first country to reach Mars in the first attempt. It has outlived its planned time of six months. Dr. Annadurai said it could go on for some more time at the current rate as "Fuel on the spacecraft is not an issue."

The images, chemical and topographical data that it has sent are being collated by scientific teams. A primary search is for any hint of methane from its surface - which can indicate ancient life on Earth's neighbour.

It goes round Mars in an ellipse almost once in three Earth days, closest to Mars at about 450 km and farthest at 72,000 km.

Heavy Lift Launch Vehicle concepts

ISRO have carried out study of 4 different concepts of HLV to date . These are explained below in random order .


Concept-1

Payload Capacity : 25 tons to LEO (10 tons to GTO)

A Heavy lift Launch Vehicle capable of placing up to 10 ton class of spacecrafts into Geosynchronous Transfer Orbit is currently under study by a project team. This new generation launch vehicle will derive its propulsion modules from LVM3 as well as from new developments, which include :

1) semi cryogenic booster stage, SC200
2) larger solid strap on boosters as compared to S200 strap on motors used in LVM3 (S250) and
3) a larger cryogenic upper stage (C50).

Welcome to VIKRAM SARABHAI SPACE CENTRE - Heavy Lift Launcher


Concept-2&3

Concept 2&3 together was supposed to carry out a human mission to moon . It was first shown in a presentation by ISRO at the IAC 2009 .

Concept-2 = Crew Launch Vehicle
* Architecture - 4 S230 + SC500 + C60
* Liftoff weight - 1690 tons
* Capability - 31 tons to Low Earth Orbit
* Payload - Crew Module (6 tons) + Service Module (25 tons)

Concept-3 = Carge Launch Vehicle
* Architecture - 8 S230 + SC800 + C60
* Liftoff weight - 3075 tons
* Capability - 84 tons to Low Earth Orbit
* Payload - Earth Departure Stage (67 tons) + Lunar Descent Module (17 tons)

Concept-4

Single LV capable of Lunar Man Mission with payload capacity of 100tons to LEO

This looks like a single LV capable of replacing two LV of concept-2&3
