The Indian Space Research Organisation (ISRO) crossed an important milestone with the successful launch of weather satellite INSAT-3DR using a Geosynchronous Satellite Launch Vehicle equipped with the indigenous cryogenic upper stage. ___________________________________. That September 8 launch marks the third consecutive success; the fact that it is the first operational flight by the GSLV carrying the indigenous cryogenic upper stage is confirmation that India now belongs to the elite club of countries that have mastered the cryogenic technology.
ISRO is a research and development organisation and not a production organisation, but the lack of greater industry participation has resulted in it being unable to launch more satellites in a year using the GSLV.
Incorrect AnswerUnlike in the case of the PSLV where industry participation is around 80 per cent, it is only about half in the case of the GSLV.
Incorrect AnswerThe successful launch marks a departure from the long history of failures with the GSLV; except for the first, every launch of the Polar Satellite Launch Vehicle (PSLV), the workhorse of ISRO, has been a success.
Correct AnswerThe first experimental flight using the GSLV-Mk III is scheduled to take place by the end of this year and will use a new cryogenic engine.
Incorrect AnswerWith an ability to provide double the thrust compared with the current cryogenic technology, the vehicle would be able to carry payloads up to four tonnes.
Incorrect AnswerExplanation:
Correct Answer is (c).In we read the paragraph carefully, we can observe that the first three sentences - the one preceding the blank, the one for the blank, and the one following the blank speak of three consecutive success with respect to ISRO.
Among the given choices, Option C is the best fit for the blank as it takes the discussion further and points to the second success in a row.
Option C is hence the correct answer.
