Цитата: undefinedPandemic delays big-ticket launches by Isro this yearIsro was to carry out the first unmanned flight of the human-rated GSLV Mk III and the country's first solar mission, Aditya L1, in December, according to the revised schedule.By Anonna Dutt, Hindustan Times, New Delhi PUBLISHED ON JUN 24, 2021 02:53 AM ISTThe Indian Space Research Organisation's (Isro) big-ticket launches planned towards the end of this year are likely to be delayed after the second wave of the Covid-19 pandemic impacted the timeline, people aware of the matter said on Wednesday.After the first wave of the pandemic last year, a committee of the space agency reviewed all pending missions to reschedule them. Isro was to carry out the first unmanned flight of the human-rated GSLV Mk III and the country's first solar mission, Aditya L1, in December, according to the revised schedule."The decision on the new timelines for the missions is awaited," an official from the agency said on condition of anonymity. Another official said the missions were likely to be delayed beyond their schedule.Last year, the space missions were impacted by the inability to move equipment and parts from across the country during the lockdown necessitated by the pandemic.The third lunar mission, carrying aboard only a lander and rover, was initially slated for the end of 2020 or beginning of 2021, but has since been pushed to 2022. The government green-lit the third mission soon after the lander-rover of the Chandrayaan 2 mission crashed and lost communication just 2.1km from the surface.The first unmanned Gaganyaan flight was initially planned for December 2020, the second for July 2021, and the first manned spaceflight was to happen by December 2021 ahead of the Prime Minister's deadline of Independence Day 2022.Only three PSLV missions have been carried out since the pandemic began last year - the EOS-1 earth observation satellite mission in November, the CMS-1 communication satellite mission in December, and a mission carrying the Brazilian earth observation satellite as the main payload in February.The launch of GISAT 1, an earth imaging satellite, was postponed in March last year after technical issues following which it was scheduled for March this year but is yet to happen.
ЦитатаISRO Postpones First Human Rated Test Flight for Gaganyaan Mission Due to COVID-19 LockdownBy IANS10 hours agoTWC IndiaThe first test flight of Geosynchronous Satellite Launch Vehicle-Mk III (GSLV Mk III) that is expected to carry the Indian astronauts to space will not happen this year owing to the COVID-19 pandemic and the lockdown."Owing to the spread of coronavirus infection and the lockdowns across the countries, vendors are working at a lower capacity or closed which in turn has impacted the supply of components. Even our officials are working from home due to the lockdown," K. Sivan, Chairman, Indian Space Research Organisation (ISRO) and Secretary, Department of Space told IANS.He also said most of the design and documentation activities have been completed for the rocket. Pointing out ISRO opening the year 2021 with the successful launch of Brazilian satellite Amazonia-1 and 18 other satellites, he said the spread of COVID-19 and lockdowns curtailed the operations.The first human-rated unmanned GSLV-Mk III, the first of the two test flights, was scheduled to fly by the end of 2021. Taking the flight results another unmanned rocket would fly while the third rocket will carry the Indian astronauts."Major design and documentation activities for the Ganganyaan project have been completed," Sivan added.An ISRO official had earlier told IANS that the crew module is under development and orders for 80 per cent of the hardware have been placed.According to the official, the static tests of the rocket's solid-fuel motor are slated this September and liquid fuel engines will also be tested. Meanwhile, the four Indian astronauts returned to India this March after completing their training in Russia and will undergo different space mission-specific training in the country.Sivan also said ISRO is waiting to launch India's first Geo Imaging Satellite (GISAT-1) to be placed in geostationary orbit.Queried about launching the satellite using foreign rockets like Ariane of Arianespace as there is an opportunity cost involved with a fully built satellite on the ground Sivan said: "Only China and the US are launching rockets. Others are not. Anyway, we have our own rocket to launch."He said once the COVID-19 spread comes down, the satellite will be launched.The satellite and the rocket (Geosynchronous Satellite Launch Vehicle - F10 (GSLV-F10) is ready at the rocket launch centre in Sriharikota. The GISAT-1 will be the country's first sky eye or earth observation satellite to be placed in geostationary orbit.Originally the GISAT-1 was slated for launch on March 5, 2020, but hours before the launch ISRO announced the postponement of the mission owing to some technical glitch.Soon after the COVID-19 pandemic and the lockdown delayed the mission. The rocket had to be dismantled and cleaned up.Subsequently, the GISAT-1 launch was slated for March 2021 but due to problems in the satellite's battery side, the flight got delayed and the battery was replaced.The Indian space agency had earlier said the 2,268 kg GISAT-1 would provide a real-time image of a large area of the region of interest at frequent intervals. It will also enable quick monitoring of natural disasters, episodic events and any short-term events.
