The PMO intervened because pressure came from Washington.

What quotable evidence do you have to suggest this?

“The satellite has some voltage fluctuation issue which is delaying the launch," one scientist in the know told TOI.

Not very clear whether the launch is going to be delayed past April 18th. Possible.

"We are working on the problem and the launch should happen in the last week of this month [April], or may even get pushed to May," a scientist said.

it seems that only ISRO is affected by COVID-19...all other space agencies/ companies are actually going faster than usual

its really frustrating

Given recent covid outbreak and possible countrywide lockdown this launch is likely to be pushed back at least a month if not several

India's Geo Imaging Satellite GISAT-1 launch further delayed
India TV News Desk | May 12, 2021 12:28 IST

Quote

/.../
Further, with the demand for oxygen shooting up from the hospitals to save Covid-19 patients, the Indian space agency's rocket may not be getting oxygen to power itself for some time to come thereby delaying its space missions.

The ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu is supplying oxygen to hospitals to save Covid-19 patients.

The satellite and the rocket (Geosynchronous Satellite Launch Vehicle - F10 (GSLV-F10) are ready at the rocket launch centre in Sriharikota.
