@isro’s latest rocket, #SSLV, is geared for launch with the space agency aiming for an early Feb launch carrying three payloads. While the main payload will be #EOS7, the mission is also expected to launch #Janus1 from US' Antaris & an Indian sat. 1/n
The Earth observation satellite #SSLV is scheduled to carry will be in the small satellite class with its mass not exceeding 200kg, while the other two satellites sharing the ride will be smaller. 2/n
#SSLV can launch around 500kg sat in a 500km planar orbit and its key features — low cost, low turn-around time, flexibility to launch multiple sats, launch-on-demand, minimal infra requirements, etc,. — can make it a go-to LV for commercial launches in the future. 3/n

#Thread #Update #SSLV

Here We Go: @isro, which couldn’t put put satellites into their desired orbit in its maiden launch attempt of #SSLV yesterday, is studying the various salvage options the rocket can employ to achieve a different result. 1/n
While an expert committee has begun its investigation into Sunday’s mission and would eventually make a set of recommendations, preliminary findings show that the velocity trimming module (VTM) — the terminal stage of the rocket — could not ignite. 2/n
After a smooth lift-off, 1st three stages performed nominally. Mission entered terminal stage where VTM was to ignite & place sats into desired orbit. For this, onboard comps needed info from accelerometers (sensors), based on which VTM's workload would be decided. 3/n

#Thread with details on today's #SSLV test & more:

Clearing the decks for the first flight of #SSLV, @isro today successfully carried out the ground testing of the newly developed solid booster stage (SS1) at SHAR. 1/n
The test happened at around 12.05pm. “This is the last test before the flight (developmental flight),” S Unnikrishnan Nair, director, Vikram Sarabhai Space Centre (VSSC), which is developing the SSLV, told me. 2/n
@isro will now schedule the first developmental flight which will put into orbit #EOS2 or #Microsat. While an official date for the developmental flight is yet to be arrived at, multiple scientists say it is expected to happen in the first half of this year. 3/n

#space #updates #breaking:

There are some key developments unravelling related to some important missions/projects by @isro in the coming weeks. I'll soon be putting out something on #Chandrayaan3 #RLVLEX (reusable launch vehicle landing experiment) & #SSLV.

#Thread 1/n
The Indian Space Research Organisation (@isro), which has already completed its first successful launch this year, is getting busy with a slew of key tests pertaining to three important missions/projects in the coming weeks, aside from a launch mission. 2/n
While the #PSLV mission is scheduled to launch EOS-6 or #Oceansat3 in the early part of April, important tests under the #SSLV and #RLV programmes have been lined up in the weeks preceding and following that. A #Chandrayaan3 landing test too is scheduled in March. 3/n
