There's the usual Uncl'ish hyperbole/backstory stuff, but the capabilities are truly amazing! The fact that in 2020, they detected & classified 1000 missile launches across the world.

Made in Telangana rocket to launch by 2021-end
Hyderabad: Hyderabad-based space startup Skyroot Aerospace is gearing up to launch its first rocket later this year to put commercial satellites into space. The launch vehicle ‘Vikram-I’ which is under manufacturing and targeted for launch in December, hosts an Orbit Adjustment Module (OAM) that gives the final burn and inserts multiple satellites into space.

Skyroot, which builds small satellite launch vehicles (SSLVs), is among the nine ground-breaking startups and the only space startup in the country chosen to interact with the Prime Minister Narendra Modi to commemorate five years of Startup India initiative.

Pawan Kumar Chandana, co-founder & CEO, Skyroot Aerospace told Telangana Today, “This year, we have three full rocket stage tests. They will be done at Indian Space Research Organisation (ISRO) facilities one every 2-3 months before we go for a launch by end of the year.”

“We are building advanced rockets which can be assembled and used to launch satellites to space. We are the first to build a liquid, solid fuel and 100 per cent 3D printed cryogenic rocket engine. It typically takes two years to build a cryogenic engine, but we made this in two days using 3D printing and advanced materials such as super alloys,” he added.

The company won the National Startup Awards 2020 in the space category in October for its innovations. It is founded by former ISRO scientists, Pawan Kumar Chandana and Naga Bharath Daka.

Skyroot has created about 100 direct and indirect jobs so far and may create thousands of jobs in future, added Skyroot co-founder and COO Naga Bharath Daka.

Engine testing

Skyroot recently test-fired a solid propulsion rocket engine named Kalam-5, the first of its five Kalam-series rocket engines. The engine uses a carbon composite case and a more advanced version will be built and tested at ISRO’s facilities before powering Vikram-I by December 2021.
The company also has developed a fully cryogenic rocket propellant engine ‘Dhawan-1’, which is India’s first privately developed indigenous rocket engine which runs on liquefied natural gas (LNG) as fuel. “We are building a dedicated test facility for hot fire testing of this engine. We are aiming to test fire it in April,” Chandana added.

In another ‘India’s first’, the company test-fired its upper stage liquid engine named ‘Raman’, a bi-propellant engine. The engine hosts a 100 per cent 3D printed injector, which reduced its overall mass by 50 per cent and number of components and lead time by 80 per cent. It will be able to support long duration missions as an orbital platform for space experiments and SmallSat deep-space missions.

Some real science:

https://swarajyamag.com/insta/indias-dedicated-space-telescope-astrosat-spots-rare-hot-ultraviolet-bright-stars-in-milky-way-galaxy

The ultraviolet imaging telescope of the Astrosat, India's first dedicated multi-wavelength space satellite, has spotted rare hot ultraviolet-bright stars in the Milky Way galaxy, a Ministry of Science and Technology statement said on Thursday (21 January).

These stars whose inner core is almost exposed, making them very hot, exist in the late stages of the evolution of a Sun-like star. It is not clear how these stars end their lives as not many of them are detected in these fast-evolving phases, making their study crucial, the ministry said.

Looks like ISRO’s low cost model of micro satellite launches have got some serious competition. Space X next mission is planning to deploy 144 Satellites beating previous record set by ISRO

Where are those who called it space junk when ISRO did it?

Glad to see it posted here.. Science wise this is quite important and I am glad that Indian Newspapers are covering it.

A team from Indian Institute of Astrophysics captured five generations of UV Stars in a cluster using Ultraviolet Imaging Telescope onboard AstroSat, India’s first multi-wavelength space satellite. In September 2020, AstroSat completed five years in orbit with a UVIT fabricated also by IIA which has been doing an exceptional job of galactic spying!

Here is a ToI article.
