India's Tata Advanced Systems Limited (TASL) has launched an Earth observation satellite that can be leveraged by the Indian Armed Forces to enhance surveillance of strategic areas of interest.

The satellite, named TSAT-1A, was carried into space by SpaceX's Falcon 9 rocket as part of the Bandwagon-1 rideshare mission, which was launched from the Kennedy Space Center in Florida on 7 April, a spokesperson for TASL confirmed to Janes on 8 April.

TASL built TSAT-1A in collaboration with North Carolina-based Satellogic, following a collaboration agreement between the two companies in late November 2023.

TSAT-1A is an optical sub-metre-resolution Earth observation satellite. “TSAT-1A will deliver high-resolution optical satellite images with increased collection capacity, dynamic range, and low-latency delivery through its multispectral and hyperspectral capabilities,” TASL said.

A spokesperson for TASL previously told Janes that TSAT-1A can “enable defence forces to enhance their preparedness, response capabilities, and strategic decision making”.

TASL added that TSAT-1A was assembled at an assembly, integration, and testing (AIT) plant in its Vemagal facility in the southern Indian state of Karnataka.

TSAT-1A is based on Satellogic's NewSat Mark V satellite, which includes a four-band, 70 cm multispectral camera with monochromatic full-motion video capabilities, and a 29-band, 18 m hyperspectral camera. According to Satellogic, the NewSat Mark V has a lifespan of three to four years.

@Gessler later I will be going through this, within it ISRO's Director for Liquid Propulsion says that the upcoming 'Soorya' rocket will have 32 tons to low earth orbit, ~3x of the capability of LVM3

He also said that in "1 or 2 months," they will be attempting a 200s flight of the HAVA:

The Indian Space Research Organisation (ISRO) has successfully completed the first ignition test on the Semi Cryogenic Pre-Burner Ignition Test Article.
ISRO is developing a 2,000 kN thrust semi-cryogenic engine working on a LOX Kerosene propellant combination to enhance the payload capability of LVM3 and for future launch vehicles.

Lead centre​

The Liquid Propulsion Systems Centre is the lead centre for the development of semi-cryogenic propulsion systems, supported by ISRO’s other launch vehicle centres.
The propulsion modules were assembled and tested at the ISRO propulsion complex (IPRC), Mahendragiri. As part of the engine development, a pre-burner ignition test article, which is a full complement of the engine power head system excluding the turbopumps, was realized.

First ignition trial​

“The first ignition trial was conducted successfully on May 2, 2024, at semi cryo integrated engine test facility (SIET) at IPRC, Mahendragiri, which was dedicated to the nation recently by the honourable Prime Minister of India. Smooth and sustained ignition of the preburner is demonstrated which is vital for the starting of the semi-cryogenic engine,” ISRO said.
The space agency added that the successful ignition of a semi-cryo preburner is a major accomplishment of ISRO in the development of semi-cryogenic propulsion systems.

Excellent, they were having some problems with this last year....looks like its been resolved now and more development on this program can proceed.
