What is Kalam-250?

Recently, Skyroot Aerospace, the leading space-tech company, has successfully test-fired the Kalam-250 at the propulsion testbed of the Indian Space Research Organisation (ISRO). 

About Kalam-250:

It is a stage-2 of Vikram-1 space launch vehicle. It is a high-strength carbon composite rocket motor, which uses solid fuel and a high-performance Ethylene-Propylene-Diene terpolymers (EPDM) thermal protection system (TPS).
The stage includes a carbon ablative flex nozzle along with high-precision electro-mechanical actuators for thrust vector control of the vehicle, aiding in achieving the desired trajectory. 
The second stage of Vikram-1 will play a crucial role in the ascent of the launch vehicle, propelling it from the atmosphere to the deep vacuum of outer space.

Key facts about the Vikram-1 Rocket:

It is named after the father of India’s space programme, Vikram Sarabhai and is a multi-stage launch vehicle with a capacity to place around 300 kg of payloads in low-earth orbit.
It has been built by Hyderabad-based Skyroot Aerospace. It is an all-carbon-fibre-bodied rocket that can place multiple satellites into orbit.
Being a solid-fuel rocket and using relatively simpler technologies would mean that launching this vehicle would require minimal infrastructure and that the rocket could be assembled and launched within 24 hours from any site.

Directive Principles of State Policy Constitution of India

The Constitution of India includes Directive Principles of State Policy (DPSP) in Part IV (Articles 36-51).

They aim to establish social, economic, and political justice in the country and promote the welfare of the people. Although not enforceable by courts, they serve as a moral and political compass for the government. Here are some key provisions of the DPSP in the Constitution of India: 1.

Social Justice: The state shall endeavor to promote the welfare of the people by securing and protecting a social order in which social, economic, and p...
