Hi Blaze, allow me, because Delhi pollution is a 4 decades old story, since 1980s; it was then just winter smog. Now it's denser and yes, growing; but the root problems are elsewhere.
1. It is heaviest around October when farmers in the adjoining states of Punjab and Haryana (big wheat producers) burn wheat / corn stalks after harvest. The downstream fire winds blow over Delhi. Government is looking at alternate use for stalks. Being seasonal used to be a reason previous governments remained inactive.
2. Yet, there is a basic underlying problem. The desert state of Rajasthan adjoins Delhi. There is always a spray of fine sand dust in the air that comes down on the homes and roads with the night dew. So around October, smoke particles clinging to sandy air; turns lethal.
3. There remain clusters of medium sized factories - that are not regulated but Delhi region has no heavy industries. Big business maintain just their liaison offices to work with government departments. It also head quarters the services sector; banking and financial and also a large base for IT firms.
4. Apart from these root causes, is traffic congestion. Miles of cars (meeting EPA standards) inch over 4 lane roads from the suburbs to the City. Metro rail is about a decade old - network inadequate.
Since you mentioned technology, the old factories and power plants in bordering states are getting phased out with modern plants that meet EPA regulations - a very slow process.
Status: Apart from the attention this issue is getting from the PMO / cabinet, India is also a signatory of the Climate Accord. We may expect some resolutions before next October, I believe.

W.r.t. OP's query on why India is investing in space; basically, the budget allocated on space is a tiny, un-noticeable sliver of our GDP.
If we refer back to the earlier thread under Science - India's moon lander - '
