Where can I see the project roadmap on the site?

I can not find. White paper is also not yet available on the site.

The roadmap is located in the crowdsale section of the site

https://atronocom.io/crowdsale/

All project plans for the near future are listed here.

Sun plans end in March 2020?

Where can I see further project development plans?

This roadmap describes the plans that must be completed first. After crowdsale is completed, Atronocom team will develop new plans
