Scientists discover Billion Year Old River on Mars

Scientists from the European Space agency have discovered a river like structure on Mars by analyzing the 3D images of the Mars Express stereo camera. As per them, the region Reull Vallis bears a river-like structure which is believed to be formed when running water flowed in the distant martian past, cutting a steep-sided channel through the Promethei Terra Highlands before running on towards the floor of the vast Hellas basin.

The length of the river bed is around1500 kilometer which runs across the martian landscape.

These structures are thought to be formed by the passage of loose debris and ice during the ‘Amazonian’ period (which continues to this day) due to glacial flow along the channel.

The structures were originally carved by liquid water during the Hesperian period, which ended b/w 3.5 billion and 1.8 billion years ago.

Partial de-notification of RIL SEZ approved by the Govt

Union Government gave nod to Reliance Industries’ plans of de-notifying more than 40 % of its multi-product Special Economic Zone (SEZ) in Jamnagar subject to refund of all tax benefits it got for developing the area. However, the multi-product status of SEZ will remain intact as the total area would remain higher than the minimum required area of 1,000 hectares. The Govt has asked the company to get a no-objection-certificate from the Government of Gujarat.

The Board of Approval, which takes most decisions regarding the establishing and operation of SEZs, approved  RIL’s proposal to denotify 728.43 hectares, reducing the total area of its Jamnagar SEZ to 1035.72 hectares. However, the multi-product status of SEZ will remain intact as the total area would remain higher than the minimum required area of 1,000 hectares.

Why this de-notification?

RIL had applied for de-notifying about 40 % of its SEZ spanned over 1764.14 hectares as it intends to build new projects in the area with investments up to Rs 42,000 crore. Apart from Reliance, a number of SEZs have applied for de-notification and cancellation of approval following the Government’s decision to levy the minimum alternate tax and dividend distribution tax on SEZ investors.
