Plea for help from Russian Space agency as solo traveller and faithful dog are lost in the Arctic

The 62-year-old adventurer and his dog Yankie were seen in July at Cape Sterligov, a headland in the Kara Sea, by the chief of the polar station at this lonely outpost on the Taymyr peninsula.

This meant he had successfully navigated the Yenisei River and beyond with his small boat powered by a Honda engine.

Sergey reached the port of Dikson on 19 July, but then the trail runs cold. 

He did not pass Cape Chelyuskin, the northernmost point of Eurasia, which was on his route to Golomyanniy island, it is believed.

Sergey's distraught family went to police at the end of October, after it became clear that he had missed all planned deadlines for his return.

Sergey and his beloved Jagdterrier left to conquer the Arctic early in July. 

This was his first trip on the open sea of such complexity, and Sergey prepared himself well. 

He took two satellite phones, a radio transmitter, a rifle and food supply as well as appropriate clothing. 

Igor Chapalov, a friend of the extreme traveller and solo explorer himself, said Golubev may have hit some complications so that he could not continue his route. 

The chances of finding him may seem bleak, but those who know him are not giving up. 

‘There is still a 10 per cent chance that he decided to camp for winter because possibly his boat went missing, or he lost either his phones, or the rifle, or everything,’ Chapalov told Krasnoyarsk TV7. 

His friends and family said that Sergey had planned to reach Cape Arctic, on Severnaya Zemlya, a 37,000-square-kilometre archipelago off Siberia's Taymyr Peninsula, and specifically Golomyanniy island.

Given the vast snowy lands of the Actic the search is obviously extremely difficult. 

But Chapalov hopes the Russian Space Agency might be able to trace his route from his last known sighting from satellite images.

In case Sergey is stranded and - hopefully - alive, this may enable his rescue.
