It is known that Canadian astronaut Chris Hadfield had caught the imaginations of thousands of people with videos, tweets and some spectacular pictures, while he was on-board the International Space Station (ISS).

But, it is being claimed by his son Evan Hadfield that the same was not a warily co-ordinated marketing campaign.

A blog has been written by Evan, wherein he has been refusing to the fact that ghostwriters had been used by his father. It was last month when an article in Blacklock's Reporter, an Ottawa-insider publication, had alleged him of doing so.

Documents had been gathered by the publication through the Access to Information Act. It was then said that the government was likely involved in the social media presence of Hadfield.

Evan Hadfield asserted that the facts had clearly been inflated by Blacklock's. It was possible that it was looking for some controversy when there was not any, actually.

He affirmed that the article had quite inflamed him at the time he read the same.

"Astronaut Chris Hadfield's seemingly spontaneous performances in space were the product of a three-year marketing campaign complete with CBC collaboration and occasional tweets ghostwritten by government employees, Blacklock's has learned", according to the article.
