If it's from Clarke and Baxter (or, for that matter, anything by Clarke, with the exception of many of his short stories), I'd say it qualifies as Hard SF without even having to read it. Clarke is one of the most thorough and consistent hard SF writers that has ever been published, as far as I'm concerned.
I'm personally not fond of the Clarke-Baxter collaborations, myself, but they are based on Clarke's concepts and meticulous research.
