What is sales prospecting?

Sales prospecting is a sales person's #1 job. Only when a sales person is in front of a viable prospect - and by viable I mean they have the interest, ability and desire to purchase what you and/or your company is offering - can a sale be made. And making sales is how companies grow. If your company does not grow you are out of work. So looking for people that can buy what you are selling is "Sales Prospecting."
