Her trip was made possible by a private programme called Project Juno, and paid for jointly by the USSR and a consortium of British companies.
The former chemist is being honoured for her services to science and technology educational outreach.
Also being honoured is co-founder and joint chief executive of the Ambassador Theatre Group, Rosemary Squire, who receives a damehood for her services to theatre and philanthropy.
Former rugby union referee Edward Morrison will be made an OBE for his services to the sport.
