The article on Sally Ride, astronaut, under her PERSONAL LIFE uses pronouns that detract from and lend ambiguity to the communication.  It's unclear whose sister spoke up. I am suggestion that in lieu of pronouns (and perhaps risking some redundancy) proper names be used so there is conclusively no confusion on who is being (currently) referenced by the pronouns.
