Is she also the first person to both walk in space (or just go to space) and also dive to the deepest point in the ocean? Or are there men or people from other countries that have done the same thing?
Her achievement was the first women to walk in space.
Have there been people who have walked in space, climbed Mount Everest, eaten heaps of hot dogs that have dived to the deepest point in the ocean.
Maybe, but unless they have eaten the most hot dogs, or were the first to climb Mount Everest, it's not really a headline.
