Today on CNN 10, we head to Russia where presidential elections are underway. Then, we have liftoff as SpaceX launches the most powerful rocket, Starship, into space on a third test flight attempt. Next, we recognize two influential women figures during Women's History Month: environmental activist Wangari Maathai and physicist Lise Meitner. And before you go, we meet a "groggy doggy" who would rather have his beauty sleep than wake up to start his shift watching over sheep at a Virginia farm. All that and more on this episode of CNN 10.
