The characters of the book
The main characters of the book "Project hail mary" are called Michael, Mary, and Frank. They are all astronauts. Mary is the only woman in the group. All three of them are very busy with their work, so they don't have the time to look after themselves.
Michael, for example, has grown so fat that he can no longer fit into the spacesuit. Mary has got a scar on her body because of her last space mission, so she can't go on another space mission. They all want to save the world, but they want to save themselves first.
Frank is the leader of the team. Michael and Mary are members of the group. They are the most experienced people in the group. They are good at what they do.
There are other people in the group, too. Their names are Nora, Adam, and Paula. They are all experienced astronauts. They also have a lot of experience of other kinds of work that is necessary for the successful completion of the mission.
Frank has a theory that a big asteroid will soon hit the Earth. Mary and Michael think that he is a dreamer who has been reading too many science fiction stories. But the real danger strikes. Frank's theory turns out to be right. He is right. And now they have to save the world.
