It starts with two tributes to Dr Sally Ride, the first American women to travel into space.
In a NASA press release NASA Administrator Charles Bolden said:
Sally Ride broke barriers with grace and professionalism — and literally changed the face of America’s space program.
The nation has lost one of its finest leaders, teachers and explorers. Our thoughts and prayers are with Sally’s family and the many she inspired. She will be missed, but her star will always shine brightly.
Welcome aboard to another fine issue of Carnival of space, a collection of the best the astronomy community has to offer.
