In November, the S.S. Sally Ride Cygnus cargo spacecraft launched from NASA's Virginia site en route to the International Space Station
The spacecraft was named after the late Dr. Sally Ride, the first American woman in space.
Over 8,000 pounds of cargo were aboard the S.S. Sally Ride, including crew and scientific equipment.
Also inside was a United States flag with over 400 signatures from South Los Angeles students at Sally Ride Elementary School.
"It feels pretty exciting. What we wrote is in space now," said Andres Alvarez, a fifth grader at the school.
"I told my grandma on Nov. 7 my name is going to be in space," said Teshanti Cash, as fifth grader at the school.
The day of the launch, a local artist gifted the school with a painting of Dr. Ride.
The students also met Dr. Ride's sister, Bear Ride. A Los Angeles filmmaker, Steven Barber, organized this line up of surprises for the school.
