CAPE CANAVERAL, FL – SpaceX launched a 3-ton shipment to the International Space Station on Thursday, including “mighty mice” for a muscle study, a robot sensitive to astronauts' emotions and a miniature version of a brewery's malt house.
The Dragon capsule also is delivering holiday goodies for the six station residents. NASA's Kenny Todd isn't giving any hints, but said, “Santa's sleigh, I think, is certified for the vacuum of space.”
The recycled capsule should arrive Sunday.
The Falcon rocket blasted off from Cape Canaveral a day late because of high winds. SpaceX recovered the new booster on a barge just off the coast in the Atlantic several minutes following liftoff so it could be reused. SpaceX employees in Southern California cheered when the booster landed, and again a few minutes later when the capsule reached orbit.
This is SpaceX's 19th supply run for NASA.
Forty mice are aboard, including eight "mighty mice" with twice the muscle mass of ordinary mice, according to the experiment's chief scientist, Dr. Se-Jin Lee of the Jackson Laboratory in Farmington, Connecticut.
Researchers plan to bulk up some of the non-mighty space mice during or after their month-long flight in an attempt to build up muscle and bone. This therapy could one day help astronauts stay fit on lengthy space trips, said Lee and Dr. Emily Germain-Lee of Connecticut Children's Medical Center.
Before and after liftoff, the couple sang part of the theme song to the mid-20th century superhero TV cartoon “Mighty Mouse"' and even had others joining in at the launch site.
