Experiments rocket to space station
CAPE CANAVERAL — A SpaceX capsule rocketed to the International Space Station on Monday, carrying tons of science research, plus ice cream.
As has become customary on these cargo flights, SpaceX landed its leftover booster back at Cape Canaveral shortly after liftoff, a key to its long-term effort to recycle rockets and reduce costs.
“Gorgeous day, spectacular launch,” said Dan Hartman, NASA’s deputy manager of the space station program.
Experiments make up most of the 6,400 pounds of cargo, which should reach the orbiting lab Wednesday. That includes 20 mice that will return alive inside the SpaceX Dragon capsule in about a month.
The Dragon is also doubling as an ice cream truck this time.
There was extra freezer space, so NASA packed little cups of vanilla, chocolate and birthday cake ice cream, as well as ice cream candy bars. Those treats should be especially welcomed by U.S. astronaut Peggy Whitson, in orbit since November. She’s due back at the beginning of September. Newly arrived U.S. spaceman Randolph Bresnik turns 50 next month.
The space station was zooming 250 miles above the Atlantic, just off Nova Scotia, when the Falcon took flight.
It was the 14th successful booster landing for SpaceX and the sixth on the giant X at the company’s touchdown spot at Cape Canaveral Air Force Station, just a few miles from its NASA-leased pad at Kennedy Space Center.
“It’s right on the bull’s-eye, and a very soft touchdown,” said SpaceX’s Hans Koenigsmann.
The mice on board are part of a study of visual problems suffered in space by some male astronauts. Scientists will study the pressure in the animals’ eyes, as well as the movement of fluid in their brains. Thirty days for mice in space is comparable to three years for humans, according to Florida State University’s Michael Delp, who’s in charge of the experiment. The study may help explain why female astronauts don’t have this vision problem, which can linger long after spaceflight, he added.
