SpaceX successfully launches Falcon 9 rocket for resupply mission to the International Space Station

The launch was originally scheduled for 11:39 a.m. Saturday from Kennedy Space Center, but due to inclement weather in the recovery area the launch was scrubbed.

Sunday’s launch marks the 100th successful flight of the Falcon 9 rocket. Today’s launch also marks the 68th successful first stage recovery, as well as the 35th successful landing on the Of Course I Still Love You droneship.

After a success separation, the Dragon spacecraft will now head toward the International Space Station, and will autonomously dock with the ISS Monday around 1:30 p.m.

As well as bringing supplies to the ISS, the out-of-this-world mission may help University of Florida researchers understand why adults lose muscle strength as they age.

The experiment was carried to the ISS inside the Falcon 9 rocket which launched from the Kennedy Space Center on Sunday.

Researchers said the lab for the experiment is about the size of a shoe box. Inside is human tissue in chip form.

“We’ve actually created them as a three-dimensional muscle,” Dr. Siobhan Malany with UF Health said.

In space, astronauts experience extreme muscle weakness. Those same muscle changes happen to people on Earth as we age, but it happens at a much slower pace. So, researchers said, if you’re in the business of studying age-related occurrences, the best place to do it is in space.

The researchers will study how those muscle chips decline at that sped-up pace in space. The data collected in orbit will then return to Central Florida and help in the development of new therapies for age-related muscle loss on Earth.
