ROCKET SCIENCE
Dragon Splashes Down to Complete Resupply Mission
by Staff Writers
Houston TX (SPX) Jul 07, 2017


The Dragon spacecraft launched June 3 on a SpaceX Falcon 9 rocket from historic Launch Complex 39A at NASA's Kennedy Space Center in Florida, and arrived at the station June 5.

SpaceX's Dragon cargo craft splashed down in the Pacific Ocean at 8:12 a.m. EDT, west of Baja California and the recovery process is underway, marking the end of the company's eleventh contracted cargo resupply mission to the International Space Station for NASA.

Expedition 52 astronauts Jack Fischer and Peggy Whitson of NASA released the SpaceX Dragon cargo spacecraft from the International Space Station's robotic arm right on schedule, at 2:41 a.m.

A variety of technological and biological studies are returning in Dragon. The Fruit Fly Lab-02 experiment seeks to better understand the effects of prolonged exposure to microgravity on the heart.

Flies are small, with a well-known genetic make-up, and age rapidly, making them good models for heart function studies. This experiment could significantly advance understanding of how spaceflight affects the cardiovascular system and could help develop countermeasures to help astronauts.

Samples from the Systemic Therapy of NELL-1 for osteoporosis will return as part of an investigation using rodents as models to test a new drug that can both rebuild bone and block further bone loss, improving crew health.

When people and animals spend extended periods of time in space, they experience bone density loss, or osteoporosis. In-flight countermeasures, such as exercise, prevent it from getting worse, but there isn't a therapy on Earth or in space that can restore bone density.

The results from this ISS National Laboratory-sponsored investigation is built on previous research also supported by the National Institutes for Health and could lead to new drugs for treating bone density loss in millions of people on Earth.

The Cardiac Stem Cells experiment investigated how microgravity affects stem cells and the factors that govern stem cell activity. The study focuses on understanding cardiac stem cell function, which has numerous biomedical and commercial applications. Scientists will also look to apply new knowledge to the design of new stem cell therapies to treat heart disease on Earth.

After two delays, SpaceX launches broadband satellite for IntelSat
Cape Canaveral (AFP) July 5, 2017
SpaceX on Wednesday deployed a broadband communications satellite for IntelSat, after twice ditching launch plans in the final seconds before liftoff earlier this week. The satellite, known as IntelSat 35e, soared into the blue sky over Cape Canaveral at 7:38 pm (2338 GMT), riding a Falcon 9 rocket to a distant, geostationary orbit. The force required to send the payload to space meant S ... read more
