As space travel becomes more common, it is important to consider the impacts of space flight and altered gravity on the human body. Led by Dr. Ana Diaz Artiles, researchers at Texas A&M University are studying some of those impacts, specifically effects on the eye. The findings are published in the journal npj Microgravity.

Gravitational changes experienced by astronauts during space travel can cause fluids within the body to shift. This can cause changes to the cardiovascular system, including vessels in and around the eyes.

As the commercialization of space flight becomes more common and individual space travel increases, astronauts will not be the only ones experiencing these changes. Individuals traveling to space with commercial companies may not be as fit or healthy as astronauts, making it even more important to understand the role that fluid shift plays in cardiovascular and eye health.

"When we experience microgravity conditions, we see changes in the cardiovascular system because gravity is not pulling down all these fluids as it typically does on Earth when we are in an upright position," said Diaz Artiles, an assistant professor in the Department of Aerospace Engineering and a Williams Brothers Construction Company Faculty Fellow.

A late scrub due to weather on June 18 means it will have been at least 12 days since SpaceX last lit up the Space Coast sky with a rocket launch, the longest run between launches in more than a year.

It's not for a lack of trying, though. Bad weather and a scrub as the countdown clock hit 0 last week led to SpaceX taking down a Falcon 9 rocket for a Starlink mission and switching it up with a Falcon 9 to launch a European TV satellite. The first try on Tuesday night, though, faced high winds at the launch site.

The SES 24 mission flying the ASTRA 1P communication satellite for Luxembourg-based communications company SES will now try to launch from Cape Canaveral Space Force Station's Space Launch Complex 40 on Wednesday during a two-hour, 49-minute window that opens at 5:25 p.m. The satellite will service TV markets in Germany, Spain and France.

Space Launch Delta 45's weather squadron forecasts only a 45% chance for good conditions for June 19.

If it does launch, the first-stage booster will be making its ninth flight and will aim for a landing downrange on the droneship.

In the coming decade, more people will go to space than ever before as human spaceflight enters a new era. NASA, the European Space Agency and other governmental agencies are partnering to develop crewed missions beyond the moon. At the same time, these agencies are collaborating with private companies using new technologies to drive down the price of space exploration.

Companies such as SpaceX, Blue Origin and Sierra Space have developed vehicles with reusable boosters, automated flight systems and lightweight materials to support these deep space missions.
