Crew-1 Takes Questions Thursday, Station Busy with Human Research

The SpaceX Crew-1 astronauts are back in Houston after splashing down in the Gulf of Mexico early Sunday completing a 168-day mission. The quartet will have a news conference on NASA TV then participate in a Facebook Live event on Thursday.

NASA astronauts Michael Hopkins, Victor Glover and Victor Glover with Japan Aerospace Exploration Agency astronaut Soichi Noguchi will talk to reporters and answer social media questions on Thursday. The NASA TV news conference starts at 3:45 p.m. EDT. The Facebook Live event will begin at 4:35 p.m. and last 20 minutes.

Back in space, seven Expedition 65 crew members will be orbiting Earth on the International Space Station until October. The five astronauts and two cosmonauts are participating in a variety of research today to understand how living in space affects the human body.

Microbes can change characteristics in microgravity and scientists are testing anti-microbial coatings on the station. Today, an astronaut touched a sample with the coating representing a high-touch surface. The sample was stowed in a science freezer and will be returned later to Earth for analysis. Results could mitigate health issues on spacecraft and planetary surfaces.

The Celestial Immunity study taking place today on the orbiting lab is exploring how the immune system adapts to weightlessness. The astronauts look at human blood cells for age-associated effects giving scientists insights into the development of new vaccines and drugs to treat diseases.

Some of the crewmates also had ultrasound scans today to understand how long-term microgravity affects their muscle's biochemical properties such as tone, stiffness and elasticity. Samples, including blood, saliva and urine, were also collected and stowed for the Standard Measures and Repository biology studies.
