you know what to do that we have to look at the immune system because the immune system is involved in a cardiovascular aging process. yes here on earth and why do we use the arrow gravity because weightlessness imitates the aging process. the team has discovered that the body ages faster in zero gravity the problem is especially obvious in long term missions like scott kelly s the american astronaut spent a year on the international space station longer than anyone else on his return he was physically incapable of leaving the capsule without assistance it was thought to be a muscle problem but furnish that first says that s not quite the case what would you say that i know that even if his leg muscles and everything were still working you still wouldn t be able to climb out because the blood vessels especially here in the carotid artery change so much over time he couldn t regulate his blood pressure effectively. the researchers who small tubes called tissue chips to

astronaut, and it was the second stage of the booster rocket that seemed to have a technical malfunction. i listened to the broadcast as it what going on, and it was amazing to hear how calm the astronauts were when they learned the rocket was malfunctioning, and then it seems the parachutes deployed and landed 250 miles away from where the rocket took off. there s helicopters on the way to the site, and the astronauts are alive and in good condition. there are crews on the scene right now. russian paratroopers on their way to get to the site as fast as possible. just a quick word, though, the american astronaut, he has only
camerota in new york because there s still more breaking news. here s another breaking story. there s an emergency aboard a spacecraft carrying an american astronaut and russian cosmonaut, and they had to avoid a launch after a failure of one of the rockets. let s get to fred who is live in moscow with the developing story. fred, what happened? this is developing as we speak. this could have been more catastrophic as it was. we know from incidents in the past how small the margin of error is when you are shooting people into space. here s what we know so far. this rocket took off with the american astronaut and russian
