Our day started in a way that was a lot of fun: Early in the morning, housemate Alex Carney and I were taken to a building where they have the astronaut exercise machines. We thought we were going to get to see the machines again and maybe climb on them, but it was a lot more amazing than that.
They have two treadmills and a “weightlifting” machine. We started with COLBERT (which actually does stand for something – Combined Operational Load Bearing External Resistance Treadmill). We not only got to run on it but to use a harness attached with bungees to it, just like you’d do it on board the International Space Station. It was tiring but a lot of fun.
As a little bonus, the harness we got to use is the one that astronaut Nicole Stott (@Astro_Nicole) used on the station. Then we moved on to the Advanced Resistive Exercise Device, or ARED, which is basically a weightlifting machine. We got to do a couple of squats on it. It was not easy, but for a couple of reps it was exciting.
That afternoon we traveled to Galveston to visit the University of Texas Medical Branch, where we had lunch and a few presentations about space medicine. We heard about what life in space can look like and about the effects of space travel in psychology. These were quite interesting, and they got us thinking about the biological aspects of our mission in a completely different way.
We also got to see a few of the center's labs. They talked to us about experiments such as artificial DNA synthesizing, and we got to see the machines with which they work. It was in the same building where they give all the medical tests to see if you are fit to travel to space – it's the only facility that can do it.
Overall, it was an interesting day. To finish it nicely, we had dinner with our host family in Galveston and then we drove back and "geeked out" for a while in a bookstore (a good one, not like the small ones we have back at home).
"The Hubble Space Telescope captured a crowd of stars that looks rather like a stadium darkened before a show, lit only by the flashbulbs of the audience’s cameras. Yet the many stars of this object, known as Messier 107, are not a fleeting phenomenon, at least by human reckoning of time - these ancient stars have gleamed for many billions of years.
Messier 107 is one of more than 150 globular star clusters found around the disc of the Milky Way galaxy. These spherical collections each contain hundreds of thousands of extremely old stars and are among the oldest objects in the Milky Way. The origin of globular clusters and their impact on galactic evolution remains somewhat unclear, so astronomers continue to study them.
Messier 107 can be found in the constellation of Ophiuchus (The Serpent Bearer) and is located about 20,000 light-years from our solar system.
French astronomer Pierre Méchain first noted the object in 1782, and British astronomer William Herschel documented it independently a year later. A Canadian astronomer, Helen Sawyer Hogg, added Messier 107 to Charles Messier's famous astronomical catalogue in 1947.
