Space to Ground: Crew Call: 05/21/2021

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station.

What is said in the film

"houston, station on space to ground. " welcome to space to ground, I am kayla lafrance. From science experiments and in-flight maintenance, the crew onboard the space station has been hard at work this week. Jaxa astronaut aki hoshide donned a bio-monitor this week to be a participant in the canadian space agencies vascular aging study. The bio-monitor is a wearable technology system designed to look and feel as comfortable as a typical snug shirt, but in reality it is actually monitoring the wearers heart rate, activity level, and breathing rate.

The data gathered from the bio-monitor, along with data from ultrasounds and blood tests, will be sent back to researchers as part of the vascular aging experiment. Which is the 3rd of a series of scientific experiments that studies the effects of weightlessness on astronauts' blood vessels and hearts on board the international space station. The vascular aging study is looking at issues known to pose risks to astronauts' health, like radiation and insulin resistance. Studying the responses of the cardiovascular system in space better equips us to understand how our arteries age here on earth. On monday, nasa announced the 4th and final member for the upcoming nasa spacex crew-3 mission to the iss.

Nasa astronaut kayla barron was selected to serve as a mission specialist for the crew-3 mission which is targeted to launch as early as october 23. Barron will be joining crewmembers nasa astronauts raja chari and tom marshburn as the mission’s commander and pilot respectively, and european space agency astronaut matthias maurer, who also will serve as a mission specialist. This will be the first spaceflight for barron, who became a nasa astronaut in january 2020 after completing two years of training. This week’s question come ashlyn, a 5th grader from new york who wanted to know what happens to garbage on the iss? That is a great question!

There’s no trash pickup in space, which means that the crew has to store their trash in special bags called jettison stowage bags. After a cargo vehicle arrives at the station, the crew will load all of their trash bags, foam cushions and other items to be removed. These vehicles will depart filled with thousands of pounds of disposable items, ultimately burning up in the atmosphere during reentry. The nanoracks bishop airlock, which was recently installed on station, also has the ability to jettison trash right from the orbiting lab to be burned up in the atmosphere. And that’s space to ground for this week.

Thanks for watching. We’ll see you next week.
