  • recently this happened capture confront SpaceX launched its crew dragon marking

  • the first time that a commercially built crew capsule launched from American soil

  • this is exciting all on its own but this upcoming Soyuz launch could also mark

  • the end of an era and what could be the last time Americans are sent to space in

  • a country other than their own expedition 5960 is expected to launch on

  • march 14th from the balcony or cosmodrome in kazakhstan ferrying the

  • new crew to the ISS including astronauts from October's failed abort mission the

  • two astronauts in one cosmonaut will be joining the crew already aboard the ISS

  • working on roughly 250 experiments to further our understanding of the human

  • body test new technology and even try to further wrap our brains around what time

  • means in space this latest mission will be on a Soyuz ms 12 spacecraft carrying

  • a three-person crew alexey ovchinin of the russian space agency Roscosmos NASA

  • astronauts Christina hammock coke and Nick Hague 4ov Keenan and Hague this is

  • their second attempt to make it to the ISS on October 11th 2018 the pair were

  • headed for a routine trip to the space station on a Soyuz rocket but two

  • minutes after liftoff a problem occurred during the separation of one of the

  • Rockets strap-on boosters forcing them to perform an emergency landing via

  • ballistic re-entry which sounds scary and is scary but it's actually the only

  • way astronauts used to re-enter at the beginnings of human space travel

  • since then ovchinin and Hague have been retrained and are prepared for

  • expedition 59 60 we got in touch with Hague currently stationed in Star City

  • Russia and spoke to him about his feelings of

  • heading back after only a few months well you know if you asked me a year ago

  • if I'd be in this position I could have never imagined it so it's a little bit

  • surreal being able to have another opportunity this quickly but I feel very

  • fortunate for the opportunity to be able to get up there and you know finally get

  • to doing the mission that I've been training for at NASA for the last five

  • years expedition 5960 will be making history

  • as they will be on board when the first Commercial Crew vehicles are scheduled

  • to arrive at the ISS having launched from Cape Canaveral in Florida do you

  • hasn't launched astronauts into space from its own soil since 2011

  • since then astronauts have been ferried to and from Earth via Russian Soyuz

  • rockets but this agreement is due to run out by the end of 2019 now there's a

  • chance that they may have the opportunity to buy more seats but the

  • overall goal is to get back to launching from the US so why did the u.s. stop

  • ferrying its astronauts to space officially named the space

  • transportation system NASA's Space Shuttle program had its first flight on

  • April 12th 1981 the space shuttle program was the world's first reusable

  • rocket shuttling astronauts repairing satellites and even helping to build the

  • ISS during its reign the program had five space shuttles that flew a total of

  • 135 missions but by 2011 one estimate put the average cost per trip to roughly

  • 1.5 billion dollars so after 30 years of service NASA decided to retire the

  • program since then the US has been entirely dependent on Russia as the

  • Soyuz is the only spacecraft available to transport crews to the ISS and

  • they're pretty reliable the Soyuz is the longest operational manned spacecraft in

  • history although it's expensive the u.s. currently pays 81 million dollars per

  • seat for its astronauts two hits arrive which is why in 2014 NASA decided to

  • spend its coin in the private sector awarding both SpaceX and Boeing with

  • contracts to build spacecraft that could shuttle astronauts in the long term this

  • also means that NASA has more resources available to tackle challenges like deep

  • space exploration and getting to Mars to be ready for the task

  • SpaceX built its crew Dragon spacecraft that sits atop a falcon 9 its first test

  • flight dubbed demonstration 1 launched on March 2nd from Kennedy Space Center

  • making history as the first commercially made American spacecraft and rocket to

  • launch from the US after a day in Earth's orbit the capsule successfully

  • docked into the ISS delivering its spacesuit sensor wearing test device

  • named Ripley and roughly 180 kilograms of supplies

  • it remained docked for roughly five days before making its descent back to earth

  • splashing down into the Atlantic Ocean the other contract was awarded to Boeing

  • who cst-100 our liner capsule is scheduled for its

  • uncrewed test launch in April 2019 star liner is designed to be reused at least

  • ten times within the span of six months SpaceX and Boeing are continuing tests

  • but both have committed to manned space missions for later this year nASA has

  • already assigned the crew that will be heading up on these historic flights and

  • although crew dragon and star liner are built to carry seven passengers for

  • these first operational missions they'll carry only four crew members along with

  • roughly 100 kilograms of cargo by having different launch capabilities it

  • provides more launch options when needing to replan an aborted launch like

  • what happened to option and and Hague back in October this is going to make

  • the the program much more robust by having multiple means to launch from

  • whether it's the US whether it's Boeing or whether it's space X or or whether

  • it's on a Soyuz we've got all these ways to deliver crews so that if we do have a

  • problem we're more resilient and we don't have to bring down the size of the

  • crew of the station and put a you know a damper on the the research and we can

  • continue to move forward at the pace that we want to because at the end of

  • the day it's also about the really cool science happening on board the ISS right

  • now there are roughly 250 scientific experiments stationed aboard send up on

  • previous missions from different space agency partners looking to study various

  • aspects of life in space these experiments include how to grow food and

  • microgravity or monitoring lightning from space that happens every second or

  • how astronauts experience bone density loss during expeditions before heading

  • up the astronauts get training so they're able to handle the experiments

  • and they can even volunteer for them like the airway monitoring program sent

  • up by European Space Agency to help study astronauts loan function on the

  • ISS the study looks at the nitric oxide the astronauts breathe out which helps

  • in understanding the conditions of our lungs in space monitoring nitric oxide

  • levels helps to detect inflammatory diseases in the lungs like asthma

  • previous crews of astronauts have volunteered for the experiment like

  • German ESA astronaut Alexander Gerst and we also found that spaceflight triggers

  • a little bit the reaction of the lungs that are very close to what people have

  • when they have asthma so we can still breathe freely in space

  • it's not really stopping us from working and living there but we can still use

  • that little change to measure that right and we can understand it better because

  • we are in a much more controlled environment than it's possible down here

  • on earth for expedition 59 60 Nick Hague volunteered to be the human

  • test subject for the experiment so the benefit is when we get to the surface of

  • the Moon and there's dust and we know we had problems with lunar dust back in the

  • Apollo program we're going to be able to monitor the health of the astronauts

  • even better while they're working up there and and diagnose problems and

  • protect us while we're exploring the moon space is not easy it's a it's a

  • risky business it's always going to be a risky business but why do we do it

  • we've been up there for two decades on the space station in this amazing

  • international collaboration performing science collecting data so the

  • scientists on the ground can learn more about our planet

  • they can learn more about humans in our bodies and and how they behave they can

  • learn more about the universe that surrounds us and and all of that is

  • advancing humanity and so we accept those risks so that we can continue to

  • move forward and continue to expand the boundaries of what we know that's it's a

  • vital mission and we're doing it every day and I want people to when they see a

  • launch like that I want them to connect that launch with the importance of the

  • mission and that's just it there are so many launches happening every year so

  • many historic moments that aren't to be missed which is why we're committed to

  • bringing you more launch coverage than ever before that means we'll be there to

  • talk about the next crew Dragon launch Boeing Starliner

  • and the latest International moon missions if there's anything you'd like

  • us to cover on future missions let us know down in the comments and as always

  • thanks for watching seeker and I'll see you next time
