Leave it to the well-spoken and articulate Chris Hadfield to explain the importance of the space station in such poetic language. In this interview with NPR this week, Hadfield not only talks about how his recent Expedition to the ISS “went viral” but what else is going on in space besides making music videos.
Listen to the entire interview (7 and a half minutes) below, but the main points about the cost and utility of the ISS are….
WERTHEIMER: Do you think that’s important for the future of the program, to try to make a big extra effort to engage people, when we’re all so concerned about how much it all costs?
HADFIELD: You know, you can’t support the Space Station if you don’t know it exists. People have to know it exists, and see that it serves us at a lot of different levels, everything from understanding how to extinguish flame inside a wall, to the fact that you can record a David Bowie video in weightlessness and thrill, you know, tens of millions of people. All of that is possible up there. You need to make an effort to engage people in it and show them that this is, of all the things that we’re choosing to do with our tax dollars, this is one of the really cool, interesting things. And then they can make their own decision as to whether we should support it or not.
WERTHEIMER: The science has always been interesting, of course, but the thing that I think most people on Earth think about is not going to the Space Station, but going past the Space Station, traveling in space.
HADFIELD: For thousands of years, people sailed in rivers and up and down the coast. And only after they had invented so many things – navigation, food supply, really good sails, ships they could count on – did they turn away from shore and go over the horizon. They had to invent a lot of things first. There may have been people that went over the horizon, but they probably didn’t come back, because they didn’t know enough stuff yet.
And we are, right now, sailing within the sight of shore. We’re trying to figure out all those things as we go around the world, so that when you do fire your engines and go 40 percent faster and leave the Earth, and it’s been really hard to turn around and come back, that you can count on your sailing ship, that it’s going to keep you alive and get you where you want to go. And that’s what the Space Station is. It is the crucible where we’re learning and testing and figuring out all those things so that we can go further, which is inevitably what we’re going to do.

The privately built Cygnus Pressurized Cargo Module (PCM) was developed by Orbital Sciences Corp. & Thales Alenia Space under the Commercial Resupply Services (CRS) cargo transport contract with NASA.
Universe Today took an exclusive look at the unmanned Cygnus cargo carrier housed inside the high bay facility where the vehicle is being processed for flight during a visit at NASA Wallops.
Cygnus is an essential lifeline to stock the station with all manner of equipment, science experiments, food, clothing, spare parts and gear for the international crew of six astronauts and cosmonauts.

The Cygnus PCM is manufactured by Thales Alenia Space at their production facility in Turin, Italy under a subcontract from Orbital.
The design is based on the Multi Purpose Logistic Module (MPLM) space shuttle cargo transporter.
The standard version has an internal volume of 18.9 cubic meters and can carry a total cargo mass of 2000 kg.
It was encased inside a special shipping container and flown from Italy to the US aboard an Antonov An-124 aircraft on July 17. The massive An-124 is the world’s second largest operating cargo aircraft.
After unloading from the An-124 and movement into a clean room high bay at Wallops Processing Building H-100, the shipping crate’s cover was raised using a 20 ton bridge crane. The PCM was unloaded and likewise gently craned over to an adjacent high bay work stand for flight processing.

Approximately a month and a half before launch, technicians mate the Cygnus PCM to the Service Module (SM) which houses the spacecraft’s avionics, propulsion and power systems and propels the combined vehicle to berth at the ISS.
The Cygnus SM is built by Orbital at their manufacturing facility in Dulles, VA., and shipped to Wallops for integration with the PCM in the processing building.
This particular vehicle is actually the second PCM bound for the ISS, but will be the first of eight operational cargo delivery runs to the space station over the next few years.
The first PCM to fly is set to blast-off on a Demonstration Mission (COTS 1) to the ISS in some six weeks on Sept. 14 atop Orbital’s privately developed Antares rocket. It is also in the midst of flight processing at Wallops inside a different building known as the Horizontal Integration Facility (HIF) where it is integrated with the Antares rocket.

Orbital says the Cygnus Demo vehicle is already fueled and will be loaded with about 1550 kg of cargo for the station crew.
The purpose of the demonstration flight is to prove that the unmanned spacecraft can safely and successfully rendezvous and dock with the orbiting outpost. The flight objectives are quite similar to the initial cargo delivery test flights successfully accomplished by Orbital’s commercial rival, SpaceX.
All of Orbital’s ISS cargo resupply missions will occur from the Mid-Atlantic Regional Spaceport’s (MARS) pad 0A at Wallops.

This past spring on April 21, Orbital successfully launched the 1st test flight of the Antares rocket. Read my articles here and here.
Orbital’s Antares/Cygnus system is similar in scope to the SpaceX Falcon 9/Dragon system.
Both firms won lucrative NASA contracts to deliver approximately 20,000 kilograms each of supplies and science equipment to the ISS during some 20 flights over the coming 3 to 4 years.

The goal of NASA’s CRS initiative is to achieve safe, reliable and cost-effective transportation to and from the ISS and low-Earth orbit (LEO) as a replacement for NASA’s now retired Space Shuttle Program.
Orbital’s contract with NASA for at least eight Antares/Cygnus resupply missions to the ISS is worth $1.9 Billion.

Today’s spacewalk at the International Space Station was cut short due to a water leak inside astronaut Luca Parmitano’s spacesuit. At one point, there was so much water inside Parmitano’s ears and around his face that he couldn’t hear or speak to communicate with the other astronauts. “Squeeze my hand if you’re fine,” fellow EVA member Chris Cassidy said to Parmitano.
What was supposed to be a 6-7 hour spacewalk lasted only 1 hour and 32 minutes after the leak occurred.
If you don’t think a little water could be a problem inside a spacesuit, recall how Chris Hadfield showed how water clung to his eyes in a simulated “cry,” or continued to cling to a washcloth even though it was being wrung out (see video below). The water inside Parmitano’s helmet literally surrounded and clung to his face and head.
“He looks miserable, but is OK,” the crew told Mission Control after they quickly removed Parmitano’s helmet and toweled off his face and head.
NASA TV said the cause of the leak in the helmet was “not readily identifiable,” but Parmitano appeared to be examining the drink bag that was inside his helmet shortly after the two astronauts got inside and were removed from their suits. However, just a short time later, Cassidy told Mission Control that Parmitano said the “water tasted really funny,” so it was likely not from the drink bag, and was perhaps the iodinated water from the crew’s liquid-cooled undergarments. But Cassidy also said Parmitano’s torso was essentially dry, and that the source of water seemed to be around the back of his head.

NASA is still investigating the source of the leak, and will have followup discussions and medical conferences with the astronauts to find out more and to make sure Parmitano is OK.
The two astronauts were going to continue tasks from last week’s EVA: routing power and data cables for a new Russian laboratory module scheduled to be launched to the ISS late this year or early 2014. They also were going to reposition a wireless camera antenna on the station’s power truss and replace a camera on the external deck of the Japanese Kibo lab module.
But the spacewalkers only completed one task before the leak became a problem. This was the second shortest spacewalk on record; on June 24, 2004, pressure problem in Mike Fincke’s spacesuit prompted an abbreviated 14-minute EVA.

The @SpaceShuttleAlmanac Twitter feed may have provided the best analogy of what Parmitano was experiencing during the leak: “Imagine having a fishbowl on your head with a half a litre of water sticking to your face, ears and nose. Then imagine you can’t take the fishbowl off your head for a minimum of 20 minutes, feel the panic?”
This was the 171st EVA for station construction and maintenance. NASA said nothing critical to station will be affected as a result of cutting the space walk short. Likely another EVA will be scheduled for the tasks.
NASA will be holding a news conference later today to provide more information.
Last week, astronaut Karen Nyberg shared via video how she washes her long hair in space. Since about 1.5 million people have watched it, NASA decided to give equal time to the bald guy in space, Luca Parmitano. As I stated last week, obviously, Parmitano uses a different method than Nyberg. Note it takes about 3 minutes for Nyberg to wash her hair, while it takes Parmitano less than a minute.
Those of us with long tresses have wondered, how do you wash that floating mass of hair in space? Astronaut and Expedition 36 crewmember Karen Nyberg provides a how-to video direct from the International Space Station. Obviously, Nyberg’s crewmate Luca Parmitano doesn’t have to go through this process.
But wash your hair today, have drinking water or coffee tomorrow!

Want a “you are there” view of today’s EVA that took place outside the International Space Station? Take a look at this great video of astronaut Chris Cassidy getting a ride on the station’s Canadarm-2 to make repairs and prepare for a new Russian laboratory. There are several great “over the shoulder” views during this short highlight video.
During their 6-hour and 7-minute spacewalk, Cassidy of NASA and Luca Parmitano of the European Space Agency worked on replacing a failed communications receiver, relocating grapple bars for future spacewalks and stringing cables for the when the Russian laboratory module arrives later this year.
The Ku-band communications receiver replaces one that failed last December. There was already a redundant backup system now in use, and this new one will become the backup.
The new Russian lab, called Nauka, will replace the Pirs airlock. It is scheduled to launch on a Proton rocket booster late this year, although the flight could be delayed a bit until early next year as because of assembly delays in Russia.
This spacewalk was the first of two in as many weeks for the duo. They will again venture outside the Quest airlock on July 16 for more upgrades and repairs. This was Parmitano’s first spacewalk, and he has now become the first Italian astronaut to walk in space. Old pro Cassidy has now been on five spacewalks, and this was the 170th spacewalk in support of space station assembly and maintenance.

On Monday, two Russian cosmonauts conducted a 6-hour, 34-minute spacewalk to prepare for a new Russian module that will be launched later this year. Expedition 36 Flight Engineers Fyodor Yurchikhin and Alexander Misurkin also work on the first module ever launched for the ISS – the Zarya module which has been in space since 1998 – replacing an aging control panels located on the exterior.
The new lab will be a combination research facility, airlock and docking port, and is planned to launch late this year on a Proton rocket.
Watch video highlights of the EVA below:
This was the second of up to six Russian spacewalks planned for this year to prepare for the lab. Two U.S. spacewalks by NASA’s Chris Cassidy and Luca Parmitano of the European Space Agency are scheduled in July.
While Yurchikhin and Misurkin worked outside the ISS, the crew inside the ISS were separated and isolated from each other. Cassidy and station commander Pavel Vinogradov were sequestered in their Soyuz TMA-08M spacecraft that is attached to the Poisk module on the Russian segment due to the closure of hatches to the other passageways on the Russian side of the station which would have made the Soyuz inaccessible if there was an emergency. Parmitano and US astronaut Karen Nyberg were inside the U.S. segment of the station, and were free to move around since entry to their Soyuz vehicle (TMA-09M) was not blocked by hatch closures, since it is docked to the Rassvet module that is attached to the Zarya module.
NASA said the spacewalk was the 169th in support of space station assembly and maintenance, the sixth for Yurchikhin and the first for Misurkin.

Recall how during a space shuttle mission, the astronauts were awoken each day with music radioed up from Mission Control? Now, ESA has started a tradition of creating a music video to celebrate various events, such as the docking of their Automated Transfer Vehicle. The ATV-4, named Albert Einstein, will dock with the International Space Station on Saturday, June 15 at 13:46 UTC (9:46 a.m. EDT, and here’s a little hip hop to get you in the mood.
ESA teamed up with hip hop group Ugly Duckling for a super space remix of the song “Elevation.”
The connection to the group and this ATV mission was perfect, as the long-time DJ for Ugly Duckling goes under the stage name DJ Young Einstein. ESA liked the group because they are known for their ‘old-school’ hip-hop with an upbeat message and non-violent lyrics.
TATV-4 is ferrying a record cargo of 6.6 tons to the ISS – food, fuel, water, oxygen, science experiments and undisclosed special treats for the six-member crew on the space station.
