Nearly twelve hours after the threat of a leak of toxic ammonia forced the crew into a middle of the night evacuation from the US side of the International Space Station this morning (Jan. 14) and a hatch closure, top level managers from the partner space agencies gave the all clear and allowed the astronauts and cosmonauts to reopen access to the American portion of the orbiting outpost.
The six person crew hailing from the US, Italy and Russia were allowed to open the sealed hatch to the U.S. segment later this afternoon after it was determined that the ammonia leak was quite fortunately a false alarm.
No ammonia leak was actually detected. But the crew and mission control had to shut down some non essential station systems on the US segment in the interim.
All the Expedition 42 crew members were safe and in good health and never in danger, reported NASA.
The station crews and mission control teams must constantly be prepared and train for the unexpected and how to deal with potential emergencies, such as today’s threat of a serious chemical leak.
After a thorough review of the situation by the International Space Station mission management team, the crew were given the OK by flight controllers to head back.
They returned inside at 3:05 p.m. EST. Taking no chances, they wore protective masks and sampled the cabin atmosphere and reported no indications of any ammonia.
Fears that a leak had been detected resulted from the sounding of an alarm at around 4 a.m. EST.
The alarm forced Expedition 42 station commander Barry Wilmore and Flight Engineer Terry Virts of NASA and Flight Engineer Samantha Cristoforetti of the European Space Agency to don protective gas masks and move quickly into the Russian segment, sealing the hatch behind them to the US segment.
Inside the Russian segment, they joined the remainder of Expedition 42, namely cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia, also living and working aboard the ISS and rounding out the crew of four men and two women.
“The alarm is part of the environmental systems software on the station designed to monitor the cabin’s atmosphere. At the same time, the station’s protection software shut down one of two redundant cooling loops (Thermal Control System Loop B),” NASA said in an update.
Ammonia is a toxic substance used as a coolant in the stations complex cooling system that is an essential requirement to continued operation of the station.
Ammonia is a gas at room temperature that is extremely dangerous to inhale or when it comes in contact with skin, eyes and internal organs.
Precautions must be taken if a leak is feared in a confined space such as the ISS. It has about the same habitable volume as a four bedroom house.
As a professional chemist, I’ve worked frequently with ammonia in research and development labs and manufacturing plants and know the dangers firsthand. It can cause severe burns and irritations and worse.
There have been prior ammonia leaks aboard the ISS facility that forced a partial evacuation similar to today’s incident.
The ISS has been continuously occupied by humans for 15 years.
In the case of a life threatening emergency, the crew can rapidly abandon the station aboard the two docked Russian Soyuz capsules. They hold three persons each and serve as lifeboats.
Fortunately, the perceived ammonia leak this morning was not real and apparently was caused by a false alarm.
“This morning’s alarm is suspected to have been caused by a transient error message in one of the station’s computer relay systems, called a multiplexer-demultiplexer. A subsequent action to turn that relay box off and back on cleared the error message and the relay box is reported by flight controllers to be in good operating condition,” according to a NASA statement.
“Meanwhile, flight controllers are continuing to analyze data in an effort to determine what triggered the alarm that set today’s actions in motion.”
“Work to reactivate cooling loop B on the station will continue throughout the night and into the day Thursday. The crew members are expected to resume a normal complement of research activities on Thursday as well.”
Breaking News: A possible ammonia leak aboard the US side of the International Space Station (ISS) has forced a partial evacuation of the entire crew to the Russian side earlier this morning, Wednesday, Jan. 14.
All six crew members from the US, Italy and Russia are safe and in good shape at this time, says NASA and Roscosmos, the Russian Federal Space Agency.
Hatches between the US and Russian segments were sealed shut, pending further analysis.
Mission controllers are in the process of assessing whether it’s a real leak or a false alarm due to a faulty sensor or a computer problem. It’s not completely clear at this time.
The latest indications at 11 a.m. EST, Jan. 14, are that it may be a false alarm, says NASA.
“The security of a crew was guaranteed thanks to correct actions of the cosmonauts, astronauts and the crew of the Mission control centres in Moscow and Houston. Further plan of actions in the US modules must be prepared in Houston,” according to Roscosmos.
“For now NASA colleagues are analyzing situation”, – noted the head of Russian Mission Control Centre Maxim Matushin
Ammonia is a toxic substance used as a coolant in the stations complex cooling system that is an essential requirement to continued operation of the station.
There have been prior ammonia leaks aboard the ISS facility.
NASA announced that an alarm sounded in the US segment at about 4 a.m. EST. indicating a possible ammonia leak. As a result, all six Expedition 42 astronauts and cosmonauts evacuated the US segment.
“Flight controllers in Mission Control at NASA’s Johnson Space Center in Houston saw an increase in pressure in the station’s water loop for thermal control system B then later saw a cabin pressure increase that could be indicative of an ammonia leak in the worst case scenario,” according to a NASA announcement.
Therefore as a precaution after the alarm sounded earlier today, the crew was directed to isolate themselves in the Russian segment this morning while teams are evaluating the situation. The crew powered down non-essential equipment in the U.S. segment of the station according to established procedures, said NASA.
“In an exchange at 7:02 a.m. with Expedition 42 Commander Barry Wilmore of NASA, spacecraft communicator James Kelly said flight controllers were analyzing their data but said it is not yet known if the alarm was actually triggered by a leak or whether the situation was caused by a faulty sensor or by a problem in a computer relay box that sends data and commands to various systems on the station.”
The evacuation comes just two days after a commercial SpaceX Dragon cargo freighter successfully rendezvoused and berthed at the station on Monday, Jan. 11.
The ISS has been continuously occupied by humans for 15 years.
The current six person crew includes astronauts and cosmonauts from three nations; America, Russia and Italy including four men and two women serving aboard the massive orbiting lab complex.
They comprise Expedition 42 Commander Barry “Butch” Wilmore and Terry Virts from NASA, Samantha Cristoforetti from the European Space Agency (ESA) and cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia.
In the case of a life threatening emergency, the crew can rapidly abandon the station aboard the two docked Russian Soyuz capsules. They hold three persons each.

It’s sunrise from space – one of 16 that occur daily as the massive lab complex orbits the Earth about every 90 minutes while traveling swiftly at about 17,500 mph and an altitude of about 250 miles (400 kilometers).
Just stare in amazement at this gorgeous sunrise view of “Our Beautiful Earth” taken earlier today, Jan. 3, 2015, aboard the International Space Station (ISS) by crewmate and NASA astronaut Barry “Butch” Wilmore.
And smack dab in the middle is the Canadian-built robotic arm that will soon snatch a soaring Dragon!
Wilmore is the commander of the ISS Expedition 42 crew of six astronauts and cosmonauts hailing from three nations: America, Russia and Italy.
He is accompanied by astronauts Terry Virts from NASA and Samantha Cristoforetti from the European Space Agency (ESA) as well as by cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia.
All told the crew of four men and two women see 16 sunrises and 16 sunsets each day. During the daylight periods, temperatures reach 200 ºC, while temperatures plunge drastically during the night periods to -200 ºC.
Here’s another beautiful ISS sunset view captured on Christmas by Terry Virts:
Virts tweeted the picture and wrote: “Sunrise on Christmas morning – better than any present I could ask for!!!!”
Another treasure from Virts shows the many splendid glorious colors of Earth seen from space but not from the ground:
“In space you see intense colors, shades of blue that I’d never seen before,” says Virts from his social media accounts (http://instagram.com/astro_terry/) (http://instagram.com/iss).
“It’s been said a thousand times but it’s true: There are no borders that you can see from space, just one beautiful planet,” he says. “If everyone saw the Earth through that lens I think it would be a much better place.”
And many of the crews best images are taken from or of the 7 windowed Cupola.
Here’s an ultra cool shot of Butch waving Hi!
And they all eagerly await the launch and arrival of a Dragon! Indeed it’s the SpaceX cargo Dragon currently slated for liftoff in three days on Tuesday, Jan. 6.
Weather odds are currently 60% favorable for launch of the unmanned space station resupply ship on the SpaceX CRS-5 mission.
The launch was postponed from Dec. 19 when a static fire test of the first stage engines on Dec. 17 shut down prematurely.
A second static fire test of the SpaceX Falcon 9 went the full duration of approximately 3 seconds and cleared the path for a liftoff attempt after the Christmas holidays.
CRS-5 is slated to blast off at 6:20 a.m. EST Tuesday, Jan. 6, 2015, atop a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida.
NASA Television live launch coverage begins at 5 a.m. EST.
Assuming all goes well, Dragon will rendezvous at the ISS on Thursday, Jan. 8, for grappling and berthing by the astronauts maneuvering the 57 foot-long (22 m) Canadian built robotic arm.
Remember that you can always try and catch of glimpse of the ISS flying overhead by checking NASA’s Spot the Station website with a complete list of locations.
And don’t forget to catch up on the Christmas holiday and New Year’s 2015 imagery and festivities from the station crews in my recent stories – here, here and here.

Between the years of 1969 and 1972 the astronauts of the Apollo missions personally explored the alien landscape of the lunar surface, shuffling, bounding, digging, and roving across six sites on the Moon. In order to prepare for their off-world adventures though, they needed to practice extensively here on Earth so they would be ready to execute the long laundry lists of activities they were required to accomplish during their lunar EVAs. But where on Earth could they find the type of landscape that resembles the Moon’s rugged, dusty, and — most importantly — cratered terrain?
Enter the Cinder Lakes Crater Fields of Flagstaff, Arizona.
The Cinder Lakes Crater Fields northeast of Flagstaff, near the famous San Francisco peaks and just south of the Sunset Crater volcano, were used for Apollo-era training because of the inherently lunar-like volcanic landscape. LRV practice as well as hand tool geology and lunar morphology training were performed there, as well as ALSEP – Apollo Lunar Surface Experiment Package – placement and setup practice.
The photo above shows Apollo 15 astronauts Dave Scott and Jim Irwin driving a test LRV nicknamed Grover along the rim of a small “lunar crater.” (This particular exercise was performed on Nov. 2, 1970… 44 years ago today!)
Although the craters might look similar to the ones found on the Moon, they were actually created by the USGS in 1967 by digging holes and filling them with various amounts of explosives, which were detonated to simulate different-sized lunar impact craters. The human-made craters ranged in size from 5-40 feet (1.5-12 meters) in diameter.
The two crater field sites at Cinder Lakes were chosen because of the specific surface geology: a layer of basaltic cinders covering clay beds, left over from an eruption of the Sunset Crater volcano 950 years ago. After the explosions the excavated lighter clay material spread out from the blast craters and across the fields, like ejecta from actual meteorite impacts. A total of 497 craters were made within two sites comprising 2,000 square feet.
Detonations were done in series to simulate ejected debris from cratering events of different ages. And one of the areas of Cinder Lakes was designed to specifically replicate craters found within a particular region of the Apollo 11 Mare Tranquillitatis landing site.
Today only the largest craters can be distinguished at all in the publicly-accessible Cinder Lakes field, which has become popular with ATV enthusiasts. But a smaller field, fenced off to vehicles, still contains many of the original craters used by Apollo astronauts, softened by time and weather but still visible.
A couple of other areas were used as lunar analogue training fields as well, such as the nearby Merriam Crater and Black Canyon fields — the latter of which is now covered by a housing development. Geology field training exercises by Apollo astronauts were also performed at locations in Texas, New Mexico, Nevada, Oregon, Alaska, Idaho, Iceland, Mexico, the Grand Canyon, and the lava fields of Hawaii. But only in Arizona were actual craters made to specifically simulate the Moon!
Read more about the Cinder Lakes Crater Field in a presentation document (my main article source) by LPI’s Dr. David Kring, and you can find more recent photos of the Crater Lakes sites on this page by LPI’s Jim Scotti.
Cosmonauts Alexander Skvortsov and Oleg Artemyev are working outside at the International Space Station today! They will spend about 6.5 hours outside installing an antenna for data relays, relocating a cargo boom, swabbing samples from a window on the Zvezda service module and switching out science experiment gear. Watch live above.
This is milestone of sorts for ISS spacewalks: it is the 180th spacewalk in support of space station construction and maintenance since December 1998, when the Russian Zarya module was mated to the US Unity node. You can read what that first spacewalk was like in an interview with astronauts Bob Cabana: What Day 1 on the International Space Station Was like for the Astronauts.
And what’s going on inside the ISS today?
Pretty neat up here right now- two Russian crew mates are spacewalking but business as usual for me and @astro_alex
If you want to know who is who during the spacewalk, Skvortsov is wearing the Russian Orlan spacesuit with red stripes, and Artemyev’s has a spacesuit with blue stripes.
Boeing unveiled full scale mockup of their commercial CST-100 ‘Space Taxi’ on June 9, 2014 at its intended manufacturing facility at the Kennedy Space Center in Florida. The private vehicle will launch US astronauts to low Earth orbit and the ISS from US soil.

KENNEDY SPACE CENTER, FL – Boeing unveiled a full scale mockup of their CST-100 commercial ‘space taxi’ on Monday, June 9, at the new home of its future manufacturing site at the Kennedy Space Center located inside a refurbished facility that most recently was used to prepare NASA’s space shuttle orbiters for missions to the International Space Station (ISS).
The overriding goal is restart our country’s capability to reliably launch Americans to space from US territory as rapidly and efficiently as possible.
The CST-100 crew transporter was revealed at an invitation only ceremony and media event held on Monday, June 9, inside the gleaming white and completely renovated NASA processing hangar known as Orbiter Processing Facility-3 (OPF-3) – and attended by Universe Today.
The huge 64,000 square foot facility has sat dormant since the shuttles were retired following their final flight in July 2011 and which was commanded by Chris Ferguson, who now serves as director of Boeing’s Crew and Mission Operations.
Universe Today was invited to be on location at KSC for the big reveal ceremony headlining US Senator Bill Nelson (FL) and Boeing executives including shuttle commander Ferguson, for a first hand personal inspection of the private spaceship and also to crawl inside and sit in the seats of the capsule designed to carry American astronauts to the High Frontier as soon as 2017.
“Today we celebrate this commercial crew capsule,” said Sen. Nelson at the unveiling ceremony. “This vehicle is pretty fantastic and the push into space the CST-100 represents is historic.”
“We are at the dawn of a new Space Age. It’s complemented by the commercial activities going to and from the space station and then going outside low Earth orbit [with Orion], as we go to the ultimate goal of going to Mars. There is a bright future ahead.”
The purpose of developing and building the private CST-100 human rated capsule is to restore America’s capability to ferry astronauts to low-Earth orbit and the space station from American soil aboard American rockets, and thereby end our total dependency on the Russian Soyuz capsule for tickets to space and back.
Boeing’s philosophy is to make the CST-100 a commercial endeavor, as simple and cost effective as possible in order to quickly kick start US human spaceflight efforts. It’s based on proven technologies drawing on Boeing’s 100 year heritage in aviation and space.
“The CST-100, it’s a simple ride up to and back from space,” Ferguson told me. “So it doesn’t need to be luxurious. It’s an ascent and reentry vehicle – and that’s all!”
So the CST-100 is basically a taxi up and a taxi down from LEO. NASA’s complementary human space flight program involving the Orion crew vehicle is designed for deep space exploration.
Read my exclusive, in depth one-on-one interviews with Chris Ferguson – America’s last shuttle commander – about the CST-100; here and here.
The stairway to America’s future human access to space is at last literally taking shape from coast to coast.
Sen. Nelson, a strong space exploration advocate for NASA and who also flew on a space shuttle mission on Columbia back in January 1986, was the first person to climb the steps and enter the hatch leading to Boeing’s stairway to the heavens.
“This is harder to get in than the shuttle. But the seats are comfortable,” Nelson told me as he climbed inside the capsule and maneuvered his way into the center co-pilots seat.
Nelson received a personal guided tour of the CST-100 spaceship from Ferguson.
The capsule measures 4.56 meters (175 inches) in diameter.
The media including myself were also allowed to sit inside the capsule and given detailed briefings on Boeing ambitious plans for building a simple and cost effective astronaut transporter.
The vehicle includes five recliner seats, a hatch and windows, the pilots control console with several attached Samsung tablets for crew interfaces with wireless internet, a docking port to the ISS and ample space for 220 kilograms of cargo storage of an array of equipment, gear and science experiments depending on NASA’s allotment choices.
The interior features Boeing’s LED Sky Lighting with an adjustable blue hue based on its 787 Dreamliner airplanes to enhance the ambience for the crew.
Boeing is among a trio of American aerospace firms, including SpaceX and Sierra Nevada Corp, vying for the next round of contracts to build America’s ‘space taxi’ in a public/private partnership with NASA using seed money under the auspices of the agency’s Commercial Crew Program (CCP).
Since 2010, NASA has spent over $1.5 billion on the commercial crew effort.
Boeing has received approximately $600 million and is on target to complete all of NASA’s assigned CCP milestones in the current contract phase known as Commercial Crew Integrated Capability initiative (CCiCAP) by mid-2014.
Boeing’s CST-100 crew capsule reveal on June 9 comes just two weeks after SpaceX CEO Elon Musk’s Hollywoodesqe glitzy live show on May 29 – pulling the curtain off his firms ‘Dragon’ crew vehicle entry into NASA’s commercial crew program.
NASA officials say that the next round of contracts aims at building a human rated flight vehicle to dock at the ISS by late 2017.
The next contract phase known as Commercial Crew Transportation Capability (CCtCap) will result in one or more awards by NASA later this summer around August or September .
Sen. Nelson expressed his hope that the competition will continue since Congress appears likely to finally approve something near the President’s CCP funding request of over $800 million in the Fiscal 2015 NASA budget.
“With about $800 million, that’s enough money for NASA to do the competition for at least two and maybe more,” said Nelson. “That of course is up to NASA as they evaluate all the proposals.”
NASA had hoped to fly the first commercial crew missions in mid-2015.
But repeated CCP funding cuts by Congress since its inception in 2010 has already caused significant delays to the start of the space taxi missions for all three companies contending for NASA’s commercial crew contracts.
In fact the schedule has slipped already 18 months to the right compared to NASA’s initial plans thus forcing the agency to buy more Soyuz seats from the Russians at a cost of over $70 million each.
The reusable capsule will launch atop a man rated United Launch Alliance (ULA) Atlas V rocket.
It was glorious to be seated inside America’s next spaceship destined to carry humans.
The next generation of US human spaceflight is finally coming to fruition after a long down time.

KENNEDY SPACE CENTER, FL- Engineers have begun stacking operations for NASA’s maiden Orion deep space test capsule at the Kennedy Space Center (KSC) achieving a major milestone leading to its first blastoff from the Florida Space Coast less than six months from today.
The excitement is mounting as final assembly of NASA’s Orion crew vehicle into its launch configuration started on Monday, June 9, inside the Operations and Checkout (O&C) Facility at Kennedy.
Orion will eventually carry humans to destinations far beyond low Earth orbit on new voyages of scientific discovery in our solar system.
“Orion is the next step in our journey of exploration,” said NASA Associate Administrator Robert Lightfoot at a recent KSC media briefing.
“This mission is a stepping stone on NASA’s journey to Mars. The EFT-1 mission is so important to NASA.”
The main elements of the Orion spacecraft stack include the crew module (CM), service module (SM) and the launch abort system (LAS).
On Monday, technicians from Orion’s prime contractor Lockheed Martin began aligning and stacking the crew module on top of the already completed service module in the Final Assembly and System Testing (FAST) Cell in the O & C facility at KSC.
“Ballast weights were added to ensure that the crew module’s center of gravity can achieve the appropriate entry and descent performance and also ensure that the vehicle lands in the correct orientation to reduce structural impact loads,” according to Lockheed Martin.
Engineers will remain busy throughout this week continuing to work at a 24/7 pace to get Orion ready for the December liftoff.
The next steps involve completing the power and fluid umbilical connections between the CM and SM and firmly bolting the two modules together inside the FAST cell.
An exhaustive series of electrical, avionic and radio frequency tests will follow. The team will then conduct final systems checks to confirm readiness for flight.
The LAS will then be stacked on top. The entire stack will then be rolled out to the launch pad for integration with the Delta IV Heavy rocket.
The CM/SM stacking operation was able to move forward following the successful attachment of the world’s largest heat shield onto the bottom of the CM in late May. Read my prior story – here.
“Now that we’re getting so close to launch, the spacecraft completion work is visible every day,” said Mark Geyer, NASA’s Orion Program manager in a statement.
“Orion’s flight test will provide us with important data that will help us test out systems and further refine the design so we can safely send humans far into the solar system to uncover new scientific discoveries on future missions.”
Orion is NASA’s next generation human rated vehicle now under development to replace the now retired space shuttle. The state-of-the-art spacecraft will carry America’s astronauts on voyages venturing farther into deep space than ever before – past the Moon to Asteroids, Mars and Beyond!
No humans have flown beyond low Earth orbit in more than four decades since Apollo 17, NASA’s final moon landing mission launched in December 1972.
The two-orbit, four- hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.
One of the primary goals of NASA’s eagerly anticipated Orion EFT-1 uncrewed test flight is to test the efficacy of the heat shield in protecting the vehicle – and future human astronauts – from excruciating temperatures reaching 4000 degrees Fahrenheit (2200 C) during scorching re-entry heating.
At the conclusion of the EFT-1 flight, the detached Orion capsule plunges back and re-enters the Earth’s atmosphere at 20,000 MPH (32,000 kilometers per hour).
“That’s about 80% of the reentry speed experienced by the Apollo capsule after returning from the Apollo moon landing missions,” Scott Wilson, NASA’s Orion Manager of Production Operations at KSC, told me during an interview at KSC.
A trio of parachutes will then unfurl to slow Orion down for a splashdown in the Pacific Ocean.
The EFT-1 mission will provide engineers with critical data about Orion’s heat shield, flight systems and capabilities to validate designs of the spacecraft, inform design decisions, validate existing computer models and guide new approaches to space systems development. All these measurements will aid in reducing the risks and costs of subsequent Orion flights before it begins carrying humans to new destinations in the solar system.
“We will test the heat shield, the separation of the fairing and exercise over 50% of the eventual software and electronic systems inside the Orion spacecraft. We will also test the recovery systems coming back into the Pacific Ocean,” said Lightfoot.
“Orion EFT-1 is really exciting as the first step on the path of humans to Mars,” said Lightfoot. “It’s a stepping stone to get to Mars.”
“We will test the capsule with a reentry velocity of about 85% of what to expect on returning [astronauts] from Mars.”
Concurrently, new American-made private crewed spaceships are under development by SpaceX, Boeing and Sierra Nevada – with funding from NASA’s Commercial Crew Program (CCP) – to restore US capability to ferry US astronauts to the International Space Station (ISS) and back to Earth by late 2017.

KENNEDY SPACE CENTER, FL – Boeing expects to begin “assembly operations of our commercial CST-100 manned capsule soon at the Kennedy Space Center,” Chris Ferguson, commander of NASA’s final shuttle flight and now director of Boeing’s Crew and Mission Operations told Universe Today in an exclusive one-on-one interview about Boeing’s space efforts. In part 1, Ferguson described the maiden orbital test flights to the ISS set for 2017 – here.
In part 2, we focus our discussion on Boeings’ strategy for building and launching the CST-100 ‘space taxi’ as a truly commercial space endeavor.
To begin I asked; Where will Boeing build the CST-100?
“The CST-100 will be manufactured at the Kennedy Space Center (KSC) in Florida inside a former shuttle hanger known as Orbiter Processing Facility 3, or OPF-3, which is now [transformed into] a Boeing processing facility,” Ferguson told me. “Over 300 people will be employed.”
During the shuttle era, all three of NASA’s Orbiter Processing Facilities (OPFs) were a constant beehive of activity for thousands of shuttle workers busily refurbishing the majestic orbiters for their next missions to space. But following Ferguson’s final flight on the STS-135 mission to the ISS in 2011, NASA sought new uses for the now dormant facilities.
So Boeing signed a lease for OPF-3 with Space Florida, a state agency that spent some $20 million modernizing the approximately 64,000 square foot hanger for manufacturing by ripping out all the no longer needed shuttle era scaffolding, hardware and equipment previously used to process the orbiters between orbital missions.
Boeing takes over the OPF-3 lease in late June 2014 following an official handover ceremony from Space Florida. Assembly begins soon thereafter.
“The pieces are coming one by one from all over the country,” Ferguson explained. “Parts from our vendors are already starting to show up for our test article.
“Assembly of the test article in Florida starts soon.”
The CST-100 is being designed at Boeing’s Houston Product Support Center in Texas.
It is a reusable capsule comprised of a crew and service module that can carry a mix of cargo and up to seven crew members to the International Space Station (ISS) and must meet stringent safety and reliability standards.
How will the pressure vessel be manufactured? Will it involve friction stir welding as is the case for NASA’s Orion deep space manned capsule?
“There are no welds,” he informed.
“The pressure vessel is coming from Spincraft, an aerospace manufacturing company in Massachusetts.”
Spincraft has extensive space vehicle experience building tanks and assorted critical components for the shuttle and other rockets.
“The capsule is produced by Spincraft using a weld-free process. It’s made as a single piece by a proprietary spun form process and machined out from a big piece of metal.”
The capsule measures approximately 4.56 meters (175 inches) in diameter.
“The service module will be fabricated in Florida.”
The combined crew and service modules are about 5.03 meters (16.5 feet) in length.
“In two years in 2016, our CST-100 will look like the Orion EFT-1 capsule does now at KSC, nearly complete [and ready for the maiden test flight]. Orion is really coming along,” Ferguson beamed while contemplating a bright future for US manned spaceflight.
He is saddened that it’s been over 1000 days since his crew’s landing inside shuttle Atlantis in July 2011.
With Boeing’s long history in aircraft and aerospace manufacturing, the CST-100 is being designed and built as a truly commercial endeavor.
Therefore the spacecraft team is able to reach across Boeing’s different divisions and diverse engineering spectrum and draw on a vast wealth of in-house expertise, potentially giving them a leg up on commercial crew competitors like SpaceX and Sierra Nevada Corp.
Nevertheless, designing and building a completely new manned spaceship is a daunting task for anyone. And no country or company has done it in decades.
How hard has this effort been to create the CST-100? – And do it with very slim funding from NASA and Boeing.
“Well any preconceived notion I had on building a human rated spacecraft has been completely erased. This is really hard work to build a human rated spacecraft!” Ferguson emphasized.
“And the budget is very small – without a lucrative government contract as used in the past to build these kind of spacecraft.”
“Our budget now is an order of magnitude less than to build the shuttle – which was about $35 to $42 Billion in 2011 dollars. The budget is a lot less now.”
Read more about the travails of NASA’s commercial crew funding situation in Part 1.
The team size now is just a fraction of what it was for past US crewed spaceships.
“So to support this we have a pretty small team.”
“The CST-100 team of a couple hundred folks works very hard!”
“For comparison, the space shuttle had 30,000 people working on it at the peak. By early 2011 there were 11,000. We flew on STS-135 with only 4,000 people in July 2011.”
Boeing’s design philosophy is straightforward; “It’s a simple ride up to and back from space,” Ferguson emphasized to me.
Next we turned to the venerable Atlas V rocket that will launch Boeing’s proposed space taxi. But before it can launch people it must first be human rated, certified as safe and outfitted with an Emergency Detection System (EDS) to save astronauts lives in a split second in case of a sudden and catastrophic in-flight anomaly.
United Launch Alliance (ULA) builds the two stage Atlas V and is responsible for human rating the vehicle which has a virtually unblemished launch record of boosting a wide array of advanced US military satellites and NASA’s precious one-of-a-kind robotic science explorers like Curiosity, JUNO, MAVEN and MMS on far flung interplanetary voyages of discovery.
What modifications are required to man rate the Atlas V to launch humans on Boeing’s CST-100?
“We will launch on an Atlas V that’s being retrofitted to meet NASA’s NPR human rating standards for redundancy and the required levels of fault tolerance,” Ferguson explained.
“So the rocket will have all the safety NASA wants when it flies humans.”
“Now with the CST-100 you can do all that in a smaller package [compared to shuttle].”
“The Atlas V will also be modified by ULA to include an Emergency Detection System (EDS). It’s a system not unlike what Apollo and Gemini had, which was much more rudimentary but quite evolved for its day.”
“Their EDS would monitor critical parameters like pitch, roll, yaw rates, critical engine parameters. It measures the time to criticality. You know the time to criticality for certain failures is so short that they didn’t think humans could react to it in time. So it was essentially automated.”
“So if it [EDS] sensed large pitch or yaw excursions, it would self jettison. And the escape system would kick in automatically.”
The Atlas V is already highly reliable. The EDS is one of the few systems that had to be added for human flights?
“Yes.”
“We also wanted a better abort system performance to go with the two engine Centaur upper stage we elected to use instead of the single engine Centaur.”
The purpose is to shut down the Centaur engine firing [in an emergency].”
“The two engine Centaur has flown many times. But it has never flown on an Atlas V. So there is a little bit of recertification and qualification to be done by ULA to go along with that also.”
Does that require a lot of work?
“ULA doesn’t seem to think the work to be done is all that significant. There is some work to be done.”
So it’s not a showstopper. Can ULA meet your 2017 launch schedule?
“Yes.”
“Before an engine fails it vibrates. So when you talk about automated ‘Red Lines’ you have to be careful that first you “Do No Harm” – and not make the situation even worse.”
“So we’ll see how ULA does building this,” Ferguson stated.
The future of the CST-100 project hinges on whether NASA awards Boeing a contract to continue development and assembly work in the next round of funding (dubbed CCtCAP) from the agency’s Commercial Crew Program (CCP). The CCP seed money fosters development of a safe, reliable and new US commercial human spaceship to low Earth orbit as a public/private partnership.
NASA’s announcement of the CCP contract winners is expected around late summer 2014.
Based on my discussions with NASA officials, it seems likely that the agency could select at least two winners to move on – to spur competition and thereby innovation – from among the trio of American aerospace firms competing.
Besides Boeing’s CST-100, the SpaceXDragon and Sierra Nevada Dream Chaser vehicles are also in the running for the contract to restore America’s capability to fly humans to Earth orbit and the International Space Station (ISS) by 2017.
In Part 3 we’ll discuss with Chris Ferguson the requirements for how many and who will fly aboard the CST-100 and much more. Be sure to read Part 1 here.
Stay tuned here for Ken’s continuing Boeing, SpaceX, Orbital Sciences, commercial space, Orion, Curiosity, Mars rover, MAVEN, MOM and more planetary and human spaceflight news.
Talk about a high-flying career! Being a government astronaut means you have the chance to go into space and take part in some neat projects — such as going on spacewalks, moving robotic arms and doing science that researches the nature of the human body.
Behind the glamor and the giddiness of flight, however, astronauts also need to pay their bills on Earth. How much you get paid as an astronaut depends on what agency you work for – as well as your experience, just like any other career.
The information below for NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA) is current as of April 2014, unless otherwise noted. Three agencies do not disclose salary scales online, at least in English pages: the Japan Aerospace Exploration Agency (JAXA), the Russian Federal Space Agency (Roscosmos) and the China National Space Administration (CNSA).
NASA
NASA has 43 active astronauts and eight astronauts-in-training who were selected in 2013. Until basic training is completed, which takes about two years, selectees are called “astronaut candidates”. (Astronauts from other agencies, such as ESA and CSA, often join NASA selectees for basic training.) Then even after they’re selected, it could be years more before they take a spaceflight.
Some astronauts are hired as civilian employees while others come over from the military. Civilian astronauts are paid according to a government scale that ranges from classifications GS-11 to GS-14.
In 2012, employees living in Houston (where astronaut training facilities are located) make a minimum of $64,724 for a GS-11 to a maximum of $141,715 for a GS-14. As employees pick up more qualifications, responsibility and experience, their salaries increase.
Military salaries were not disclosed, but NASA said those employees from the armed forces “remain in an active duty status for pay, benefits, leave, and other similar military matters.”
European Space Agency
ESA’s most recent astronaut class was selected in 2009. They have all either flown in space, or have been assigned to future missions aboard the International Space Station. Astronauts are paid between the A2 and A4 scales set by the Coordinated Organisations, a group of European intergovernmental groups.
“Upon entering the ESA Astronaut Corps, new recruits will generally be paid at the A2 level. Following the successful completion of the basic astronaut training, the recruit will be paid in accordance with the grade A3. The promotion to the grade A4 generally follows after the first spaceflight,” the European Space Agency stated.
While ESA’s website does not specify the salaries for astronauts beyond the grade, another Coordinated Organisation – called the North Atlantic Treaty Organisation – lists the annual A2 salary as 58,848 Euros ($81,404) and the A4 salary as 84,372 Euros ($116,619.)
Canadian Space Agency
Canada has two active astronauts, neither of which have been assigned to a spaceflight yet. The CSA does not disclose on its website how much astronauts make, but some information is available on the website of the Privy Council Office – an advisory group to Canada’s prime minister and senior officials.
As of 2011, astronauts are paid a minimum of $89,100 Canadian ($80,897) in Grade 1 and a maximum of $174,000 Canadian ($158,470) in Grade 3. Newly minted astronaut candidates appear to move to Level 2 upon completing basic astronaut training, which takes two years, and then increase their salary with more experience.
Military astronauts are paid according to a separate scale that was not disclosed in PCO documents.
Becoming a government astronaut
Generally, you must be the citizen of a particular country with a space program to apply as an astronaut. U.S. astronauts are U.S. citizens, European astronauts are citizens of European countries, and so forth.
Each space agency has periodic astronaut selections where they put out a call for candidates and then winnow down the list to a handful of people selected for astronaut training. The United States had its last selection in 2013, and ESA, CSA and JAXA did theirs in 2009.
While space agencies are careful not to specify certain kinds of degrees or universities for applicants, generally speaking astronauts have technical, medical or military backgrounds.
Astronauts are best known by the public for their time in space, but in reality they will spend most of their careers on the ground. International Space Station astronauts are expected to be proficient in station systems, science and spacewalks. They also must learn how to operate the Soyuz spacecraft that gets them into space, and to learn Russian since that country is a major partner of the International Space Station.
When astronauts aren’t training, they’re working to support other missions — sometimes in locations such as NASA’s Mission Control or in pools used for spacewalk training. They additionally spend hours of time doing outreach for schools and other audiences, and travelling all over the world to the various training centers used to get people ready for spaceflight.
It’s a tough career, but those who make the trek into space say the view is totally worth it.

“Talk about a selfie!” wrote former astronaut Clay Anderson on Twitter yesterday (Oct. 1). He posted that comment along with a favorite photo from Expedition 15, when he was standing in restraints on the robotic Canadarm2. Off in the distance, he saw his shadow against the solar array panels of a Soyuz spacecraft.
That got us thinking — what are the best astronaut selfies? Below are some of our favourites (some intentional, some not) from over the years. Any that we have missed? Let us know in the comments!
