Japanese Cargo Vessel Arrives at International Space Station

The Japan Aerospace Exploration Agency's H-II Transfer Vehicle(HTV), or "Kounotori" has arrived at the International Space Station on its fifth mission to resupply the orbiting complex.

Carrying 5.5 tonnes of cargo for the crew aboard the orbiting laboratory, HTV-5 lifted off from the Tanegashima Space Center in southern Japan under clear skies aboard a H-IIB rocket at 11:50 a.m. UTC on Wednesday, August 19 bound for a five day trip to the station.

On Monday August 24 the HTV performed a rendezvous with the International Space Station before being grappled by the station's 57 foot long robotic arm, Canadarm2. Assisted by Kjell Lindgren of NASA, Japanese astronaut Kimiya Yui was at the controls of Canadarm2 from the robotics workstation in the Cupola. He was given the "Go for grapple" command by fellow Japanese astronaut Koichi Wakata who was serving as CAPCOM(The voice link between astronauts on the ISS and Mission Control on Earth) during the on-orbit operations in Mission Control in Houston.

Yui then handed over control of the robot arm to teams back on Earth who issued a series of commands to Canadarm2 to slowly berth HTV-5 to the Earth-facing port of the Harmony Module of the ISS.

Included in the launch manifest is a space radiation observatory to search for dark matter, which will be installed on the exposed facility of the Japanese Experiment Module, pumps and filters for the station's Water Recovery System as well as food, water and other crew commodities for the astronauts and cosmonauts serving as part of Expedition 44.

HTV-5 is expected to remain docked to the station until late September before being loaded up with trash and other unwanted items and detached- destined for a fiery demise by burning up in the Earth's atmosphere.

Meanwhile back on Earth in Baikonur, Kazakhstan the crew of the Soyuz TMA-18M are undergoing final preparations and tests before launching to the station on September 2. Soyuz commander Sergei Volkov, making his third flight to the station will be flanked by rookie astronauts Andreas Mogensen of the European Space Agency and Kazakh cosmonaut Aidyn Aimbetov.

Volkov is scheduled to remain on board the station for the next several months as part of Expedition 45/46 while Mogensen and Aimbetov will be busy conducting scientific experiments during a short 10 day "Taxi mission" to the orbiting complex. This will allow crews to effectively swap out Soyuz vehicles, with Mogensen and Aimbetov returning to Earth on the Soyuz TMA-16M with veteran cosmonaut Gennady Padalka, who will come home after spending 170 days living and working in space.

ISS One Year Crew members Scott Kelly and Mikhail Kornienko will return to Earth aboard the Soyuz TMA-18M with Volkov in March 2016.

NASA's Orion Spacecraft Completes First Test Flight

NASA's next generation crew vehicle Orion, designed to take astronauts to deep space destinations such as the Moon, an asteroid and Mars, has completed its first test flight around the Earth.

Atop a Delta IV Heavy rocket, Orion lifted off from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida at 12:05 p.m. GMT. This uncrewed mission, designated Evaluation Flight Test-1(EFT-1) tested systems critical to future crew safety, also marks the first time that a spacecraft designed to carry humans has gone beyond the bounds of low-Earth orbit and into deep space since the days of Apollo.


Less than eighteen minutes of powered flight, Orion reached its initial orbit. After completing one revolution around the Earth, the second stage of the Delta IV fired its engines once again for a 4-minute, 45-second engine burn to raise Orion to a higher orbit, now 5,800 kilometers above the Earth(15 times higher than the orbit of the International Space Station).

Passing through the Van Allen Radiation Belts, data recorders on board measured the radiation levels being received by the spacecraft in order to analyse the doses of radiation astronauts would receive on future missions on Orion to deep space. Two cameras on board were also in a position to capture images of Earth from 5,800 kilometres above the planet.

Trial by Fire
Nearly three and a half hours after launch, Orion separated from its Service Module and the Delta IV Heavy, then fired its thrusters to set it on course for a fiery re-entry through the Earth's atmosphere. Traveling at around 32.000kmh during re-entry, Orion's heat shield experienced temperatures of 4000 Degrees Celsius, 80% of the temperature that would be experienced on a return journey from the Moon, as it made its journey home.

During this time there was an expected 2.5 minute loss of communications(LOS) between Orion and Mission Control teams in Houston, who were led today by Flight Director Mike Sarafin, as superheated plasma formed around the vehicle itself, blocking signals both in and out.

Finally, over 4.5 hours after launch in Florida, with its three parachutes fully deployed, Orion, now traveling at less than 30kmh, Orion splashed down in the Pacific Ocean, around 270 miles off the coast of Baja, California at 4:29 p.m.

NASA Administrator Charlie Bolden later said in a statement:
“Today’s flight test of Orion is a huge step for NASA and a really critical part of our work to pioneer deep space on our Journey to Mars.. The teams did a tremendous job putting Orion through its paces in the real environment it will endure as we push the boundary of human exploration in the coming years.”

Recovery
Members of the US Navy aboard the USS Anchorage were in the vicinity of the landing zone to recover the Orion spacecraft. Once the vehicle was made safe, cables were attached by divers and Orion was towed into the flooded deck of the ship. Once secure, the vessel began the journey home to port in San Diego.

What Happens Next?
Once data from today's flight has been analysed the focus for the NASA teams working on Orion systems will turn to the next flight of Orion. Mission EM-1 will involve another test flight of the Orion Crew Module, this time attached to a Service Module designed by the European Space Agency. This mission will fly beyond the Moon in 2017. The first crewed flight of Orion to the Moon is expected for 2021.

Orion will be used to carry astronauts to an asteroid that will be placed in a stable lunar orbit in the 2020s as part of the Asteroid Redirect Mission. Designed to carry four people to deep space, Orion will facilitate the exploration of other bodies in our solar system for the first time in over forty years.

On a sidenote..
Orion was originally scheduled to lift off from the Cape at 12:05 p.m. GMT on Thursday December 4, but a fault in one of the Delta IV's valves meant launch had could not take place inside the specified launch window, resulting in the scrubbing of the launch by 24-hours.

Also, legendary former NASA Flight Director Gene Kranz, who led teams in Mission Control on numerous Apollo flights to the Moon, was a special VIP guest in the Mission Control Center in Houston this week. Kranz was one of the Flight Directors on Apollo 17, a mission which marked the last time humans have traveled to and returned from deep space.

The Challenges of a One-Year Mission to Space



On Friday March 27 2015, astronaut Scott Kelly and cosmonaut Mikhail Kornienko launched atop a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan, marking the beginning of a year-long mission to the International Space Station.

Kelly and Kornienko, known as the "One Year Crew" launched from the Baikonur Cosmodrome in Kazakhstan along with cosmonaut Gennady Padalka at 19:42 GMT on Friday. The pair will live aboard the orbiting complex for one year, before returning to Earth in March 2016.

The one year mission will allow scientists to see how the human body will adapt to the microgravity living and working conditions found aboard the ISS, as well as examining the psychological effects of living off the planet for one year.  The scientific community will also be carefully watching how Kelly and Kornienko re-adapt to life back on Earth after spending a year in low-Earth orbit.

Changes in vision are just one of the many side effects that have been observed in some astronauts returning from long-duration spaceflights, and researchers want to learn more about its root causes and develop countermeasures to minimize this risk.

The duo will also have to combat bone and muscle loss (which happens to every astronaut when they fly in space for several months) by exercising for 2.5 hours each day, using the station's treadmills, bike machine known as CEVIS(Cycle Ergometer with Vibration Isolation and Stabilization System) and a weights machine called ARED(Advanced Resistive Exercise Device). For a six month mission, astronauts can lose up to 15% muscle volume.

Just in case you were wondering, this will not be the first time human beings will be sent into orbit for a year-long mission. In 1994, cosmonaut Valeri Polyakov spent over 437 days living aboard the Russian space station Mir, before returning to Earth in 1995. Despite suffering from a clear decline in morale for the first two months of his mission, Polyakov was able to regain his pre-flight mood for the rest of his stay aboard the station.

Upon returning to Earth in his Soyuz capsule after a successful mission, Polyakov decided he would rather walk the small distance from his spacecraft to a nearby reclining chair, demonstrating that humans would be able to walk on the surface of Mars after several weightless months in transit from Earth. This extra-long duration mission showed that the human body could deal with the strains and stresses of living in space for such an extended period of time. However, Kelly and Kornienko will be the first space farers to spend a year living on the International Space Station.

Recently I began asking astronauts who have spent time living and working aboard the ISS about the one year mission, and what they thought the biggest challenges will be for Kelly and Kornienko.

ESA astronaut and Expedition 26/27 Flight Engineer Paolo Nespoli, who spent six months living on the ISS in 2010 & 2011, told me that now is a good time to an attempt a mission of this nature:

 "I feel we need to know more about what happens to the body and what happens to the mind when you stay in space for a long time, so I think that now is a good time and I think we should do it."

Nespoli went on to mention that the technology we have on the space station is far superior to what Polyakov had at his disposal on Mir, and how it will be easier to connect with family friends and Mission Control teams all over the world.

"There was a Russian cosmonaut(Polyakov) who stayed in space for well over a year, so the Russians have done this in a more restricted and confined environment than what is today space station, where we have internet, telephone, teleconference capabilities so we can talk to Mission Control whenever we want".

I also asked Doug Wheelock, who, like Nespoli, lived aboard the ISS alongside Scott Kelly, about his thoughts on the upcoming mission, and what challenges would be faced by the one year crew. He went on to say that the biggest obstacles would be dealing with the mental stresses of living off the planet for such a long time:

"I think the greatest challenge will be managing the physiology & psychology of isolation, emotion, & senses... it is critical to stay in the moment".

Finally, I recently spoke with Expedition 35/36 Flight Engineer Chris Cassidy, who returned from the International Space Station back in September 2013, about his thoughts on the one year mission:

"In my experience on coming home day, as we were closing the hatch I thought to myself "What would I think if I was halfway done right now? How would I feel? What would I need? To be honest I felt a little accumulative fatigue- when you're living at your workplace, and you can't shut the door to work and go home in the evening and kick back and watch Monday Night Football- you're there all the time and it eventually catches up to you".

Cassidy, who completed a total of three spacewalks, or EVAs, during his most recent flight, also had a few ideas regarding how the crew doesn't become fatigued with the heavy workload that comes with living aboard the orbiting outpost, suggesting a longer weekend from time to time in the second half of the mission:

"I think my recommendation would be in months 7 through 12, the second half of the year is to have a three day weekend every month because you really need a good recharge. Sunday is a really good day to have a recharge, and to have an extra Sunday thrown in the mix every now and then would go a long way".

All in all, it appears that everyone in science and space exploration fields are confident about the one year mission. Both Kelly and Kornienko have lived aboard the ISS before, so it's fair to say that we have a very experienced crew on our hands, logging a total of 356 days in space between them. In addition, their Soyuz Commander Gennady Padalka will become the first four-time commander of the space station, and upon returning to Earth at the end of Expedition 44 will have logged a total of nearly 900 days in space.

It is hoped that data recorded from this mission will assist teams on the ground in their understanding of the effects of long terms weightlessness on the body, and what it may be like for humans if they were sent on a mission to Mars in the future. After Kelly and Kornienko return to Earth in 2016, we will no doubt, be one small step closer to the human exploration of the Red Planet.

Godspeed Scott and Misha!

Apollo 13: A Story of Teamwork, Competence and Responsibility

(This post was originally published on April 10 2013 and has since been updated).
by Cian O'Regan

Forty-seven years ago this month, Apollo 13 launched into the skies above Cape Canaveral to begin its bold journey to the Moon's Fra Mauro Highlands. 

We've all seen the movie, and for most it's a very realistic and true reflection of what happened on that perilous voyage to our nearest neighbour. But just how did Jim Lovell, Fred Haise and Jack Swigert make it home all those years ago?

Today we will focus on three key human factors that ultimately contributed to bringing the astronauts home. Some of these factors come straight from the Foundations of Mission Control - a charter drawn up after the Apollo 1 fire to serve as a code of conduct for those supporting manned flights from the ground.

These rules which are still followed to this very day define the values, expectations and responsibilities that each and every employee in Mission Control was expected to understand, believe and live as a member of the NASA team.

Teamwork: "Respecting and utilising the ability of others, realising that we work toward a common goal, for success depends on the efforts of all".

Apollo 13 was more than just three astronauts fighting a crippled spacecraft a quarter of a million miles from home.

Lovell, who at the time was NASA's most experienced astronaut, alongside rookie spacefliers Haise and Swigert were just the tip of the iceberg of the manned US space programme. Below them stood thousands of hard working Americans ready to bring them home. No matter how important or high up you were, on or off the planet, you worked the problem together as a team.

Responsibility: "Realising that it cannot be shifted to others, for it belongs to each of us; we must answer for what we do, or fail to do".

Every single person involved in the Apollo 13 mission were responsible for the jobs they had to do, no matter how big or small. The CAPCOM(Capsule Communicator) was responsible for communicating with the crew in space. The Flight Director took responsibility for crew safety and mission success(crew safety being the number one priority).

Everyone had their own role that they had to take control of in order to bring the crew home. Without even the smallest of jobs being carried out, the crew might not have made it back alive.

Competence: "There being no substitute for total preparation and complete dedication, for space will not tolerate the careless or indifferent".

Mission Control Celebrates

Strong words right? But we can only assume by this statement that every single person involved in bringing the astronauts home must have been prepared to deal with any problem that arose.

No Apollo crew had ever trained for an explosion fifty-five hours into flight. Hence, some procedures being given to the crew had never been tried or even though of prior to the disaster. In the face of adversity, sometimes you have to put the flight plan to one side and deal with what's actually happening in front of you.

Keeping a cool head was essential, something that was perfectly summed up by Flight Director Gene Kranz moments after the explosion took place;

"Everybody keep cool, work the problem, let's not make things any worse by guessing."

No crazy decisions were made on the spur of the moment - every move was studied in detail before it was executed. We must remember that a lot of problems were being dealt with for the first time on Apollo 13, something that makes the crew's safe return so unique yet so extraordinary.

To finish, I leave you with my favourite line from the Foundations of Mission Control which can be applied in a lot more situations than flying and returning men from the Moon;

"To recognise that the greatest error is not to have tried and failed, but that in trying, we did not give it our best effort."
