Tim Peake is a British astronaut currently living and working on the International Space Station. He traveled to space aboard a Russian Soyuz spacecraft and now performs experiments and maintenance tasks to support the mission in space. Back on Earth, mission control centers in the US and Russia support the astronauts in space by monitoring the station and communicating with the crew. When his mission concludes, Tim will return to Earth on another Soyuz capsule, landing on the steppe of Kazakhstan.
This is Tim, Newton and Principia. What’s one got to do with the other??
The photo was taken at the Royal Society, at an event held to celebrate the naming of Tim’s mission. ESA gives names to all of astronaut’s missions. ESA asked the whole of Europe to suggest names for Tim’s mission, and there were more than 4000 suggestions.
Tim chose from all of these the name Principa, which was suggested 20 times, to honour the great British scientist. Newton was a strong choice, there were many other suggestions relate to Newton (Newton, Isaac, 1687 , Trinity etc) – it was a very strong theme, because of the clear resonances.
The Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687, first described gravity, which is of course the physics at the very heart of space flight.
Suggested questions:
Do you know who Isaac Newton is?
What is gravity?
Do you know how Newton came up with his theory? Apple…
Why is gravity an issue for spaceflight?
Tim is part of Europe’s team of space plumbers/lab techs/space walkers/robotic operators etc.
6 astronauts were selected in 2009 to join the existing team of astronauts (at ESA, NASA, Roscosmos)

Video of Soyuz rendezvous and docking (ESA): https://www.youtube.com/watch?v=M2_NeFbFcSw
The Soyuz will dock with the ISS 6 hours after launch
Tim will be living and working here for 6 months from 15 December 2015 – May 2016
What is the ISS?
ISS is an international orbiting laboratory in low earth orbit (about 400km up). Continuously occupied since 2000, home to an international crew.
Video of ISS orbiting, timelapse: http://www.esa.int/spaceinvideos/Videos/2014/12/Alexander_Gerst_s_Earth_timelapses
Minute: 1:52 goes past the UK
Suggested Questions:
Do you know how far away the ISS is from Earth? About 400km up
How fast do you think it’s flying? 7kilometers per second
How many astronauts do you think live here? Normally 6, when a new crew of 3 arrives, there are 9 astronauts for a period of around 2 weeks
How long does it take to go once round Earth? Every 90 minutes, 15.5 orbits per day
How does the ISS stay up / not pulled back to Earth by gravity? Orbital boosting can be performed by the station's two main engines on the Zvezda service module
Where is Columbus?
This is Columbus. It’s Europe’s main contribution to the ISS.
It was attached to the ISS on 11 February 2008
c. 7m Long
C 4.5m Diameter (max) (About the size of 1 double decker bus, spun on it’s axis)
Weigh c. 12 tonnes (about 1 fully laden bus)
Other interesting / fun facts here on Columbus?
Questions
What do you think is important when designing the lab? Protection from sun, radiation, debris
What do you think it needs to run? Power, water, life support
A fish eye view inside the module. As you can see, there are no windows (sadly, a design flaw, engineers have on occasion overlooked the importance of windows). The Cupola came close to being shelved, but the astronauts demanded it be flown. They love the views, and we get amazing photographs from it).
Columbus is crammed wall to wall (and ceiling) with Experiment racks. The systems equipment (computers, air conditioning, water cooling loops etc) are hidden in the floor (deck racks) and in the corners.

This is the EML – electromagnetic Levitator – it heats metal to very high temperatures (2000+°C!) so that it melts, and can be cooled again very quickly.
It is on the European Columbus module of the ISS.
The magnets holds the metal in place and stop it floating away.
In the absence of gravity, very precise measurements on properties of the metal can be made – especially as there is no container to hold the metal.
The information gained through looking at metals this way leads to new alloys with useful characteristics, e.g.
Lightweight
Stronger
Conductive
Pliable
UK scientists are contributing to 2 international experiments using this laboratory.
Previous experiments have led to breakthroughs, like 40-50% reduction in the weight of important parts for turbines – this saves energy and materials; which is good from a financial and an environmentaal point of view.
Two experiments, BOSS and BIOMEX, are mounted on the outside of the ISS.
This exposes microorganisms to the harsh conditions of space

Weightlessness increases pressure in upper body and head
Unique British hardware, developed by SME from Southampton, Marchbanks Measurement Systems, is being tested to measure the changes in brain pressure
Normally done by drilling into the skull or lumbar puncture!
New device is non-invasive – can indicate brain pressure just by placing in the ear
Critical for astronaut health – especially on longer duration missions

A new experiment called SUPVIS-M will see Tim Peake control a rover on Earth from orbit the ISS
The rover will be in a ‘Mars yard’ in Stevenage (at Airbus Defence and Space) – a mock-up of the Martian environment on Earth – in a simulation of how we may explore Mars in future
Makes the most of UK expertise in robotics and telecommunications
Science – Ground Operated Experiments
As well as the Human Physiology experiments, there are many more experiments that are being run remotely by teams of scientists on the ground.
This is ESA’s Fluid Science Laboratory (FSL), running the GEOFLOW experiment (http://www.esa.int/Our_Activities/Human_Spaceflight/Columbus/Geoflow_experiment_starts_the_flow_of_data_from_the_Fluid_Science_Laboratory)
Miniature Earth
The core of the Geoflow experiment can be seen as a representation of Earth (or other planet) in miniature. A viscous incompressible fluid (silicone oil) is held between two concentric spheres, which rotate about a common axis. A high voltage difference between the spheres creates a force field that plays the role of gravity and holding the inner sphere at a higher temperature to the outside sphere creates a temperature gradient from inside to outside as, for example, on Earth.
Understanding the flow of the silicone oil under different conditions will be of importance in such areas as flow in the atmosphere, the oceans, and the movement of Earth's mantle on a global scale, as well as other astrophysical and geophysical problems. Results from Geoflow will also be useful for making improvements in a variety of engineering applications, such as spherical gyroscopes and bearings, centrifugal pumps and high-performance heat exchangers.
Maintenance
As well as running all the science experiments, the crew have to maintain the ISS itself. There are no plumber or electricians or so on in space, and so the crew have to do all of this work too. If the toilet breaks, fixing it becomes the most important job for the day.
This is Italian ESA astronaut Luca Parmitano replacing one of the Water Pump Assemblies (WPAs) in Columbus. The WPA pumps the water around the shell of Columbus, providing cooling to the powered equipment and air conditioning of the air.
There is a list of top 10Q&A on the UK Space Agency Blog. But, if you only have time for one thing, watching this 8 minute video from Suni Williams, where she explains sleeping, personal hygiene, going to the toilet and the kitchen. You’ll be able to answer all the most common questions after you see this: https://www.youtube.com/watch?v=XkM_04Ch76E
How do astronauts sleep in space?
Astronauts cannot lie ‘down’ in a bed because of the weightlessness. They zip themselves into special sleeping bags that have holes for the arms, which are attached to the wall inside their crew quarters. (Which are the size of a broom cupboard). They end up in a ‘Zombie’ pose.
What do astronauts eat in space?
Most food is long lasting (over 2 years), but some fresh fruit and vegetables are included with each cargo delivery. Imagine going hiking and camping for 6 months without going near a supermarket, and you get an idea of the food. A lot of food is flown in a dehydrated state, and the astronauts add warm or cold water to it before eating it. Some food is tinned or thermostabilied in pouches, and others just flown in natural form (like nuts, dried fruit etc.)
How do astronauts go to the toilet in space?
A seat belt and foot restraints hold the astronaut on the seat, while high-speed air currents pull the waste into the respective receptacles. There is a small potty like receptacle for solid waste, and a hose for liquid waste. Solid waste is collected and put into one of the cargo ships for disposal and destruction during re-entry. Liquid waste is recycled into drinking water.
What do they do in their free time?
At the weekends they have to do the cleaning and vacuuming. Evenings and weekends are their free time to relax, call and email friends and family, watch TV, play instruments and enjoy the view!
Food and Drink
Just like us, the crew have to eat and drink on board ISS. Their working days are very similar to ours, - they sometime eat lunch together, they sometimes just grab a ‘sandwich’. The crew will often try to eat together at evenings and weekend, - food serves exactly the same purposes on ISS as it does here on Earth, it is just different to eat and drink in space.
Food
Food is all pre-prepared, - there are no ovens to cook things on ISS. Dehydrated food is rehydrated using hot and cold water, other food comes in its natural from (crackers, nuts etc). Some food (mostly meat and fish) is thermostablised (canned or bagged) and heated in a food warmer. (Essentially a small suitcase with two hot plates).
Note the scissor – very important!

What would you choose to take with you?
Exercise
In order to help slow the rate of muscle and bone deterioration, the crew must exercise for 2 hours every day. (1 hour cardio, 1 hour weights).

More detail in the ‘careers’ presentation – on all the support team, engineers, scientists etc
NASA support the overall running of the ISS
But for the Columbus module we have our Columbus Flight Control Team, who monitors the Columbus module 24/7, 365 days a year.
This is Libby Jackson – she was a Columbus Flight Director (COL-Flight), in charge of the Columbus Flight Control team, based in Oberpfaffenhofen (Munich, Germany). That’s quite hard to say so our call sign is Munich. ‘Munich, we’ve got a problem…’
She has an overview of everything, and is supported by the rest of the Flight Control Team
There is a team of 4 people all the time, looking after the systems and payloads, with the Flight Director in charge.
COL FLIGHT: In charge of Columbus operations, reports to the Houston Flight Director (in NASA’s Johnson Space Centre)
COMET: : Looks after all the planning in the flight control room.
STRATOS: Monitors and remotely operates all of the Columbus systems (Electrical systems, Cooling, Computers, Fire detection etc.)
During the day this increases to include:
Eurocom: crew interface
COSMO: stowage and mechanics, - basically in charge of knowing how to fix everything and where everything is kept
Plus engineers in back rooms and all the payload specialists in USOC (User Support Operations Centres)
Video link of Soyuz undocking, re-entry and landing: https://www.youtube.com/watch?v=-l7MM9yoxII
Home Time
After about 6 months in orbit, it is time to come back to Earth. The crew will spend part of their time in the last couple of weeks refreshing their training, packing, checking the Soyuz for leaks and generally readying themselves for the journey home.
Return To Earth
http://www.nasa.gov/mission_pages/station/structure/elements/soyuz/landing_timeline.html
https://www.nasa.gov/mission_pages/station/structure/elements/soyuz/landing.html
It takes about 3 and a half hours from leaving the space station to landing back on Earth, though the hatches are closed a couple of hours before the crew leave, to allow for final leak checks and preparations.
Landing
The crew land back on the Kazakhstan Steppe. Parachutes slow the capsule a descent rate of about 7 metres per second, but this is still too fast for a comfortable landing. One second before touchdown, two sets of three small engines on the bottom of the vehicle fire, slowing the vehicle to soften the landing.
Crew report that the feelings is ‘like being in a controlled car crash’
Home!
You’ve survived re-entry, your capsule has hit the ground. Your body is feeling the effect of gravity after 6 months in a weightless environment. You may well be feeling queasy, battered, some crew even pass out. But you have to put a smile on your face and face the media. You’ll still be very happy to be home and smell fresh air though!
ESA astronaut Timothy Peake during a water survival training session near Star City, Russia, on 2 July 2014.
Survival training is an important part of all Soyuz mission training. When a Soyuz spacecraft returns to Earth there is always the possibility that it could land in water.
Tim is currently training for his long-duration mission to the International Space Station, to be launched at the end of November 2015. He will be the first British ESA astronaut to visit the Space Station. Until his assignment was announced in 2013, Tim was Lead Eurocom for Luca Parmitano’s six-month Volare mission that started in May of that year.
Tim will fly on 15 December 2015, first union jack in orbit for over 20 years.
