Journey of an Astronaut – Dr Rosemary Coogan

Dr Rosemary Coogan is the UK’s Astronaut, trained to visit the International Space Space and undertake work there for 6 months on behalf of the UK Space Agency. As commercial space stations are built and the Artemis Moon programme develops, the possibilities for further space trips for Rose are growing.

We are recording her journey here so you can follow – maybe not just Rose’s story, but perhaps you could follow in her footsteps with your career?

Bath Astronomers have been supplying life-sized cut-outs of Rose to local schools to inspire young minds.

It takes about 45 minutes to get all her gear on before a helmet is carefully lowered over her head. The British astronaut is about to undergo her toughest challenge yet – assessing whether she is ready for a spacewalk. The test will take place in one of the largest pools in the world: Nasa’s Neutral Buoyancy Laboratory at the Johnson Space Center in Houston, Texas. The pool – which is 12m deep (40ft) – contains a life-sized replica of the International Space Station (ISS), and a “spacewalk” here is as close as it gets to mimicking weightlessness on Earth.

EVA Exams – underwater

Rosemary Coogan is surrounded by a team of people pushing, pulling, squishing and squeezing her into a spacesuit.

“It’s a big day,” Rosemary says before the dive, which is going to last more than six hours. “It’s very physically intense – and it’s very psychologically intense.”

Rosemary was interviewed by BBC for Instagram post and video available below.

A little bit of “In Suit Light Exercise” to get ready for a spacewalk! As part of our training, we had a full dress rehearsal of a typical spacewalk day, including exercising in the suit to purge Nitrogen from the body and decrease the risk of decompression sickness. Mission Control guides the crew through 50 minutes of this activity – what a great team warm-up!

Ever wondered how astronauts prepare for the weightlessness of space? In Bordeaux, France, our astronauts train for microgravity using parabolic flights! These special flights create brief periods of zero gravity, mimicking the conditions of space. By performing a series of steep climbs and descents, the plane allows astronauts to experience intense 2G forces before entering a 22-second weightless phase! This crucial training helps future astronauts adapt to moving, working, and even jumping in zero gravity. Join us as we follow Rosemary Coogan, Sławosz Uznański-Wiśniewski, and John McFall on their parabolic flight training.

Getting the right suit fit for an EVA is a delicate art! There are different sizes of upper torso, brief assembly, legs, arms and gloves, as well as extra sizing rings you can put between components. My first suit fit check went through all the basics – how to do the “runner’s stretch” into the legs, checking I could reach all the switches, valves and visors on the suit, and even just how to get in to the upper torso (this took me a few attempts the first time)! I’ve just had my second fit check, tweaking and fine-tuning, now that I’ve had the chance to train in the suit. A huge thank you to the incredibly patient suit technicians and engineers, as well as Nicole and @astro_luca for sharing their experiences

Even though we don’t feel the effects of gravity on the ISS – it doesn’t mean moving around massive objects is always easy! We discovered this in the VR lab, installing very large pieces of hardware on the outside of the ISS. The robotic system in the lab mirrors the lack of weight (as you’d have in microgravity), but the simulated boxes still have a huge amount of inertia when they get moving! We had to keep a controlled grip, only making very small and careful movements to get them aligned in the right places

My first taste of space food!🍴 During our food preparation lesson we had the chance to make some food and drink from the ISS menu, using the galley rack Potable Water Dispenser. I went for an Earth favourite of vegetarian chilli and lemonade, and it was great!

Back in the pool for the next EVA run! 👩‍🚀 For our third session we were training for the swapout of hardware outside the ISS, taking spares and tools with us from the airlock, translating to the worksite, and then removing and replacing a failed component. I was also lucky enough to have @raphael_astro as one of my “suit IVs” for the morning – an important role also in space, helping astronauts going on a spacewalk to correctly don their suits, tethers, and tools. I’ll be practising this myself later this week!

Spacewalk training

Dr Rosemary Coogan – Northern Ireland’s first ever astronaut – has said the space sector is “very much changing in terms of having more and more commercial partners”.

The astrophysicist, who was speaking to BBC News NI, is currently in the US for pre-assignment training and is undergoing rigorous spacewalk training.

Today is International Day of Women and Girls in Science! As an astronaut and astrophysicist, I’m so grateful to all the people who paved the way for the incredible missions we’re working on today. To all the young people dreaming of the stars: keep questioning and keep exploring!

Glove Fitting

One of the most important parts of a spacesuit is the gloves! To estimate the right sizes of suit components, 3D scans are made of the entire body, with separate detailed scans of the hands.

EVA Training at NASA in Houston

This was a special moment for Rosemary – going underwater in the spacesuit for the first time, to train for a spacewalk (an “EVA”) 👩‍🚀

Rosemary arrived at NASA in Houston, where she’ll be staying for 6 months to learn how to do an EVA outside the International Space Station (ISS). She’ll also be trained on the workings of the spacesuit itself, how it keeps astronauts safe in the vacuum of space, and learning about the many different systems onboard the ISS.

A day in the life

What’s it like to train as an astronaut?

Rosemary showed us how she’s preparing for space with a parabolic flight.

Testing Moon camera

ESA astronaut Rosemary Coogan points at a lunar-like landscape with a camera designed to take pictures on the surface of the Moon during the Artemis missions.

Rosemary had the chance to handle the camera during an imagery meeting with NASA in Europe in 2023. Now, she has tested the camera’s performance in realistic scenarios for geological exploration.

“This training is teaching us how to take the right samples, make the right descriptions, and take the right photos, so the scientists have everything they need,” she says.

Pangaea Training

It was an eye-opening first week of PANGAEA training for Rosemary with @arnaud_astro, Norishige “Nemo” Kanai and the European Space Agency PANGAEA team! They’ve learned which geological features are important to identify and how to report them – which is especially important for future exploration missions to the Moon and beyond, where astronauts will act as the eyes of the specialists on ground. The highlights so far:

* learning how to read the story of the Dolomites over millions of years, through its rocks and outcrops (showing whether there used to be volcanic activity, rivers, lakes etc)

* finding ancient fossils of extinct reptiles in the Bletterbach canyon, and

* studying a wonderful meteorite collection brought by the experts – including some incredible Lunar and Martian samples!

First Hoppers assigned ISS mission

ESA astronauts Sophie Adenot and Raphaël Liégeois have been assigned for their first spaceflights to the International Space Station (ISS) on missions currently planned for 2026.

April 22, 2024

The Hoppers become Astronauts

Rosemary Coogan graduated together with her fellow ESA astronaut candidates Sophie Adenot, Pablo Álvarez Fernández, Raphaël Liégeois and Marco Sieber and received astronaut certification at ESA’s European Astronaut Centre. This officially marked their transition into fully-fledged astronauts, ready and eligible for spaceflight.
The class of 6 astronauts were dubbed the Hoppers because of their constant hopping between buildings during training.
