Living in Space

by Joan Marie Galat

Astronauts have been living over our heads—in outer space—on a continuous basis since 2000. It takes three astronauts to run the International Space Station (ISS) but up to ten may be on board at one time. The entire structure is as big as a football field but the living area is only about the size of a five-bedroom house. Giant solar panels power the station. Some of the electricity is used to split water into gas to generate oxygen for the astronauts. The ISS orbits the Earth at a speed of 28,500 kilometres per hour. That’s eight kilometres a second—25 times faster than the speed of sound! 

I wanted to know what it’s like to live on the ISS, and made plans to write a book on the topic. As part of my research, I visited NASA facilities and watched a SpaceX Falcon heavy rocket launch. The result is the middle grade novel Mortimer: Rat Race to Space (DCB 2022). Written for ages 9-12, it tells the story of a journal-keeping lab rat who sets out to collect scientific evidence that will prove his species is the one that should colonize Mars. Mortimer records video for his future YouTube channel, but not everything goes as planned. He is forced to face new truths about dreams, friendships, and choosing the right thing to do. You can read an excerpt on Amazon.ca or Amazon.com


I collected much more information than I could use, including these facts: 

- Astronauts can’t be too tall or short. If you want to be an astronaut, try to grow taller than 62 inches but stay below 75 inches. 

- American astronauts must have 20/20 vision, even if that means wearing glasses, contacts, or undergoing eye surgery. 

- In the USA, jet pilots with at least 1000 hours of flying time, and teachers who have taught K-12, can apply to be astronauts. 

- Astronauts practice everything they’ll do in space on Earth. This includes how to fix malfunctioning equipment, use cameras, conduct experiments, make a meal, stow equipment, and even store trash. 

- Every astronaut has a university education and experience in engineering, biological science, physical science, or math. 

- Astronauts find out what it’s like to be weightless before they go into space. They practice floating inside a high flying plane known as the vomit comet. The plane flies to an altitude of 24,000 feet then climbs at a 45 degree angle to reach 34,000 feet. It then enters a controlled free fall which involves traveling to 24,000 feet in a gradual curve, following a 30-degree descent. This gives about 20 seconds of being weightless. The sensation of weightlessness makes a lot of people feel nauseous. Passengers in the vomit comet also feel 1.8 times heavier when the plane reaches its lowest point. 

- You can experience a few seconds of being weightless when you go down a sudden drop on a rollercoaster or other amusement park ride. 

If you’d like to see the International Space Station pass by at night, visit the Resources page of my website to access information on alerts for your area. If you’re an educator interested in a STEM or STEAM-themed presentation based on Mortimer: Rat Race to Spacecontact me to ask about my virtual session—A Rat, A Rocket, and Science. As well as fun science, it includes literacy-building discussion on research, misinformation, and writing.

Canada's next Governor General - out of this world!

By Claire Eamer

Literally, she was out of this world. Twice! Julie Payette, who will take up the post of Governor General of Canada in the fall, is a scientist, an astronaut, and the first Canadian woman to board the International Space Station (ISS).

In fact, she helped build it. In 1999, she spent nine days as part of the second mission ever to the ISS. In a 2015 interview with Macleans Magazine, she said she thought of herself as a space construction worker. "We brought the first three tons of equipment, including some of the Imax camera stuff. We literally switched the light on to the station and walked in."

In 2009, Payette left Earth again, this time as flight engineer aboard the space shuttle. During that trip, she got to manipulate the giant, Canadian-designed robotic arms on the shuttle and the space station - Canadarm and Canadarm2. It was a tense assignment, she said in the Macleans interview: "When you're moving something on a a multi-billion-dollar structure, with people on board who count on that structure for safety and integrity, a mistake is not an option."

Payette has degrees in electrical engineering and computer science. She holds a commercial pilot's licence and is also a qualified pilot of military jet aircraft. She speaks English and French fluently, and can also carry on a conversation in Russian, Italian, Spanish, and German. And if that's not enough, she plays piano and has sung with several major classical music groups.

The 53-year-old Payette retired from the Canadian Space Agency in 2013, and became chief operating officer of the Montreal Science Centre. She left that job recently and will be sworn in as Governor General probably in late September or early October.

As the representative of the Crown in Canada, the Governor General performs the Queen's duties as set out in the Canadian constitution. It is a largely ceremonial role, but offers the person performing it plenty of opportunity to interact with Canadians in all regions and at all levels. Most recent governors general have used the opportunity to bring attention to an aspect of Canadian life that they feel strongly about.

In an interview with the Globe and Mail, Payette said it's still too early to say what her priorities will be during her tenure, but that they will include science and a knowledge-based society. As both a scientist and a science communicator, she is admirably equipped to take on that task.

Free Space Program Info from NASA

Rocket ships, telescopes, and astronauts! My computer brings me NASA's Astronomy Pictureof the Day and Image of the Day. NASA's space program has been fascinating since I was a child. These days, it's interesting in more ways, and the information is much more accessible than it ever was.

 and docking maneuver with the lunar module. Credits: NASA
 
Did you know that since it was founded, NASA makes heaps of learning materials available for free? Fifty years ago, there were only newspaper articles for me and my brother to read about the Apollo program. We watched the moon landings on our family's black-and-white television. Then in a science magazine we found the mailing address for NASA. In reply to our questions about astronauts, NASA sent us free pamphlets and posters and booklets. We sent blank videotapes and got back recordings about Mars and Venus probes. We were the space program experts at our school back then! 
 
That same feeling of “kid in a candy store” is what I get today at NASA's website at nasa.gov . It's wonderful to see the photos and videos of images from telescopes and from probes that visit other planets. Banners at the top of the screen organize links to many pages on different topics. When I wanted detailed articles to read on Curiosity Mars rover, it was easy to find information. Social media links are there, for daily updates from NASA on current events such as the Pluto fly-by. I even found podcasts and ebooks to download for my phone and tablet, and ringtone mp3s for my spouse to mix into Acid music loops! There is material of interest for people of every age or reading level, and particular attention is paid to teachers and students. For young children, there are NASA Space Place at http://spaceplace.nasa.gov/ and NASA Kids Club.

This Jan. 19, 2016, self-portrait of NASA's Curiosity Mars rover shows the vehicle 
at "Namib Dune," where the rover's activities included scuffing into the dune with a wheel 
and scooping samples of sand for laboratory analysis.

I'll never forget watching the dawn sky from an isolated farm north of Edmonton as the space station went by, and feeling connected to the space program because I looked it up at https://spotthestation.nasa.gov . The information NASA gathers on Earth and in space is for everyone. International scientists study data and draw conclusions that are wide-reaching. Doctors in Canada's North use monitoring and communications systems originally developed for astronaut safety. Artists are inspired by images and ideas from programs that study the solar system and galaxies.

We may never know how many people are helped by NASA making this knowledge available. You can look at NASA's web pages on Benefits To You to get some idea of the impact. The weather data alone is priceless. As for my brother who made an astronaut costume for Hallowe'en, he grew up to test computer games and security programs, and edit Neo-opsis Magazine. I'm the author of over two dozen books on science for educational publishers. With my friends and colleagues I write for our blog Sci/Why which has a list of family-friendly science books you can find in the left-hand column on this page. Whenever someone says they want to know more about astronomy and the space program, I send them to NASA's website for all kinds of information.
