This is a wild moment inside the cockpit, just 2 minutes after leaving Florida. At 150,000 feet, the sky has gone from light blue to black, and the ride on the huge, solid rockets has been violent, jamming us up through the air. Suddenly there's a blast of pyrotechnics. Even though we're going Mach 5, the air is so thin the explosion arches out in front of the windows. Now being pushed by just the 3 Shuttle engines, the ride goes smooth, with a huge feeling of relief - getting rid of those solids means you're much safer, and halfway to orbit. I've done it twice, Atlantis and Endeavour. A great start to an amazing adventure.

There are several noises I'd prefer not to hear inside my spaceship, including this one that The Boeing Company Starliner is now making.

Testing the next gen lunar surface space suit. It's easy to climb into (through the back), has good mobility, the gloves work fine. We were evaluating the interfaces with the Astrolab rover - launching to the Moon later this year. Great to see and experience the new legacy of the Axiom Space suit in their Houston test rig.

How do rockets work? Sometimes I teach at university, and everybody likes a live demo. A fire extinguisher is just a small rocket nozzle; a chair & cart make a good spaceship. Folks ask how it works in space with no air to push against? But it's the mass blasting out that makes me roll. Doesn't need any backstop. Newton's 2nd law. But always good to have a landing plan - thanks University of Waterloo students!

Before I was an astronaut I was a test pilot, finding new ways to recover an F-18 after it went out of control. We learned a lot & made flying safer - but good to have an ejection seat, just in case.

Cecilia Chirenti & her team discovered this pair of spinning neutron stars smashing into each other, forming a single massive star, then collapsing into a black hole. The sound is gravitational waves. (from old NASA satellite data)

Flying the world's largest centrifuge. When manually piloting a space capsule back into Earth's atmosphere, it's easy to get to 8 times the force of gravity. In this 18m behemoth trainer, you feel the real forces as you maneuver. A well-flown reentry is about 4G, ballistic backup mode is 8 or 9G. The all-time worst was 21.3G during the Soyuz 18a launch abort - but they survived:

The best way to simulate weightlessness is to train underwater, in NASA's 40-ft deep Houston pool. The safety divers attach weights/foam to our spacesuits so the buoyancy is perfectly neutral, even when upside down or sideways. It's an art. When I got to orbit for my spacewalks, the years of preparation made it feel familiar; a good way to be for such a dangerous, amazing, otherworldy experience.

China just landed a probe on the far side of the Moon - this time nearer the south pole, to gather volcanic samples using a scoop and drill, and blast them back to Earth. They've partnered with Sweden, France and Italy. Proving the tech needed to land Chinese astronauts by 2030.

Business end of the space robot Canadarm2. Those internal snare wires grab a post (with a knobbed end), pull it inside, and then the outer connectors plug in for data, video, power. Canadarm has one of these on each end, so it can walk itself from post to post, like a huge space inchworm. I helped build Canadarm2 onto ISS during my spacewalks Canadian Space Agency NASA.

Making the seat that kept me alive. The artisans pour gypsum around my body, wait for it to dry, haul me out, and then sculpt a perfect mold of my butt. That mold is used to shape a polyurethane foam seat liner, covered in fire-resistant blue fabric. Comfy and supportive when we smack violently back into the world. Don't leave Earth without one.

Testing the next lunar rover. Fun to go to the hottest place on Earth to help develop Astrolab's FLEX vehicle. It has multiple cool new tech ideas, to be used when the FLIP version rolls on the Moon soon. Advances from both are being built into the CLV-1 Crewed Lunar Vehicle that NASA chose for Moon Base - will go over 6 mph, directly and remotely piloted.

Weightless fingernail trimming - bits go everywhere! So we cut them over a fan filter intake and vacuum them up when done (keeps someone from inadvertently breathing them, floating around). Note the velcro on the clippers, for 0G storage. And the loud ambient sound of living inside a spaceship.

Do you gain weight in space? How would you know? Obviously a weigh scale won't work when we're weightless. So we climb on an oscillating spring, and time the change in speed. From that, we can calculate our weight (or 'mass'). After 6 months I stayed the same mass, but lost fat & gained muscle with the healthy diet (no beer or pizza) and daily exercise. The most exclusive of all health spas :) image: Cady Coleman NASA

Immediately after launch there are lots of tasks. While Bones, John & Rommel reconfig'ed Endeavour for orbit, I took detailed images of our jettisoned external fuel tank, before it fell & burned up. If it was scarred, then our belly tiles were likely damaged: important to know, to try & fix before the heat of re-entry. Luckily it was clean, and we carried on to dock with the Space Station - an amazing day!

Being weightless changes so many things. Even crying. It also changes your digestion, blood flow, muscle & bone density, vision, balance - and height!

What song would you play onboard a spaceship? That's Thomas Reiter on the old Russian guitar & me on the SoloEtte, onboard Mir. Wishing we'd brought a tuner :) The floating maple leaves came from my elementary school, King George VI in City of Sarnia, pressed in my notebook. That foldable SoloEtte is now in the Canada Aviation and Space Museum in Ottawa. The Russian guitar had been transferred to Mir from the older Salyut-7 space station, and eventually burned up with Mir on reentry. Canadian Space Agency European Space Agency
