Space is exhausting. Honestly, if you spent six months living in a pressurized tin can orbiting the Earth at 17,500 miles per hour, you’d probably be a bit cranky too. But for the crew of the International Space Station, keeping energy levels high isn't just about drinking enough coffee; it's a matter of mission success and, frankly, survival. This is exactly why the Energizing Start 2 Expedition 33 protocols became such a pivotal moment in orbital history.
Most people think of Expedition 33 as "the one with Suni Williams," but it was so much more than a change in command. It was a massive experiment in human endurance.
What Energizing Start 2 Expedition 33 Really Got Right
When Expedition 33 officially kicked off in September 2012, the crew—consisting of Sunita Williams, Yuri Malenchenko, and Aki Hoshide—faced a daunting schedule. They weren't just "floating around." They were juggling the arrival of the first commercial resupply mission from SpaceX (the CRS-1) while maintaining a complex laboratory. The "Energizing Start" wasn't a single event. It was a secondary push—a phase two—of a physiological overhaul designed to prevent the mid-mission slump that usually hits around month three.
NASA’s Human Research Program had been watching data from previous increments and noticed a trend. Cognitive speed slowed down. Sleep quality plummeted. To fix this, Energizing Start 2 Expedition 33 focused on circadian rhythm realignment.
They didn't just turn the lights on. They changed the type of light.
By utilizing the newly installed LED Lighting Assembly, the crew could simulate the blue-light spectrum of a terrestrial morning. It sounds simple, right? It isn’t. In space, you see 16 sunrises a day. Your brain gets incredibly confused. By "energizing" the start of the duty day with specific wavelengths, the ground team at Johnson Space Center managed to stabilize the crew's cortisol levels. This wasn't some "wellness" trend; it was hard science applied to the most extreme environment known to man.

The SpaceX Factor and High-Stakes Fatigue
October 2012 was a mess of activity. The Dragon spacecraft was berthed to the station, marking a transition into the commercial era. Imagine the pressure. You’re tired, you’re hundreds of miles above the only place with breathable air, and you have to operate a robotic arm to catch a moving vehicle.
The Energizing Start 2 Expedition 33 initiative played a massive role here.
Instead of the old-school "work until you drop" mentality, Expedition 33 utilized "protected sleep blocks." This was a shift in philosophy. The energy didn't come from pushing harder; it came from structured recovery. Commander Sunita Williams often spoke about the importance of the crew's mental state during this transition. If the start of the day—the "Energizing Start"—wasn't handled correctly with proper nutrition and light therapy, the technical precision required for the Dragon berthing would have slipped.
Beyond the Lights: Nutrition as Fuel
You can't talk about an "energizing start" without talking about what these guys were eating. Forget the "pills and tubes" myth. By the time Expedition 33 rolled around, the food labs at NASA were getting serious about inflammatory markers.

Your bones are leaking calcium, and your muscles are trying to atrophy. To counter this, the Expedition 33 nutrition plan focused heavily on Vitamin D and Omega-3 fatty acids. They were looking for a sustained burn. Most people on Earth start their day with a sugar crash. An astronaut can't afford that. The "Start 2" phase emphasized complex carbohydrates that broke down slowly, ensuring that during long Extravehicular Activities (EVAs), like the one Hoshide and Williams performed to replace a Power Distribution Unit, they didn't hit a wall.
It worked.
During their spacewalks, the Expedition 33 crew showed remarkable stamina. They were outside for over six hours at a time. If you’ve ever tried to move your hands inside a pressurized glove, you know it’s like squeezing a tennis ball for six hours straight. The physiological prep paid off.
Why Most People Misunderstand "Expedition 33"
If you search for Expedition 33, you’ll see plenty of photos of the crew smiling. What you don't see is the struggle with "Space Fog." It’s a real thing. It’s a cognitive decline caused by CO2 buildup and fluid shifts to the head.
The Energizing Start 2 Expedition 33 protocols were specifically designed to fight the "puffy face" syndrome. By using high-intensity exercise—specifically the Advanced Resistive Exercise Device (ARED)—immediately following the morning light therapy, the crew forced fluid back down into their extremities. This cleared their heads. It gave them that "energized start" they needed to handle the complex science experiments, like the Alpha Magnetic Spectrometer, which was searching for dark matter.

The Lasting Legacy of the Energizing Protocol
What did we actually learn?
First, the "Start 2" approach proved that human biology isn't fixed. Even in microgravity, we can manipulate our energy cycles. Second, it proved that the "commercialization" of space requires a new type of astronaut—one who is as much a high-performance athlete as they are a scientist.
Expedition 33 ended in November 2012 when Williams, Hoshide, and Malenchenko landed their Soyuz TMA-05M in the dark, snowy steppes of Kazakhstan. They came back healthier than many previous crews. Their bone density was better. Their cognitive scores were higher.
The Energizing Start 2 Expedition 33 wasn't just a catchy name for a morning routine. It was the blueprint for how we will eventually send people to Mars. On a three-year journey, you can't afford a single "bad morning."
Actionable Insights for Terrestrial Energy
While you might not be orbiting Earth, the lessons from Expedition 33 apply to anyone working high-stress, high-consequence jobs:
- Master Your Light: Use high-intensity blue light (or sunlight) within 20 minutes of waking to reset your circadian clock. This mimics the NASA "Energizing Start" protocol.
- Buffer Your Stress: Schedule high-cognition tasks (like technical writing or coding) only after you’ve cleared "sleep inertia" through movement or light exercise.
- Inflammation Control: Follow the Expedition 33 lead by prioritizing Omega-3s and long-chain carbs in the morning to avoid the 2:00 PM crash.
- Protected Recovery: Energy is a finite resource. If you have a "SpaceX-level" project at work, you must guard your sleep blocks with the same intensity that NASA mission control does.
The success of the 33rd expedition proved that performance is a result of preparation, not just willpower. By focusing on the first 90 minutes of the day, the crew managed to bridge the gap between human frailty and the cold, demanding reality of the cosmos.
