Solar Storm Causes Quebec Blackout

A massive geomagnetic storm caused a catastrophic blackout in Quebec, Canada. This was a wake-up call for infrastructure vulnerability to space weather.

First Spacewalk by Alexei Leonov
On March 18, 1965, Soviet cosmonaut Alexei Leonov made history by becoming the first human to conduct a spacewalk, or extravehicular activity (EVA), during the Voskhod 2 mission. Leonov exited the spacecraft for approximately 12 minutes, tethered by a 5.35-meter cord. The event marked a turning point in human spaceflight, proving that astronauts could survive and work outside their spacecraft in the vacuum of space. However, the mission nearly ended in disaster. Leonov’s suit ballooned in the vacuum, preventing him from re-entering the airlock. Thinking quickly, he manually released some of the suit's pressure, risking decompression sickness. He barely made it back into the capsule, drenched in sweat. The mission also faced a rough manual landing in the Ural Mountains. Despite these challenges, the mission was heralded as a triumph and a critical step toward lunar exploration and space station construction. Leonov's bravery and ingenuity made him a Soviet hero and a legend in the history of human spaceflight.

Solar Storm Causes Quebec Blackout
On March 18, 1989, a massive geomagnetic storm—triggered by a coronal mass ejection from the Sun—struck Earth, causing a catastrophic blackout in Quebec, Canada. The storm began with a burst of solar particles hitting Earth's magnetosphere, generating powerful electrical currents in the planet’s upper atmosphere. These geomagnetically induced currents overwhelmed Quebec’s power grid, knocking it offline within 90 seconds and leaving over 6 million people without electricity for up to 9 hours. The event was a wake-up call for the vulnerability of modern infrastructure to space weather. It also disrupted satellite communications and caused issues for airlines and military operations. The blackout highlighted the need for improved monitoring of solar activity and better resilience in electrical grids. The 1989 storm remains one of the most powerful and disruptive space weather events in recorded history and serves as a cautionary tale as our dependence on technology continues to grow.

CUPS OF COFFEE DRANK IN THE PROCESS.

We created this project

to celebrate the rich timeline of

space exploration and

astronomical discoveries,

one day at a time.

Whether it’s the launch of a

legendary spacecraft,

the discovery of a distant moon,

or a historical mission milestone —

we believe every space event deserves

to be remembered.

"This Day In Space" is more than a calendar.

It’s our way of connecting people with

the vast, beautiful history of the universe. With each entry,

we aim to spark curiosity, awe, and

a sense of wonder about the cosmos.

SO WE CHASED COMETS,

DANCED WITH ECLIPSES,

CHARTED CENTURIES THROUGH STARS,

AND NAMED MYTHS ON MOONS.

NOT BAD FOR A TIMELINE,

MEASURED IN COSMIC FOOTSTEPS.

IF YOU'RE STILL READING THIS—

I GUESS SPACE DID HOLD YOUR ATTENTION
