Ah, December 25th! While many on Earth are celebrating Christmas, the cosmos has its own celestial gift to offer on this day. Let's unwrap a significant astronomical event that occurred on December 25th:
On December 25, 2003, the European Space Agency's Mars Express spacecraft successfully entered orbit around Mars. This was a momentous occasion in the exploration of the Red Planet and a fantastic Christmas present for space enthusiasts and scientists alike!
Mars Express, launched on June 2, 2003, became Europe's first spacecraft to explore another planet in our solar system. Its primary mission was to study the Martian atmosphere, surface, and subsurface, searching for signs of water and potential past or present life.
The spacecraft carried with it a lander called Beagle 2, named after the ship that carried Charles Darwin on his famous voyage. Unfortunately, Beagle 2 was lost upon landing and wasn't heard from again until its remains were spotted by NASA's Mars Reconnaissance Orbiter in 2015.
Despite this setback, Mars Express has been an incredible success story. It's been orbiting Mars for over two decades now, far exceeding its planned mission lifetime. It's provided us with stunning high-resolution images of the Martian surface, detected methane in the planet's atmosphere (a potential biosignature), and made groundbreaking discoveries about water on Mars.
One of its most exciting findings came in 2018 when its MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) instrument detected a possible 20-kilometer-wide underground lake of liquid water near the planet's south pole. Talk about a cosmic ice fishing opportunity!
So, as we celebrate the holidays here on Earth, let's raise a glass of eggnog to Mars Express, the little orbiter that could. It's been tirelessly circling the Red Planet, unwrapping Mars's secrets like presents under a cosmic Christmas tree, and reminding us that even on familiar holidays, the universe always has something new and exciting to show us.
Who knows? Maybe one day, future Mars colonists will mark December 25th not just as Christmas, but as "Mars Express Day," celebrating the arrival of this pioneering spacecraft that paved the way for human exploration of the Red Planet. Now that would be a holiday party worth attending!
