Rewrite this information as a series of diary entries by an astronaut preparing for, experiencing, and reflecting on a journey to Mars.

Mars is much colder than Earth, in large part due to its greater distance from the sun. The average temperature is about minus 80 degrees Fahrenheit (minus 60 degrees Celsius), although it can vary from minus 195 F (minus 125 C) near the poles during the winter to as much as 70 F (20 C) at midday near the equator.

The carbon-dioxide-rich atmosphere of Mars is also about 100 times less dense than Earth's on average, but it is nevertheless thick enough to support weather, clouds and winds. The density of the atmosphere varies seasonally, as winter forces carbon dioxide to freeze out of the Martian air. In the ancient past, the atmosphere was likely significantly thicker and able to support water flowing on the planet's surface. Over time, lighter molecules in the Martian atmosphere escaped under pressure from the solar wind, which affected the atmosphere because Mars does not have a global magnetic field. This process is being studied today by NASA's MAVEN (Mars Atmosphere and Volatile Evolution) mission.

NASA's Mars Reconnaissance Orbiter found the first definitive detections of carbon-dioxide snow clouds, making Mars the only body in the solar system known to host such unusual winter weather. The Red Planet also causes water-ice snow to fall from the clouds.

The dust storms on Mars are the largest in the solar system, capable of blanketing the entire Red Planet and lasting for months. One theory as to why dust storms can grow so big on Mars is because the airborne dust particles absorb sunlight, warming the Martian atmosphere in their vicinity. Warm pockets of air then flow toward colder regions, generating winds. Strong winds lift more dust off the ground, which, in turn, heats the atmosphere, raising more wind and kicking up more dust.

These dust storms can pose serious risks to robots on the Martian surface. For example, NASA's Opportunity Mars rover died after being engulfed in a giant 2018 storm, which blocked sunlight from reaching the robot's solar panels for weeks at a time.

Mars lies farther from the sun than Earth does, so the Red Planet has a longer year — 687 days compared to 365 for our home world. The two planets have similar day lengths, however; it takes about 24 hours and 40 minutes for Mars to complete one rotation around its axis, versus 24 hours for Earth.

The axis of Mars, like Earth's, is tilted in relation to the sun. This means that like Earth, the amount of sunlight falling on certain parts of the Red Planet can vary widely during the year, giving Mars seasons.

However, the seasons that Mars experiences are more extreme than Earth's because the Red Planet's elliptical, oval-shaped orbit around the sun is more elongated than that of any of the other major planets. When Mars is closest to the sun, its southern hemisphere is tilted toward our star, giving the planet a short, warm summer, while the northern hemisphere experiences a short, cold winter. When Mars is farthest from the sun, the northern hemisphere is tilted toward the sun, giving it a long, mild summer, while the southern hemisphere experiences a long, cold winter.

The tilt of the Red Planet's axis swings wildly over time because it's not stabilized by a large moon. This situation has led to different climates on the Martian surface throughout its history. A 2017 study suggests that the changing tilt also influenced the release of methane into Mars' atmosphere, causing temporary warming periods that allowed water to flow. 

The first person to observe Mars with a telescope was Galileo Galilei, in 1610. In the century following, astronomers discovered the planet's polar ice caps. In the 19th and 20th centuries, some researchers — most famously, Percival Lowell — believed they saw a network of long, straight canals on Mars that hinted at a possible civilization. However, these sightings proved to be mistaken interpretations of geological features.

A number of Martian rocks have fallen to Earth over the eons, providing scientists a rare opportunity to study pieces of Mars without having to leave our planet. One of the most controversial finds was Allan Hills 84001 (ALH84001) — a Martian meteorite that, according to a 1996 study, likely contains tiny fossils and other evidence of Mars life. Other researchers cast doubt on this hypothesis, but the team behind the famous 1996 study have held firm to their interpretation, and the debate about ALH84001 continues today.

In 2018, a separate meteorite study found that organic molecules — the carbon-containing building blocks of life, although not necessarily evidence of life itself — could have formed on Mars through battery-like chemical reactions.

Robotic spacecraft began observing Mars in the 1960s, with the United States launching Mariner 4 in 1964 and Mariners 6 and 7 in 1969. Those early missions revealed Mars to be a barren world, without any signs of the life or civilizations people such as Lowell had imagined there. In 1971, Mariner 9 orbited Mars, mapping about 80% of the planet and discovering its volcanoes and big canyons.

Diary Entry 1 - January 1, 2023
Preparing for our mission to Mars. She's a colder planet than Earth due to her greater distance from the sun. Her average temperature stays around -80°F. But things get even more extreme with temperatures reaching -195°F near the poles during winter. However, during midday near the equator, it can become quite bearable at 70°F.

The Martian atmosphere is rich in CO2 but about 100 times less dense than ours. Interestingly, it's thick enough to support weather, clouds, and winds. Seasonal variations cause carbon dioxide to freeze out of the Martian air during winter. Some say, in the past, the atmosphere was likely denser, capable of supporting flowing water.

Over time, lighter molecules in the Martian atmosphere have escaped, largely due to pressure from the solar wind. Mars lacks a global magnetic field, so the atmosphere is affected more directly. NASA's MAVEN mission is studying this process currently, uncovering more mysteries of our destination.

Diary Entry 4 - May 20, 2023
NASA's Mars Reconnaissance Orbiter has found carbon-dioxide snow clouds, making Mars unique in our solar system. Mars' winters are not just chilling but also dust-ridden. Dust storms there are the largest known, capable of blanketing the entire planet and lasting for months. This results from airborne dust absorbing sunlight and causing wind. I hope our equipment can withstand this Martian fury.

Diary Entry 5 - July 10, 2023
We have finally arrived at our destination after about seven months. Mars has a longer year compared to Earth due to its farther distance from the sun — 687 days compared to our 365. Days there are nearly identical to ours, with a complete rotation taking about 24 hours and 40 minutes. This will surely help us in maintaining our Earth-based routines.

Diary Entry 6 - August 25, 2023
Mars, like Earth, experiences seasons due to its axial tilt. The difference is, Martian seasons are more extreme. When Mars is closest to the sun, its southern hemisphere gets a short, warm summer, and the northern one gets a short, cold winter. When farthest, it's the other way around. This celestial ballet will be something to behold.

Diary Entry 7 - October 1, 2023
Still getting used to the environment here. The Martian axis tilt isn't stabilized by a large moon like Earth's. It has led to different climates on Mars throughout its history. A study suggests that the changing tilt might have caused temporary warming periods that allowed water to flow, releasing methane into Mars' atmosphere.

Some even mistook geological features for long canals, hinting at a possible civilization. We are, in a way, stepping into the footprints of these early observers.

Diary Entry 9 - December 30, 2023
Like several Martian rocks have made their way to Earth, our return home will also provide scientists with information for unique study opportunities. Although not like the rock Allan Hills 84001 (ALH84001) that was found in 1996 and believed to contain potential evidence of Mars's life, this expedition still contributes significantly to our understanding.

Diary Entry 10 - February 10, 2024
Reflecting on this mission manned mission, we have certainly come a long way since the robotic exploration of Mars that began in the 1960s. Early missions like Mariner 4 and Mariners 6 and 7 revealed Mars as a barren world. Later, Mariner 9 orbited Mars, mapping about 80% of the planet and discovering its volcanoes and grand canyons. Our journey continues this legacy of discovery, bringing humanity closer to Mars. We look forward to touching back down on Earth soon.
