Planet Mars

On Mars, an object weighing 125 pounds on Earth would weigh approximately 47.5 pounds, due to Mars having only 38% of the gravity of Earth.

"After the Mars pathfinder landed on the planet Mars" is not a sentence. You must complete this sentence by making it read something like the following:

After the Mars pathfinder landed on the planet Mars, it took pictures of the geographical features.

Yes, it would be difficult for humans to survive on Mars due to the extreme environment, lack of atmosphere, and absence of readily available resources like water and food. Significant challenges such as radiation exposure, harsh climate conditions, and limited access to supplies would need to be overcome for long-term survival on the planet.

This question can't be answered unless the year is also specified.

You need to give a year since Earth and Mars take different amount of days to obit the sun they do not sync up in the same place year to year.

Phobos, Mars' closest satellite, come from the Greek word meaning 'fear', whilst Deimos means 'panic', both following on from the Mars/War theme. Orbiting at a meagre 6000km from the surface of Mars, Phobos is the closest moon to its' parent planet in the Solar System (at least that we know of), whilst Deimos is the smallest known solar system satellite.

Phobos and Deimos are both believed to be captured asteroids, due to their irregular shape and small size (Phobos having a 22.2km wide diameter, whilst Deimos is just 12.6km wide!). Both moons are, however, heavily cratered and are believed to be made up of rock and ice. Like our moon they have a coating of dust on their surfaces. Phobos' orbit is such that it rises in the west and sets in the east, often more than once in one day.

However, I'm afraid there isn't realy much future left for Phobos as an independent moon of Mars. This is because in little over 50 million years it is destined to crash into Mars (with a thud) due to the planet's tidal forces lowering its orbit (presently at about 1.8cm/year). Nevertheless, it (and Deimos) have been seen by many spacecraft since it was discovered by Asaph Hall in 1877, such as the Mariner 9, Viking 1, Phobos and Phobos 2, the last of which even detected an outgassing coming from Phobos.

Mars sidereal rotation is 1.025 day

Earths sidereal rotation is 0.997 day.

Mars rotates on its axis at a speed similar to Earth's,averagiung 25 degrees,although in the past that angle has been as great as 60 degrees. This means that Mars,like Earth,has distinct seasons

Johannes Kepler was the first to accurately measure the orbit of Mars in the early 17th century based on observations made by Tycho Brahe. Kepler's work laid the foundation for his laws of planetary motion.

The Valles Marineris looks like exactly what it is - a long, deep valley. The same is true of Olympus Mons: An enormous, extinct volcano. Those are the two most prominent surface features. Most of the rest of Mars looks like a vast, windswept desert.

No, Mars is very cold. Venus would be the "hottest" planet.

--Constant hottest temperatures: Venus (Due to sulfuric acid causing greenhouse effect AKA intense global warming)

--Hottest Temperatures: Mercury (due to proximity to sun)

The planet between Mars and Jupiter is called the dwarf planet Ceres. It is the largest object in the asteroid belt and was reclassified as a dwarf planet in 2006. Its diameter is approximately 940 kilometers.

Iron oxide is a reddish-brown compound commonly referred to as rust. Polar ice caps are regions of a planet's surface where ice permanently accumulates. The presence of iron oxide in polar ice caps can give them a reddish color, like the red snow in Antarctica caused by iron-oxidizing bacteria.

A Martian solar day, or "sol", is a bit under 24 hours 40 minutes. The length of the "day" part of that vs. the "night" part depends on the latitude and time of year, the same as it does on Earth.

The object that is abundant between the orbits of Mars and Jupiter is called an asteroid. These are small rocky bodies that orbit the Sun and are remnants from the early solar system formation. The asteroid belt is located between the orbits of Mars and Jupiter.

Mars has a very thin atmosphere composed primarily of carbon dioxide.

Mars cannot orbit the earth. It orbits the Sun aprox. every 2 Earth years.

Two chief reasons :

low mass = low gravitational attraction.

no magnetic field around Mars ... thus solar wind strips air, so water evaporates faster, and water molecules are also subject to solar wind erosion.

Landers are spacecraft designed to land on the surface of celestial bodies such as planets, moons, or asteroids. They are used to gather scientific data, like analyzing soil samples, studying the atmosphere, or taking images of the surface. Landers are an essential part of space exploration missions to better understand the conditions and composition of other worlds.

Mars has lots of dessert , i don't mean the kind that you get in cafe's although chocolate ice cream is real nice. Mars has lots of crates ,volcanos,ice caps and maybe some small oceans. You can count on this answer because we have learnt about this in school and my teacher is a very brainy woman. although if you don't like this answer then look in a book and it will give you the same answer. when i typed that sentence i did not mean it in a rude or mean way so don't take it the wrong way.

Scientists still hope that Mars may have life of some kind; it would be an exciting discovery!

Some reasons why Mars is unable to form EARTH life forms would be the lack of an oxygen atmosphere and the lack of water except possibly as ice in the polar regions.

Just short of 687 Earth days in one martian year (686.971).

The diameter of Mars is approximately 6,779 km (4,212 miles), making it about 0.532 times the diameter of Earth.

No. Mankind not any spacecraft made it to Mars until 1971.

The landscape of Mars is characterized by vast plains, towering mountains, deep canyons, and impact craters. The planet also has polar ice caps composed of water and carbon dioxide ice. Some regions show evidence of ancient river valleys and lakes, indicating the presence of liquid water in the past.

• The most extreme cold on the planet.
• A very thick ice sheet.
• Isolation from any town, city or industrial development.
• Having to cross the roughest seas on the planet to get any cargo back to the industrialized world.
• Gigantic icebergs like multi-million tonne ploughs that threaten shipping, platforms and pipelines.
• The annual "icing-in" of the continent when the area around the coasts freeze so that only the most powerful (and expensive) ice breakers can get through.

  Antarctica is occupied by a succession of visitors, measured in thousands in the summer and hundreds occupying the various scientific bases in the winter.
