How long does it take for commands from Earth to reach a rover on Mars?

Probably a while because of the distance of Mars form the earth and how long it takes for radio waves and data to travel through space and be picked up by satellites.

How long does it take a message to travel from Earth to a spacecraft on Mars at its farthest from Earth about 400 million rm km?

We'll take your word for it and use the distance of 400 million km.

The speed of radio (and light, heat, UV, X-ray, etc.) is 300,000 km/sec.

Time = (400 x 106) / (300 x 103) = 1,333 seconds = 22.2 minutes

What is Mars atmospshere?

Mars's atmosphere is much thinner than that of the Earth, too thin to protect the planet against too low temperature, asteroids, and solar radiation. The air pressure at ground level on Mars is less than 1% that of the Earth. The Martian atmosphere has 4 main parts, lower, middle, upper, and exosphere, and the atmosphere is composed of the following gases:

• carbon dioxide (95.32%)

• nitrogen (2.7%)

• argon (1.6%)

• oxygen (.13%)

• carbon monoxide (.07%)

• water vapor (.03%)

• nitric oxide (.0013%)

• trace gases

How many days and years in mars?

A day on Mars is approximately 24.6 hours long, while a year on Mars is equal to about 687 Earth days.

How many known moons are on Mars?

Mars has two known moons named Phobos and Deimos. Both moons are relatively small and irregularly shaped, with Phobos being the larger of the two.

What is the average temperature of Phobos?

Temperature � 233 K is known as Phobos temperature.

The temperatures of Phobos, one of the moons of Mars,range from about −4 °C (25 °F) to −112 °C (−170 °F), on the sunlit and shadowed sides respectively.

What have scientist learned about Mars and its climate?

Mars has seasons just like Earth though they last about twice as long because the Martian year is almost twice that of Earth. Mars axial tilt is 25.2 degrees which is also very close to the 23.5 of Earth.

When a Martian hemisphere is experiencing summer, the polar cap shrinks back and may even disappear from view altogether. At the same time the darker regions grow darker and change slightly from year to year. It was once thought that these markings were vegetation, but we now know they are windblown dust.

When winter ensues, the polar cap of that hemisphere grows and may expand into the middle latitudes. The ice sheets of the polar caps are mainly carbon dioxide ice, but it is believed that there may be some water ice trapped underneath those sheets closest to the pole itself.

Generally Mars is quite cold with lows that reach -140 C (-220 F) but occasionally there are days that are quite balms reaching 20C (68 F.) Because soil and rock absorb heat from the Sun, the surface would be slightly warmer. Frost that forms during the night would melt and be released as water vapor during the day.

What is colder mars or Neptune?

Neptune is colder than Mars. Neptune is the eighth planet from the sun and is much farther from it compared to Mars, which is the fourth planet from the sun. Neptune's average temperature is around -353°F (-214°C), while Mars's average temperature is around -80°F (-62°C).

How much time does mars orbit the sun?

Mars takes about 687 Earth days, or 1.88 Earth years, to orbit the Sun once.

What is the difference between Ares and mars?

Ares is the God of War for the Greeks where Mars is the same except for the Romans. The difference here is that Mars was more revered by the Romans, and Ares was more hated. Ares was the God of War, Murder, and Bloodshed. Mars was the God of War, Agriculture, and (I think) food. What I am trying to get at was that Mars is seen as a God of Life, while Ares is seen as a god of death. The Roman soldiers prayed to Mars to support them in battle and what not. Hope this helps!

What is the distance from of the mars to the sun in AU?

It varies with each planet's position in its orbit. Mars is farther out from the Sun, and orbits more slowly than the Earth does.

At the "conjunction", when the two planets are closest together, they are about .5 AU apart. But 8 months later, when Earth has raced ahead and is now on the opposite side of the Sun from Mars, the distance is about 1.5 AU.

What are mars 2 moons named after?

Phobos, after the Greek god of fear - son of Ares (mars) and Diemos is named after a figure representing dread in Greek mythology. Mars was named after the god of war.
They are named after the sons of Ares. Ares is the Greek name for the god the Romans called Mars.

Are there tornadoes dust storms on Mars?

Tornadoes and dust storms on Mars are similar to those on Earth, but they can be much larger and more intense due to the planet's thin atmosphere and strong winds. Tornadoes on Mars are largely made up of dust and are known as dust devils, while dust storms can cover vast areas and last for weeks or even months. These phenomena are common on Mars and have been observed by various spacecraft and rovers.

What is the distance that mars is from the sun in kilometers?

The mean distance of Mars to the Sun is about 228 million kilometers. However the martian orbit is quite eccentric which leads to a difference of nearly 42 million kilometers between the furthest and the closest distance distance from the Sun.

Why is Olympus Mons famous?

Mars, the forth planet, has the volcano Olympus Mons. This is the largest volcano or indeed mountain in our solar system.

Olympus Mons was formally discovered when probes first flew to Mars but astronomers on Earth knew the feature due to the way it reflected light. They originally named it Olympus Nix (snow) but suspected that it may well have been a mountain.

Mount Olympus (as its name translates to in English) is nearly 17miles high. This makes it 2 and a half times the size of Mauna Kea but 3 times the size of Everest (Mauna Key is the tallest mountain on Earth. Everest is the highest mountain).

Olympus Mons was formed by slow volcanic action over many, many years. As there are no tectonic plates on Mars any weak spots in the crust remain in the same place allowing the formation of enormous volcanic mountains.

Olympus is the same type of volcano as Mauna Key.

Due to the sheer vastness of Olympus Mons you would be unable to see the top of it whilst climbing the mountain nor from a distance. If you were to stand on the top of the mountain you would be unable to see the bottom because it is so vast that it would continue beyond the horizon.

Is there uranium on Mars?

There has been no direct evidence of uranium on Mars so far. However, some studies suggest that there may be trace amounts of uranium in the Martian soil. Further exploration and analysis would be needed to confirm the presence of uranium on Mars.

What have the satellites around Mars found?

Satellites around Mars have found evidence of past water flow, ancient river valleys, ice caps, and seasonal changes in the planet's surface. They have also detected methane in the atmosphere and provided valuable data for studying the planet's geology and weather patterns.

How many times does mars circle the sun in a year calculated in earth years?

It takes Mars 687.0 days to make one orbit around the sun (or 1.88 times for every one earth year).

Do you think people will eventually land on mars?

Yes, with ongoing advancements in technology and space exploration efforts, it is likely that humans will eventually land on Mars. Several space agencies and private companies have plans for Mars missions in the coming years, so it is a realistic possibility.

When did the first space shuttle land on Mars?

The Space Shuttle never landed on Mars. In 1971, the Russian Mars 2 and Mars 3 probes were the first things to land on Mars.

What do you get when you cross a yack and a martian?

You get a "yackian", a fictional creature resulting from the fusion of a yak and a Martian. It's simply a playful and imaginative combination of the two distinct beings.

Why is It is not likely that any living organism could survive on the Martian surface?

The Martian surface has a thin atmosphere lacking sufficient oxygen for respiration and shielding from harmful solar radiation. Extreme temperatures, low atmospheric pressure, and scarce liquid water also make it unlikely for living organisms to survive on Mars without specialized equipment and protection.

Were there living things on mars?

There is no definitive evidence of current life on Mars. However, scientists have found evidence that suggests Mars may have had conditions conducive to supporting microbial life in the past. Ongoing research and exploration continue to search for signs of past or present life on Mars.

How many known satellites have gone to mars?

As of now, there have been a total of 24 known artificial satellites that have been sent to Mars by various space agencies and organizations. These satellites have been used for different purposes such as orbiting Mars, studying its atmosphere, surface, and geology, as well as facilitating communication between Earth and Mars missions.

Can mars's moons support life?

The two moons of Mars, Phobos and Deimos, are not considered capable of supporting life. They are both small and irregularly shaped with low gravity, lack of atmosphere, and harsh surface conditions. Life as we know it would not be sustainable on these moons.
