What is the meaning of 'Have you ever been bonded'?

The concept of employee bonding is really an insurance matter relating to the employer’s efforts to protect itself against wrongful acts by its employees. In industries where employees have direct access to money or to property, the employer will often be keen to protect itself against the impact of employee theft.

Also, certain businesses will be required by their customers to provide proof that they are bonded. For instance, customers of commercial cleaning companies might demand the cleaners be bonded. This provides both peace of mind (that the cleaners are trustworthy) and financial protection in the event of theft.

How long does it take to get to Mars from Earth?

Unmanned probes from Earth can take from 7 months to two years to reach Mars, depending on when they are launched and how fast they can travel. The direct distance can vary from about 58 million kilometers to more than 400 million kilometers.

The distance is at least 36 million miles (58 million km).

So the minimum time would be:

At 70 MPH -- 56 years

At 500 MPH -- 8 years

At Mach 1 (0.34 km/sec) -- 5.4 years (5 years, 5 months)

At 40,000 MPH (fastest Voyager speed) -- 38 days

Manned Missions

The most commonly offered figure is "Six months there, and six months back". That is based on current (2012) technology, and there are currently no solid plans for a manned flight to Mars. By the time man does inevitably make a manned flight to Mars, there may be newer technologies in space travel that shorten the travel time.
The travel time to Mars would depend on the relative position of the planets in their orbits. The shortest time at closest approach, given current rocket propulsion, is about 7 to 8 months. This is the estimated transit time for the Mars probe of December, 2011.

It is possible to get there faster using more powerful rockets, but this would only reduce the time to 2 months at best (48 days at 30,000 mph). The round trip time could be 6 months or more, unless the mission waited for the next close alignment of the planets, which occurs every 26 months.
Travelling to mars can take anything form 3 to 9 months based upon 2 aspects. Firstly, it depends how far away Mars is away from Earth because as you already know, an obit is not completely circular, ; the pathway is more of an elliptical shape and the second point is how fast your space craft is going; the average speed a rocket or space shuttle can go is 7 miles per second.
Unmanned probes from Earth can take from 7 months to two years to reach Mars, depending on when they are launched and how fast they can travel. The direct distance can vary from about 58 million kilometers to more than 400 million kilometers.

The proposed NASA manned mission estimates about 200 days to reach Mars and 200 days to return. But one trip would take much longer unless the mission stayed on Mars for a year until the planets were again lined up in relation to their orbits. The actual yearly minimum distance is from 60 to 100 million kilometers.
Unmanned probes from Earth can take from 7 months to two years to reach Mars, depending on when they are launched and how fast they can travel. The direct distance can vary from about 58 million kilometers to more than 400 million kilometers.
The space probes launched to Mars take about 260 days (8 to 9 months) to reach Mars. Some high-speed transfer orbits could make the trip in as little as 130 days using current propulsion technology.
Depends on the propulsion. Under typical rocket power, upwards of 4 months if launched at the right time. With ion propulsion, it could take as little as 38 days to reach Mars.
It could take as little as 6 months or so. The most recent spacecraft to be sent there took 10 months (Pheonix), so its likely that a spacecraft carrying humans may go a little faster to limit the amount of time in space.
7 months if travelled by a satellite/space probe. But 3 years if done with someone actually in the rocket. .
Approximately 2 years one way.

What is Mars made of?

Mars is made of rock and iron oxides. It's surface is covered in mountains, volcanoes, valleys, ice caps and dried up river beds. Mars is also very dry like a desert. It is also red because of the iron oxide in the pulverized rock dust.
Mars is a planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, deserts and polar ice caps of Earth.

What are the minimum and maximum temperatures on Mars?

The temperature is typically about -63 oC (-81 oF). However, the equatorial regions of Mars may occasionally reach temperatures of up to 30-40 oC (50-68 oF), while during the long polar nights, the temperature can fall to around -120 oC (-184 oF). Suffice it to say, it gets cold.

Depending on Mars orientation to the Sun (Year) and it's axial rotation (Day) it's temperature can vary.

  • Min: 186 K, −87°C, -125°F
  • Max: 293 K, +20°C, +68°F
  • Mean: 210 K, -63°C, -81.5°F

Punctuation and Capitalization

Do you capitalize martian?

No. The word martian is a common noun. Common nouns are not capitalized unless there is another reason to do so, such as beginning a sentence or being part of a title.

Comments: I think "Martian" should be capitalised, but I don't think there's a strict rule about it. I think Martian is usually an adjective from the "proper noun" Mars.

Perhaps someone knows better.

What are two reasons why mars is a cold planet?

1. Mars is considerably farther from the Sun than Earth and therefore receives less sunlight to warm it.

2. It's atmosphere is very thin, so it cannot produce a substantial greenhouse effect and quickly loses the heat it gains in the daytime at night becaus the atmosphere is too thin to hold onto it.

Why is Mars a barren planet?

The same reason as all the other barren planets. There is no water, temperature is not right for life, etc.

Will we see the planet Mars and Moon side by side on August 27 2010?

No. On August 27, 2010, the Moon will be 4 days past the full, rising at about 11 PM. Mars is low in the western sky at sunset, near Saturn and Venus, so they are about as far apart in the sky as they could be.

What is the communication delay between earth and mars?

Given the following approximate radii for Earth and mars orbits:

Earth = 149,598,261 km

Mars = 227,939,150 km

The shortest distance between the two is the difference between the two,

which yields 4minutes 21seconds for radio to go that distance.

The longest distance between the two is the sum, which yields 21minutes.

Is there any chance of life on mars?

Yes! although there are minor chances of life on Mars but still hope is there. according to scientists and pictures sent back by the Mars Rovers, there are clear signs that once water did did did flow on the surface of red planet. so if there was water,there may well be life still. somewhere deep into the Martian surface, Bacteria might still be active. there are a lot of research going on that and also NASA plans to send first manned mission to the 4th planet as late as 2033.

Why do scientists think Mars and Europa are good places to look for signs of life?

Because Mars and Europa are considered two of the most likely places to find liquid water. Mars is thought to have tiny amounts of water that become liquid in it's soil, theoretically allowing some particularly resilient forms of bacteria to survive, and there may be relatively large bodies of water deep beneath Mars's surface. Europa is thought to have a global underground ocean (similar to the way Earth has an underground global magma "ocean") with a volume greater than all the water on Earth.

What is the weather generally like on mars?

At one point, the weather on Mars was similar to ours on Earth. Now, the weather is dry, hot, desolate, and very extreme. It's almost like living in complete isolated, untouched desert where it can be very hot in the day and very cold at night, just like our planet.

Why would you not live on mars?

because yo wouldn't be able to breathe. Two suggested ways to produce oxygen are to melt the polar ice that's deep underground so that it releases the trapped oxygen and/or to have gigantic greenhouses (and how to keep those plants alive). However Mars cannot hold a CO2 and Oxygen atmosphere for very long as it's such a small planet, eventually those elements would escape into space (not very long is relative, we're talking possibly millions of years here).

The best solution with our technology is to live in a relatively small surface station and use electrolysis on water to split it into oxygen and hydrogen gas. That is how the ISS produces oxygen, as well as a secondary system of pressurized tanks of oxygen. Here on Earth, oxygen is 21% of the atmosphere at sea level. It's important to maintain a proper balance.

Another hurdle is the solar radiation humans would be exposed to since Mars has a very weak electromagnetic field. That may prove the more difficult problem to overcome. The ISS, and other station in the past, have been so low in the atmosphere that Earth's EM field protects them for the most part (although there are times when radiation levels rise and they have to take shelter in a more shielded area of the station). We see on the movie Total Recall, that after the planet was populated with oxygen, people went outside the station onto the surface. In reality, that would be a bad idea.

What planet is called the Red Planet?

Mars is the "Red Planet".Mars is the red planet because it looks red with various oxides of iron (hematite mostly) in very, very fine particles, and trace amounts of other elements including titanium, chlorine and sulfur.
Mars is known as the Red Planet because of its rust color. Some time in the past Mars had an atmosphere with oxygen and something happened and the oxygen all went into the soil/rock which then became oxidized. This means it is theoretically possible for us to extract oxygen from the ground if a colony was ever sent to Mars.
The red planet is the nickname given to Mars because of its slight reddish appearance. You can see the reddish appearance with your own eyes, but the redness is due to a rusty layer and it is only a few millimeters thick.
Mars...Mars, the fourth planet in our solar system and the next planet out from us, is known as the "Red Planet" because of the high levels of iron oxide present on its surface which gives the planet a red hue.
Mars. It appears red, even from earth, due to the large amount of Iron Oxides on the surface.
Mars(a little on Jupiter) is the planet which is all red. It is red because it is rusty in colour and it is made out of iron.
Mars is known as the red planet. Mars appears red, even from earth, due to the large amount of Iron Oxides on the surface - a bit like rust.

What are Mars' rotation and revolution periods?

Mars' rotation period (the time it takes to spin once on its axis) is 24 hours 39 minutes and 35 seconds.

Mars' revolution period (the time it takes to make one orbit round the Sun) is 686.971 (Earth) days, which is the same as 1.8808 (Earth) years.
The rotation period of Mars is the time it takes to make a complete spin around its axis. (It takes a couple of minutes longer to make a complete day and night.) The rotational period of Mars is about 24 hrs and 37 mins (3% longer than an Earth day).

The revolution period of Mars is the time it takes to make a complete orbit around the Sun and to finish a complete year. The revolution period of Mars is 687 earth days (1.67 earth years).
Similar to Earth, or exactly 24 hours, 37 minutes, and 22 seconds.
