Named after the Roman God of war, Mars is the fourth planet from the sun in our planetary group.
Mars is otherwise called the 'Red Planet' since, all things considered, it's red! This mark shading comes from the enormous measure of a substance called iron oxide (or 'rust' as you may know it) in its stones and soil.
Mars is the second littlest planet in the planetary group after Mercury. With a breadth (distance through the center) of 6,791 kilometers, it's generally a large portion of the size of Earth.
It can get pretty cold on Mars – a lot colder than our own planet since it's further away from the sun. At the equator, temperatures can arrive at 20°C, yet at its shafts, they can plunge to as low as - 140°C.
1) Mars soil contains an immense measure of water
If you heat a cubic foot of Mars soil, you can reap around two pints (one liter) of water. As per new information returned by NASA's Curiosity wanderer, this isn't only an oddball fortunate find, possibly: It appears to be that the greater part of the soil on Mars harbors a lot of water. This is exceptionally intriguing information for future human investigation of Mars since it's restrictively hard to ship water from the outer layer of Earth to the Red Planet — and, all at once, it additionally makes the possible terraforming and colonization of Mars much more practical.
This stunning discovering comes from information accumulated by Curiosity's Sample Analysis at Mars (SAM) on-board research center, which played out a progression of tests over half a month at the Rocknest site back in the fall of 2012. The SAM contains three instruments — the Quadrupole Mass Spectrometer (QMS), Tunable Laser Spectrometer (TLS), and Gas Chromatograph (GC) — yet it is the outcomes from this last instrument, the GC, that we are generally intrigued by.
Essentially, the GC warms up a dirt example by passing hot (~835C, 1535F) helium gas over it and afterward gauges the gases that arise. For this situation, by a long shot, the most well-known gas delivered (somewhere in the range of 1.5% and 3% by weight) was water fume. Per cubic foot of Mars soil, this likens to a great deal of water — around two pints, or just about a liter.
It's not all uplifting news, however. Alongside the huge measure of water, SAM's GC instrument likewise recognized huge measures of oxygen and chlorine, proposing that up to 0.5% of the diet comprises perchlorate compounds. Perchlorates are known to dial back human thyroid capacity, so it very well may be an issue for human travelers/pioneers in case there is a ton of perchlorate in the Martian climate.
These two discoveries come as a feature of the initial five companions surveyed papers distributed by Curiosity's many human researchers. The other four papers tackle themes, for example, the pyramidal mugearite rock named Jake Matijevic (presented above), and dig further into investigating Mars' dirt. There has been some contention over NASA's choice to distribute these papers in the paywalled diary Science when all works of the national government are unequivocally barred from copyright insurance and are, for the most part, distributed transparently. Luckily, Michael Eisen has downloaded the papers from Science and made them accessible for nothing on his site.
2) It isn't excessively cold or boiling.
Mars may look hot, but don't let its color fool you -- Mars is actually pretty cold!
In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm.
Mars also has a hard time holding onto the heat it does get. On Earth, much of the sun's heat gets trapped in our atmosphere, which acts as a blanket to keep our planet warm. But Mars' atmosphere is about 100 times thinner than Earth's -- so heat from the sun can easily escape.
How easily? If you were standing on the Martian equator at noon, it would feel like summer at your feet, but winter near your head!
At night, it's even worse: when the sun goes down, temperatures can plummet to negative triple digits! And beware of cold winter nights, when it could drop even lower!
So if you plan to visit, better bring a spacesuit to keep warm -- Mars really is a pretty 'cool' planet.
3) There is enough sunlight to use solar panels on mars
Like Mars Pathfinder, the Mars Exploration Rovers are sunlight-based controlled. Energy is assimilated through sun-based exhibits on boards that sit on what resembles the meanderer's "wings." They were intended to amplify the space of sun-oriented cells that gather the sun's energy.
One more development for the meanderers is the expansion of Triple Junction Gallium Arsenides. These three-layered sun-powered cells made their first outing to Mars onboard the twin meanderers. Utilized on NASA's Deep Space 1 mission, these cells can retain more daylight than the single-cell adaptations sent on Sojourner. The sun-oriented cells are stacked in three layers on the meanderer's sun-based exhibits. Because they i. Inre daylight, they can supply more capacity to the wthey anderer's re-chargeable lithium batteries.
The Sojourner wanderer on the Pathfinder mission conveyed one 40-amp-hour lithium battery. The Mars Exploration Rovers convey two 8-amp-hour lithium batteries. During the wanderers' superb missions, their sunlight-based exhibits had the option to deliver around 900 watt-long stretches of energy each martian day or sol. Well into the drawn-out mission, endeavors to drive Spirit and Opportunity deliberately through and toward sun-based rich regions are giving up to 410 watt-hours per Martian sol.
Utilizing sun-oriented force restricts the spots on Mars that landed meanderer missions can investigate. They are confined to landing and going around the tropical district to get sufficient daylight to re-stimulate their batteries. For future missions, NASA is thinking about substitute force sources to build the region on Mars that may be considered, opening up the entire planet to the investigation.
Mars is the most secure planet to make a trip to because: its dirt contains a little water; it gets sufficient daylight to utilize sun-oriented force; ... a day on Mars is practically a similar length as on Earth.
4) Gravity on Mars is 38% that of our Earth's, which many believe to be sufficient for the human body to adapt to.
It isn't excessively cold or boiling. There is sufficient daylight to utilize sunlight-powered chargers. Gravity on Mars is 38% of our Earth's, which acceptnumerous individuals accept to be adequate for the human body to adjust to. It has a climate (yet a dainty one) that offers insurance from inestimable and the Sun's radiation.
5) The day/night beat is basically the same as our own here on Earth: a Mars day is 24 hours, 39 minutes, and 35 seconds
Mars is a planet with a very similar daily cycle to the Earth.
Its 'sidereal' day is 24 hours, 37 minutes, and 22 seconds and its solar day is 24 hours, 39 minutes, and 35 seconds.
Therefore, aTherefore, a Martian day (referred to as “sol”) is approximately 40 minutes longer than a day on Earth.
