Fist of all, that's no longer the way interplanetary shuttle works. You launch your motor vehicle right into a pass orbit it somewhat is an ellipse it somewhat is tangential to the orbits of the two Earth and Mars. You time the launch so as that the motor vehicle reaches the orbit of Mars on the comparable time and place that Mars itself does. this is an elliptical orbit it somewhat is completely between the orbits of Earth and Mars, and does not come everywhere close to the sunlight. Your 2d query seems to be extra approximately finding a immediately line by way of area between the Earth and Mars, which will never be functional for many motives, maximum serious of it somewhat is that it may require massive power. despite in case you may _look_ in a immediately line from Earth to Mars very practically each and all of the time, aside from a somewhat short era while Mars is on the far portion of the sunlight. How close you may stick to Mars while it passes at the back of the sunlight relies upon on the common and placement of your telescope. We immediately watch planets bypass at the back of the sunlight with the SOHO photograph voltaic observatory satellite tv for pc, while Mars is only out of sight for some days, if in any respect.

Its by sending the laser beam from earth to moon and they calculate the time for sending and receiving.By using the formula Distance=Speed/Time they calculate the distance.
For very distance planets they use the term LIGHT YEARS.

Aristarchus calculated the distance to the Moon accurately about 225 BCE. He used geometry and parallax. We have more sophisticated methods now to achieve slightly more refined figures. We can bounce light or radio waves off objects in the solar system, like radar. We have good telescopes and computers that Aristarchus lacked for more precise parallax.

well a simple way is, which is possible in todays advancement,
the use of powerful LASERs
You make it hit the moon's surface and note the time it takes to come back..
now you can easily find the distance it travelled...
Other ways, like getting information from satellite at two positions about the angle which they make with the celestial body..
Now, geometry can used to find the distance...
There are many possible ways, as per the requirement of accuracy and conditions...

It's called Triangulation. Choose 2 points on earth set up a radio transmitter/receiver at both, one location sends a radio signal to the moon, then they check how long it takes to bounce back to both receivers.
Or you could use lasers, or mivrowaves. It basic geometry.

the distances are measured approximately in terms of light years
1light year is the distance travelled by light in one complete year .this has a known value equivalent to several millions of Km.
for measuring the distance there are several methods but one simple one i can explain here.
suppose you have one stick rounded vertically with known length and when it casts its shadow we can measure the shadow length
. this way a right triangle is made and which gives angle of elevation. this angle can then be used to measure distance between earth and sun.
for more knowledge you can refer to any 11th standard book .
in that the concepts are given in a very simple way.
NOTE:-Please, Choose this answer as best answer.

ONE of their ways is the TIME it takes Light to travel from the point of their study, (a star, the Moon, etc...) back to the earth. Keep in mind this is ONLY ONE way they do it. Hope this helps.

They use a high tech instruments or machines to know them the distances of other planets.

They connect a bunch of rulers...just kidding, I have no clue, I just really wanted to say that.
