How many missions have been successful on mars?

It is often said that almost half of the missions to Mars have failed. But it is difficult to give an accurate account of exactly how many campaigns were successful and how many failed. But why?

Scientists may be able to easily calculate the number of expeditions, they will also give a percentage, but the real complication in the scientific community is the criteria by which success and failure will be calculated.

Beagle-2 Mission:

For example, the British spacecraft Beagle-2 was able to successfully enter the Martian meteorite in December 2003. The spacecraft also successfully landed on the surface of Mars. But a few years ago, it was reported that the spacecraft failed to deliver the news of its successful arrival home, that is, to Earth. So this campaign failed or failed?

Pictures sent by NASA‘s Mars Reconnaissance Orbiter observation spacecraft show that parts of the Beagle-2 spacecraft, such as the “petals” that were supposed to open during landing, failed to open. Solar panels were attached to the petal-like parts. When they do not open, the communication antennas are closed and the spacecraft’s communication path with the earth is closed.

In the context of the Beagle 2-spacecraft, it is said that this space mission left only a few rubbing marks while landing on the surface of Mars – without any success. But is the fact that the vehicle landed unscathed at least partially a success? There are differences among scientists.

Mars-III Mission:

Russia’s Mars-III spacecraft. The spacecraft first successfully landed on Mars on December 2, 1981. That is the first landing of a spacecraft on Mars. Immediately after landing, the Soviet spacecraft began sending images from there to Earth. The controllers of the mission were overjoyed at this success.

But in less than two minutes on the surface of Mars, the spacecraft’s machinery became crippled. At that time there was a terrible dust storm. It is believed that the dust storm was the reason why the spacecraft’s machinery became useless.

Some scientists believe that the dust storm disrupted the spacecraft’s electrical system and disrupted the spacecraft’s communication with Earth. After the Soviet Union sent spacecraft to Mars five more times, their missions saw real success.

So Mars-Three: Success or Failure? There was no consensus on this either.

There is one more thing:

what will the expedition to Mars actually be called? In 1986, the Soviet Union sent two spacecraft – their main purpose was to gather and research information about the two moons of Mars, Phobos and Demos. However, one of the goals of the mission was to bring information by observing the planet as well.

Phobos-1 :

Phobos-1 could not reach Mars due to a mistake. A few months later another spacecraft was sent to fetch information about Phobos, which was also lost in space. Attempts to send another mission to Phobos in 2011 also failed.

Many people questioned whether the spacecraft sent to Phobos was sent to Mars. As a result, is it right to consider them as Mars research missions? Others say no, they should be included in the list of missions to Mars. The answer to this question is also unclear. What do you think? Please write the comment section below…..

In addition, some missions such as NASA’s Dawn and the European Space Agency’s Rosetta spacecraft have touched down on Mars on their way to their “real” destination. So which list should their names be on? Probably a factor as to why they’re doing so poorly: “Some half of the spacecraft have been successful and the other half have been unsuccessful.

But they can’t give a clear idea of ​​which were the original Mars missions, and which were sent to work around Mars. However, the missions whose names appear on the list of failed operations were largely due to technical glitches, software problems, and in some cases mere misfortune.

Climate Orbiter Mission:

NASA sent a spacecraft called the Mars Climate Orbiter Mission to Mars in 1998, there was an unprecedented discrepancy in the way the data would be calculated. Whether the spacecraft’s data will be recorded in the metric system or in the traditional way, it gets confused when the spacecraft enters the orbit of Mars. It is thought that the spacecraft was either burned to the ground in the atmosphere of Mars or that it crashed into the Sun’s orbit and crashed.

Many again think that this campaign was an attempt to do more work than was allocated for the campaign. NASA’s motto at the time was three things – fast work, improved work, and cheap work. Scientists joked that it was impossible to match the three together – whichever one was chosen.

Despite that, and with the exception of some failures, America’s record of success on the Mars mission is the best.

More Mission:

Not only have all the spacecraft NASA sent to Mars since 1999 been successful, but those missions have long worked to gather additional information beyond the purpose for which they were sent.

At the moment, NASA has sent the spacecraft Perseverance to Mars. The United Arab Emirates and China have also sent their spacecraft to Mars. It remains to be seen whether their names will be on the list of successes or on the list of failed campaigns.
