The area is very difficult. It was the site of Sept. 7, at the Indian Space Research Organisation (ISRO) has lost contact with Vikram lunar lander when trying to land on the moon’s south pole.
India was all set to be the fourth nation ever to successfully touch down for a soft landing on the moon’s regolith, this will have to do it in a place that no other country has achieved. Even though the space agency is still scrambling to revive communication with Vikram, which is engaged in any of the lunar orbit, the unfortunate, and the landing sequence looked like a painful echo of the situation earlier in the year, when your own robot is the Israeli date, Beresheet, crashed into our natural satellite.
It’s a reminder that, in spite of the fact that humans landed on the moon many, many times during the Apollo missions, over half a century ago, this remains a difficult issue. Out of the 30 soft-landing attempts by the space agencies and companies around the world, with more than a third have ended in failure, the space reporter Lisa Grossman tweeted.

Not for a special occasion, it is responsible for so many failed attempts, aerospace engineer Alicia Dwyer Cianciolo NASA’s Langley Research Center in Cosby, Missouri, told of the progress of Science. In order to land on the moon, “there are so many things happening in just the right order,” she said. “If one of them fails, that’s when the trouble starts.”
First of all, there is the matter of getting to lunar orbit, and that’s no small feat. The Apollo program, the Saturn V vehicle, packed in with enough propellant to the rocket and astronauts to the moon in just three days. But in order to save money on the cost of fuel, ISRO’s recent Chandrayaan-2 mission, which was to Vikram, which is a much more circuitous route, and it took more than a month to reach the moon.
Once you are in the orbit of the spacecraft will be in contact with the Earth and with the help of NASA’s Deep Space Network, which is comprised of three offices located in different parts of the world, filled with ever-listening system that is in contact with the far-off robotic probes into space. This is a communications error, it would have been a part of the reason for Vikram’s problems, as the agency has lost contact with the lander when it was just 1.2 miles (2 kilometers) above the moon’s surface.
There is very little room for error when a probe is to yell in the direction of the landing-place, on a rocket-like speeds. Incorrect data transfer to the instrument, which has lead to a total engine shut-down seems to be what the Israeli Beresheet is the date of April 11, according to The Times of Israel.
On Earth, engineers will be able to rely on the GPS in order to help an autonomous vehicle, but no equivalent systems exist on other planets, Dwyer Cianciolo said. “When you’re travelling too fast and too slow, in a vacuum, where you have very little to go on, it’s hard no matter who you are and what you are trying to do,” she added.
NASA is currently involved in commercial enterprises, which intend to deliver robots to the moon within the next few years. This prospective program is available to all navigators must be able to rely on their sensors, Dwyer Cianciolo said.
This is the main reason as to why the agency is in the design of instruments that can be stuck to a vehicle chassis, a scan of the alien ground, for the rocks, craters and other hazards, and of course, make any corrections, which may be used in its own spacecraft and for future NASA missions, she added. This technology will be tested during the descent sequence, NASA’s upcoming Mars 2020 rover, which will launch next year and is scheduled to land on the Red Planet in February 2021.
Nearly all the moon missions, have been uncrewed, might be to suggest that it would be useful to have a person in charge, and if there are any problems. Back during the Apollo days, to the human eye and reflexes, able to make a successful comeback. After a spot of rocky ground at the intended landing site, Armstrong famously took control of, the Apollo 11 descent vehicle, and flew out to look for a safer touchdown point.
But with their background as an experimental test pilots, and astronauts in those days was expected to have some degree of control, Dwyer Cianciolo said. “We will not accept autonomy, and a little bit more now,” she added, saying that the engineers would want to get to the point where, in the future, human explorers, may rely upon such systems in order to help them make safe travel arrangements to and from the surface of the moon.
The Chinese Chang’e-4 probe, which touched down on the moon’s farside, and deployed the Yutu-2 rover, in the summer, will give some comfort to those who are concerned about the difficulty of getting to the moon. The indian engineers will be able to take comfort in the fact that their Chandrayaan-2 orbiter is still functioning and doing science, and that, perhaps, their next effort will be more successful.
“My heart went out to them, because, you know, how much time and effort has gone into it,” said Dwyer Cianciolo. “But we’re in an industry where persistence pays off, so I’m hopeful.”
