आज विश्व के हर कोने में एक चर्चा हैं कि इसरो ने अचानक से ऐसा कैसे कर दिया जिस देश में आज भी बीमार व्यक्ति को 5 -5 किलोमीटर तक चारपाई पर रखकर अस्पताल तक पहुँचाया जाता है उस देश के बैज्ञानिकौ ने चांद पर अपना यान सफलतापूर्वक कैसे भेज दिया
चांद पर यान भेजने का मतलब है भारत एक शक्तिशाली देश बन गया है जहाँ तक रोवर से पुनः सम्पर्क स्थापित करने का सवाल है यह नामुमकिन है आप सोच रहे होंगे अचानक ऐसा क्या हुआ कि लैंडर अपने पथ से विचलित हो गया इसके पीछे तीन सम्भावना है किसी शत्रु देश द्वारा घुसपैठ आर्टिफिशियल इन्टेलीसेन्स द्वारा यान का स्वयं पथ परिवर्तन या चांद के दक्षिणी ध्रुव की संरचना
जो भी चांद पर फतेह की जा चुकी है आगे आगे देखिये होता है क्या❓




Is any human chandrayaan- 2

सवाल उठाने के लिए बहुत कुछ नहीं है परन्तु आप सभी को यह जानने का हक भी है कि चन्द्र यान में मानव हैं भी या नही इसका जबाब है नहीं क्यौंकि आरटिफिशियल इन्टेलीसेन्स के इस जमाने में मानव की तरह जब एक मशीन से काम हो सकता है तो मानव जीवन को खतरे में डालना तर्क संगत नही होता परन्तु दुर्भाग्य से यह मिशन एक अधूरेपन का अहसास दिलाता है वैसे यह एक अवसर भी है कुछ बेहतर करने का और पुनः स्थापित करने का आशा है शीघ्र ही हम एक कामयाब मिशन की ओर जाएगें

चन्द्र यान 2 के महत्वपूर्ण लक्ष्य है चन्द्रमा की सतह पर चन्द्रमा की मिट्टी का बैज्ञानिक विशलेषण तथा आबोहवा का परीक्षण करना है
इस मिशन के बाद में सिर्फ मिट्टी की जांच को छोड़कर शेष लक्ष्य प्राप्त हो गया है

India reveals Chandrayaan-2 Vikram moon lander crashed

India's Chandrayaan-2 Vikram lander crashed during an attempted moon landing, the nation has acknowledged. In a new report, the Indian government's Department of Space said the Vikram moon lander separated as planned on Sept. 2, but then braked too hard when it came to descending to the surface on Sept. 7.

"After two successful de-orbiting maneuvers, powered descent of the lander was initiated on 7th September 2019 to achieve soft landing on the moon surface," according to the report, which NPR reported earlier Wednesday and was in response to a lawmaker's inquiry last week.
The descent's first phase took the lander from 30km to 7.4km above the surface of the moon, with velocity reduced from 1,683m/s to 146m/s. But during the second phase of descent, "the reduction in velocity was more than the designed value."
"Due to this deviation, the initial conditions at the start of the fine braking phase were beyond the designed parameters," the government said. "As a result, Vikram hard landed within 500m of the designated landing site."
The Indian space department added all eight of the orbiter's scientific instruments are performing as planned, however, and it has increased its mission life to seven years.
Late last month, the lander was still missing despite NASA's search efforts. The Indian Space Research Organization had lost communication with the lander shortly before it was set to land on the moon. NASA's Lunar Reconnaissance Orbiter had scanned the expected landing since mid-September, but hadn't been able to spot the lander, which was meant to investigate the unexpected south pole of the moon.
"It is possible that Vikram is located in a shadow or outside of the search area.  Because of the low latitude, approximately 70 degrees south, the area is never completely free of shadows," NASA said in a statement last month.

Chandrayaan-2's Vikram hard landed within 500 metres of touchdown site, says govt.

Chandrayaan-2’s Vikram lander hard landed as reduction in velocity during its descent did not match with the designed parameters, the government said on Thursday, throwing more light on the ISRO’s dashed hopes of making a soft landing on the lunar surface in its maiden attempt.
In a written reply to a question in the Lok Sabha, Jitendra Singh, Minister of State in the Prime Minister’s Office who looks after the Department of Space, said the first phase of descent was performed nominally from an altitude of 30 km to 7.4 km above the moon’s surface and the velocity was reduced from 1,683 metres per second to 146 metres per second.
“During the second phase of descent, the reduction in velocity was more than the designed value. Due to this deviation, the initial conditions at the start of the fine-braking phase were beyond the designed parameters. As a result, Vikram hard landed within 500 metres of the designated landing site,” he said.
Mr. Singh, however, said most components of technology demonstration, including the launch, orbital critical manoeuvres, lander separation, de-boost and rough braking phase were successfully accomplished.
With regards to the scientific objectives, all the eight state-of-the-art scientific instruments of the orbiter were performing according to the design and providing valuable scientific data. Due to the precise launch and orbital manoeuvres, the mission life of the orbiter was increased to seven years, he said.
Data received from the orbiter was being provided continuously to the scientific community, he said, adding the same was recently reviewed in an all-India user meet organised in New Delhi.
The indigenously developed Chandrayaan-2 comprising the orbiter, the lander and a rover was successfully launched onboard the indigenous GSLV MK III-M1 Mission on July 22.
After accomplishing four earth-bound manoeuvres and trans-lunar injection, the spacecraft was successfully inserted into the lunar orbit on August 20. A series of moon-bound manoeuvres were then carried out to achieve a lunar orbit of 119 x 127 km.
Vikram was separated, as planned, from the orbiter on September 2, 2019. After two successful de-orbiting manoeuvres, a powered descent of the lander was initiated on September 7 to achieve soft landing on the Moon surface.
The ISRO is planning to launch Chandrayaan-3 probably in November next year.

India finally admits its Moon lander crashed two months after it was destroyed

India was poised to make history in September by becoming one of just a handful of nations to achieve a soft landing on the Moon. Everything was going smoothly… until it didn’t. Just moments before the Chandrayaan-2 lunar lander was supposed to touch down, its handlers back on Earth lost all contact with the spacecraft.
It wasn’t immediately clear what had happened to the lander, and the Indian Space Research Organization (ISRO) was hopeful that the spacecraft survived its impact. It tried to spot the lander on the surface but failed to detect it and, even after NASA’s own orbiter scanned the surface, the fate of Chanrayaan-2 remained unknown. Now, two months after the lander was presumed destroyed, ISRO is acknowledging that the spacecraft is gone forever.
As NPR reports, the Indian government has finally broken its silence on the death of the spacecraft, following questions from lawmakers who were eager to learn its fate.
“During the second phase of descent, the reduction in velocity was more than the designed value. Due to this deviation, the initial conditions at the start of the fine braking phase were beyond the designed parameters,” Jitendra Singh of India’s Department of Space, explains. “As a result, Vikram hard landed within 500 m of the designated landing site.”
The Chandrayaan-2 mission also saw the insertion of a lunar orbiter prior to the deployment of the lander. The orbiter has been performing well for ISRO, but obviously, the group would have liked to have accomplished the soft landing they set out to achieve. The team spent a significant amount of time trying to wake the spacecraft back up and resume communication even after it was thought to have crashed, but those attempts were met with only silence.
It’s clear that the lander couldn’t handle the conditions it was met with during landing and failed as a result. Whether this was due to a failure of the lander’s own systems or an anomaly in how the spacecraft reacted is unkno
