India’s moon mission Chandrayaan-2 launch delayed again
James Marshall | August 7, 2018

Скрытый текст

Chandrayaan-2 (Chandra: Moon / Yaan: Vehicle) India's second mission to the moon has been delayed until January 2019 because of technical glitches. As the weight of the Chandrayaan-2 spacecraft has increased, according to the source, GSLV Mk III or Isro's "fat boy", not GSLV Mk II, will now carry the spacecraft as it has the lifting capability of over four tonnes. A GSLV Mk III launch costs around Rs 4 billion and it also entails years of research and development.

Chandrayaan-2 Lander to be named ‘Vikram’ after Sarabhai

Chethan Kumar | TNN | Aug 12, 2018, 16:09 IST

BENGALURU: The lander on the Chandrayaan-2 mission, which is scheduled to be launched early next year, will be named ‘Vikram’ after Vikram Sarabhai, the father of Indian space programme. The Indian Space Research Organisation (Isro) has got clearance from the space commission, its chairman Sivan K said on Sunday.

This mission, unlike Chandrayaan-1 which only orbited the Moon, involves a Lander soft-landing on the lunar surface and unloading a Rover to study and take measurements from the Moon, while the orbiter will go around the Earth’s satellite.

“We’ve got the permission and this will be part of a series of things planned as part of the centenary celebrations of Vikram Sarabhai next year,” Sivan said, after unveiling Sarabhai’s bust at the Isro headquarters here.

Индия намерена проводить по два космических запуска ежемесячно

Космос | 13 августа, 9:33 дата обновления:13 августа, 9:50 UTC+3

НЬЮ-ДЕЛИ, 13 августа. /ТАСС/. Индийская организация космических исследований (ИСРО) планирует произвести в течение ближайших 16 месяцев 31 космический запуск, что составит примерно по две миссии ежемесячно, начиная с сентября. Об этом сообщил журналистам в Бангалоре глава ИСРО доктор Кайласавадиву Сиван.

....

Лунная миссия

Доктор Сиван сообщил прессе, что запуск к Луне автоматической станции "Чандраян-2" пока запланирован на январь 2019 года, но эта дата может измениться.

"Мы запланировали отправить миссию "Чандраян-2" 3 января. Мы определили эту дату и нацелены на нее. Но окно еще открыто. Мы можем еще отсрочить (запуск) и на март", - приводит в свою очередь слова главы ИСРО газета The Asian Age.

Причина отсрочки лунной экспедиции в том, что пришлось вносить важные изменения в конструкцию посадочного модуля, чтобы он мог легко сесть на поверхность Луны, что привело к увеличению массы всей станции, рассказал Сиван.

Первоначально планировалось, что индийская автоматическая станция отправится к Луне в апреле 2018 года. Но в марте было объявлено, что миссия переносится на октябрь, однако в начале августа ИСРО сообщила, что старт лунной экспедиции вновь отсрочен.

"Чандраян-2" продолжит индийскую лунную программу, которую начал аппарат "Чандраян-1", отправленный к спутнику Земли в 2008 году. Если "Чандраян-1" был орбитальной станцией, то "Чандраян-2" - гораздо более сложный проект, который предусматривает посадку на спутнике Земли и доставку на ее поверхность небольшого лунохода. До сих пор только США, Россия и Китай смогли осуществить мягкую посадку на поверхности Луны, напоминает издание.

Isro now looking at January 30 for Chandrayaan-2 launch
TNN | Oct 4, 2018, 08.14 PM IST



BENGALURU: January 30, and not January 3 as Isro had earlier indicated, will be the most optimal date for the launch of Chandrayaan-2, India’s second mission to the Moon.

The review committee had looked into three dates that were considered best in the January-to-March window available for the launch. “One could achieve a launch on any date during this window, but generally scientists study various prospects and pick a date that is the best,” one scientist explained.

TOI has reliably learnt that the committee looked at January 3, January 30, and February 14. After all deliberations, it was said: “January 30 will be a good option for Chandrayaan-2 launch since there is a 27 kg propellant advantage with respect to January 3 launch.”

Дата пуска индийской станции "Чандраян-2" к Луне еще не определена
НЬЮ-ДЕЛИ, 2 января. /ТАСС/. Индийская организация космических исследований (ISRO) сообщила, что предварительно анонсированный на 3 января старт индийской миссии "Чандраян-2" к Луне в этот день не состоится, точная дата старта будет объявлена позже. Как рассказал прессе глава ISRO доктор Кайласавадиву Сиван, она будет определена специалистами к середине января.
"Прямо сейчас я не могу назвать дату. Мы сможем принять решение по этому вопросу в течение 10-12 дней", - цитирует в среду Сивана новостной портал Firstpost.
Это уже не первая отсрочка старта автоматической лунной экспедиции. Первоначально планировалось, что индийская станция отправится к Луне в апреле 2018 года. Но в марте было объявлено, что миссия переносится на октябрь, однако в начале августа ISRO сообщила, что старт лунной экспедиции вновь переносится - предварительно на 3 января 2019 года. Затем ряд индийских СМИ называли дату 30 января, однако пока официального подтверждения она не получила.
Доктор Сиван добавил, что индийские специалисты делают все, чтобы аппарат отправился к спутнику Земли как можно скорее. Он не назвал причину отсрочки.
Первый индийский луноход
"Чандраян-2" продолжит индийскую лунную программу, которую начал аппарат "Чандраян-1", отправленный к спутнику Земли в 2008 году. Но "Чандраян-1" был орбитальной станцией, тогда как "Чандраян-2" - гораздо более сложный проект, который предусматривает мягкую посадку на спутник Земли и доставку на лунную поверхность небольшого лунохода.
Как ранее сообщала ISRO, спускаемый аппарат должен совершить прилунение в районе Южного полюса: пока еще никто не пытался серьезно исследовать этот район. Практически все миссии, организованные разными государствами в прошлом, исследовали в основном регион в районе лунного экватора.
Планируется, что небольшой самоходный аппарат, который будет получать энергию от солнечной батареи, будет работать по меньшей мере один лунный день (14 земных суток). По данным ISRO, общая стоимость проекта "Чандраян-2" составляет около $125 млн.

ISRO'S CHANDRAYAAN-2 MOON MISSION DELAYED A THIRD TIME, NEW LAUNCH DATE UNCLEAR

We will be able to decide on a launch date for Chandrayaan-2 in about 10 to 12 days: ISRO Chairman.

JAN 02, 2019 15:34 PM IST

The Indian Space Research Organisation (ISRO) has confirmed that the agency will not be launching Chandrayaan-2, its second lunar mission, on 3 January as announced earlier. For the time being, the agency doesn't have a confirmed date for launch.

With the many launches that were lined up in the second half of 2018, work on the moon mission was affected, reports The Times of India.

"At the moment, I cannot comment on the date. We will be able to decide on that in about 10 to 12 days," ISRO Chairman K Sivan said, according to the report.

This is the third delay that Chandrayaan-2's launch has seen since the project was announced – the first was in December 2016 and the second occured in October 2018.

ISRO is now scrambling to launch the mission at the earlier possible date in 2019, with the current window open from the first week of January to 16 February.

Chandrayaan-2, as well as China's ongoing Chang'e-4 moon mission, are aiming to achieve unique firsts in lunar exploration. At the time this story was written, the Chinese probe was positioned to land a lunar rover on the "far side" of the moon – the hemisphere that's always turned away from the Earth that has yet to be studied by a mission on the surface.

Chandrayaan-2, also a pioneering mission in its own right, is attempting to release its lander 'Vikram' on a previously unexplored region near the moon's South pole. Vikram and the rover on Chandrayaan-2 will touchdown at a site 600 kilometres from the lunar South pole.

If successful, the Chandrayaan-2 mission will be the first time a spacecraft lands so far from the lunar equator.

What is Chandrayaan-2 designed to study? What will it do once on the moon? Here's all the lunar science Chandrayaan-2 is aiming to work out.

Chandrayaan-2 not to blast off on Jan 3, Isro yet to fix launch datet
Chethan Kumar | TNN | Updated: Jan 1, 2019, 11:52 IST

BENGALURU: The Indian Space Research Organization (Isro) confirmed — as Chinese space probe Chang’e 4 on Sunday moved into position to land on the far, unexplored side of the Moon — that it would not launch its second lunar mission, Chandrayaan-2, on January 3 as announced earlier.

The space agency, which is scrambling to launch the mission in the first available window in 2019, does not have a launch date as yet.

Isro chairman Sivan K told TOI that the agency was busy with multiple launches in the second half of 2018 and this affected work on the moon mission. “At this moment I cannot comment on the date,” he said. “We will be able to decide on that in about 10 to 12 days.”

Both Chang’e 4 and Chandrayaan-2 will aim to achieve “firsts” on the lunar soil. While the Chinese probe will be the first to land on the far or ‘dark’ side of the Moon, the hemisphere that always faces away from Earth, the lander from Chandrayaan-2 will touch down in an unexplored area near the lunar South Pole.

Xinhua news agency reported that Chang’e 4 had entered a planned orbit on Sunday to prepare for the first-ever soft landing on the far side of the moon, but did not specify when the landing would take place.

Isro is preparing to launch Chandrayaan-2, which missed two planned launch windows in 2017 and 2018, in a window from the first week of January to February 16.

ISRO Says Chandrayaan-2 Moon Mission Launch Planned for Mid-April
Press Trust of India, 11 January 2019

The launch of India's second Moon mission, Chandrayaan-2, is planned for the middle of April this year, Indian Space Research Organisation (ISRO) chairman K Sivan announced Friday.

ISRO had earlier said Chandrayaan-2 will be launched in a window between January-February 16 this year. The mission, costing nearly Rs. 800 crores, is an advanced version of the previous Chandrayaan-1 mission about 10 years ago. "Regarding Chandrayaan-2 schedule, right now Chandrayaan is scheduled from March 25 to April end. Most probably, the normal targeted date is April middle," Sivan told reporters in Bengaluru.

He said the space agency had earlier planned to launch the spacecraft sometime between January and February but it could not materialise because certain tests could not be conducted. "Once we missed the February target, next available target is April. Right now it is planned for April," the ISRO chief added.

ISRO likely to postpone Chandrayaan-2 launch as scientists scramble to meet revised deadline

There were reports earlier that ISRO’s second moon lander, titled ‘Vikram’, had suffered damage during preliminary tests ahead of the original plan for an April launch.

THIRUVANANTHAPURAM: Chandrayaan-2, the second mission of the Indian Space Research Organisation (ISRO) to the moon, is likely to be delayed further and, in all likelihood, will be held in July.

ISRO officers are reportedly working to meet the revised target of July to launch Chandrayaan- 2 with a lander and rover.

However, ISRO chairman K Sivan refused to acknowledge the new date se t by ISRO, saying that making any statement regarding the project would constitute to a violation of the Model Code of Conduct which is in force in view of the Lok Sabha elections.

There were reports earlier that ISRO’s second moon lander – titled ‘Vikram’ as a tribute to the pioneer of India’s space programme and former ISRO chairman Vikram Sarabhai – had suffered damage during preliminary tests ahead of the original plan for an April launch.

However, officers close to ISRO said this happened some time back and the issues were all solved.

Earlier, ISRO had announced the lunar mission with a lander and rover will be attempted in January- February window. It was later revised to March-April window.

Now, ISRO is bracing itself to conduct the mission in July as the June-July window is ideal for the same with July being more suitable for landing on the lunar surface, said a senior officer

PRESS RELEASE ON CHANDRAYAAN-2



Chandrayaan-2, India’s second lunar mission, has three modules namely Orbiter, Lander (Vikram) & Rover (Pragyan). The Orbiter and Lander modules will be interfaced mechanically and stacked together as an integrated module and accommodated inside the GSLV MK-III launch vehicle. The Rover is housed inside the Lander. After launch into earth bound orbit by GSLV MK-III, the integrated module will reach Moon orbit using Orbiter propulsion module. Subsequently, Lander will separate from the Orbiter and soft land at the predetermined site close to lunar South Pole. Further, the Rover will roll out for carrying out scientific experiments on the lunar surface. Instruments are also mounted on Lander and Orbiter for carrying out scientific experiments.

All the modules are getting ready for Chandrayaan-2 launch during the window of July 09, to July 16, 2019, with an expected Moon landing on September 06, 2019.

Chandrayaan-2: With 2 months to go, only orbiter is mission ready so far

Chethan Kumar | TNN | Updated: May 5, 2019, 20:09 IST

BENGALURU: The Indian Space Research Organisation (Isro) on Wednesday announced it is looking to launch Chandrayaan-2 between July 9 and July 16, with the Moon landing expected in September. However, with just about 60 days left for the proposed launch date, only one of the three key modules of Chandrayaan-2, India’s second lunar mission, is ready.

Sources in Isro said that of the three crucial modules of the mission — the Orbiter, Lander and Rover — only the Orbiter (the satellite) is mission ready, with several tests still keeping the other two on test beds.

It is noteworthy that the Lander (Vikram) and the Rover (Pragyan) are modules Isro has no past experience in making, while it has already built and operated a satellite to go around the Moon as part of Chandrayaan-1.

“The orbiter has attained MOR (mission operation readiness) status, the rover and lander haven’t gone so far yet. The instruments on Pragyan, including the camera, are being tested at the Lunar Terrain Test Facility (LTTF) at the Isro Spacecraft Integration Test Establishment (Isite). Data fr om these instruments is being collected. For instance, we are taking images from the camera and making models,” the source said.

While Pragyan too has seen a smooth transition from the design on paper to the actual module, Vikram has been a concern for Isro with the design changed multiple times. Among several hiccups faced by Vikram, its qualification model, as reported by TOI in April, had suffered some damages during an earlier drop test.

“The review and redesign is now complete, which means that several new tests will now have to been done,” the source said. Isro chairman Sivan K had earlier said that the damage during the drop test was caused because of wrong configuration and orientation of the test.

Key Lander Test

With the review and redesign now complete, the space agency has moved the qualification model of Vikram to Byalalu, wh ere it owns huge land as part of the Isro Telemetry, Tracking and Command Network (Istrac).

“We will conduct the Landing Terminal Detailed Test (LTDT), which is likely to begin Monday and go on for at least a week,” the source said.

The TOI has learnt that Vikram will be tested at a height of only a few metres, to check for hovering and horizontal movement. “There may finally even be a touchdown test, but that will depend on the ground condition. The initial tests will see the lander hanging by a construction crane with the engine turned on. We will be measuring the velocity and the force,” the source said.

Sivan, while confirming that the lander will be tested, said: “There is a lot of curiosity about this mission and we will give out more details in the first week of June. We are also going to show Chandrayaan to the people through you (media).”
