ISRO Chandrayaan-2 launch LIVE UPDATES: Countdown for India's mission to the moon begins; lift-off at 2.43 pm

Chandrayaan-2 Moon Mission Launch Live Updates: A week after the Chandrayaan-2 mission was aborted, India will at 2.43 pm Monday make a second attempt at launching its first exploratory mission to the Moon. Scientists of the Indian Space Research Organisation (ISRO) will have a window of only a few minutes to launch Chandrayaan-2, making it necessary that all operations in the run-up to lift-off are conducted with extreme precision.

About 15 minutes after take-off, the 43-metre tall rocket, named ‘Baahubali’, will inject the spacecraft into the Earth’s orbit. Chandrayaan-2 will spend 23 days in Earth’s orbit, where it will undergo 15 crucial manoeuvres. The journey to the Moon is expected to take around seven days, before it spends 13 days in lunar orbit. In the first week on September, a module of the spacecraft is expected to land on the Moon.

Chandrayaan-2 launch shortly: ISRO preps for 2.43 pm lift-off

We have less than an hour now for the launch of Chandrayaan-2 from Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh. The filling of Liquid Oxygen in cryogenic stage(C25) of GSLV MkIII-M1 has been completed.



Chandrayaan-2: What is this ‘launch window’ that ISRO is targeting?

The window of opportunity for the launch of India’s first lander mission to the Moon is extremely small — barely a few minutes — and the scientists have very little flexibility in the final minutes before lift-off. Why is this? Since everything in space is in motion, and because there are no straight lines in space flight, a successful launch is a matter of detailed and complex mathematical calculations.

Dark side of the Moon: Chandrayaan-2 is heading for the Moon's south side

Chandrayaan-2, which means 'moon-craft' in Sanskrit, is heading for the south side of the Moon. This is a site where no mission has gone before. This is the part of the Moon which holds the possibility of presence of water. So far, Moon landings have been in areas close to its equator as it receives more sunlight, which is required for solar-powered instruments. If Chandrayaan-2 becomes successful, India will become only the fourth nation to land a rover on the lunar surface after the US, Russia, and China.

Launch of Chandrayaan-2: Three hours to go!

There is just under three hours to go for the launch of Chandrayaan-2, India's mission to the Moon. In case you're just joining us, ISRO second Moon shot is scheduled for 2.43 pm this afternoon. Stay with us as we bring you the latest news and updates!

Chandrayaan-2: Here’s what APJ Abdul Kalam said on India’s lunar mission

Former President A P J Abdul Kalam, a former aerospace scientist who was widely known as the ‘Missile Man of India’, had given suggestions to the Indian Space Research Organisation (ISRO) and NASA scientists on Chandrayaan-2 nearly 10 years ago.

Chandrayaan-2: Surviving days and nights on the moon

The moon has extremes of both hot and cold temperatures. Near the its equator, daytime temperatures reach 120 degrees Celsius, while at night it is about -130 degrees Celsius. So, how do missions survive the lunar night? Virat Markandeya explains.

Why the world’s in a second race to the moon

It is now 50 years from the first landing on July 20, 1969, that humans have finally decided to go back to the moon. The stage is now set again for a race to the moon over the next decade, and, this time, it is likely to be markedly different from the earlier one. In all probability, it will involve multiple participants, be more collaborative than competitive, and will be guided by the overall objective of utilising the resources of the moon, setting up permanent facilities for scientific explorations and using it as a launch pad to take humans deeper into space,

Chandrayaan-2 launch today: A timeline

Here's a quick timeline of dates of ISRO's Rs 100 crore Chandrayaan-2 moon mission:

* 23 days in Earth's orbit
* Seven days to journey to the Moon
* 13 days in lunar orbit
* Lander module to separate from Orbiter on Day 43, or September 2
* September 6: Landing on the Moon

Chandrayaan-2 — Orbiter, Lander and Rover

Chandrayaan-2 is a moon-lander and rover mission. The spacecraft, which will orbit the Moon from 100 kilometres away, is also carrying a Lander and Rover. The Lander will carry the Rover to the surface of the Moon. The Rover will crawl on the surface, at one centimetre per second — eventually to 500 metres — to collect and transmit data back to Earth. Powered by solar panels, both will have an expected mission life of about 14 earth days, by which time the experiments are expected to be terminated.



Chandrayaan-1: What did India's first moon mission accomplish?

Chandrayaan-2, which will be launched today, is an extension of Chandrayaan-1, India's first mission to the moon. It operated for nearly a year between October 2008 and August 2009. During this time, the orbiter helped discover evidence of water molecules on the Moon. Chandrayaan-2 will attempt to investigate the presence of water, as well as fossil footprints, on the Moons which could hold the answers to the origins of the earth and solar system.

 EXPLAINED: Why Chandrayaan-2 was aborted last week

Due to a sudden drop in pressure in one of the tanks containing helium gas on the GSLV Mk-III rocket, ISRO decided to abort the Chandrayaan-2 moon mission on July 15. The rocket, which will be launched today, will deliver Chandrayaan-2 in Earth's orbit. This spacecraft consists of three modules — Orbiter, Lander and Rover.


Narrow window for ISRO for launch of Chandrayaan-2 today

Scientists from ISRO have a small window of opportunity to launch Chandrayaan-2 this afternoon. After the mission was deferred on July 15, the next most suitable time was for "barely a couple of minutes" this afternoon. "So, all operations in the run-up to the launch have to be completed with extreme precision. There is no room for any delay,” a former ISRO scientist said.

 Chandrayaan-2 launches today at 2.43 pm; stay tuned!

Welcome to our live blog on the launch of Chandrayaan-2, ISRO's mission to the Moon. A 20-hour countdown is underway for lift-off, which is scheduled at 2.34 pm. Follow our live blog through the day for the latest news and updates.

SRO Chandrayaan-2 Launch Live Updates:
Chandrayaan-2 will spend 23 days in the Earth’s orbit, after which its journey to the Moon will take seven days. For the next 13 days, it will remain in lunar orbit, going around the Moon in an orbit of 100 km. The Lander module would separate from the Orbiter on Day 43, or September 2, and could continue to go around the Moon for another few days in a lower orbit.

The actual landing will happen on September 6, as originally scheduled, or in the early hours of September 7.

Chandrayaan-2 is India’s first attempt to land on the lunar surface. Its first Moon mission Chandrayaan-1, which was launched in 2008, was an Orbiter mission. But one of the instruments on board, called Moon Impact Probe (MIP) was made to crashland on the lunar surface. The MIP was one of the two instruments of Chandrayaan-1 that provided irrefutable evidence of the presence of water on the Moon.
