UN Convention to Combat Desertification meeting nears conclusion in Greater Noida. What is causing desertification of land around the world, and what role does the Convention play in trying to combat it?

Explained: How ISRO is trying to reconnect with Vikram Lander, within a deadline

ISRO's Chandrayaan-2 Moon landing mission: The nights on the Moon can be very cold, especially in the south polar region where Vikram is lying. Temperatures could drop to as low as -200°C. The instruments aboard the lander are not designed to withstand that kind of temperature.

Explained: Chandrayaan-2, in perspective

Vikram’s failure to land may have caused disappointment, but much of the Chandrayaan-2 mission remains on track. A reminder of the tasks of the orbiter, which remains functional, and some ideas on what might have happened to the lander.

ISRO hope: No news not necessarily bad news

ISRO issued a statement Saturday to emphasise that the Chandrayaan-2 mission was still on, and had a lot of science left in it, despite the setback. The statement threw no light on what could have happened to the lander, except for saying that communication with it had been lost.

Chandrayaan 2: Vikram lander’s failure raises questions on manned mission

ISRO also has several other high-profile missions lined up for the next few years, including a mission to the Sun, a mission to Venus, and a stated plan to set up a permanent space station.

Final five mins of Chandrayaan-2 and the heartbreak hours: Watching hope crash in mission control

Chandrayaan-2: Vikram was on its way to land on the Moon as per plan. The bulk of the deceleration had already been achieved, and the next phase of the descent, during which the velocity was supposed to be brought down to about 2 metres/sec, was expected to be smoother.

Explained: ISRO’s Vikram Lander is lost, but this hardly matters. Here’s why

The maximum amount of science in ISRO's Chandrayaan-2 mission is supposed to be done by the instruments onboard the Orbiter which is in perfect health and communicating with the ground station.

Chandrayaan 2: Two km from Moon, Vikram lander loses contact with mission control

Chandrayaan 2 status: The mission operations complex at the ISRO Telemetry, Tracking and Command Network in Bengaluru stopped receiving data from the lander. ISRO chief K Sivan said communication with the lander had been lost.

Explained: Chandrayaan-2 and the quest for water on moon

The clinching evidence of presence of water on moon was provided by two instruments on board Chandrayaan-1. It has totally changed the way scientists now view the moon, and has led to a renewed interest in lunar exploration.

Explained: Chandrayaan-2 was to be launched by India and Russia in 2011; it’s delayed but better

Chandrayaan-2 Moon landing: In fact, Chandrayaan-2 was conceived well before the launch, and success, of Chandrayaan-1.

Explained: Why Chandrayaan-2 will land near the south pole of the Moon

Chandrayaan-2 Moon landing: The furthest that any spacecraft has gone from the equator was Surveyor 7, launched by NASA, that made a moon landing way back on January 10, 1968. This spacecraft landed near 40 degree south latitude.

Explained: As Chandrayaan-2 makes Moon landing, here’s what you’ll see

Chandrayaan-2 Moon landing: For a few hours after the landing there would be a state of a near complete blackout and no images would be sent. That is because the landing would cause a lot of dust on lunar surface to rise.

Explained: Chandrayaan-2 is 110th Moon mission, these are the previous lunar missions

Missions to moon slowly resumed in the 1990s but have picked up steam only in the last decade. The discovery of the presence of water on the moon, by Chandrayaan-1 mission in 2008, has been one of the prime reasons for a renewed interest in moon.

Chandrayaan-2 highlights: ISRO issues latest update, says 95% of mission objectives accomplished

Chandrayaan-2 Moon Landing Highlights: "Our determination to touch moon has become even stronger, we came very close but we need to cover more grounds," PM Modi told ISRO scientists.

Chandrayaan-2 landing: 15 ‘terrifying’ minutes to history tonight

Chandrayaan-2: If successful, this would be India’s first soft landing on the moon’s surface. Only the US, the former USSR and China have been successful in landing humans or machines on the moon surface.

Explained: Mapping lightning across India

For the first time, a report has mapped lightning strikes across the country, and the lives they have claimed. What are the findings, and how can these be used to prevent damage in the future?

Lander bids goodbye to Chandrayaan-2 in countdown to descent

The Vikram lander, which carries the Pragyan rover module inside it, is currently moving in the same orbit as the main spacecraft which had descended to a near-circular orbit Sunday. This orbit is 119 km from the moon’s surface at its nearest and 127 km at the farthest.

Explained: How do governments set climate targets?

In their recent joint declaration, India and France have committed to making long-term plans to contain emissions. While most countries set targets against a deadline, there is a case for longer-term planning
