India's Chandrayaan-3 mission has missed a key check-in following a long and cold lunar night that the ISRO hoped it would reawaken after.
Both spacecraft had solar panels pointed toward the Sun, and the ISRO was hopeful that the two would reawaken when the lunar night passed and the Sun once more rose over the Lunar South Pole. However, according to a tweet from the ISRO, the Chandrayaan-3 mission has missed this important check-in, and no signal has been received from either the rover or the lander.“Efforts have been made to establish communication with the Vikram lander and Pragyan rover to ascertain their wake-up condition,”.
Now, there are a couple of possibilities here for why Chandrayaan-3 missed its check-in. While it’s possible that both the Vikram lander and the Pragyan rover have not survived the harsh, cold Lunar night, it’s also likely that the sheer cold drained the batteries onboard the two spacecraft, and they now require recharging via the solar panels installed on them.
Unfortunately, it’s too early to tell precisely what the issue might be. This wouldn’t be the first time a spacecraft didn’t survive a cold night on another cosmic body, though. Previously,

Looming strike by miners raises worry about India Coal suppliesThe world’s biggest coal producer, state-owned Coal India, is facing a potential three-day strike across its core and subsidiary units, according to a stock exchange filing, prompting fears of supply disruptions across the country. The mining giant said it wrote to India’s Chief Labour Commissioner asking to take necessary action to maintain uninterrupted coal supply, stressing that the industry is a “Public Utility Service”. Coal India’s average daily production is nearly two-million tons, which includes both coking and non coking coal. The fuel provides around 70% of India’s electricity needs.
