Today India attempted to become only the fourth nation to successfully soft-land on the surface of the Moon. That mission appears to have failed, when the Indian Space Research Organisation (ISRO) lost contact with its Vikram lander at an altitude of 2.1km above the lunar surface. The space agency has said only that it is analyzing available data, and that the Chandrayaan-2 spacecraft is still in orbit. Indian prime minister Narendra Modi is scheduled to address the nation at about 10:30 ET.

If the mission is lost, then out of three soft-landing attempts this year it will be the second to go awry. China's Chang'e 4 reached the far side of the Moon in January, while the privately-owned Beresheet lander from Israel crashed in April after sending back one last photograph.
