It is all about Chandrayaan 2, and in a little more than two hours from now, India's Vikram probe carrying a small rover called the Pragyaan will carry out a risky and extremely difficult manoeuvre to soft land near the south pole of the Moon. By about 2:10 am, we will know if Vikram has touched down on the moon safely. There may be video and pictures as well. The next big event will be after 3:40 am when the Pragyaan rover rolls out onto the surface of the Moon.
