India, June 30 -- S paceX founder Elon Musk marked his 55th birthday on Sunday with a celebration that reflected his long-standing fascination with space, complete with a rocket and Moon base-themed cakes. His mother, model-dietician Maye Musk, shared glimpses of the celebration on X. The highlight was a cake modelled after SpaceX's Starship rocket. Designed in silver, black and white, it lay on a launch-pad base. Musk was seen leaning over it to blow out candles placed at the base, creating the visual effect of ignition just before lift-off. The second cake recreated a miniature Moon base, featuring a cratered lunar surface with tiny astronaut figurines, a spacecraft, rovers and space stations. Alongside the pictures, Maye wrote, "Happy birthday to my wonderful son. @elonmusk has given me 55 years of joy." HTC...
