SpaceX will have to wait another day to deliver groceries to the International Space Station.

Fast-approaching storm clouds prevented the unmanned rocket from blasting off Monday from Cape Canaveral, Florida. The company will try again Tuesday. But more bad weather is forecast.

The countdown was halted at the 2 1/2-minute mark.

The SpaceX supply ship holds more than 1,800 kilograms of food, experiments and equipment, including an espresso maker. Italy provided the specially designed espresso machine for Italian astronaut Samantha Cristoforetti.

Once the cargo ship flies, SpaceX will try to land the leftover booster on an ocean barge. It will be the third such landing attempt for the California company led by billionaire Elon Musk. SpaceX aims to reuse the first-stage boosters that are normally thrown away, to make spaceflight more affordable.
