The scientists aboard the International Space Station are about to get a serious jolt of caffeine, courtesy of Elon Musk.

SpaceX, the aerospace company Musk runs alongside electric car company Tesla, is set to launch a resupply mission to the ISS that will include an espresso machine, The Oregonian reports. The espresso maker is meant specifically for an Italian astronaut on board, and it is designed to operate safely in zero-gravity.

The SpaceX launch was attempted Monday afternoon, but scrubbed due to weather. It has been rescheduled for Tuesday at 4:10 p.m. ET.

After the mission launches, SpaceX will try to vertically land the rocket’s first stage on a floating barge waiting for it about 200 miles off the Florida coast. The attempt will mark SpaceX’s latest in an effort to make it easier and cheaper to reuse space rockets.

Unlike Tesla, SpaceX is a private company, though IPO rumors have swirled in the past.
