The 3300kg shipment launched on Thursday (local time) which also includes fresh lemons, onions, avocados and cherry tomatoes for the stations seven astronauts should arrive Saturday.
SpaceXs Falcon rocket blasted into the hazy afternoon sky from Kennedy Space Centre. The first-stage booster was new for a change, landing on an offshore platform several minutes after liftoff, so it can be recycled for a Nasa astronaut flight this autumn (NZ spring).
Cargo on the Dragon 2 spacecraft includes samples of saliva and oral bacteria from dental patients that will be treated with toothpaste and mouthwash in an experiment aimed at keeping astronauts mouths healthy in space.
The Dragon cargo capsule also brand new is delivering the first of three sets of high-tech solar panels designed to bolster the space stations ageing power grid. Astronauts will conduct two spacewalks later this month to help instal the two roll-out panels alongside solar wings that have been in continuous operation for 20 years.

More power will be needed to accommodate the growing number of ticket-buying visitors, Nasas space station program manager, Joel Montalbano, said Wednesday.

Theres no guarantee that the Earth methods will work in zero gravity, researcher Jeffrey Ebersole of the University of Nevada Las Vegas said in a statement.
Also headed to the orbiting lab: 20,000 tardigrades, better known as water bears, and 128 bobtail squid, as well as chilli pepper plants and cotton seedlings.

Tardigrades can survive in drastic environments on Earth and even in the vacuum of space. Launched frozen, these microscopic extremophiles will be thawed and revived aboard the space station. By identifying the genes behind the animals adaptability, scientists hope to better understand the stresses on the human body during long space stays.
The baby bobtail squid are part of a study investigating the relationship between beneficial bacteria and their animal hosts.
This is SpaceXs 22nd station supply run for Nasa. The space agency turned to private companies to transport cargo and astronauts following the shuttles retirement a decade ago.
