A molecular biologist turned astronaut is due to decode DNA in space.

Kate Rubins, who studied Ebola and other deadly viruses before becoming an astronaut, will use a pocket-sized device to decode DNA in space.

As the first professional virus-hunter in space, she will attempt to complete the first full-blown DNA decoding, or “sequencing,” in orbit.

She will be working with harmless test samples.

The device will be delivered to the International Space Station on the next SpaceX delivery. Liftoff is scheduled for Monday from Cape Canaveral, Florida.

In an interview with The Associated Press on Wednesday, Rubins said the benefits of DNA sequencing in space are huge, and it could also prove useful in remote locations on Earth.
