Past Canadian Experiments on the Station

Advanced Plant Experiments on orbit (APEX-Cambium)

Canada's first study of its kind, APEX-Cambium helped to determine the role gravity plays in how trees form different kinds of wood.

See APEX-Cambium section

Advanced Plant Experiments on Orbit (APEX-CSA2)

Canadian white spruce seedlings were sent to the Space Station to help researchers understand how trees make wood.

Colloids. From the paint on your walls to your salad dressing, colloids are commonplace. But why do we study them in space?

See BCAT-C1 section

Bodies In the Space Environment (BISE) - Which way is up in space?

An experiment that studied how astronauts distinguish up from down in a near-weightless environment.

See BISE section

Predicting fainting in astronauts (BP Reg)

Monitor astronauts' blood pressure to predict the risk of fainting (and taking a possibly crippling fall) back on Earth after long-duration spaceflights.

See BP Reg section

CCISS: Heart-pounding results from Canadian cardiovascular experiment

This experiment studied how long periods in space affect the human body. It also offers approaches that will better protect space travelers in the future.

See CCISS section

Little transistor records radiation levels (EVARM)

An experiment that enabled researchers to measure the levels of radiation astronauts are exposed to during a spacewalk.

See EVARM section

H-Reflex flexes its muscles!

H-reflex was the first medical experiment completed on the Space Station to study how the human body adapts to weightlessness. So how does zero gravity affect an astronaut's body?

See H-Reflex section

The Ultimate Tickle Test (HYPERSOLE)

A Canadian research project that studied sudden changes in skin sensitivity experienced by some astronauts.

See HYPERSOLE section

Marangoni Experiment in Space (MEIS-2)

The results from the Marangoni experiments on the ISS could be used to develop higher quality, more efficiently produced semiconductor crystals.

See MEIS-2 section

Diagnosing Medical Conditions on Earth and in Space (Microflow)

The portable, technology could offer near real-time medical diagnosis for astronauts in space, people in remote communities or in areas affected by natural disasters where medical equipment is not readily available.

See Microflow section

Perceptual Motor Deficits in Space (PMDIS)

The study found that astronauts' bodies must be restrained while performing fine motor movements but arm restraints are not necessary.

See PMDIS section


To properly learn about how thermal diffusion works, it is necessary to isolate it so that it is the only thing affecting molecular movement in a liquid—gravity must be removed. SODI-IVIDIL does just that.

See SODI-IVIDIL section

Vascular: Cardiovascular health in space

Vascular discovered that astronauts returned from six months on the ISS with increased arterial stiffness equivalent to aging 10 to 20 years.
