The Advanced Plant Experiments on Orbit (APEX-CSA2) white spruce seedlings have sprouted some new shoots! This time-lapse video shows a close-up of the trees in their incubator on board the International Space Station over a six-day period. The new growth appears as light-green and orange buds that unfurl into fresh needles towards the end of the video. The seedlings will continue to grow in space until early May, when they will be harvested for their return to Earth on board Space Shuttle mission STS-132.

Does visual perception change in the weightless environment? The graduate students of the International Space University believe it does, so they have created the IRIS (Image Reversal in Space) experiment for Canadian astronaut Bob Thirsk to take part in.

Canadian Astronaut Bob Thirsk is a test-subject for the ground-breaking Canadian experiment BISE (Bodies in the Space Environment), which examines how humans distinguish up from down in weightlessness.
