TGR & Friends ski film festival premiers Teton Gravity Research's annual epic ski film and invites their Scandinavian ski friends to show their short films to kick-off the evening. This year's short films are produced by Nikolai Schirmer, Jacob Wester, and Norrøna athlete Emil Leenderts.

Actually, It Is Rocket Science is the newest chapter in TGR’s ongoing study of the fall line, told through the world’s best skiers as they turn the mountain into a laboratory and every descent into an experiment.

The study spans Bute Inlet, British Columbia; Haines, Alaska; Japan; Finland; Andorra; Montana; Jay Peak, Vermont; and Jackson Hole, Wyoming. Different mountains, snowpacks, conditions, and approaches—but the same forces are always at work: speed, gravity, instinct, and consequence.

Actually, It Is Rocket Science is a tongue-in-cheek look at the seemingly reckless abandon that many of the world's best snow athletes display as they push the physics of what is possible. Athletes explore the intricacies of dissecting a big mountain line, the physics and amplitude of a massive gap, calculating transition, and the force of gravity.

So, is it rocket science—or is it not?

Watch closely and decide for yourself.
