Here’s the schedule:

National Geographic Live: “Exploring the Red Planet” with NASA engineer Kobie Boykins at 7:30 p.m. Sunday and 10 a.m. Monday.

Few events in the last decade of space exploration have captured the world’s imagination like NASA’s ongoing Mars Exploration Program. Join Boykins for an engaging evening exploring the Red Planet, with an update on the very latest chapter in the ongoing story of Mars exploration.

National Geographic Live: “Passion 8000: Dream of a Lifetime” mountaineer Gerlinde Kaltenbrunner at 7:30 p.m. Feb. 21 and 10 a.m. Feb. 22.

Kaltenbrunner didn’t climb K2 because she wanted to be the world’s first woman to summit all 14 8,000-meter peaks without oxygen. But that’s exactly what she did. She grew up skiing in the mountains of her native Austria. Then working as a nurse, on weekends she would climb the local Alps. Her unstoppable appetite for adventure finally drove her to blaze a trail into the male domain of high altitude mountaineering. Share the dramatic story, told with breathtaking photos and video from the roof of the world, of how this mountaineer prepared for and triumphed on K2, earning Kaltenbrunner recognition as National Geographic’s “Explorer of the Year.”

National Geographic Live: “Coral Kingdoms and Empires of Ice” with photographer David Doubilet and aquatic biologist Jennifer Hayes at 8 p.m. April 8.

Discover Kimbe Bay, an unspoiled wilderness of water crowded with layers of life from fingernail-size pygmy seahorses to 60-foot-tall towers of barracudas. Then, journey south to the cold ice-filled waters of Antarctica, where the team moves through and under the ice to capture images of the hidden world of the leopard seal, penguins, shipwrecks, and the sculptural beauty of icebergs. Finally, follow the team north to Canada’s Gulf of St. Lawrence, an extraordinary world of whales, wolfish, salmon and harp seals.
