Episode 11: Digging In: When Rovers Get Dirt on Mars
Apollo 15 astronauts conducted the first deep-drilling operation on the Moon in 1971. The Apollo 15 mission’s Lunar Surface Drill was designed to carve out a core of rock up to 10 feet, or 3 meters down. The battery-powered drill worked well until astronauts Dave Scott and Jim Irwin tried to pull their rock core out.
Episode 9: Before You Can Drive, First You Have to Fly
JPL engineer honed entry, descent and landing procedure for NASA's Mars rovers. Curiosity and Perseverance had a little bit of lift to allow us to control how far the vehicle is going to fly downrange. The rover’s capsule has built up a lot of speed after its launch off Earth and many-months journey.
Episode 8: How to Drive a Mars Rover
Vandi Verma is the chief engineer of Mars Perseverance robotic operations. She's been driving rovers on Mars with Curiosity and now Perseverance. A Mars drive starts on Earth, with a team of scientists and engineers developing a list of actions they want the rover to take.
Episode 7: Flying with Ingenuity: the Mars Helicopter
NASA's Ingenuity helicopter made the first powered, controlled aircraft flight on Mars. Ingenuity hitched a ride with NASA’s Mars 2020 mission, which sent the Perseverance rover to collect rock samples. A postage-stamp-sized bit of muslin fabric had once covered a wing of the Wright Brothers’ 1903 aircraft.
Episode 6: The Promise of Perseverance
NASA's latest Mars rover is a step toward realizing the Mars Sample Return goal of the past fifty years. The Mars 2020 mission is especially targeting often-fragile sedimentary layers, like those laid down in lakes and river deltas. On Earth, life is abundant and signs of ancient life tend to be well-preserved.
Episode 5: A Ton of Curiosity
The Mars rover Curiosity is a six-wheeled vehicle that weighs nearly a ton. The rover also has a kind of mouth, nose, throat, and stomach. These allow Curiosity to take Mars into itself, breathing in the air and eating the rocks and soil. Curiosity has chewed on the question of what the planet Mars is made of.
Episode 4: A Lifetime on Mars: The Adventures of Spirit and Opportunity
This is the fourth episode of the “On a Mission to Mars” podcast. This week, we look at the landing instructions for NASA’s Spirit and Opportunity rovers on Mars. We also look at the legacy that these rovers gave us on Earth.
