Ever wonder how astronauts know which way is “up” in the vastness of space? In our latest Spacecraft Guide episode, we’re diving into the NASA Boeing Starliner’s PDI (Primary Flight Display) and its remarkable NASA Boeing Starliner’s ADI (or Attitude Directional Indicator) – the modern-day answer to the iconic Apollo “eight-ball”! 🌌

Explore the NASA Boeing Starliner’s ADI and Control Panel

Our VR museum allows you to explore the Starliner’s control panel like never before. Join us as we break down each piece of technology that helps astronauts navigate in zero gravity. From gyroscopes to electronic displays, get a closer look at how the Starliner brings together decades of spaceflight innovation. ✨

The NASA Boeing Starliner’s ADI, or Attitude Directional Indicator, is a crucial instrument used in aircraft and spacecraft to help pilots and astronauts understand their orientation relative to the horizon. In a spacecraft, especially when navigating the vast emptiness of space without an up or down, this instrument becomes essential to ensure accurate positioning, stability, and navigation. Here’s a breakdown of how it functions and its importance:

NASA Boeing Starliner’s ADI Basic Functionality

The NASA Boeing Starliner’s ADI shows the “attitude” or orientation of the spacecraft around three axes:

• Pitch: The up-and-down tilt of the spacecraft’s nose.
• Roll: The rotation around the spacecraft’s longitudinal axis.
• Yaw: The left and right direction of the nose relative to the path.

These orientations are essential for maneuvering and positioning, whether for re-entry, docking, or aligning the spacecraft with specific celestial objects or paths.

Three Degrees of Freedom

The ADI can display three degrees of freedom using an internal gyroscope and electronic displays. Each of the three axes (X, Y, and Z) is tracked by sensors, which relay this data to the display, creating a real-time visual representation of the spacecraft’s orientation. This is especially critical in spacecraft like the Boeing Starliner, where crew members rely on precise control of attitude to complete complex missions.

Electronic “Eight-Ball”

In earlier spacecraft like Apollo and Gemini, astronauts used a physical “eight-ball” indicator to understand attitude, but modern spacecraft use electronic displays to represent this information. This digital version on the Starliner is far more advanced, offering more detail and real-time updates, and it’s integrated into the spacecraft’s flight systems to work with other indicators, such as speed, altitude, and trajectory.

Discover the Iconic Moon Boulder That Helped Shape Our Understanding of the Moon’s Origins

The Apollo 17 mission is etched in history, not only as the last mission to land humans on the Moon but also for the groundbreaking discoveries it made about the Moon’s origins. One of the most iconic images of this mission is of astronaut Jack Schmitt standing beside the Iconic Moon Boulder—yet this rock holds a story that has shaped our understanding of how the Moon was formed.

In this blog post, we’ll take you on a fascinating journey to explore this historic lunar rock, why it’s significant, and what it tells us about the Moon’s volcanic past. If you’re a space enthusiast, buckle up—you won’t want to miss this.

The Iconic Moon Boulder That Changed the Game

During the Apollo 17 mission, Jack Schmitt and Gene Cernan collected samples from a rock that showed some unique characteristics. This rock, called anorthosite, was formed billions of years ago when a massive collision between Earth and a Mars-sized body created the Moon. The Moon, essentially a chunk of the Earth’s mantle, cooled over millions of years, and this rock crystallized, floating to the Moon’s surface.

This discovery helped solidify the theory that the Moon was formed from a giant impact—a theory that has since become widely accepted in the scientific community. The rock collected by Schmitt provided physical evidence for this, showing that the Moon’s surface was once covered by a sea of lava, allowing these specific crystals to form.

Why This Matters to Space Exploration

Studying this lunar rock helps us understand not just the Moon, but also Earth’s early history. The same processes that occurred on the Moon also happened on Earth, making it a critical clue in piecing together how planets evolve. It’s one thing to study volcanic rocks here on Earth, but examining them on the Moon—where there’s no longer any volcanic activity—opens a unique window into a time billions of years ago.

And guess what? You can experience this journey in a whole new way.

Take a Virtual Tour of Apollo 17’s Lunar Findings

We’re excited to offer you a fully interactive virtual reality experience where you can explore the Apollo 17 mission’s landing site. Imagine standing right where Jack Schmitt collected this historic sample! You’ll get up close with the lunar module, the tools astronauts used, and even the rock itself.

Spacecraft Guide: Unveiling the Secrets of the Moon’s Composition Through the Passive Seismic Experiment Package

Are you fascinated by the Moon’s mysteries and the thrilling discoveries made by spacecraft? Then you’re in for an astronomical treat! The surface of the Moon holds fascinating clues about its composition and structure, and NASA has used some pretty dramatic methods to uncover them — crashing spacecraft into it!

In this edition of Spacecraft Guide, we’ll explore the surprising scientific tools that revealed what lies beneath the Moon’s surface. Forget about those hollow moon conspiracies, and instead, let’s dive into the incredible seismic experiments conducted during the Apollo missions. Spoiler: It involves deliberate spacecraft crashes!

Seismic Experiments on the Moon

Back in the Apollo days, astronauts and NASA scientists weren’t just interested in walking on the Moon; they wanted to understand what it was made of. One of the key experiments involved the Passive Seismic Experiment Package (PSEP). This device, equipped with seismometers, was left on the lunar surface by several of the Apollo Missions to measure moonquakes, meteor impacts, and even controlled explosions.

The goal? To observe seismic waves traveling through the Moon, which would help scientists determine its internal structure.

Crashing Spacecraft into the Moon

Here’s where things get REALLY interesting: NASA used deliberate spacecraft crashes to create seismic waves on the Moon. After the Apollo astronauts finished their missions, parts of their spacecraft, such as the ascent stages of lunar modules and the third stages of the Saturn V rockets, were deliberately crashed onto the Moon’s surface. These impacts created seismic events, which the PSEP instruments then recorded.

For instance, when the third stage of a Saturn V rocket collided with the Moon, the resulting seismic waves traveled through the lunar crust. By analyzing these waves, NASA could determine the thickness, density, and composition of the Moon’s outer layers.

The Ringing Bell Effect: Not a Hollow Moon!

Now, this is where things get weird. When NASA scientists crashed the Apollo 12 lunar module into the Moon at a speed of over 6,000 kilometers per hour, the Moon literally rang like a bell. This reverberation lasted for almost an hour, baffling scientists and sparking a ton of conspiracy theories. Some people claimed that this proved the Moon was hollow and might even contain alien bases. But the reality is far more interesting (and scientifically sound).

The Moon isn’t hollow—it just behaves differently from Earth. Because the Moon is smaller, drier, and colder than Earth, seismic waves travel through it for much longer. This is why impacts can make the Moon ring out like a bell, but it doesn’t mean there’s an empty core or secret underground cities.

What Did NASA Discover?

Through these seismic experiments, NASA found that the Moon’s interior is vastly different from Earth’s. Here are some key takeaways:

• Cold, dry composition: The Moon has much less seismic wave attenuation than Earth, meaning it’s cooler and lacks water deep inside.
• Layered structure: Just like Earth, the Moon has a layered interior, with a crust, mantle, and core. However, the core is much smaller and likely partially molten.
• Meteor impacts: By recording the impacts of meteors hitting the Moon, NASA also gathered invaluable data about the frequency and strength of these collisions over time.

Why It Matters

These seismic experiments helped answer long-standing questions about the Moon’s formation and structure. The data has been crucial in understanding planetary formation processes throughout the solar system. With future lunar missions on the horizon (like NASA’s upcoming Artemis program), this seismic knowledge will be key in determining where to build bases, how to mine resources, and even how to protect astronauts from natural lunar phenomena like moonquakes.
