The Terran R program entered a new phase in May as stage 2 rolled out of Long Beach and began its journey to NASA Stennis.

🏗️ Build: Completed stage 2 integration while advancing thrust structure, interstage, and stage 1 qualification hardware.
🔥 Test: Aeon V second stage engine completed its qualification campaign, hitting key service life, duration, and start milestones for flight one.
🌴Launch: Water tower reached its final height at 305 feet; lightning protection system erection continued

We're going to conduct science at Mars.🔴 Yesterday we announced the Interplanetary Sciences Program. Today, let’s take a closer look at the ground-breaking technology we're developing and launching to the Red Planet:
📡 A shallow radar sounder built by us to map subsurface ice and geology, revealing climate and geologic history, habitability conditions, and high-value landing sites
🖥️A Relay Data Center built by us to deliver networked optical and RF communication, run advanced algorithms and AI models, support autonomous responsive science operations, and return massive data volumes to Earth.
🔬 An atmospheric profiling suite built by @NASAAmes to measure winds, temperatures, clouds, dust and planetary energy balance.

💫 More missions. More science. More discovery. Today, we're launching the Interplanetary Sciences Program to advance deep space science missions through foundational technologies and payloads.

Proud to partner with @NASA , industry, and academic institutions on a science orbiter mission to Mars in 2028 for philanthropic customer.

What we discover belongs to everyone. All scientific data will be released to the world, fostering open collaboration.
