Here's a revised version of your social media post:

I spent a truly inspiring morning at Career Day sharing the wonders of space exploration and the groundbreaking opportunities of the Artemis program at the Luna base with children of all ages Their enthusiasm was contagious as I showed them videos of eating, drinking, and doing gymnastics in Leo orbit! From kindergarteners to high school students, their dreams and curiosity about living and working on the Lunar Base were palpable. A huge thank you to the teachers and students for this unforgettable experience!

First sunset of the spring

Thought of the day, Spring's Whisper in the Air

Though the celestial clock has yet to chime the official start of spring at 20:06 tonight, (Pacific time) the symphony of life around us is already tuning up to the melody of the season. #SpringIsHere in every sunbeam and sprouting leaf, and we're all invited to the early show!

Astronomically speaking, we're on the cusp of the vernal equinox, when day and night graciously share the stage in near-perfect balance. The Earth's tilt is about to bring us into a period of equal light and dark.

As we orbit our dependable star, we find ourselves in the embrace of warmer days, courtesy of the increasing angle of the sun's rays. It's a beautiful reminder that our planet's dance with the sun is as rhythmic as it is precise.

So while we count down the hours to the astronomical alignment that heralds the official start of spring, let's not wait to celebrate the changes all around us. The universe doesn't need an invitation to begin anew, and neither do we!

Feel the anticipation in the air? That's the universe conspiring to bring forth blossoms, longer days, and the freshness of a world reborn. Let's step outside and join the cosmic ballet!

The Nancy Grace Roman Space Telescope’s flight harness is transferred from the mock-up structure to the spacecraft flight structure.

Your Body is Wired Like a NASA Space Telescope. Sort Of.

If our Nancy Grace Roman Space Telescope were alive, its nervous system would be the intricate wiring, or “harness,” that helps different parts of the observatory communicate with one another. Just like the human body sends information through nerves to function, Roman will send commands through this special harness to help achieve its mission: answering longstanding questions about dark energy, dark matter, and exoplanets, among other mind-bending cosmic queries. 

Roman’s harness weighs around 1,000 pounds and is made of about 32,000 wires and 900 connectors. If those parts were laid out end-to-end, they would be 45 miles long from start to finish. Coincidentally, the human body’s nerves would span the same distance if lined up. That’s far enough to reach nearly three-fourths of the way to space, twice as far as a marathon, or eight times taller than Mount Everest!

Over a span of two years, 11 technicians spent time at the workbench and perched on ladders, cutting wire to length, carefully cleaning each component, and repeatedly connecting everything together.  

Space is usually freezing cold, but spacecraft that are in direct sunlight can get incredibly hot. Roman’s harness went through the Space Environment Simulator – a massive thermal vacuum chamber – to expose the components to the temperatures they’ll experience in space. Technicians “baked” vapors out of the harness to make sure they won’t cause problems later in orbit.  

Technicians work to secure Roman’s harness to the interior of the spacecraft flight structure. They are standing in the portion of the spacecraft bus where the propellant tanks will be mounted.  

The next step is for engineers to weave the harness through the flight structure in Goddard’s big clean room, a space almost perfectly free of dust and other particles. This process will be ongoing until most of the spacecraft components are assembled. The Roman Space Telescope is set to launch by May 2027.
