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.

Last night I caught some stunning shots of the Waxing Gibbous Moon with an impressive 88% illumination. However, I couldn't spot much on Mars' surface—just a little too elusive for my telescope.

Spain Launches Its First Military Satellite: A Leap Forward in Space Technology*

On January 30th, Spain marked a historic milestone with the successful launch of its first military satellite, SPAINSAT NG 1. The satellite was launched from Cape Canaveral aboard a SpaceX Falcon 9 rocket and is now positioned in geostationary orbit, approximately 35,786 kilometers above Earth—nearly three times the planet's diameter.

Spain Launches Its First Military Satellite: A Leap Forward In Space Technology*

Operated by the Spanish company Hisdesat, SPAINSAT NG 1 is hailed as the most advanced satellite in Spain and the first in Europe equipped with cutting-edge technology antennas. This innovation includes X-band antennas and beam-hopping technology, enabling the satellite to redirect electronic signals without physical movement. Additionally, it boasts the ability to detect and neutralize interference on Earth, ensuring secure communications for Spanish military forces and NATO.

The satellite is expected to remain operational until 2037, providing reliable and secure communication capabilities. Looking ahead, its twin satellite, SPAINSAT NG II, is scheduled for launch around September or October 2025. Together, these satellites will cover two-thirds of the planet, securing communications from Denmark to Singapore.

This achievement underscores Spain's growing presence in the space sector and its commitment to advancing technological innovation.

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!

Exciting Discovery Alert!

Hey space enthusiasts, did you know that NASA's TESS has just uncovered a cosmic wonder?

NASA's exoplanet hunter just discovered a "weird" world named Phoenix that's defying expectations! This hot Neptune-sized planet is surprisingly small, old, and hot - and it's still got an atmosphere despite being super close to its red giant star.

According to the scientists, Phoenix should be a bare rock due to its proximity to the star, but instead, it is emerged from the flames with a nice and puffy atmosphere. It's a real mystery how it's managed to hang on!

Phoenix is part of a rare class of planets that orbit close to their stars, and its discovery shows just how diverse exoplanets can be. The team predicts that Phoenix will eventually spiral into its star in about 100 million years.

What can we learn from this peculiar planet? For one, it's giving us new insights on the late-stage evolution of planetary systems - including our own Earth! Who knows what secrets Phoenix holds about our planet's future?

So, let's get excited about this cosmic discovery and see what other mysteries NASA's TESS spacecraft will uncover!

Interview with Univision Nevada about the parcial solar eclipse event 2024

4 months ago

Just got back from an amazing time at the Death Valley Dark Sky Festival! I had the privilege of supporting the event with my telescope, and the experience was unforgettable.

The skies were incredibly clear and dark on Friday and Saturday nights, perfect for stargazing despite the chilly weather. We had the chance to see Jupiter and its satellite, Mars, Venus, as well as deep-sky objects like M42, M36, M31, M44, and M45.

During the day on Saturday and Sunday, from 10 to 4, I was at the Visitor Center with my solar telescope, observing the Sun.

We welcomed over 1000 stargazers each night and more than 500 visitors during the day. I absolutely love this event and can't wait for the next one!
