Love Letters from Space

Love is in the air, and it’s out in space too! The universe is full of amazing chemistry, cosmic couples held together by gravitational attraction, and stars pulsing like beating hearts.

Celestial objects send out messages we can detect if we know how to listen for them. Our upcoming Nancy Grace Roman Space Telescope will help us scour the skies for all kinds of star-crossed signals.

All-Star Moments in Space Communications and Navigation

How do we get information from missions exploring the cosmos back to humans on Earth? Our space communications and navigation networks – the Near Space Network and the Deep Space Network – bring back science and exploration data daily.

Here are a few of our favorite moments from 2024.

1. Hip-Hop to Deep Space

The stars above and on Earth aligned as lyrics from the song “The Rain (Supa Dupa Fly)” by hip-hop artist Missy Elliott were beamed to Venus via NASA’s Deep Space Network. Using a 34-meter (112-foot) wide Deep Space Station 13 (DSS-13) radio dish antenna, located at the network’s Goldstone Deep Space Communications Complex in California, the song was sent at 10:05 a.m. PDT on Friday, July 12 and traveled about 158 million miles from Earth to Venus — the artist’s favorite planet. Coincidentally, the DSS-13 that sent the transmission is also nicknamed Venus!

Warm yourself by the fire, NASA style!

Look no further than this cozy and relaxing fireplace – complete with four RS-25 rocket engines to fill your hearth with light. (And 8.8 million pounds of thrust to power your party to the Moon.)

After 4 years of work, I've finally published my very first peer-reviewed theory paper: Design rules for controlling active topological defects

(and it's open access! :D)

I am sooo excited to finally be able to share this! I'll probably write some more in the future about what it was like to work on this project, but for now here's what I want to say about it:

I think this work is a beautiful example of how the long, meandering paths of curiosity-driven research can bring us in completely unexpected directions, yielding new ideas and technologies that might never have been found by problem- or profit-driven research.

We started this project because we were interested in the fundamental physics of active topological defects; we wanted to understand and develop a theory to explain their effective properties, interactions, and collective behaviors when they're hosted by a material whose activity is not constant throughout space and time.

Along the way, we accidentally stumbled into a completely new technique for controlling the flow of active 2D nematic fluids, by using symmetry principles to design activity patterns that can induce self-propulsion or rotation of defect cores. This ended up being such a big deal that we made it the focus of the paper, for a few reasons:

Right now the technique has only been demonstrated in simulations, but there are a number of experimental groups who are working on the kinds of materials that we might be able to try this in, so hopefully I'll get to see experimental verification someday soon!

Tiny BurstCube's Tremendous Travelogue

Meet BurstCube! This shoebox-sized satellite is designed to study the most powerful explosions in the cosmos, called gamma-ray bursts. It detects gamma rays, the highest-energy form of light.

BurstCube may be small, but it had a huge journey to get to space.

4 Little Known Women Who Made Huge Contributions to NASA

Women have always played a significant role at NASA and its predecessor NACA, although for much of the agency’s history, they received neither the praise nor recognition that their contributions deserved. To celebrate Women’s History Month – and properly highlight some of the little-known women-led accomplishments of NASA’s early history – our archivists gathered the stories of four women whose work was critical to NASA’s success and paved the way for future generations.

Black Scientists and Engineers Past and Present Enable NASA Space Telescope

The Nancy Grace Roman Space Telescope is NASA’s next flagship astrophysics mission, set to launch by May 2027. We’re currently integrating parts of the spacecraft in the NASA Goddard Space Flight Center clean room.

Once Roman launches, it will allow astronomers to observe the universe like never before. In celebration of Black History Month, let’s get to know some Black scientists and engineers, past and present, whose contributions will allow Roman to make history.

Dr. Beth Brown

The late Dr. Beth Brown worked at NASA Goddard as an astrophysicist. in 1998, Dr. Brown became the first Black American woman to earn a Ph.D. in astronomy at the University of Michigan. While at Goddard, Dr. Brown used data from two NASA X-ray missions – ROSAT (the ROentgen SATellite) and the Chandra X-ray Observatory – to study elliptical galaxies that she believed contained supermassive black holes.  

With Roman’s wide field of view and fast survey speeds, astronomers will be able to expand the search for black holes that wander the galaxy without anything nearby to clue us into their presence.

For the Benefit of All: Assistive Tech Developed from NASA Tech

What do modern cochlear implants and robotic gloves have in common? They were derived from NASA technology. We’ve made it easier to find and use our patented inventions that could help create products that enhance life for people with disabilities.

October is National Disability Employment Awareness Month, which highlights the contributions of American workers with disabilities – many of whom use assistive technology on the job. Take a look at these assistive technologies that are NASA spinoffs.
