14th April 2021

Hello world! To celebrate the five year anniversary of my little music-themed webcomic, The Crotchets ("crotchet" is the British English term for "quarter note"), I'm branching out to share my work on Tumblr.

The comic strip follows the misadventures of four bandmates and their manager, as they juggle their passion for music and amateur dramatics with their everyday responsibilities and various life events. Many of the comics are loosely based on my own experiences as an amateur performer, and over the years it has become an outlet for journaling my memories on stage and behind the scenes.

I publish a new comic every Wednesday over on Instagram, and am also working on a ComicFury website (which is up, but currently outdated).

“A lot of people would like to take after Cohen, I mean, he was the best fighter, the greatest thief, he—” “A lot of men would,” Conina snapped. She leaned against a wall and glared at him. “Listen,” she said, “There’s this long word, see, an old witch told me about it…can’t remember it…you wizards know about long words.” Rincewind thought about long words. “Marmalade?” he volunteered. She shook her head irritably. “It means you take after your parents.” Rincewind frowned. He wasn’t too good on the subject of parents. “Kleptomania? Recidivist?” he hazarded. “Begins with an H.” “Hedonism?” said Rincewind desperately. “Herrydeterry,” said Conina.

Happy Birthday, Jules Verne!

Considered by many to be the father of science fiction, French novelist Jules Verne takes his readers on a “From the Earth to the Moon,” “Twenty Thousand Leagues Under the Sea” and “Around the World in Eighty Days.” In his honor, let’s take our own journey around the world, exploring seven far-flung ground stations and the communications networks they support. These ground stations downlink data from science and exploration missions, maintaining the critical link from space to ground.

Our Deep Space Network supports far-out missions like Voyager 1, a spacecraft that’s now over 13 billion miles from Earth. To communicate that far, the Network uses antennas as large as 230 feet in diameter. The network has ground stations in Pasadena, California; Madrid, Spain; and this one in Canberra, Australia. The ground stations are strategically placed for maximum coverage of the night sky, ensuring that deep space missions can communicate their data back to Earth. Check out that lizard!

Our Space Network uses relay satellites in conjunction with ground stations to provide continuous communications coverage for satellites in low-Earth orbit like the International Space Station, enabling 24/7 connection with astronauts onboard. Spacecraft using the Space Network beam their data to the constellation of Tracking and Data Relay Satellites, which forward that data to the ground. This is a photo of a Space Network ground station in Guam, a U.S. territory. The spherical structures around the antennas are called “radomes” and protect the antennas from the tropical storms!

Optical communications uses lasers to provide missions with higher data rates than radio communications. Optical terminals also offer missions reduced size, weight and power requirements over comparable radio antennas. A smaller system leaves more room for science instruments, a weight reduction can mean a less expensive launch and reduced power allows batteries to last longer. This ground station in Haleakalā, Hawaii, will relay data to California through a groundbreaking optical communications satellite, the Laser Communications Relay Demonstration. The demonstration will show the power and promise of optical communications to support the next generation of science missions.

Antarctica may seem like an odd place for radio antennas, but McMurdo Ground Station is vitally important to our networks. In 2017, we used the McMurdo ground station to demonstrate a new technology called Disruption Tolerant Networking (DTN), sending a selfie from McMurdo to the space station through numerous DTN nodes. DTN protocols allow data to be stored at points along its route that do not have an open connection to the next intermediary, preventing data loss and improving data returns.

This Near Earth Network ground station in Santiago, Chile, might not be our only South American ground station for long. The Near Earth Network is considering Punta Arenas, Chile, as a possible location for Ka-band antennas, which would provide missions with higher data rates. The Near Earth Network is also experimenting with Ka-band arraying, which uses multiple smaller antennas to provide the same capabilities of a larger, Ka-band antenna. Ka-band services will greatly increase the amount of science data we can gather!

If the space station ever has communications trouble, we could communicate with our astronauts through emergency very high frequency (VHF) communications ground stations like this one in Wallops Island, Virginia. VHF offers voice-only, contingency communications for the station and the Soyuz spacecraft, which ferries astronauts to and from the station. We maintain two VHF stations strategically placed to maximize contact with the space station as it orbits above North America. International partners operate VHF stations that provide contacts as the station orbits above Asia and Europe. NASA’s segment of the VHF network recently underwent critical upgrades that improve the reliability and durability of the system.

This beautiful photo captures Near Earth Network antennas in Svalbard, Norway, beneath the glow of the Northern lights, a phenomenon that occurs when charged particles from the Sun interact with various gasses in Earth’s atmosphere. If one were to visit Iceland, one could see these same lights above Snæfellsjökull volcano, featured in Jules Verne’s “A Journey to the Center of the Earth” as the imaginary entrance to a subterranean world.

A lot has changed in the nearly two centuries since Jules Verne was born. Verne’s 1865 novel “From the Earth to the Moon” and its 1870 sequel “Around the Moon” imagine a giant cannon capable of launching three men into lunar orbit. These imaginary astronauts used opera glasses to survey the lunar surface before returning safely to Earth.

Such a story may seem ridiculous in an age where humanity has occupied space for decades and satellites explore distant worlds with increasing regularity, but Verne’s dreams of spaceflight were novel ­– if not revolutionary – at the time. This change in worldview reflects humanity’s inexorable technological progress and our mission at NASA to turn science fiction into science fact.

As the next generation of exploration commences, our ever-evolving communications capabilities rise to meet the demands of missions that dreamers like Verne could hardly imagine.

The BIG question.

My son is an artist and will sometimes have these questions.

So I figured I’d try to make a little sketch to answer it.

It’s VERY simplified.
