I've not asked since I've followed you, but what part of instrument engineering do you do (if you're willing to share)? I tangentially work with a lot of instruments and every time I just ask I get to learn from folks like you

Oh hey! Sorry if this took me a bit to get to, I have no idea how long ago you sent this!

So I do instrument systems engineering, which means a lot of things depending on who you ask, but basically I work on interfaces.

It's helpful to think about the instruments, or "Payload", as separate from the vehicle, or "Spacecraft". The Spacecraft is everything we need in order to get where we're going - so solar panels and batteries, the main computer, thrusters, etc. - and the Payload is what we do when we actually get there.

I'm the interface between the Payload and the Spacecraft. So, I work with the Spacecraft team to make sure the vehicle is providing adequate power to the instruments, has the right command and telemetry protocols, heats and cools the instruments appropriately, and and reacts correctly in the event of faults.

In the other direction, I also work with the instrument teams to make sure the instruments are capable of collecting the data that the project scientists are interested in.

It's a good mix of engineering and science, which is exactly where I want to be! I'm a bit of a jack-of-all-trades, and I enjoy it. I like that I can take bite-sized pieces of areas that people spend full careers becoming experts in. I don't want to be a thermal engineer, or an electrical engineer, or a power engineer or a small-bodies asteroid scientist, but I love that I can work with and learn from all of them!

GOES-U Launches to Space by NASA on The Commons Via Flickr: A SpaceX Falcon Heavy rocket carrying the National Oceanic and Atmospheric Administration (NOAA) GOES-U (Geostationary Operational Environmental Satellite U) lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Tuesday, June 25, 2024. The GOES-U satellite is the final satellite in the GOES-R series, which serves a critical role in providing continuous coverage of the Western Hemisphere, including monitoring tropical systems in the eastern Pacific and Atlantic oceans. On board GOES-U is a suite of seven instruments for collecting advanced imagery and atmospheric measurements, providing real-time mapping of lightning activity, and detecting approaching space weather hazards. Also onboard for the first time is the compact coronagraph that will observe the Sun’s outermost layer, called the corona, for large explosions of plasma that could produce geomagnetic solar storms.

Solid State Quantum MagnetometersSeeking out water worlds from the quantum world

“Follow the water!”  The solar system is full of water in different states, from the Sun’s water vapor to the ice of Pluto and beyond. Water is not only linked to the possibility to sustain life, it is also interesting for its own geological properties and potential uses. For example, ice on the Moon and Mars could support human exploration. Comets that hit Earth may have deposited water on our planet. The icy comets and rings of Saturn reveal how solar systems change over time. from NASA https://ift.tt/HFcznDG

Let's Explore a Metal-Rich Asteroid 🤘

Between Mars and Jupiter, there lies a unique, metal-rich asteroid named Psyche. Psyche’s special because it looks like it is part or all of the metallic interior of a planetesimal—an early planetary building block of our solar system. For the first time, we have the chance to visit a planetary core and possibly learn more about the turbulent history that created terrestrial planets.

Here are six things to know about the mission that’s a journey into the past: Psyche.

1. Psyche could help us learn more about the origins of our solar system.

After studying data from Earth-based radar and optical telescopes, scientists believe that Psyche collided with other large bodies in space and lost its outer rocky shell. This leads scientists to think that Psyche could have a metal-rich interior, which is a building block of a rocky planet. Since we can’t pierce the core of rocky planets like Mercury, Venus, Mars, and our home planet, Earth, Psyche offers us a window into how other planets are formed.

2. Psyche might be different than other objects in the solar system.

Rocks on Mars, Mercury, Venus, and Earth contain iron oxides. From afar, Psyche doesn’t seem to feature these chemical compounds, so it might have a different history of formation than other planets.

If the Psyche asteroid is leftover material from a planetary formation, scientists are excited to learn about the similarities and differences from other rocky planets. The asteroid might instead prove to be a never-before-seen solar system object. Either way, we’re prepared for the possibility of the unexpected!

3. Three science instruments and a gravity science investigation will be aboard the spacecraft.

The three instruments aboard will be a magnetometer, a gamma-ray and neutron spectrometer, and a multispectral imager. Here’s what each of them will do:

Magnetometer: Detect evidence of a magnetic field, which will tell us whether the asteroid formed from a planetary body

Gamma-ray and neutron spectrometer: Help us figure out what chemical elements Psyche is made of, and how it was formed

Multispectral imager: Gather and share information about the topography and mineral composition of Psyche

The gravity science investigation will allow scientists to determine the asteroid’s rotation, mass, and gravity field and to gain insight into the interior by analyzing the radio waves it communicates with. Then, scientists can measure how Psyche affects the spacecraft’s orbit.

4. The Psyche spacecraft will use a super-efficient propulsion system.

Psyche’s solar electric propulsion system harnesses energy from large solar arrays that convert sunlight into electricity, creating thrust. For the first time ever, we will be using Hall-effect thrusters in deep space.

5. This mission runs on collaboration.

To make this mission happen, we work together with universities, and industry and NASA to draw in resources and expertise.

NASA’s Jet Propulsion Laboratory manages the mission and is responsible for system engineering, integration, and mission operations, while NASA’s Kennedy Space Center’s Launch Services Program manages launch operations and procured the SpaceX Falcon Heavy rocket.

Working with Arizona State University (ASU) offers opportunities for students to train as future instrument or mission leads. Mission leader and Principal Investigator Lindy Elkins-Tanton is also based at ASU.

Finally, Maxar Technologies is a key commercial participant and delivered the main body of the spacecraft, as well as most of its engineering hardware systems.

6. You can be a part of the journey.

Everyone can find activities to get involved on the mission’s webpage. There's an annual internship to interpret the mission, capstone courses for undergraduate projects, and age-appropriate lessons, craft projects, and videos.

You can join us for a virtual launch experience, and, of course, you can watch the launch with us on Oct. 12, 2023, at 10:16 a.m. EDT!

For official news on the mission, follow us on social media and check out NASA’s and ASU’s Psyche websites.

Io's Missing Magma Ocean

In the late 1970s, scientists conjectured that Io was likely a volcanic world, heated by tidal forces from Jupiter that squeeze it along its elliptical orbit. Only months later, images from Voyager 1's flyby confirmed the moon's volcanism. Magnetometer data from Galileo's later flyby suggested that tidal heating had created a shallow magma ocean that powered the moon's volcanic activity. But newly analyzed data from Juno's flyby shows that Io doesn't have a magma ocean after all. (Image credit: NASA/JPL/USGS; research credit: R. Park et al.; see also Quanta) Read the full article
