Jared Espley

I work for NASA exploring the Solar System, occasionally get paid to write D&D adventures, and whitewater kayak when I can.

I was just glad to not be working in my home office in my basement.

At the entrance to Valentine Cave, @NASAGoddard's Jared Espley and Yasmina Martos take one final set of measurements--for this worksite, anyway! Jared, Yasmina, Dave, and the rest of the magnetism team will investigate at least 6 more lava tunnels this week.

Truly fascinating. I zoomed in with my Mastcam-Z camera on a Phobos solar eclipse. This detailed video can help scientists on my team better understand the Martian moon’s orbit and how its gravity affects the interior of Mars, including its crust & mantle. https://t.co/jVdJ4UwhDx

Excellent thread about true colors of objects in our Solar System. Scroll through to see the other objects.

[Corey S. Powell @coreyspowell]

The true colors of the solar system, a short thread. * First, let's start with the Sun. Can we all agree it's white to the eye?

* inspired by James O’Donoghue & Marina Koren, with some color corrections by me.

Piers Sellers is best known for being an astronaut, but his true legacy was in Earth science, a big focus during his career at Goddard. https://t.co/U7EuLTwuuQ

NASA SENIOR REVIEW IS IN! Getting excited for Extended Mission 5 (EM5). @MAVEN2Mars will be observing #Mars during the peak of #solarcycle25 AND dust storm season 🤯🚀⚡️🌪 #PI_daily

[Klaus Pontoppidan @pontoppi]

🧵One of my very favorite #JWST science stories concerns the mirror gold. This seem like a good time to tell it. As with all good stories, it has been told before, but I think it is worth a rant. And at the end, there will be a twist. 1/

I am advertising a PhD project exploring the impact of complex turbulent fluctuations on Earth's solar wind - magnetosphere interaction using spacecraft observations and numerical simulations!

***PhD offer*** at @PhysicsUoL to study Mars’ ionosphere with myself and the amazing planetary team @uniofleicester with several missions such as Mars Express @esascience, MAVEN @MAVEN2Mars and MRO. https://t.co/fqEsLg7OfI

Hello, old friend. Yesterday our #JunoMission made the first close flyby of Jupiter’s giant moon Ganymede in more than 20 years, and the first two images have been received on Earth. 📸 More to come. See details at: https://t.co/zIVMO6waKH

Stratigraphy and Volumes of the Units Within the Massive Carbon Dioxide Ice Deposits of Mars https://t.co/ct7XqSMyaw Radar soundings measurements of the thickness, extent, and volume of alternating H2O and CO2 ice units help constrain the last the past 500 kyr of climate history

Where are Mars’ Hypothesized Ocean Shorelines? Large Lateral and Topographic Offsets Between Different Versions of Paleoshoreline Maps https://t.co/KgvRgzdaT2 The placements of hypothesized shorelines on maps are both inconsistent and inaccurate with offsets in excess of 1000 km

Here's how the Sun's magnetic field intensity, B, varies from minutes to millennia.

This uses data from spacecraft, Victorian-era compasses, sunspot records, tree trunks and ice cores.

Impact of the 2018 Mars Global Dust Storm on the Ionospheric Peak: A Study Using a Photochemical Model https://t.co/dCHFpdv1sw The altitude of the ionospheric peak increased by 7–10 km over 22–26 days during the onset phase of the global storm in 2018.

Jupiter’s Great Red Spot: Strong Interactions With Incoming Anticyclones in 2019
https://t.co/d6dE4QZAdG Anticyclones interacted with the Great Red Spot, eroding and distorting it. The interactions are not necessarily destructive but can even transfer energy to the Great Red Spot

Love it. Took me a while to find @TheRealBuzz...

Sometimes it is so hard to get a good appreciation of the spatial and temporal scales of nature. Good job, @JPMajor! #findBuzz

INTERSTELLAR OBJECT ‘OUMUAMUA IS LIKELY A PIECE OF A PLUTO-LIKE PLANET A new study resolves the not-quite-comet-like character of a strange visitor from beyond our solar system https://t.co/KBlDZHINnH A joint press release about two papers just available at JGR: Planets! #AGUpubs

[Jared Espley @JaredEspley]

So proud of my colleagues who made this discovery. Some discoveries are easy if you're in the right place but this one required very careful analysis of unexpected data and dogged persistence in getting it peer reviewed and published.

[NASA Solar System @NASASolarSystem]

The #JunoMission to Jupiter has made an unexpected discovery about a different planet – Mars. Juno scientists have found evidence that dust from the Red Planet may be the source of a luminous sky phenomenon known as the zodiacal light: https://t.co/R4DXfMzjqb

Magnetic Induction Responses of Jupiter's Ocean Moons Including Effects From Adiabatic Convection https://t.co/tY8XK3huDN Electrical conductivity variations change the magnetic fields by >1 nT. Europa Clipper and JUpiter ICy moons Explorer (JUICE) missions can resolve that!
