Several speakers detailed the need for space nuclear and aerospace capabilities to be brought together; also, emphasized the opportunity for universities and students. @JustinCKasper: it's an incredible opportunity for you to apply your skills in nuclear power and propulsion

@GrossWeather @UMich @umclasp Thanks @GrossWeather! And we’re just less than a year away from our closest approaches to the Sun.

Great explanation, Erika! Thanks for taking the time…you rock. My followers will find this especially interesting because of a big local connection: one of the mission’s principal investigators is @umich’s @umclasp Professor @JustinCKasper!

Counting down. One year until Parker’s closest approach to the Sun!

Farewell B1058, you were a good rocket 🥹

The Falcon fleet’s life leading rocket completed its 19th and final launch and landing on December 23. This one reusable rocket booster alone launched to orbit 2 astronauts and more than 860 satellites — totaling 260+ metric tons — in ~3.5 years

It wouldn't fit under the tree, but we were excited to unwrap a new steam generator for Unit 5 just in time for the holidays! Thank you to our MCR Rigging and Lifting team, and BWXT, Western Mechanical, E.S. FOX and the Ironworkers Union for this successful delivery.

This is, in my opinion, some of the most exciting research underway. Oceans on other planets!

Still one of my favorite films. I liked to think Discovery had 3 nuclear thermal rockets.

This is such an exciting idea, using the heat from a small nuclear reactor to melt ice and tunnel into the oceans of icy water moons.

Earlier this year, a team of experts gathered to discuss a mission concept to detect water and search for life under the icy crusts of moons that orbit Jupiter and Saturn: the cryobot, a cylindrical probe that employs state-of-the-art technologies to drill and investigate beneath the ice: science.nasa.gov/science-resear…

The SunRISE Mission is gearing for launch! Led by P.I. Professor Justin Kasper, the mission will study emissions from the sun. Read on: jpl.nasa.gov/news/nasas-6-p… #UMClimateSpace #NASA #JPL @NASAjpl @NASA

Did you know that Expo City, in Dubai, where COP28 is being held, glows at dusk from hundreds of lights shaped exactly like nuclear reactor fuel assemblies? Nuclear-powered, nuclear-themed public art at COP28! On winter nights in the UAE, most of the power is actually coming from the local Barakah nuclear plant, from fuel like these! I have it on good authority this was intentional. How could it not? Compare it to the 4th picture, the real deal for a Westinghouse reactor. Nuclear-powered nuclear art: I've never seen such a thing before. It really shows the pride that this country has in its new nuclear plant, which was being built at exactly the same time as Expo City. An estimated 24 million visitors walked by these nuclear lights during Expo 2020 in 2021, Do you think any of them realized what they were walking by? Or, for that manner, where the electricity was coming from?

@nepetro @DrSteveElardo Some good candidate rover names here…

@DrSteveElardo Perserverance - Decent rover, 3/5

@marsokod @NASAJPL @UMich Here’s a paper on the mission ieeexplore.ieee.org/document/91724…. One of our tricks is we use GNSS to measure precisely where we are in real time instead of forcing the spacecraft into precise locations. Thrusters just keep array in general locations.

@JustinCKasper @NASAJPL @UMich The formation flying management on these must be really interesting. Looks like the thrust vectoring is very flexible. Are there papers published on that topic?

An iconic photo of our SunRISE spacecraft, ready to launch! These spacecraft are individually highly capable but will act in concert in orbit to create a virtual radio telescope 10km in diameter! My gratitude to the team at @NASAJPL SDL and @UMich for this historic milestone.

@NASAScienceAA Congratulations on the exciting week @NASAScienceAA. My highlight was when we announced our six SunRISE spacecraft are ready for flight! jpl.nasa.gov/news/nasas-6-p…

Pat yourselves on the back! 🎉 We’ve made it to December, and what a week it has been. I’d love to know – what were some highlights of your week? Comment below! Here are some of mine:

Half a dozen cubesats working together to study the Sun? Sounds like a project for @umclasp's @JustinCKasper! Read more about this project by following the link in @NASAJPL's post.

@LynntheBruce Cool! Any correlations with local plasma parameters? I was expecting something related to Debye length or plasma temperature might be important. Or spacecraft temperature?

My recent paper on spacecraft charging was just published in ApJS at doi.org/10.3847/1538-4…
