The NASA Open Science Data Repository (expansion of @NASAGeneLab) has enabled biological & health discoveries helping humanity become multi-planetary by helping life thrive in deep space on Mars and 🌘 OSDR stores precious data anyone can use and analyze, plus a community of collaborative users anyone can join, and several public tools/trainings (including AI/ML) for space biology available 🧵

@astro_Pettit Awesome! Have you considered depositing/sharing these data in the NASA Physical Sciences Informatics data repo? That’s my bet for appropriate spot 😊 🔗Portal: psi.nasa.gov/physci/repo/se… 🔗About science.nasa.gov/physical-scien… It is NASA BPS supported

Scanning electron microscope look at the hopper crystals I grew on ISS. These are potassium chloride crystals exhibiting a relatively rare "scroll" morphology with step-like structures under weightless conditions.

@DJSnM @NASAAmes Many brilliant people across NASA contributed to the success of the Artemis II mission, but without Ames and the Arc Jet facility, we would not have gained the confidence we needed to fly the heat shield.

So many exciting things are happening in human spaceflight, including how we prepare humans for orbit. Traditional long duration NASA astronauts were trained as generalists. Because crew rotations and experiments changed so frequently, the focus was on adaptability, mastering station systems and being a jack of all trades. Private astronauts, assigned to shorter duration missions, are more like Shuttle astronauts.  They have assigned science portfolios and experiments, allowing them to tailor training to their specific needs. Being able to tailor the training to the specifics of the missions will be an important aspect as we develop a vibrant commercial LEO economy!

@yunta_tsai I knew this. But was unable to articulate it this plainly. Sorta profound statement. Also cuts across any topical domain. Reminds me of the below paper from a 2021 @NASA workshop rdcu.be/c8jSO

Most orgs work in silos, and AI breaks those silos.

🚨 New paper alert! Diagnostic imaging in space has been restricted to ultrasound for decades. But why? It's high time we changed that! We have a new paper out now bringing medical x-ray to space for the first time! Read on to see what we found... 🧵 (1/8)

Day 1 in orbit and I’m overwhelmed by gratitude, love, and beauty for this Earth we share. Hello from the international space station!

Congrats to Expedition 75, and a special shoutout to Astronaut @astro_anil! 🎉 Welcome flying by the United States! 🇺🇸 We're rooting for you, and everyone back home, from @NASAAmes @ASGSRSpace @OSMEDSpace 👋 Here's to eight months of great science in orbit. Watching the @Space_Station cross overhead tonight, I'll never tire of sky gazing and setting an alarm for the ISS pass. ❤️🚀🌎 Cheering the whole crew: Commander @Astro_Jessica, @astro_hathaway, @Soph_astro, and the @roscosmos cosmonauts Dubrov, Kikina & Fedyaev. Safe travels home soon, @Astro_ChrisW! 🫡 Cheers to the @NASA Spot the Station app for the front-row seat. @NASAAdmin @GeorgeAlderman_

@wingod @GeopoliticalBum @sedsusa Hadn’t heard of this. I’ll look into it more deeply. Thanks Dennis 💯

@RyanTScott @GeopoliticalBum @sedsusa Here is the Wikipedia page. (its not a very good page) en.wikipedia.org/wiki/SEDSAT-1

A friend just found an old journal of her’s from around 1992. In it was my first email address. I got that address in 1989.

@wingod @GeopoliticalBum @sedsusa

@RyanTScott @GeopoliticalBum @sedsusa Did I mention that our team built SEDSAT 1?

Baikonur, Kazakhstan: @astro_anil on his way to the International Space Station as his wife Anna and two children watch; such an incredible moment, brilliantly captured by @NASA / @johnkrausphotos. These and other Expedition 75 images are here: images.nasa.gov

1906 Nobel Prize winner Santiago Ramón y Cajal's 'Advice for a Young Investigator' makes important points: 1. The only thing in your power is your preparation 2. Be suspicious of “brilliance” 3. Be appropriately respectful of authority, but no more 4. Balance concentration and relaxation 5. Don’t worry about what it’s good for 6. Favor independence over resources 7. Embrace scientific panglossianism

@GeopoliticalBum SEDS = Students for the Exploration and Development of Space. I was the SEDS president at the time.

@wingod @interplanetary 😆

@interplanetary Since we were at UAH and UAH was part of the Alabama Supercomputer Network and we had an "umbrella" contract with MSFC we did not have to worry about plebeian things like that. 😁

Welcome aboard the International Space Station, @astro_anil. Your mission is just getting started. Wishing you and your crewmates a successful expedition as you advance research and inspire millions back here on Earth.

On the latest #HWHAP episode, NASA astronaut Anil Menon shares his journey ahead of his first spaceflight to the @Space_Station. Menon will launch aboard the Roscosmos Soyuz MS-29 on Tuesday, July 14, accompanied by cosmonauts Pyotr Dubrov and Anna Kikina, where they will join the Expedition 74 crew advancing scientific research. 👂here: go.nasa.gov/4aLDwNy

Focusing on usefulness, not benchmarks. There was a time when almost every ML paper focused on ImageNet-1K challenges that evaluated how well a model could correctly predict the main object in an image. We even occasionally saw headlines where AI beat humans on object detection. But such benchmarks often have a fatal flaw—they cannot measure new paradigm shifts, just like a benchmark for horses cannot be applied to cars. Over time, we are likely to optimize something that should not have been there in the first place. It was a good first-order proxy for a subset of usefulness, but not the whole end goal. Thus, it is critically important to keep an eye on the end game while working toward it. People courageous enough to do so might miss a few spotlight opportunities but eventually they are the ones who finish the game.

Sometimes watching these retro documentaries of US cities feels futuristic, and the present moment feels like a disintegrating past.
