New Horizons is now *three days away* from shutting off its two heliophysics instruments, simply because NASA has not provided the $2M in funding it had promised to the mission last year or this year. There is no science basis for shutting these off. Our earlier coverage:

Working on my Mars slides for class, which means it's time to bring back my favorite slide I've ever made:

The "we're so back/it's so over meme" that has been edited so the x-axis is time from 1960 through 2040. The plot oscillates semi-sinusoidally between positive (we're so back) and negative (it's so over). It's labeled Mars Exploration Timeline.

The start of the timeline is small oscillations close to zero. These are labeled: first Soviet attempts (note: none of the Soviet attempts worked but they sure tried). The steep positive peak next to it, we're back, is labeled Viking landers. Then a massive negative, it's so over, is labeled: everyone crashes in the 90s. Look up Mars exploration to learn more about this. Then an even larger positive spike, we're so back, is for Curiosity and the other Mars rovers. Then a positive/negative combined spike is labeled Mars 2020 (for various reasons). Then a last negative, it's over (real) is labeled Mars Sample Return. This is accurate.

Not word-for-word since I lost the review with my old MS email, which I really wish I had kept. In 2019, there were only a few Venus posters at LPSC, compared with the scale of Venus research now, despite still using data that are more than 30 years old.

I recently dug back out my M.S. work for some other stuff. It was rejected by a journal deservedly. But I still remember Reviewer #2 (amouyous) saying they stopped reading after page 3 because it was bad, and the Venus data were already more than 20 years old, and there was “nothing to discover.”

It's me, the mythical STEM PhD who not only took history classes but got a whole history degree! Studying history is arguably one of the most important things STEM students can do. Science isn't done in a vacuum, and students should investigate the people, places, and events that shape it.

This is a piece of the Moon. It's a polymict breccia, part of the lunar highlands, and was collected by the crew of Apollo 16. It's 3.9 billion years old, or about 28% the age of the observable universe.

This was funded in part by $860,000 that the patient's parents scraped together. The original manuscript included the patient's info and funding acknowledgment, but both were removed after the patient's death in the review process. Yet the paper was still published.

"In a June response to an email from the parents noting their child’s death and other concerns, Nature’s deputy editor, Victoria Aranda, wrote that the ethical issues they raised “fall outside our purview in terms of data integrity” and that the matter should be handled by the university."

The blend of culture, history, and science is what makes this book so enjoyable, like how Japanese folklore explains earthquakes as Namazu, a giant catfish thrashing underground. Long before seismometers, people were already trying to make sense of the giants beneath their feet. 🐟
