Ultra-Close Orbits of Saturn = Ultra-Cool Science

On Sept. 15, 2017, our Cassini spacecraft ended its epic exploration of Saturn with a planned dive into the planet’s atmosphere–sending back new science to the very last second. The spacecraft is gone, but the science continues!

New research emerging from the final orbits represents a huge leap forward in our understanding of the Saturn system – especially the mysterious, never-before-explored region between the planet and its rings. Some preconceived ideas are turning out to be wrong while new questions are being raised. How did they form? What holds them in place? What are they made of?

Six teams of researchers are publishing their work Oct. 5 in the journal Science, based on findings from Cassini’s Grand Finale. That’s when, as the spacecraft was running out of fuel, the mission team steered Cassini spectacularly close to Saturn in 22 orbits before deliberately vaporizing it in a final plunge into the atmosphere in September 2017.

Knowing Cassini’s days were numbered, its mission team went for gold. The spacecraft flew where it was never designed to fly. For the first time, it probed Saturn’s magnetized environment, flew through icy, rocky ring particles and sniffed the atmosphere in the 1,200-mile-wide (2,000-kilometer-wide) gap between the rings and the cloud tops. Not only did the engineering push the spacecraft to its limits, the new findings illustrate how powerful and agile the instruments were.

Many more Grand Finale science results are to come, but today’s highlights include:

Complex organic compounds embedded in water nanograins rain down from Saturn’s rings into its upper atmosphere. Scientists saw water and silicates, but they were surprised to see also methane, ammonia, carbon monoxide, nitrogen and carbon dioxide. The composition of organics is different from that found on moon Enceladus – and also different from those on moon Titan, meaning there are at least three distinct reservoirs of organic molecules in the Saturn system.

For the first time, Cassini saw up close how rings interact with the planet and observed inner-ring particles and gases falling directly into the atmosphere. Some particles take on electric charges and spiral along magnetic-field lines, falling into Saturn at higher latitudes – a phenomenon known as “ring rain.” But scientists were surprised to see that others are dragged quickly into Saturn at the equator. And it’s all falling out of the rings faster than scientists thought – as much as 10,000 kg of material per second.

Scientists were surprised to see what the material looks like in the gap between the rings and Saturn’s atmosphere. They knew that the particles throughout the rings ranged from large to small. They thought material in the gap would look the same. But the sampling showed mostly tiny, nanograin- and micron-sized particles, like smoke, telling us that some yet-unknown process is grinding up particles. What could it be? Future research into the final bits of data sent by Cassini may hold the answer.

Saturn and its rings are even more interconnected than scientists thought. Cassini revealed a previously unknown electric current system that connects the rings to the top of Saturn’s atmosphere.

Scientists discovered a new radiation belt around Saturn, close to the planet and composed of energetic particles. They found that while the belt actually intersects with the innermost ring, the ring is so tenuous that it doesn’t block the belt from forming.

Unlike every other planet with a magnetic field in our Solar System, Saturn’s magnetic field is almost completely aligned with its spin axis. Think of the planet and the magnetic field as completely separate things that are both spinning. Both have the same center point, but they each have their own axis about which they spin. But for Saturn the two axes are essentially the same – no other planet does that, and we did not think it was even possible for this to happen. This new data shows a magnetic-field tilt of less than 0.0095 degrees. (Earth’s magnetic field is tilted 11 degrees from its spin axis.) According to everything scientists know about how planetary magnetic fields are generated, Saturn should not have one. It’s a mystery physicists will be working to solve.

Cassini flew above Saturn’s magnetic poles, directly sampling regions where radio emissions are generated. The findings more than doubled the number of reported crossings of radio sources from the planet, one of the few non-terrestrial locations where scientists have been able to study a mechanism believed to operate throughout the universe. How are these signals generated? That’s still a mystery researchers are looking to uncover.

For the Cassini mission, the science rolling out from Grand Finale orbits confirms that the calculated risk of diving into the gap – skimming the upper atmosphere and skirting the edge of the inner rings – was worthwhile.

Almost everything going on in that region turned out to be a surprise, which was the importance of going there, to explore a place we’d never been before. And the expedition really paid off!

Analysis of Cassini data from the spacecraft’s instruments will be ongoing for years to come, helping to paint a clearer picture of Saturn.

Couture Beyond, Guo Pei

The first major book on China’s leading couture visionary reveals the intricate craftsmanship and imperial glamour that has fashion publications worldwide declaring Guo Pei’s creations ‘the empire’s new clothes.’

An exponent of artisan craftsmanship and theatrical fantasy often compared to Alexander McQueen and Sarah Burton, Guo Pei dresses Chinese state dignitaries and American celebrities alike in richly bejeweled creations of imperial opulence. The designer’s first monograph, published on the occasion of her first solo exhibition, offers insight into the growing global influence of China and the complexities of its cultural transition.

‘am i Having A Brain Problem or Being a Shithead’: a short procrastination checklist

aka why tf am i procrastinating on The Thing (more like a flowchart, actually)

lots of people who have executive function difficulties worry about whether they’re procrastinating on a task out of laziness/simply wanting to be a jerk or mental struggles. this checklist might help you figure out which it is at any given time! (hint: it’s almost never laziness or being a jerk.) (obligatory disclaimer: this is just what works for me! something different might work better for you.)

1) do I honestly intend to start the task despite my lack of success?

yes: it’s a Brain Problem. next question

no: it’s shitty to say one thing & do another. better be honest with myself & anyone expecting me to do the task.

2) am I fed, watered, well-rested, medicated properly, etc?

yes: next question

no: guess what? this is the real next task

3) does the idea of starting the task make me feel scared or anxious?

yes: Anxiety Brain. identify what’s scaring me first.

no: next question

4) do I know how to start the task?

yes: next question

no: ADHD Brain. time to make an order of operations list.

5) do I have everything I need to start the task?

yes: next question

no: ADHD Brain lying to me about the steps again, dangit. first task is ‘gather the materials’.

6) why am i having a hard time switching from my current task to this new task?

i’m having fun doing what i’m doing: it’s okay to have fun doing a thing! if task is time-sensitive, go to next question.

i have to finish doing what i’m doing: might be ADHD brain. can I actually finish the current task or will I get trapped in a cycle? does this task really need to be finished?

the next task will be boring/boring-er than the current task: ADHD brain. re-think the next task. what would make it exciting? what am I looking forward to?

I might not have enough time to complete the task: ADHD brain wants to finish everything it starts. (if task is time-sensitive, go to next question)

i just want to make the person who asked me to do it angry: sounds like anxiety brain trying to punish itself, because I know I’ll be miserable if someone is angry at me. why do i think I deserve punishment?

no, I seriously want to piss them off: okay, i’m being a shithead

7) have I already procrastinated so badly that I now cannot finish the task in time?

yes: ADHD brain is probably caught in a guilt-perfection cycle. since I can’t have the task done on time, i don’t even want to start.

reality check: having part of a thing done is almost always better than none of a thing done. if I can get an extension, having part of it done will help me keep from stalling out until the extension deadline. i’ll feel better if I at least try to finish it.

no, there’s still a chance to finish on time: ADHD brain thinks that I have all the time in the world, but the truth is I don’t. 

reality check: if i’m having fun doing what I’m doing, I can keep doing it, but I should probably set a timer & ask someone to check on me to make sure I start doing the task later today.

8) I’ve completed the checklist and still don’t know what’s wrong!

probably wasn’t honest enough with myself. take one more look.

if I’m still mystified, ask a friend to help me talk it out.

hope this helps some of you! YOU’RE DOING GREAT SWEETIE DON’T GIVE UP ON YOU
