You've been asked to submit a proposal for a space exploration mission of your own desire, to the New Frontiers spaceflight program. These missions have a cost cap of approximately $700 million to $1 billion, and have famously produced the following spacecraft:

• New Horizons, a flyby probe to Pluto.
• Juno, a polar orbiter of Jupiter.
• OSIRIS-REx, a sample return mission to a rocky asteroid.
• Dragonfly, a drone lander to Saturn's moon Titan.

These are medium-sized missions in both scope, and cost. You can't build the Mars 2020 Rover, or the James Webb Space Telescope. What do you send, and where? Things to consider:

Technology Readiness Level

Administrators are less likely to choose your mission if you choose to integrate risky or untested flight hardware, or novel concepts into the mission design. You're more likely to get selected with more conventional hardware.

Power Source

Your best bet is probably solar panels, maybe something commercial off the shelf like NG's Ultraflex panels? The downside is that these are only effective up to about Jupiter's orbit, and generate power according to the inverse square law. How much do these cost and weigh? How much energy do you generate?

If you go further out into the solar system than that, you'll need a Radioisotope Thermoelectric Generator (RTG). There aren't many of those around, in fact, after Mars 2020 has taken its RTG, there's two left. What makes your mission deserving of an RTG? Is there enough power in the MMRTG to power your mission?

Propulsion

Does your mission need in-flight propulsion? Either for orbit insertion, landing, or maybe a long coast with Ion thrusters like Dawn? If the latter, you can get some pretty good Xenon-powered thrusters, like NEXT, which gives you 236mN of force from 7kW of input power (this rules out an RTG as your power source).

Don't need long-term burn capability? Maybe a COTS bipropellant engine like LEROS is your thing. Watch your weight though, bipropellants aren't efficient! Often more than half the mass of large spacecraft can be dedicated to just propulsion alone.

Instruments

Go crazy. What are you looking to research? Do you need a long range camera, a wide angle camera, something outside of the visible spectrum, a spectrometer, ground-penetrating radar? Do you have a mass-budget in mind?

Launch Vehicle

Every dollar you save on your launch vehicle, you get to add to your mission profile. Your best bet in terms of performance and cost is probably Falcon 9, which retails for $62-90 million, depending on the amount of assurance for success you need. Of course, if you can find a cheaper launch vehicle, feel free to pick it if it fits into your mission weight.

Objectives

What scientific questions do you want to answer? What are you interested in exploring the most?

I switched to the light theme the other day. I'm typically all-in with dark themes for everything, but there was some convincing research.

I started working on a light theme, but it's fairly basic.

• main feed
• thread view

I was digging through the old thread and found a few gems, but I'm wondering what everybody has been up to since. Time for some show and tell!

I can mention many movies that influenced me in major ways.

• Stand By Me made me realize the importance of friendship
• High Fidelity helped me understand romance is not entirely about passion. It's also about respect, love, and care. There's value in something that's simply "good", and "good" is not something to brush off.
• Goonies and Godfather showed that, when shit hits the fan, family is everything.
• Manhattan taught me love is nothing without courage
• A Bronx Tale taught me that our parent figures can be imperfect and even downright criminal, but this doesn't mean they don't love us.

Ant the list goes on...

So, what (or how) are you doing this weekend?

What drives you to create or do something new? Even seemingly straightforward motivations can have a pretty complex interaction of history and emotion behind the scenes.
What are the rates at which your motivation waxes and wanes? Does it come and go in a matter of days, weeks, or months? Or does it stay fairly consistent?
What steps would you take with the factors in an effort to increase your motivation?

What have you been doing lately for your own fitness? Try out any new programs or exercises? Have any questions for others about your training? Want to vent about poor behavior in the gym? Started a new diet or have a new recipe you want to share? Anything else health and wellness related?

My personal picks would be the whole of Chinese history between the opium wars and communist rule (or the century of humiliation as it is called), and most especially the warlord era, given that this was effectively how European powers, Japan and many internal revolutionaries managed to bring down the greatest economy in the world to civil war and then total warlordism for 40 years. For a vague concept, my pick would be the great divergence, the period where the US and European nations rose above the rest of the world and became the predominant world powers and colonized most of it, along with the many potential causes of this.

This question popped up between my friends and I when we were discussing the possibilities of lab grown meat. When discussing lab grown meat, one of the arguments for it is that it is far more ethical to consume as it didn't originate from a living, conscious being. But if you replace the meat being grown in a lab to human meat rather than fish or beef, is it still less ethical? Or is it something that will be seen as incredibly taboo to the point where it should be outlawed?

I would be curious to read your thoughts and points of view on this!

For me, it's going to be a hard no that it shouldn't it be done. But to be honest, I feel like my feelings regarding it come from an emotional perspective rather than a logical one.

Edit: Let's throw in lab grown human organs as well. Say these are the organs that aren't suitable for transplant, but are perfectly edible.

I'm always curious to see what languages people speak, especially given that most communication on sites like Tildes happens in English and as such it doesn't always come up.

At one point, I was pretty fluent in Spanish, but it's been about 4ish years since I've used it with any frequency and as such I am very rusty when speaking. I can still read and write it pretty well however. The big thing is that I have trouble these days recalling vocab I knew like the back of my hand... I should read more to stay sharp.

I also took some French in college and can read it at a beginner-intermediate level, basically enough to understand threads on not super complex topics. I can write too, but require a dictionary for anything remotely complex. Speaking I'm shit however - despite having great teachers I always had a tough time with pronunciation.

I (probably) have aphantasia, so I only dream when I'm actually trying to make my brain dream something, so I usually only dream to indulge in NSFW fantasies to jack off and despite this barely anything makes it into my mind. (I swear someone has said something like this before, I think they said they 'did it to embrace their kinks to improve mental health', which is quite unique and pretty cool.)

I recently finished "Zen Mind, Beginner’s Mind" by Shunryu Suzuki and was deeply moved. I've meditated sporadically over the years and dabbled in various Buddhist traditions yet never have I been so taken with an approach as I was after reading this. If there is anybody out there practicing Sōtō Zen would you be able to recommend anything to read next?

I'm sitting here eating a pan crust pizza with pepperoni, sausage, mozzarella+romano cheese, and easy mushroom and basil. I feel that this is an ideal pizza with it's mixture of crunch, spices, and sweetness. The leftovers are perfect for reheating in a skillet the next day. The crust has softened but is soaked with enough grease that the skillet makes the crust have an almost puff pastry style crunch/crumble. This is probably my ideal pizza.

I'm currently in the process of reading the excellent "Lessons Learned in Software Testing: A Context-Driven Approach". Early on the following is mentioned.

Test common threats before exotic threats.

Seems reasonable enough. That said, it got me thinking It'd be cool to generate a list of such threats for future devs/testers to draw on. So...I'm calling on the collective experience of any Tilders involved in iOS or Android development to lend a hand.

In your time working on mobile, what issues have you encountered that you would you classify as exotic? I.e those issues that infrequently arise but when they do can cause major damage. Any and all help is appreciated.

It was mentioned, and I agree, that Tildes is a little serious. As such, let's tell some jokes! And not good jokes. What's the fun in that? I want your worst clean joke. Aim for the groan, the hiss of pain, the holding of noses while fleeing into the night! Be it short form or shaggy dog, bring it here!

I'll start with the joke I pull out as an icebreaker:

Two muffins were sitting in the oven. One muffin said to the other: "Boy, is it getting hot in here, or is it just me?" The second muffin said "Ahhh! A talking muffin!"

It's terrible, I know. Can you top me?

Asked in the spirit of the new decade.

I am 14, so mostly growing up and realizing that the world is probably going to enter a recession when I reach adulthood which will suck for reaching financial independence.

Going through puberty, even if it's just the beginning of it and seeing one of my cats die from kidney failure and hearing that my grandma died from cancer, which is very sad :(

The end of the year has me in a movie-watching mood and I want to add the best of the best into my queue for the next few weeks. Similar to games of the decades, what are your movies of the decades and why?

All of us know the feeling; some of us have felt it more intensely than others; some of us have to continue to live with it daily.

When was the first time you really became aware of it? What did it feel like? How did it play out?

So, what (or how) are you doing this week?

It can be anything: possible/impossible, material/immaterial.

I want the Ergodox EZ programmable keyboard. In my estimations, taking into account currency exchange, shipping and import taxes, it would cost R$ 2323.2 (2323.2 Brazilian Reais) to bring one home. That's 232% of our minimum wage.

So I bought some cheap games on the PSN and a 15 dollars vertical mouse instead.

I'll start by saying yes and no, but the reasons for my answer are personal and familial ,so if you don't like that skip my answer.

It's the last week of the year! Although I generally believe that self-improvement projects can begin at any time, New Year is a popular time to reflect and to plan for the future.

So for some New Year's Resolution inspiration:
1. What was the most beneficial habit you built in 2019?
2. What is one habit you would like to build in 2020?
