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.

It's been quiet from my end lately—I mentioned in a comment last week that I had been taking some time off, but now it's time to get things moving again.
As I said in that comment, the next major steps for Tildes are going to be bringing in more people, along with more (and more varied) content. To help with that, I'm going to be working on some structural and functionality changes to make it easier for people to see the types of content they want, as well as avoid content they're not interested in.
So, I've just deployed the first piece of that: you can now ignore individual topics when you don't want to keep seeing them in your listings. Thanks yet again to repeated open-source contributor @what, who got this started a long time ago in a merge request that I was able to finish up and add a little more on top of.
Currently, the only thing that ignoring topics does is hide them from your listings, but I'm still thinking about some of the details and possible other effects and wanted to ask for input first:
- If you ignore a topic that you posted a comment in, should you no longer receive notifications about new replies to you in that topic? What about username mentions?
- Should users be able to ignore their own topics?
- Should ignored topics be hidden everywhere, or should there be exceptions? For example, if you do a search that matches ignored topics, should they show up in the results? If you're looking at the poster's user page, should ignored topics be shown?
- Is there anything else that ignoring a topic should (or should not) affect?
A listing of only topics you've ignored is also available through the sidebar on your user page as "Your ignored topics", in case you need to check on any of them or unignore one of them.
One other piece of this is that there's now an "Actions" dropdown available on every topic in a listing, underneath the vote button. This dropdown allows you to bookmark or ignore topics without having to go into their comments page first. I'm not totally certain about this yet, and will probably make some more adjustments related to it. In particular, it's pretty far off to the right on a wide desktop monitor, so I might try some other options after seeing how it feels to use on the live site.
Let me know if you have any feedback about these changes, or notice any issues. Hopefully there should be multiple more updates coming up over the next week or two.
And as usual, I've given everyone 10 invites, accessible on the invite page.
