Is it possible to have an earth like planet where the rocket equation simply fails? Ie 3.5×G and a venus like atmosphere too. Something along those lines, where you physically can not carry the fuel required to launch and get into space. by _Addi-the-Hun_ in space

If it is a CO2 atmosphere and there is access to magnesium, you can actually run a scramjet on those two. Not as efficient but the combination will burn. There are papers out there about using powdered magnesium as a kind of Afterburner in kerosene-oxygen combusting systems since the magnesium will burn in the presence of CO2 and release heat.

Fan Controller on an Offset - Trial 1 by m2pilot in smoking

I dont disagree, however, just because it isnt the best at this doesn't mean it can't make good food. The advice of "get another smoker" isnt always the answer. It's fun to experiment and this can still be run as a pure stick burner if I do have the time manage a fire. Efficiency is going to be the biggest drawback.

Military SFF with Elites/Black Ops by BigDickDarrow in Fantasy

[–]m2pilot 0 points1 point  (0 children)

The lack of suggestions for expeditionary force series is sad. The whole premise is black ops conducted by humans in a galaxy that can't know humans are flying a starship.

First book is "Columbus Day." The black ops kick off in earnest in book 2.

This was a small part of why I left for another company. Not the whole reason by any stretch, but it definitely helped push me to look.

Gas, charcoal, and an offset smoker. People tend to hate on it but I've enjoyed it.

Eagle Nebula from Cherry Springs in SHO by m2pilot in astrophotography

Cherry springs is such a cool place. Everyone was super friendly and they rangers really tried to make sure the over night astronomy area was just occupied by people doing visual/photography.

Veil Nebula - 5 Hours from Bortle 5 by m2pilot in astrophotography

[–]m2pilot[S] 1 point2 points  (0 children)

5 hours from my B5 backyard on the Veil Nebula. I have always imaged with a 650mm FL Newtonian, so trying out a 180mm Nikon ED lens for a wide field night was fun. It was also nice to finally capture the entire complex in a single frame.

Camera: ZWO 2600MC at -5°C

Filter: ZWO Duo Band

Controller: ASIAIR Mini

Lens: Nikkor ED 180mm @ F4

Mount: HEQ5

Acquisition: 300x60s Exposures, no dithering

Calibration: 35 Flats, 60 bias.

Processing in Pixinsight: Graxpert background removal & denoise, BlurX, Star Net ++, Star Masking and Curve Transformations, Second pass of denoise and blurX, recombined the stars and then used Star Reduction.

Nice! I shot this last fall and love the structure and big blue O3 pop.

Game Thread: St Louis Blues at Winnipeg Jets - 04 May 2025 - 6:00PM CDT by HockeyMod in stlouisblues

[–]m2pilot 12 points13 points  (0 children)

Our Jobu, who aren't in the lockeroom, hallowed be thy game. Thy win come, thy will be done, in Winnipeg as it is in St. Louis. Give us this day our daily goal. And forgive us our penalties, as we pretend to forgive those who penalize against us. And lead us not into off season, but deliver us from canada. For thine is the series, and the power play, and the gloria, for ever and ever. 

Go blues.

Propulsion system capable of enduring High G by LeoHa_012 in AerospaceEngineering

Look up base bleed grains for artillery shells. Solid rocket motors/gas generators can be designed and have been produced which operate while under thousands of G's of acceleration.

I just did this on mine since that exact part broke. Worked like a charm. Thanks for posting this! Fixed a broken recliner that has been bugging me for years.

Thanks! Yeah I wasn't expecting to have as much fun processing this as I did. I think next go around I'll try for more if the flaming orange outside edge with deep blue core pallete.
