Warning, if you make it shorter, you've got this: from here, pass x to the left and MrM1-M0 to the right, changing the signs: Mrx - x = M0-MrM1 then (Mr-1)x = M0-MrM1 then x = (M0-MrM1)/(Mr-1) (there was a mistake here)

Thank you so much for the pictures, the pre-last one is just amazing: a full C-17 for a small canister and the whole team. Great! Nice operation.

Also, @Urwumpe put in the shoutbox some very interesting material (IMO) about a huge modular wheel station: https://www.nasa.gov/sites/default/files/files/Longman_2013_PhI_Tensegrity.pdf Yesterday at 9:33 PM Urwumpe: Interesting paper. A toroid space station, that can be initially deployed with...

With D = 6 inches = 0.15m, we've got an affordable telescope that could even be integrated in a Delta Glider (the Arrow Freighter could easily get a 1m telescope, 7 times better resolution). Then, the angular resolution in visible light is lambda/D = 550E-9/0.15 = 3.7E-6 [rad] = 3.7E-6 * 180 /...

Whatever the CMOS pixel size, whatever the image processing or stacking. Dura Lex Difractionis, Sed Lex Difractionis ==> If you can "model" (i.e. assume) a telescope on Earth with an aperture D (in meters), the resolution of your telescope CANNOT be better than lambda/D in radians, with lambda...

could see an exoplanet? :alien: 0.0001° = 0.36 arcsec.... Proxima Centauri b orbits at 0.037 arcsec from its star, i.e. 1/10 of the FoV :) this MFD isn't anymore a "cheap" telescope, but fun to think at it

By the way, is there a potential to design retroreflectors in Orbiter? We can already design light emission, but retroflector is another story: emitting only when the observer points a light to it. I guess it would request coupling the observer's light and the observed object. Could help see...

I would love to see standard (habitable) modules of a wheel station brought by Flacon Heavy to Lunar orbit that could be assembled there, hence with auto-docking systems to one another, eventually forming the wheel. The size and rotation would recreate 1G at the perimeter, it could be seen from...

Not sure I understand the plot... does it mean that the orbit will still be "highly" elliptical? (150 perilune to 550+ km apolune....)... or does it read from right to left in remaining time?

That's very interesting!! Maybe also with orbiter it could be "simple" to assess the impact velocity and tell whether some debris could be visible from Moon orbit by another orbiter (beyond some velocity I guess only a crater could be visible....). Naive thoughts?

British cynical humor, :hum: Here is the news by Roscosmos / Telegram :eek: On August 19, in accordance with the flight program of the Luna-25 spacecraft, it was planned to issue an impulse for the formation of its pre-launch elliptical orbit. At about 14:57 Moscow time, communication with the...

if the maneuver was to decrease the perilune, then it's bad...

Really really nice!!! Apparently the astronaut must have been sick due to low gravity and hard landing... and she put her sweatshirt inside-out :D (NASA logo) ok... :rolleyes: ... really nice, as said.

Additionnally, be warned that NET4 is not supported after VS2019 (maybe no need for some compil) and the download of VS2019 is still possible but hidden behind deep layers of MS marketing to promote the last VS version. At least, that's my latest experience at setting up VS for Orbiter 2016 add-ons

Surprising!!! and I would be very interested in that. Even worse, after compiling my add-ons with VS 2019, my complied modules could not be run with the runtime only and the fix I found was to have VS 2019 installed in windows (10GB more for a non-specialized user... a pity). I requested the...

I understand that you extracted these bodies from available other kernels and made a new one called "orbiter.bsp", didn't you? It seems to cover all these bodies, indeed, but when were ithe source kernels published last? (as we experienced some shifts wrt Jupiter's moons, for instance). Probably...

In the launchpad > Visual effects, section "Celestial sphere" and in > Parameters, section "Stars", you can play with some enhancement of the sky and even see the Milky Way for instance. I'm using Visible (DSS2/Wikisky) with intensity 0.20, with App.magnitude of stars up to 7. for min.brightness...

too bad, I'll have to add it to my own to-do-list... :) but nice tries "realism" is not a must, as long as physics is still behind, imagine new raw materials, etc... from @Max-Q 's link, radius 100m yields 1G with 3RPM... but, indeed, heavy load on the structures... I think we can have...

As a modular approach (apparently), that's a nice wheel station, that could even be larger, couldn't it?. 2 questions: with this size, what should be the rotation to provide 1G at the periphery? as you must dock at the center, would it be do-able to add an animation - like an automated rail or...

I don't know who maintains this list (maybe some bot?) but that's a valuable resource that I didn't know!! may he/she/it be thanked for it :)
