In 2010, Orbinaut JonnyBGoode posted the following comment in the thread “What are you reading?”: I'm reading Two Years Before the Mast, by Richard Henry Dana. A sci-fi adaptation of this book would be fascinating. It only took fourteen years, and I’m happy to grant JonnyBGoode’s wish. I (Mike...

Very cool. Can you reflect the Sun to a spot on Earth's nightside?

I have a reply to a comment made by JonnyBGoode some years ago. However, JonnyBGoode hasn't been on Orbiter Forum since January. If anyone knows how to contact JonnyBGoode and could pass the message that I would like to exchange a couple of comments, I'd appreciate it.

I'll suggest this one more time: In order for a user to edit the wiki, require the user be registered. Perhaps allow auto-registration for members of Orbiter Forum, along the lines of Orbit Hangar.

Is it feasible to use Orbiter Forum registrations to check on OrbiterWiki registrations? And then not allow anyone to create/edit an article unless they are registered in both places? That might be a way to cut down spam.

Does the new forum software allow the use of the MATH tag, as in F(Q) = -\frac{\mu\, m}{(Q-Q^*)^{2}} ? For instance, the page at https://www.orbiter-forum.com/threads/building-a-symplectic-numerical-integrator.32288/ used to be readable with the previous forum software.

SpaceX has given us a gift. Probably not very challenging for Orbinauts. https://iss-sim.spacex.com/

Idle thought: How far away from the sun could a black hole this size be and not be detected by its effects on outer planets' trajectories? For instance Alpha Centauri A/B add up to about 2 solar masses and are about 4.5 light years away; they presumably have no detectable effect on Pluto/Charon.

Do you know if this procedure (i.e., Wine) works on the latest version of MacOS (Catalina)?

This thread shows a need for more persistent guidance than Orbiter Forum can provide. I really hope the NASSP experts can help to develop some sort of training material. I would like to use it myself. I would like to suggest a home for any such material: the "Rocket Science For Amateurs"...

This is meant as a quick-start for people who want to improve OrbiterWiki, but don't have experience using a wiki. 1. Register as an OrbiterWiki user: https://www.orbiterwiki.org/index.php?title=Special:UserLogin&type=signup This isn't strictly necessary, but it might be useful to use the same...

Are you using the online version of Go Play In Space on Orbiter-Wiki? If so, feel free to make a new page for your script, and add a link to it from Chapter 2. We added GPIS to the wiki to allow the community to add updates and enhancements. This seems like a good example. Feel free to ask for...

I've downloaded at least four versions multiple times, certainly more than 20 downloads since 2009.

I can't claim to be much of a developer any more, but I've done a bit of Javascript work. I play "with" Orbiter at least once a week, which I enjoy even though I'm not very accomplished. I would like to try to use Javascript with the Orb::Connect add-on to develop web-based interfaces to...

Bravo! I haven't digested the lessons yet, but I applaud your effort. On the OrbiterWiki website, there is a section I have called "Rocket Science For Amateurs". You might consider adding a link to your tutorials on this page: https://www.orbiterwiki.org/wiki/Rocket_Science_For_Amateurs

Please note that the latest version of GPIS is a partially completed third edition (not the second edition you linked to). This great resource now resides at OrbiterWiki: https://www.orbiterwiki.org/wiki/Go_Play_In_Space The second edition was written for Orbiter 2006, and the third edition was...

I had my worst wreck ever (age 70) on Sep 10, and I'm still not fully recovered. The worst aspect is that I don't really know what happened, as I hit my head hard enough to lose consciousness. I was using the Cyclemeter app at the time, and it shows I was going downhill about 25 mph (40 kph), on...

Does anyone here know/surmise/guess/wish that the Crew Dragon or CST-100 Starliner could take a repair crew, tools and parts to service HST? Or perform other similar functions that were formerly done by Space Shuttle?

That's a long time in a seat. In 1977 I flew Sydney to LAX non-stop in a 747-SP. We were delayed on the ground while some sort of work was being done on the plane. Eventually, the captain made the announcement: "The mechanics are repairing one of the toilets. We're going to be in the air for 11...

This provides several dimensions. I don't know if it is enough for your purpose. https://www.hq.nasa.gov/alsj/LM04_Lunar_Module_ppLV1-17.pdf Please keep us informed of your progress!
