I was joking, the earth is a spheroid for as far as I know.

Obviously you have not red and been enlightened by the Flat Earth Society FAQ. We shall see the light and know the truth that is the flat earth.

Flying the XR2 upside down to use inverse lift to keep me in the atmosphere I can achieve about Mach 46.5 at 70.2km altitude (cheating myself some fuel every now and then to achieve that speed) without skipping out of the atmosphere or melting the XR2. The nose tip gives a temp of 2500...

hey, at least it hit its target

What I'm seeing is the F9 1st stage tipping over and exploding? Did it land upright at first?

I would seem rather incredible if falling leaves would significantly affect the orbital characteristics of active satellites.

I'm gobsmacked that Orbiter is in the ESA credits :thumbup:

Other maybe than that yes, I have difficulty understanding things that are so highly theoretical without a physical reference frame or rather I can not trust something to be true without experimentally being able to verify it or reading through someone elses experiment. Most of the literature on...

Is there some literature detailing the experiments that tested the propositions of Special Relativity?

My question still remains then, how accurately do we really know the speed of light? I've already explained that I think that the observers point along earths orbits contributes a potential inaccuracy up to 30km/s and ~0.4km/s from earth's rotation.

Hi all, I've been wondering over the last couple days over the speed of light and what reference frame it is based on. Officially (ie. on Google/Wiki) the speed of light is 299,792,458 m/s. The problem I haven't found an answer for yet is what that is in reference to? Is in reference to the...

the XR2 is pretty easy to control, once in flight activate attitude autopilot with ctrl+L (or use the button on screen), then use numpad to control pitch and bank (and you still have manual control of yaw.) till you reach orbit. You can control pitch in smaller increments with alt. Learning the...

if they got out on chutes there is good chance that they are ok I think.

I've made a little video (7m 38s) of me putting the default DG into orbit: https://www.youtube.com/watch?v=NfLh9aKfVoM&list=UUlyaOcai3QxX45lFEoOvBWA I think key is to monitor your DNP from the surface MFD (Shift+F1 & Shift+S) and putting your trim all the way up while using ROT KILL (numpad 5)...

is there a full footage from when the comet went past its perigee @ mars? I can't find it anywhere. Is it in the private domain and if it isn't, is it going to be in the public domain? atm I only have a few pictures.
