Re: Satellites : general discussion and musings
Then determine the energy required to maintain orbit At the escape velocity, in vacuum, this energy is zero. It is school physics: only Newton laws are needed. and transmit a signal. This energy requirement would excede that available to the communications or gps satellite, making the whole illusio...

Re: Satellites : general discussion and musings
..Supporters of continued and improved LORAN operation note that LORAN uses a strong signal , which is difficult to jam A strange comment, because if GPS was truly "satellite-based", it would be very difficult to jam that too! What exactly is strange? That ground antennas (powered, if nee...

Re: Satellites : general discussion and musings
The greatest altitude ever achieved by any man-made object is just 50km, and that was only an unmanned gas-filled polyethlene balloon. As you call it unmanned, you were not there for sure. So why do you think it's true? What if someone claim no balloon ever lifted higher than 40 km? What sources do...

Re: Re:
Well.. you are talking about shortwave radio wave propagation (just 2MHz or so) whereas the fraudsters' "satellite" communications (in truth just sky-wave propagation) are transmitted on frequencies in excess of 10GHz. Propagation properties of radio waves from two opposite ends of the sp...

Re: MARS & the Curiosity Rover - NASA's latest hoax?
Huh? AM and FM radio stations use transmitters 5 times more powerful than NASA's? I thought this was a typo or something, so I looked up what sort of AM radio transmitters are available on the marketplace. I quickly found this 100kW model: http://www.bdcast.com/products/details/high-power-am/4mx-10...

Re: Re:
if we suppose for a little moment that Astra satellites really exist, I'm too old for believing in fairytales, Dmitry ! Alas, geostationary communication satellites do not exist. All communications attributed to "satellites" are simply radio waves propagated by refraction from the ionosph...

Re: MARS & the Curiosity Rover - NASA's latest hoax?
As the mass of the MSL is 3 690 kg you need a mean braking (drag) force of 21.62*3 690 = 79 756 N acting on the space ship during 254 seconds. 79 756 N is quite a big force (about 8.1 tons of mass on earth) and I doubt very much that friction can apply it on the MSL spaceship for 254 seconds. I dou...

Re: MARS & the Curiosity Rover - NASA's latest hoax?
If I am the first person with a cell phone in my town, don't I need a transmitter mast to call people out of town or anywhere in fact? If your cell phone is too weak to reach the neighbour town's masts AND people you want to call are connected to the same telephony network -- yes, you need it. What...

Re: MARS & the Curiosity Rover - NASA's latest hoax?
Thanks for your comments. The MSL deceleration in the Mars atmosphere is no doubt non-constant as the atmosphere is getting denser the lower you get and is influenced by the fact that the friction force is not all friction but also due to turbulence around the space ship that varies with speed of s...

Re: MARS & the Curiosity Rover - NASA's latest hoax?
So if I had a mobile phone on Mars, the person I'm calling on Earth would have to wait 40 minutes for it to ring? If you try to use a conventional mobile phone, I think, nothing on Earth will ring ever. For a special space phone, the minimum delay will be N * 13.5 min depending on the protocol used...
