That's just the planned orbital path, 2nd stage and the Roadster are still relatively near Earth.
Just the planned orbital path, the 2nd Stage and Payload (Roadster) are in the red circle still near earth.
With Orbital Mechanics once you make a burn (Mars Insertion Burn was only 1 min or so around 10pm EST last night) and stop it you would be taking in past tense. The burn is over so the path it will take is set. All he is talking about is the orbital path which was set during the mars injection burn
Correct
Same thing in Kerbal Space Program (really fun computer game another Anon mentioned a couple comments ago.
And more-so, the orbital period for that orbit to go around the Sun once is around 830 some days. Next closest approach to Earth (by a couple million miles) will be in about 12-13 years.
It was NEVER going to Mars. Actually going to mars requires a shit-ton more fuel to slow down from interplanetary speeds for a good insertion burn. Launching to mars orbit and even asteroid belt orbit around the sun takes far far less.
BIG FACEPALM
It's not a hoax, or some crazy physics shit. Image shows a normal orbital path after an insertion burn. The damn orbital period is 827 some days to orbit the sun once. Next period in time with it will be closest to earth again will be 12-13 years from now.
10:46 was after the Mars Insertion burn which was done obviously near earth. That burn was only 1 min or so long. They overshot (probably burning for an extra 30secs or so). It will takes months to arrive at that location. It will also take about 827 some days to orbit the sun once. It will be closest to earth again in 12-13 some years.
STOP WITH THE SIMPLE MATH WHEN YOU KNOW NOTHING ABOUT ORBITAL MECHANICS
Doesn't have anything, I was just responding to another Anon. Don't bark up my ass for responding to someone's statement.
He never tweeted it reached the asteroid belt. Just the orbit, orbit is pre-determined after the insertion burn. So he can talk in past tense about the orbital path reaching the belt because it did. The 2nd stage/Roadster will arrive months from now
From the given perihelion and aphelion, here is Tesla Roadsters velocity:
Relative to Earth Relative to Sun
17840 m/s 47626 m/s
64224 kph 171454 kph
39960 mph 106536 mph
11.1 miles/s 29.6 miles/s
Based on the numbers in Elon's picture:
Apohelion: 2.61 AU (Ra)
Perihelion: 0.98 AU (Rp)
a: semi-major axis
e: eccentricity
Ra=a(1+e) ; Ra/(1+e) = a
Rp=a(1-e) ; Rp/(1-e) = a
Ra(1+e) = Rp(1-e) ; solve for e, e = 0.454039
Solve for a, a = 1.795 AU
Orbital period T = 2pi * sqrt(a3 / u_sun) = 878.4 days.
Assuming the perihelion ends up coming back to roughly the same spot where the earth is in 5 roadster orbits, it might come back within a few million miles in 12 earth years if its orbit doesn't get perturbed too greatly, but we need to know the inclination and some other parameters to get a complete ephemeris to run a simulation (probably including Jupiter) to see where it'll actually end up.
In the 4 or so hr livestream of the car rotating around earth before the Mars Insertion burn you can see the Moon a couple times. Many people in some diff SpaceX subs pointed that out as well. But not here to debate those topics in this thread. Don't want to derail too much from the main Q points.
I didn't spot it myself. Other spacefags on plebbit pointed it out. Screenshot had the moon pretty bright and the lens from the camera showed multiple lens flares from the sun reflecting off the surface. If it happened to be just lens flares or some artifact from the camera so be it. Not here to discuss moon theories and such
Satellites compared to the ISS are small, so if you aren't going to see the ISS good luck finding a Sat during the livestream. Space is big obviously, just as big in LEO (Low Earth Orbit). You would need to be really fucking close (I'm guessing less then 100km) to even see a little reflection off the ISS let alone a much smaller satellite.
I also don't know why type of camera or lens was used. I'm not a photographer or an expert on that by any means but you need certain camera/lens to be able to catch faint dots of light like that.
That's my guess about why you can't see those objects.
I just replied to those points in a different comment, here is what I posted:
