- like Dynasoar was supposed to do ?
- because the orbit perigee is low and deep in the atmosphere ?
yes, which is not VLO. And while at perigee (low and deep in the atmosphere), it won't be taking data with sensors in the bay because the bay will be closed to protect them and the vehicle attitude will be driven by the manuver (plane change)

Wow, it took you one year (or is that more?) of constant thread interference to come to that... Without a word of excuse after being so combative in your denial...

How many posts of you rebuking your fellow posters have littered this thread?

I never changed my stance. I have been stating the same thing the whole time.
 
Nice to know it isn’t just Buran you look down on :)

At any rate—let me throw this into the mix.

They were very careful to show only a bit of the payload bay—but the aft section is what interests me.

Falcon Heavy gave this bird quite the thump…it may have a bit more hypergolics—but there may be another another way to give X-37 a bit more agility.

Byeman is right about wings not being of much use at its altitude.

What if it has a big tether?

Spin down for an orbital change—THEN use wings.

Not even a thruster puff visible. Just hang out…gradually feed out some line—then turn loose.

Falcon upper stage the counterweight…maybe like the one that broke up over Poland? It might be interesting to backtrack that.
 
I don’t particularly think we know at all what it can do, outside it’s unique ability to bring things back. I think it probably fills a huge role from a testing poiof view but I doubt it is something that is a practical operational platform. Certainly not at a force of only two. If it had a real operational mission, there would be more of them. Chances are it is exactly what the USAF says: a test play they use to do analysis where bringing back samples from long duration orbital missions is the goal.

Tethers, if they will ever make it to space (which I extremely highly doubt), would be for routine high volume operations into a fixed orbit, but not for on call missions like USAF on demand space-plane launches into all kinds of orbits with respect to inclination/perigee/apogee.
 
It is the only way I know of where you can get a relatively sharp re-direction.

Have enough in orbit—each spinning in a different direction—surely one in the mix is rotating towards where you want it.

I think the best use of the concept would be to reach bodies in space with a pretty steep inclination.

Coast in the general direction, deploy and spin.

Empty stage goes one way, while your payload is slung to a different inclination.

I *honestly* have absolutely no idea what you are referring to - are you envisaging retrograde orbits???
 
Gravity gradient might ruin my scheme.

Think of a lot of Molniya orbit tether bolas.

Let go on a descending node—then use wings

Swing low, sweet chariot…

Not feasible. Where is the counter masses kept?
Too restrictive. Too many would be required to cover all the orbits.

Again, another attempt to throw something at the wall to see if it sticks but not even hitting the wall.
Need to do some basic analysis first and stop basing ideas on your "feelings" because they are not well rounded. Learn that spaceflight and spaceflight history is not Huntsville centric. In the US, rocket science existed before Operation Paperclip.

Here is the problem. This doesn't work, telling other people to "think" like you. We don't have shared experiences* and with so little words, it doesn't describe what you are trying to convey. If you see in all the forums that you post (spam), they mostly go ignored because they don't understand them or you get a lot of thumbs down.

* this is described in the preceding post.
 
That is on you for not understanding orbital mechanics. I did not contradict myself once.
Do you work for Space Force ? Are you in the X-37 B program ? . This debate is going nowhere, so is it possible to come back on the X-37 B thread ?

Did you ask yourself to show me where I do fail in Orbital Mech?
Right here.

Nobody mentioned firing the thruster in the atmosphere but during coast-up and down leg from the apogee.

The thruster firing to lower the perigee into the atmosphere is done at apogee.

Firing "during coast-up and down leg from the apogee" doesn't change the perigee but rotates the orbit's major axis

As the poster choose to edit his older post instead of replying, I will complete here:
you are sticking to your college degree pictogram. You need to change the referencial to adhere to the core of the discussion.
NRO doesn't care much where the orbital equivalent axis is, but probably attach some importance to the overflown pattern during the perigee.
If you've changed that from Paris to Moscow in a timely, unpredictable fashion, you might have achieved something.

a. The NRO does care where the major axis of the orbit is, because that determines where the perigee is located*
b. it is not feasible as you state. It is not timely nor large.
c. It will take many orbits to make a significant change in the inclination.
d. the change is not west to east for "Paris to Moscow", but south to north.
e. no data can be taken during the perigee if it using aerodynamics to change the inclination.

* basic orbital mechanics.
 
As always, implying that others are imbeciles to pulp the plattitude of your vision on intricated problems:

Mscw 55° 45'
Paris 48° 51'
 
Excuse my ignorance on such things, but a couple of questions about the the picture of Earth taken by the X-37B.

1. Can it be calculated how far from Earth the picture was taken.
2. The elliptical orbit that it takes, is that pre programmed before flight ?
2. The resolution is amazing I am surprised how clear the picture looks as it was taken in Space, considering there is space dust between the two.

Thanks

That can really hurt—for years I was captivated by tank farm concepts:

-only to be belittled.

His words carry great weight..for he does have much experience.

But folks who worked on such concepts were bright too…they just never had Elon’s money.

Had I that type of wealth—I’d give it to the artists here…makers like Adam Savage…advocates…anything to keep thinkers from having to work two and three jobs until they’re ground into paste…like what has happened to me.

IIRC one of the Space Shuttles was scheduled to carry its' ET into a circular orbit to test delivery of an ET to Earth orbit in 1986 but then this idea was dropped in the wake of the Challenger disaster.
 
The tone of the one-vs-one discussion had become unacceptable !
Please calm down and return to sensible manners again !

1. Yes
2. the original elliptical orbit was "pre programmed" before flight because that was what the launch vehicle put it in. Subsequent maneuvers are commanded from the ground
3. There is no "space dust" that affects imaging in earth orbit. The X-37 is nearly at the same or lower altitude that weather satellites use.

You have done worse. You have made outrageous claims and accusations for decades without providing proof or data to support them and spamming them on multiple forums. You have accused military personnel of lying and being underhanded. You make inane claims that are discredited in one place and then still go and post them on other places.

Never was in the actual plans.
 
@Jemiba : hadn't I flagged this very one as lacking what you call sensible manners (beside of being a shameless lie) ?

I can still see it in the thread.
wrong again.
a. It was in the context of 2012 and it was about the propellant load and being launched into low earth orbits.
b. X-37 can't perform much aero maneuvering from low earth orbits.
c. the current orbit is useless for microsats
d. the point still stands. X-37 isn't a good platform for "responsive"deployment of micro sats.
