I think Matt was speaking of taking pictures at any location during nighttime. But, it would still require a long exposure to get stars to show up decently.

And the current generation forgets that Ceres and a few other bodies discovered in the early 19th century were considered planets until they realized that there were many in the same vicinity between Mars and Jupiter. Should Ceres also be considered a planet? What about those objects discovered...

There have been a number of Starlink launches where many satellites are orbited in one launch. You are probably seeing them for some period of time after launch. They will look just that, a bunch of ducks in a row. Eventually, the orbits will disburse.

I’ve often thought “What about all the material that vaporizes in the atmosphere, now we have many elements and compounds as vapors in what we’re breathing that was not intended to be there. Early in the Shuttle program, it was noted that they have found micro spheres of aluminum oxide in the...

Ah, I realized that the inclination is not in reference to the star’s equator, but, to the Earth’s line of site. Naturally, a lower inclination would not allow for occultation, it would pass above or below. I imagine that eccentricity would be limited, at very high eccentricities, allowing for a...

Problem is, that if the Earth were to spin fast enough to throw off a moon-size blob because that area reached escape velocity, as the blob ascends, the escape velocity decreases with altitude, the blob continues to ascend to never return. There is nothing to slow it down to orbital speed from...

I understand that Blue Origin’s New Glenn will also burn methane.

For future, any Star Trek, or Star Wars, Star Trek being my favorite. For current or near current, Apollo 13 the best, The Martian right up there.

That, too.

Good until they smash a screen or trash a cable!🫣

Hopefully, since the panels are on the side, that it can get a wee bit of power from sunlight reflected from the ground.

Sorta like guessing the size and shape of a vast forest from the viewpoint of a sparrow living on one branch of one tree.

The light source is likely the Sun, and any additional is likely sunlight reflected from parts of the spacecraft. Streaks may be camera artifacts, the larger spot is probably the tip of something on the spacecraft, the remainder of that in shadow. The faint white spot may be a star. -

I wonder if this would have an adverse effect on pilots, highly reflective surfaces blinding those in the air.

If this stuff is durable as a road surface, we could just paint this stuff on blacktop and concrete surfaces.
