Starship Flight 15 Launches Nov. 13 — Here's How to Spot It

"It certainly will be visible in twilight hours. It should be very bright, considerably brighter than the Starlink satellites due to its size," professor James Osborn of Durham University told Space.com. "Where and when is a bit more tricky."

The best viewing windows are the 90 minutes after sunset on Nov. 13 and before sunrise on Nov. 14, when the spacecraft catch sunlight while drifting through twilight. Ship and its satellites will initially look like a string of bright, evenly spaced lights, with Ship likely the standout. Osborn cautioned, though, that the lack of publicly available data makes precise predictions hard.

The viewing zone is broad. During its 14 orbits over 22 hours, the spacecraft stays between 30.5 degrees north and south of the equator.

"So it will be best viewed between those latitudes, and then lower in the sky up to latitudes of 40 N and 40 S. That's pretty much the whole of the contiguous U.S.," Massey said.

What will it look like?

Space.com skywatching columnist and veteran meteorologist Joe Rao described what naked-eye observers might expect as Ship drifts silently through the autumn sky.

"When it passes overhead, it will look like a bright, fast-moving star crossing the sky — similar to the International Space Station, but potentially even brighter depending on its orientation," Rao said. "The Starlink V3 satellites are much smaller, so not as bright, perhaps ranging anywhere from 2nd to 4th magnitude, depending on the angle of illumination with reflected light from the sun."

Magnitude is the scale astronomers use to measure night-sky brightness — the lower the number, the brighter the object. Under ideal dark conditions, the unaided eye can detect objects around magnitude +6.5; Venus currently shines at -4.41.

Rao added that the Starlink train will likely fall further behind Ship as the 22-hour mission goes on, and the train itself will stretch out. "For locations where it will make a high arc across the sky, the Starship should be visible for at least a few minutes, although because it is orbiting at a lower altitude (170 miles/275 km) compared to the ISS, it probably will appear to move somewhat faster," he said.

That's low even by orbital standards — the ISS orbits roughly 250 miles up, so Ship will cross the sky noticeably quicker.

How can you track Starship after launch?

Several free resources can help you follow Ship and the newly deployed Starlink V3 satellites after launch:

• Heavens-Above
• Star Dash
• Orbital Radar
• Find Starlink

All of this depends on the launch going to plan, of course — test flights of an experimental rocket can slip, scrub or end early. But if Flight 15 sticks its script, most of the lower 48 states gets a rare chance to watch a 171-foot spacecraft trace a line across the twilight sky.
