SpaceX Dragon Re-Entry Viewing

[ChrisC]

This post (and subsequent discussion thread) is intended to provide basic guidance on viewing the return of a Dragon capsule, whether Cargo Dragon or Crew Dragon.

*** UPDATE Summer 2025: splashdown activity has now moved to the Pacific / southern California, but this thread can still serve the purpose of describing Dragon viewability.  Much of the analysis below still holds, especially the timeline and the ascending  / descending node discussion.  It'll just need to be adjusted for the West Coast returns.  If you do that analysis, please post it as a comment and I'll eventually edit it into these earlier posts, as appropriate.  -ChrisC ***

Most Dragon capsule flights go to and from the International Space Station (ISS), which necessitates an orbital inclination of 51.6 degrees.  Since SpaceX supports nominal returns only to ocean splashdown locations around the Florida peninsula, this means that the Dragon will usually be approaching on a southeasterly track, OR a northeasterly track.  The southeasterly track will have the Dragon executing the final minutes of the (flame-y) re-entry across the southeastern US, typically over Tennessee, Alabama and Georgia.  The northeasterly track will put those final minutes over the Gulf Of Mexico.

To determine which of those tracks is being followed by a Dragon that has just left ISS, use an ISS tracker app to look up the ISS flyover that is happening around the splashdown time.  Because the Dragon will have pretty much the same orbit as the ISS (certainly the same inclination), the ISS will fly over Florida within minutes of the splashdown, even if the Dragon had departed a day or two earlier.  The direction that the ISS flies over Florida (NW-to-SE, or SW-to-NE) will match the Dragon's track.  However, most ISS tracker apps only show sightings in pre-dawn or evening skies, not in the middle of the day or middle of the night when ISS won't be visible anyway.  Therefore, it's better to use NASA's excellent Eyes On The Solar System simulator; search for ISS, then use the time controls to fast-forward to the splashdown time.

The rare Dragon flights that do not go to the ISS, such as the Inspiration 4 or Polaris Dawn missions, could approach on any easterly track, but usually they'll be in lower inclination orbits (e.g. 28.5 degrees) and thus will be approaching Florida from due west (heading due easterly).  This means those final minutes will happen over the Gulf or along the Gulf Coast (along the northern edge of the Gulf -- the LA / MS / AL coasts), depending on which of the seven zones has been targeted.

Obviously any re-entry over land has the potential to be visible to people on the ground.  Assuming clear skies, nighttime flyovers should be easy to spot -- you just need to look for the bright spot, with a glowing trail behind it, moving across the sky a bit faster than a jet.  Where in the sky depends on where you are, and which of the seven splashdown sites SpaceX is aiming at, but you may not know that ahead of time.  So it's best to scan the entire sky for those several minutes, especially if you think you'll be directly underneath it, because a small left or right crossrange variation by the capsule could put it on one side of the sky or the other for you.

Daytime flyovers are harder to spot due to the background sky, but with very clear skies, and some knowledge of which splashdown site they are targeting, you can know which way to look.

In general, your viewing location should be a spot where you can see as much sky as possible, but especially the southeastern sky.  LOOK UP and scan the ENTIRE sky, looking for a slow streak moving across the sky (likely from the northwest to southeast, per discussion above).  Even if you do spot it and it departs down below the southern horizon towards Florida, stick around for an extra two minutes because a sonic boom will "trail" the capsule.  You can visualize the sonic boom as the capsule dragging a cone behind it, and when that cone's intersection with the ground passes over your spot (on the ground), well after the capsule has passed overhead, you'll hear the boom.

Regardless of the exact track, a sonic boom will definitely be audible if the capsule has descended far enough into the atmosphere, typically within 1000 miles of the splashdown site.  So even if you have cloudy skies, you should be listening for the boom about 5-15 minutes before the planned splashdown time, depending on how far up-track you are from Florida.  the boom will likely sound like a distant thud, like a explosion far away, and typically generates attention on social media -- and even regular media.  ("Uhhh, did you hear that?")

Typical timeline, referenced against splashdown time:
S minus 51 minutes: deorbit burn starts
S - 37 minutes: deorbit burn completes
S - 15 minutes: entry interface (capsule's first encounter with atmosphere)
S - 13-14 minutes: fireball / streak across sky starts (~1200 miles up-track)
S - 6-9 minutes: fireball / streak across sky ends (near Florida)
S - 4 minutes: drogue parachutes deploy
S - 3 minutes: main parachutes deploy
S - 0 minutes: splashdown   79:30

NASA will typically announce the planned splashdown time.  You should then back that up by 10-15 minutes to estimate when the capsule will be flying over, then be outside and scanning the skies 5 minutes before that, especially if you are well up-track from Florida (e.g. in Tennessee, Louisiana, Mississippi, Alabama, or Georgia).  If you are even further up-track (Arkansas, Oklahoma, Missouri, Kansas, Nebraska, Colorado) you should go outside a couple minutes sooner.

Hi all ... As you can see above, I've written a reference post to explain to people how to see an reentering Dragon capsule.  I'm in north Georgia and have seen this zero times and heard it twice   I'll be outside tonight (early tomorrow) to try again, and this time I'll be noting the exact timing, so I can improve the writeup above.  (There's no need to comment on tonight's visibility for me personally; I'm following the Crew-7 thread and I'm aware of the track.)

If you observe this reentry, or any re-entry for that matter, please document the following:
A) which direction you were facing (e.g. southeast)
B) about how high up over the horizon it peaked (e.g. one hand-width with your fingers spread, two of them, etc.)
C) EXACTLY what time (to the second) you saw it -- beginning, peak height, and end
D) exact time you heard the sonic boom
E) where you were -- just the city / region is fine.

A few things other things that I could use help with:
- if anyone knows the entry interface time (yy above), let me know and I'll edit in (EDIT: done)
- I could also use an NSF-sourced graphic for the landing zones (the only one I found was a webp file, and this forum rejects that upload) (EDIT: done)
- I'd like to provide a graphic for a typical descending-node entry path to the Atlantic side of Florida (I used a FlightClub.IO graphic here that shows a Pensacola splashdown, and linked to the tweet in the text)  (EDIT: still needed)

Finally, if anyone is savvy enough to create some custom graphics to illustrate these entry paths and their visibility, go for it!  I link to several images in the text, but I'm sure some here can do better.

[Ron Lee]

I saw it on the original map timing from Colorado Springs, CO area.

Initially almost due north up about 5-10 degrees around 3:36:10 AM MDT then as it was passing northeast a visible trail...fading about 5 degrees elevation around azimuth 110 degrees at about 3:37:50 AM MDT.

Reddish tint.

Before it faded from view totally it was getting dimmer which logically seems to be because I was not looking at the heat shield area from the front like when I first saw it or even the side when it was passing to the northeast.  It might be better to the southeast (since I was west of the ground track) if I were in Arkansas but not closer to the beginning of the plasma phase from my location.

[ChrisC]

Thank you Ron!  Looking at a map, I'd say that you were about 165 miles off the forecasted ground track.  Would you say the peak altitude (over your horizon) was around 10 degrees?  And it's unlikely, but did you wait around to try to hear the sonic boom?

My own report:  I saw it!  From 200 miles away in Atlanta, I went to a spot with a perfect view of the southwest horizon (a neighborhood overlook) and saw the glowing trail about 4 degrees above the horizon.  It was right on schedule at 5:41am ET -- I was unable to note more accurate timing due to it happening so quickly.  Anyway, take that, NASA visibility graphic ... I do wish they would add another contour to those graphics for 5-10 degrees altitude; 5 degrees is totally visible if you just move to a decent spot, and as low as just 2 degrees is possible.

I waited a bit for the sonic boom, but then realized with cross-range distance of 200 miles, it would a) take 15 minutes to get to me and b) would have totally dissipated by then.  I do hope to eventually find out (in this thread) what's the farthest cross-range distance we should expect to hear the boom, and then I'll document it above.

[Ron Lee]

It may have been about 15 degrees but consider that approximate.  Around that time I was trying to video it and did not check a nearby star (in Cygnus?) to get the actual elevation.  I did not think to wait for a sonic boom.   Big mistake but I was excited to see it.  Next time will be better.  Currently I am trying to characterize the deorbit burn and propellant dump from Starlink 6-xx launches.

A key takeaway of my observation and probably yours is that the elevation estimate and times were close enough for most people to see it.  Allow for scanning left and right and up and down, plus being outside ten minutes or so to let your eyes adapt to the darkness, and looking several minutes early and late just in case, and people can see the next one.

What got me were the postings saying that splashdown was three minutes earlier than expected.  So I was looking perhaps five - seven minutes early.

[Bob Niland]

Rural, no yard light, near Abilene KS, just happened to need to be up at reentry time (making an airport run), and sky was pretty clear, so went out to see what might be seen.
A bright star-like spot appeared on schedule low in the NW sky, which turned into a larger, obviously reentering object, and made its way to the SE, leaving a glowing plasma trail, perhaps 25-30° above the horizon. I wasn't able to hang around long enough to see if there was a sonic boom.
The presentation was both brighter and faster than I expected, but that's based on never having previously watched a controlled spacecraft reentry, although I have seen many meteorites, a couple of skippers, and what might have been some retrograde space junk.
No effort was made to get photos or video, as this would have required figuring out how to override the auto-exposure and auto-white-balance on the phone, and some advance testing. Maybe next time.

[ChrisC]

Here is a collection of observations of the Crew-7 reentry from around the internet, sorted roughly uptrack to downtrack:

Colorado Springs: see comment above
video: reentry early this morning over southwest Nebraska
photo: capsule reentry early this morning from our hometown, Salina, KS
Abilene KS: see comment above
news report with video: Oklahomans could see SpaceX Crew-7 making re-entry early Tuesday morning (OKC?)
video: SpaceX Crew 7 on Dragon Endurance Reentering over Tulsa, OK
news report with video: Saw something in the sky overnight in Arkansas?
news report with video: Four State residents watch the re-entry of SpaceX Dragon capsule (Joplin MO)
video: Off I-10 in Alabama mile marker 44 looking west

If anyone has some suggestions for my writeup guidance above, let me know.  For the next reentry I'll polish up the formatting, splitting it into titled sections.  Eventually this should be good enough to be made into a sticky thread, like the how-to-see-a-launch threads.  See you all at the next one!

[ChrisC]

With the CRS-30 cargo mission coming to an end, we'll have another Dragon re-entry, but for now this appears to NOT be one that will be visible / audible to most* people.  (EDIT: yes, Ron's corner case is why I said "most" )  But here's a link to the CRS-30 thread; if there any visual reports there I'll copy them here.  EDIT: none.

If the CRS-30 splashdown is roughly 1:00 AM EDT on 30 April 2024, then that will be a southwest to northeast ground track.  If it is an Atlantic Ocean splashdown then far more people will have the opportunity to see it than if it goes to a Gulf of Mexico zone.

[Ron Lee]

People may be able to see it even if going to the Tampa or other Gulf of Mexico (GOM) sites.  A few years ago someone at Shell Point beach south of Tallahassee photographed the CRS-21 entry going to Tampa.   It was low but since it was dark it should be easy to see.  The same should apply to other GOM sites.

This is from the Shell Point beach for CRS-21 return:

[ChrisC]

Weeeellll with today's announcement that SpaceX will transition Dragon recovery operations to the West Coast (to minimize trunk debris threat), the days of these overland returns are now numbered

In the Crew-9 press conference, SpaceX's Sarah Walker said "we hope for [the transition to West Coast returns] to be complete shortly after Crew 9's return".  Looking at the manifest, that appears to mean we'll see four more of these:

Aug-Sep 2024: Crew-8 return
Oct 2024: CRS-31 return (launch expected Sep 2024)
Jan 2025: CRS-32 return (launch expected Dec 2024)
Feb-Mar 2025: Crew-9 return (launch expected Aug 2024)

She also said that there would be a fleet transition period when the fleet would be split across both coasts, so maybe we'll see more or less than those.

Obviously I hope one or more of these will be descending node entries that pass over CONUS where we can see and hear them!

Notes:
Apr 2025: CRS-33 return (launch expected Mar 2025)
Sep 2025: Crew-10 return (launch expected Feb 2025)

[ChrisC]

It looks like the CRS-31 entry will be a descending node entry, so coming in across the continental US.  They have been delaying the entry day-to-day for a few days now, but each time the undock is at around 1600 UTC, and I am assuming that deorbit is a couple hours later.  Here's that mission thread; watch for news of a) go for undock, b) which Florida site they are targeting and c) the expected splashdown time.   Once the splashdown time is announced, you can use the timeline that I documented above to determine when and where to look -- and listen!

This screenshot is from NASA Eyes, showing ISS ground track during Dragon entry, although it could be an orbit later.  FYI it's Pacific time on the graphic.

[ChrisC]

During CRS-31 undock coverage, NASA said that splashdown is scheduled for 1:39am ET Dec 17th, late Monday night / early Tuesday morning.  That's an ascending node pass, so no flyover of the continental US   See you back here in a couple months for the next try -- which could be the last chance!

EDIT: Correction!  The NASA PAO person misspoke!  Per multiple sources in the mission updates thread (linked above) it's actually a Dec 17th 1:39pm splashdown, which is a CONUS floyover ...

OK then, showtime again!  Here then are the milestone times, referenced to 1:39pm ET splashdown:
12:48pm ET / S minus 51 minutes: deorbit burn starts
1:02pm ET / S - 37 minutes: deorbit burn completes
1:24pm ET / S - 15 minutes: entry interface (capsule's first encounter with atmosphere)
1:25pm ET / S - 13-14 minutes: fireball / streak across sky starts (~1200 miles up-track)
1:30pm ET / S - 6-9 minutes: fireball / streak across sky ends (near Florida)
1:35pm ET / S - 4 minutes: drogue parachutes deploy
1:36pm ET / S - 3 minutes: main parachutes deploy
1:39pm ET / S - 0 minutes: splashdown

[ChrisC]

(from the CRS-31 thread)

I looked with binoculars from about 11:23:15 - 11:29:45 AM MST.  I had a small area of mostly blue sky to the north to north-northeast.  I saw nothing.

Thanks for the report.  I also tried, but had solid cloud cover during that time period.  (Sunny before and after!)  I stood around listening for the thud, in case the flight path was right overhead, but heard nothing.  Had lots of truck traffic at the location I was at, so that could have masked it.  Both visually and audibly obscured!

For the record, this one ended up near Panama City, and did splash down at 1839 UTC.

Two more chances remaining, maybe.  Could just be one!

[ChrisC]

Per Gerst in the Crew-10 pre-launch briefing, the Crew-9 return coming up in a few days will likely be the final chance for a Florida crew return.  SpaceX has taken their two teams that previously operated in the Florida waters (one team on each side of the peninsula) and moved one of them to the Pacific.  The team remaining in Florida is now in the Gulf and supporting landing sites on that side only.  So now for this return (and only this return?) SpaceX will have both Florida and California options.  This Crew-9 return may be the very last one that goes over the continental US, and that only if it's a descending node return, as described at length above.

Per Sarah in the post-launch presser, the plan was stated slightly differently.  The Crew-9 Dragon WILL return to the Gulf waters west of Florida, so I guess what Bill was referring to was that California was provisionally ready to go, but really would only be targeted in a contingency situation.  Further Sarah said that after the Crew-9 return (to the Gulf), "we'll have a few [cargo Dragon] missions land in the west coast before Crew-10 comes there."  Finally, it sounded like SpaceX is NOT going to move the second team from Florida to California, after this Crew-9 return, so they'll just have the single team in California which I thought was odd at first but they do have much fewer splashdown sites (three) to support out west.  Plus perhaps they want to keep a team in Florida for launch abort ops.

So this Crew-9 return will indeed be the final one that might reenter over the continental US (CONUS).  Pay attention to the Crew-9 reentry news (in the NSF thread for that mission), because this will likely be the last chance for most Americans to see (and hear!) a spacecraft returning from space.  The targeted landing time will tell us if it's ascending node (flying in over Mexico and Gulf) or descending node (flying in over CONUS).

The next one after Crew-9 would be some time after Starship starts up regular orbital ops in a year or three, and even those will only fly over CONUS if they a) go to an inclined orbit and b) do a descending node entry.  I believe we have yet to hear where Dream Chaser will land, but that's another possibility.

[ChrisC]

I have updated my post above with information provided during the post-launch presser.

Per the first hazard notice for mariners, the current earliest splashdown times are around March 18th 6pm ET and March 19th 2:30am ET.  I believe they're already said NET 19th, so those particular splashdown times aren't happening, but this gives us a first look at the general time of day.  I believe the first one (6pm) would be ascending (boo) and the second one (2:30am) would be descending (yay).  Feel free to check me though and correct if I've got it backwards.

[ChrisC]

Well, they are going through the hatch closure and undock prep checklists, so this may happen on the 18th after all (so much for NET 19th).  From the NASA press release seen in the Crew-9 thread I linked to above:

5:11 p.m. – Deorbit burn (time is approximate)
5:57 p.m. – Splashdown (time is approximate)

So here's the expected timeline for a Tuesday 5:57pm ET splashdown, based on the learnings earlier in this thread:
5:06pm ET / S minus 51 minutes: deorbit burn starts
5:20pm ET / S - 37 minutes: deorbit burn completes
5:42pm ET / S - 15 minutes: entry interface (capsule's first encounter with atmosphere)
5:43pm ET / S - 13-14 minutes: fireball / streak across sky starts (~1200 miles up-track)
5:48pm ET / S - 6-9 minutes: fireball / streak across sky ends (near Florida)
5:53pm ET / S - 4 minutes: drogue parachutes deploy
5:54pm ET / S - 3 minutes: main parachutes deploy
5:57pm ET / S - 0 minutes: splashdown

Screenshot is from NASA Eyes, showing the ISS groundtrack and timing.  After undock, the Dragon typically drops down to lower / faster orbits, so will lead the ISS, so this fits.

[sdsds]

Asking for a friend: where would be the best spot (on land) to watch it streak across the sky?

[sdsds]

So if entry starts of Monterey would Big Sur be a reasonable viewing spot?

[catdlr]

So if entry starts of Monterey would Big Sur be a reasonable viewing spot?

Yes, directly overhead and inland.

[Launch Alert] Reentry Seen (and Heard)
http://mailman.qth.net/pipermail/launch-alert/2025-May/001901.html

Last night's (May 24) return of a Dragon cargo ship from orbit was seen and heard as it headed for splashdown in the Pacific west of Camp Pendleton. The following are comments from Launch Alert readers:

Wendell W.
Grover Beach, Calif.

"Fantastic viewing of the Dragon reentry tonight from the California Coastal Trail at Grover Beach. Saw it coming directly toward us from over San Luis Obispo and Pismo Beach. Heat shield glowing reddish with a VERY long white plasma wake. Very fast and directly overhead and south toward Vandenberg where the wake looked to end abruptly. Double sonic boom about that time was great too."

Brad T.

"It came a few minutes earlier than he predicted, but pretty close. Alas, it means my gear wasn't set up, but we got a handheld video."

Mike and Sue D.
Cambria, Calif.

"It was perfect timing over Cambria. Thank you. Great to see."

Zach R.

"Would not have known anything about the capsule splashdown tonight if not for your email earlier today. Was able to share an incredible moment and view with my son so thank you to everyone for making this event known. Incredible views tonight on this from my mountain home."

Marc
San Diego, Calif.

"I did not expect to see anything at all.
I was outside to our driveway more to see if I could hear sonic booms which I did not.
Saw about 45 seconds until it faded. I would not be surprised if it was visible even in Mexico. So if I saw it certainly LA would be no problem."

Jonathan F.
Tustin, Calif.

"Sure didn't see anything here in Tustin as predicted but I did hear an impressive double sonic boom at 10:40 or so, felt it actually as well. That or something big blew up around here..."

[ChrisC]

EDIT: threads now merged.  Thanks Tony!  Original comment follows:

I just came across these May 25th posts in this new thread that was then pinned.  LOL I created an incredibly elaborate and informative thread about Dragon reentry viewing, and then couldn't get it pinned.  Someone else creates a similar thread asking the basic question, there's a couple brief answers, and THAT one gets pinned?  Yuk yuk

Hi guys! (waves) ... I'll ask for this new thread's handful of posts to get merged into the existing thread:

https://forum.nasaspaceflight.com/index.php?topic=60517.0

and for that thread to be pinned.  That thread started out as being about Florida returns, of course, but absolutely can pivot to California returns.  If you are reading this within a longer thread with lots of timeline data and images etc., then that merge has been completed!

Giving this thread a bump (yes I know it's "pinned") since we have a Dragon return coming up that's higher profile than usual.

If anyone has any West Coast viewing information, including timing and visibility information like I figured out for Florida returns and posted in the first page of this thread, let's hear it!  I saw one from 200 miles away ...

I live over there. All landing spots are over the horizon and can't be seen. Depending on the reentry track, if it's a southern node (coming down from the north), it will definitely be visible along its entire reentry path down the coast from the Scott Manley area in the South Bay to Los Angeles, where I am, if it's dark. If it's a northern node (coming up from the south), then nothing. The Entry Node will be announced by either NASA or SpaceX. They haven't yet.

Good, the current weather is clear, but that could change in a couple of days.  I'll post the weather on the flight thread.  The ground track will be posted here when SpaceX make it available
