Another awesome Space Coast night launch! SpaceX launched a Sirius XM Radio satellite into orbit. The SXM-8 was sent to replace SXM-7, launched last year. SXM-7, also launched by SpaceX, was successfully placed into orbit but was D.O.A. and was unable to be revived. SpaceX successfully placed SXM-8 into orbit. It will be several days until the health of SXM-8 will be known.
Usually when I do a streak photo of a night launch, I like to get the arc. As a rocket launches, it ascends into the sky. When it reaches altitude it levels off and continues to fly. Due to the curvature of the earth, from the ground, it almost looks like the rocket is coming back down. During a long exposure night photo, you are actually photographing the light from the rocket engines. This makes a streak in the sky, due to the curvature of the earth the streak makes an arc in the sky.
Now, to work out the exposure. A typical rocket takes 3-3.5 minutes to reach orbit. I usually use 3 minutes for my shutter speed for testing my exposure. In real time I will hold the shutter open until I can no longer see the rocket. To work out the f-stop, I do a series of test exposures at different f-stops. The amount of lighting on the foreground will determine the proper f-stop. When the foreground is exposed properly with a 3 minute shutter speed, that’s the correct f-stop. In this case it was f-16.
This launch had two issues. The first was trajectory, the rocket was flying due east. From Titusville it was flying directly away from the camera. So no arc, it would look like it was just going straight up. The second issue was cloud cover. Shortly after launch the rocket was going to go behind the clouds. Once again no arc, no matter what direction it was flying. Normally I use the widest angle lens I have, my 24-70mm at 24mm. Knowing the rocket was going to go behind the clouds shortly after launch, I zoomed in to compress the scene. This sort of, solved both issues to make a pleasing image. Also because the rocket was going behind the clouds, it wouldn’t be visible for the full 3 minutes. To make the exposure correct I still needed to keep the shutter open for the full 3 minutes. In this case I actually opened the shutter 1 minute before liftoff.
I photographed this launch from the newly renovated Rotary Riverside Park along US 1 in Titusville. The park had been destroyed by a hurricane a few years ago. It had just been reopened a few days earlier.
SpaceX launched another flock of 60 Starlink broadband internet satellites. I stayed close to home this time. I took this photo from my driveway in Titusville Florida.

First, the rocket launch was a total success. It was my image of the launch that was a failure. The other night Space X launched a Falcon 9 rocket on a resupply mission to the ISS. Night launches not only make great photographs, but they are really cool to watch. You can watch the glow of the rocket engine all of the way into space. Photographing a night launch is very tricky. You only get one shot, literally one image. So if everything doesn’t come together, the photo is a failure. Photographers always like to share our amazing images that were a success. I think it’s also important to talk about the failures.
When you photograph a rocket launch at night, the idea is to use a long exposure. As the rocket climbs into the sky during the exposure, it makes a light trail through the image. It makes a really nice image. Using the cameras bulb mode, when the rocket ignites (trust me, at night, there is no question that the rocket has ignited) you open the shutter. As the rocket rises into the sky, you keep the shutter open until it goes out of sight, approximately 3 minutes. When it works, it’s awesome, when it doesn’t it’s not. This time it didn’t work.
The other part of the image is location, location, location. The rocket launch is really pretty on its own. To make the image even more interesting, I like to add something else. This can be either a silhouette of something interesting or something interesting that is illuminated added into the frame. A reflection would be great as well. For this launch I chose the Exploration Tower in Port Canaveral, Florida. It is several miles south of the launch pad. The tower is a unique structure that was designed to look like a sail. At night the tower is illuminated and stands out really well in the night sky. The tower is also lined up with the launch pad. If you line everything up properly the rocket makes an arc over the top of the tower. I looked up some launch photos from this location, so I knew where the rocket would be in relationship to the building.
The next hurtle is getting the correct exposure. The shutter speed is fixed at the duration of the flight of the rocket, approximately 3 minutes. This makes the aperture very important. Rocket engines at night are very bright. If your aperture is open too far the rocket will overexpose. If your aperture is too small the rocket will be underexposed. Typically I end up at f18, this works most of the time, especially for the rocket with a silhouetted foreground. When you add an illuminated subject this makes things more difficult. A 3 minute exposure will severely overexpose an illuminated subject. To overcome this I used a neutral density filter. After testing different apertures with a 3 minute exposure, I found that f11 and a 4 stop ND filter at ISO 100 exposed the tower properly. The rocket exposure would fall where it may. The important thing was to expose the tower correctly.
So what went wrong? I don’t really know for sure. To get the 3 minute exposure I needed to use the bulb setting. I made many test images that all worked perfectly. I was there with a fellow photographer friend, Chris. We also wanted to photograph the tower before the launch, so we arrived pretty early so we had some time to do that. After my final test shot, I didn’t touch my camera until the launch. We finished up a little early, so quite a bit of time passed between my last test and the launch. We had been talking with another photographer from Orlando. I think maybe something timed out and I was no longer in bulb mode or my remote switch may have timed out, I don’t know. The viewfinder indicated that I was still in bulb mode, but the shutter would open and immediately close. It was very frustrating to say the least. Several colorful words were going through my head. By the time I corrected the situation the rocket was over half way through its flight. At about 8 minutes before the launch, a voice in my head was telling me to do another test photo, I didn’t. If I had, I would have encountered and corrected the problem during the test. I will be doing that in the future. Once I got the shutter to stay open, I left it open for approximately 3 minutes. The rocket was still going so even though I wasn’t going to get the whole light trail. I wanted to see how my image would have looked if everything had gone as planned. The rocket flew right where I wanted it to be and the tower was properly exposed. I will need to try this one again.
I also made a mistake when I was photographing the tower before the launch. It makes me crazy because I have made the same mistake several times in the past. I am not a very technically disciplined photographer. I tend to concentrate more on the subject and composition. Sometimes I get so wrapped up in that and I forget about the technical side of things. Apparently the last time I used my camera I was using ISO 800. I never checked the ISO, I wanted to be using ISO 100. Once again my little voice was asking me, “Roy, why are your shutter speeds so fast?” I should have been smoothing out the water more. I was almost done when I realized what I had done. ISO 800 probably helped the shadow areas. If I would have used ISO 100 I would have been able to control the highlights better and I would have smoothed out the water with a slower shutter speed. I always promise myself that I will remember to check the ISO, and/or remember to return it to ISO 100, but every once in a while I forget. These are some of the things that make photography a challenge.
Last night SpaceX launched a Falcon Heavy rocket from Kennedy Space Center in Florida. A normal Falcon 9 rocket has, 9 powerful Merlin rocket engines. A Falcon Heavy is three Falcon 9 rockets strapped together! SpaceX has been continually tweaking it’s Merlin engines. This Falcon Heavy is the most powerful rocket flying today. Boy was it powerful! This rocket was Space Shuttle loud. You could hear the rumble building as it got closer and closer. The sound started to reverberate off of the buildings, then the sound waves hit, you could hear and feel the rumble! It was awesome! The reason for all of that power, the Falcon Heavy was carrying 24 assorted satellites into space. Advances in technology have made it possible to build smaller satellites. This allows rockets to carry multiple satellites into space on the same rocket. Not only is this more profitable for companies like SpaceX. It should also be less expensive for satellite users. Night launches are always beautiful, and this one was no exception. Oh yeah, I forgot to mention, this launch was at 2:30 AM! It was worth getting up early to see it though. A very strange phenomenon happened during the launch. Looking through the binoculars, as the two Falcon 9 boosters strapped to the side, separated, the glowing engines and vapor, created an image that looked very much like Voldemort’s dark mark in the sky!
SpaceX launched a Falcon 9 rocket carrying 60 Starlink satellites. Although the satellites were small, it was the heaviest load a Falcon 9 has lifted into space. The satellites are the first of up to 12,000 satellites that will make up a blanket of satellites that will provide a space based internet connection. Technological advancement or space pollution? Astronomers are already complaining, satellites are impeding viewing of the stars. Only time will tell.
The launch took place at 10:30pm. Night launches are awesome to watch. They make a really cool photographic subject. But also watching a launch at night is really beautiful. The flames from the rocket engines make all sorts of interesting shapes and colors. On a clear night with a pair of binoculars, you can follow the rocket all the way into space.
