Artemis Launch Attempt #3: Third Try Was The Charm

Finally, it launched! This trip was unlike the previous two, in lots of ways.

After the previous two scrubs, two hurricanes delayed the launch attempt from September all the way into the middle of November. My wife couldn’t go this time because she had a work conflict. So I made the trip alone, this time flying. Because the launch window opened at 1:04 AM, I didn’t even bother with a hotel. I took an airline flight to Orlando, got a rental car, drove to Titusville, and with several hours to kill, visited several parks looking for birds. I explored the Titusville and Cocoa areas. Finally, it was time to go.

For the previous two attempts, parking was at Space Coast Regional Airport. This time it was at a warehouse. I drove up, parked, waited because I was early, and finally boarded the bus for the ride to the Banana Creek viewing location. I didn’t bother taking any shots on the pad: it looked the same as it did for the previous attempts.

It was a long wait, several hours in fact. Then there was a series of problems that the launch team addressed, leading to a long countdown hold. I wondered if there would be yet another scrub.

Finally the countdown restarted. The NASA team dimmed the lights on the bleachers. The countdown got to a few seconds left, and I held my camera up.
Artemis 1 Liftoff
The bottom of the rocket lit up, the clouds of smoke and steam billowed, and the rocket lifted off. It got brighter and brighter as the flame got longer. The whole area was bathed in orange light. As it climbed, eventually the sound reached us in the crowd. It wasn’t deafening, but it was really loud and the bleachers started shaking. I watched the rocket for about seven minutes, until I lost sight of it, already more than a hundred miles down range. Even though I adjusted my exposure settings, my photos of the rocket after it cleared the tower were mostly just long flames with trailing smoke. The rocket itself is hardly visible in the photos. Eventually the solid rocket boosters separated, barely visible in the distance.

A long trail of smoke was left behind, hanging in the sky for a few minutes. Finally we boarded the buses, made the drive back to the warehouse, and I got back to Orlando at about 4AM. I tanked the car, turned it in, switched to an earlier flight, and came home.

Boy am I tired! Actually I’m exhausted. But I could only sleep for an hour when I got home. But I’m sure I’ll sleep well tonight! And it was an awesome experience.

Artemis 1 Launch Attempt #1

 

Artemis 1 on the Launch Pad

My wife’s former colleague, who works for NASA, invited my wife (and me as a guest) to watch the Artemis 1 launch from the Kennedy Space Center. My wife and I made the long drive from Virginia to Florida. We followed the instructions to check in and claim our credentials. We were surprised to find that the check in location was a shopping mall.

Titusville Mall

This mall, like so many, has lots of vacancies. Many of its stores were closed and the parking lot was almost empty. Its best days may be behind it. But that made it a good place for visitors to check in. There was plenty of parking, the mall was almost empty of shoppers, and we didn’t have to go through any security to get our credentials.

At check in, we were told to meet the busses at the Space Coast Regional Airport at 1AM the next day. That’s right: 1AM for a launch window that started at 8:33 AM. So that’s what we did. We arrived shortly before 1 AM and lined up with hundreds of other cars. We were directed to park on the grass near the runway. After we parked, we boarded a bus and rode to the Banana Creek viewing area. It’s adjacent to the Saturn V Center, which is a spot on the Kennedy Space Center public tour. I’ve actually been to this location twice before, so I knew what to expect. We arrived at about 2:30 AM. There we picked a spot in the bleachers and waited. I took a few photos of the rocket on the pad. 


Artemis 1

During and after tanking, there’s a hydrogen bleed process. The hydrogen gets sent to a vent where it is ignited and burned off. The flames were often visible from our spot in the bleachers. The floodlights on the rocket also lit the clouds up.

There is a public address system at this site along with a large TV screen. We received several announcements while we waited in which we were kept informed as to the progress of the tanking process.

As the sun came up, the clouds over the ocean formed a nice backdrop. The hydrogen flame continued to burn in the background as the liquid oxygen tank vented a white cloud from the upper stage.

The sun rose at about 7 AM and it began to get hot. I wandered the grounds and counted about 50 busses, and if each was full when it arrived, then there were probably close to 2,500 people waiting for the launch.

About 8 AM, the announcer described a problem with the #3 engine on the core stage, and at about 8:45, the mission was scrubbed. We went back to the busses, rode back to the airport, and left for the day.

The Banana Creek viewing area is a great spot. It overlooks a large body of water. Launch Complex 39 is clearly visible, especially from high in the bleachers where it’s possible to see over the bushes at the water’s edge. I used a 500mm lens. At that location, the towers and rocket filled the frame. This lens is big, heavy, and unwieldy, but worth it.

Our instruction sheet said that there would be a limited supply of food and water. This turned out to be false. There are restrooms at the Banana Creek site (with running water) and the visitor center opened at 4:30 AM (with a food vendor inside), and other vendors offered snacks and drinks for sale outside the visitor center.

So, there was no launch. Hopefully we’ll get another chance to see it go.

Cygnus NG-15 Launch

Every now and then NASA sends a resupply payload to the International Space Station. Some of the missions launch from the Midatlantic Regional Spaceport (MARS). My wife and I sometimes go watch the launch when the date/time is convenient.

We usually drive to Chincoteague and park on/near the causeway that leads to Assateague Island. There's a good view from there to the launch site.

While it's fun to watch this, photography is hard. The pad is several miles away, visible in the distance. Even on a cold day (like yesterday) there is a haze that makes sharp photos impossible.

The atmospheric distortion can even make the rocket itself look bent.
Distortion
As the rocket climbs, the air through which I'm shooting is cleaner and less disturbed, but by then the rocket is farther away so it appears smaller. This is also when the noise of the launch finally reaches the causeway. The roar is not loud, but lasts a while, even as the rocket disappears.

Eventually the rocket gets far overhead and fades away.

I was ready for the cloudy contrail this time. But, there was no nice pretty trail to shoot.

Rocket Launch

This past weekend my wife and I went to Chincoteague to watch a rocket launch.

The Mid-Atlantic Regional Spaceport, aka MARS, has a couple of launches per year, usually to the International Space Station. These are unmanned resupply missions. We've gone twice before to watch a launch. The first time was perfect: it was a night launch and we had beautiful weather. We arrived in town and were directed to the school parking lot. There, we caught a bus to the circle in town near the causeway that leads to Assateague Island. We, along with hundreds of other people, watched the launch that took place miles away. We had a great view over the coastal swamp and open water. The second trip was a bust. We stayed overnight, set up in frigid cold to watch, and the launch was scrubbed seconds before the target time.

This time the launch went on schedule. We got there a couple of hours early, parked on the causeway, and waited. It was chilly and sunny and clear. It was really cool to see the launch. The delay in hearing it was just as I remembered from the first launch that I witnessed. The pad is several miles away from the viewing area; it took time for the sound to reach us. The rocket was nearly out of sight before we heard the launch.

I'm disappointed with the pictures. It was hazy at ground level so sharp pictures were impossible. Even after it climbed I had a hard time getting sharp photos; it was just too far away. But I'll post them anyway.

Here's a shot just after liftoff, with the steam from the water that cools the pad creating a cloud on the left.
Just After Liftoff
 High in the sky, here you can see the two plumes from the two rocket motors. I darkened this one in post-processing to show the flames.

 The exhaust left a cloud that hung in the air for a little while.
Smoky Trail
Nearly out of sight, it looked like an airplane with a contrail.
Approaching Main Engine Cutoff
So I learned a few things. First, the advice I found on shooting this event said to underexpose a couple of stops because the rocket motors put out a lot of light. That turned out to be the correct advice. I also read that manual mode, f8, ISO 200, 1/1000 are good exposure settings. That also turned out right. I set up on a tripod with a gimbal head. Worked great. What will I do differently, if I ever do this again?
  • Focus on infinity, tape the focus ring, forget about trying to focus. It's all happening at infinity. Forget the focus button, which I kept pushing out of habit.
  • Have a second camera with a 70-200 lens ready to shoot the smoky trail. My 500mm lens was too much for that and I could only get part of it at a time.
