Recent events have brought back memories of past complications in my life. Particularly waiting for the birth of our son back in the 1970s. The pregnancy went quite well, but my wife had a series of false labor events. When the labor pains would start we’d begin to get excited anticipating the imminent birth of our second child. Back then we didn’t know if we were going to have a boy or a girl. The false labor pains repeated themselves four more times before the fifth time which was finally the real thing – the birth of our son.
The current situation I am talking about is certainly not comparable the false labor events, but is still similarly frustrating for those directly involved and interested bystanders. The situation is the postponement of the launch of the SpaceX Falcon Rocket which will send the Dragon Capsule containing two American astronauts up to the International Space Station (ISS). This will be the first time an American space mission is performed with the cooperation of NASA and a private company. It’s also the first time since July 8, 2011, the last space shuttle mission launch, that a space mission is launched from American soil.
Elon Musk has been working on this project since he founded SpaceX in 2002. Here is a short recap of the more recent events leading up to the manned launch.
In February of 2019 they launched the test flight for the Falcon Heavy. SpaceX launched their Falcon Heavy rocket Thursday April 11, 2019 on its first commercial mission. According to an article on CNBC.com published on Thursday 4/11/19 and written by Michael Sheetz and titled “SpaceX Launches Falcon Heavy and lands all three rocket boosters for the first time.” The vehicle was built by using three Falcon 9 rockets making a powerful a 27-engine vehicle.
This particular flight was called Arabat 6A because of the satellite they were carrying up to orbit in space. The article quoted Lisa Callahan, Lockheed Vice President who described the satellite as one of “the most advanced communications satellites we’ve ever built. The future looks bright for SpaceX as they have 5 missions already contracted including one Government contract worth $130 million to launch the Air Force Space Command-52 satellite and three commercial missions.
SpaceX has already been sending cargo up to the International Space Station (ISS) with it’s unmanned vehicle and now is embarking on the next stage of it’s program to actually fly humans to the ISS. The safety of astronauts onboard during the flight is something they have been contemplating for some time. This is where the LES comes back into view. It is the final step in taking humans back into space on this new rocket.
It is designated as either a Launch Escape System (LES) or Launch Abort System (LAS). Here is how it works. In case of an emergency abort caused by an automatic rocket failure detection or impending explosion the system would be activated. There is also a manual activation for the crew commander’s use.
SpaceX launched their Falcon Heavy rocket Thursday April 11, 2019 on its first commercial mission.

Now the greatly anticipated launch day arrived. Wednesday May 27, 2020 at 4:22 PM EDT was the scheduled launch time. It was raining at the launch site at Cape Canaveral, Florida and overcast with a thick cloud cover. The countdown continued as the hope was that the weather would improve enough for a “go.” Another issue was the overcast conditions downrange. That would be where the Dragon Crew Capsule containing the two astronauts would land if there were a major problem and the had to eject from the Falcon Heavy rocket. It would be difficult, if not impossible, to see where the capsule would land so they could be retrieved as quickly and safely as possible.
The countdown continued and a “go” was issued to begin fueling the Falcon Heavy Rocket with the liquid oxygen fuel. That had everyone hopeful that the launch would finally happen. They waited as long as they could and when the next weather update was given there was a severe thunderstorm warning for the area and that was the last straw. There is no way they would launch in a thunderstorm with the threat of a lightning strike and the compounded threat of possible tornadoes. The official word came down to scrub the launch stopping the countdown clock at 16:54 minutes to launch.
The launch was rescheduled for Saturday May 30, 2020 at 3:30 PM EDT which is 12:33 PM PDT. The two astronauts, Robert Behnken and Doug Hurley were definitely eager to board their spacecraft and finally liftoff on their way to the ISS. A side note, the two men were classmates together in the 2000 NASA astronaut training program. They met their future wives in that class and both of their wives have also worked in space.
Here we go again. Saturday May 5, 2020 and we’re waiting to see if the launch actually happens this time. Just a half hour before launch time the word is “go” concerning the weather which was one of the biggest issues that scrubbed the Wednesday launch. This time everything went perfectly! The launch occurred on schedule at 12:22 PM PDT (3:22 PM EDT). The two astronauts were on their way to a link-up with the International Space Station in 19 hours. A job well done.
