This is another comic in the [[:Category:My Hobby|My Hobby series]]. This one is depicted with three drawings illustrating the core concept and explained in detail in the caption. The launch company {{w|SpaceX}} has developed a reusable rocket system, where the {{w|multi-stage rocket|first rocket stage}} is capable of landing back on either the launch pad or an {{w|autonomous spaceport drone ship}} after launch (See [https://www.youtube.com/watch?v=lEr9cPpuAx8 this video] displaying both types of landing, from when the sea landing was successful the first time). The landing pads and ships are decorated with a "X" symbol from the SpaceX logo, with the center of the X being the desired landing spot.{{Citation needed}}

This is another one of the "[[My Hobby]]" series, where [[Randall]] tells about a strange hobby. This is probably the most destructive one so far, as it would result in the loss of nine space rocket engines.
  
Randall imagines creating a similar-looking barge and placing it near the intended landing site, except his barge's platform would be hollow in the middle with only a sheet of paper supporting the part where the rocket would land. Since the paper is painted to look just like the real landing platform, the goal of this setup is presumably to trick a returning first stage rocket into falling into the sea. This is the same concept as the old {{w|trapping pit}}. If a rocket attempts to land on Randall's barge, it will quickly burn through the paper and fall through the hole.

The launch company {{w|SpaceX}} is currently testing a reusable rocket system, where the {{w|multi-stage rocket|first rocket stage}} is capable of landing back on an {{w|autonomous spaceport drone ship}} after launch. The rockets guide themselves in to land by aiming towards a giant launch pad with the "X" from the SpaceX logo painted on it. Randall imagines creating a similar-looking barge and placing it near the intended landing site, except his barge's platform would be hollow in the middle with only a sheet of paper supporting the part where the rocket would land. Presumably the goal of this setup would be to trick a rocket into falling into the sea, similar to the old {{w|trapping pit}}. If a rocket attempts to land on Randall's barge, it will quickly burn through the paper (assuming the paper had not already been destroyed from being soaked by ocean spray) and, not having enough time or fuel to readjust its course, fall into the sea.
  
There are several reasons why this setup would not work in real life. First, the rocket actually navigates to the landing site using GPS coordinates shared with the real barge.  It does not use cameras to identify its landing site and will not recognize another barge based solely on a painted logo.  Also, a wide area around the rocket's flight path would be restricted around the launch window due to safety concerns. Vessels that are not part of the official launch plan would not be allowed in the area. Even if the fake barge manages to enter the area and does not get removed by authorities, at most it will cause the launch to be cancelled for the day. From a practical perspective, Randall would need to sabotage the actual barge without anyone at SpaceX noticing.

This hobby seems more appropriate for [[Black Hat]], considering that he is a real [[classhole]].
  
This "my hobby" is probably the most destructive one so far, as it would result in the total loss of the first stage containing nine space rocket engines. The costs associated with buying and remodeling a barge would also likely make this the most expensive hobby, even disregarding the costs to others, though it could potentially be reused if it did not get destroyed by the falling rocket. This hobby seems more appropriate for [[Black Hat]], considering that he is a real [[classhole]], and goes to show that Black Hat is as much part of Randall's personality as [[Cueball]].

The title text plays on the incredible difficulty of successfully landing a rocket on a barge.  Such a feat has only recently become possible, some 60 years after the launch of {{w|Sputnik_1|Sputnik 1}}. Randall imagines an even more implausible idea of launching an entire ''barge'' into the air and have it land on the ''rocket''. Launching a barge in the first place would be tremendously difficult - they are big, heavy and not very aerodynamic [[https://en.wikipedia.org/wiki/Aerodynamics]].  Having one come down on top of a rocket would likely destroy the rocket as well - but it would be worth it for the spectacular explosion.
  
The title text plays on the incredible difficulty of landing a rocket on a barge. Reusing rockets like this is a feat that has only recently become possible, some 60 years after the launch of the first satellite {{w|Sputnik 1}}. SpaceX, founded by [[Elon Musk]], was the first (and so far, only) organization to do so successfully. {{w|Blue Origin}} is also currently testing reusable rockets and achieved [https://www.youtube.com/watch?v=nNRs2gMyLLk landing their first stage] before SpaceX, albeit [https://www.youtube.com/watch?v=b8c7RUjNFDo only on land and only with a sub-orbital rocket].

This comic was published on the week following SpaceX's Iridium 1 mission, where the first stage of the rocket which delivered 10 satellites into orbit successfully landed on a barge near California. It marked the seventh time SpaceX successfully landed and recovered its booster on a commercial mission.
 
 
Thus Randall imagines an even more implausible idea of turning the scenario upside down and getting a barge to land on one of Elon Musk's rockets. That would be a spectacular feat of engineering, and the challenges it presents as well as its inherent irony appear to satisfy Randall so much that he would make it into one of his life goals. Launching a barge in the first place would be tremendously difficult - they are big, heavy, and not very {{w|aerodynamic}}. Maneuvering it through the air precisely enough to come down on top of a rocket would be difficult as well. The barge (and probably the rocket) would have to be redesigned if the goal is a soft landing, otherwise the falling barge would certainly destroy the rocket and possibly itself.
