 ===Trivia about posting time===
-The launch time was about 7 hours after this comic appeared. The release day of this comic was Christmas Eve the 24th of December. As can be seen from when [https://www.explainxkcd.com/wiki/index.php?title=2559:_December_25th_Launch&oldid=223041 this page] was created 05:02:00, 25 December 2021 (UTC), the comic came out at least 7 hours before {{w|Ariane flight VA256|launch}} which was 12:20:00, 25 December 2021 (UTC). Since Boston ([[Randall|Randall's]] home town) is 5 hours after UTC then the comic must have released close to midnight on the 24th for Randall, and clearly before midnight for the rest of the time zones in the US.

 Web comics are usually drawn some time in advance. When this comic was drawn and scheduled for publication, it is possible NASA had not yet [https://www.nasa.gov/feature/james-webb-space-telescope-launch-update announced] that the launch of JWST was slipping from Christmas Eve to Christmas Day.

 The {{w|James Webb Space Telescope}} (JWST) is a space telescope jointly developed by NASA, the European Space Agency, and the Canadian Space Agency. It has suffered many, many delays over its development period (as previously referenced in [[2014: JWST Delays]]), but it finally launched on Christmas day, December 25, 2021.
 In this comic, the James Webb Space Telescope is finally ready to take off. However, an unfortunate circumstance occurs: {{w|Santa Claus}} himself, presumably on his way to or from delivering presents to children, crosses into the path of the launch rocket. The joke is the implication that, right on the brink of success, this extraordinarily unlucky incident will either destroy the telescope, harm Santa, or cause yet another delay, much to [[Cueball]]'s horror.

 The JWST has been referenced previously in [[1730: Starshade]], [[2014: JWST Delays]], [[2447: Hammer Incident]] and [[2550: Webb]], is on the list of payloads in [[1461: Payloads]] and its planned use was indirectly referenced in [[975: Occulting Telescope]].  Santa is known to [[838|maintain a list of humans]] responsible for technological incidents and to have suitable punishment for offenders. 12 days after launch it was referenced again in [[2564: Sunshield]].
