The cosmos seem silent and empty of any great interstellar empires, but perhaps they once existed, and if so, what titanic ruins might they have left behind?

The SpaceX Super Heavy Starship is already the largest and most powerful rocket ever built. Elon tweeted that future versions will be 10% to 20% longer. If the 20% longer development happens then the stacked rocket will be 144 meters long. Adding 24 meters would be over 60% of the length of the Space Shuttle orbiter which was 37 meters long.

Likely to be 10% to 20% longer in later versions.

The Seattle-based company aims to build a “100% reusable” spacecraft capable of an ambitious 24-hour mission turnaround time.

Seattle-based startup Stoke Space successfully landed its reusable second-stage rocket this week following a brief hop test reminiscent of SpaceX’s early Starship tests.

The recent test, called Hopper 2, allowed Stoke Space to successfully test several novel engineering concepts, some of which were considered by Elon Musk’s SpaceX but ultimately discarded.

Now, a YouTuber called Jay Bowles who goes by the name Plasma Channel built one and posted the process on his channel on Saturday. He started his video off by saying he was partially inspired to build the thruster by MIT’s model developed in 2018.

This version of the technology actually made a vehicle fly. “Their design was brilliant,” said Bowles in his video. “And it included aspects of a decades-old device called an ionic lifter.”

“He has these enraging qualities, these drives and these demons, but if you pull those out, you don’t have the impulsive character that sets things off,” said Isaacson, who shadowed Musk for two years while researching his book, which published on Tuesday.

“Musk would say you are actually being selfish if you’re sitting there hoping the people in front of you like you,” said Isaacson. “As opposed to cutting off that sense of emotional connection and saying, ‘What’s best for the larger mission?’”


Elon Musk’s reckless streak can’t be separated out from his track record of innovation at companies like Tesla and SpaceX, says biographer Walter Isaacson.

SpaceX’s Starship can seemingly get Federal Aviation Administration (FAA) clearance for its second flight test as early as next month.

What Happened: “We’re working well with them and have been in good discussions. Teams are working together and I think we’re optimistic sometime next month,” Acting FAA Administrator Polly Trottenberg said on Wednesday, as reported by Reuters.

Earlier this week, CEO Elon Musk confirmed that SpaceX has implemented all the fixes demanded by the FAA for Starship ahead of its second flight test.
