It is a significant difference. When it comes to orbit, there is no close enough, either you’re going fast enough or you’re not. They have not shown this thing can do what they say it can.
IFT-3 was completely empty and the tanks were full. Where is the weight of the crew decks, the solar panels and batteries, life support equipment, docking mechanism, food, water, and cargo? These are not trivial things, and they weigh a lot. Proving an empty shell can achieve a suborbital flight and be just barely not be in orbit is not proof of anything useful.
If they had shown there was a significant amount of delta-v left with this empty test article, then that’s one thing. But those tanks had a whisper of fuel left in them. I don’t believe for a second that it would have gotten that close when it was full of over a hundred tons of additional equipment.
I can’t say I know enough about the subject to agree or disagree in general, it seems pretty clear to me that these people are sore about the fact that the billion (trillion?) dollar corporation they pathetically stan for didn’t make it to orbit.
Like I think it really gets to them.
DeltaV is the amount you can change your velocity in space.
To put it another way, if a semi truck company says it’s new truck can haul 20 tons of cargo 500 miles on one tank/charge, and then during the press release with an empty trailer, it has to pull to side of the road at 400 miles driven because it’s out of gas, do you think it can get to 500 miles when it has 20 tons in the back? And the previous 2 press releases had the vehicle spontaneously detonate just after leaving the driveway.
That’s what starship did, it ran out of gas at almost the finish line while completely empty. There’s no way it can get itself + 100 tons to orbit if it can’t even get itself to orbit.
The point is a more accurate analogy would be the truck pulling over after 494 miles, with plenty of charge left in the batteries, because they decided not to continue the test during rush hour.
Sure, technically they didn’t make 500 miles, but they were pretty damn close, encountered nothing preventing it, and chose not to for other reasons. Continuing those few extra miles serves no purpose at this time,and is arguably contrary to successful testing
