This. There’s 5 Legrange Points for every 2 body system. They’re specific points around the 2 bodys where the gravity “cancels out”. In this case the 2 body system is the Earth and the Sun. JWST is sitting a million miles from Earth at L2.
SpaceX created the first successful Full Flow Stage Combustion Cycle Engine, so they’re also innovative in the propulsion department.
SpaceX has only had 2 mission failures out of 274 total missions. Since 2017 SpaceX has had a 100% success rate which is a vast majority of its total missions. The recent explosions have been test rockets and expected to blow up, it’s how they learn and innovate so quickly. NASA takes billions of dollars and 10+ years to successfully launch a rocket on the first attempt. It’s just 2 different approaches to design and innovation.
If you understand gravity wells, think of L1/L2/L3 as the shape of a saddle. If you’re right in the middle of the saddle it’s a pretty stable orbit, but if you get too close to any of the edges you fall right out of it. L4 and L5 are like the peaks of a mountain.
Also worth pointing out that only L4 and L5 are stable, L1/L2/L3 are only metastable where they require a bit of maintenance to stay there.
Another fun fact about Legrange Points: There’s a group of asteroids called the Trojan Asteroids. There’s technically two groups of these since they’re stuck in L4 and L5 in the Sun/Jupiter system.
