"Spaceflight Is Hard"

The video discusses the explosion of a SpaceX Falcon 9 rocket carrying supplies to the ISS, highlighting the uncertainty surrounding the cause. It then shifts to the New Horizons mission to Pluto, detailing the challenges of hitting a precise target for observations. The video also covers the Rosetta mission's findings on Comet 67P, including icy spots and sinkholes. Finally, it encourages viewers to support the show through Patreon.

What was the initial theory about the cause of the SpaceX Falcon 9 explosion?

• Excessive pressure in the second stage liquid oxygen tank

• A malfunction in the first stage engines

• A software glitch in the navigation system

• A collision with space debris

Why is the New Horizons mission to Pluto considered challenging?

• A bright icy cap

• A strange dark cap

• Volcanic activity

• A large crater

What did the Rosetta mission discover about Comet 67P?

• It is composed entirely of rock

• It has icy spots and sinkholes

• It contains large amounts of methane
