The computing power of the Mercury spacecraft compared to a modern iPhone is starkly different, highlighting the vast technological advancements over the past decades.

Mercury Spacecraft (1959-1963):

- The Mercury spacecraft's computing capabilities were minimal. The onboard systems were primarily mechanical and analogue, with minimal digital computation. Most calculations were done on the ground, and communication with the spacecraft was handled through radio telemetry.

- The only real "computer" involved was the ground-based IBM 701 or 7090, which handled data processing and flight simulation.

- The onboard systems mainly relied on simple transistor-based electronics for control and navigation, with computation power measured in just a few thousand instructions per second (KIPS).

Modern iPhone (e.g., iPhone 14 Pro):

- A modern iPhone has a multi-core processor with billions of transistors and can perform up to trillions of operations per second (teraflops). For instance, the A16 Bionic chip can handle up to 15.8 trillion operations per second.

- The iPhone also includes advanced graphics processing units (GPUs), neural engines for AI and machine learning tasks, and substantial amounts of RAM and storage.

Comparison:

The Mercury spacecraft's computing power is dwarfed by that of a modern iPhone, which is millions of times more powerful in terms of computational capability.

- To put it in perspective, the iPhone in your pocket has more computing power than all of NASA's computers combined at the time of the Apollo moon landings, let alone the Mercury missions.

- The iPhone can perform complex computations, support high-resolution graphics, and manage extensive communication and data processing tasks that would have been unimaginable with the technology available during the Mercury program.

In essence, the Mercury spacecraft had the equivalent of almost no digital computing power compared to the highly advanced and capable iPhone of today.
