#IfYouReadOneThingToday - On Perseverance

One way or another, history will be made tomorrow.

As I write this, NASA's Perseverance lander is speeding toward Mars, and tomorrow it will hit the atmosphere and attempt to pull off a complex, highly choreographed, completely autonomous landing that will hopefully end with it sitting upright and intact in the middle of Jezero Crater.

It'll take 7 minutes from the moment Perseverance hits the upper reaches of the thin Mars atmosphere to the time it touches ground, and that time is often referred to as the 7 Minutes of Terror. The Curiosity rover followed a similar trajectory when it landed over 8 years ago, and now it's Perseverance's turn.

If you can, watch. Because science can do wonderful things - the obvious ones like explore new worlds and push the boundaries of engineering, and the less obvious ones like connecting us all to a common good back here on Earth. Either way, it promises to be quite the show.

In the meantime, the good folks at the Jet Propulsion Laboratory have put together another 7 Minutes of Terror video outlining the entry, descent, and landing (EDL) phase of the mission, and why we won't want to look away.
