The episode also featured some parent drama, and helped introduce Logan's parents, Aaron Harry Hamlin and Lynn Echolls Lisa Rinna , to the world of the show. While Season 1 followed Lilly Kane's murder, Season 2 needed a new season-long arc, and found it in the mysterious bus crash that killed some Neptune High students and left Meg in a coma. In fact, a team of InSight seismologists in Zurich had to amplify those seismic signals by a factor of 10 million in order to accurately simulate the shaking on the scale of an earthquake. On Earth, the source of seismic waves is easily detectable, since the crust is comprised of relatively uniform, solid rock which has been melted and re-paved by volcanic activity over millions of years. As the core cools, the material contracts, which causes stress to build.

But, lucky for us, all three seasons of Veronica Mars are now available to stream on Hulu, and these are before the show returns for Season 4. Not all quakes are created equal. The lander's built-in seismometer detected its first quake in April. Reading the seismic waves on Mars, scientists hope, will reveal clues about what the planet's inside looks like and how it's changing. This finale offers one of the most heartbreaking resolutions in the series, and ends on a cliffhanger guaranteed to make your jaw drop. Beyond that, though, this episode is great for the tension between Keith and Veronica as they stand on opposing sides of an issue — whether or not Mr. And now, thanks to Hulu, there's nothing stopping you from revisiting this series and remembering what made it so great.

And that's why we've picked out the best and most essential Veronica Mars episodes to prepare you for what's coming.

Fans had always had mixed feelings about the character, and even actor , according to Yahoo. However, seeing him and Veronica have one last hurrah sneaking him out of the country — as well as publicly faking their breakup — is kind of sweet. After Duncan and Veronica found tapes of Lilly and Aaron together and realize he was the one who murdered her, the tension reaches an all-time high. Much more to learn Twenty-plus Mars quakes aren't enough to reveal the red planet's secrets. After a season of them being apart and dating different people, seeing him tear up and attempting to get her back likely gave many hope that the two would reconcile. In the future, Panning would like to see sensors installed on every planetary body that quakes, especially , a moon of Saturn from which plumes of water shoot out.

And then things only got more complicated from there. Still, it's been a while since fans saw Kristen Bell in action as the titular detective. Mars doesn't have tectonic plates, though. Veronica Mars premiered in 2004 only to be cancelled three seasons later. On Earth, for example, tracking how seismic waves move through the planet's interior helped researchers calculate the size of its core. When the Earth shakes, it's because tectonic plates in the crust are clashing at fault lines. The red ones follow as a result, and seismologists can use the lag between them to calculate how far away the quake's source is.

The long waves of red and white that spread along the sides of the animation are surface waves that bounce through crust material — their reverberations suggested the moon-like qualities of Mars' crust. Not to mention, it added a whole new drama to the investigation into Lilly's death, when the man convicted of her murder, Abel Koontz, revealed that Veronica and her ex, Duncan, might be related, which, ew. A person standing on Mars would not have been able to feel any of the shaking InSight's tools picked up. Perhaps a high school having a secret society is a bit far-fetched. So scientists think Mars quakes probably come from a constant internal cooling process, which happens inside most rocky planets. It also dealt with one of the more awful aspects of high school: slut shaming. It's been basically sitting there for billions of years and getting hit by meteorites.

For these reasons, the InSight team is still waiting for a big quake that travels through the planet's core. That's why earthquakes last for just a few seconds or minutes. Until now, we could only look at it from the outside. This episode was fraught with romantic tension, and though the show hadn't yet reached the boiling point between Logan and Veronica, seeing the two of them start to move past their antagonistic relationship is what started the LoVe ship — even if it only happened because Logan was devastated over his mother's death. Apollo astronauts installed seismometers on the moon.

So far, the length of Mars quakes seems to fall somewhere in the middle of the moon's and Earth's, at about 10 to 20 minutes. The , made by an InSight at , shows the different types of waves the InSight team is studying. Fans of Gossip Girl and Parks and Recreation will love this episode for the Leighton Meester and Adam Scott appearances. It's a welcome change, since they have one of the best dynamics on the show, and Wallace can sometimes be a little under-appreciated. Mars once had plenty of volcanic activity and water. Meanwhile, Logan's family is falling apart with the possible death of his mother, hinting at future complications for him and his father. Sadly, Meester didn't reprise her role in the Veronica Mars movie, and the character didn't exactly get a happy ending.
