"Oh, so you think space is pretty? Are you willing to remove your appendix and gallbladder for it? To just go temporarily blind because of your body fluids moving during weightlessness?"

It's easy to go down a rabbit-hole of negativity these days with everything going on in the world, but for the next sixteen days and change, there is at least one source of positivity and love that is here for us. Twitch is running an 18-day marathon of the children's classic TV show, Mister Rogers Neighborhood.

The next generation of astronauts is stepping up to the place with a bold goal—make it to Mars within their lifetime.

The still, 2D images of Mars' landscape captured by the HiRISE camera aboard the Mars Reconnaissance Orbiter are fascinating on their own, but since most of us are unlikely to ever visit the planet—though that could still change—we'll never really get to see what it truly looks like. So, Finnish filmmaker Jan Frodjman digitally mapped those images with 3D topography and created this incredible flyover of the Red Planet's features.

It's no secret that TMS loves Kamala Khan, so I couldn't stop smiling when I saw this awesome live-action Kamala fan film! Watch for the joy of the fan film and the rage of asking yourself, "Why hasn't Marvel given this character a movie yet?"

I gotta admit, I haven't been paying much attention to the Beauty & the Beast reboot starring Emma Watson, so I didn't realize it was a musical, and that Emma Watson herself would be singing the iconic Disney soundtrack.

Go ahead and take a look at this mashup between Luke Cage and Family Matters and marvel at just how well these two diametrically opposed titles blend together so well.

Getting to Mars is only part of the problem of putting humans on the Red Planet. We're already pretty good at that part, with plenty of robots roaming around up there right now. The tough part is putting a permanent presence in place so that it actually makes sense to go there, and Elon Musk's SpaceX is making progress towards overcoming that difficulty.

Leaving the Earth for Mars has a lot of downsides, especially in being confined to a small space with only your fellow travelers for a very long time, but it also has one big upside: You get to make a sci-fi dream a reality and actually set foot on another planet. Earth-bound testing, on the other hand, offers no such benefit, which makes a year-long practice Mars mission right here on Earth all the more impressive.

If there's one thing I know about small teams of astronauts engaged in interplanetary exploration, it's that at least one member of the team has to be a robot.

Aside from the fact that Mars is a harsh, inhospitable environment that we'd have to drastically terraform—or pretty much just never go outside—to live in, the logistical implications of actually getting people there in the first place provide a pretty sizable obstacle. Luckily, SpaceX is about ready to blow that obstacle away with an impressively powerful rocket, and they're about ready to start testing it on their path to real missions to Mars.

The Curiosity Rover has been on Mars for four (Earth) years today, which means it's time, yet again, for another lonely birthday celebrated on distance space rock with no one else around—except for the other rovers also left to live up there alone. In honor of those four years of incredible science on the Red Planet, let's listen to the birthday song the rover sings to itself to mark its lonely passage of time.

NASA's HiRISE camera snapped a really neat photo of some dunes on Mars that look like the dots and dashes that make up Morse code.

This poster created by Tumblr user EntertainMeWeakly for a fake Bryan Cranston-starring Stan Lee biopic is pretty convincing.

The Curiosity Rover is far away and generally alone (unless you count other rovers elsewhere on the planet), so when it encounters a problem and goes into its minimal operation mode, figuring out just what happened can be a tense process. That's just what NASA's scientists are currently trying to do, as the rover entered its "safe mode" over the weekend for unknown reasons.

Venus may be a lot more like Earth—in terms of size—than Mars is, but Mars may once have been similar to Earth in more meaningful ways, unlike now, when it pretty much shares the general quality of being a giant ball of death with all the other planets in our solar system. Evidence is mounting that Mars once had lots of oxygen in its atmosphere to go along with its oceans of water, but that doesn't necessarily mean it fostered life; it couldn't been part of that "death ball" transformation.

A group of 12 comfort dogs from Chicago were flown out to Florida to help provide comfort to survivors of the horrific events that took place in Orlando on Sunday.
