In six months, a large asteroid is going to hit Earth. It's likely that everyone is going to die. Only a few people know about it, and they are desperately trying to stop it from slamming into the planet. That's the premise of Salvation, a new suspense thriller TV series premiering on CBS this Wednesday, July 12, 2017. Carla and I got an early look at the first episode, and we both loved it for the premise, sense of urgency, moral issues explored, and hints that more is unfolding than meets the eye. Our friends Elizabeth Kruger and Craig Shapiro created the show, so I grabbed them for a quick interview to ask them about what went into making a series that deals with people secretly trying to save humankind.
Mark: What's the conflict in Salvation?
Liz: An asteroid is going to collide with Earth in 186 days, and if our government and/or others don't come up with new technology to solve the problem, we're going to go the way of the dinosaurs. Adding to that conflict is other countries that are also looking into how to solve the problem, and what do you do if the world itself cannot agree on how to solve a problem? And if you solve it on one side of the world what problems does it create for the other side of the world?
Mark: So if the different countries' solutions don't necessarily work in harmony with each other, they could actually conflict with each other. Read the rest

NASA reports that its first ever asteroid sampling mission launched into space at 7:05 p.m. EDT Thursday from Cape Canaveral Air Force Station in Florida, “beginning a journey that could revolutionize our understanding of the early solar system.”
OSIRIS-REx, which is short for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer, is headed to the near-Earth asteroid called Bennu.
The probe's job: Touch the asteroid (after asking consent first, and with a platonic vibe) so we can bring a small sample back to Earth for study. If all goes as planned after today's launch, the spacecraft will reach Bennu in 2018 and return a sample to Earth in 2023.

NASA announced today that a small asteroid has been discovered in an orbit around our Sun that keeps it as a constant companion of Earth. And it'll stay that way for centuries to come.

Scott Manley entered data for all the known asteroids near the Earth and made a cool 360 video of them.
I took all the asteroids near the Earth, calculate their positions and place them on a virtual Sky sphere. You can pan the view around, use a smartphone or tablet as a virtual window, or a Cardboard compatible viewer to see this the way it's intended.

The Geminids are one of the big deal meteor showers that happen every year. In fact, they're regarded as one of the most reliable and impressive. They're also a little strange.
Most meteor showers happen when Earth and a comet cross paths, slingling rocks, dust, and debris from the comet's tail into our atmosphere. The sudden influx of shooting starts that results is a highly noticeable event and humans have been recording them for millennia.
The Geminids are different. They sort of just appeared, seemingly out of nowhere, back in 1862. And it wasn't until the 1980s that scientists were finally able to identify the thing that was producing them. At which point, ish got weirder.
That's because the object, known as 3200 Phaethon, is really confusing. It doesn't seem to be a comet. At least, not a normal, healthy, functioning comet. It doesn't even have a tail. In fact, at this point most scientists think it's probably an asteroid, which then leads to still-yet-unexplained question of where all the meteors come from. Asteroids, after all, do not typically accumulate tails of small rocks. So far, the best guess has to do with 3200 Phaethon's orbit, which over the course of about a year and a half takes it closer to the Sun than Mercury and then back out further from the Sun than Mars. Those wild temperature swings might lead to the asteroid cracking and throwing off dust and debris, which then becomes meteors. But, as a NASA info page pointed out in 2010, that explanation doesn't totally cut it. Read the rest

In 2016, NASA will launch OSIRIS-REx
, an unmanned mission to an astroid called 1999 RQ36. It is, to say the least, not the most inspiringly named object in space. That's why MIT, the University of Arizona, and the Planetary Society are sponsoring a contest to rename it. If you are under age 18—and are capable of the official asteroid naming guidelines—then you can enter the contest

This is Vesta, the second largest asteroid in our solar system's main asteroid belt. Specifically, this is a view of Vesta's south pole, taken by NASA's Dawn spacecraft last September.
As it turns out, Vesta is a great illustration of the power of chance in the universe. Data collected by Dawn is showing that, once upon a time, this asteroid was on its way to planethood. But, for several reasons, it simply never grew large enough. From Science News:
... according to Dawn observations, Vesta did indeed agglomerate enough rocky debris as it grew to heat itself by the decay of the rock's radioactive elements. That heat led to the separation of the primordial body into a rocky crust, an underlying rocky mantle, and a central metallic core, hallmarks of planet Earth and the other rocky planets. Dawn was the first to detect Vesta's now-solid core.
Vesta isn't unique in this, but it does provide an interesting moment to stop and think a little bit about randomness and the process of planetary birth. This news about Vesta is a nice reminder that there's really no reason why our solar system has to have eight planets. It could have had fewer. It could have had more. And some bodies—like Ceres and Pluto—are really only a trick of taxonomy away from being planets.
