Despite what Jules Verne may have you believe, it’s not exactly possible to journey to the center of the Earth. As such, it’s pretty difficult to gain a full understanding of what the core of our planet looks like. NASA is trying the next best thing. 

It’s set to launch a mission to an asteroid that’s understood to be largely made up of iron and nickel. In fact, this metal-rich asteroid, which is called 16 Psyche, is believed to once have been part of a planetary core. This is the first NASA mission to study an asteroid that has more metal than rock or ice.

Launch for the Psyche mission is targeted for 10:16AM ET on Thursday. The spacecraft will launch on a SpaceX Falcon Heavy rocket from Kennedy Space Center in Florida (this will be the first of several NASA science missions in which the primary payload will launch on one of those rockets). You can watch a live stream of the launch below.

The Psyche spacecraft is around the size of a small van. As soon as it reaches the asteroid, it will start sending images of 16 Psyche back to Earth. It’s equipped with a magnetometer, a gamma-ray and neutron spectrometer and a multispectral imager to study the asteroid. It will spend around two years snapping photos, mapping the asteroid’s surface and collecting data to gain a better understanding of 16 Psyche’s composition.

The spacecraft, which is powered by solar electric propulsion, is expected to reach 16 Psyche (which is in the main asteroid belt between Mars and Jupiter) in July 2029. If NASA had been ready to launch the mission last year, as was previously the plan, it might have been able to reach 16 Psyche as early as 2026.

NASA understands that the 173-mile wide 16 Psyche asteroid may, in fact, not be an exposed core of a planetesimal, an early planetary building block. The agency says that it might instead be the “leftover piece of a completely different kind of iron-rich body that formed from metal-rich material somewhere in the solar system.”

The spacecraft will have a second job to do. It will also test new laser communications tech from NASA JPL called Deep Space Optical Communications. This is said to be able to transfer data and images at least 10 times faster than conventional systems. The experiment will test how capable the system is of transmitting data at faster rates beyond the Moon. However, it won’t be used to send back any Psyche mission data.

Just ahead of Google’s October “Big Deal Days” Prime Day sale, multiple Nest products are on sale, some back to all-time low prices. The easy-to-install Nest Doorbell (Battery) and Nest Cam Outdoor have particularly steep discounts of $60, letting you grab them for just $120 each (33 percent off). Meanwhile, the Nest Security Cam indoor is also on sale for $70 (30 percent off), one of the steepest discounts we’ve seen.

The Nest Doorbell (Battery) is a popular item because it’s much easier to install than any wired doorbells. As with the cameras, it will send you alerts when you have a visitor and you can chat with them through your phone and the built-in speaker and microphone. Google’s “intelligent alerts” can tell the difference between a visitor, a package being delivered, an animal sighting and more, so you can see if a situation requires your immediate attention. If the regular $180 price has made you pause, it’s now on sale for $120.

You can also pick up the Nest Cam Outdoor for just $120, or $60 off the regular $180 price. That model obviously has a weatherproof design so that you can install it outside your home, along with expanded Night Vision to better spot outdoor intruders. It also packs an internal battery that lets you set it up without the need for an AC plug, providing up to seven months of battery life before a recharge depending on usage.

Other deals are available as well. The Nest Cam indoor is designed to blend in to your home, with a range of colors, built-in stand, wall mount and hinge, and is currently on sale for $70 or 30 percent off the regular price. The sale also includes the Google Nest Doorbell (Wired) and other products — to see everything check here.
