You might notice that the pictures are black-and-white, small, and noisy. There are good reasons for all of those things -- actually one good reason: As Cassini passed within 2000 kilometers of Saturn's cloud tops, it was traveling at a speed relative to Saturn of 34 kilometers per second. That is very, very fast, almost too fast for the camera to take images without motion blur. To avoid blur, you have to take very short exposures, which means the images look noisy. You have to maximize the number of photons reaching your camera, which means not placing any color filters in front of the camera, so the pictures are grayscale. Even with that, there would be some blur and limitations to how fast the spacecraft can get so many images off of its detector, so they downsampled the images to half the camera's native resolution in order to get a somewhat continuous strip of photos of Saturn's atmosphere throughout the plunge.

A Whole New Jupiter: First Science Results from NASA’s Juno Mission

Juno Media Teleconference

Quote

As NASA's Juno spacecraft flew through the narrow gap between Jupiter's radiation belts and the planet during its first science flyby, Perijove 1, on August 27, 2016, the Stellar Reference Unit (SRU-1) star camera collected the first image of Jupiter's ring taken from the inside looking out. The bright bands in the center of the image are the main ring of Jupiter's ring system.

Elon reminding us that Rockets are hard, and not to expect too much from the first Falcon Heavy launch, but come down and watch 'cause if we fuck up, the explosion might be really cool to watch.

Mike Brown and crew are up on Maunakea again looking for Planet Nine.

 

At the very least his search will probably bag some TNOs (which wouldn't entirely be a loss, since much of the evidence for Planet Nine is the non-random distribution of TNO orbital parameters).

 

Obviously hoping for success.

 

edit: sometimes I remember Nemesis doesn't exist, and then I get sad

Go big or go home:

To pay for the BFR, spaceX will totally refocus on BFR - falcon will stop production. Relying on a stockpile of legacy rockets (dragon and falcon) isn't as bad for spaceX as it is for other operators, because they can reuse the rockets, but it's still a bold move. Especially since they're expecting the totally reusable BFR to take over the small satellite market and still be cost competitive (might work if they have several satellites that want to be in similar orbits?).

 

Rocket travel between cities is cool, but unlikely. Rockets have avoided green taxes because no-one used them for travel - using rockets for transport will make it a target for hippies.
