Why Atlas Is Using Dual Engine Centaur For Starliner
Boeing's Starliner crew vehicle will be the first payload to use the Dual Engine Second Stage on the Atlas V since 2004. While the 2 engine version offers better payload to orbit, it's very expensive and the actual reason for the 2 engine requirement is a bit more subtle and stems from earlier plans for post-Shuttle crew vehicles.

CHILD
children-of-a-dead-earth-space-wars-with
Every game with space combat is pretty much completely unrealistic with vehicle designs and mechanics being governed by the rule of cool. Children of a Dead Earth attempts to adhere to realism as much as possible and presents an interesting option for sci-if fans.
The game is available on Steam for Windows and Mac

spacex-launch-the-dart-spacecraft-to
Long time no post? I took a trip to see the DART launch in person, and it was an amazing experience, I'd love to share all my amazing photos, but most of my photos were terrible, so all the good ones are in the thumbnail.
But seriously, in the last week there's been a lot going on and I'm thinking of making the deep space update format a regular thing to cover the space news events without going into every detail. So here's a bunch of other space news tagged on to hide the fact that my photography only covered a few minutes.
Brian Sandoval captured the long exposure image showing the second stage turn, his website is selling this image and others:

nasa-spacecraft-returns-extraterrestial
NASA's OSIRIS REx spacecraft completed its primary mission by returning a large sample from the asteroid Bennu to Earth over the weekend, dropping its sample return capsule neatly onto a test range in Utah after giving the engineers some concern that it might crash.
Now the material has been recovered it'll be sent to labs to be analyzed using technologies and instrumentation which could never fly on a spacecraft.
Meanwhile the parent spacecraft is renamed OSIRIS APEX and is headed toward a rendezvous with Apophis.

the-lead-scientist-behind-nasa's
Dante Lauretta has been working on the OSIRIS REx mission for the better part of 2 decades, all the way from the early proposal, through the design of mission, target selection and the experimentation with the sample acquisition process. Even after launch there are new problems they've had to solve to support the plan of returning a substantial sample of a primitive asteroid and return it to Earth.
Most of the asteroid images in this video are from the mission website: https://www.asteroidmission.org/
And, on top of that he has a hobby of designing board games too, he's currently running a crowdfunding campaign to support the development of an updated version of Xtronaut

If you are interested in the other games and don't want to get involved in Crowdfunding you can buy them from Amazon
