Well, they finally announced.
 
Long Rumored, Finally Announced The rumors have been floating around for weeks about a supposed planet orbiting Proxima Centauri — the closest star to the Sun. That’s a star visible (through a telescope) from the Southern Hemisphere in the constellation…
Astronomers have finally found clear evidence for a planet around the nearest star, Proxima Centauri. It's an intriguing discovery!

My joke* may be nullfied.

I can see it being disassembled and reassembled along with various new Bigelow modules etc. In the future there will be a ceremony to decomission the very last piece of ISS.

*Q. Why is it so important that NASA complete ISS on schedule? A. So that it can be disassembled and burnt up in the atmosphere on schedule.
 
NASA announces it will sell the Space Station sometime around 2014 - after appropriations from Congress for its maintenance are set to run out.

Likely candidates are SpaceX and Boeing to buy it and continue their space operations with the first commercial platform in space.

An interesting coincidence is just this week ISS installed a new doc just for SpaceX given their more frequent trips back and forth with many more scheduled.

I have a hunch SpaceX won't actually want it, opting instead for a new station of their own design (likely partnering with Bigelow).

Boeing could use it, likely for Space Defense and weapons system research - though that uses is technically illegal at the moment per international space treaties, as I understand them.

One lucky company might just get their hands on one of the most coveted piece of property in the universe. NASA is reportedly handing over keys of the International Space Station (ISS) to a commercial owner by the mid-2020s.

There will be a Bigelow taj Mahal in orbit by then anyway.

Looks like the Falcon 9 first stage from Saturday night’s JCSAT-16 launch is pulling into Port Canaveral:

To quote or paraphrase someone: "Any day with a rocket landing is a good day".

SpaceX just needs to complete the deal, and it may still happen this year, by starting to reuse these stages.

I wonder if they will clean the soot off? What is the mass of all that soot?

Perfect launch and successful single engine first stage landing on the drone ship Of Course I Still Love You. Congratulations’ SpaceX!

See the little puffer bellies all in a row.
 
holy crap
I knew the Falcon 9 was 70 meters tall, but this photo really shows the scale
I like this pic of a SpaceX rocket with people next to it because it's hard to get a sense of scale in landing vids. Embedded image. 2:37 PM - 19 Aug 2016. 54 Retweets67 Likes. Reply to @hypercubexl. Replies. Marcus Conge. 3h3 hours ago. Marcus Conge @RockingThePixel. @hypercubexl Yeah it is!

The device they are attaching (right now!) will allow Dragon 2 and other compliant vechicles to dock all by themselves, rather than approaching ISS and having to be grabbed with an arm.
 
Tune in at 6:30 a.m. EDT to watch as two U.S. astronauts install a new “parking spot” on the International Space Station during a #spacewalk. This new docking port’s main purpose is to provide a port for spacecraft bringing astronauts to the station in the future. Watch: http://www.nasa.gov/nasatv

Among macrophotography enthusiasts are those who photograph algae.

Melosira is a genus of filamentous diatoms - shaggy brown threads that attach to rocks in streams and streal and sway in the current.
Posted: Mon Jan 28, 2008 1:06 pm Post subject: Melosira undulata, Reply with quote. Hello, recently a friend of mine gave to me a sample from his aquarium. Among some algae and critters there was Melosira undulata, a filamentous diatom, too. This is quite unusual, because M. undulata is known to ...

Heh. Yes, Google was working for me a couple days ago. I just wasn't working it. Cubesat reentry vehicles.

Google "nanosat reentry" if you don't want to click on this gobbledygook. It says Microsoft Word_, but it downloads as PDF. Maybe a "Save as..." retitling situation.

Again with the "thank you for instantiating my fantasies".

I'm still waiting for the reëntry vehicle, fuel depot, etc. No rush, though.
 
Could miniature #CubeSats one day serve as the building blocks of larger structures in orbit? The trick will be learning how to dock them together...
