Nice hangout about a collaboration between amateur astronomers & a professional team using the +Hubble Space Telescope 
 
Amateur astronomers have played a big role in astronomical research and the Hubble Space Telescope is not alone in enjoying the fruits of their labors.

When astronomers asked the question, Can white dwarfs in binary systems grow in mass? Amateurs were on hand to help guide Hubble to the best observations.

Understanding whether white dwarfs can gain mass is important, especially since they are the sources of a very important cosmic yardstick: Type 1a supernovae.  These supernovae were directly responsible for showing us that the universe is expanding and accelerating - which meant that it also gave rise to the idea of dark energy.

But making these observations of white dwarfs in order to see if they were gaining mass was tricky and older, rejected theories that cataclysmic variables might be the progenitors of Type 1a supernovae were being revisited.

Please join +Tony Darnell, +Carol Christian and +Scott Lewis as they discuss this very interesting Pro/Amateur collaboration using the Hubble Space Telescope to better understand Type 1a supernovae, white dwarf stars and cataclysmic variables.

Please bring your questions and comments and we'll address them during the hangout as well!
This Hangout On Air is hosted by Hubble Space Telescope. The live video broadcast will begin soon.

I'm not sure about the claim 'America's first space taxi'.  SpaceX already unveiled their Dragon v2.  SNC is working on Dream Chaser.  We'll have to see who is really the first to be a 'space taxi'.

But there is a dark cloud hanging over the future of the CST-100 - as well as Dream Chaser - and that is the future of the Atlas V.  Both the CST-100 and Dream Chaser have baselined the Atlas V as their booster.  But with the tensions between the US and Russia over Crimea, Russia is cutting off supply of the RD-180 engine used on the Atlas V.  There are currently 16 RD-180s in stock in the US, which is enough for roughly the next two years of operation.  All of those missions are already on the schedule.

There are political and industry efforts in motion to develop a US engine to replace the RD-180, because of this embargo, but we're looking at at least four years of development based on industry estimates.  And even once the engine is developed, it will still need to be 'man rated', which is harder with a new, unproven engine.

It is also possible that the political climate will change, and Russia will unrestrict the supply of engines again.  But that still leaves them with de facto control, and the ability to 'turn off' the supply again at any time.

The future of the Atlas V has direct bearing on the viability of the CST-100 & Dream Chaser.  If there is a break in availability of the Atlas V, it could set back both programs.  They could be forced to look at an alternative booster, such as the Delta IV, and pursue man-rating.  Though the Delta IV is more expensive to purchase and launch than an Atlas V, so that'd be a factor.  (Cryogenics are pretty much always more expensive than hydrocarbon boosters - the Atlas V is LOX/RP1 (as is the Falcon 9), the Delta IV is LOX/H2.)

SpaceX is unaffected, as they produce their own engines, booster, and capsule.

NEW VIDEO RELEASED THIS WEEK.  See the natural wonders of our planet from a unique perspective 370km (230 miles) above our heads.  ‘Orbit’ takes us on a spectacular journey above our planet seen through the eyes of the International Space Station.  Using NASA time lapse imagery, actual space to ground radio communications and a cinematic musical score this video is well worth a look.

If you haven't seen this one from 2012 before, I really hope you enjoy it and would love to know what you think :-)

I experimented with two things for this video. Persistent Meteors and dimmed Star Trails.

Magnetic Field of the Earth - June 2014
Launched in November 2013, Swarm is providing "insights" unprecedented about the complex workings of the Earth's magnetic field that protects us from cosmic radiation and bombardment of charged particles from space.

And so far, these data indicate that the Earth's magnetic field appears to have weakened substantially in recent years, about 10%.

Some measurements made ​​during the last six months confirm the general trend of weakening of the field, with the most dramatic declines concentrated in the Western Hemisphere.
