All good for Friday

perfect gif!   beats watching the 2 minute video when more then half of it is like nothing lol

also rofl at the debris getting blasted out of the flame trench, whatever it was lol

3 1/2 hours

Seems Blue Origin landed again too!

Just watch though how it hovers at the very end for a few seconds before landing. With that much margin for error, they should be able to just keep launching and landing without a problem.



Not big enough for orbit or payloads, but space tourism could be just a few years away.

This is why I need a telescope.

Greetings, it's been nearly a year since I've posted here and updated this!

 Since then (I think) my skills have gotten better with working the camera and stuff Here's some new images of mine.

 

 Jupiter (With the Great Red Spot) visible in this photo, it was the first time I've personally seen it with my own eyes. It was great. I think this is my best image thus far.

 

 

 Saturn - Taken in Black and White earlier this year!

 

 

 Moon with nice crispy craters!

 

 

 Sun! (With proper filter, never ever look at the sun with a telescope without a proper filter! Blind in a second )

 Sun spots visible in this too!

 

 

 More to come!

Plan to send probe to Alpha Centauri w/ Stephen Hawking - NeoGAF

$100 Million Plan Will Send Probes to the Nearest Star
 Funded by Russian entrepreneur Yuri Milner and with the blessing of Stephen Hawking, Breakthrough Starshot aims to send probes to Alpha Centauri in a generationhttp://www.scientificamerican.com/ar...-nearest-star/

For Yuri Milner, the Russian Internet entrepreneur and billionaire philanthropist who funds the world’s richest science prizes and searches for extraterrestrial intelligence, the sky is not the limit—and neither is the solar system. Flanked by physicist Stephen Hawking and other high-profile supporters today in New York, Milner announced his most ambitious investment yet: $100 million toward a research program to send robotic probes to nearby stars within a generation.

 

“Breakthrough Starshot,” the program Milner is backing, intends to squeeze all the key components of a robotic probe—cameras, sensors, maneuvering thrusters and communications equipment—into tiny gram-scale “nanocrafts.” These would be small enough to boost to enormous speeds using other technology the program plans to help develop, including a ground-based kilometer-scale laser array capable of beaming 100-gigawatt laser pulses through the atmosphere for a few minutes at a time, and atoms-thin, meter-wide “light sails” to ride those beams to other stars. Each pinging photon of light would impart a slight momentum to the sail and its cargo; in the microgravity vacuum of space, the torrent of photons unleashed by a gigawatt-class laser would rapidly push a nanocraft to relativistic speeds.
 Deployed by the thousands from a mothership launched into Earth orbit, each nanocraft would unfurl a sail and catch a laser pulse to accelerate to 20 percent the speed of light—some 60,000 kilometers per second. Using a sophisticated adaptive-optics system of deformable mirrors to keep each pulse coherent and sharp against the blurring effects of the atmosphere, the laser array would boost perhaps one orbiting nanocraft per day. Each laser pulse would contain as much power as that produced by a space shuttle rocketing into orbit.

 

I want to believe.

If it actually happens, that'd be swell.

Hardest part seems to be making the craft strong enough to send back the data.

I don't like this plan.

ESA Science & Technology: Venus Express' swansong experiment sheds light on Venus' polar atmosphere

so apparently venus has frozen poles..  wouldnt it make it a hell of alot easier to land?

What's the temperature on land though?  The paper referenced was talking about the atmosphere.

it doesnt say,  but even having the cooler atmosphere would make probes last longer going down,  any little bit helps.  

JCSAT delayed a week,

on that note, should we have a dedicated spaceX thread? lol

I don't think we should have a dedicated spacex thread since the science thread already isn't that active.

Im on team venus.


Mars is a lost cause. It lost its molten core a long yime ago. The planet is dead.

It just needs some mouth to mouth resuscitation.  
And methane factories, and some water.  And some oxygen.  

Venus meanwhile, needs some O2.  A lot of O2.  And lot less CO2, if you catch my drift.  
And less fire.  
Seriously that place is hot.

Alll we need to do is stear o2 rich astroids into the planet. You get your water and a cooling system. Thow some tree seeds an grass all over and we are good to go.

dang it. When looking i discovered that venus is missing a magnetic feild too. The venus dream is dead.
