LoooSeR Posted January 21, 2016 Report Share Posted January 21, 2016 Heard about that on the radio here, in Russia. Father said "bullshit", i said "let's wait". Quote Link to comment Share on other sites More sharing options...
Belesarius Posted February 11, 2016 Report Share Posted February 11, 2016 Gravity waves detected for the first time. Pretty cool. http://www.cbc.ca/news/technology/ligo-gravitational-wave-1.3443697 Quote Link to comment Share on other sites More sharing options...
LostCosmonaut Posted February 15, 2016 Report Share Posted February 15, 2016 P/2016 BA14 (an asteroid which might possibly be a comet based on its orbital parameters) is going to pass .024 AU from Earth on March 13th. http://www.alpo-astronomy.org/cometblog/?p=1381 It'll stay pretty faint (but observable) if it doesn't show cometary activity, but if it does it could be pretty cool.

LostCosmonaut Posted February 23, 2016 Report Share Posted February 23, 2016 Alright, so 100 GW = 1*1011J/s. Applied for 10 minutes = 6*102 s gives you a total energy output of 6*1013 J. KE = mv2/2, if we set m = 100 kg, and cancel units, we get v = 1.1*107 m/s, which is about 3.7% of c. So pretty fast, but not relativistic, and that's assuming perfect energy conversion and no drag losses. Also, when you're accelerating protons in the lab, you don't have to worry about turning them into paste by accelerating them too hard, you don't have to take your energy source with you, etc. Sturgeon 1 Quote Link to comment Share on other sites More sharing options...

Belesarius Posted April 13, 2016 Report Share Posted April 13, 2016 Stephen Hawking, Mark Zukerberg and Russian Billionaire Yuri Milner are planning to send probes to Alpha Centauri. http://www.cnn.com/2016/04/12/us/breakthrough-starshot-space-probe-stephen-hawking-feat/index.html Not an achievement as of yet, but I'm glad to see rich and influential people pushing for more space exploration.

Sturgeon Posted April 30, 2016 Author Report Share Posted April 30, 2016 Updated Falcon variants payload chart; 28 tons to LEO is more than I expected for Falcon 9. Yep, they've really created something special with that rocket. The latest variants outlift anything without boosters in that class. Quote Link to comment Share on other sites More sharing options...

Belesarius Posted May 6, 2016 Report Share Posted May 6, 2016 This was apparently a really difficulty launch profile and they weren't actually expecting to land it. And Elon MUsk's twitter post. https://twitter.com/elonmusk/status/728459808270000128 LostCosmonaut 1 Quote Link to comment Share on other sites More sharing options...
LostCosmonaut Posted May 9, 2016 Report Share Posted May 9, 2016 Transit of Mercury today. Next one is in 2030s, which is fortunately much closer than the next Venus transit. Edit: and another Also, I was wrong, the next Mercury transit is in 2019. LoooSeR 1 Quote Link to comment Share on other sites More sharing options...
