Reply to comment by rocketsocks in Rocket Lab targets $50 million launch price for Neutron rocket to challenge SpaceX’s Falcon 9 by cnbc_official

Until now SpaceX is the only provider who lands and reuse rockets. They only one who knows how to do that. Do you know how I call it, when someone else says that it's going to do it better? I call that BS. Rocket Lab should first attempt to land a rocket successfully, then relaunch it, and then they can talk. Until then...

Yeah,it does mean that exactly. Starship is about to launch in less than 2 months and then cadence will increase. Neutron is at minimum 2 years away, possibly 3-4, and then a few flights until they start landing attempts, another few to land, and another 2 years to relaunch that and then another 2 to increase launch cadence. Good luck.

>There is still no known threat

Known being the key word. We didn't know about this thing until it was on top of us.

Risks are low but the outcome could be really really bad.

Reply to My camera setup on the International Space station. More details in comments. by astro_pettit

Black and white self-portrait in the Cupola aboard the International Space Station. I was setting up a few cameras for nighttime timelapse imagery. I stretched a cloth across the hatch opening to eliminate stray light from Node 3 (the Cupola is attached to Node 3). There was a small opening just for my head so I could operate the cameras. I had the window shutters closed for this photo since it was daytime and the bright sunlight would spoil my desired lighting effect. If you can't tell, I went to great lengths for my craft. Over my missions I have captured hundreds of thousands of photos. This one was taken during Expedition-31 to the ISS, in 2012.

More orbital astrophotography can be found on my twitter and Instagram profiles, for those interested.

Rocket Lab doesn't know yet how to land and reuse rockets. It took SpaceX almost 10 landing attempts, and when they did land it another 2 years to reflight that booster. And many years after that to increase cadence. Rocket lab will have to get the same learning period and they move slower than SpaceX. And Starship will fly at minimum 2 years before Neutron 1st launch attempt. Where exactly do you see them have time to catch up?

You guys know about Tunguska? It was thought to be only 56-foot-wide (50 m) asteroid. It flattened trees over 830 square miles when it burst in the air. That's flattening an entire area 28 miles by 28 miles. And that's on the lower end of the range for DZ2.

Could easily kill millions of people in an instant.

Kinda scary that there are objects like this that are floating around and that we only notice at the last minute.

The operative word is could, as in, given the correct positioning, you COULD make this occur. It’s not saying “you will make this occur, given any possible positioning/rotation.”
