Reply to NASA’s DART data validates kinetic impact as planetary defense method | DART altered the orbit of the asteroid moonlet Dimorphos by 33 minutes by mepper
“Altered the orbit of the asteroid by 33 minutes “
Can someone ELI5 that for me? Does “33 minutes” translate to feet, yards, miles?

Reply to I’m building a border around a playground with landscape timbers, and wanting to secure it with something other than rebar. by _aPOSTERIORI
Out of curiosity, if the rebar is completely hidden within the 4x4's or 6x6's, what is your rationale for not wanting them? They're tailor made to secure a timber wall.

Reply to Latest video of the Ingenuity Mars Helicopter kicking up dust and taking off for Flight #47. Ingenuity is well beyond its warranty at this point. The video was captured by the Mastcam-Z imager aboard NASA’s Perseverance rover on March 9, 2023. by ICumCoffee
So how does this helicopter differ than a similar helicopter that would be used in Earth? With Mars’ thinner atmosphere I would imagine that some alterations would need to be made to sustain lift.
