Some of the debris from a collision may end up in an orbit with a higher apogee, perigee will necessarily still be at or below the altitude of the last collision and will be subject to some of the same low-orbit aerodynamic drag that starlink satellites experience; passes through lower altitudes will apply drag that will first drop the apogee and will then eventually cause the debris to reenter.
starlink satellites are in low orbits and will deorbit in a few years at most if bricked; to stay in orbit, they use ion thrusters to counter drag from the very uppermost reaches of the atmosphere.
I (an American) once arrived in a hotel room in Finland, sleep deprived after a long couple flights, flipped on the TV and saw a game of Pesäpallo. Made me wonder what I was seeing and what might have caused me to hallucinate..
It's not a scam. It's the difference between annuities (longevity insurance) and savings.
If you wanted all pensions to provide a death benefit in addition to the annuity you'd need to either significantly reduce payouts to the living or significantly higher payments into the pension fund.
Smart bomb targeting is more of a subset of the tech required for precision landing.
Smart bombs just need to get to the target coordinates. A reusable rocket needs to get there with zero velocity, while pointed straight up, with minimal pitch/yaw/roll.
Pretty much all of the barge landing failures shown in "How Not to land an Orbital Rocket Booster" would have been accurate enough to put a warhead on target.
They haven't stopped but they don't happen immediately.
Detailed census records are published 72 years after they were collected; the last release (of 1950 census data) came out in 2022; the next one should be published in 2032.
There is spare capacity on the Crew Dragon for an extra astronaut or maybe two on return. They'd rather not have to use it but NASA took steps to enable it when Soyuz MS-22 suffered a coolant leak in 2022 and had to be returned empty.
There are normally-open air-tight hatches between modules. Various utility connections and air ducts are normally run through the open hatches so it would take a bit of work to disconnect these connections before they could be closed.
Not exactly something you want to be doing under time pressure.
"The air leaks escalated on Friday from a pound of air per day to two pounds, according to a senior NASA official who asked not to be named.
Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikayev were using a saw to break into an area where they believed they could access the crack leaking air, the NASA official said.
NASA officials disagreed with this method, the NASA official added, prompting mission control in Houston to order safe-haven procedures."
Several of the US modules were built in Europe by Thales Alenia Space and were transferred to the US in exchange for the US launching the European modules on the Space Shuttle.
Their terminology is odd. The thing you move while playing is generally called the hand slide. There's nearly always a separate tuning slide located in the crook of the bell section.
(Some relatively rare instruments like the Shires Alto do "tuning in slide" with a mechanism for fine adjustment in the hand slide).
If you're also moving the tuning slide in the middle of a piece you're probably a bass trombonist doing the now-impossible glissando (see https://www.youtube.com/watch?v=fWJPeA_1g48) in the Bartok concerto for orchestra.
