RIP Pierre and Sasha. From our last correspondence:

I will effort to get as much of this on TV to help Ukrainians in every way possible. Keep Smiling.

@FedorovMykhailo Starlink service is now active in Ukraine. More terminals en route.

An explanation for my non-IT followers is in order.

Digital devices often store numerical values in data cells called a "double" (two times 8 bits).

The largest number it can store is 2¹⁶-1 = 65535... which rounded down to the nearest hundred is 65500...

@DrEricDing 65500 microsieverts is just under the 16-bit integer overflow limit, it's most likely capped at that on the website - a friend said that

WATCHING—elevated radiation ☢️ levels observed at #Chernobyl reactor site—not super high yet but 65 μSv (65k nSv) is elevated above normal. There was reported shelling around Chernobyl between Russian & Ukrainian forces. Praying this doesn’t get worse.🙏

Our submission for @RocketContest's Marketing Competition was just wrapped up! You can watch it here: https://t.co/m3XZVzAoQd

We recently found out that we made the top 100 teams in @rocketcontest and will be going to nationals the first year of us participating in TARC! We want to thank @rockwoodschools and @MarquetteStangs for their support and as well as our teacher sponsor Dr. Farrar! (1/2)

[Astral Orbit @realastralorbit]

Great launches abound! In the meantime, we'd like to thank @RocketContest and its sponsors, including nearby @Boeing and their staff for their support. We'd also like to thank @StLouisRocketry for their time and guidance during the qualification flight process. Cheers!

[Astral Orbit @realastralorbit]

Just finished both of our qualification flights for #rocketcontest. We did absolutely amazing and we hope other teams have had great success as well.

Here's a link to our on-rocket footage while doing one of our qualification flights: https://t.co/XKkaqJvIqm

@leahtexter Remember, 2 electron domains is linear, 3 electron domains is trigonal planar, and 4 electron domains is a tetrahedral. These are molecular structures; however, geometry can change due to lone pairs, so make sure you read up on that. You also need to know bond angles.

[ARK @ARKinspace1]

@leahtexter https://t.co/30xMA7Gb85 Use these videos and see what you want to see. Bond hybridization is pretty easy. Basically if it has 2 electron domains, it is sp hybridization. If it is 3 electron domains, then sp^2. 4 electron domains is sp^3.

@leahtexter That equation is used to find the pH at the equilibrium of a buffer solution. I would suggest watching this https://t.co/EGo2Bi2msL ♥️

Wish you luck, I'm taking it tmmrw too!

@sm_rocketry I remember them saying that an apollo style mission was allowed and we went with that when we designed our rocket.

[ARK @ARKinspace1]

@sm_rocketry I meant to say "Don't", my bad. Also i just wanted to double check since we didn't ask them.
