Title: Cheap Astronomy – Dear CA 087: Periodic table & Props up a Rocket

Organization: Cheap Astronomy


Description: Cheap Astronomy investigates the periodic table and then props up a rocket.

– Why is the abundance of elements not ranked by atomic number?

So, the most abundant element in the Universe is hydrogen, atomic number 1, the second most abundant element is helium, atomic number 2. But are lithium, atomic number 3, and beryllium atomic number 4 the next most abundant? No – not even a little bit. After helium it’s oxygen, atomic number 8, carbon, atomic number 6 neon, atomic number 10 and then iron atomic number 26.

– What’s involved in ‘clearing the tower’

The announcement that (insert mission name here) has cleared the tower mostly derives from NASA mission protocols and some Hollywood embellishment. With most human crewed missions NASA Launch Control in Florida has been in charge of the mission up and including the launch, which may include mission aborts due to bad weather or even launch malfunctions that might require activating the escape system that rescues the astronauts.
