After the USSR and USA, the third country to design and build its own satellite was Canada. The Alouette 1 was launched by NASA in Sept. 1962. It was designed to study the ionosphere. With a 600+ mile orbit, it is expected to stay up for 1,000 years. However, it was switched off in 1972, ten years and one day after launch. Those antennae are 125 feet tip to tip.

That must be Gus Grissom's capsule on the ocean floor. It was deeper than the Titanic!

The Space-X Starship under construction in Texas. Shiny stainless 301 is a lot cheaper and more suitable for this work than carbon fiber, says Elon.

The rockets developed by the Jet Propulsion Laboratory, the first satellites, the moon landing, missions to Mars....all made possible with computers. Except that back then the 'computers' were women. All the math involved for trajectories, launch weights, orbits or even the amount of exhaust velocity and thrust that a particular engine nozzle would generate were all figured out by these women; the rocket girls. Live and in real time, during those early missions and armed with pencils and graph paper, their brains did all the calculations.

(Picture from 1953) There were no computers for engineers to jump to for results back then, this group is responsible for all the hard work!

Anyone interested in space and NASA should go read this book:

How about a balloon over 400 feet wide?

NASA's launch to Mars blasted off today. They used the United Space Alliance Atlas V rocket.

Something different this time, it actually has a flying drone on board. This will be the first time for such a vehicle on another planet. Getting a drone to fly on Mars is difficult, the thin air is like flying at 100,000 feet on Earth. Making it as light as possible, taking advantage of the lower Mars gravity, having extra large rotors that turn much faster than usual plus hardening the craft against extreme cold were all challenges to overcome.

Isn't Space-X (Demo-2) Crew Dragon capsule supposed to be coming back

reentry & recovery supposed to be televised

I think I heard, undocking broadcast "farewell" starts from the ISS
9:10am EDT Sat. Aug. 1 actual undocking is like 7:34pm EDT
Sunday Aug. 2, some 19+ hrs later appr. 2:42pm EDT, in the Gulf buy Florida
SPALSH DOWN
Science or Discovery networks
(didn't find it in the listings "yet", Comcast sucks)
