SpaceX Falcon Heavy Boosters Return Safely Simultaneously

When I was a kid, I remember sitting in front of the 25 inch tube TV in my parents' living room watching Apollo space capsules splashing down in the ocean and US Navy divers jumping out of helicopters in wet suits to attach lifting cables to the outside of the floating capsules.  It had always fascinated me, and I've seen Mercury, Gemini, and Apollo re-entry capsules in Chicago at the Museum of Science and Industry, in Washington DC at the Smithsonian, at the San Diego Air and Space Museum in Balboa Park.  Those capsules exited the atmosphere, and returned, carrying live astronauts, and surviving re-entry through he atmosphere, and the heat and pressure scars on the surface of the capsules was always jaw dropping to me as a kid, as a teen, and as a young adult that we, as puny humans, could design and build and launch something that was so tough it could survive re-entry and return the astronauts back to terra ferma safely.

Then today, South African immigrant Elon Musk's company SpaceX launched the Falcon Heavy as a test flight for future Mars missions, making it the largest rocket (3 million pounds) launched since Apollo moon missions more than 40 years ago.  Yes, SpaceX has launched and recovered boosters before. Sometimes on remote controlled barges, sometimes on land. But they had not done a double booster return yet, and watching today's double simultaneous landing was... amazing... jaw dropping... awe-inspiring... remarkable.  See here:


Sure, the rocket's  "payload" was Elon's personal Tesla Roadster convertible, being driven by a mannequin in a space suit, and outfitted with 3 cameras that have been giving fantastic views of the car and the Earth as it heads into orbit around the Sun and a rendezvous with Mars in about 6 months... and that's cute, and stylish, and amusing, and FAR BETTER than launching a dummy payload of bricks or steel or something really boring (but safe).  Elon had given the launch a '50 to 66% chance of success', setting realistic expectations.  The boosters came back safely, and beautifully.  The main core malfunctioned after separating from the payload at MACH 15, and did not make it to the remote controlled barge in the middle of the Atlantic Ocean as planned... but 2 out of 3 safe returns for usable rockets is not bad. And I anticipate, it will only get better with more practice.

Going into space is hard.  It's not easy nor simple, and few nations have done it successfully.  Fewer companies have done is successfully, and Only One has returned two booster rockets, simultaneously, to a precise launch pad, without using heat sheilds, the ocean, US Navy divers, or parachutes... very impressive indeed!

Balboa Park Botanical Garden

On Sunday, Dr Desert Flower and I had zero interest in watching the Superbowl since it was the New England perennial cheaters against the Philadelphia obnoxious fans underdogs.  [Note: I clearly state "cheaters" not because of just 'deflate-gate', but because of the pattern over years of coach Bellicose's reign, where he sent spies to opposing teams' training camps to video tape their practices, hired professional lip readers to spy on opposing teams' offensive and defensive coaches to gather intel on what plays were coming next, and generally played very dirty, making every under-handed, sneaky, below-board move possible].  Not wanting to spend time in front of the TV watching the glorification of two teams we despised, we decided to go somewhere that normally would have many people, but hopefully would have Much Fewer persons and be far less crowded than than usual.  We decided upon Balboa Park's Botanical Garden, as we'd never been there before and it was less than an hour's drive away.

Much Smaller than Phoenix's Desert Botanical Garden, the Balboa Park garden is cute, compact, a pretty little spot to visit.  It's perhaps 5% the size of Phoenix's botanical garden, but of course much cooler.  The weather was in the mid-to-upper 70s (Fahrenheit), with low humidity in the 30% range, with gentle breezes of 5 mph every now-and-then.  Quite pleasant.  Crowd-wise... it was a different story.  We arrived around noon, and could only find parking in the vast lot behind the Air and Space Museum in Balboa Park.  Not a long walk, but a good 1/2 mile or so to get to the Botanical Garden.  By the time we left 90 minutes later, that large parking lot was jammed full with cars circling like sharks looking for parking spaces.  The crowds were international.  I heard Spanish, Italian, Russian, Czech, Hindi, Mandarin, Japanese and Thai being spoken as we walked through the park and passed various families; International visitors who Also could not care less about the Superbowl spectacle.  We tried eating at 2 of the cafes inside the park and found 30 and 45 minute waits... and not being British, I don't queue very well, so we headed over to Banker's Hill and had a delicious leisurely brunch at Parc Bistro.

Next year, when two teams are playing that we are equally apathetic about, we'll head out to a remote national park and enjoy the serenity and tranquility, devoid of human interference.  = )
