Thanks to Everyday Astronaut for the coverage and the contagious enthusiasm.
I’ve been a little caught up in day-to-day living and not posted anything about all the cool stuff going on in space right now.
Mars is getting new robots!
A launch window that only happens every 26 months means it’s the perfect time to head to Mars! The United Arab Emirates, China, and the United States all too...
And Endeavour is bringing Bob and Doug home this weekend!
In about two hours, if the weather allows, SpaceX will be launching two astronauts in a Crew Dragon capsule to the ISS for the first time. This is a big deal.
Nine years ago, I watched the last shuttle launch with my kids. The oldest was three years old, and the other was one, so they have no recollection of this. Since then, they have grown to awareness in a world in which the US is incapable of launching its own astronauts into space.
This launch means that will now change. But this launch goes beyond just returning human-launch capability to US soil. That’s cool and all, but focusing on it is a bit short-sighted. This launch marks a turning point in humankind’s relation to space.
SpaceX, with its rapid development of Cargo Dragon, Falcon 9, and Falcon Heavy, has managed to decrease the cost of getting things to space by orders of magnitude. When it is possible to launch lots of stuff cheaply, we’ll launch lots of stuff. Now, with Crew Dragon, SpaceX is going to do that for humans. And when it becomes possible to launch lots of humans cheaply, we’ll launch lots of humans.
Lots of humans and lots of stuff in space means, well, it could mean anything. But mostly, it’s a critical step toward becoming a space-faring civilization. And that’s why this is a big deal.
A year and a couple months ago, I wrote about the SpaceX Demo-1 mission and why it was so important. That mission successfully sent an uncrewed Crew Dragon capsule to the ISS and returned it to Earth. Then, a little over a month later, a Crew Dragon exploded unexpectedly during a static fire test of its abort thrusters. This delayed a crewed mission, while SpaceX investigated the cause and made corresponding changes to the capsule. As is often and quite accurately said: space is hard.
But the wait is over. Wednesday afternoon (May 27, 2020), at 4:33 EDT, SpaceX will launch Demo-2 to the ISS. Aboard that capsule will be two astronauts, Robert Behnken and Douglas Hurley, the first launched from US soil since the final shuttle launch (STS-135) in 2011.
Keep your eyes up. Times are weird right now, but we will get through this pandemic. And when we come out the other side, we will be well on the way to becoming the space-faring civilization that we are destined to be. Wednesday’s launch is a big step on the path. I urge you to watch the launch, if for no other reason than as a reminder that history is bigger than the mess we’re in right now.
Can you dock a Crew Dragon to the ISS?
Take your time. Attitude first, then position. Take your time. Equal and opposite. Always.
SpaceX abort test delayed until tomorrow (1/19) due to weather at recovery area.
SpaceX will conduct an inflight abort test of Crew Dragon tomorrow morning. As the Falcon 9 reaches max-Q, it will shut off its engines to simulate a worst case failure. This should trigger the Crew Dragon to separate from the rocket and fire its own Super Draco engines to get away from the failing rocket. Once clear, Crew Dragon will pop its parachutes and land gently in the Atlantic. This should be quite a show and is the last major milestone before an actual crewed launch.
Some details on SpaceX’s Mars plan and the issues they are working on.
Dr. Phil Metzger posted an epic 48 tweet thread on Twitter explaining why megaconstellations (e.g. SpaceX’s Starlink) are inevitable, as is their eventual demise as better tech comes online.
Looking at the evolution of life, from single celled organisms to bipedal apes rapidly outgrowing the planet, as the exponential growth of information is a novel (to me at least) approach and provides an interesting perspective.
“I would bet that if we find alien civilizations somewhere else in the galaxy, or in a galaxy far, far away, we will discover that they ALL developed megaconstellations right before they got industry off their planets & divorced their information systems from their biosphere.”
This is wild stuff and well worth a full read.
Ostensibly about the SpaceX Raptor engine, it’s really so much more. If you’ve ever had a hankerin’ to learn more about rocket engine design, Everyday Astronaut‘s latest video is a great place to start.
