Oh yeah! Check out what they're doing with "Ms. Tree" (formerly Mr. Steven). It's freaking wild. The fairings cost $5M or $6M for the pair, almost 10% the cost of a Falcon 9. Recovering them is going to really add up once they nail it.

SpaceX caught both fairings on their most recent launch. First time they've managed to catch both of them.

They're remotely controlled as well. They can actually fly (falling with style). The boat and the fairings both steer into a central location. It's wild.

From today the attempts to launch for Mars begin!

It was one of those things for which you could register and have a boarding pass, I checked and I still have mine, so I'm going to Mars!

Tim Dodd is a great watch.

I have to say, I really miss Space X's production quality when watching a launch from any other organization. They give us beautiful HD footage (in real time) the entire way up, and then they followup it up with gorgeuos shots of stage separation and fairing deployment. This NASA live stream is okay, but no one else really comes close.

So its confirmed that @CommanderMLA is flying the @Axiom_Space@SpaceX#CrewDragon tourist mission with Director @DougLiman & Tom Cruise. One seat still to be filled. They are to launch in October, 2021.

I mean, bring it on! Even if it's just a documentary about Tom going to space i'm so up for that.

That is an amazing shot for sure, I saw the guy's post on reddit and he explained all the planning that went into preparing for that shot.

This is a rare type of transit. The ISS when it transits the moon is vary rarely illuminated like this, and when it is, it is usually too low on the horizon to get decent details. So I had to make sure to travel to the location of the transit (a space about 200 feet wide and about 10 miles long) but it happened to pass thorugh mostly private property. Thankfully I found a public road that left me a good spot to shoot it. I recorded video at 150fps at 2000mm with a special type of camera for this event to get this level of detail, and timed my shots down to the second to make sure I didn't miss it.

Just watched the launch live with my daughter. I'm so glad she's into space. She could even see the trails from her window. amazing accomplishment by space x. Still blows my mind how they're able to reuse the capsule and rocket.

I'd hate to be the manager that signed off on this stage of the project:
https://spacenews.com/human-error-blamed-for-vega-launch-failure/

WASHINGTON — Arianespace executives said Nov. 17 that the failure of a Vega launch the previous day was caused when the rocket’s upper stage tumbled out of control due to incorrectly installed cables in a control system.

In a call with reporters, Roland Lagier, chief technical officer of Arianespace, said the first three stages of the Vega rocket performed normally after liftoff from Kourou, French Guiana, at 8:52 p.m. Eastern Nov. 16. The Avum upper stage then separated and ignited its engine.

However, “straightaway after ignition” of the upper stage, he said, the vehicle started to tumble out of control. “This loss of control was permanent, inducing significant tumbling behavior, and then the trajectory started to deviate rapidly from the nominal one, leading to the loss of the mission.”

Analysis of the telemetry from the mission, along with data from the production of the vehicle, led them to conclude that cables to two thrust vector control actuators were inverted. Commands intended to go to one actuator went instead to the other, triggering the loss of control.

“This was clearly a production and quality issue, a series of human errors, and not a design one,” Lagier said.

Damn, as someone who cables things at work, I've definitely criss crossed cables before to some devastating effect... not quite like that though.

This is a bummer. I knew that it was structurally unsound. They'd just announced that it would be decommissioned due to safety concerns. Didn't think it'd fall apart so quickly, though.

Long before they CGI'd Pierce Brosnan onto the thing, James Burke climbed around up there to conduct a science experiment. The man sure as hell knew how to shoot impressive sequences.

I know some of these words!

https://www.rt.com/news/508319-oxygen-fuel-salty-water-mars/

Engineers at the McKelvey School of Engineering at Washington University in St. Louis developed a patented brine electrolysis system that not only works without the need for purified water but actually performs better thanks to the saltiness of the input water.

Salty water isn't potable, and the standard method of separating oxygen from hydrogen contained in water, electrolysis, is notoriously cumbersome and expensive here on Earth, making it orders of magnitude more expensive on the Red Planet.

On Mars, water that isn't frozen is extremely salty, which lowers its freezing temperature but restricts options for hydrolysis, until now.

“Our Martian brine electrolyzer radically changes the logistical calculus of missions to Mars and beyond,” says lead researcher Vijay Ramani. “This technology is equally useful on Earth where it opens up the oceans as a viable oxygen and fuel source.”

Ramani and his team operated their device, which employs custom-engineered ruthenate pyrochlore anodes and a platinum on carbon cathodes, in a simulated Martian atmosphere at -33 degrees Fahrenheit (-36 degrees Celsius) to produce both oxygen and hydrogen.

The disaster buff in me is quite happy they have footage of its collapse. That they were inspecting that very anchor point when it failed is pretty interesting. Not suspicious, mind you, they knew there was a serious problem there, but certainly fortuitous.

Chino · « **Reply #1644 on:** December 03, 2020, 01:33:16 PM »

I think the footage of all the cables crashing down was a controlled demo.
