  • Welcome to another episode of SpaceX in the news. My name is Kevin today

  • We're just gonna take a really brief. Look at the latest starship developments

  • Our main focus will be Commercial Crew and the other day's press conference that Elon Musk and Jim Bryden stein put on then we'll learn

  • a fascinating history lesson as to why an upcoming

  • Falcon 9 mission will launch to a polar orbit from the Cape instead of Vandenberg Air Force Base in California

  • Then we'll finish with today's honorable mention. Let's get into it

  • So again, not a whole lot to discuss today concerning starship updates

  • But that doesn't mean that nothing is happening at the Boca Chica and Koko sites the launch pad for the Marquand prototype is still receiving

  • major upgrades in preparation for the 20-kilometer

  • Flight that should take place within a month and pad 39a is undergoing its own upgrades for future starship launches

  • furthermore the mark 2 prototype that will utilize the launch pad has recently received external pipe egde the next starship update elan puts on will

  • Include more information concerning the plan for point-to-point transit on earth this week NASA Administrator, Jim brightenstein and SpaceX

  • CEO Elon Musk put on a press conference at SpaceX headquarters in Hawthorne, California

  • With the sole intent to promote the Commercial Crew program just prior to the event

  • Jim was given a tour of the facilities and NASA took some pretty nifty pics

  • Including an image of the crew Dragon capsule that will be the first to take American astronauts to space early next year those two

  • Astronauts Bob and Doug were in attendance as well and despite NASA's Flintstones qualitystream

  • CNBC managed to do us a solid with what they captured

  • so here's just a quick little run through of all the

  • Interesting moments from the media briefing first the status of crew dragon and was to come

  • We have a static fire that is going to be happening in short order.

  • We have a high altitude abort test that will be happening in short order.

  • We've talked, even today. That we could see as many as 10 drop tests between now and the end of the year.

  • We're hoping to have the first successful mark 3 drop test within a week or two.

  • There will be steady cadence of tests thereafter.

  • Second, Elon commented on the crew dragon demo one capsule that exploded last April

  • And to be totally frank, if there hasn't been some hardware that blew up on the test stand, I don't think you've tested it hard enough.

  • That's the reality. You've got to push the envelope. Find out where the outer issues are. Then address all the corner cases.

  • Jim said that the explosion of the demo one capsule gave him confidence in Elon Musk and SpaceX because the very cause of the explosion

  • The propellant was the very thing that Elon said he was worried about when Jim became administrator

  • Elon Musk said to me, he said that's the biggest concern, that's what we need to worry about.

  • And I will tell you, if we look at the catastrophic failure that happened back in April, he was right.

  • And that gives me confidence. And that is why we test.

  • Doug and Bob were appreciative of SpaceX's transparency concerning the explosion as we all are

  • Any of these failures as they go forward, giving us insight and sharing that understanding as we go forward

  • Has been a part of what makes me so comfortable with this team kind of going forward

  • And I just really appreciate how much insight we've been able to have and how quickly we've been able to have it

  • in each of these cases as these cases when something like this comes up

  • We all know I love parachutes so imagine my excitement when they started talking about the new Mark 3 design

  • The biggest difference between the mark 2 and mark 3 is going to much stronger lines in the parachute

  • So going from essentially nylon to zylon. The strength of the lines is about 3 times that of nylon.

  • And then there are some changes to the stitching pattern, where the lines connect to the canopy.

  • You've got a stress-concentration. So you wanna have exactly the right [inaudible] to spread the load and the stress-concentration where the lines meet the canopy.

  • Jim was asked about William Gerstenmaiers permanent replacement for associate administrator for human exploration and operations

  • We opened the aperture very wide initially and started to narrow it down, but we are not ready to announce who that person is

  • But I will tell you, that announcement is not months away, it's weeks away. And that's a day we're all looking forward to

  • And finally Jim wanted to clarify his position and NASA's position on starship

  • I want people to make no mistake. That NASA has an interest in seeing Starship be successful.

  • We have been a partner on Starship, a non-exchange of funds kind of partner, when it comes to aerodynamics. And when it comes to testing and test facilities.

  • Crew dragon is currently expected to launch ports demo to mission with Bob and Doug on board in the first quarter of

  • 2020 NASA has been training a lot lately for this upcoming mission to the International Space

  • Station in a view from the demo one capsule during liftoff was recently shared as well the Falcon 9 rocket for the Argentinean Space Agency's

  • Sawa comm Earth observation satellite will no longer lift off from Vandenberg Air Force Base

  • But instead will move to the Cape for its launch

  • No earlier than February

  • 2020 while I'm not sure why it could be due to California's known hostility towards Vandenberg's commercial launch manifest

  • But what makes this move so surprising is that this particular satellite will be placed into a polar orbit and polar

  • Trajectories haven't launched from Florida and decades see a 1960 tensions were peaking between the u.s. And Cuba during the Cold War

  • In fact, just a year later

  • the Bay of Pigs invasion would take place, but that

  • November a Thor able star launch vehicle attempted to place a military spy satellite in a polar orbit from Cape Canaveral

  • Unfortunately, the booster malfunctioned and caused a slight diversion in the flight path

  • The rocket was manually detonated as standard protocol dictates

  • But an unlucky Cuban cow was prematurely slaughtered when it caught a piece of falling debris

  • And you can imagine the following drama that in student between the two nations during such a delicate time in history

  • And so the u.s. Decided to end polar orbits from the Cape until now, but now it's time for today's honorable mention

  • All right, we're back with yet

  • another segment of Richard Branson's Virgin

  • Company only this time we'll be discussing virgin orbit and their mission to be the first private company to send cube SATs to Mars as

  • Virgin prides himself on launching Rockets differently than most other space agencies and this new Martian endeavour was reportedly inspired by NASA's insight mission

  • Well, that's all I have for you guys today

  • Thank you so much for tuning in and until the next one
