I saw somewhere that someone was saying this is the last Dragon launch and they will move to Dragon 2 for subsequent launches can anyone confirm?

I thought it was the last use of a new dragon? subsequent launches will be reusing old dragons and now Dragon 2 manufacture can be stepped up.

Yes, they'll reuse existing Dragon 1s from now on. Although the cost of refurbishing recovered ones is about the same as a new build I read somewhere.

This was the last of the original 12 NASA ISS resupply missions, but the contract was extended first to 15 and now to 20 flights.

The first test flight of Dragon 2 isn't expected until March 2018 and will be unmanned.



This latest launch was also the first "Block 4" Falcon 9 first stage, which has uprated engines. The block 4 is in an intermediary version to the (wait for it...) block 5, which will have several more upgrades after their experience with recovered rockets.

What will be the launch escape facility now that NASA have decided Super DRACO is a no go??

They've only discounted the powered landing not the escape system

Okay. I read it as a total elimination from dragon.

I think they're eliminating it from the cargo version?

Yes, that's what Elon said during his keynote at the ISS R&D Conference last month.

He still thinks it would survive a launch problem with the rocket though, then come down on the parachute.


Also the legs have been deleted from the Dragon 2 design of course.

They ran a successful test fire earlier on the latest Falcon 9. This one is at Vandenberg in California.

They plan to launch on Thursday 24th August at 7.50 pm UK time, with a drone ship landing shortly after.

It'll be carrying the FORMOSAT-5 Earth observation satellite. whistle

Has there always been this amount of launch activity in the space Industry in recent years or have SpaceX really made a huge difference?

I'm pretty sure that SpaceX has upped the launch frequency as far as the US is concerned.

Next week's Falcon 9 launch will be "only" their 40th. It's fair to say that SpaceX have certainly shaken up the market already. Before them, there was no real need to innovate and bring the cost of launches down. It was quite a cozy situation with demand outsripping launch capacity.

As Elon Musk said 5 years ago, a circa $200 million Ariane V launch just can't compete with a $60 Falcon 9 one, even if the cost is split between 2 satellites. Especially at Ariane's leisurely 6 launches a year schedule.

https://www.youtube.com/watch?v=aK6gZ55VT50

The price for a comparable Atlas V launch has dropped from around $150 million to $110 million due to competition.

There's nothing wrong with the Ariane V & Atlas V and they've proven to be dependable systems. For some clients they're happy to pay extra for that reliability. However, competing on price opens the market for other, more adventurous clients that will actively opt for a pre-flown rocket to get into orbit at a lower price.

SpaceX currently have around 45% of the space launch business. It's predicted that next year they'll have 60%.

Hmm after the earlier resupply mission upset I thought the plan was to have the escape system available to recover those highly valuable goods??? [don't mean fiscially]

When the CRS-7 rocket blew up it was already 2 minutes into the flight. The capsule was thrown clear, but its flight computer hadn't been programmed to deploy the parachutes in the event of a launch emergency. so it plunged like a rock into the Atlantic.

Quite an oversight really, which hopefully they've rectified since.

CRS-9 has gone to McGregor for static fire testing, this is one of the two side boosters for the FH test.
Thaicom-8 and the new centre booster have already been test fired and waiting at the cape..

Looking real for a November test!

SpaceX's "baby" Raptor engine was being tested 5 days ago, here's the plume that it made!

I wonder if that's actually a full size one, rather than a one-third version.

Even a full size Raptor will be about the same size as a Merlin engine, so not that big really.
