Fall 2017 - a busy and exciting time for SpaceX

Sprinkled into the SpaceX launch manifest for this fall, and the first quarter of 2018, are two big milestones: the Falcon Heavy and Crew Dragon demos.

Also this month, SpaceX will once again have two back to back missing with the
SES 11/EchoStar 105 mission launching from Kennedy Space Center on the 7th, and the Iridium Next 21-30 mission launching from Vandenberg Air Force Base on the 9th.

SpaceX has a very busy launch schedule - 8 possible launches before year end

SpaceX appears fully recovered from it's single mission failure last year. They have managed several landings - first at it's new landing site at Cape Canaveral and then at sea - a much more difficult task, but an important one as not all missions are able to send the rocket all the way back to the cape. Landing the Falcon 9 rocket has always been a secondary mission objective - but a very important one in support of SpaceX's reusable rocket goal.

Rocket reusability is not only important for its cost savings, but also for the ability to shorting the time between launches. Even now the company is turning out missions faster than has ever been done before. And with the current schedule it will be launching multiple rockets in a single month. Here is the current launch schedule (with a lot of the exact launch dates still TBD):

Sept. 3	Amos 6
Sept. 19	Iridium Next 1-10
October	SES 10
October	EchoStar 23
October	Fermosat 5 and Sherpa
November	SES 11 (EchoStar 105)
November	Falcon Heavy Demo Flight
Nov. 11	CRS 10 (SPX 10)

Even with the their track record of quick turn arounds, this schedule would not be possible if all of the launches were from SLC-40 at Cape Canaveral. But with some flights out of Vandenberg AFB, and Falcon Heavy launching from the reconfigured SLC-39A at Kennedy Space Center, it could just happen.

Speaking of Falcon Heavy, with several rockets having been successfully landed now, it is what I'm looking forward to next (and I'm sure I'm not alone). Falcon Heavy has been anticipated for some time now. And had the big rocket just made a successful flight and ended up as the foundation of a new reef in the Atlantic, I would have been thrilled. But with the current landing success rate - and the presence of the landing complex - the possibility of the three Falcon 9 rockets separating and each landing itself autonomously is a real possibility. Would that be a sight to see!

Then what? We still have the manned Dragon 2 as well as the new Raptor engine (with greater power and re-useablity) to look forward to. And with these the company truly will be on course toward its big, red goal.

Next up for SpaceX - Pad Abort Test for Dragon, Tomorrow (May 6th) [Updated]

Update: May 6th. The Pad Test was successfully executed this morning.  The video from the Lifestream broadcast is below.

Before getting into the subject of this post, I'd like to acknowledge that this blog has become very SpaceX centered. That wasn't the intent - and still isn't - but it seems that SpaceX news fills the limited amount of time I have to devote to blogging. And they are doing such innovative and imaginative work that deserves to be shared. I do follow other commercial space companies, as well as NASA and other space agencies, but its likely that something extraordinary would have to occur with them in order to be shared here at this point.

On with the post.

With the Thales (TürkmenÄlem) mission complete, and the next launch scheduled for June, SpaceX will squeeze in the first test of the escape system for the human rated Dragon, now dubbed "Crew Dragon" in SpaceX's news release.

This first test is the Pad Abort Test, which tests the spacecraft's emergency crew escape capability for an emergency that may occur while the rocket is still on the launch pad. An upcoming second test will test the escape capability from an in-flight rocket.

While these tests may not seem as exciting as full launch - especially one that attempts to drop the Falcon rocket onto a small floating landing pad - it is actually a very difficult process with some very impressive metrics. For example, Dragon's eight SuperDraco engines will produce 120,000 pounds of thrust to propel the spacecraft 328 ft (almost 100 meters) in 2 seconds, and 1/3 mile (more than half a kilometer) in just over 5 seconds.
To put that into perspective, that's just about the same as the national record for the 1/4 mile (drag race), which is currently 3.701 seconds. One hell of a ride for sure!

Another point of interest is that SpaceX is attempting to improve on the traditional, familiar escape "tower" that was stuck to the nose of spacecraft from almost the beginning of the U.S. space program. This tower contained a cluster of rockets that would effectively pull the spacecraft off of - and away from - the rocket. While this was effective when the rocket was on the pad, and for the first part of the ascent, it becomes ineffective within a couple of minutes. The built in SuperDraco thrusters on the other hand remain operational, and are maintained throughout the flight. These are also the thrusters that will enable Dragon to "land propulsively on Earth or another planet with the precision of a helicopter".
