SpaceX prepares to test its next generation rocket engine

9:23 am

The competition heats up: SpaceX’s first Raptor rocket engine has now been built and has been shipped to the company’s test facility in Texas to begin testing.

The Raptor is SpaceX’s next generation of rocket engine. It may be as much as three times more powerful than the Merlin engines that power its Falcon 9 rocket and will also be used in the Falcon Heavy rocket that may fly in late 2016 or early 2017. The Raptor will power SpaceX’s next generation of rocket after the Falcon Heavy, the so-called Mars Colonial Transporter.

Although official details regarding the Raptor engine remain scarce, SpaceX founder Elon Musk has suggested the engine will have a thrust of about 500,000 pounds, roughly the same power as a space shuttle’s main engines. Whereas the shuttle was powered by three main engines and two booster rockets, however, it is believed the large rocket SpaceX uses to colonize Mars would likely be powered by a cluster of nine Raptor engines.

Like I said in my previous post, the rest of this decade should be very exciting in space, and that excitement will have be because of private enterprise and freedom, not NASA’s fake mission to Mars, with Orion.

SpaceX test fires one of its recovered first stages

8:16 am

The competition heats up: SpaceX has completed a full duration test firing of one of its recovered first stages.

The JCSAT-14 stage [which was the third recovered stage and the second to land on a barge] isn’t expected to fly again due to the initial evaluations into damage received via its high-velocity return. However, it will still provide useful test data. “Most recent rocket took max damage, due to very high entry velocity,” noted Elon Musk. “Will be our life leader for ground tests to confirm others are good.”

That testing on the JCSAT-14 booster began on Thursday, with the stage placed on the test stand at McGregor – ironically after the stand was vacated by the JCSAT-16 first stage – which recently completed testing and has since been shipped to Florida for its launch next month. The returned stage is also sported a new cap, which may be providing some simulated weight to aid the required data gathering during the test firing.

The booster conducted a long firing of 2 minutes 30 seconds (the duration of first stage flight), that began around 7pm local time on Thursday (per L2 McGregor), which will provide vital data on the returned stage as SpaceX continue preparations for validating one of its recovered booster for a re-launch later this year.

It is once again important to point out that SpaceX’s engineers here have an enormous advantage over every other rocket engineer who has ever lived. They have in hand a recovered first stage that was actually used to launch a satellite into orbit, giving them the ability to test it and find out precisely how such equipment fares during launch. This will give them the ability, unavailable to others, to make engineering improvements that will make future first stages even more reliable and reusable.

NASA guesses SpaceX’s Dragon-Mars mission will cost $300 million

6:20 pm

At a meeting of NASA’s Advisory Council yesterday a NASA official estimated that SpaceX will probably spend about $300 million on its Dragon mission to Mars.

Asked by the committee how much SpaceX was spending, Reuter indicated that the company’s investment was 10 times that of NASA. “They did talk to us about a 10-to-1 arrangement in terms of cost: theirs 10, ours 1,” he said. “I think that’s in the ballpark.” Given NASA’s investment, that implies SpaceX is spending around $300 million on Red Dragon.

SpaceX has not disclosed its estimated cost of the mission, or how it will pay for it. “I have no knowledge” of how the company is financing the mission, Reuter said when asked by the committee.

I suspect that the guess is significantly wrong. NASA is providing $32 million. SpaceX plans to charge customers $90 million for a single Falcon Heavy launch, which means its cost for that launch is likely half that, say $45 million. That adds up to $77 million. The cost for a Dragon capsule is not even close to $223 million, which is what remains if NASA’s guess is right, which based on this rough estimate I seriously doubt. I would bet that a single Dragon probably costs far less than $20 million. Remember, they are nothing more than basic manned capsules, and SpaceX is building enough of them to almost have an assembly line going.

So, let’s round up and say that the cost for the mission is really about $100 million (including NASA’s contribution). Other costs, such as the staff to run the mission for at least a year, will increase this cost, but not enough to bring the total to NASA’s guess of $300 million. I suspect that SpaceX will not spend anything close to $100 million of its own money for this Dragon mission to Mars.

All in all, this amount of investment seems reasonable, based on the scale of costs in the launch industry. And SpaceX’s willingness to invest some of its own money for this mission is probably wise. In publicity alone it is priceless.

New rocket company raising investment capital

4:44 pm

The competition heats up: Two former employees of SpaceX and Blue Origin have teamed up to start their own rocket company, aimed at using 3D printing technology to build rockets “with zero human labor.”

The funding rounds are described in two documents filed in May and this month with the Securities and Exchange Commission. The first filing reports that $1.1 million in equity was sold to investors. The second filing serves as a new notice of $8.4 million in equity sold, out of a $9.6 million offering.

The filings indicate that Relativity Space is based in Seattle, but in response to an email inquiry, the company declined to say anything further about its location, its business plan or its investors. “We are entirely in stealth mode and will comment more when we are ready,” the company said.

New companies come and go, but the fact that the guys in charge of this come from these two companies, and have already raised significant investment capital, suggests attention should be paid.

Reused Dragon cargo capsule to ISS within a year

4:05 pm

The competition heats up: SpaceX hopes to launch a previously flown Dragon capsule to ISS sometime with the next year.

This fall, SpaceX plans to refly one of its landed Falcon 9 rockets for the first time — and a Dragon capsule should make history by launching on a repeat ISS resupply mission shortly thereafter, a NASA official and a SpaceX representative said during a postlaunch news conference Monday. “I think we’re looking at SpaceX-11,” said Joel Montalbano, NASA’s deputy manager of ISS utilization, referring to the 11th resupply mission the company will fly with Dragon and the Falcon 9. (Monday’s launch kicked off SpaceX-9.)

I had been wondering when SpaceX would try to reuse a Dragon, and had assumed the reason it hadn’t happened yet was partly because of NASA reluctance combined with the delays connected with the launch failure last year. Either way, it appears that NASA is now on board and that the company is beginning to gear up for that first reflight.

SpaceX seeks two more pads for returning 1st stages

3:58 pm

The competition heats up: SpaceX is asking for permission to establish two more landing pads so that it will have the capability of landing three first stages all within minutes of each other.

“SpaceX expects to fly Falcon Heavy for the first time later this year,” the company said in a statement responding to questions. “We are also seeking regulatory approval to build two additional landing pads at Cape Canaveral Air Force Station. We hope to recover all three Falcon Heavy rockets, though initially we may attempt drone ship landings” at sea.

This news suggests two things: 1. The first Falcon Heavy launch is definitely coming soon. 2. They are going to try to return all three 1st stages during that first launch.

SpaceX chooses recovered first stage to reuse

4:31 pm

The competition heats up: SpaceX has chosen as the first Falcon 9 first stage to reuse the one that was the first to land successfully on a barge on April 8.

Though they have not announced the mission it will fly, I strongly suspect it will be one of the two SES communications satellites scheduled to launch in the fall. SES has already said they want to buy a launch using a re-used first stage, and the two SES satellites scheduled for the fall have some redundancy between them.

Iridium’s next generation constellation of satellites

9:10 am

The competition heats up: Iridium prepares the first 10 of a total of 81 new satellites for launch on SpaceX’s Falcon 9 in September.

The Iridium Next program is a $3 billion investment by Iridium, according to Matt Desch, Iridium’s chief executive officer. Iridium’s purchase of 81 satellites represents approximately $2.2 billion of that cost, Desch said, and the company’s launch contract with SpaceX for seven Falcon 9 flights was valued at $492 million when the parties signed it in 2010. That was the largest commercial launch contract in history until last year’s 21-launch order by satellite Internet provider OneWeb with Arianespace.

The first 10 Iridium Next satellites will fly on a Falcon 9 rocket in September, followed by a second launch as soon as December with the next batch. Iridium managers will give the go-ahead for the second launch once the first 10 satellites finish initial in-orbit tests, Desch said. The other five launches should occur about once every two months next year to fill out the Iridium Next fleet 485 miles (780 kilometers) above Earth. Iridium’s contract with SpaceX calls for all the missions to fly on newly-built Falcon 9s, a situation unlikely to change any time soon since insurance arrangements for the initial launches have been finalized.

But Desch said he is open to purchasing reused Falcon 9 boosters in the future “if they’re the right price.”

To meet this schedule SpaceX’s launch schedule will have to ramp up considerably from its present rate of one launch about every three weeks.
