FCC approves SpaceX’s Starlink constellation

9:17 am

Capitalism in space: The FCC has approved SpaceX’s revised plan for its Starlink satellite constellation designed to provide global internet access.

SpaceX already had authorization for 4,425 Starlink satellites that would use Ku- and Ka-band radio spectrum to beam internet data, but last November, the company asked the FCC to sign off on a plan that would put more than a third of the satellites in 550-kilometer-high (340-mile-high) orbits rather than the previously approved 1,150-kilometer (715-mile) orbits.

Eventually, SpaceX plans to add another wave of more than 7,500 satellites in even lower orbits to enhance the constellation’s coverage.

They hope to begin launching their first set of satellites by May, and begin commercial operations as early as 2021.

NASA safety panel on SLS schedule, Dragon explosion

9:08 am

NASA’s safety panel held a long scheduled meeting to review NASA’s on-going manned projects, and had the following to say:

The first story describes very little new information about the explosion on April 20th that destroyed the Dragon crew capsule during engine tests, other than it occurred in connection with the firing of the Dragon’s eight SuperDraco engines. I am being vague because they were.

The second story describes the panel’s strong objection to any effort by NASA to trim the test program for SLS in order to meet the Trump administration’s 2024 deadline for returning to the Moon. It also confirms officially for the first time that NASA will not be able to fly the first unmanned mission of SLS in 2020. That flight is now expected in 2021, a decade after NASA began development of SLS, and seventeen years after George Bush Jr first proposed NASA build this heavy-lift rocket.

That’s practically one person’s entire career at NASA. Seems pretty shameful to me.

While I actually agree with the panel’s advice in both of these stories, both stories however do reflect the overall culture of this safety panel: Go slow, take no risks, be patient. This culture is in fact so cautious that it has served to practically make impossible any American exploration of space, on our own rockets.

Based on what I expect now during the investigation of the Dragon explosion, I would not be surprised if the panel successfully delays the first manned Dragon launch another year or two or three.

Starliner does first splashdown recovery tests

9:18 am

Capitalism in space: Though Boeing intends to bring its manned Starliner capsule down on land, it has begun water recovery tests of the capsule, working in conjunction with Air Force recovery teams, to prepare for the possibility that it might sometimes have to splashdown in the ocean.

While the article reviews the tests, it also contains this interesting piece of information:

While today’s test was the first in-water practice run for Starliner at sea rescue, it represents a much larger DoD commitment to space crew rescue operations – universal procedures that would be followed for Starliner, Dragon, and Orion.

During ascent for Starliner, Dragon, and Orion, the 304th Rescue Squadron will have two teams stationed along the east coast of the United States, one at Patrick Air Force Base (just South of the Cape) and the other in Charleston, South Carolina.

The Patrick team, Rescue 1, will be responsible for on-pad aborts that place a capsule in the water or for aborts in the first couple minutes of flight that place the capsule within a 200 nautical mile zone from the Cape.

After that distance is exceeded, the Charleston crew (Rescue 2) would be responsible for rescue of a launch-aborting crew vehicle anywhere else across the Atlantic.

The third team, stationed in Hawai’i, (also part of Rescue 2) would be responsible for any after-launch immediate landing need or off-nominal Station return contingency that places a Starliner or Dragon in the Pacific.

It appears that the responsibility for water recovery of American manned spacecraft has been taken over by the Air Force. Up until now SpaceX has performed its own water recovery for its unmanned cargo Dragon capsules.

Dragon capsule suffers problem during engine test

9:20 pm

Bad news: A SpaceX man-rated Dragon capsule suffered an “anomaly” during an engine test today.

“Earlier today, SpaceX conducted a series of engine tests on a Crew Dragon test vehicle on our test stand at Landing Zone 1 in Cape Canaveral, Florida,” a company spokesperson told Space.com in a statement. “The initial tests completed successfully but the final test resulted in an anomaly on the test stand.”

At the moment we do not have much information. We do not know if this capsule was the one that flew in March and was going to be used in the launch abort test prior to the manned mission, or whether it was another capsule planned for the manned mission itself.

Nor do we know what the problem was, or if it was a SuperDraco thruster that failed.

Regardless, this is going to cause a significant delay in SpaceX’s flight schedule. While they might be able to complete an investigation and resume flying within months, NASA will insist on a NASA-type investigation, drawn out for far longer, possibly years.

SpaceX booster damaged on barge but not lost

6:01 am

According to an Associated Press report today, the Falcon Heavy core stage was damaged when it toppled over in heavy seas, but was not entirely lost.

The company confirmed Tuesday that the unsecured core booster toppled onto the platform over the weekend, as waves reached 8 to 10 feet. SpaceX chief Elon Musk says the engines seem OK. There’s no immediate word on how many of the booster pieces remain on board.

Musk says custom devices to secure the booster weren’t ready in time for this second flight of the Falcon Heavy.

From this report it sounds like the engine part of the stage remained on the barge. We shall see. Also, this report might explain the lack of a robot to secure the stage. The robot wasn’t ready, but rather than delay the launch for this reason they went ahead.

SpaceX loses Falcon Heavy core stage in rough seas

6:05 am

SpaceX announced today that it lost the Falcon Heavy core stage in rough seas on its way back to port.

“Over the weekend, due to rough sea conditions, SpaceX’s recovery team was unable to secure the center core booster for its return trip to Port Canaveral,” SpaceX spokesman James Gleeson told FLORIDA TODAY. “As conditions worsened with eight- to ten-foot swells, the booster began to shift and ultimately was unable to remain upright.” “While we had hoped to bring the booster back intact, the safety of our team always takes precedence. We do not expect future missions to be impacted,” he said.

While SpaceX does have hardware on its drone ship designed to secure first stages – often referred to as a flat “robot” that holds them in place – it was not used for this mission, which successfully took an Arabsat satellite to orbit last Thursday. The connections between the robot and center core aren’t compatible like they would be with a standard Falcon 9 booster, but SpaceX is expected to upgrade both in the future.

This is unfortunate. At the same time, it illustrates how far ahead of its competitors SpaceX is. While others throw their first stages away, SpaceX is disappointed when it loses one.

SpaceX recovers Falcon Heavy fairings and will reuse them

9:39 pm

Capitalism in space: In a tweet yesterday Elon Musk said that SpaceX had recovered both fairings from the Falcon Heavy launch and plans to reuse them later this year.

It seems that what the company has found is that catching the fairings is not necessary. Providing them parachutes and a guidance system so they land gently with the open half up, so they float literally like a boat, prevents any serious damage. The guidance system also gets them to land close enough for a quick pickup at sea.

Based on this knowledge, recovering and reusing these fairings was probably always a simple and fairly easy thing to do. No one however had had the smarts or open-mindedness to think of doing it. Moreover, from the article:

Musk told reporters last year that the fairing costs around $6 million. He said the first stage of the Falcon 9 rocket comprises about 60 percent of the cost of a launch, with the upper stage responsible for 20 percent, and the fairing another 10 percent. The remaining 10 percent of the cost of a Falcon 9 mission come from charges stemming from launch operations, propellant and other processing expenses, Musk said last year.

In other words, by recovering both the first stage and the fairings, SpaceX makes their rockets about 70 percent reusable. That’s actually more reusable than the space shuttle ever was.

I must add that the section of the shuttle that was the most reusable was the section of SpaceX’s rockets that they as yet are not reusing, the upper stage. In other words, we have now tested and proven the technology for making an entire orbital rocket reusable, just never in the same vehicle. SpaceX is taking advantage of this knowledge and clearly applying it to their Super Heavy/Starship next generation rocket, which also means the likelihood of getting that to work is actually quite high and not as radical as many think.

The Falcon Heavy reported by modern shoddy journalism

12:00 pm

Yesterday’s magnificent successful launch of SpaceX’s Falcon Heavy rocket elicited numerous news stories from the general press, most of which were reasonably accurate if very superficial in their coverage. As a space guy who focuses on this stuff, I find that much of the reporting in the mainstream press reads as if the author has just discovered the subject, and is scrambling to come up to speed quickly.

This CNN article is typical. The journalist gets most of her facts right, but her lack of context because she hasn’t been following the subject closely causes her to not understand the reasons why the Falcon Heavy will fly less than the Falcon 9.

Falcon Heavy is not expected to fly nearly as often as its smaller counterpart, which has completed more than 20 missions since last February. Falcon Heavy only has five missions on its manifest so far.

The basic facts in this quote are entirely true, but it somehow implies that the Falcon Heavy is simply not that much in demand, which isn’t true. The reason Falcon Heavy has approximately one quarter of the missions of the Falcon 9 is because it is still new and it hasn’t yet garnered the customers. Also, as a slightly more expensive rocket than the Falcon 9 ($90 million per launch vs $60 million) fewer customers are going to buy it.

Still, the Falcon Heavy has more than five missions upcoming, with contracts for at least seven launches, by my count, and having this many contracts this quickly is remarkable, considering the rocket’s newness. It is more than the Russians are getting for their Proton rocket, around since the 1960s. And it is almost as many contracts as both Arianespace and ULA are each getting on a yearly basis.

Falcon Heavy is clearly becoming a big financial success, and will in the next few years I think routinely fly three to four times per year. There is a lot of demand for it, which will only grow with time.

This flaw in getting the background right by the CNN reporter is not really a big deal, but it does illustrate why it is better for ordinary citizens to get their news not from generalists in the mainstream press but from specialists in each field (such as myself), who understand the details more closely and can get the context right.

However, every once in awhile the mainstream press publishes a story that is so egregious and badly written that I think it necessary to give it a public pan, if only to make others aware of that this kind of bad journalism is not unusual. I also admit that it can be quite entertaining to highlight this pitifully bad journalism.

Yesterday one of Houston’s local television stations, KPRC-TV, published its own quick report on the Falcon Heavy launch. And boy, was that report a facepalm.

SpaceX gets NASA launch contract

8:55 am

Capitalism in space: One week after dropping its protest for losing the bidding competition for the Lucy asteroid mission, SpaceX has been awarded by NASA the launch contract for its Double Asteroid Redirection Test (DART) mission, set for launch in June 2021.

The $61 million launch price is significantly lower than past NASA contracts for Falcon 9 launches. NASA awarded SpaceX a contract for the Sentinel-6A satellite in October 2017 for a November 2020 launch on a Falcon 9 from Vandenberg at a total cost of $97 million. The Surface Water and Ocean Topography (SWOT) satellite will launch on a Falcon 9 in April 2021 under a contract awarded in November 2016 at a value of $112 million.

This low cost technology test mission, costing a total of $9 million, was initially going to be launch as a secondary payload. That NASA is now going to pay SpaceX for a full launch is most intriguing. It seems to me that there might be a bit of quid pro quo here. NASA wanted that protest dropped, and offered this launch to convince SpaceX to do that, as long as the launch cost was kept low. $60 million is really SpaceX’s standard price for Falcon 9 launch, using new boosters, but for NASA that is the least they’ve paid. How much more this is than what NASA would have paid to launch DART as a secondary payload is the real question.

The second Falcon Heavy launch

3:10 pm

I have embedded the live stream of Falcon Heavy launch below the fold. It does not go live until just before launch, which is now scheduled for 6;35 pm (Eastern).

The live stream is now live. I will post updates below, so refresh your screen to see them.

This is not a routine SpaceX launch, where we have become nonchalant about the company’s ability to vertically land a first stage. They admit getting the core stage back will be challenging. They also admit that this is essentially a countdown of three rockets, so they are going to be very conservative. If anything pops up during countdown, they will scrub and try another day.

They have launched.

The side boosters have successfully separated.

The center core stage has successfully separated.

Re-entry burns for the two side boosters has been completed.

Falcon Heavy core stage on drone ship

Re-entry burn on the core stage has been completed.

Both side boosters have landed.

The payload is in orbit.

The core stage has landed successfully on the drone ship.

Though the satellite has not yet been deployed, the rest of this mission is almost certainly going to go as planned, as it is essentially identical to a normal Falcon 9 launch. Update: payload successfully deployed!

Getting all three stages back is a notable achievement. They intend to recycle the two side cores and use them on the very next Falcon Heavy launch in June. The core stage will likely be reused as well but when has not yet been announced.

The leaders in the 2019 launch race:

4 SpaceX
4 China
4 Europe
3 Russia

The U.S. leads the pack 7 to 4 in the national rankings.

In the heavy lift launch race, SpaceX is by far in the lead in successful launches:

2 SpaceX
1 China
0 SLS (NASA)

I should add that I am being generous to include China’s Long March 5 in this heavy lift list. It really doesn’t qualify, but it remains the only other near competitor.

Falcon Heavy launch now set for tomorrow evening, April 10

8:43 am

Capitalism in space: SpaceX’s second launch of its Falcon Heavy rocket, the world’s most powerful, has now been rescheduled for 6:36 pm (eastern) on April 10.

This will definitely be worth watching. (I will post the SpaceX live stream link when it goes up.) If all goes well, the three first stage boosters will all land themselves after first stage separation, with two coming in simultaneously on neighboring landing pads in Florida, with the third landing very shortly thereafter on its landing barge in the Atlantic.

A success here will also give the Falcon Heavy two successful launches, two more than SLS (with none), and one more than China’s Long March 5, which is half as powerful but has not launched in almost two years after it failed on its second launch attempt.

The comparison with SLS is more pertinent. Tomorrow’s launch, if successful, will once again demonstrate the complete failure of NASA’s SLS rocket. This government boondoggle has been in development since 2004 in various iterations, for a cost that is likely to exceed $25 billion, fifty times more than it cost SpaceX to develop and make operational the Falcon Heavy. SLS’s first launch, originally scheduled for 2017, is now set to launch in June 2020, but is also more likely to be delayed months, if not more. Beyond that it will likely be more years before its second launch.

Falcon Heavy meanwhile is scheduled to do its third launch in mere months, should tomorrow go off without a hitch. It also has contracts for at least seven future launches. Nor would I be surprised if it completes most of these launches before SLS flies for the first time.

At some point the dimwits in Washington will I hope finally notice the contrast, and stop wasting money on SLS. Give it time, however. They are not very smart, and aren’t really interested in the needs of the American nation.

SpaceX drops protest against NASA launch decision

10:54 am

SpaceX has decided to withdraw its protest against NASA’s decision to choose ULA as the launch vehicle for its Lucy asteroid mission.

The company did not provide any reason for the withdrawal. I suspect Musk decided that it was doing SpaceX harm both publicly and privately. Publicly it threatened the launch date of Lucy, which might cause a significant and fatal delay to the mission. That did not make SpaceX look good to the general public.

Privately, I suspect that the protest was hurting SpaceX with NASA officials. They almost certainly did not say so directly, but I am certain they were able to make this clear in any number of ways. This, combined with the agency’s new willingness to consider commercial rockets, like the Falcon Heavy, for its lunar plans, probably convinced SpaceX that it was doing itself more harm than good with the protest.

Falcon Heavy dress rehearsal countdown and static fire today

8:14 am

Capitalism in space: SpaceX hopes to complete today its standard prelaunch dress rehearsal countdown for the second Falcon Heavy launch, now likely scheduled for April 9.

The launch had previously been set for April 7.

The article provides a nice overview of the Falcon Heavy. It also included this tidbit:

Unlike most past missions, the two side boosters are already booked for a second launch. They – in addition to the brand new center core B1057 – will help launch the Air Force’s STP-2 mission, currently No Earlier Than (NET) June.

That they have already scheduled reuse of the side boosters for the next Falcon Heavy launch indicates just how confident they have become about recovering those boosters.

UPDATE: Dress rehearsal countdown and static fire have been completed. According to an Elon Musk tweet, the data looks good, but he cautioned that as this will be the first Falcon Heavy launch using Block 5 boosters, the launch date might change as they review the data.

NASA head says that Falcon Heavy remains a future option for Orion

4:56 pm

At an agency meeting for employees NASA administrator Jim Bridenstine reiterated that NASA is still seriously considering the use of SpaceX’s Falcon Heavy for future Orion lunar missions instead of SLS.

Bridenstine then laid out one scenario that has huge implications, not for a 2020 launch, but one later on. Until now, it was thought that only NASA’s Space Launch System could directly inject the Orion spacecraft into a lunar orbit, which made it the preferred option for getting astronauts to the Moon for any potential landing by 2024. However, Bridenstine said there was another option: a Falcon Heavy rocket with an Interim Cryogenic Propulsion Stage built by United Launch Alliance. “Talk about strange bedfellows,” he mused about the two rocket rivals.

This plan has the ability to put humans on the Moon by 2024, Bridenstine said. He then emphasized—twice—that NASA’s chief of human spaceflight, William Gerstenmaier, has yet to bless this approach due to a number of technical details. His reservations include the challenge of integrating the Falcon Heavy rocket in a horizontal position and then loading Orion with fuel in a vertical configuration on the launchpad. The Falcon Heavy would also require a larger payload fairing than it normally flies with. This would place uncertain stress on the rocket’s side-mounted boosters.

All the problems outlined in the second paragraph are the result of bad past management at NASA. Just as you design your rocket based the rocket engines you have — in order to save time and money — you design your capsule and manned vehicles based on the rockets that are available. NASA did not do this. It built Orion in a fantasy la-la land, without addressing the real world rocket options available. Now it has to either reconfigure, or get SpaceX to rethink the Falcon Heavy. Neither option will be cheap.

Regardless, Bridenstine’s statement is another shot across the bow to the porkmeisters in Congress. SLS is on shaky financial ground. It cannot compete in price with the commercial options. More significantly, it cannot come close to matching the launch rates of the private rockets. In the time NASA could put together one SLS launch, SpaceX could likely fly five to ten Falcon Heavies, and still do it for less money overall.

SLS is now tasked with a December 2020 deadline for launching that first unmanned test flight. Should it fail to meet that date, the political battle lines are now being laid for replacing it.

Update on the upcoming second Falcon Heavy launch

8:58 am

Link here. The rocket’s three first stages will be Block 5 versions. A static fire dress rehearsal countdown is set for April 1, with the launch scheduled for April 7.

Though the article does not say so, it hints at a number of serious engineering issues discovered during the first Falcon Heavy launch, suggesting to me once again that the success of that launch was somewhat fortuitous. SpaceX has spent the last year correcting those issues in preparation for this launch. Based on the company’s track record, the odds are very high the April 7 launch will be successful.

Russia cuts Proton price to match SpaceX

9:00 am

Capitalism in space: Dmitry Rogozin, the head of Roscosmos, yesterday said that Russia will cut costs so that the price they charge for a Proton launch will match SpaceX.

Russia is struggling to regain its Proton customer base after the launch failures of the past few years. I don’t think matching SpaceX’s prices will do it. Right now satellite companies view them as offering a less reliable product, and until they can prove this impression false they need to offer their rocket for even less that SpaceX.

This is in fact what SpaceX did at the beginning. Its rockets were untested and thus risky to use. To compensate they offered a cheaper way to space. Now Russia has to do the same, or the business will continue to go to others. I wonder if Rogozin understands this.

Update of Starhopper testing in Texas

8:43 am

Link here. Nothing spectacular yet, just steady and relatively quick developments.

I did find one aspect of these events a little disturbing:

In quick order, residents of Boca Chica Village were notified via mail of imminent tests and road closures that would occur as early as this week, the week of 18 March.

The notice to residents revealed that a security checkpoint would be set up on the road leading to Boca Chica Village and that residents would have to show proof of residence in order to gain access to their homes; any passengers in those vehicles would also have to show proof of residence.

This indicates that no guests will be allowed past the security checkpoint during the coming flight test operations of Starhopper.

A hard checkpoint beyond which no access to Boca Chica Beach will be granted will be further down the road.

By what right do the authorities have the power to prevent American citizens from bringing guests to their homes? None. If I lived in this development I would fight this, hard.

Air Force’s launch contracting plans under scrutiny

9:58 am

It appears the Air Force wants to decide now which two rocket companies it will use for its launch needs in the 2022 to 2026 time period, and this desire is raising hackles among those companies.

[T]he Air Force will choose only two companies to meet its launch needs from 2022 to 2026, with one provider winning 60 percent of the contracts and the other taking 40 percent. There is no provision to on-ramp other companies during the time frame.

This sets up a rather frantic competition between the incumbents, ULA and SpaceX, and newcomers Blue Origin (with its New Glenn booster) and Northrop Grumman (with its Omega rocket). Moreover, the timing appears to prejudice the competition in favor of the incumbents, which already have existing launch systems the government can assess.

Something is really fishy here. Why does the Air Force need to limit its services to only two companies? And why do they have to make this decision now, three to seven years before the launches will occur? Common sense says you instead issue specific contract bids, for each launch, as they are needed, thus allowing as many companies as possible to compete for the business.

In fact, this policy seems to directly contradict the Air Force’s stated goal, repeated many times in the past few years, to widen competition in the launch industry, both to lower cost and to give the military strategic redundancy in its needed launch services.

First SpaceX Starship Hopper tests this week?

8:44 am

Capitalism in space: According to this news story on Sunday, SpaceX could attempt its first Starship Hopper tests this week.

A sheriff hand-delivered road closure notices to residents on Friday, according to a local resident. The document warned locals that SpaceX will “conduct testing” as soon as Monday, March 18.

The article also cites a flurry of tweets about the hopper that Elon Musk made on Sunday. Unfortunately, Musk’s tweets do not say anything about tests this week.

Regardless, it appears that SpaceX might actually be close to beating the schedule it announced for these tests back in November, when Musk said they were aiming for tests in June. If so, this would be a remarkable achievement, one that is almost unheard of in the aerospace launch industry.

SpaceX about to install engines on Starship hopper

9:26 am

Capitalism in space: Late last week SpaceX officials revealed that they are about to install the first two Raptor engines on their Starship hopper prototype being assembled at the Texas spaceport.

According to an official SpaceX statement, once Raptor is installed on Starhopper, the integrated vehicle will perform a combination of ground systems testing, propellant loading, static fire tests, and low-altitude hover demonstrations to prove out the brand new vehicle, engine, and facilities. Prior to the final months of 2018, the build site, launch pad, and prototype Starship now preparing for imminent hop tests were little more than empty dirt lots on the southern tip of the Texas coast.

…“SpaceX will conduct checkouts of the newly installed ground systems and perform a short static fire test in the days ahead,” he said. “Although the prototype is designed to perform sub-orbital flights, or hops, powered by the SpaceX Raptor engine, the vehicle will be tethered during initial testing and hops will not be visible from offsite. SpaceX will establish a safety zone perimeter in coordination with local enforcement and signage will be in place to alert the community prior to the testing.” – James Gleeson, March 8th, SpaceX

It is not clear when these first hopper tests will occur, but based on the pace that SpaceX is setting, it should not be too far into the future. Before that however they will likely need to first do some static fire tests, on the ground.

Dragon successfully splashes down in Atlantic

8:58 am

Capitalism in space: SpaceX’s manned Dragon capsule has successfully returned to Earth, splashing down in the Atlantic this morning.

There is a short video at the link showing the splashdown.

As far as I can tell, this test mission went 100% right. They now have the capsule they will use for the launch abort flight, which they hope to do by June, if not sooner. Assuming that goes well, they will be ready to do the manned flight by July, as planned.

The only thing I can see preventing this would be elements in NASA’s bureaucracy, Congress, and the federal government that are hostile to SpaceX and the concept of independent free Americans doing great things. These elements prefer giving power and control to their big bloated government, even if it can’t accomplish anything and that failure gives aide and comfort to hostile foreign powers.

We shall see if those elements move to block this mission in the coming months.

Air Force awards ULA and SpaceX three launch contracts each

1:20 pm

Capitalism in space: The Air Force this week released more details about the new launch contracts for both ULA and SpaceX worth just under three quarters of a billion dollars.

The contracts announced in February by the Air Force’s Space and Missile Systems Center were split between ULA and SpaceX, rivals in the U.S. launch industry. ULA won deals for up to three launches worth $441.76 million, and the Air Force awarded SpaceX contracts worth $297 million, also for three missions.

I had reported this back in February when it was first announced, but it was not then revealed that one of the SpaceX launches would be with the Falcon Heavy, the second such Air Force launch planned. That the Air Force awarded this contract prior to its first launch, now scheduled for no earlier than June 2019, is somewhat surprising. I would have expected them to wait to first see if that launch, only the second Falcon Heavy launch, was successful.

The article also notes a minor change by the Air Force in its launch program.

The Air Force has also given a new name to the Evolved Expendable Launch Vehicle program, a multibillion initiative begun in the 1990s to fund and oversee the development and operations of the Atlas 5 and Delta 4 rockets now owned by ULA.

The Space and Missile Systems Center announced March 1 that the EELV program’s new name is the National Security Space Launch program, in response to language in the 2019 National Defense Authorization Act.

They really needed to eliminate “Expendable” from the name, since the first stage of SpaceX’s rockets are not expendable, and it is expected that future rockets will be reusable as well. Moreover, EELV was created in the 1990s to create a launch monopoly for Boeing and Lockheed Martin, which then merged to create ULA. That monopoly no longer exists, and the military is now aiming to widen the competition, opening it up to more companies.

Increased isopropyl alcohol detected at ISS following Dragon docking

8:46 am

The Russian press today announced that there was a significant increase in the amount of isopropyl alcohol detected in the atmosphere of ISS following docking and opening of the hatch of SpaceX’s Dragon capsule.

While obviously this needs to be investigated, there are several details the Russian press leaves out. First, what normally happens when a manned capsule or new module arrives and the hatch opens? I suspect we always see a jump in readings for a wide range of atmospheric components. Second, what harm does this increase in ispropyl alcohol have to the station, its experiments, or its occupants? I suspect none, though obviously if it could be avoided that would be better.

Once again, we need to be aware that the Russians motives here might not be entirely pure. They have political and economic reasons to work against a success by SpaceX, and articles such as this reflect that. Issues like this of course need to be checked out and fixed if possible or necessary, but the goal of this article might not be that at all.

Dragon successfully docks with ISS

8:58 am

Capitalism in space: SpaceX’s Dragon capsule, designed to carry humans to space, has successfully docked for the first time at ISS.

The flight really has only one major task left, which it to return safely to Earth, which presently is scheduled for 8:45 am (eastern) on March 7. I expect that to go smoothly as well.

NASA and SpaceX will of course need to review all the test data from this unmanned test flight before okaying a manned flight. SpaceX also needs to first do a launch abort test, using this capsule. However, I do not expect either to result in any issues that should prevent a manned launch in July, as SpaceX presently plans.

NASA however might think differently. There have been strong factions within its management and bureaucracy that are hostile to this effort, and have been working to stall or stop it.

Europe to build reusable first stage

10:15 am

Capitalism in space: Even as Europe works to develop Ariane 6, their non-reusable next generation rocket, Ariane Group and the French are now considering replacing it with a different rocket with a reusable first stage.

Late last week, the European rocket maker Ariane Group and the French space agency CNES announced the creation of an “acceleration platform” to speed development of future launch vehicles. The initiative, called ArianeWorks, would be a place where “teams work together in a highly flexible environment, open to new players and internationally.”

“In this era of NewSpace and in the context of fierce competition, ArianeWorks will accelerate innovation at grassroots level, in favor of mid-tier firms and start-ups, with commitment to reducing costs a major priority,” a news release sent to Ars states.

As part of the announcement, the organizations released a promotional video for the group’s first step—a so-called Themis demonstrator. The goal of this project is to build a multiple-engine first-stage rocket that launches vertically and lands near the launch site. The rocket will be powered by Europe’s Prometheus engine, a reusable liquid oxygen and methane engine that may cost as little as $1 million to build.

Essentially they are copying SpaceX’s Falcon 9 rocket, except for the fuel. And they admit it. Moreover, this action tells us that the problems Ariane 6 has had getting European contracts has become serious enough that they have finally recognized that it simply cannot compete with the new wave of reusable rockets expected in the next decade. Building a new rocket that does not have a reusable capability is not viable in the coming market.

They should have recognized this four years ago, but better late then never.

SpaceX first stage for launch abort returns to port

Capitalism in space: The first stage that SpaceX used (for the third time) last week to put three payloads into orbit, including Israel’s privately built lunar lander Beresheet, has returned to port and begun its preparation for its fourth launch, the launch abort test required before the company can fly humans on its Dragon manned capsule.

Musk tweeted that the launch escape test could occur in April. Hans Koenigsmann, SpaceX vice president of build and flight reliability, said Friday that teams are looking at whether the in-flight abort could be moved forward from June.

SpaceX plans to reuse the Crew Dragon spacecraft slated to fly to the space station this weekend for the in-flight abort. Assuming a March 2 launch, the capsule is scheduled to splash down in the Atlantic Ocean on March 8, where teams will retrieve the spacecraft and bring it back to Cape Canaveral for the abort test.

The timing of the in-flight abort test “depends on when Crew Dragon comes back,” Musk tweeted. “That’s scheduled for launch next Saturday, but (there’s a) lot of new hardware, so time error bars are big.”

Officials do not expect the Falcon 9 booster to survive the abort test, likely ending its lifetime at four launches, and three intact landings. “High probability of this particular rocket getting destroyed by Dragon supersonic abort test,” Musk tweeted. [emphasis mine]

Unless something significant goes wrong during next week’s unmanned Dragon test flight, the only thing that I see preventing a June or earlier launch abort test would be the paperwork NASA demands SpaceX fill out in order for the agency to rubberstamp the flight.

NASA okays March 2, 2019 Dragon test flight

4:11 pm

NASA has finally approved SpaceX’s unmanned test flight on March 2nd of its Dragon capsule.

They completed the last flight readiness review today, and the press conference revealing this decision is going on right now, at the link. They have noted one issue that came from the review today, relating to questions by the Russians about the software used by Dragon as it docks at ISS. It apparently they did not consider this a reason to delay the launch. They must think they can get it dealt with before the docking. (The manned Dragon docks itself directly with the station, rather than being berthed to the station by the robot arm, as is done with the unmanned cargo Dragon capsule.)
