Update on SpaceX’s plans for Starship

According to FAA regulatory documents, SpaceX has updated its development plan for Starship, including changes in its overall plans for its Boca Chica facility.

The document also lays out a three-phase test program, which it says “would last around 2 to 3 years”:

Phase 1: Tests of ground systems and fueling, a handful of rocket engine test-firings, and several “small hops” of a few centimeters off the ground. The document also includes graphic layouts, like the one above, showing the placement of water tanks, liquid methane and oxygen storage tanks (Starship’s fuels), and other launch pad infrastructure.

Phase 2: Several more “small hops” of Starship, though up to 492 feet (150 meters) in altitude, and later “medium hops” to about 1.9 miles (3 kilometers). Construction of a “Phase 2 Pad” for Starship, shown below, is also described.

Phase 3: A few “large hops” that take Starship up to 62 miles (100 kilometers) above Earth — the unofficial edge of space — with high-altitude “flips,” reentries, and landings.

The first phase is now complete, with the company shifting into Phase 2.

Boca Chica meanwhile is no longer being considered a spaceport facility. Instead, its focus will now be a development site for building Starship and Super Heavy.

Results released of July Vega launch failure investigation

The European Space Agency (ESA) this week released the results of its investigation into the July 10, 2019 launch failure of Arianespace’s Vega rocket, the first such failure after 14 successful launches.

The failure had occurred about the time the first stage had separated and the second stage Z23 rocket motor was to ignite. The investigation has found that the separation and second stage ignition both took place as planned, followed by “a sudden and violent event” fourteen seconds later, which caused the rocket to break up.

They now have pinned that event to “a thermo-structural failure in the forward dome area of the Z23 motor.”

The report says they plan to complete corrective actions and resume launches by the first quarter of 2020.

Charles Walker: the first commercial astronaut

Charles Walker on the Space Shuttle in November 1985

Last night I attended another one of the monthly Arizona Space Business Roundtable events held here in Tucson to bring together the business-oriented space community of this city.

The speaker was Charles Walker, who had flown three shuttle missions in 1984 and 1985, but not as a NASA-employed astronaut but as an employee of McDonnell-Douglas, making him the first astronaut to fly in space under the employ of a private commercial company.

Walker’s job then was to monitor and maintain a drug-processing unit designed to produce large quantities of pure biological hormones that on Earth were simply not possible. Gravity polluted the process, while weightlessness acted to purify things. If successful the hormone produced could be sold to fight anemia, especially in individuals taking radiation treatments. The image on the right shows him on his third and last shuttle mission, launched November 26, 1985. He is working with a handheld protein crystal growth experiment, with the larger hormone purifying experiment on the wall behind this.

According to Walker’s presentation yesterday, this third flight in November 1985 demonstrated the process worked and could produce as much as one liter of hormone, enough to easily make back the cost of the project and leave room for an acceptable profit. They were thus ready for fullscale production on future shuttle flights, only to have the entire project die when the Challenger shuttle was lost on January 28, 1986. With that failure President Reagan declared that the shuttle would no longer be used for commercial flights.

Their business plan had been dependent on the artificially low launch prices NASA had been charging them for shuttle flights. Without the shuttle there was then no affordable alternative for getting into orbit.

The process is still viable, and the need for these drugs still exists. Whether they could now be flown on the new cheaper private rockets, on board future private space stations like Bigelow’s B330, remains unknown. A new company would have to pick up the pieces, as McDonnell-Douglas no longer exists, having been absorbed into Boeing.

I personally suspect there is real money to be made here, should someone decide to go for it.

What struck me most while watching Walker speak was the same thing that has struck me whenever I have seen or interviewed any astronaut: He appeared to be such an ordinary down-to-earth human being. He could have been anyone you meet anywhere.

What made him stand out, as he described his upbringing and how he became an astronaut, was not his intelligence or any physical attribute, but his clear willingness to stay focused on his goals, to work has hard as possible to make them come true. What made him succeed was an unwavering commitment. He wanted to get to space, and by gum he was going to do it!

Charles Walker on first flight, August 1984
Walker on his first flight in 1984.

For example, he was too young to fly in the initial space race in the 1960s. When he finally was old enough and ready in the 1970s, NASA’s space program was being shut down. That option seemed dead. So instead, he began looking for another route into space, and found it with private industry and possibility of making money by using weightlessness to produce medicines in space that could not be produced on Earth.

Obviously, luck is always a factor. Had his project been a little delayed, only a year, it would have never flown, and he would never have gone into space. Similarly, he needed to be in the right place at the right time to get this particularly job in the first place.

At the same time, “Luck is a residue of design,” as said by Branch Rickey, general manager of the Brooklyn Dodges in the 1950s. Walker didn’t give up when the Apollo program died in the 1970s, and thus he put himself in the right place at McDonnell-Douglas when this opportunity arose.

We should all pay close attention. If you have a dream, you need to follow it, with a fearless wholehearted commitment. If you do, you still might not get it as you dreamed, but you will increase your chances, and regardless, you will end up doing far better for yourself and everyone around you.

And you still might end up like Walker, bouncing around in weightlessness out in the vast reaches of outer space.

Lunar lander company PTScientists purchased

Capitalism in space: The private commercial lunar lander company PTScientists has been purchased by an unknown investor, thereby avoid liquidation after declaring bankruptcy in July.

Berlin-based PTScientists and the law firm Görg, which handled the company’s bankruptcy administration, announced the acquisition in a German-language statement published Sept. 2. The announcement said neither the company buying PTScientists nor the purchase price would be disclosed, but that the deal was effective Sept. 1.

The acquisition, the announcement stated, allows PTScientists to retain its staff of about 60 people who had been working on lunar lander concepts, including a study for the European Space Agency of a mission to send a lander to the moon to perform experiments for in-situ resource utilization. ESA awarded that study to a team that included PTScientists as well as launch vehicle company ArianeGroup in January.

It seems that someone decided that this company was worth saving, and that it (and the private construction of private planetary missions) has the potential to make them money in time.

Vikram completes first de-orbit burn

The new colonial movement: India’s Vikram lunar lander has successfully completed its first de-orbit engine burn, lasting 4 seconds, adjusting its orbit slightly in preparation for landing on the Moon on September 7.

They will do a second burn tomorrow, further adjusting the orbit.

Note that the update says that this burn was by Chandrayaan-2, but this must be a mistake. The Vikram lander separated from the Chandrayaan-2 orbiter yesterday, and it is Vikram that is doing the orbital changes and will land on the Moon.

SpaceX declines to shift Starlink satellite to avoid collision

When European Space Agency (ESA) engineers realized there was a greater than normal chance that a new SpaceX Starlink satellite could collide with ESA’s already orbiting Aeolus satellite, they asked SpaceX to shift its orbit, only to have SpaceX decline.

According to Holger Krag, head of the Space Debris Office at ESA, the risk of collision between the two satellites was 1 in 1,000 – ten times higher than the threshold that requires a collision avoidance maneuver. However, despite Aeolus occupying this region of space nine months before Starlink 44, SpaceX declined to move their satellite after the two were alerted to the impact risk by the U.S. military, who monitor space traffic. “Based on this we informed SpaceX, who replied and said that they do not plan to take action,” says Krag, who said SpaceX informed them via email – the first contact that had been made with SpaceX, despite repeated attempts by Krag and his team to get in touch since Starlink launched. “It was at least clear who had to react. So we decided to react because the collision was close to 1 in 1,000, which was ten times higher than our threshold.”

As to why SpaceX refused to move their satellite, that is not entirely clear (the company did not respond to a request for comment). Krag suspected it could be something to do with SpaceX’s electric propulsion system, which “maybe is not reacting so fast” as the chemical propulsion on board Aeolus.

The article is clearly spun to make SpaceX look bad, though based on the stated facts the company shot itself in the foot quite ably. If their propulsion system could not have done the job as well as the other satellite, they should have simply said so and worked with ESA to get the issue fixed, rather than simply saying they would do nothing.

Vikram has successfully separated from Chandrayaan-2

The new colonial movement: India’s lunar lander, Vikram, has successfully separated from Chandrayaan-2, and is functioning nominally in lunar orbit.

The update describing this is the second update at the link, with the first detailing the arrangements for the press to cover the landing on September 7.

The lander carries the rover, dubbed Pragyan, which will roll off Vikram only a few hours after landing.

China launches two smallsats

Using its Kuaizhou-1A solid rocket, China’s pseudo-private company ExSpace launched two smallsats into orbit yesterday.

This rocket, using technology developed for the military, including a mobile launch platform, is designed to compete directly with Rocket Lab and the other western private smallsat rockets trying to come on line right now. Its development appears to have been wholly funded by the Chinese government, which revealed after the launch that they plan between 8 and 9 more launches before the end of the year.

The leaders in the 2019 launch race:

14 Russia
14 China
10 SpaceX
6 Europe (Arianespace)
4 India
4 Rocket Lab
4 ULA

The U.S. continues to lead 19-14 in the national rankings.

FAA required SpaceX to up its insurance for Starhopper test

The FAA’s office that regulates commercial space required SpaceX to increase its insurance coverage for this week’s Starhopper test to $100 million, thirty three times higher than their coverage for the previous Starhopper hops.

Lots of information at the link, though in summary it all makes perfect sense.

There are a number of likely reasons the federal regulator required SpaceX to boost its insurance coverage, says George Nield, a former FAA associate administrator who led its Office of Commercial Space Transportation (OCST) for more than a decade.

One is that Tuesday’s launch took Starhopper hundreds of feet higher than in July; during the prior flight, SpaceX’s vehicle only went about 60 feet (18 meters) up before landing. “The higher you want to go, the more propellant you’re going to have to load, and the more propellant you load, the bigger the boom if it were to explode,” Nield told Business Insider prior to Tuesday’s launch.

More importantly, their Boca Chica launch site is only a mile and a half from a small village of about twenty people, much closer than any other launchpad in the world. How SpaceX will manage this issue should they wish to test fly their fullscale Starship prototype from this site I really do not know. It could be that they won’t, and will confine all test flights to Kennedy, where they are also building a second Starship prototype.

Russia’s Rockot launches military geodesic satellite

Russia today used its re-purposed ballistic missile, Rockot, to launch the second in a two-satellite constellation of military geodesic satellites, designed to more accurately map the Earth’s gravitational field.

This launch puts Russia in the lead in the annual race for most launches for the first time since 2018. It also gives them more launches for the year than they had predicted. Both facts demonstrate that their launch industry is showing a recovery from the problems experienced in 2016, when they discovered corruption in one of their main rocket engine companies, requiring the recall of all engines.

The leaders in the 2019 launch race:

14 Russia
13 China
10 SpaceX
6 Europe (Arianespace)
4 India
4 Rocket Lab
4 ULA

The U.S. still leads Russia in the national rankings, 19 to 14.

Apparent Iran launch failure

Just released satellite photos showing fire and smoke at an Iranian launchpad suggest that a rumored attempt by Iran this week to launch a satellite into orbit resulted instead in a launchpad failure.

[S]atellite images by Planet Labs Inc. showed a black plume of smoke rising above a launch pad there, with what appeared to be the charred remains of a rocket and its launch stand. In previous days, satellite images had shown officials there repainted the launch pad blue.

On Thursday morning, half of that paint apparently had been burned away. “Whatever happened there, it blew up and you’re looking at the smoldering remains of what used to be there,” said David Schmerler, a senior research associate at the Middlebury Institute of International Studies.

Schmerler told The Associated Press that the images of the space center suggested that the rocket either exploded during ignition or possibly briefly lifted off before crashing back down on the pad.

In July Iranian officials had said they would do three launches this year, with a communications satellite launch expected before the end of the summer. It would appear that this failure is of that launch.

SpaceX begins hunt for Starship landing sites on Mars

Candidate landing sites for SpaceX's Starship

In the August image release from the high resolution camera of Mars Reconnaissance Orbiter (MRO) were five images whose title immediately caught my interest:

The overview map on the right shows the location on Mars for these five photographs. The second and third images are of the same location, taken to produce a stereo pair.

To put it mildly, it is most intriguing to discover that SpaceX is beginning to research a place where it can land Starship on Mars. I immediately emailed Nathan Williams, the JPL scientist who requested these images from SpaceX, but he was bound by a non-disclosure agreement with SpaceX and could not comment. I have since tried to get some information directly from SpaceX but so far the company has not responded. A 2017 news story had indicated the company’s interest in this Mars’ location, but gave no details either.

Based on what we now know of Mars, however, it is possible to figure out why they favor this location, on the border between the two large northern lowland plains Arcadia and Amazonis Planitia.

What Starhopper achieved

Starhopper in flight
Click for full image.

Captalism in space: While most news reports (including mine yesterday) have focused on the spectacular 150-meter flight of Starhopper, the real story here is the Raptor engine. As one of my readers said most succinctly in a comment:

As impressive as the flight was, there is so much more going on here. This is the most efficient rocket engine ever, with all fuel and LOX running through the combustion chamber – including exhaust from the turbopumps. The Russians tried it, and NASA tried it, but this is the first time such a design has flown. It’s also the first major engine using methane, so SpaceX is learning all the ground support processes for storing, fueling, and detanking methane (mostly) safely. (Still causing grass fires at launch…) They’re aiming for production cost below $2M per Raptor, and they’re about ready to go full production on the engines, around 500 engines per year.

In fact, Musk himself reveals the truth of Diane Wilson’s comment in a tweet, found in this news story about yesterday’s flight:

Starhopper’s flying days may be done, but the stubby prototype will be retasked rather than put out to pasture.

“Yes, last flight for Hopper. If all goes well, it will become a vertical test stand for Raptor,” Musk said via Twitter on Saturday.

In a sense, yesterday’s flight was no different. Starhopper was essentially a flying test stand for Raptor, which is in itself an incredible concept, when you think about it. Now it will continue to be used as a test stand, but will no longer fly.

I have been told by rocket engineers more than once that you need to build and test your engine before you can really start your rocket design. Once you know its capabilities you can then design and construct the rocket.

This is why Virgin Galactic’s SpaceShipTwo has generally been a failure. They built the ship before the engine, and when the engine had issues they had to improvise redesigns that have limited the ship’s capability and seriously delayed its launch.

SpaceX now has its engine ready. Construction on its two prototype Starships, in Boca Chica and Florida, will now proceed quickly. Based on how quickly it took SpaceX to do the first Starhopper test flights (announced in late 2018 and flying in about eight months), expect test flights within six to eight months. (Note that in this last link I expressed doubt they could get those Starhopper flights off in 2019. SpaceX proved me wrong.)

Finally, a minor news note: SpaceX today successfully brought a Dragon cargo capsule back to Earth after a month at ISS, completing its third flight in space. That this multi-use flight is hardly mentioned in the news illustrates how far SpaceX has reshaped space engineering in only a few years.

Starhopper: Success!

Starhopper in flight
Click for full image.

It appears today’s 150 meter hop (about 500 feet) of SpaceX’s Starhopper prototype was a complete success. To the right, and also below, are screen captures grabbed by me from one private live stream as well as from SpaceX’s own live stream.

In fact, this quick hop appears to have gone amazingly smoothly. It launched almost exactly at the target time, and landed quite softly on the launchpad, as intended. You can see the nozzle of the Raptor engine shifting and adjusting throughout the flight, also another indication that their engineering here is working perfectly. Congratulations SpaceX!

I have embedded SpaceX’s video below the fold. The flight begins around 30 minutes in.

Starhopper test flight scrubbed

The planned 150-meter-high test flight of SpaceX’s Starhopper test prototype was aborted at T-0 seconds last night when the Raptor engine did not ignite as expected.

A live video feed provided by SpaceX showed the squat, 30-foot-wide (9-meter) Starhopper vehicle counting down to a planned liftoff shortly after 6 p.m. CDT (7 p.m. EDT; 2300 GMT) Monday from the company’s facility in South Texas. The vehicle’s single methane-fueled Raptor engine could be seen swiveling side-to-side in a preflight steering check, as the Starhopper pad’s sound suppression system dumped water under the vehicle.

But the Raptor engine did not ignite as the countdown clock reached zero.

“Test aborted just after T-0,” read a text banner on SpaceX’s webcast. “Teams evaluating next test opportunity.”

They say they will try again today. If you want to watch this link provides some suggestions.

These test flights are testing the Raptor engine more than they are testing vehicle take-off and landing. This engine is a significant advancement from not only SpaceX’s Merlin engine but from almost every rocket engine previously built. It has the potential to set the record for the most efficient and powerful engine. It is therefore not unexpected that there will be issues during these test flights.

Planned Starhopper test shuts down Boca Chica

SpaceX’s planned next hop of its Starhopper test vehicle is apparently forcing local residents from their homes, as well as threatening damage to buildings as much as two miles away.

Those residents live in tiny Boca Chica Village, Texas, which sits less than 2 miles (3 km) from a SpaceX-operated launch site near the US-Mexico border along the Gulf Coast. SpaceX’s test of the so-called “Starhopper”—a prototype of a reusable shuttle meant for human transit—may well create an “overpressure event” capable of breaking glass in buildings nearby. The police-delivered warnings advise residents to, at a minimum, exit their homes when they hear police sirens around the 4pm launch window.

Comments posted under the Brownsville Herald article include, “Doesn’t sound good to me that they have to evacuate their homes all because Space X is testing” and “I think spacex should be prepared to pay for the window replacements.”

The test is also forcing the closure of roads required by residents to access or leave their neighborhoods.

It seems that SpaceX’s decision to conduct their Starhopper tests in Boca Chica rather than at their McGregor, Texas, engine test facility might have been a mistake. Unlike Boca Chica, McGregor is a much larger facility, which means tests are farther away from local residences. While Boca Chica gives SpaceX great visibility (hence some great publicity) for Starhopper, it appears to also be causing some bad press because of these negative impacts on the local community.

Either way, expect news of Starhopper’s biggest hop in the next day or so.

Satellite company switches from Falcon Heavy to Ariane 5

Capitalism in space: The communications satellite company Ovzon has switched from SpaceX’s Falcon Heavy to Arianespace’s Ariane 5 for the launch of its first wholly owned satellite in 2021.

In an interview Aug. 24, Ovzon CEO Magnus René told SpaceNews the company received a more appealing launch offer from Arianespace. “It’s nothing political or anything like that, it’s not that we don’t trust SpaceX — it’s just that we could get a better deal in cost and time and so on from Ariane at this time,” René said.

SpaceX charges $100 million for a Falcon Heavy launch, about the same as Arianespace charges for one of the two berths on its Ariane 5. Arianespace must have therefore cut its standard price to make it more attractive, and win the deal.

Ain’t competition wonderful? Governments have been trying (and failing) to get us into space for half a century, using the model of international cooperation. Introduce some competition and suddenly it becomes both easier and cheaper to do it. Who woulda thunk it?

Unmanned test Soyuz aborts docking to ISS

Astronauts on ISS were forced to abort the docking of an unmanned upgraded Soyuz capsule today when it appeared to have problems locking onto its docking port.

According to NASA, Soyuz MS-14 entered an orbit above and behind the ISS, which would bring the spacecraft back into the vicinity of the outpost 24 hours later. However within an hour after the failed docking, the mission control in Korolev told the ISS crew that the next docking attempt would not be made until at least August 26 after a series of tests. Head of flight operations in Korolev Vladimir Soloviev informed the cosmonauts that ground specialists had narrowed down a potential root cause of the failure during docking to a “bad signal amplifier” in the Kurs-P avionics system aboard the station. Soloviev instructed the crew to swap the suspected amplifier for a new one and then conduct a test of the Kurs-P system. Provided the ongoing analysis confirmed the initial failure scenario and the in-orbit tests went successfully, another rendezvous attempt could be made in around 48 hours, between 08:00 and 09:00 Moscow Time on August 26. Soloviev asked the crew members whether they knew where the components in question had been located to which the cosmonauts said that they had remembered it approximately but asked for reference photos to be sent to them.

Assuming this is the same docking port the Russians have used for previous Soyuz and Progress dockings, the amplifier would have had to fail since the last docking.

UPDATE: It appears that they are instead going to use a different Russian docking port on ISS for the second docking attempt, thereby bypassing the suspect docking system.

Japan’s plan for returning Hayabusa-2’s Ryugu samples to Earth

Japan’s today provided an update on what it has done to prepare the location where Hayabusa-2’s samples from the asteroid Ryugu will land on Earth.

The landing site is in the Woomera Prohibited Area (WPA) in the outback of southern Australia. Japan has already signed an agreement with that country for the recovery, as well as done preliminary surface work

The recovery site is an Australian Government prohibited area and is not accessible to the public. As part of the preparatory work, a field survey of the proposed recovery site in the WPA was conducted with permission from the Australian Government. This preparatory work confirmed the suitability of both the proposed recovery site and the candidate site for the antenna station that will search for the capsule.

The landing of the recovery capsule is now scheduled for late in 2020.
