SpaceX launches Space Force GPS satellite

4:37 pm

Capitalism in space: SpaceX tonight successfully launched the GPS satellite that on a previous launch had experienced a launch abort at T-2.

This was a completely new Falcon 9 rocket, with two of its original engines replaced after the company had traced the issue that caused the launch abort. The first stage successfully landed on the drone ship in the Atlantic Ocean, and will fly again on the next GPS launch by SpaceX for the Space Force.

The satellite has been deployed successfully, completing the launch.

The leaders in the 2020 launch race:

27 China
19 SpaceX
12 Russia
4 ULA
4 Europe (Arianespace)
4 Rocket Lab

The U.S. now leads China 30 to 27 in the national rankings.

SpaceX finds clogged valves in several Merlin engines

5:56 am

Capitalism in space: SpaceX has discovered that the problem that caused a recent launch abort of a GPS satellite was a coating that clogged valves in several newer Merlin engines.

Hans Koenigsmann, vice president of build and flight reliability at SpaceX, said teams initially weren’t able to figure out why two of nine engines triggered early-start sensors on Oct. 2, which forced computers to automatically scrub seconds before liftoff. After the engines were removed and shipped to Texas for testing, the anomaly surfaced again when sensors detected higher-than-expected engine chamber pressures.

The cause: a minuscule, almost undetectable amount of “masking lacquer,” which is used to protect engine components and surfaces during the production process. The lacquer is almost like a bright red nail polish. “We found a relief valve – a little line that goes to the relief valve – blocked in the gas generator,” Koenigsmann told reporters Wednesday. “That little red substance was blocking a relief valve that caused it to function a little bit earlier than it was supposed to.”

The gas generators are almost like little rocket engines themselves – they’re used to power a pump that then feeds propellants into the main engine chamber. But the blockage caused certain processes to begin too early.

Once the lacquer was removed the engines functioned perfectly.

The issue was also found in two engines on the new booster that was going to launch astronauts to ISS, which explains why that mission was delayed. The company is swapping out the engines, and is still targeting November 14th for that launch. In addition, NASA wants it to fly at least two missions beforehand to demonstrate the problem is fixed. One will be that GPS satellite, on November 4th. The other could be one of three different payloads on SpaceX’s busy schedule.

Initial price for Starlink: $99 per month?

10:43 am

According to a CNBC article today, SpaceX is now offering a beta version of its Starlink internet service to customers as the price of $99 per month, plus a $499 charge for equipment.

SpaceX is expanding the beta test of its Starlink satellite internet service, reaching out via email on Monday to people who expressed interest in signing up for the service.

Called the “Better Than Nothing Beta” test, according to multiple screenshots of the email seen by CNBC, initial Starlink service is priced at $99 a month – plus a $499 upfront cost to order the Starlink Kit. That kit includes a user terminal to connect to the satellites, a mounting tripod and a wifi router. There is also now a Starlink app listed by SpaceX on the Google Play and Apple iOS app stores.

“As you can tell from the title, we are trying to lower your initial expectations,” the emails said, signed Starlink Team. “Expect to see data speeds vary from 50Mb/s to 150Mb/s and latency from 20ms to 40ms over the next several months as we enhance the Starlink system. There will also be brief periods of no connectivity at all.”

SpaceX did not confirm this story with CNBC. If it is real, the price is disappointingly high, and might very well limit Starlink’s potential. Then again, this is only the beta version. Later versions when under full operation and available to many more customers might bring that price down.

SpaceX identifies problem with several engines on booster, requiring replacement

9:51 am

Capitalism in space: SpaceX has identified the issue with several engines on the first stage that caused a launch abort for an Air Force GPS satellite and has replaced those engines.

Since Falcon 9 B1062 suffered a rare last-second launch abort on October 2nd, SpaceX has discovered an issue with several new Merlin 1D booster engines and apparently removed affected engines from Falcon 9 booster B1062, shipped the engines to McGregor, Texas for testing, characterized the bad behavior, and implemented a fix capable of satisfying their strictest customers (NASA and the US military) in roughly three weeks.

The immediate fix appears to be replacing the engines for now as they troubleshoot the issue. They have now rescheduled the launch of the GPS satellite for November 5th.

It also appears that because the company has identified the engine issue and can spot it on any engine it uses, NASA has agreed to set a November 14th launch date for the next manned Dragon mission. They will hold a press conference tomorrow to outline the situation in more detail.

SpaceX launches 60 more Starlink satellites

9:37 pm

Capitalism in space: SpaceX today successfully launched another sixty Starlink satellites, bringing the total in orbit to over 800.

The company also recovered the first stage, completing its third flight. The fairings were to be picked up in the ocean, rather than caught in a ship’s net, as the last launch one fairing broke the net. SpaceX engineers might have determined ocean recovery is now safer and sufficient for reuse.

This was also the company’s 100th successful launch and its 63rd successful first stage recovery.

The leaders in the 2020 launch race:

26 China
18 SpaceX
11 Russia
4 ULA
4 Europe (Arianespace)

The U.S. now leads China 28 to 26 in the national rankings.

SpaceX wins partial approval to provide Starlink service in Canada

10:05 am

Capitalism in space: Though SpaceX has obtained permission to provide its Starlink internet service from Canada’s Radio-television and Telecommunications Commission, similar to the U.S.’s FCC, it still has not gotten full government approval to begin offering its service to customers.

It appears a different Canadian regulatory body, dubbed Innovation, Science and Economic Development Canada (ISED), has still not given its okay of the “satellite spectrum” SpaceX requires. From the second link:

SpaceQ had previously contacted ISED in June about SpaceX. ISED wouldn’t comment directly on any application, but did tell SpaceQ that the applications and approved website pages were up to date at that time. The website had last been updated in May. Since then, the website was updated in July. And yet there’s still no mention of SpaceX. It’s my understanding that the specific pages with applications and approvals is updated pretty quickly when there is new information to post. Though it took 3 weeks for changes to appear after Kepler submitted their application in June of this year.

With respect to how long it takes to get approval, ISED said the “service standard for the processing of satellite applications, including for those for foreign satellites, is 130 calendar days.” It’s quite possible that it could take longer.

This description carries all the hallmarks of a typical government bureaucracy whose only purpose is to block new companies and new technology. The political swamp of Canada might also be using it as a means of extortion for campaign funds from SpaceX. “Nice business you got there. Sure would be a shame if it didn’t get that license approval.”

I don’t think SpaceX needs to bow to these games. In the end ISED will back down and give approval, especially when the company begins offering its services just over the border in the U.S. The competitive and political pressure to give its okay will then be too great.

SpaceX launches another 60 Starlink satellites

10:18 am

Capitalism in space: SpaceX today successfully launched another 60 Starlink satellites, raising the constellation to more than 800 satellites.

The first stage successfully landed, for the sixth time, on a drone ship. The company also recovered both fairings, which were making their third flight. With one fairing’s recovery however the net broke on the ship, which might have damaged it this time.

The leaders in the 2020 launch race:

26 China
17 SpaceX
11 Russia
4 ULA
4 Europe (Arianespace)

The U.S. had regained the lead over China, 27 to 26, in the national rankings.

Next manned Dragon launch delayed

11:54 pm

Because of an engine issue that caused Falcon 9 launch of a military GPS satellite to abort at T-2 seconds on October 2nd, SpaceX and NASA have decided to delay the next manned Dragon launch from October 31st “to early-to-mid November.”

The one to two week delay will give the company time to analyze the issue involving an “unexpected pressure rise in the turbomachinery gas generator” that are used to drive the rocket’s Merlin engine turbopumps.

It seems unlikely that this problem is systemic to all Merlin engines, considering the number of rocket launches SpaceX has successfully completed in the last four years. Each launch has used ten engines, with no evidence of this problem appearing previously.

At the same time, no one wants a problem on a manned flight. Better to completely understand why it happened on the GPS launch first before launching four astronauts on the rocket.

Musk to personally review SpaceX launch procedures

8:51 am

Capitalism in space: As a result of the spate of launch aborts in the past few weeks, the head of SpaceX, Elon Musk, is now planning a personal review of the company’s launch facilities in Florida next week.

Musk would like SpaceX to increase its cadence such that it can reach 48 launches in 2021, which would more than double the company’s previous record for total number of missions in a single year. Technical scrubs like the ones this week would prevent this. Achieving frequent launches will require smooth operations.

“We’re doing a broad review of launch site, propulsion, structures, avionics, range & regulatory constraints this weekend,” Musk tweeted. “I will also be at the Cape next week to review hardware in person.”

This review aligns with the company’s entire strategy regarding rocketry. Instead of accepting such aborts as the cost of doing business, Musk wants to review procedures to see if launches can be made more reliable.

Musk’s statement that they want to be able to do 48 launches next year is most intriguing, as it suggests, based on their manifest of launches, that they are going to launch a lot of Starlink satellites.

SpaceX launches another 60 Starlink satellites

8:20 am

After a number of weather delays, SpaceX this morning finally launched another 60 Starlink satellites into orbit, using its Falcon 9 rocket.

They also successfully landed the 1st stage, on its third flight, the 61st time they have done this. One fairing half was also making its third flight, and was also recovered. I have embedded the live stream of the launch below the fold.

The leaders in the 2020 launch race:

25 China
16 SpaceX
10 Russia
4 ULA

Antares launches; Falcon 9 aborts

8:55 pm

Of the two launches scheduled for tonight, Northrop Grumman’s Antares rocket was the only one to launch, lifting off on schedule at 9:16 pm (Eastern). This was the company’s third launch this year.

SpaceX’s launch however aborted at T-2 seconds. No word on why the rocket’s computer’s shut down, or when they will reschedule.

The leaders in the 2020 launch race remain unchanged:

25 China
15 SpaceX
10 Russia
4 ULA
4 Europe (Arianespace)

The Antares launch however puts the U.S. back into a tie with China, 25-25, in the national rankings.

Two launches scheduled for tonight, 27 minutes apart

9:08 am

The numerous launch scrubs this past week has created an unprecedented situation tonight, two orbital launches scheduled only 27 minutes apart from two different East Coast spaceports.

First Northrop Grumman will try again to launch its Cygnus cargo freighter to ISS from Wallops Island, Virginia, with the launch scheduled for 9:12 pm (Eastern). The first launch attempt last night was aborted 2:21 seconds before liftoff “after receiving off-nominal data from ground support equipment.”

Second, SpaceX will try to launch two Air Force GPS satellites from Cape Canaveral, Florida, with the launch scheduled for 9:43 pm (Eastern). This launch has been delayed several times because of the repeated launch scrubs of ULA’s Delta 4 Heavy rocket, attempting to launch a military reconnaissance satellite. ULA’s launch had priority for the range, but with it delayed due to the investigation over the T-7 second launch abort on September 30th, the SpaceX’s GPS launch moves up in line.

The first will be live streamed on NASA TV, the second by SpaceX. I have embedded the live streams for both below the fold.

Crew for next Dragon manned flight name capsule “Resilience”

10:11 am

Capitalism in space: The crew for next Dragon manned flight, scheduled now for October 31st, have given the capsule the name “Resilience.”

Before arriving at Resilience, Hopkins and his crewmates filled a whiteboard with a long list of “good ideas” for their spacecraft’s name and then narrowed down their choices, he said.

“We wanted to make sure that the name fit,” Hopkins said in an interview with collectSPACE, following Tuesday’s press conference. “We got it down to two or three names and they were all very close in terms of that we liked them and could have been really happy with them, [but] at the end of the day, it was the one that just felt right.”

The crew of the first Dragon manned capsule named it Endeavour, to honor the shuttle spacecraft they had both flown in. The names of these capsules is not merely symbolic. Both capsules will be reused, like the shuttles, and thus deserve names to mark them when they fly again.

What is not clear yet is exactly how many capsules SpaceX will build, nor exactly how many times each capsule will be reused. The latter will of course help determine the former. It will take a few years and multiple flights to find out. Eventually however SpaceX will have its own fleet of manned spaceships, available not only to NASA but to private customers.

SpaceX launch aborts at T-18 seconds

9:00 am

Capitalism in space: SpaceX’s attempt to launch another 60 Starlink satellites today aborted at T-18 seconds due to what they called “out-of-family ground sensor reading.”

They have not announced a new launch date as yet.

The U.S. has had little luck getting any of its launches off in the past month. Many have been delayed or scrubbed, for either technical reasons or weather. Hopefully tonight’s launch of Northrop Grumman’s Cygnus cargo freighter to ISS will avoid these issues and get off the ground.

Changes in engineering and procedures for next manned Dragon flight

4:27 pm

SpaceX is making several engineering and operational changes involving flights of its manned Dragon capsule, based on the company’s experience during the first manned flight several months ago.

First, they are reinforcing the heat shield in one area.

After a successful test flight that ended when NASA astronauts Bob Behnken and Doug Hurley splashed down in the Gulf of Mexico on Aug. 2, the company noticed “a little more erosion than we wanted to see” in a few areas of the capsule’s heat shield, Hans Koenigsmann, SpaceX’s vice president of build and flight reliability, said during a press call this week. He said there “was nothing to be concerned with at all times. The astronauts were safe, and the vehicle was working perfectly.”

Second, they are revising the software used to determine the altitude when the capsule’s drogue parachute is released.

Koenigsmann said the company is refining how it measures the capsule’s altitude as it returns to Earth. During the August test flight, the drogue parachutes deployed at a slightly lower altitude than the company expected, but still well within safety parameters, he said.

Finally, they are going to more strictly enforce a 10-mile “keep-out zone” in the ocean where the capsule splashes down. They do not want to see another crowd of recreational boats swarming the landing zone, as happened when the capsule returned to Earth in August.

NASA & SpaceX set Oct 31st for next manned Dragon mission

9:22 am

Capitalism in space: NASA and SpaceX have now scheduled Oct 31st as the target launch date for the first operational manned Dragon mission to ISS, the second manned Dragon mission overall.

This new date delays the launch a week from the previous announced schedule, and was done to give some space between its launch and the launch of a manned Soyuz on October 14th and the return of a different Soyuz with the present ISS crew on October 21st.

China and Russia launch a bunch of satellites

8:40 am

Russia today used its Soyuz-2 rocket to launch three communication satellites plus 19 commercial smallsats.

This was the first time Russia used the Soyuz-2 for these particular small communications satellites, as previously they had been launched by a variety of smaller rockets.

China in turn today used its Long March 4B to place two Earth resource satellites into orbit.

The leaders in the 2020 launch race:

25 China
15 SpaceX
10 Russia
4 ULA
4 Europe (Arianespace)

China has moved ahead of the U.S. 25 to 24 in the national rankings.

These numbers should change again in the next few days. The U.S. has had a number of scrubs and launch delays in the past few days. ULA has been repeatedly pushing back the previously delayed launch of a National Security Agency reconnaissance satellite due to a variety of problems related to its Delta 4 Heavy rocket. The launch is now set for just after midnight tonight (Monday night). [UPDATE: Launch scrubbed due to lightning and poor weather. Tentatively rescheduled for 11:58 pm (Eastern) on September 29.]

SpaceX meanwhile had to scrub a launch this morning (September 28) of another 60 Starlink satellites due to weather. No new launch date has yet been announced.

Northrop Grumman also has had to scrub tomorrow’s Antares launch of a Cygnus cargo freighter because of poor weather at Wallops Island. It is now set for the evening of October 1st.

SpaceX also has a scheduled launch tomorrow morning of a GPS satellite on its Falcon 9 rocket. This is also threatened by weather. There is also no word whether the ULA launch scrub will cause this launch to be delayed.

Axiom, SpaceX, and NASA finalizing first wholly private manned mission

12:38 pm

Capitalism in space: Axiom, SpaceX, and NASA are close to finalizing the deal for the first wholly private manned mission to ISS, tentatively set for October 2021.

One of the topics Axiom is negotiating with NASA involves how much insight the space agency will have into the private astronaut mission. While the Axiom missions will be managed by commercial companies, the AX-1 flight will fly with a reusable Crew Dragon spacecraft that will carry NASA astronauts on other missions. “There’s a certain amount of insight (NASA) would like on our flight, on a commercial flight,” [Axiom official] Suffredini said Friday. “So that is one aspect of that process. We’re using a vehicle that is going to be re-flown, and NASA will certify the re-flights because they want to do re-flights.”

Axiom and SpaceX will also have to confirm a schedule with NASA for the AX-1 mission to dock with the space station. The orbiting research complex has a busy schedule of arriving and departing crew and cargo vehicles, and managers also have slot in spacecraft dockings amid spacewalks, experiments, and other critical operations.

NASA also oversees safety of the space station with the program’s international partners.

The private companies however will in the end be responsible for the flight.

There have been rumors that the passengers on this flight will be Tom Cruise and his film director, though this is not confirmed. Also, these same arrangements will be used for the tentative 2023 private flight of the winner of a proposed reality television show dubbed Space Hero.

Reality show to fly contestant to ISS

10:35 am

Capitalism in space: A new reality show, dubbed Space Hero, will have audiences watch contestants compete to be a passenger on a private capsule, likely SpaceX’s Dragon, and fly to ISS for ten days.

The selected group of contestants will undergo extensive training and face challenges testing their physical, mental and emotional strength, qualities that are essential for an astronaut in space. I hear the idea is for the culmination of the competition to be in a an episode broadcast live around the world where viewers from different countries can vote for the contestant they want to see going to space. The show will then chronicle the winner’s takeoff; their stay at the ISS for 10 days alongside professional astronauts traveling at 17,000 mph, orbiting the Earth 16 times a day; and end with their return to Earth. The Space Hero company is currently in discussions with NASA for a potential partnership on STEM initiatives onboard the ISS.

The trip of the Space Hero winner is expected be on a SpaceX Dragon rocket though a launch provider is yet to be officially selected. Space Hero, billed as the first space media company, is working with Axiom Space, manufacturer of the world’s first privately funded commercial space station — a module for the ISS where the private astronauts can stay — and full-service human spaceflight mission provider.

The project seems more viable and realistic than previous such attempts, aided by the fact that tickets can now be purchased on a private and operational manned capsule.

SpaceX successfully launches Argentina satellite

4:37 pm

Capitalism in space: SpaceX tonight successfully launched an Argentinian radar satellite into polar orbit, the first such launch from Cape Canaveral since the 1960s.

The company also successfully landed the first stage at the Cape, completing that stage’s fourth flight. As I write this they still have two more smallsats to deploy, but it is very unlikely they will have an issue doing so.

The leaders in the 2020 launch race:

20 China
14 SpaceX
9 Russia
4 ULA

The U.S. now leads China 22 to 20 in the national rankings. With a scheduled launch by Rocket Lab from New Zealand later tonight, these numbers could change again before the day is out.

Confirmed: SpaceX plans two launches for tomorrow

1:02 pm

Capitalism in space: SpaceX has now confirmed that it will attempt two Falcon 9 launches tomorrow at its launch facility at Cape Canaveral, the first to launch 60 Starlink satellites at 10:12 am (Eastern) and the second to launch an Argentinian radar satellite at 7:18 pm (Eastern).

In the first launch the first stage, used once before, will attempt to land on the drone ship in the Atlantic. On the second launch the first stage, used three times previously, will return to Cape Canaveral for its landing attempt.

The live stream for both will be available here.

SpaceX will also tomorrow attempt a 500 meter hop of its sixth Starship prototype. The live stream of that can be seen here.

Meanwhile Rocket Lab has shifted its launch this weekend in New Zealand from tonight to tomorrow night at 11:05 pm (Eastern). The live stream will be aired here.

That means on August 30, 2020 there could be three American launches as well as another test flight of a new reusable rocket.

Note: Astra has delayed the first orbital test flight of its rocket to no early than September 10th due to poor weather in Kodiak, Alaska.

SpaceX wins launch contract for unmanned lunar lander

11:24 am

Capitalism in space: Masten Space Systems has awarded SpaceX the launch contract for its unmanned lunar lander, being built to carry nine NASA science payloads to the south pole of the Moon.

Launch is tentatively scheduled for late ’22.

NASA will be an anchor customer for the mission but Masten intends to sign up others. “There is a tremendous amount of interest,” he said, including from both the public and private sector, although he didn’t mention any specific potential customers.

Mahoney said the level of customer interest soared after Masten won the CLPS award and had a firm schedule for the mission. “Once the CLPS award was made and we crossed from speculative to having a schedule, the tenor and tone of our conversations have changed dramatically.”

The limiting factor for the lander mission has not been the amount of mass available for payloads, he said, but instead positions on the lander that have views of the surface desired by payloads. “There’s a game of positioning among the various instruments so that they can get the view angles that they need and not interfere,” he said.

However, he said the company isn’t considering major changes in the lander’s design to accommodate payloads. “The design principle is the ‘pickup truck’ that can haul a bunch of different things,” he said. “We’re trying to escape the completely unique, bespoke system that does one job and one mission really well.”

I guarantee that at least one university student-built payload will end up on the lander.

Five American launches in two days!

9:51 am

Capitalism in space: Though the first launches in the string of four American launches that was initially scheduled to begin two days ago and continue through the weekend was delayed because of weather and then technical issues, all these delays have done is pack those scheduled launches into a shorter time period, with the addition of a fifth launch!

If all goes as scheduled (hardly guaranteed), we will see five launches from three spaceports and four private companies in less than two days. The schedule, as of this moment:

August 29th at 2:04 am (Eastern): ULA’s Delta 4 Heavy to launch a military reconnaissance satellite from Cape Canaveral. The company’s webcast of the launch can be seen here.

August 29th at 11:05 pm (Eastern): Rocket Lab’s Electron rocket will launch a commercial radar satellite from New Zealand. The launch can be watched at the company’s live stream channel.

August 30th at 10:08 am (Eastern): SpaceX’s Falcon 9 will launch more of its Starlink satellites from Cape Canaveral. All SpaceX launches are live streamed from SpaceX’s website, though the links are not yet up.

August 30th at 7:19 pm (Eastern): SpaceX’s Falcon 9 will launch an Argentinian Earth observation satellite from Cape Canaveral. All SpaceX launches are live streamed from SpaceX’s website, though the links are not yet up.

August 30th at 10:00 pm (Eastern): Astra will attempt the first orbital test launch of its privately built rocket from Kodiak, Alaska. They will not be live streaming their launch, but will provide updates at their Twitter feed.

All times and dates list only the beginning of the launch windows, which means they might launch, but not exactly at the times listed.

Also, SpaceX is aiming to do its second Starship test hop this weekend, the first for its sixth prototype.

Delta 4 Heavy launch scrubbed

11:15 pm

Tonight’s launch of ULA’s Delta 4 Heavy was scrubbed due to a variety of technical problems. They have not set a new launch time, though they say they are aiming for the early morning hours of August 28.

This was to have been the first of four American launches in the next four days. The next, a Falcon 9 launch of an Argentinian radar Earth observation satellite, was scheduled for tomorrow, August 27th, at 7:19 pm (Eastern). No word on whether it is going forward as planned, though it might be since the ULA launch has shifted after it, to August 28th.

The third, by Rocket Lab, is presently scheduled also for August 28rd at 11:05 pm (Eastern), launching out of New Zealand.

The fourth, another SpaceX launch of more Starlink satellites, had been scheduled for 10:30 am (Eastern) on August 29th. Once again, this schedule could change due to tonight’s ULA scrub.

Stay tuned. I suspect all three companies are going to aggressively work to get all four launches off as fast as possible, even if not exactly as presently scheduled.

Four American launches in the four days

9:39 am

UPDATE: Rocket Lab’s launch has been delayed to 11:05 pm (Eastern) August 28 due of weather.

Beginning tomorrow, the next four days will be very busy for the American space rocket industry, with three companies attempting to complete four different launches.

First comes Rocket Lab, which will attempt its first launch of its Electron rocket since its first operational launch failure on July 4. Launch is scheduled for 11:05 pm (Eastern) on August 26th.

Next ULA is scheduled to use its most powerful rocket, the Delta 4 Heavy, to put a National Reconnaissance Office surveillance satellite into orbit. Launch is set for 2:12 am (Eastern) on August 27th. This very expensive rocket (which costs three to four times that of a Falcon Heavy) has only four launches left before being permanently retired.

Then SpaceX will attempt two launches in quick succession. The first will launch at 7:19 pm (Eastern) on August 27th, putting up an Argentinian Earth observation radar satellite. On this launch the first stage is a new one, and will attempt the first landing at Cape Canaveral since March 2020.

SpaceX will then follow with its third Starlink launch this month and twelfth overall, scheduled for 10:30 am (Eastern) on August 29th out of its facility at Cape Canaveral, assuming the other launches at Kennedy go as planned.

Moreover, the startup smallsat rocket company Astra is also aiming to attempt its first test launch before the end of August. The date is not yet set.

Busy times for sure, but note that this is only the beginning. I expect by the end of the 2020s the launch schedule will get increasingly packed. Soon having three three launches per week will seem routine.

Musk: 100+ reuses of Falcon 9 1st stages possible

8:25 am

Capitalism in space: According to Elon Musk:, based on what SpaceX has learned so far in reusing the 1st stages of its Falcon 9 rocket, it is entirely possible that the present design could result a hundred or more reuses.

Now, with all that experience in hand and a Falcon 9 Block 5 booster already 60% of the way to the ten-flight reuse milestone, Musk says that “100+ flights are possible” and that “there isn’t an obvious limit.” While “some parts will need to be replaced or upgraded” to achieve dozens or hundreds of booster reuses, Musk says that SpaceX “almost never need[s] to replace a whole [Merlin 1D] engine.

Given that a Falcon 9 booster’s nine M1D engines are likely the most difficult part of each rocket to quickly and safely reuse, it’s extremely easy to believe that individual boosters can launch dozens – if not hundreds – of times with just a small amount of regular maintenance and repairs. In that sense, SpaceX has effectively achieved Musk’s long-lived dream of building a rocket that is (more or less, at least) approaching the reusability of aircraft.

The next step in this effort will be to shorten the turnaround times. At the moment the best time between any booster’s reflight has been just under two months. SpaceX has said they want to be able to refly boosters in just days.
