SpaceX launches commercial radio satellite with reused Falcon 9

9:58 pm

Capitalism in space: SpaceX tonight successfully launched a Sirius-XM commercial radio satellite using its Falcon 9 rocket.

The first stage, making its third flight, successfully landed on the drone ship in the Atlantic. Note too that this launch took place only three days after SpaceX’s previous launch. Watching it take place, I was struck by how completely routine everything seemed. While rocketry will never be easy, SpaceX now makes it look so, and they do so because, unlike all other rocket companies, they did not stop upgrading and improving their rocket once it became somewhat reliable. Instead, they focused on making it more reliable than any rocket ever by making it reusable. That effort has now paid off, giving them a rocket that works like clockwork, practically every time.

SpaceX successfully launches cargo Dragon to ISS

10:52 am

Capitalism in space: SpaceX today successfully launched a cargo Dragon to ISS.

The first stage booster successfully landed on its drone ship in the Atlantic Ocean.

This Falcon 9 rocket and Dragon capsule were entirely new, making their first flights. This was the first new Falcon 9 to fly since November 2020, with sixteen launches during that period using reused boosters exclusively.

In fact, since November 2020 SpaceX has completed a total of 21 launches, all done in less than seven months. Moreover, the company has scheduled 34 (!) more launches through the rest of the year. If they achieve this ambitious schedule, they will complete 51 launches in ’21, more than doubling their previous annual record of 25 set last year. With all other American companies added in, there will be a good chance the United States launch total could exceed 70, breaking the country’s own annual launch record set in 1966 at the height of the first space race.

Axiom strikes tourist deal with SpaceX for three more flights

9:48 am

Capitalism in space: Axiom today announced that it had signed a deal with SpaceX to use its Dragon capsule and Falcon 9 rocket to launch three more manned tourist missions following the first now scheduled for January.

Ax-1, Axiom’s historic first private ISS mission, has already been approved by NASA and targeted for launch to the ISS no earlier than Jan. 2022, also aboard Dragon as a result of a deal the companies signed in March 2020. Axiom last week revealed legendary astronaut Peggy Whitson and champion GT racer John Shoffner would serve as commander and pilot on its proposed Ax-2 mission – now confirmed to be a Dragon flight.

So, too, are Ax-3 and Ax-4.

Other than Whitson and Shoffner, the company has not revealed who will fly on those three additional flights. That it made this deal however strongly suggests that it has ample demand for seats and will fill those capsules with no problem.

The press release also reiterates the company’s space station plans. They will begin attaching their own modules to ISS in ’24, with the goal of detaching from the station in ’28 and operating as an independent entirely private station thereafter.

SpaceX successfully launches another 60 Starlink satellites

12:15 pm

Capitalism in space: SpaceX today successfully used its Falcon 9 rocket to place another sixty Starlink satellites in orbit, bringing that constellation to over 1,700 in orbit.

The first stage was making its second flight, and landed successfully on the drone ship in the Atlantic. Both fairings were reused, with one making a record fifth flight. Though the rocket has not yet deployed the satellites as I write this, it is expected in about a half hour and based on past history, should proceed with no problems. If there is an issue I will report it immediately.

Axiom announces astronaut to command its second commercial manned flight

1:30 pm

Capitalism in space: Axiom has announced that retired NASA astronaut Peggy Whitson will command its second commercial manned flight.

Whitson was the first woman to command the International Space Station and the oldest woman to fly in space (57, in 2017). She holds the U.S. record for most cumulative time in space (665 days) as well as the world record for most spacewalks by a woman (10).

Joining her will be 65-year-old John Shoffner, an airplane pilot and a champion car racer.

No word yet on when this flight will take place, but expect them to aim for next year, as soon as possible after Axiom’s first ISS commercial flight in January. Scheduling will also depend on NASA, which is presently working out an ISS scheduling policy to manage the increasing number of private missions being offered.

The flight will likely use a SpaceX Dragon capsule, which means there is room for two more passengers. It is possible that those seats will be filled with the winners of Discovery Channel’s proposed reality show, but they also might be filled by actor Tom Cruise and a movie director, both of whom have expressed interest in filming scenes of a movie on ISS.

SpaceX grabbing 90% of the launch contracts to the Moon

10:37 am

Capitalism in space: The announcement yesterday by Firefly that it has awarded SpaceX the launch contract for its Blue Ghost lunar lander mission (scheduled for launch in ’23) is significant because it continues a remarkable pattern of dominance by SpaceX of the lunar launch market.

Right now, of the seven scheduled robot missions to the Moon, SpaceX will launch all but one. The full list, in no particular order:

In addition, SpaceX launched Israel’s Beresheet lander in 2019 on a Falcon 9.

Furthermore, SpaceX has won the contract from NASA for the agency’s first manned lunar lander, using Starship. It has also won the contract to launch the initial components of NASA’s Lunar Gateway space station on a Falcon Heavy.

There are other lunar missions in the works (by Russia, China, and others), but these are all the launches awarded as commercial contracts to private rocket companies in recent years. Thus, of these ten lunar missions, SpaceX has launched or is launching nine. That’s a 90% market share!

Flash! SpaceX to use a NEW Falcon 9 1st stage!

9:48 am

Both side boosters landing during the 1st Falcon Heavy launch
Both side boosters landing during
the 1st Falcon Heavy launch

Capitalism in space: For the first time in since September 2020, SpaceX has delivered a new Falcon 9 1st stage to its Florida launch site in preparation for launch.

This new stage will be used on the June 3rd launch of a cargo Dragon freighter to ISS.

What is remarkable about this story is that it is news that SpaceX is using a new first stage. Not only have all of their fifteen launches in 2021 lifted off with used boosters, since November 2020 they have completed nineteen launches using only used boosters.

That’s 19 launches in only six months, all with previously flown boosters!

During that time the company’s Falcon rocket division has apparently dedicated its time in upgrading and building new Falcon Heavy 1st stage boosters, in preparation for the first Falcon Heavy launches since June 2019, set for July and October later this year. I suspect the focus has been an effort to upgrade the core booster so that it will be successfully recovered this time, something that did not occur on two of the first three Falcon Heavy launches in 2018 and 2019..

Roscosmos announces two commercial tourist flights to ISS

9:49 am

Capitalism in space: Roscosmos, the government corporation that controls of all of Russia’s space industry, announced today that it will be flying two different commercial tourist flights to ISS, both occurring before the end of this year.

The first will take place in October.

Roscosmos [is] sending an actress and a director to the ISS in October with the aim of making the first feature film in space. The film, whose working title is “Challenge,” is being co-produced by the flamboyant head of Roscosmos, Dmitry Rogozin, and state-run network Channel One.

The second will take place in December, and will fly Japanese billionaire Yusaku Maezawa (the man who has already purchased a Moon mission on SpaceX’s Starship) and his assistant Yozo Hirano in a Soyuz capsule to ISS for twelve days.

Let’s review the upcoming tourist flights now scheduled:

NASA and Axiom finalize contract for private tourism flight to ISS

9:38 am

Capitalism in space: NASA today announced that it has signed the order detailing the first commercial tourism flight to ISS by Axiom, set for no earlier than January ’22.

The spaceflight, designated as Axiom Mission 1 (Ax-1), will launch from NASA’s Kennedy Space Center in Florida and travel to the International Space Station. Once docked, the Axiom astronauts are scheduled to spend eight days aboard the orbiting laboratory. NASA and Axiom mission planners will coordinate in-orbit activities for the private astronauts to conduct in coordination with space station crew members and flight controllers on the ground.

Axiom will purchase services for the mission from NASA, such as crew supplies, cargo delivery to space, storage, and other in-orbit resources for daily use. NASA will purchase from Axiom the capability to return scientific samples that must be kept cold in transit back to Earth.

SpaceX will transport the four Axiom astronauts to and from ISS in a Dragon capsule, as yet undetermined.

According to yesterday’s Space News article, the contract for this flight had been signed prior to NASA establishing its new much higher prices for the use of ISS.

Launch of Intuitive Machine’s first lunar lander delayed

9:15 am

Capitalism in space: The first mission of Intuitive Machine’s lunar lander has now been delayed from late this year to early next year.

Intuitive Machines spokesman Josh Marshall said April 26 that the slip was caused by its launch provider. “SpaceX informed Intuitive Machines that due to unique mission requirements the earliest available flight opportunity is in the first quarter of 2022,” he told SpaceNews.

Marshall referred questions about the “unique mission requirements” that caused the delay to SpaceX. That company did not respond to questions from SpaceNews on the topic.

Though it is entirely possible that SpaceX needed to delay the launch, we should be skeptical of this reason. More likely Intuitive has had issues that caused a delay, and is using SpaceX as a cover.

There is a race to become the first privately-built commercial lunar lander. Astrobotics Peregrine lander is still scheduled to launch by the end of the year. We shall see.

SpaceX launches 60 more Starlink satellites; China launches Tianhe station module

10:16 pm

Twas a busy evening. SpaceX successfully put 60 more Starlink satellites into orbit using its Falcon 9 rocket, with the first stage successfully completing its seventh flight, landing safely on the drone ship in the Atlantic.

China in turn successfully used its Long March 5B rocket to place in orbit the core module, dubbed Tianhe, of its planned space station. This is the first of eleven launches in the next two years to assemble the station’s initial configuration, including cargo and manned missions along the way.

The SpaceX live stream is at the link. I have embedded China’s English language live stream of the Tianhe launch below the fold. The launch is about 52 minutes in.

SpaceX leases bigger space at LA port for processing Falcon 9 boosters after launch

9:03 am

Capitalism in space: According to the mayor of Los Angeles, SpaceX has signed a new lease for more space at the city’s port, taking over the facilities no longer used by Sea Launch’s floating launch platform that is now in Russia.

News of the port lease broke on April 26th with a tweet from the mayor of Long Beach, California after the Port of Long Beach (POLB) Commission voted to approve SpaceX’s 24-month sublease with an effective start date of May 1st, 2021. From 2014 to 2020, a massive floating rocket launch complex and associated service ships once used by SeaLaunch called POLB’s Pier 16 home while mothballed and the company left behind a decent amount of infrastructure when it vacated the facility last year.

That includes a ~5600 square meter (~65,000 sq ft) warehouse and office space formerly used to process SeaLaunch payloads and Ukrainian Zenit rockets, as well as a pier and dock space generally optimized for loading and unloading large rockets from rocket transport ships. In other words, Pier 16 is a perfect fit for SpaceX’s needs.

SpaceX has twice before signed similar leases and then canceled them. Now it appears the deal is more firm, as the company appears to be gearing up for regular Starlink satellite launches from Vandenberg, requiring a bigger need in LA for processing Falcon 9 first stage boosters after launch.

I wonder too if this deal might be in connection with Starship and the two used floating oil rigs that SpaceX now owns and is refitting as Superheavy/Starship launch and landing pads. This LA facility would be ideal for these ocean platforms before and after launch.

Weather delays next manned flight on Endeavour capsule one day

9:07 am

NASA and SpaceX have chosen to delay tomorrow’s second manned flight on SpaceX’s Endeavour capsule one day because of “unfavorable weather conditions forecast along the flight path for Thursday.”

The launch is now scheduled for 5:49 am (Eastern) on April 23rd. NASA of course will live stream it, though you will have to listen to a lot of pro-NASA propaganda, even though this flight is almost entirely run by SpaceX using a SpaceX rocket, a SpaceX capsule, and SpaceX launch and landing crews. NASA’s real involvement is as a very interested and involved customer during launch and recovery, and then in charge while the crew is docking or is on board ISS.

This will be the first time astronauts will fly on a reused SpaceX capsule. Endeavour was used for the first manned test flight last spring. That earlier flight also creates an interesting human interest side story on this flight. Of the four person crew, pilot Megan McArthur also happens to be the wife of Bob Behnken, who flew on Endeavour last year.

SpaceX’s Falcon Heavy wins launch contract for VIPER lunar rover

9:39 am

Capitalism in space: Astrobotic, the company building the lander to place NASA’s VIPER lunar rover on the Moon, has picked SpaceX’s Falcon Heavy as the rocket to launch the package.

This mission is part of a fleet of landers being sent to the Moon in the next two years, as part of NASA’s Commercial Lunar Payload Services (CLPS) program to hire private companies to do this rather than NASA.

Intuitive Machines, which won CLPS task orders for two lander missions, will launch each on Falcon 9 vehicles late this year and in 2022. Masten Space Systems selected SpaceX to provide launch services for its XL-1 lander mission, which won a CLPS award for a late 2022 mission.

Astrobotic will launch its first CLPS mission, a smaller lunar lander called Peregrine, on the inaugural launch of United Launch Alliance’s Vulcan Centaur currently scheduled for late this year. Firefly Aerospace, which won the most recent CLPS award in January, has not selected a launch provider yet for its Blue Ghost lander, but noted the lander is too large to launch on the company’s own Alpha rocket.

That’s five American lunar missions, all built and owned by private companies. Nor will these be the only unmanned lunar missions, when you include the UAE rover targeted for a ’22 launch, along with additional planned Indian, Chinese, and Russian missions. Almost all are aimed at the Moon’s south polar regions.

It is going to get both crowded and busy on the Moon in the next few years.

UAE hires Japanese company as partner for its ’22 lunar rover mission

9:34 am

Capitalism in space: The United Arab Emirates (UAE) has chosen the private Japanese company Ispace to provide the lander bringing its Rashid rover to the Moon in 2022.

ispace’s 240 kg lander is 2.3 meters tall and 2.6 meters wide. It will be launched by SpaceX, Elon Musk’s rocket company, on a Falcon 9 rocket. Once the iSpace lander is placed in the Earth’s orbit, it will travel to the moon on its own, land and unload the rover.

The lander will use solar panels for power, which will also allow the rover to communicate with Earth. It will also carry a solid-state battery made by NGK Spark Plug, which intends to examine its battery’s lunar performance.

This UAE project is similar but a step up from its Al-Amal Mars orbiter. In that case UAE used its money to have the orbiter mostly built by U.S. universities as they taught UAE’s students how to do it. In this case, UAE engineers appear to be building the rover itself, with the purchased help of others to provide the lander..

Falcon 9 upper stage debris lands on Washington farm

9:57 am

Falcon 9 helium pressure tank
Click for full image.

When a Falcon 9 upper stage broke up over the Pacific northwest last week apparently one of its interior helium pressure tanks, used to help push the fuel or oxidizer from the larger tank during launch, fell on a Washington farm and has since been recovered.

The image to the right is that tank, in what appears to be remarkable shape. From the article:

Composite-overwrapped pressure vessels, or COPVs, are standard components in Falcon 9 rockets. They’re designed to hold the helium gas that’s used to pressurize propellant tanks. COPVs are likely candidates to survive re-entry because they’re relatively lightweight and heat-resistant.

The tank has been returned to SpaceX, which I am sure is going to be very interested in studying its condition very thoroughly.

Last two passengers on 1st entirely private manned spaceflight revealed

9:17 am

Capitalism in space: The last two passengers for the first entirely private commercial manned spaceflight, dubbed Inspiration4 and paid for by businessman Jared Isaacman, were announced yesterday, along with a launch date no earlier than September 15, 2021.

Isaacman bought the mission partly to fly in space, but also to raise money for St. Judes Children’s Research Hospital. Both Isaacman and Haley Arceneaux, a former St. Judes cancer patient, will fly. Their two new crew members are both experienced in aviation or spaceflight operations, though neither is a professional astronaut with any training in that field.

[Sian] Proctor describes herself as a scientist turned artist and an “analog astronaut” where people live in environments to simulate long-duration spaceflight. She has done four analog missions including NASA’s Hawai’i Space Exploration Analog and Simulation (HI-SEAS) Habitat to simulate a trip to Mars. She is a pilot, scuba diver, “and loves geoexploring our world.” Born in Guam while her father was working at a NASA tracking station there during the Apollo program, she has a B.S. in environmental science, an M.S. in geology, and a Ph.D. in Curriculum and Instruction: Science Education. She was a finalist in NASA’s 2009 astronaut selection.

While a U.S. Space Camp counselor, [Chris] Sembroski conducted simulated space shuttle missions and supported STEM-based education. He served in the Air Force maintaining a fleet of Minuteman III ICBMs and served in Iraq. After leaving the Air Force in 2007, he earned a B.S. in Professional Aeronautics from Embry-Riddle Aeronautical University. He now works for the aerospace industry in Seattle, although he did not specify what company.

Their spacecraft will be Resilience, the Dragon capsule that flew the first operational manned commercial crew to ISS, and is presently docked to the station. For the Inspiration4 flight however SpaceX is going to install a large domed window at the capsule’s nose, replacing the docking port that will not be needed.

SpaceX successfully launches another 60 Starlink satellites

8:51 am

SpaceX early today successfully used its Falcon 9 rocket to place another 60 Starlink satellites into orbit, bringing that constellation to over 1,300 satellites.

The first stage landed successfully, for the sixth time. Both fairing halves were also reused, and their recovery method has now been simplified:

SpaceX has recently appeared to adjust its fairing recovery strategy. The ships previously dedicated to fairing catch attempts, GO Ms. Chief and GO Ms. Tree, have been stripped of their nets and arms, a possible sign that dry fairing recoveries will no longer be attempted. Post-splashdown recovery has proven to be fairly successful, as recent missions frequently use fairing halves that have flown once if not multiple times before.

SpaceX requests FCC permission to expand Starlink service to trucks, ships, & planes

9:44 am

Capitalism in space: SpaceX has submitted a request to the FCC to expand its Starlink customer base by providing the service not only to rural areas but to large moving vehicles, such as trucks, ships, & planes.

In its application to the FCC, filed on Friday, SpaceX said expanding Starlink availability to moving vehicles throughout the U.S. and to moving vessels and aircraft worldwide would serve the public interest. “The urgency to provide broadband service to unserved and underserved areas has never been clearer,” David Goldman, SpaceX’s director of satellite policy, said in the filing.

Goldman said SpaceX’s “Earth Stations in Motion,” or ESIMs, would be “electrically identical” versions of the $499 antenna systems that are already being sold to beta customers. He suggested that they’d be counted among the million end-user stations that have already been authorized by the FCC.

…SpaceX CEO Elon Musk said in a tweet that Starlink’s ESIM terminals would be “much too big” to mount on cars — such as the electric cars that are made by Tesla, the other company that Musk heads — but would be suitable for large trucks and RVs.

The article at the link notes in detail how this request poses a serious competitive threat to two of SpaceX’s biggest rivals, Klymeta and Amazon’s Kuiper constellation. This is true, but it is so mostly because SpaceX has already launched more than a thousand satellites in its constellation, and is simply taking advantage of its advanced position to undercut its rivals.

For example, though Klymeta might be using already orbiting satellites put up by different companies, it is also charging twice what SpaceX wants to charge for its antenna system, making Starlink a more attractive product. Amazon meanwhile appears years away from launching its first satellite. It might have a better design, but such things are worthless if they aren’t built and operational.

These companies have no one to blame but themselves if Starlink grabs their hope-for market share. And the FCC should not block SpaceX just to protect them.

Booster landing failure on Feb 15 Falcon 9 launch began with engine issue during lift-off

8:37 pm

SpaceX revealed today that the failure on February 15th of the 1st stage of the Falcon 9 rocket to land successfully first appeared during liftoff.

During a NASA press conference March 1 about the upcoming Crew-2 commercial crew flight, Benji Reed, senior director for human spaceflight programs at SpaceX, said that while the booster used on that Feb. 15 launch was making its sixth flight, some components on it were “life leaders” that had flown more often than any other in the Falcon 9 fleet. That included “boots,” or covers around parts of the Merlin engines in the first stage. “This was the highest count number of flights that this particular boot design had seen,” he said.

However, one of those boots had a “little bit of a hole” that allowed hot gas to get into parts of the engine during flight, he said. “A little bit of hot gas got to where it’s not supposed to be, and it caused that engine to shut down,” he said. Reed didn’t mention at what point in the launch the engine shut down, but he suggested it took place during ascent.

…The shutdown of the engine, though, kept the first stage from landing. “When that booster came to return home, because of the problem with that particular engine, we didn’t have enough thrust to get back to where we needed to be, and didn’t land where we wanted to be,” he said.

These facts help explain why SpaceX paused all its subsequent flights. An issue during liftoff is more serious than one that occurs during the return to Earth, as it suggests a problem that could impact future launches and the ability of the rocket to deliver its payload, its primary task.

SpaceX: No 1st stage footage on tonight’s Starlink launch

9:22 am

During last night’s short broadcast leading to the abort at T-1:24 seconds of a launch of another 60 Starlink satellites, the company announced that it would not show the video feed from the reused first stage booster as it returned to Earth.

[A] SpaceX engineer revealed that the company would not be broadcasting live feeds from Falcon 9 B1049’s onboard cameras during the launch. The ambiguity of the comment made it impossible to determine if SpaceX was simply choosing to not show those views or if something was wrong with the camera downlink system, while the same engineer-turned-host did go on to state that “all systems are green” moments later.

No explanation for the sudden change – possibly the first webcast in years without live views from booster cameras – was given. Starlink-17 serves as a return-to-flight mission for SpaceX after Starlink-19’s failed landing, during which the rocket’s onboard cameras streamed what appeared to be clearly unusual and possibly off-nominal behavior early on in the landing process.

The article at the link then speculates that maybe SpaceX was worried about that booster’s ability to land (it will be flying its eighth time, same as the booster that failed on the earlier flight).

I am very skeptical of that theory, especially because SpaceX has never shown a reluctance to show the public its failures. Instead, I think SpaceX has decided to do an engineering test of that booster during its return, and for propriety reasons wants to keep this from public eyes. If so, the test itself might also mean they are willing to lose this booster during that test.

During the early days of their program to reuse boosters, they sometimes had the returning 1st stage do some very stressful maneuvers, producing very spectacular light shows when launched from Vandenberg on the California coast. It could be they want to test this older booster on its eighth flight in a similar manner, in order to reassess their engineering and thus make it possible to upgrade and extend the re-usability of later boosters.
