Capitalism in space: SpaceX engineers yesterday performed static fire tests of both its Superheavy prototype #7 and its Starship prototype #24.

The Superheavy prototype fired one engine, and did so only a few weeks after that prototype experienced an explosive event the launchpad during earlier fueling/engine tests. Yesterday’s engine test was the first time any Superheavy prototype had fired its engines on the launchpad.

The Starship prototype meanwhile fired two engines on a nearby vertical test stand.

SpaceX’s plan is to stack #24 on top of #7 and attempt an orbital launch test that will have the Superheavy prototype land in the Gulf of Mexico while the Starship prototype reaches orbit and then returns to Earth in the Pacific northeast of Hawaii. Based on the company’s normal pace of operations, that flight is probably only weeks away. However, before that flight engineers will have to do a full static fire test of all 33 of #7 engines, and then like do it again with Starship #24 stacked on top.

Rocket Lab considering further targets for in-space Photon upper stage

12:12 pm

Capitalism in space: As noted during a speech yesterday by CEO Peter Beck, Rocket Lab is considering further interplanetary targets for its still functioning Photon upper stage, that helped launch NASA’s CAPSTONE mission toward the Moon.

Rocket Lab is continuing to operate Lunar Photon more than a month after it deployed CAPSTONE. The spacecraft is currently about 1.3 million kilometers from Earth, he said, and will swing back to Earth later in the month.

The spacecraft still has 10-15% of its propellant remaining. “As it scoots past Earth,” Beck said, “we’ll have a crack at doing something cool with it and see how far into the solar system we can get with it.”

Rocket Lab hopes to use a future Photon stage to send a probe to Venus, and is using the Photon in space now for engineering tests. It is also selling this technology as a viable cheaper alternative to the typically expensive interplanetary probes.

Debris from Russian anti-sat test causing numerous near Starlink collisions

12:04 pm

According to an official of a company that helps track space junk, the scattered debris from the satellite destroyed by Russia in an anti-satellite test in 2021 has had numerous near collisions with multiple Starlink satellites.

In the Aug. 6 event, Oltrogge said there were more than 6,000 close approaches, defined as being within 10 kilometers, involving 841 Starlink satellites, about 30% of the constellation. It’s unclear how many, if any, of the satellites had to maneuver to avoid collisions.

This conjunction squall was exacerbated by a new group of Starlink satellites. SpaceX launched the first set of “Group 3” Starlink satellites July 10 from Vandenberg Space Force Base into polar orbit, followed by a second set July 22. A third batch of Group 3 satellites is scheduled to launch Aug. 12.

The problem is only going to get worse, as this junk will be in orbit for quite some time.

Northrop Grumman partners with Firefly to make Antares entirely U.S. made

9:00 am

Capitalism in space: Because the Russian invasion of the Ukraine, Northrop Grumman yesterday announced that it has signed a deal with the rocket startup Firefly to replace the Russian engines and Ukrainian-built first stages on its Antares rocket.

Firefly’s propulsion technology utilizes the same propellants as the current Antares rocket, which minimizes launch site upgrades. The Antares 330 will utilize seven of Firefly’s Miranda engines and leverage its composites technology for the first stage structures and tanks, while Northrop Grumman provides its proven avionics and software, upper-stage structures and Castor 30XL motor, as well as proven vehicle integration and launch pad operations. This new stage will also significantly increase Antares mass to orbit capability.

The press release made no mention of launch dates. However, according to Reuters Northrop Grumman has purchased three SpaceX Falcon 9 launches in ’23 and ’24 to get its Cygnus cargo freighter into orbit in the interim and thus fulfill its ISS resupply contract with NASA.

After an earlier Antares failure the company (then Orbital ATK) had hired ULA’s Atlas-5 to launch Cygnus. ULA however is retiring the Atlas-5 after it completes its present full manifest, so this rocket was no longer available. ULA is replacing it with the Vulcan rocket, but that rocket is not yet operational due to delays in the delivery of its Blue Origin first stage engines. Thus, SpaceX was Northrop Grumman’s only viable option.

There is also a certain irony in the hiring of Firefly to replace the Ukrainian first stage. Firefly was saved from bankruptcy by a Ukrainian billionaire, Max Polykov. Though he has been forced to sell off his ownership in the company by the State Department, Firefly would not now exist to take this business from a Ukrainian company had Polykov not provided his financial help.

Russia and China complete launches

8:45 am

Both Russia and a pseudo-commercial Chinese company today completed launches.

Russia used its Soyuz-2 rocket to launch a military reconnaissance satellite for Iran, along with 16 Russian smallsats. The rocket was originally going to launch a South Korean satellite, but that launch was cancelled due to Russia’s invasion of the Ukraine.

In China, the pseudo-company Galactic Energy used its four-stage Ceres-1 rocket to place three Earth observations satellites into orbit. Because three of the rocket’s four stages use solid rocket motors, they were likely reworked from military applications. Thus, Galactic Energy does nothing without the full approval and supervision of the Chinese government. It might have been funded privately, and focused on making profits, but it really owns nothing it builds.

Nonetheless, this was its third successful orbital launch, making it the most successful of these Chinese pseudo-companies. It is also developing a Falcon 9 clone rocket dubbed Pallas-1, which it hopes to launch next year.

The leaders in the 2022 launch race:

34 SpaceX
29 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 49 to 29 in the national rankings, and the entire world combined 49 to 47. A SpaceX Falcon 9 launch later today should strengthen this lead again.

India’s new SSLV rocket fails on first launch attempt

10:53 am

Delayed years because of India’s panic over the Wuhan flu, the first launch of that country’s new Small Satellite Launch Vehicle (SSLV) failed today when the rocket’s fourth stage apparently did not fire its engines properly.

The problem appeared to be the SSLV’s terminal stage, called the velocity trimming module (VTM). According to the launch profile, the VTM was supposed to have burnt for 20 seconds at 653 seconds after launch. However, it burnt for only 0.1 seconds, denying the rocket of the requisite altitude boost. Two satellites onboard the rocket – the primary EOS-2 Earth-observing satellite and the secondary AzaadiSAT student satellite – separated from the vehicle after the VTM burnt.

As a result, the two satellites were put in an orbit that was too low, which quickly decayed, destroying both.

Since this launch failed, I do not count it in the launch totals for 2022.

Considering that this was SSLV’s first launch, it was in that sense a test, and a failure therefore is not unexpected. India’s real problem is that the launch was delayed so long because of the Wuhan panic, thus allowing other competitors to catch up and pass India. While it is certain ISRO will try again, and eventually succeed, it will not get the market share it would have had, had it launched in 2020 as originally planned.

SpaceX raises another $250 million in investment capital

8:58 am

Capitalism in space: SpaceX in July raised $250 million in investment capital from five unnamed investors, bringing the total raised in 2022 to $2 billion.

Added to the amount brought in before this year, SpaceX has raised about $9 billion in private capital, most of which is focused on financing the development of Starship/Superheavy. When you add the $2.9 billion contract it won from NASA to develop Starship as a manned lunar lander, the company has raised about $12 billion to build this heavy lift rocket.

The numbers demonstrate several things. First, Wall Street is apparently very confident SpaceX will succeed in building the rocket, and then make a lot of money from it. Second, the numbers prove it shouldn’t cost $60 billion and two decades to design and build a heavy lift rocket, as NASA has done with its SLS rocket. SpaceX is doing it for less than a fifth of the cost, in a third of the time.

Virgin Galactic once again delays commercial suborbital operations

9:08 am

Capitalism in space: In releasing its quarterly report, Virgin Galactic yesterday revealed that it is once again delaying the start of commercial suborbital operations, pushing back from the first quarter of 2023 to the second quarter.

In an earnings call, company executives said that the latest delay was not directly related to supply chain and staffing problems it blamed for the previous delay. Instead, refurbishment work on its WhiteKnightTwo plane, VMS Eve, was taking longer than planned. “The driver is around the amount of time it is taking us to accomplish the work scope on Eve,” said Michael Colglazier, chief executive of Virgin Galactic. “We did not plan the full amount of time that’s been needed to get this work accomplished.”

Company officials also said they are shifting its customer emphasis, now focusing much more on “private and government researchers.” Let me translate: The public is not buying tickets, so Virgin Galactic hopes to convince the government to keep it afloat instead.

I predict this company will likely never fly any customers, and it appears the stock agrees, with the stock plunging in value, from $8.25 to $6.95 in less than a day.

Astra cancels all launches with its Rocket 3.3 rocket

9:01 am

Capitalism in space: Astra yesterday announced that it has canceled all further launches with its Rocket-3.3 rocket, and will instead focus on developing a larger version, dubbed Rocket-4, which it says will begin test flights in 2023.

The company says that it will no longer fly the Rocket 3.3 and move on to its larger Rocket 4 vehicle that it announced in May. One change is that the payload performance of the new rocket has doubled to 600 kilograms. Kemp didn’t disclose details of the design change other than an upgrade to its upper stage engine. Rocket 3.3, by contrast, had a payload capacity of no more than 50 kilograms.

“The feedback that we were getting from some of the larger constellation operators was that satellites were getting larger,” he said. Discontinuing the existing Rocket 3.3, he said, allowed the company to focus its resources on the new launch system, including increasing its payload capacity.

Essentially, Astra has left the field and is at present no longer an operational smallsat rocket company. It is also likely that its announced schedule for its upgraded rocket will not be met. Thus, expect customers to shift to other launch providers able to launch satellites, such as Rocket Lab and Virgin Orbit.

Not surprisingly, the company’s stock plunged soon after this announcement.

SpaceX launches South Korea’s Danuri lunar orbiter

4:50 pm

SpaceX today successfully launched South Korea’s Danuri lunar orbiter, also called the Korea Pathfinder Lunar Orbiter.

The first stage completed its sixth flight, landing on a drone ship in the Atlantic. The fairings completed their fourth flight.

Danuri is now on its way to the Moon, with a planned arrival in lunar orbit on December 16, 2022. It carries six instruments, one of which was developed by NASA. The spacecraft, while designed to study the Moon, is primarily a technology test mission laying the groundwork for more sophisticated interplanetary South Korean missions. More information about the mission can be found here.

China launches “reusable experimental spacecraft”

4:02 pm

According to the official Chinese press, China today successfully used its Long March 2F rocket to place into orbit a “reusable experimental spacecraft.”

To say the information provided was terse is to be extravagant. This is it:

After a period of in-orbit operation, the spacecraft will return to its scheduled landing site in China. It will test reusable technologies and in-orbit service technologies as planned during its flight, providing technological support for the peaceful use of space.

It appears, based on the size of the rocket, that this spacecraft is likely a copy of Boeing’s X-37B.

The leaders in the 2022 launch race:

33 SpaceX
28 China
10 Russia
6 Rocket Lab
5 ULA

The U.S. still leads China 48 to 28 in the national rankings, and the entire world combined 48 to 45.

These numbers should change within the next half hour, as SpaceX is about to launch another rocket.

Axiom signs deal with New Zealand

9:52 am

Capitalism in space: The private space station company Axiom has now signed a deal with New Zealand to permit its citizens to propose and fly experiments on future Axiom missions, both to ISS and to Axiom’s own space station, scheduled for launch beginning in ’24.

This is the fourth international commercial agreement Axiom has signed since May, with Italy, Hungary, and the UAE the signatories in the previous deals. The UAE deal also included the launch of a UAE astronaut to ISS for a six month flight.

Axiom hopes to launch its first module to ISS in ’24, with later modules eventually allowing it to undock its section to fly as an independent station when ISS is retired.

Environmentalists opposed to Starship at Boca Chica appeal dismissal of their lawsuit

9:45 am

Environmentalists from the Sierra Club and one Texas Indian tribe have now appealed the dismissal of their lawsuit aimed at blocking further tests or launches of Starship and Superheavy by SpaceX at its Boca Chica facility.

The Sierra Club and the Carrizo/Comecrudo Tribe of South Texas jointly appealed the 445th District Court’s decision July 7 to dismiss a lawsuit concerning SpaceX testing of its next-generation Starship vehicle closing nearby Boca Chica Beach, the coalition said July 28. In the dismissal, Judge Gloria Rincones argued there is “no private right of enforcement” concerning the beach access, according to KRGV.com (opens in new tab). The dismissal took place over the appellants’ protests that closing the beach violates the Texas state constitution, along with access rights by traditional groups.

The Sierra Club’s Brownsville organizer, Emma Guevara, stated the appeal is taking place because the beach is closed weekly to allow “a billionaire [to] launch deadly rockets near homes and wildlife.”

Citing a fireball that briefly and unexpectedly engulfed Starship during testing July 12, Guevera said her family was “forced” to hear the noise, which “launched without any warning for the public.” [emphasis mine]

My my, what a horror! I suppose everyone must stop what they are doing because Guevera and his family might be inconvenienced. And who cares if the lawsuit prevents thousands of south Texas citizens from having jobs and a thriving economy? It is more important Guevera doesn’t have to hear loud noises.

The lawsuit claims that allowing SpaceX to periodically close access to the nearest beach violates the state’s constitution, despite laws passed by both the local and state legislatures allowing for these closures.

Next private SpaceX manned targeting December launch

9:31 am

Capitalism in space: SpaceX is now planning to launch in December the next private manned Dragon orbital mission, dubbed Polaris Dawn, and led by billionaire Jared Isaacman, who led the previous private Inspiration4 mission in September 2021.

Polaris Dawn is the first of three separate crewed launches, all of them funded by Isaacman. This first effort will see Isaacman flying a SpaceX Dragon spacecraft alongside Sarah Gillis, Anna Menon and Scott Poteet. (Both Gillis and Menon work at SpaceX.) The second launch aims to use a Dragon while the third is scheduled as the first crewed mission for Starship, SpaceX’s next-generation spacecraft.

…Among the mission’s aims is the first spacewalk, or extravehicular activity (EVA), of a private astronaut. The crew will use SpaceX-developed EVA suits for the effort. Crew Dragon will be depressurized for the spacewalk in a similar way that NASA’s Gemini capsules were in the 1960s, requiring all crew members to wear suits designed for a vacuum environment.

By not flying to ISS, Isaacman and SpaceX avoid the high fees NASA charges as well as its extensive requirements.

By remaining in orbit however the length of the mission will be limited to only a few days, rather than weeks. Thus, it underlines the growing need for private commercial space stations, not controlled by the government.

Rocket Lab launches second NRO surveillance smallsat in three weeks

10:14 pm

Capitalism in space: Rocket Lab today successfully used its Electron rocket to place its second National Reconnaissance Office (NRO) surveillance smallsat into orbit in just over three weeks.

For Rocket Lab, this was the sixth launch in 2022, which matches its previous annual high, achieved in both 2019 and 2020. It should easily top that record before the year is out.

The leaders in the 2022 launch race:

33 SpaceX
26 China
10 Russia
6 Rocket Lab
4 ULA

American private enterprise now leads China 47 to 26 in the national rankings, and the entire world combined 47 to 42.

Two more American launches are scheduled in the next day. If both are successful, the U.S. will have exceeded its entire launch total for 2021 (48) in only a little more than a half year, and completed the most successful launches since 1967.

The second half of the year should actually be as active as the first half, with three more American smallsat rocket companies (Firefly, Relativity, and ABL) pushing hard for their first successful launches before the year is out, thus joining the already operational smallsat rocket companies Rocket Lab, Virgin Orbit, and Astra.

NASA imposes new rules for any private launches to ISS

11:08 am

NASA has added several new rules for any private launches to ISS, now requiring that each flight include at least one experienced former NASA astronaut.

From the actual procurement notice:

NASA is also in the process of finalizing details associated with a new requirement that upcoming private astronaut missions include a former flown NASA (U.S.) government astronaut as the mission commander. A former NASA astronaut provides experienced guidance for the private astronauts during pre-flight preparation through mission execution. Based on their past on-orbit and NASA experience, the PAM commander provides a link between the resident ISS expedition crew and the private astronauts and reduces risk to ISS operations and PAM/ISS safety. Specific details of the requirement will be documented in future solicitations, as well as in updated documentation and in the solicitation technical library.

The new rules also require the companies to submit their research plans twelve months before launch, as well as reserve a longer time for the private passengers to adapt to weightlessness on the station before initiating that work.

The changes appear to make sense, based on the experience of the first passenger flight of Axiom sent up to ISS earlier this year. However, their existence will likely encourage the arrival of the private space stations in order to break free from NASA’s rules.

Momentus has now deployed seven of ten customer payloads from its Vigoride tug

10:59 am

Capitalism in space: Despite technical communications issues after deployment of the first test flight of its Vigoride orbital tug, Momentus yesterday announced that has now deployed seven of ten customer payloads.

This announcement is somewhat of a surprise, as in June the company had said it would not be able to deploy anymore payloads due to the communications and solar panel problems Vigoride was experiencing.

The update also noted that the company is incorporating changes in its next Vigoride tug, scheduled to launch in November.

Australian Space Agency confirms debris is from SpaceX Dragon capsule

10:28 am

Officials from the Australian Space Agency have inspected and confirmed that the debris that landed recently in the southeast Australia came from service module/trunk of a SpaceX Dragon capsule.

The agency had been alerted by Brad Tucker, an astrophysicist from the Australian National University, who first realised the timing and location of the debris falling coincided with a SpaceX spacecraft which re-entered the Earth’s atmosphere at 7am on 9 July, 20 months after its launch in November 2020.

Tucker believes the debris came from the unpressurised trunk of the SpaceX capsule, which is critical to take off but dumped when returning to earth.

This capsule was Resilience, launched on November 15, 2020 on SpaceX’s second manned launch for NASA. The capsule and crew returned in April, 2021. The service module apparently remained in orbit until July 2022, when its orbit decayed.

This service module was considered small enough it would burn up in the atmosphere. That assumption was apparently wrong. Though the pieces caused no damage, SpaceX needs to revise its operations to make sure future service modules will come back over the ocean, just in case sections reach the surface.

Flying car gets approved by FAA

9:27 am

Samson Switchblade

A small airplane that quickly converts to a three-wheel car has now been approved for airworthiness by the FAA, paving the way for the first flight tests.

After 14 years of development, the Samson Switchblade – a fast, street-legal three-wheeler that converts at the touch of a button into a 200-mph (322-km/h) airplane – has been approved for airworthiness by the FAA. The team is now preparing for flight tests.

The Switchblade is named after the knife-like way its wings swing out from beneath its two-seat cabin when it’s time to fly. The tail, too, swings out from where it’s stowed behind the large pusher prop, then unfolds into a generous T shape. Samson says the entire push-button conversion from street-legal trike to aircraft takes less than three minutes, and while it’s yet to demonstrate the entire process on a physical prototype, it looks like it’ll be a pretty spectacular process.

The goal is to create something you can drive from your garage to the nearest small runway, take off to fly to another nearby airport, and then quickly drive to your destination, without ever having to get out of your seat.

More information can be found at the company’s website, which also says it is “only months away from first flight”, and expects to sell its first kits for customers 18 months later. The company also says it has 1,500 customers who have already placed reservations to buy it.

Long March 5B pieces crash near villages in Malaysia and Indonesia

8:56 am

Several days after the July 30th uncontrolled de-orbit of China’s Long March 5B core stage locals in both Malaysia and Indonesia are finding large sections, some of which apparently fell close to villages.

A charred ring of metal about five metres in diameter was found on Sunday in Kalimantan, Indonesia, according to a Malaysian news outlet. Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, said the metal appeared to be the exact size of the Chinese rocket’s core stage.

…“It looks like the end cap of a rocket stage propellant tank,” he said. “There’s no doubt in my mind that it’s from the rocket … it’s in the right place at the right time and looks like it is from the right kind of rocket.”

The article at the link also describes several other incidences, including one in which two families were evacuated when a piece landed near their home. I have embedded the video of one news report below, showing several of these impacts, many of which which apparently hit the ground hard enough to create craters several feet deep.

The article contains a big error, stating “there was no international law” forbidding the uncontrolled crash of such debris, but this is false. The Outer Space Treaty requires all nations to take action to avoid such incidents, and makes them liable to any damage. China is violating this treaty with every Long March 5B launch.

Russia launches military satellite

8:45 am

Russia yesterday used its Soyuz-2 rocket to launch a military satellite believed intended as an “inspector” satellite, designed to get close to and track another American military reconnaissance satellite.

While no details about this payload are known, there is a suspicion that this payload might have been launched to match the trajectory and flight path of an American satellite, USA-326. This was launched by a SpaceX Falcon 9 last February on the NROL-87 mission and went into a 512 km altitude, 97.4° inclination orbit. It is speculated to be an experimental optical reconnaissance satellite.

The launch comes after a new object was tracked just a week ago from the USA 326 spy satellite. It was designated object 53315 and cataloged in a 348 x 388 km orbit.

…The USA-326 satellite phased over the launch site just as the Soyuz-2.1v rocket launched. This also matches the northerly direction NOTAM that was announced before the Soyuz launch. What is possible is that the Kosmos-2558 payload is an inspector satellite that will be used to monitor the appearance and behavior of USA-326 and/or object 53315.

The Soyuz-2 rocket itself was a rarely used variation of this rocket, using no side boosters.

The leaders in the 2022 launch race:

33 SpaceX
26 China
10 Russia
5 Rocket Lab
4 ULA

Rocket Lab tried three times yesterday to also launch, but high winds eventually forced it to scrub the launch, rescheduling for tomorrow.

American private enterprise still leads China 46 to 26 in the national rankings, and the entire globe combined 46 to 43.

China’s Tiangong-3 space station, as seen from the ground

9:37 am

Tiangong-3 in orbit on July 29, 2022

The screen capture to the right was taken by a very short ground-based telescopic movie of China’s Tiangong-3 space station on July 29, 2022. I have labeled it to indicate the various parts of the station, including the new large module, Wentian, that launched to the station on July 24, 2022.

In my original post, I had mislabeled the sections. I have now corrected the image. Thanks to reader Jay for pointing out my error.

Tianhe is the original core module of the station. At present Wentian is in the forward port, so that it and Tianhe lie in a straight line. At some point shortly before the October launch of the next module, Mengtian, they will likely move it 90 degrees to its permanent port to one side, so that Mengtian can dock with the front port where Wentian now sits.

Mengtian will then be shifted 90 degrees to its permanent port on the opposite side of Wentian. At that point the station will form its planned final T-shape configuration.

This dance of spacecraft is necessary to keep the station as balanced as possible to aid in attitude control.

Long March 5B stage falls to Earth near Malaysia

12:04 pm

New data now suggests that the core stage of China’s Long March 5B rocket that it launched on July 24th has crashed to Earth somewhere off the coast of the island of Borneo, Malaysia.

As of writing, there is no indication that any debris hit land, though this could change.

In violation of the Outer Space Treaty, China very clearly has done nothing to upgrade the Long March 5B since it dumped a core stage uncontrolled last year. It very clearly can do nothing to prevent this from happening in October, when the Long March 5B lifts off again to carry into orbit the last planned module for the Tiangong station.

In other words, China cannot be relied upon to honor any treaty it signs. It signs the treaty, but then willfully ignores it if it thinks that is to its best interest.

Space junk thought to be service module of Dragon manned capsule found in Australia

9:17 am

In news that is related to the impending crash of the Long March 5B core stage, Australian farmers have found scattered space junk pieces that some are claiming are the remains of the service module or trunk section that re-entered on May 5th, the day of the splashdown of SpaceX’s Endurance manned spacecraft.

The debris is most likely the unpressurized “trunk” of the spacecraft, astrophysicist Brad Tucker told Space.com. “Having gone out there and looked at the bits myself, there is not a doubt in my mind it is space junk,” he said in an e-mail. The trunk is designed to send unpressurized cargo into space, and also to support the Crew Dragon during its launch, according to SpaceX (opens in new tab). Half of the trunk includes solar panels that power Dragon when the vessel is in flight or docked to the station. The trunk detaches from the spacecraft shortly before re-entry.

The sonic boom, Tucker said, was widely heard at 7:05 a.m. local time on July 9 and the pieces found near Dalgety were “very close to the tracked path of the SpaceX-1 Crew trunk.”

The problem with this claim is that the sonic boom on July 9th matches no SpaceX launch or re-entry. The material however could be from that Endurance capsule, which returned May 5th, if the trunk once detached did not re-enter until two months later.

If confirmed, this story is surprising, as that service module is thought to be too small to survive re-entry through the atmosphere. It is instead expected to burn up before reaching the ground.

Long March 5B stage reentry window narrowed to two hours

8:50 am

Long March 5B impact prediction

The Aerospace Corporation has now narrowed the window in which the out-of-control core stage of China’s Long March 5B rocket will crash back to Earth to about two hours, centered over the Pacific west of the United States at in the early morning of July 31st.

China appears to have dodged a bullet once again. The window is now only a little more than one orbit long, so we now know the impact point for the five to nine tons that will survive re-entry is mostly over water.
