Jeff Bezos sells $3 billion more in Amazon stock

9:23 am

Jeff Bezos this week sold another $3 billion in his Amazon stock, bringing the sales this year along to more than $7 billion.

Amazon stock has soared since mid-March as millions of customers rely on the e-commerce giant amid the pandemic for online shopping, cloud computing, and more. Last week the company posted $88.9 billion in revenue, up 40% from the year-ago quarter, with profits far ahead of Wall Street expectations at $5.2 billion.

Bezos said in 2017 that he was selling $1 billion a year to fund his Blue Origin space venture, but he has been increasing the size and frequency of the stock sales. He sold $2.8 billion worth of Amazon stock a year ago, and around $4 billion earlier this year.

Since 2017 Bezos has now raised more than $11 billion from sales of his Amazon stock. Initially he had said such sales were to finance his space company Blue Origin, but more recently he has indicated he wants to use the bulk of this cash to fight climate change, with portions also devoted services for the homeless and early childhood education.

In fact, it appears that Blue Origin is likely getting only a very small portion of this money, though at several billion this isn’t chicken-feed. At a minimum it likely matches what SpaceX has raised through private investment capital for its Starship/Starlink projects, and more likely exceeds it.

Yet, SpaceX continues to outpace Blue Origin, several times over. If anything, as the cash from Bezos has rolled in Blue Origin’s pace of test flights with New Shepard as well as the development of its BE-4 rocket engine and New Glenn orbital rocket seemed have slowed. Initially New Glenn was going to make its first orbital launch this year. Now they say it will launch next year but we hear little about any development progress. And the company only delivered a test engine of the BE-4 (not flight worthy) to ULA only about a month ago, far later than first promised.

Though the lack of news could simply be Blue Origin’s more secretive way of doing things, compared to SpaceX, I have my doubts. Rockets are big things, and building and testing them is not something easily kept under wraps, especially by private companies. The lack of news from Blue Origin continues to suggest that simply having lots of money does not necessarily guarantee success.

Fifth Starship prototype flies!

5:33 pm

Starship #5 in flight
Shortly after take-off.

Right after landing
Right after landing.

Shortly after landing
After the smoke has cleared.

Capitalism in space: SpaceX’s fifth Starship prototype today successfully completed a 150 meter hop at its Boca Chica facility in Texas, landing vertically.

I have embedded a video of the flight below the fold.

The screen capture to the right shows it in flight. It is canted slightly because its one Raptor engine was not centered at its base but offset.

The next image shows the prototype standing vertical on the ground to the left of Starhopper, which flew one year ago. All told the flight lasted only about a minute.

The final image shows a close-up of the prototype after the smoke has cleared. Why it is canted on the ground is not clear. Its legs are not visible (they apparently are relatively small), so it is hard to say whether one buckled or not.

The launch platform might have sustained damage but they have another ready to go. It is even conceivable that they could fly this prototype again, though they already have prototype #8 waiting in the wings.

Regardless, expect SpaceX to keep its fast development pace going. I would not be surprised if they attempt another test flight in less than two weeks.

Virgin Galactic again delays first commercial flight

9:12 am

Capitalism in space: Virgin Galactic, which has been repeatedly delaying its first commercial flight for more than a decade, has done so again, stating that it will not occur until 2021.

The company, in its fiscal second quarter financial results released Aug. 3, said it expected to perform two more test flights of SpaceShipTwo from Spaceport America in New Mexico, both of which will be powered flights. The vehicle has made two glide flights since moving to the spaceport early this year.

The first of those powered flights, scheduled for the fall, will have two pilots on board. It will also carry payloads for NASA’s Flight Opportunities program that arranges flights of experiments on suborbital vehicles, said George Whitesides, chief space officer and former chief executive of Virgin Galactic, in a company earnings call.

If that flight goes as expected, Virgin Galactic will then perform a second flight, this time with four mission specialists on board along with the two pilots. Those mission specialists “will evaluate the performance of our full customer cabin and associated hardware,” he said. The company unveiled the design of the cabin July 28, although Whitesides said they were still completing the installation of the cabin on the company’s current SpaceShipTwo vehicle, VSS Unity.

“Presuming things go as expected on this fully-crewed flight, we would then plan to fly Sir Richard Branson on the third powered flight from New Mexico,” he said. That flight would take place in the first quarter of 2021 and mark the beginning of commercial service, although Whitesides said it will also be a test flight of sorts. “Sir Richard is in a unique position to provide the ultimate cabin and spaceflight experience evaluation, as a visionary of the Virgin customer experience.”

The company also announced that it intends to sell stock shares to raise more capital. Right now the stock is selling for about $20.

I am no expert on the stock market, but to my mind this company’s chances of making big profits from suborbital flights is slim to none. They might make some money, but hardly enough ever to repay their investors. Virgin Galactic’s window for making big money in suborbital tourism closed forever with the success of SpaceX’s manned Dragon flight to ISS. The space tourism market is shifting to orbital space, something Virgin Galactic cannot provide. Worse, the cost for getting to orbit continues to drop, while this company can’t reduce its prices much.

Virgin Galactic provides a weak product in the present market, one that can only become weaker when compared to its competitors.

Starship hop today?

8:00 am

UPDATE: They are close to trying again. If you refresh your screen, you will now have two iterations of the live stream. This will allow you to have two cameras visible at the same time, You can show the main “nerdie” camera on one, with their commentary, and show the wider “sapphire” camera on the second. You pick cameras by clicking on the camera icon in the menu bar at the bottom of the screen.

UPDATE: First attempt apparently aborted. No word yet if they will attempt again today.

UPDATE: Scrubbed on August 3rd, attempting again on August 4th.

Capitalism in space: SpaceX’s Starship team has scheduled the first 500 foot hop of the fifth Starship prototype today, after canceling yesterday’s attempt.

The window for Starship SN5’s 150m hop debut now stretches from 8am to 8pm CDT (13:00-01:00 UTC) on Monday, August 3rd. It’s currently unknown if SpaceX will offer its own live coverage of the test flight but several unofficial streams will likely be available from NASASpaceflight.com, LabPadre, SPadre, and more. Stay tuned for updates!

I have embedded LabPadre’s live stream below the fold, if you wish to run it in the background. They will have commentary when they note a “pad clear” signal.

Private Japanese lunar lander redesigned, flight delayed one year

8:37 am

Capitalism in space: The privately financed Japanese lunar landing company Ispace has redesigned its lander and delayed the first flight by one year, to 2022.

Since a preliminary design review in 2018, ispace has reduced the size of Hakuto-R. Previously 3.5 meters high and 4.4 meters wide with its landing legs deployed, the lander is now 2.3 meters high and 2.6 meters wide. The spacecraft’s mass has decreased from 1,400 to 1,050 kilograms, primarily by reducing the amount of propellant on board.

A smaller lander is less expensive to develop, said Ryo Ujiie, manager of the lander system engineering group at ispace, during a call with reporters July 30. It also reduces the size and complexity of the landing legs. The spacecraft will use a different trajectory to go to the moon, employing a low-energy transfer orbit that requires less propellant but takes roughly twice as long as previously planned. “We had to pick a more propellant-efficient orbit” given the reduction in propellant, said Chit Hong Yam, manager of the mission design and operations group. “We’re confident that, with enough checking, we should be able to execute this orbit.”

While the overall lander is smaller, it still maintains a payload capacity of 30 kilograms. Once on the surface, likely at one of several mid-latitude sites on the moon under consideration by ispace, it will operate for 12 days.

That first flight will launch on a Falcon 9. The company raised $95 million in private capital in 2017, and still plans a second lander launch in 2023.

Endeavour safely splashes down

11:52 am

Splashdown of Endeavour

Capitalism in space: SpaceX’s Endeavour Dragon capsule has successfully splashed down in the Gulf of Mexico, returning two humans back to Earth safely after completing the first two month long manned commercial space mission.

If you go to the live stream to watch recovery operations, note that the boats and ships and persons involved are all property and employees of SpaceX. This is entirely an operation of the private company. The government is not involved, other than NASA’s justified monitoring as SpaceX’s customer.

One cool tidbit for the future. Endeavour is scheduled to fly again, in the spring of 2021. On that flight will be Megan McArthur, the wife of astronaut Bob Behnken, and she will likely sit in the same place he did on his flight.

Russians sign deal to fly two tourists to ISS

10:30 am

Capitalism in space: Now that their Soyuz capsule is no longer required to fly NASA astronauts to ISS, the Russians have spare seats, and have now signed a deal with Space Adventures to fly two tourists to ISS in late 2021.

They will announce the tourist’s names later this year.

Space Adventures also has a deal with SpaceX to fly two tourists on a Dragon capsule on a week-plus long orbital mission (not docking with ISS). SpaceX also has a deal with the space station company Axiom to fly tourists to ISS. Next year could thus see two or three tourist flights to space.

Isn’t competition wonderful?

Electrical disconnect caused Rocket Lab’s July 4th launch failure

6:21 pm

Capitalism in space: According to Rocket Lab’s investigation into the July 4th launch failure, an electric connection detached and cut off power to the upper stage, causing it to cease firing prematurely.

Once the electrical system disconnected in flight, it cut power from the rocket’s battery to the electric turbopumps on the Electron’s second stage Rutherford engine. That caused the engine to switch off prematurely around five-and-a-half minutes after the rocket took off from Rocket Lab’s launch base in New Zealand.

The early engine shutdown prevented the rocket from reaching the velocity necessary to enter a stable orbit around Earth, according to Peter Beck, founder and CEO of Rocket Lab, a small satellite launch company headquartered in Long Beach, California.

But telemetry continued streaming from the launch vehicle back to Rocket Lab’s control center in Auckland, New Zealand, allowing engineers to analyze data and determine the cause of the failure. The kerosene-fueled second stage engine shut down in a controlled manner, and the rocket coasted to an altitude of around 121 miles (195 kilometers) before re-entering the atmosphere and burning up.

Now that the company understands what caused the detachment, it will institute testing to make sure it doesn’t happen again. The fix however will not require any redesign of the rocket, and so they are targeting late August for their next launch, followed in September with the first launch from Wallops Island, Virginia. They also still expect to complete one launch per month through the end of the year.

Yutu-2 completes 20th lunar day on Moon

10:28 am

The new colonial movement: The Chinese lunar rover Yutu-2 has completed its 20th lunar day on the farside of the Moon, and has now been put in sleep mode for the long lunar night.

Yutu 2 continued on its planned journey to the northwest of the lander, according to the China Lunar Exploration Program (CLEP). The rover covered 90 feet (27.64 meters) during the lunar day to make a total of 1,610 feet (490.9 m) of roving since setting down on the far side of the moon in January 2019.

The article at the link includes some images, including visual data from the ground-piercing radar that suggests at least four layers in the lunar subsurface.

Manned Dragon return on August 2nd threatened by weather

4:08 pm

Capitalism in space: The splashdown of SpaceX’s first manned Dragon capsule Endeavour on August 2nd is now threatened by weather.

Isaias officially became a named tropical storm on Wednesday night, when its wind speeds exceeded 39 mph. The storm could affect several landing areas just as Endeavour is supposed to reenter Earth’s atmosphere, deploy its parachutes, and splash into the Atlantic Ocean or Gulf of Mexico.

Three of the seven landing zones that SpaceX and NASA prescribed for the test mission, called Demo-2, lie within the “cone of probability” for the storm’s path. Those splashdown sites are located off the coasts of Cape Canaveral, Daytona, and Jacksonville, according to NASA. A July 30 map shows NASA and SpaceX’s landing zones for the Crew Dragon Demo-2 mission amid the estimated path and conditions of Tropical Storm Isaias. The outer-edge green shows a 5-10% chance of sustained tropical storm-force winds. Google Earth; NOAA; NASA; Business Insider

Depending on how large the storm grows and how nasty weather conditions become, mission managers may scrub the undocking and landing attempt. Steep waves, rain, lightning, low clouds, poor visibility (for helicopters to fly the astronauts from a SpaceX recovery boat back to land), or even winds stronger than about 10 mph can trigger a “no-go” decision.

At the moment they are go for undocking on August 1st and splashdown the next day, but that could change depending on how the weather changes.

Midnight repost: Buy dumb!

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: The failures of modern technology (shaped sadly by a lot of government regulation) often illustrates well the coming dark age. Tonight’s repost from September 15, 2019 gives one good example, and what you can do to counter this trend.

——————————–
Buy dumb!

The dumb washing machine we hunted for and got
The used “dumb” machine we
paid $285 for that actually
cleans our clothes.

The smart washing machine we threw out
The “smart” machine that we
paid $923 for and sold for $40.

Two years ago our old Kenmore Series 80 washing machine broke down. The repair guy said it would be so expensive to fix that he recommended it was time to buy something new.

So off we went to Sears, where we ended up buying one of today’s modern “smart” machines for a mere $923. As the LG website proudly exclaims,

A Smarter Way to Wash: 6Motion™ Technology uses up to 6 different wash motions to provide a smart cleaning experience that is gentle on clothes and maximizes washing performance.

The problem was the machine never got any of our clothes clean. It also refused to provide enough water. The way it worked was to sense the weight of the clothes you put inside, and determine the needed amount based on this. Routinely, it wasn’t enough, so Diane did web searches to discover numerous owners faking out the machine’s brains by pouring several buckets of water on top of the clothes before turning on the machine, making them weigh more.

The machine also did not have an agitator, the new in-thing among washing machine manufacturers two years ago, probably forced on them by new federal regulations. And though the tub itself did shake, it did it so gently that the clothes hardly moved.

There were also other issues with the machine’s smart technology that frustrated Diane. The machine was boss, and would not allow for any flexibility to its predetermined wash and rinse cycles, even when they made no sense.

Last week Diane had had enough. » Read more

Northrop Grumman about to launch second mission extension robot

10:20 am

Capitalism in space: The success of Northrop Grumman’s first Mission Extension Vehicle (MEV-1) to dock with a dead communications satellite and bring it back to life has set the stage for the second MEV, set for launch on an Ariane 5 before the end of the month.

For MEV-1’s mission, Intelsat decommissioned the 901 satellite and moved it up into the GEO graveyard for rendezvous and docking operations.

However, the main result of the excellent performance of MEV-1 and a full demonstration of the docking and capture process is that MEV-2 will not be required to rendezvous with its target in the GEO graveyard. Nor will the satellite be deactivated. Instead, MEV-2 will move directly to the main operational GEO belt and approach Intelsat 10-02 while the satellite is still actively relaying telecommunications. “Intelsat has confirmed their desire on the next MEV, MEV-2, to do the docking directly in GEO orbit. They will be maintaining customer traffic as we do the docking with MEV-2,” noted Mr. Anderson.

This new approach, which was always the goal for future MEV operations, was aided in large part by confirmation to a high degree of accuracy that all of MEV’s systems worked as planned during Intelsat 901 operations.

The article notes that this concept could even be extended to sending a robot to Hubble to provide it accurate pointing capability when its last gyroscopes finally fail, thus extending the life of that space telescope even farther beyond its original planned fifteen year lifespan that ended in 2005.

SpaceX to raise another billion in private investment capital

11:16 am

Capitalism in space: SpaceX is now in the process of raising another billion dollars in private investment capital in order to fund both its Starlink and Starship projects.

Space Exploration Technologies, Elon Musk’s reusable rocket venture, is in talks to raise $1 billion in series N funding at a valuation of $44 billion, according to documents reviewed by CNBC. SpaceX plans to use the funding to make its Starlink satellite broadband service operational, and to conduct suborbital and orbital test flights of its Starship and SuperHeavy booster launch vehicle.

Up to now SpaceX has raised just under $2 billion in private capital, which they had said was devoted solely to developing Starship. The company had also said that it was developing Starlink with in-house funds. It appears that — having gotten almost 400 satellites in orbit (with many more coming) — they are now willing to seek outside help to make the Starlink system operational, because this situation allows SpaceX to negotiate the best deal with any investor.

It must also be emphasized that SpaceX is developing Starship/Super Heavy entirely from private funds, not government subsidies. This lack of government funds also means a lack of government oversight, which gives SpaceX complete freedom during development. Government oversight would only slow things down and likely prevent the company from innovating.

Instead, it is free to build the first completely reuseable rocket that also happens to be as powerful as a Saturn 5. And it will do it for less total than NASA has and will spend each year on SLS, for more than twenty years.

NASA’s safety panel expresses concerns about Starliner

11:02 am

My heart be still: During a teleconference yesterday, members of NASA’s safety panel expressed concerns about Boeing’s Starliner capsule while cautiously and very tentatively endorsing SpaceX’s intention to launch future manned missions with reused Falcon 9 first stages and reused Dragon capsules.

I consider this safety panel worse than useless. For example, based on this news report, they appear to have had little involvement in the NASA/Boeing investigation into the issues that caused the premature de-orbit of first unmanned orbital test flight of Starliner. Instead, it appears they have simply reviewed that investigation, and are now just kibbitzing from the sidelines.

Of course NASA should be concerned about the 80 issues it found, mostly involving software. No one needs this safety panel to tell the agency this.

Meanwhile, the panel’s tentative support for reusing Falcon 9 boosters and Dragon capsules is merely a rubberstamp of already decided NASA policy, and also illustrates the panel’s uselessness. This safety panel spent the last five years blasting everything SpaceX was doing (causing many delays), while literally missing the real elephant in the room, Boeing’s own quality control issues.

It appears to me that NASA is very gently and quietly making the safety panel irrelevant to its operations. Even better would be to disband it entirely. It serves no purpose other than to delay and block future exploration, sometimes foolishly.

Astra ships next rocket to Alaska for launch

10:43 am

Capitalism in space: The smallsat startup Astra has shipped its next test rocket to Kodiak, Alaska, for its planned six-day launch window, beginning on August 2nd.

The new two-stage launch vehicle, which the company calls Rocket 3.1, will take off from the Pacific Spaceport Complex on Kodiak Island. While the liquid-fueled rocket is designed to reach orbit, Astra says it will consider the test flight a success even it doesn’t enter orbit. “Success for this flight means we accomplish enough to make orbit within three flights, which we have defined as at least achieving a nominal first stage burn,” Astra said in June.

Chris Kemp, Astra’s co-founder and CEO, said the company will not be providing a live video stream of the launch to the public, but will release video imagery of the flight after it occurs. “We do not yet employ production, marketing, or communications folks, so our ability to produce a public webcast is limited,” Kemp said in response to questions from Spaceflight Now. “We are focusing all resources on engineering so that we can reach orbit in the next couple of flights.”

The August 2nd launch date is about two weeks later than they had announced in mid-June, but such a delay is not unreasonable for such a rocket test program.

They had attempted to launch an earlier rocket in March, only to have something go wrong during countdown.

Dragon update for the ongoing and next mission

10:34 am

Two stories today provide an update of the overall schedule and status of SpaceX’s manned Dragon capsule, both now and into the future.

First, they are preparing for the return of Bob Behnken and Doug Hurley from ISS on August 2nd. Prior to return they will use the station’s robot arm to inspect the capsule’s heat shield to make sure it did not sustain any damage during its two months in space. Such inspections will be standard procedure on future flights, something NASA did not do on shuttle flights until after the Columbia failure.

It is unlikely there is any damage, but making this inspection is plain common sense. If the heat shield has been damaged, the astronauts can stay on board ISS until the next Dragon arrives, which can then bring them home.

Second, NASA and SpaceX have worked out a tentative schedule for that next Dragon manned launch, now set for sometime in late September. The agency wants a bit of time to review the full results of the first demo mission before flying a second.

Based on all that has happened so far, it now appears unlikely that the agency will find anything that prevents that late September flight.

Break in fuel line caused LauncherOne failure

9:50 am

Capitalism in space: Virgin Orbit has determined that a break in the oxygen feed line in its LauncherOne rocket caused the failure during its first orbital test flight in late May.

Speaking at a webinar organized by the Space Generation Advisory Council, an organization for young space industry professionals, Dan Hart said the demonstration mission for the LauncherOne rocket May 25 went well until several seconds after the ignition of the NewtonThree engine that powers the rocket’s first stage. “We had a component break in our engine system. It was a high-pressure feed line,” he said. Liquid oxygen “stopped going into the engine and our flight was terminated.”

The company has performed an investigation and identified what needs to be fixed in the engine to strengthen the components that failed. A second LauncherOne rocket is in final integration right now and will be leaving the factory in the next few weeks while modifications to the engine continue. “We’ll be targeting our next flight before the end of the year,” Hart said.

They need to meet that schedule, as in the past few years they have consistently failed to fly when promised.

Cubesat uses thruster to avoid collision

9:42 am

Capitalism in space: For the first time a cubesat has used a thruster to not only adjust its orbit but to also avoid a collision with another satellite.

From June 23 to July 3, the UWE-4 cubesat fired its NanoFEEP thrusters several times to reduce its altitude by more than 100 meters. By comparison, natural orbital decay would lower the altitude 21 meters in the same timeframe, according to a University of Wuerzburg news release.

One July 2, as the UWE-4 cubesat was lowering its altitude, the University received a warning from the U.S. Air Force’s 18th Space Control Squadron of a July 5 conjunction with a retired Iridium satellite. When UWE-4 mission operations personnel analyzed the conjunction, they determined the UWE-4 cubesat would not collide with the Iridium satellite because it would be orbiting at a lower altitude. As a result of the analysis, UWE-4 mission operations personnel continued firing thrusters to lower the cubesat’s altitude. They received no further conjunction messages.

The thrusters were built by Morpheus Space. Incorporating thrusters onto a cubesat, the size of which fits on the palm of your hand, is quite amazing, and illustrates the growing capability of these tiny satellites.

Midnight repost: Elon Musk and the forgotten word

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: Today’s repost comes from October 20, 2011, following Elon Musk’s National Press Club speech where he announced he was going to vertically land the Falcon 9 first stages so they could be reused. In comparing the new commercial competitive space industry with NASA’s government-run space program, I tried to outline the fundamental reason the former was always going to do better than the latter.

———————————————–
Elon Musk and the forgotten word

Elon Musk at National Press Club

When Elon Musk gave his speech at the National Press Club on September 29, he was asked one question to which he really did not know the answer. He faked it, but his response illustrated how completely forgotten is one fundamental fact about American society — even though this fact is the very reason the United States became the world’s most wealthy and powerful nation less than two centuries after its founding.

To explain this fundamental fact I think I need to take a step back and talk about the ongoing war taking place right now over how the United States should get its astronauts into space. On one side we have NASA and Congress, who want NASA to build a new heavy-lift rocket to carry its Orion capsule beyond Earth orbit. On the other side we have a host of independent new space companies, all vying for the chance to launch humans and cargo into space for fun and profit.

Which is right? What system should the United State choose?

After releasing its Ryugu samples Hayabusa-2’s mission will continue

8:33 am

Japan’s space agency JAXA has revealed that it is looking at two fast-spinning asteroids as possible destinations for its Hayabusa-2 spacecraft after it has dropped off its samples from the asteroid Ryugu on December 6.

The candidate asteroids on the agency’s list are asteroid 2001AV43 which Hayabusa2 would reach in November 2029 after flying by Venus, and asteroid 1998KY26 which the probe would reach in July 2031 after passing by another asteroid.

JAXA says both asteroids are rotating on their axis once every 10 minutes. The high-speed spinning indicates that the asteroids’ inner structures are likely different from that of asteroid Ryugu on the first mission, which consists of pieces of rocks.

The spacecraft will no longer have the equipment for returning additional samples, but everything else is functioning and it has the fuel.

Tianwen-1 launch set for July 23rd

3:09 pm

China has rolled out its Long March 5 rocket and is now preparing to launch its Tianwen-1 orbiter/lander/rover to Mars this coming Thursday, July 23rd, some time between 12 am and 3 am (Eastern).

A Long March 5 rocket is set for liftoff with China’s Tianwen 1 mission some time between 12 a.m. and 3 a.m. EDT (0400-0700 GMT) Thursday, according to public notices warning ships to steer clear of downrange drop zones along the launcher’s flight path.

Chinese officials have not officially publicized the launch date. Chinese state media outlets have only reported the launch is scheduled for late July or early August, and officials have not confirmed whether the launch will be broadcast live on state television.

This will be the first operational launch of the Long March 5, which has had three previous test launches, with the first two failing. The success of the December launch, as well as the May success of the related Long March 5B, made this Mars mission possible.

After achieving orbit in February 2021 and spending two months scouting the landing site, the lander will descend to the surface, bringing the rover with it. The prime landing site is Utopia Planitia, in the northern lowland plains.
