Why Google blurs surface images of Israel, and why that blurring could end

Link here. A 1997 U.S. law requires that all satellite imagery of Israel, Gaza, and the West Bank be blurred. The law also sets the resolution standard based on the best images produced by other commercial companies outside the U.S.

NOAA is now reviewing the law, since high resolution European commercial images have been available since 2012. If it decides this is the new standard, high resolution views of this very politically hot region could become publicly available for free.

The article focuses on the wonderfully good things in science and research this change would bring. It completely ignores the use that terrorist organizations, set on killing as many Israelis as possible, could put to such images.

In general, I prefer freedom and the wide distribution of information. In this case I am torn.

Interorbital successfully test flies its upper-stage engine

Capitalism in space: The smallsat rocket company Interorbital Systems successfully test flew the upper-stage engine for its rocket last week.

Video of the test below the fold. This company had appeared to be moving towards test flights in 2014, than nothing seemed to happen until earlier this year. The four year gap made me suspect they were in trouble. It now appears they are moving forward towards their first flight, though when that will happen remains unclear.

China launches two satellites on Long March 2C

China today launched two satellites for Pakistan using its Long March 2C rocket.

Both satellites are for observing the Earth. Both were built by China for Pakistan.

The leaders in the 2018 launch standings:

19 China
12 SpaceX
7 Russia
5 ULA
4 Japan

In the national standings, China now leads the U.S. 19 to 18. China is also one short of matching its highest ever total of launches for a single year, 20, and it is getting there in just over half a year.

3D image of Ryugu

The lead guitarist of the rock band Queen, Brian May, is also an astronomer, and he has taken Hayabusa-2’s first full close-up image of Ryugu and produced a 3D image of the asteroid.

If you have red/blue 3D glasses you should definitely click on the link and view the image. The asteroid appears much more elongated back to front than it appears in the flat image.

Close look at bright spots in Occator Crater on Ceres

Bright spot in Occator Crater on Ceres

Cool image time! In this week’s release of new images from Dawn, the science released close-ups of one of the bright spots located on the floor of Occator Crater on Ceres. The image on the right, cropped and reduced in resolution to post here, shows one white-topped mesa in that crater.

The geometry of this feature is similar to a mesa or large butte with a flat top. It has been puzzling scientists since its discovery in the early images of the Dawn mission at Ceres. These new images reveal many details. In particular, the relationships between the bright material, mostly composed of sodium carbonate, and the dark background might hold clues about the origin of the facula.

If you click on the image you can see the full image at full resolution.

The sun appears to be coming from the southeast, with the mesa’s cliff’s at the top. Along with some scattered bright spots, the white material appears to have a bright area aligned along the cliff’s rim. The white material also appears to be flowing down one gully in that cliff face.

It is important to remember that these bright spots are generally found in a depression in the crater. scientists now think they are remnants of a volcano-like mound that after erupting slowly slumped back down. Note also that the soft puffiness of the cliff faces probably indicates the lower density of this material due to Ceres’s tiny gravity, about 3% that of Earth’s.

Failed Soviet-era Venus probe to crash to Earth between 2023-2025

A failed Soviet-era probe to Venus that never left Earth orbit is now predicted to crash to Earth sometime between 2023-2025.

The Kosmos 482 interplanetary station, which was unsuccessfully sent towards Venus in 1972 by the USSR, may crash land on Earth between 2023 and 2025, astronomer and cosmonautics historian Pavel Shubin told Sputnik. He couldn’t pinpoint the exact location of the future crash site, but noted that it would be between 52 degrees north and 52 degree south latitude.

The astronomer has studied the data on Kosmos 482 orbit as well as its deterioration and detected that it started to degrade faster due to it getting closer to Earth and experiencing increased gravitational pull.

He also expressed confidence that the station would successfully reach the surface since it was adapted for entering the much harsher atmosphere of Venus so is able to endure stress of 300g and 100 atmospheres. The astronomer is anxious to study the station after it lands in order to analyze how prolonged exposure to open space affected its materials.

It is not likely that this probe will land anywhere where it can be recovered, as most of the Earth is ocean. However, the scientist’s hopes are not unreasonable, as it is always worthwhile for future engineering designs to study how the environment of space effects materials over long periods of time.

China reveals details of its planned heavy-lift and reuseable rockets

The new colonial movement: At a conference in late May a senior designer for China’s space program revealed details of their planned heavy-lift rocket, called the Long March 9 and comparable to SLS, as well as their first reusable rocket, the Long March 8.

The Long March 9 will be a Saturn 5-class super-heavy-lift rocket comparable in capacity to the Space Launch System currently being developed under NASA.

According to Long, the Long March 9 will be capable of lifting 140 metric tons to low Earth orbit, 50 tons to Earth-Moon transfer orbit, and 44 tons to Earth-Mars transfer orbit. The 93-meter-high Long March 9 is expected to have a launch mass of over 4,000 metric tons, producing close to 6,000 tons of thrust.

…Long explained in the lecture that the Long March 8 would be CALT’s first rocket to attempt first stage reusability, which will launch for the first time in 2021.

As previously reported, the Long March 8 is based on the existing Long March rockets, using a core very similar to that of the 3.35-meter-diameter Long March 7, a new-generation medium-lift rocket that had its maiden flight in 2016, with the second stage to be based on the 3-meter-diameter liquid hydrogen-liquid oxygen second stage of the older Long March 3A. The rocket will also use two solid propellant boosters, likely based on the Long March 11.

Long stated that both the first stage and boosters will attempt vertical landing.

At this moment we must take China’s future space plans somewhat seriously. The upper management of their government is packed with former space program managers, all of whom are likely to view space development favorably. They have also done a good job either stealing our ideas and technology and adapting it, or building their own. And they have a somewhat robust economy, much of which has been privatized, that is generating a lot of cash for their government.

We must also remember that though the Chinese are signatories to the Outer Space Treaty, and will not publicly claim any territory they eventually possess on the Moon, Mars, or asteroids, they are likely to privately ignore that treaty and make it very clear to everyone that any territory they possess is theirs, and theirs alone. I also expect them to devise ways to expand that definition of possession to make it as extensive as possible.

The problem we have in competing with them is that our government seems more focused on creating pork instead of affordable and useful rockets. SLS’s design is cumbersome, expensive, and inefficient. It can’t fly often enough to accomplish much. And though private options that are more efficient and practical are now being built, the federal government seems very uninterested in buying them.

Kepler on verge of death

The Kepler space telescope is now almost out of fuel, and scientists have ceased science observations to devote the telescope’s last days downloading its last 51 days of data.

The telescope lasted far longer than planned, and discovered thousands of exoplanets. Its archives will be producing new discoveries for decades. And a new exoplanet space telescope, TESS, is already in orbit to take over.

India tests launch abort system for its own manned capsule

India on July 5 successfully tested its own launch abort system for use on its own manned capsule.

The test was over in 259 seconds, during which the crew escape system along with crew module soared skyward, reached an altitude of nearly 2.7 km, swerved over the Bay of Bengal and floated back to Earth under its parachutes about 2.9 km from Sriharikota.

A video showing excerpts of the test can be viewed here.

India has not yet fully committed to building a manned capsule, but they have been moving forward on testing for several years now, and I expect them to make a commitment within the next year. In fact, I think it likely that India will be the fourth nation, after Russia, the U.S., and China, to launch its own astronauts into space on its own spacecraft.

More launch delays from Russia

Russia has decided to delay one of three commercial Soyuz rocket launches to 2019 due to unspecified “readiness” issues.

The launch of Soyuz-ST launch vehicle with a European satellite was initially scheduled for October 6, a source in the aerospace industry told Interfax. “However, evaluating relevant conditions and the launch vehicle’s readiness, the decision was made to move the launch to November 6,” the source said.

In all, three Russian launch vehicles were expected to take off from the Kourou Space Center by the yearend. Italy’s CSG-1 satellite was scheduled to be launched in November, which was to be followed by the launch of OneWeb’s pilot mini-satellites. Due to the delay of the European weather-forecasting satellite’s launch, the launch of two more rockets from Kourou was endangered. “One of the three launches has to be postponed until next year. This is most likely to be Italy’s CSG-1 satellite. However, a lift-off of satellites under the contract with OneWeb may be adjourned,” he said.

In addition, there was this story (behind a paywall) that noted that the only Proton-M launch in 2018 will also be delayed until 2019.

While such delays in rocket launches are not unusual and are an accepted part of the business, these delays for Russia do not help them. The technical problems in recent years that have caused many launch failures, combined with these delays, will further encourage their international customers to go elsewhere.

Virgin Orbit gets first launch license

Capitalism in space: Virgin Orbit has obtained its first launch license from the FAA.

They hope to fly this first orbital flight before the end of the summer. Previously they have announced launch contracts calling for commercial launches in 2019, which requires these test flights in 2018.

Either way, it appears that, as I predicted in 2016, Virgin Orbit will achieve its first operational flight ahead of Virgin Galactic, even though the latter has been in development more than twice as long.

More close-up images of Ceres

On Monday the Dawn science team released more close-up images of Ceres, taken from Dawn’s final close orbit of the dwarf planet, with the focus of this release Occator Crater and its bright spots.

The current images now show numerous sections of Occator Crater from an altitude of 35 kilometers and with a resolution less than 5 meters per pixel. “The data exceeds all our expectations,” Dr. Andreas Nathues from the MPS, Framing Camera Lead Investigator, says. In the new images, the surface is now ten times better resolved than in the best images from the previous three years.

Impressive avalanches reveal themselves in the new views of the eastern wall of Occator Crater: there are clear signs that material has been recently moving down the slopes; some of it remains stuck halfway. Other images allow a close look at the interplay of bright and dark material in the eastern part of the crater. “We now hope to understand how the bright deposits outside the crater center came about – and what they tell us about Ceres’ interior,” says Nathues. Various analyses of the past years suggest that Ceres has a water-rich crust. Small impacts and landslides regularly expose ice at the surface, which produces a thin exosphere of water vapor.

I have posted some of these images previously, but there are several new ones at the link.

Private Japanese smallsat rocket fails at launch

Capitalism in space: The second test flight of a private Japanese smallsat rocket company, Interstellar Technologies, today failed immediately at launch.

A rocket developed by a Japanese startup company burst into flames seconds after a failed liftoff Saturday in northern Japan.

The MOMO-2 rocket, developed by Interstellar Technologies, was launched in Taiki town on Hokkaido, Japan’s northernmost main island. It was supposed to reach as high as 100 kilometers (62 miles) into space. Television footage showed that the 10-meter (33-foot) pencil rocket lifted only slightly from its launch pad before dropping to the ground, disappearing in a fireball. Footage on NHK public television showed a charred rocket lying on the ground.

The incident caused no injuries.

Rocket science is hard. Competition and freedom carries risks. This company might not be dead, but this failure is definitely a significant setback.

SpaceX successfully launches Dragon to ISS

Capitalism in space: SpaceX early this morning successfully launched Dragon to ISS using its last Block 4 Falcon 9.

Both the first stage and Dragon were used components. As planned, they did not recover the first stage.

The leaders in the 2018 launch standings:

18 China
12 SpaceX
7 Russia
5 ULA
4 Japan

The U.S. and China are once again tied at 18 in the national standings.

At the moment the 2018 worldwide totals for launches is 54, and this is only for the first half of the year. As I predicted in my January review of 2017’s launch totals, we continue to trend to having more than 100 launches in 2018, the first time this has happened since before the fall of the Soviet Union. Then, the numbers were inflated because the Soviets launched a lot of out-of-date spy satellites more out of habit than practicality, which is why, when the Soviet Union fell, the launch totals dropped precipitously. Now, the numbers reflect the real commercial market in space, and suggest real sustained growth, largely fueled by SpaceX’s forcing of lower launch prices.

Complex carbon molecules from within Enceladus

Scientists have determined, using Cassini data, that there are complex carbon molecules spewing from the tiger stripes on Saturn’s moon Enceladus.

Putting it all together, the scientists concluded that the Cassini spacecraft was encountering dust particles rich in carbon in large, complex “macromolecular structures”. The only place this material could have come from was the interior of Enceladus, from which ice, dust and gas is jetting out in geyser-like plumes. These plumes are fed by vapours escaping from a sub-surface ocean.

“So this is a direct sample of the Enceladus ocean,” Khawaja says.

What exactly the newly discovered organic materials are is open for debate, although Khawaja believes they most likely are made of large numbers of ring-like structures cross-linked by hydrocarbon chains. An important hint comes from the fact that the organic-rich grains don’t contain much water, implying that the materials in them don’t easily mix with water. Khawaja hypothesises that they formed deep inside Enceladus, then rose to the top of its underwater ocean, where they formed a thin film akin to an earthly oil slick.

Just to be very clear, they have not discovered life. What they have found however increases the chances that there is life within Enceladus’s underground ocean.

Long March 2C first stage crashes into Chinese town

Footage showing the first stage from yesterday’s Long March 2C launch crashing into a city has now been released.

The Chinese government issues warnings and even evacuates areas calculated to be under risk of impact during these interior launches, but it appears that many locals stick around to film the event. I have embedded below the fold this most recent footage.

The fuel from the first stage of the Long March 2C is very toxic, so China is increasingly facing a bad PR problem they don’t want. They are using their space program, much like the Soviets did, to highlight China’s new first world status. Images of an out-of-control rocket crashing into populated areas does not serve that purpose well. Expect them to accelerate their efforts to either develop reusable first stages, and to abandon this launch site.

Rocket Lab cancels Electron launch for this launch window

In reviewing the motor controller problem that caused a launch scrub earlier this week, Rocket Lab has decided to cancel further launch attempts during the present launch window ending July 6.

In a statement, Rocket Lab said “the motor controller behaviour was similar to that previously identified during wet dress rehearsal operations in April.”

“This issue was analysed and corrective measures [put] in place, however a similar issue presented during yesterday’s pre-launch operational checks. All systems had previously performed nominally during a wet dress rehearsal on 16 June.”

A motor controller is a device that governs commands given to selected hardware and software systems throughout the launch vehicle.

My guess is that they are now worried about a systemic problem with the motor controllers, since the same problem has now occurred on two different units, and it has been an intermittent problem as well.

Trace Gas Orbiter releases new images

Uzboi Vallis entering Holden Crater

Cool image time! Europe’s Trace Gas Orbiter, now in its science orbit around Mars, has released some new pictures (the top five images at the link). The image above shows the very long and meandering canyon Uzboi Vallis as it cuts through the rim of Holden Crater, on the right. If you click on the image you can see a higher resolution version.

With this release the European Space Agency does a very poor job of providing relevant information. It does not provide the latitude/longitude of this image, its scale, or a context image. Thus, I can only guess at its precise location.

Regardless, this area, where Uzboi Vallis enters Holden Crater, is one of the candidate landing sites for the American 2020 Mars rover. Uzboi Vallis is thought to have been formed by flowing water as it cut through a number of craters in the southern high plains.

Fractured surface in Occator Crater on Ceres

fractures in Occator Crater

Cool image time! Dawn, now in its final very close orbit above the surface of Ceres, has released some new images. The image on the right, cropped to post here, was taken from a distance of only 22 miles, and shows a fracture network and some very pronounced cliffs on the wall of Occator Crater. The sunlight is coming from the right. You can also see a bright spot on an east-facing slope with what looks like an apron of lighter avalanche material below it. The flat smooth surface of the floor of this same canyon is likely because it is filled with dust, which has ponded there.

These fractures suggest that the wall of the crater is undergoing a slow motion avalanche, with sections separating off and slowly sagging into the crater below, creating the fractures.

China launches two satellites

China today successfully launched what it called two “technology test satellites,” using its Long March 2C rocket.

No further information about the satellites was released. The Long March 2C is comparable to India’s PSLV rocket, and thus is used for smaller payloads.

The leaders in the 2018 launch standings:

18 China
11 SpaceX
7 Russia
5 ULA
4 Japan

This launch puts China ahead of the U.S. in the national race, 18-17, though SpaceX’s Dragon launch later this week should tie things up again.

Arianespace lowers its launch forecast for 2018

Capitalism in space: Because of a launch miscue in January and a decision by India to delay a satellite launch, Arianespace today admitted that it will not meet its forecast of fourteen launches in 2018.

Arianespace, majority-owned by a joint venture of Airbus and Safran, has so far conducted only three launches, but expects a busier second half, CEO Stephane Israel said. He now expects around 11 satellite launches for the year.

There might be a similar number of launches in 2019, but it is too early to give a definitive forecast, Israel said, adding the company was now focusing on gaining customers for the lower cost Ariane 6 rocket due to debut in 2020.

The article states the launch cost for Ariane 6 will be 40% less than Ariane 5, which cost $100 million per satellite. This brings the per satellite price for Ariane 6 to $60 million, about what SpaceX presently charges. Whether that can compete with the prices that SpaceX and others will be charging in 2020, when Ariane 6 is expected to become operational, remains unknown.

The mysterious chaos terrain of Mars

In one of my weekly posts last month (dated May 14th) delving into the May image release from Mars Reconnaissance Orbiter’s (MRO) high resolution camera, I featured an image of what planetary geologists have labeled chaos terrain, a hummocky chaotic terrain that has no real parallel on Earth but is found in many places on Mars.

This month’s image MRO release included two more fascinating images of this type of terrain. In addition, the Mars Odyssey team today also released its own image of chaos terrain, showing a small part of a region dubbed Margaritifer Chaos. Below, the Mars Odyssey image is on the right, with one of the MRO images to the left. Both have been cropped, with the MRO image also reduced in resolution. The full MRO image shows what the MRO science team labels “possibly early stage chaos” on the rim of a canyon dubbed Shalbatana Vallis.

The dying Russian space program

Three articles today illustrate starkly the sad state of the Russian space program.

The first story describes the serious problems for Russia’s first lunar probe in decades.

Its launch was originally scheduled for 2016 but was postponed to 2019 mainly because of lack of funding. Roscosmos allocated a budget of 4.5 billion rubles to NPO Lavochkin, Luna-Glob’s builder, as recently as October 2016.

Since then, almost everything has gone according to the plan, except with a crucial instrument called BIB, the probe’s inertial measurement unit. Provided by the Russian company NPO IT – located in the city of Korolyov, not far from ISS Mission Control – the BIB should provide the onboard computer with the necessary information to ensure guidance on the path from the Earth to the Moon.

However, BIB testing at NPO IT showed unexpected results, clearly indicating it was not working properly. The designers of this system noted it won’t be ready for the 2019 launch window, which resulted in NPO Lavochkin trying to replace it with a European equivalent called ASTRIX, designed by Airbus Defence & Space.

However, sanctions against Russia – from the European Commission in the fallout of the Ukrainian crisis – strictly forbid such a deal.

A different Russian instrument could replace BIB, but it won’t be ready in time, further delaying the mission to 2021 when many of its other instruments will be past their own due dates.

The second story describes the end of Russia’s Proton rocket, first built in the mid-1960s and since the 1990s has been its commercial workhorse. Faced with numerous failures and an inability to compete with SpaceX, it has lost its market share, and will now be replaced by Russia’s new Angara rocket. The problem is that Angara itself is not ready, and will likely not be operational until 2021, at the earliest.

The third article describes some of the reasons why Angara will take so long to be operational. Vostochny, Russia’s new spaceport, doesn’t have the necessary facilities, and it appears there is a disagreement within the Russian aerospace community about how fast those facilities can be built, or even if all are needed immediately. The top management in Roscosmos seems reluctant to switch all operations from Baikonur, probably for political reasons, while the expert quoted by the article says they should do it fast.

Either way, the entire Russian space program seems mired in bad technology, overpriced products, and poor and confused management. They have lost most of their commercial international customers, are about to lose NASA as well when Dragon and Starliner begin flying American astronauts, and do not have the resources to replace this lost income. Further, the top-down centralized management by the government of the entire aerospace industry has worsened these problems by stifling competition and innovation.

Russia might recover eventually, but for the next decade expect them to play a very minor role in space.

The slow death of Planetary Resources

Link here. The article tries to put a positive spin on the company’s decline, but the facts described tell a different story, with its failure to raise investment capital essentially forcing it to shut down, with its best people leaving for greener pastures.

[The fund-raising failure] forced a sharp reduction in Planetary Resources’ workforce. How sharp? Lewicki declined to say, but LinkedIn’s listings show that a number of employees have moved on to Blue Origin, Amazon and other companies.

Several former members of the team have started up a new engineering services company called Synchronous. Maggie Scholtz, a Planetary Resources veteran who is now Synchronous’ president of aerospace and space, will be one of the speakers at the NewSpace conference. The event gets under way on Tuesday at the Hyatt Regency Lake Washington in Renton, Wash. Other Synchronous partners include Chris Voorhees, who was Planetary Resources’ chief engineer until February; Peter Illsley, Planetary Resources’ former director of mechanical and thermal engineering; Brian Geddes, former director of software; and Rhae Adams, former director of mining and energy.

Planetary Resources had to let a robotic worker go as well. Arkyd-6A, the experimental Earth-observing satellite that was launched for the company in January, is now idle in low Earth orbit.

When this company made its splashy appearance in 2012, claiming it planned to do asteroid mining, I said hogwash. They weren’t an asteroid mining company, at best they were a cubesat-sized orbiting telescope company, testing technologies for looking at asteroids.

In the end, they weren’t even that. Arkyd-6A has taken one picture of the Earth, and is not competitive with numerous other Earth-observation companies that have already launched many superior and commercially profitable satellites.

I am not optimistic for the future of this company. The lesson it provides however is important. Companies that oversell themselves should be viewed with great skepticism.

Falcon 9 Dragon launch to set used booster turnaround record

Capitalism in space: The planned launch on June 29th of Dragon to ISS will set a new turnaround record for a used first stage, just over two months.

This first stage is not a Block 5 first stage, it is the last older Block 4. What this quick turnaround means for the upcoming Block 5 launches however is important.

Although CRS-15 will likely see its venerable Block 4 Falcon 9 booster expended in the ocean without a recovery attempt, the speed of Falcon 9 B1045’s refurbishment is thrilling for another, more abstract reason: if the design functions largely as intended, a Falcon 9 Block 5 booster should be able to handily crush that already impressive record with ease, and one will perhaps do just that within a handful of months of this launch.

Currently scheduled for no earlier than (NET) July 19 and late July to early August, the Telstar 19V and 18V communications satellites will require their own Block 5 launches roughly a month from today, and July 20’s Iridium NEXT-7 mission will further require its own Falcon 9 Block 5 booster for a mission from California. It remains to be seen what boosters will launch those three missions, as well as an additional two SpaceX missions tentatively scheduled for August and September.

In other words, there is a very strong likelihood that SpaceX will be reusing its Block 5 boosters almost immediately this summer.

Ryugu from 25 miles

Ryugu from 25 miles

The Hayabusa-2 science team has released its first image of Ryugu, posted to the right, from a distance of only 25 miles. From the project manager:

The shape of Ryugu is now revealed. From a distance, Ryugu initially appeared round, then gradually turned into a square before becoming a beautiful shape similar to fluorite [known as the ‘firefly stone’ in Japanese]. Now, craters are visible, rocks are visible and the geographical features are seen to vary from place to place. This form of Ryugu is scientifically surprising and also poses a few engineering challenges.

First of all, the rotation axis of the asteroid is perpendicular to the orbit. This fact increases the degrees of freedom for landing and the rover decent operations. On the other hand, there is a peak in the vicinity of the equator and a number of large craters, which makes the selection of the landing points both interesting and difficult. Globally, the asteroid also has a shape like fluorite (or maybe an abacus bead?). This means we expect the direction of the gravitational force on the wide areas of the asteroid surface to not point directly down. We therefore need a detailed investigation of these properties to formulate our future operation plans.

They are going to have to spend some time in orbit to figure out not only where to land, but how to do it. More information on the mission can be found here.
