Iridium launches might use reused Falcon 9 first stages
Capitalism in space: Iridium is considering using Falcon 9 previously flown first stages for its later already contracted launches with SpaceX.
Iridium is launching 75 of its 81 second-generation Iridium Next satellites using eight Falcon 9 launches, the first of which took place Jan. 14. In a conference call with reporters June 19, Desch said Iridium’s original contract with SpaceX calls for new Falcon 9s for each mission, but if SpaceX can improve its launch schedule with pre-flown stages, Iridium would consider them for missions in 2018. “While we are currently flying first flown launches, I’m open to previously flown launches, particularly for the second half of our launch schedule,” said Desch.
Desch said there are three criterion by which Iridium would decide whether to use a pre-flown rocket: schedule, cost and reliability — of which schedule is the most important. “Would [pre-flown rockets] improve the current launch plan that I have with brand-new rockets that I’ve basically contracted for a number of years ago and have budgeted for and have paid for?” Desch asked. “That’s the first thing: will they improve my schedule, because schedule to me is very very important.”
I think this tells us that Iridium is waiting to see if this week’s launch of a Bulgarian satellite on a reused first stage is successful. The article also also notes that they are still negotiating over price for using “flight proven” first stages.

Russia offers Soyuz capsule for tourist flights, even after it is replaced
Capitalism in space: The Russian company that makes the Soyuz capsule has announced that it intends to continue flying the capsule, even after the new Federation replacement capsule is operational.
“I think that the Soyuz has the right to continue its life. As long as there exists a space tourism market and this spacecraft enjoys confidence, this all should be used as essential components,” the CEO said. Energiya is also considering the possibility to upgrade the Soyuz for circumlunar missions. “If we manage to do it faster, we will have a chance to perfect important systems on it, that will be further used on the Federation,” Solntsev noted.
Energiya is now part of the Russian space agency Roscosmos and is controlled by the government. Thus, for it to do this will still require government approval. Will the Russian government allow the old capsule to exist when the new one begins flying? That would be a form of competition, something Russia hasn’t really encouraged since the fall of the Soviet Union. We shall see.

Russia moves to capture the smallsat launch market
Glavkosmos, a division in Roscosmos, Russia’s nationalized aerospace industry, is working to capture a large part of the new smallsat launch industry.
Glavkosmos, a subsidiary of Russian state space corporation Roscosmos, said June 14 that it will launch 72 small satellites as secondary payloads on the Soyuz-2.1a launch of the Kanopus-V-IK remote sensing satellite, scheduled for July 14 from the Baikonur Cosmodrome in Kazakhstan.
Vsevolod Kryukovskiy, launch program director at Glavkosmos, said in a June 19 interview that the smallsat customers for that launch come from the United States, Germany, Japan, Canada, Norway and Russia. He declined to identify specific customers, although he said they include both companies and universities. The spacecraft range in size from single-unit cubesats up to a 120-kilogram microsatellite. “We’ll do the most technically challenging cluster mission ever,” he said. The satellites will be deployed into three separate orbits, after which the rocket’s upper stage will perform a deorbit maneuver.
Kryukovskiy said Glavkosmos is also arranging the launch of secondary payloads on two Soyuz launches planned for December from the new Vostochny Cosmodrome in Russia’s Far East region. “We’ll have about 40 microsats that we’ll launch from Vostochny, and that will be the first international launch from this new Russian cosmodrome,” he said.
These numbers are in the same range as when India launched 103 smallsats on a single rocket, and suggest that Russia is trying to grab the market share that the new small rocket companies are aiming at.

Arianespace gets another launch contract
Capitalism in space: Arianespace has won new contracts for two launches of its Vega rocket.
More important however was this tidbit:
And, with another two flights to geostationary orbit booked for its Ariane 5 heavy lifter, the Arianespace orderbook now stands at €4.8 billion ($5.3 billion), with 53 launches for 28 customers: 18 using Ariane 5, 25 for the mid-weight Soyuz and 10 for Vega/Vega C.
Compare that manifest with Russia’s, which now only has 15 commercial launch contracts through 2023. Compare it also to SpaceX’s which lists about 30 commercial launches, excluding its NASA cargo and crew missions to ISS.
It would appear that Russia has so far been the big loser in the new competitive launch industry. This can of course change, especially if Russia fixes its production problems, becomes a reliable launch company, and offers competitive prices.

China’s Tianzhou-1 completes second docking test
Tianzhou-1, China’s first unmanned cargo freighter, has successfully completed its second docking with the test space station module Tiangong-2.
The two spacecraft will next separate, fly independent of each other for three months, when Tianzhou-1 will attempt a third more difficult docking attempt.

Update of Kepler exoplanet catalog
Worlds without end: The Kepler science team has released an update of the space telescope’s exoplanet candidate list, adding 219 new exoplanet candidates.
NASA’s Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new planet candidates, 10 of which are near-Earth size and orbiting in their star’s habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet. This is the most comprehensive and detailed catalog release of candidate exoplanets, which are planets outside our solar system, from Kepler’s first four years of data. It’s also the final catalog from the spacecraft’s view of the patch of sky in the Cygnus constellation.
With the release of this catalog, derived from data publicly available on the NASA Exoplanet Archive, there are now 4,034 planet candidates identified by Kepler. Of which, 2,335 have been verified as exoplanets. Of roughly 50 near-Earth size habitable zone candidates detected by Kepler, more than 30 have been verified.
Additionally, results using Kepler data suggest two distinct size groupings of small planets. Both results have significant implications for the search for life. The final Kepler catalog will serve as the foundation for more study to determine the prevalence and demographics of planets in the galaxy, while the discovery of the two distinct planetary populations shows that about half the planets we know of in the galaxy either have no surface, or lie beneath a deep, crushing atmosphere – an environment unlikely to host life.

Did China experience a launch failure today?
The status of a Chinese launch attempt of a communications satellite today remains unknown, hours after launch.
China launched its seventh mission of 2017 on Sunday, lofting the Zhongxing-9A (ChinaSat-9A) communications satellite, but -unusually – there has been no official status update in over three hours since liftoff. The Long March 3B/G2 lifted off from the Xichang Satellite Launch Centre in the hills of Sichuan Province at 00:12 local time on monday (16:12 UTC, 12:12 EDT on Sunday), following on from Thursday’s launch of the country’s first space observatory.
Apparent video footage and locals on social media surprised by the rumbling of the launch vehicle confirmed liftoff. However, official confirmation of launch success, often within an hour, has not followed, bringing speculation of some degree of failure.
Nothing has as yet been confirmed, so this launch might not be a failure.
Update: A problem with the third stage placed the satellite in the wrong orbit.

SpaceX delays Bulgarian satellite launch to replace valve
Capitalism in space: In order to replace a valve in the payload fairing of its Falcon 9 rocket, SpaceX has decided to delay its Florida launch of a Bulgarian television satellite until Friday.
Meanwhile, they have another launch scheduled for Sunday out of Vandenberg. If both fly successfully this will make the weekend very busy for SpaceX.

New smallsat rocket company plans first flight of aerospike engine
ARCA Aerospace has announced that it will perform the first test flight reaching space of an aerospike rocket engine this coming August.
ARCA Space Corporation has announced the first test-launch of its Demonstrator 3 space vehicle at Spaceport America in August. This will mark the first space flight of an aerospike rocket engine. Aerospike rocket engines are described as significantly more fuel efficient than the current engines and could make launches attempting to bring satellite payloads to space more affordable. Demonstrator 3 will perform a suborbital space flight up to an altitude of 100 kilometers above the New Mexico desert.
Their goal is to build a rocket they have dubbed Haas 2CA for the smallsat industry.
There is an interesting video at the link from the company showing their engineers hand-building this first suborbital test rocket, which the company also says is the first of a weekly series leading up to the test launch. More information about the company can be found at their website. According to their schedule, they hope to make the first orbital flight in 2018, and begin commercial operations by the end of that year.

The state of the global aerospace industry
A new European analysis of the global aerospace industry suggests it is both growing and changing significantly.
Several takeaways that indicate future trends.
- The government space spending has been stable the past 5 years, there was a 2% drop in 2016
- The number of nations spending money on space has grown significantly in the past decade, from 47 to 70
- Spending is shifting from military to civilian efforts
- Russia experienced a 25% cut in aerospace spending in 2016
- China passed Russia in spending in 2016
- U.S. government spending stabilized in 2016 after a 25% decline since 2010
A drop in government spending in space is not proof that the industry is shrinking. In fact, it might be a sign of robust growth, in that it is no longer necessary to depend on coerced tax dollars to finance space projects. Instead, it suggests that because there are increasing profits to be made in space, the government is being replaced by a vibrant private sector. It also suggests that the private sector is finding ways to do things cheaper, which is saving the government money and allowing it to lower its budgets.
The second bullet point above reinforces these conclusions. Even though overall government spending has been stable, more countries have entered the market. More is being done with the same amount of money, and these lower costs are allowing new players to participate. The last bullet point also supports these conclusions. Even though the report notes a significant drop in U.S. government spending on space since 2010, it is very clear to me that the industry has actually prospered in these same years, fueled by a growing private sector.

Air Force budget reveals cost differences between ULA and SpaceX
Eric Berger at Ars Technica has found that the most recent Air Force budget provides a good estimate of the price ULA charges the military for its launches.
According to the Air Force estimate, the “unit cost” of a single rocket launch in fiscal year 2020 is $422 million, and $424 million for a year later.
This is a complex number to unpack. But based upon discussions with various space policy experts, this is the maximum amount the Air Force believes it will need to pay, per launch, if United Launch Alliance is selected for all of its launch needs in 2020. ULA launches about a half-dozen payloads for the Air Force in a given year, on variants of its rockets. Therefore, the 2020 unit cost likely includes a mix of mostly Atlas V rockets (sold on the commercial market for about $100 million) and perhaps one Delta rocket launch (up to $350 million on the commercial market for a Heavy variant).
In other words, the $422 million estimate per launch is the most they will pay. Atlas 5 launches will certainly be less, about $100 to $150 million, while the Falcon 9 will likely be under $100 million. What they are doing is budgeting high so they guarantee they have the money they need to pay for the most expensive launches, usually on the Delta Heavy.
From my perspective, they are budgeting far too high, and if I was in Congress I would insist that this number be reduced significantly, especially considering this Air Force statement on page 109 of the budget document [pdf]:
The Air Force, National Reconnaissance Office (NRO), and the National Aeronautics and Space Administration (NASA) agreed to a coordinated strategy for certification of New Entrants to launch payloads in support of NSS and other USG requirements which has so far resulted in the certification of one New Entrant. The Air Force continues to actively work with potential New Entrants to reliably launch NSS requirements. The Government may award early integration contracts to ensure each potential offeror’s launch system is compatible with the intended payload. Beginning in Fiscal Year 2018, the Air Force will compete all launch service procurements for each mission where more than one certified provider can service the required reference orbit. [emphasis mine]
The “New Entrant” is of course SpaceX. They are also saying that they are going to encourage competitive bidding now on all future launch contracts.

China’s Tianzhou-1 freighter completes second refueling test
Tianzhou-1, China’s first unmanned freighter, has successfully completed its second refueling test while docked with that country’s Tiangong-2 space module.
The test was successfully completed at 18:28 Beijing time on June 15th (10:28 UTC), according to an announcement (Chinese) from the China Manned Space Agency (CMSA).
Tianzhou-1 and the Tiangong-2 space station test bed module have been coupled for 54 days in orbit at around 390 kilometres above the Earth since April 22, following launch of Tianzhou-1 on April 20.
A first 29-step, five-day refuelling process was successfully concluded on April 27, marking a major step in China’s space station plans. The second test is understood to have taken two days.
The freighter will next undock, fly free for several months, and then attempt a third docking, this time doing so in only six hours versus the two day maneuvers it has so far completed.

Titan’s clearing northern skies
The image of Titan on the right, reduced in resolution to show here, was taken by Cassini less than a week ago, on June 9, as it continues its last orbits of Saturn prior to crashing into the gas giant’s atmosphere in September.
NASA’s Cassini spacecraft sees bright methane clouds drifting in the summer skies of Saturn’s moon Titan, along with dark hydrocarbon lakes and seas clustered around the north pole. Compared to earlier in Cassini’s mission, most of the surface in the moon’s northern high latitudes is now illuminated by the sun. …Summer solstice in the Saturn system occurred on May 24, 2017.
When Cassini arrived more than a decade ago, it was winter on Titan’s northern hemisphere, and the atmosphere was thick with haze. Now the sky is clearing as the stormy weather shifts to the winter in the southern hemisphere.
As with yesterday’s global map of Mimas, this image is in many ways a farewell look at Titan. While Cassini will likely get a few more global images of the Saturn moon before the mission ends in September, this image essentially marks the end of our ability to observe this strange planet closely, for decades to come. When Cassini crashes into Saturn, our vision at Saturn will go blind. And no one knows when our sight there will return, as no mission is presently in the works, or is even being considered, to return to Saturn.

Digitizing Venice’s 1,000-year-old archives
Link here. The article describes an ambitious effort to make this archive, much of which has never been read, easily accessible and searchable using modern digital technology.
As Venice’s empire grew, it developed administrative systems that recorded vast amounts of information: who lived where, the details of every boat that entered or left the harbour, every alteration made to buildings or canals. Modern banking was invented in the Rialto, one of Venice’s oldest quarters, and notaries there recorded all trading exchanges and financial transactions.
Crucially, those records survived through turbulent centuries. While the rest of Europe was roiled by its perpetually warring monarchs, from the eighth century onwards Venice began to develop into a stable republic that provided the peace and order required for trade to flourish. In many ways it was a model democracy. The people elected a leader — the doge — supported by various councils, whose members were also usually elected. Governance was secular, but for the most part co-existed tolerantly with religion.
French emperor Napoleon Bonaparte put an end to the Serene Republic in 1797. En route to Vienna during his attempt to conquer the Austro-Hungarian Empire, he declared Venice’s secular and democratic governance to be a form of autocracy, and the city to be an enemy of the revolution. He forced the republic to dissolve itself. In 1815, the old Frari was turned into the State Archives of Venice. Over the next decades, all state administrative documents, including death registers, were transferred there, along with medical records, notary records, maps and architectural plans, patent registers and a miscellany of other documentation, some from elsewhere in Italy. Particularly significant are ambassadors’ reports from wider Europe and the Ottoman Empire, providing a unique source of detailed information about daily life. “Venetian ambassadors were the most observant travellers, trained to find out things like what was being unloaded at the docks, or what a prince or other high-up was like as a person,” says Daston. “Their reports were full of gossip and intrigue.”
Most of the archive, predominantly written in Latin or the Venetian dialect, has never been read by modern historians. Now it will all be systematically fed into the Venice Time Machine, along with more unconventional sources of data, such as paintings and travellers’ logs.
Venice is a particularly important component of European history, as in many ways it was the last remnant of the Roman Empire, founded by Romans even as their empire was collapsing around them. It then lasted almost a thousand years, and became throughout the Middle Ages a powerful and important center of European trade. Moreover, the growth of this strange city in a bog is in many ways a mystery. This archive will actually allow researchers and historians to finally begin to understand how these events unfolded.

Over the next decades, all state administrative documents, including death registers, were transferred there, along with medical records, notary records, maps and architectural plans, patent registers and a miscellany of other documentation, some from elsewhere in Italy. Particularly significant are ambassadors’ reports from wider Europe and the Ottoman Empire, providing a unique source of detailed information about daily life. “Venetian ambassadors were the most observant travellers, trained to find out things like what was being unloaded at the docks, or what a prince or other high-up was like as a person,” says Daston. “Their reports were full of gossip and intrigue.”
Most of the archive, predominantly written in Latin or the Venetian dialect, has never been read by modern historians. Now it will all be systematically fed into the Venice Time Machine, along with more unconventional sources of data, such as paintings and travellers’ logs.
Venice is a particularly important component of European history, as in many ways it was the last remnant of the Roman Empire, founded by Romans even as their empire was collapsing around them. It then lasted almost a thousand years, and became throughout the Middle Ages a powerful and important center of European trade. Moreover, the growth of this strange city in a bog is in many ways a mystery. This archive will actually allow researchers and historians to finally begin to understand how these events unfolded.
Truck driver killed in fire related to crash of Soyuz stage in Kazakhstan
A truck driver has died in an effort to extinguish a fire related to the crash in Kazakhstan of the stages from the Soyuz rocket that earlier this week launched a Progress freighter to ISS.
This story does not indicate any failure on Russia’s part during the launch. What it does highlight is the problematic location of their Baikonur spaceport, which requires expendable first stages to crash on land. In fact, this incident also suggests it wise for the Russians, and the Kazakhstans, to consider developing recoverable first stages that can land in a controlled manner, as SpaceX has, in order to make this spaceport more useful and safer.

China launches X-ray space telescope
China today launched the Hard X-ray Modulation Telescope (HXMT), also dubbed Insight by Chinese news sources.
The HXMT carries three x-ray telescopes observing at energies ranging from 20 to 200 kilo-electron volts as well as an instrument to monitor the space environment, according to its designers. While orbiting 550 kilometers above the planet, the HXMT will perform an all-sky survey that is expected to discover a thousand new x-ray sources. Over an expected operating lifetime of 4 years, it will also conduct focused observations of black holes, neutron stars, and gamma ray bursts.
More here. This is China’s first home-grown X-ray space telescope, and its launch once again illustrates that, for at least the next few decades, China intends to be a major player in the exploration of the solar system.

A new map of Mimas
The Cassini science team has released what will be the best map of Saturn’s moon Mimas for many decades to come. A reduced resolution version is above, and was updated after the most recent fly-bys in November 2016 and February 2017.
The moon’s large, distinguishing crater, Herschel, is seen on the map at left. The map is an equidistant (simple cylindrical) projection and has a scale of 710 feet (216 meters) per pixel at the equator. The mean radius of Mimas used for projection of this map is 123.2 miles (198.2 kilometers). The resolution of the map is 16 pixels per degree.
Since Cassini is in its final orbits and will crash into Saturn in September, and no other Saturn mission is even being planned, do not expect a better map for a very long time.

China to attempt to grow potatoes on Moon
China’s Chang’e-4 lunar rover/lander, set to launch in 2018, will include a small experiment that will attempt to grow potatoes from seeds.
Note that I have just realized that I have been confusing Chang’e-5 with Chang’e-4. Chang’e-5 is a sample return mission that they hope to launch this year. It does not include a rover. Chang’e-4 is a lander/rover mission that is planned for 2018.

Boeing cuts management, streamlines its operations
Capitalism in space: In an effort to better compete, Boeing is eliminating a layer of management and cutting 50 jobs in its defense and aerospace division.
The changes split management into smaller units so they can make faster decisions in their specific fields. This includes separating their space and missile division from other activities. This quote however says it all about the accelerating competition in the space business.
The changes are designed to speed decision-making, [defense division head Leanne Caret] said in an interview. “Everything is moving faster,” she said of the competitive environment for defense contractors.

Design questions might delay construction of China’s first big optical telescope
A disagreement over the design of what China hopes would be, for a short while, the world’s largest optical telescope might delay that telescope’s construction.
On one side is an established engineering team, led by a veteran optics expert responsible for the nation’s largest existing telescope, that is eager to push ahead with an ambitious design. On the other are astronomers reveling in a grassroots priority-setting exercise—unprecedented for China—who have doubts about the ambitious design and favor something simpler.
Now, a panel of international experts has reviewed the designs and come out squarely in favor of the simpler proposal, according to a copy of the review obtained by Science. But the conclusion has not ended what one Chinese astronomer calls “an epic battle” between the high-ranking engineers accustomed to top-down control over projects and the nascent grassroots movement.
The telescope would have a mirror diameter of 12-meters, topping the 10.4 meter Gran Telescopio Canarias in the Canary Islands. To get it built in time to be the largest, they need to approve the construction plan by 2018.
The story is interesting in that is highlights the technical problems that exist for these large telescopes, most of which have had serious engineering issues that have limited their scientific output. The disagreement here is caused by an effort by some Chinese scientists to avoid these problems by using a simpler design.

Russians successfully launch Progress to ISS
A Russian Soyuz rocket successfully launched a Progress freighter to ISS early today.
That’s the second Russian launch in less than a week, after a very long pause caused by the discovery of corruption in one of their major engine factories. Though the Russians presently only have two launches scheduled for July, and none scheduled for August, I suspect that this will change in their effort to clear their launch backlog.

KFC pays to put chicken sandwich on four day World View shakedown flight
Capitalism in space: A publicity stunt by Kentucky Fried Chicken to sell a new chicken sandwich will help pay for the the first long shakedown of World View’s Stratollite balloon.
For World View Enterprises, the flight is expected to serve as a four-day shakedown cruise for its “Stratollite” system, which could eventually send military and commercial imaging payloads to the edge of the atmosphere for months at a time. “When KFC first brought this to us, we had a good chuckle,” World View CEO Jane Poynter told reporters during a teleconference today. But then the Arizona-based company realized there could be a serious point behind the project. “If you can fly a chicken sandwich to the edge of space … you can fly really just about anything,” Poynter said.
Besides, the payment that KFC is providing for the publicity will cover the cost of the test flight, including the expense of beaming down live HD video from a height of 60,000 to 75,000 feet, Poynter said.
Neither she nor KFC brand communications director George Felix would say precisely how much the fast-food chain is paying, but Felix said “we’re fully confident that this is going to be worth every penny.” For reference, NASA has paid World View as much as $440,000 for balloon test flights.
What is interesting to me is how World View appears to have significantly backed off its effort to sell and fly tourists on a balloon.
When World View was founded in 2013, the company’s main objective was to provide hours-long tours to the stratosphere in a pressurized Voyager capsule for $75,000 a ticket. Since then, World View has pivoted to the Stratollite concept, but it still intends to fly people someday. “We’re actually making huge progress,” Poynter said.
Poynter is no longer giving out a timetable for the start of Voyager tours, but she said two more Stratollite missions are scheduled for this summer. MacCallum, who is Poynter’s husband, said a full-scale mass simulator for the Voyager capsule is due to be flown by the end of the year.
All in all, the suborbital space tourism business appears, at least for now, to be fading, overwhelmed by the new and growing orbital launch industry.

Worm grows 2 heads on ISS
The uncertainty of science: For reasons that are not yet understood, a flatworm fragment flown to ISS in a microgravity experiment regenerated with two heads.
But the most dramatic difference was a type of regeneration observed in one of the 15 worm fragments sent to the ISS. That worm returned to the scientists with two heads (one on each end of its body), a type of regeneration so rare as to be practically unheard of — “normal flatworms in water never do this,” Levin told Live Science. When the researchers snipped both heads off back on Earth, the middle portion regenerated into a two-headed worm again.
“And these differences persist well over a year after return to Earth!” Levin said. “Those could have been caused by loss of the geomagnetic field, loss of gravity, and the stress of takeoff and landing — all components of any space-travel experience for living systems going to space in the future,” he said.
The flatworms that flew in space showed other significant differences from the control group that stayed on Earth, further suggesting that for flatworms at least the environment of weightlessness causes more problems that were expected.

A dust-off broom for Mars
Romanian engineers have developed a small plasma jet capable of blowing Martian dust from solar panels and other equipment that can be used by future missions.
The “plasma broom” solution developed by Ticoş and colleagues uses bursts of plasma jet produced by a simple plasma accelerator. When a large current is passed through two electrode plates separated by a field of rarefied gas, the voltage difference between the two electrodes ionizes the gas, creating the plasma. In the broom, this is done with a coaxial gun – the two metal electrodes are arranged as an inner rod within a hollow cylindrical shell. The discharge current flowing through the central rod electrode produces a magnetic field, which, together with the electric field, exerts a Lorentz force on the ionized gas that expels it. “The trick is that you need a quite high current in order to produce a reasonable magnetic field and this can be achieved more conveniently in a pulsed operation,” Ticoş explains. “For a fraction of a second (100 µs) the current is very high (several kiloamps) and the force pushing the plasma is quite strong.” During a pulse, the plasma is expelled at a very high speed – several kilometres per second – and so can simply blow dust away from an area two to four times bigger than the diameter of the jet.
An advantage of the plasma broom is that it uses low-pressure CO2 as the gas between the electrodes. This is particularly ideal for operation on Mars as the atmospheric pressure there is 150 times lower than on Earth and the atmosphere is 96% CO2. This means the gun will be able to function in “open” Martian atmosphere without the need for a pump or gas bottle. Ticoş and colleagues have also considered the energy required for the cleaner to function on Mars. This depends on the voltage the gun operates at and can vary between a few hundred to a few thousand Joules per pulse. “We did an energy budget estimate taking into account the solar irradiance on Mars,” says Ticoş, “and it appears perfectly feasible to fire a few shots even on a daily basis for cleaning the solar panels, which will boost considerably the energy production rate.”
Essentially, they are using ion engine concepts to create a can of dust-off, using the Martian atmosphere itself as the can.

What ISRO charges for a launch
Capitalism in space: This article, outlining the overall expenditures and earnings of India’s space agency, ISRO included this tidbit about the price it charges for launches:
Several companies like SpaceX’s Falcon 9, Russia’s Proton ULA, and Arianespace are big names in the space but ISRO’s Antrix provides competitive rates for commercial launches. ISRO, that has now become a specialist in launching satellites, cost a third of SpaceX launches. The low rates are probably because of ISRO’s location while its Indian engineers earn a fraction of the salaries that engineers would command in foreign countries. [emphasis mine]
If India does charge in the range of $20 to $30 million per launch they are in a strong position to compete with SpaceX, even after it reduces its prices because of the use of used first stages.

Russia lowers its Proton launch plans for 2017
Though they are about to resume Proton launches, Russia today revealed that they only intend to launch the rocket five times in 2017, not seven as announced earlier.
Russia plans five Proton-M carrier rocket launches this year, including three commercial launches, Khrunichev Space Center CEO Andrei Kalinovsky told TASS on Wednesday. “Our plans for this year also additionally include four Proton-M carrier rocket launches. These are two commercial launches with Amazonas 5 and AsiaSat 9 satellites, and also two federal launches,” the chief executive said.
Even more interesting, the article notes that Russia only has contracts to launch 15 commercial satellites through 2023. That’s a launch rate of only about 2.5 to 3 commercial Proton launches per year, a rate that seems much less than in the past. Moreover, while they say they haven’t lost any customers in the past year, it also appears they haven’t gotten any either.

China to ramp up manned missions to build space station
In order to build its space station, beginning in 2019, China will increase its manned mission rate, completing four missions in five years.
This is still a somewhat glacial pace, compared to other nations. It will seem even slower based on what I expect will start happening once a number of competitive private American rockets begin hauling tourists into space.
The article notes one additional tidbit about China’s station. They plan to run 3 to 6 month long missions there.

Air Force awards SpaceX contract to launch next X-37B mission
Capitalism in space: The Air Force has awarded SpaceX the contract to launch the next X-37B mission, presently scheduled to launch in August.
The contract amount was not announced, but it certainly is going to be less than ULA charged for its own launches of the X-37B. Also, this launch is scheduled only two months hence, which means SpaceX has to somehow wedge it into its already crowded schedule.
