What ISRO charges for a launch

12:40 am

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

8:52 am

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

5:10 pm

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

4:47 pm

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.

The atomic rocket that never was

11:19 am

Link here. The article is filled with overstatements and even a few outright errors, such as in the second paragraph when it makes the false assertion that SLS will be “the largest booster ever built.” (The Saturn 5 was more powerful. So was the Soviet Union’s Energia.)

Furthermore, the key to understanding how minor and inconsequencial Project Orion was is to note the total amount of money spent: only $10.5 million. This was merely a design study, something that NASA did (and still does) routinely, most of which never get beyond power-point presentations. Project Orion was similar, never reaching project stage. If it had been done today it would have also been nothing more than a power point presentation.

I also remember when this whole concept got cancelled and was revealed. No one took it seriously, since everyone understood that the technology available in the 1960s was simply not ready for such a project.

Nonetheless, it is interesting reading, especially since the technology today is significantly advanced. We might actually be approaching a time where this concept can finally move to design and construction.

Jupiter’s cloud-tops, up close

4:16 pm

Jupiter's cloud tops

Cool image time! On the right is a cropped and reduced resolution section from this image from Juno. It shows the top of some of Jupiter’s clouds, swirling about chaotically.

What I find most fascinating is how this image reveals the different elevations of some of these cloud belts. The swirling clouds on the left and bottom of the image are clearly higher than the dark areas to the top and right. They are in fact casting their shadows on those lower cloud-tops.

To really understand the interactions taking place here, however, will require satellites capable of continually tracking these clouds over time. Unfortunately, Juno cannot do this. Though it will provide us periodic snapshots of specific areas, its long 53-day orbit means that it will not return to view the same areas very frequently. Making movies of the evolution of these clouds will be difficult, if not impossible.

NASA considering using used first stages for Dragon cargo launches

11:15 am

Capitalism in space: With SpaceX’s successful launch on June 3 of a used Dragon cargo capsule to ISS, NASA is now considering using used Falcon 9 first stages for later cargo missions.

“That question has been posed,” Ven Feng, manager of the ISS Transportation Integration Office at NASA’s Johnson Space Center in Houston, said during a post-launch press conference Saturday. “We are looking at it,” he added. “We’re evaluating every aspect of it very carefully, and there is no schedule yet when we might go down that path.”

NASA officials made the same kind of cautious statements several years ago when SpaceX proposed flying a used Dragon capsule. In other words, they are going to do it, it just takes the bureaucracy time to mull the idea over and finally accept it.

Turkish company announces plans to build commercial rocket

11:09 am

Capitalism in space: A Turkish company, Roketsan, has announced its plans to build a rocket capable of launching both commercial and Turkish government satellites.

A Rocketsan press release that came out right before the Turkish International Defence Industry Fair held May 9-12, 2017, revealed the company’s plan to develop an independently funded satellite launch vehicle (SLV). The SLV will be Turkey’s first domestically produced rocket and it will be capable of launching low-Earth-orbiting satellites to an altitude of 500–700 km.

The SLV development is still in the conceptual design phase, but is planned to have a liquid propulsion system and falls in line with the SLS project. The SLS project involves a three-fold plan, the first step of which is to develop an SLV for the Turkish government.

Even though the SLV development is a fully private venture by Rocketsan, it will be Turkey’s own vehicle to use for government missions. That being said, the SLS project has much bigger and ambitious goals that require two additional phases. The next steps of the project will be the establishment of both a Satellite Launch Centre and Remote Earth Stations.

There is a video animation at the link showing the launch of their imagined rocket. It is worth watching because its almost cartoon quality indicates how far they probably have to travel to make this project happen.

Proton rolled to launchpad for June 8 launch

11:01 am

After a pause in launches lasting one day short of a full year, Russia has rolled its Proton rocket to the launchpad for a hoped-for June 8 launch of a commercial communications satellite.

The article provides a nice overview of Russia’s struggles during the past year, attempting to track down the reasons why their rockets were having problems (corruption at the rocket engine factory) and their repeated attempts to get this rocket off the ground.

They hope, if all goes well, to complete seven Proton launches through the end of 2017 in order to clean up their backlog while also demonstrating that they have solved their quality control problems.

India successfully launches its first GSLV Mark 3 rocket

8:59 am

India today successfully launched its most powerful rocket, the GSLV Mark 3, for the first time.

The first orbital launch of India’s Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk.III) marked a milestone in India’s space program, with the more powerful rocket allowing the Indian Space Research Organisation (ISRO) to begin launching heavier payloads aboard its own vehicles – both for spaceflight applications such as communications and in support of the country’s nascent manned space program.

Monday’s launch came two and a half years after the GSLV Mark III’s maiden flight, a successful suborbital test for which only the rocket’s lower stages were live. The test flight, conducted on 18 December 2014, carried a prototype crew capsule and also served to validate the rocket’s design and demonstrate the stage performance and operation of the rocket’s solid-fuel first stage and liquid-fuelled second stage.

This is India’s third launch this year, which amazingly ties them at this moment with Russia. This will change, as Russia hopes to resume Proton launches this week, but the fact both speaks well of India’s growing success in space and Russia’s continuing problems.

Another proposal for dealing with the Outer Space Treaty

10:02 pm

Link here. The author has made an interesting analysis of my earlier essay on this subject, and come up with what I think is a very intriguing and most encouraging idea:

Government establishes a legal framework for enforcing law. So, rather than allow nations to make claims of territory, let us instead allow private enterprises to go to the Moon or elsewhere, stake a claim, and then, to establish a legal framework for resolving any disputes that arise, choose the government under whose legal jurisdiction their claim will reside. No governments would appropriate territory. They would merely be lending their courts to render judgments on legal disputes arising outside their territories. That would seem to satisfy Article 2. This scheme would not require a new Treaty but could probably be implemented via United Nations resolutions. [emphasis in original]

I actually like this, as it puts the power in the hands of the citizens or companies, allowing them to pick the nation to which they wish to align.

What I find most encouraging however is that the subject of the Outer Space Treaty is now becoming a major issue worth discussing, by many others. I have my ideas, others have theirs. Either way, the issues and weaknesses of the treaty are now being debated, and people are proposing solutions. In the fifty years since the treaty was signed it has previously been impossible to generate this much discussion on this issue. (Believe me, I have tried.) That others are now responding and proposing alternative approaches means that maybe the time has finally arrived where this problem will be dealt with.

Arianespace successfully launches two commercial satellites

11:16 pm

Capitalism in space: Arianespace tonight successfully launched two commercial communications satellite with its Ariane 5 rocket.

This is the third launch by the company since it settled its labor problems in French Guiana in late April. Since then they have managed a launch ever two weeks, and at the moment Arianespace and SpaceX are tied for the most launches in 2017 at six. This tie should only last until Saturday when SpaceX hopes to launch a reused Dragon to ISS.

VSS Unity completes fifth glide flight

4:30 pm

Virgin Galactic’s new suborbital ship, VSS Unity, successfully made its fifth unpowered glide test flight today.

VSS Unity’s glide flights have gone well, and as a result, Virgin Galactic is getting ready to transition to the next part of the test campaign, company representatives said. “To that end, as we analyze the data from today’s flight, we will be moving into a period of ground-based activity focused on preparation for fueled, and then powered, flights,” they wrote in the description.

They provided no indication of exactly when those next flights will occur, which considering the company’s past record of failed predictions, is definitely a good thing.
