Unknown new British company will fly space tourists in five years

9:03 am

Private vaporware: A new and previously completely unknown British rocket company, Starchaser, has claimed today that it will be flying tourists into space within three to five years.

How do I know this is vaporware and won’t happen? Besides the fact that I’ve never heard of this company before and that the story above includes a lot of fishy details (such as the head of the company has apparently most spent his time building large model rockets), there was this one quote:

The flight will only take an hour and will see the rocket reach around 330,000ft – ten times the average cruising altitude for an aeroplane flight.

An hour is too short for an orbital flight, and is much too long for a suborbital flight at 330,000 feet. In other words, something here is just not right. Regardless, I hope my cynicism here turns out to be wrong, and this company joins the new competition to lower costs into space.

Russia reveals its proposed new cargo spacecraft

8:57 am

Government vaporware: In an effort to save money Russian engineers have designed a new cargo spacecraft to replace the Progress freighter.

Faced with latest economic problems, and the need to reduce the number of Progress cargo launches, Russia’s space agency Roskosmos made plans to cut the permanent crew of ISS cosmonauts from three to two people. However the full international crew on the ISS is supposed to include six people with half of it reserved for Russia.

To resolve this supply problem, Roskosmos ordered RKK Energia, its key contractor responsible for human spaceflight, to prepare a preliminary design of a bigger cargo ship by the end of this month. Engineers quickly put together this proposal that would combine off-the-shelf hardware with new technology. … The most important new feature of the proposed cargo ship will be the six-tank cluster to carry more than 1.8 tons of propellant to the station. It will simultaneously serve as a tanker for the space station while also feeding the ship’s own propulsion system. As a result, the new design provides significant mass savings in comparison to the current Progress ships, which need two separate sets of tanks for refueling and maneuvering.

The main engine for the new cargo ship will be borrowed from an existing satellite. Meanwhile, 28 small thrusters for orbit correction and maneuvering will be copied practically unchanged from the Progress.

They hope to fly this new freighter by 2020. I’m willing to bet anyone that this won’t happen.

The world’s longest and highest glass-bottomed bridge

8:53 am

Link here. Lots of great pictures of this new pedestrian bridge in China, including one of a reporter trying (and failing) to use a sledge hammer to break the glass.

China’s economy might have a lot of holes and might face collapse, as many experts have been telling me for years, but at the same time they seem to be successfully harnessing the success they’ve had in the past few decades to get very creative. That creativity suggests to me the collapse is not guaranteed, and will not be as severe as predicted.

More reasons why I don’t use Windows

3:07 pm

A close look at Microsoft’s track record in rolling out Windows 10 suggests the company “blatently disregards user choice and privacy.”

After describing the numerous horror stories of how Microsoft forced Windows 10 updates on people against their will, there was this:

The trouble with Windows 10 doesn’t end with forcing users to download the operating system. Windows 10 sends an unprecedented amount of usage data back to Microsoft, particularly if users opt in to “personalize” the software using the OS assistant called Cortana. Here’s a non-exhaustive list of data sent back: location data, text input, voice input, touch input, webpages you visit, and telemetry data regarding your general usage of your computer, including which programs you run and for how long.

You do have to opt-in to Cortana, but even if you don’t, your privacy is still not secure:

And while users can disable some of these settings, it is not a guarantee that your computer will stop talking to Microsoft’s servers. A significant issue is the telemetry data the company receives. While Microsoft insists that it aggregates and anonymizes this data, it hasn’t explained just how it does so. Microsoft also won’t say how long this data is retained, instead providing only general timeframes. Worse yet, unless you’re an enterprise user, no matter what, you have to share at least some of this telemetry data with Microsoft and there’s no way to opt-out of it. [emphasis in original]

It is once again time for people to consider alternatives. Here again are the links to James Stephens’ series on Behind the Black for Getting and Installing Linux:

Lots of launches

9:52 am

The competition heats up: The next few weeks will be a busy period for rocket launches:

SpaceX’s September 3 launch is part of their effort to ramp up their launch rate and get 18 Falcon 9 launches in 2016. So far they have completed 8 launches.

The September 8 launch will be the United States first sample return mission to an asteroid, Bennu, which also happens to be an asteroid that could possibly impact the Earth at some time in the future.

The September 10 launch will be another test flight of India’s more powerful Geosynchronous Satellite Launch Vehicle, aimed at competing for launch business against SpaceX, ULA, and Arianespace.

There’s more beyond this. A lot is scheduled for this fall.

SpaceX to up its purchase of carbon fiber?

8:52 am

The competition heats up: A Japanese supplier of carbon fiber materials has announced that it and SpaceX are negotiating a multi-year deal worth possibly as much as $3 billion.

The multiyear deal with Tesla founder Elon Musk’s 14-year-old venture is estimated to be worth 200 billion yen to 300 billion yen ($1.99 billion to $2.98 billion) in total. The two sides are aiming to finalize the agreement this fall after hammering out prices, time frames and other terms. SpaceX aims to hold down expenses by re-using rockets and spacecraft. Originally, the company made rockets mostly out of aluminum to keep costs low, using carbon fiber only for a few parts, such as connecting joints.

The U.S. company said in a statement, “Toray is one of a number of suppliers we work with to meet our carbon fiber needs for Falcon rocket and Dragon spacecraft production, and we haven’t announced any new agreements at this time. As our business continues to grow, the amount of carbon fiber we use may continue to grow.”[emphasis mine]

The deal is not yet final, but the highlighted language above suggests to me that, based on SpaceX’s engineering tests of its recovered first stages, it has decided it is worthwhile replacing aluminum with carbon fiber for many more of its rocket parts. The fiber might cost more, but if the first stage is going to be reused, the cost can be distributed over several launches. And because carbon fiber is lighter than aluminum, it will allow their rockets to launch a larger payload.
