Another Vostochny manager on trial for embezzlement

8:19 am

The Russians are prosecuting another manager at Vostochny for stealing more than $10 million.

[O]ut of 765 million rubles ($13 million) allocated under the contract with Federal State Unitary Enterprise Spetsstroytekhnologii, Tolstikov had only 100 million rubles ($1.7 million) left. The rest, according to him, he spent for construction trailers for workers.

It is amazing anything has been built at Vostochny. This case is in addition to the more than half dozen other embezzlement cases totaling almost $200 million, a very significant amount of money in Russia as well as a significant portion of the spaceport’s entire construction budget.

MIT redwood forest design wins 2017 Mars City Design competition

7:52 am

A MIT design for an early Martian colony based on underground habitats topped by geodesic domes filled with redwood forests has won the 2017 Mars City Design competition.

At first glance, the MIT habitats don’t look very tree-like. They look more like giant glass balls sitting on the Martian plains, each housing 50 people. But, like real trees, much of the habitat is below the surface in the form of intricate tunnels that connect the spheres and provide protection from cold, radiation, micrometeorites, and other surface hazards. “On Mars, our city will physically and functionally mimic a forest, using local Martian resources such as ice and water, regolith or soil, and sun to support life,” says Sumini. “Designing a forest also symbolizes the potential for outward growth as nature spreads across the Martian landscape. Each tree habitat incorporates a branching structural system and an inflated membrane enclosure, anchored by tunneling roots. The design of a habitat can be generated using a computational form-finding and structural optimization workflow developed by the team. The design workflow is parametric, which means that each habitat is unique and contributes to a diverse forest of urban spaces.”

The habitats rely heavily on water, but not just for drinking, agriculture, or public fountains. It’s a key ingredient in making the domes habitable. “Every tree habitat in Redwood Forest will collect energy from the sun and use it to process and transport the water throughout the tree, and every tree is designed as a water-rich environment,” says Department of Aeronautics and Astronautics doctoral student George Lordos. “Water fills the soft cells inside the dome providing protection from radiation, helps manage heat loads, and supplies hydroponic farms for growing fish and greens. Solar panels produce energy to split the stored water for the production of rocket fuel, oxygen, and for charging hydrogen fuel cells, which are necessary to power long-range vehicles as well as provide backup energy storage in case of dust storms.”

This is a very nice concept, and an excellent approach. While they appear to assume the underground habitats will be artificially dug, there is no reason the tree domes can’t be placed over a Martian pit entrance to a cave.

SpaceX aims for December 29 launch of Falcon Heavy

5:58 pm

Capitalism in space: SpaceX has set a date for the first Falcon Heavy launch as no earlier than December 29.

They hope to be able to do a number of dress rehearsal countdowns prior to actual launch, which is what makes this schedule somewhat tentative.

While SpaceX has ample experience lighting all nine engines of the Falcon 9 simultaneously, with every Falcon 9 going through a full duration hot fire at McGregor followed by a static fire on the launch pad before all nine engines are lit a third time for launch, no company in the U.S. rocket industry has experience lighting 27 engines at the same time.

While each of the three Falcon Heavy debut cores – two flight-proven cores for the side-mounted boosters (boosters B1023 and B1025) and a new core for the central core (booster B1033) – have undergone hot fire testing at McGregor, they were all fired separately because the Texas test site is not built to accommodate three cores at the same time.

This means SpaceX will not gain a full understanding of how all 27 engines light until the more-crucial-than-usual static fire at LC-39A at Kennedy.

Users blocked from files by Google Docs

9:19 am

Reason 4,320,333 why I do not use Google: Some users of Google Docs yesterday were blocked by the company from their files because of “terms of service violations.”

In response to some of these reports, a Google employee tweeted that the team handling Google Docs was looking into the matter. Later Tuesday, Google said in a statement that it had “made a code push that incorrectly flagged a small percentage of Google Docs as abusive, which caused those documents to be automatically blocked. A fix is in place and all users should have full access to their docs.”

Although the error appeared to be a technical glitch, the fact that Google is capable of identifying “bad” Google Docs at all is a reminder: Much of what you upload, receive or type to Google is monitored. While many people may be aware that Gmail scans your emails — for instance, so that its smart-reply feature can figure out what responses to suggest — this policy extends to other Google products, too.

Here’s what this story reveals: Google monitors the content of the files that people store on Google Docs. Google has also developed software that can decide if some of that content is acceptable or unacceptable, to Google. Google can then block access to those supposedly private files, thus giving it the power to silence the work of anyone the company doesn’t like.

Sounds peachy-keen, doesn’t it?
