NASA releases new details on next SLS rockets


NASA is fine-tuning its design for the new Space Launch System (SLS) that will send astronauts to the moon, asteroids and possibly Mars. Basically there will be three main types of rocket, the Block 1, Block 1A and Block 2. Block 1A and Block 2 will both have a crewed and a cargo variant, so that's a total of 5 models. The most important difference with what was announced last September is that the main core stage will now have four or five RS-25D/E Space Shuttle Main Engines (SSME) instead of three.

Black Rock City 2015

'Biohazard' city plan


With all the mess surrounding the ticket sales for this year's Burning Man (for those who don't know, demand largely outstripped supply, and the event sold out its 57,000 tickets, leaving tens of thousands of burners without tickets), I started working on ideas about how to enlarge Black Rock City to accommodate more people. The Burning Man Organization (BORG) is trying to get the Bureau of Land Management (BLM, the federal agency that regulates the public land where Burning Man takes place) to allow them to slowly increase the population from its current cap of 55,000 people to 70,000 in 2016.

Cité de l'Espace

Ariane 5 rocket

During my last visit to France, I visited the Cité de l'Espace in Toulouse, space capital of Europe. The Cité de l'Espace (City of Space) is the european equivalent of the Kenedy Space Center's visitor complex. In addition to numerous interactive exhibits revolving around space exploration, they have a bunch of real space hardware on display, including a Soyuz spaceship and a mockup of the Russian Mir space station that was once used to train astronauts.

Ohm Sport XS750 Electric Bike Test Ride


Back in November I had the opportunity to try a Ohm Sport XS750 electric bicycle for a day, so I though I'd post a review about it. The day long test ride was graciously offered to me by The New Wheel, a cool electric bike retailer in North Beach. So on a sunny Sunday morning, I embarked upon a 30 mile long ride around San Francisco.

Cesar Chavez Boulevard Improvements


For those wondering what that mess is all about on Cesar Chavez Boulevard in San Francisco, here is the lowdown: They are in the process of replacing a giant 8 feet diameter sewer pipe that runs under the whole length of Cesar Chavez Blvd, from Guerrero Street to the 101 freeway, and also under Valencia Street between Chavez and Mission St (where the Burger King is) as well as under several adjacent streets. So what we see right now around Harrison Street is just the beginning! Once they are done with the underground work, Cesar Chavez blvd will be redesigned, with an addition of bike lanes and a median, plus trees on both sides.

Chinese complete their first space docking manoeuvre


After successfully sending their first man in space in 2003 with Shenzhou-5, and executing their first EVA (Extra-Vehicular Activity) in 2008 with Shenzhou-7, this week the unmanned Chinese spacecraft Shenzhou-8 successfully docked with the TianGong-1 space module, a first for the Chinese Space Program.

NASA's Next Manned Mission to an Asteroid


Now that the Space Launch System program is officially on its tracks, lets take a look at what NASA plans to do with the giant rocket. After the first couple of test flights (including a manned fly-by around the moon somewhere between 2017 and 2021), the first big objective is to send 4 astronauts to a 6 month trip to a Near Earth Object (NEO). The mission would be called 'Plymouth Rock'.
