Moon Express Lander: From Moon Express

Naveen Jain's startup, Moon Express, is a contestant in Google's Lunar X-Prize competition. They made the news recently with a little writeup in Fortune. It's a short little, 'imagine the possibilities piece' which some may find interesting. In the article Jain talks briefly about his aspirations for Moon Express. The chief points of interest for me are mining the moon for Helium-3 or precious metals such as platinum. There is also a little bit about storing your DNA on the moon for $50, which is a neat, albeit cheeky, idea.

Depending on how the Helium-3 is deposited on the moon, mining this material may be a much bigger challenge than Jain wants to undertake. If the deposits are uniform across the surface, they are likely to be very low density deposits. This means that lots and lots of lunar soil would need to be mined to generate small supplies of Helium-3. I don't remember the exact numbers and estimations for these deposits.

Mining precious metals seems like a better bet. The article specifically mentions platinum. If I were mining the moon I would be checking the market prices and lunar distribution of rare-earth minerals, too.


A Nation of Places Worth Caring About

Features: Current EventsInstitutions: Ted TalksPeople: James Howard KunstlerFree Tagging: architecture, urban planning

In this delightful TED talk, James Kunstler lays out a strong argument against the urban and suburban planning of post World War II America. He goes on to make a few recommendations for improving the use of urban space in America. Improvements which, he says, are necessary in the face of current global uncertainties.

This is a great presentation, a must watch.


Visible Light Cloaking with Carbon-Nanotube Sheets

A sheet of carbon nanotubes is heated to produce the mirage like effect seen in the video. This work is being done by Ali Aliev of the University of Texas. I wonder what, exactly, is meant by 'sheets of carbon nanotubes'. Is it 'strands', or actual sheets. Incidentally someone has made 3ft by 6ft (~1m x 3m) sheets from carbon nanotubes.


Eyes turn to Fermi Lab

Following the announcement of apparently faster than light neutrinos from CERN, eyes have turned towards one of the two labs in the world which can recreate the neutrino experiment, Fermi Lab outside of Chicago. It turns out that they are about to shut down the resident atom smasher, the Tevatron.


Space X Developing Reusable Rocket

Features: Current EventsCritical Path Innovation: Private Space TravelInstitutions: Space X

A rocket costs about $50 million. The fuel for a single launch costs about $200,000. A great way to save money is to keep the rocket after each launch. People realized this a while ago. The space shuttle was an attempt to move in the direction of reusable space craft. Now Space X is making some noise on the reusable craft scene. They recently announced that they will start attempting to develop a reusable launch platform.

Their announcement comes complete with an animation that is impressive for it's technological vision and the quality of animation itself.


49 years ago: Kennedy at Rice University

Forty-nine years ago, on Sept 12, 1962, John F. Kennedy spoke at Rice University giving us the bold words, 'We choose to go to the moon. We choose to go to the moon in this decade and do the other things; not because they are easy, but because they are hard.'

In this same speech he also said, '‎This country of the United States was not built by those who waited and rested and wished to look behind them. This country was conquered by those who moved forward.'

This is the full speech, take 17 minutes of your day to be inspired.


DRACO Flexible Anti-Viral Drug

DRACO treatment of Rhinovirus and Dengue hemorrhagic fever

From MIT's Lincoln Laboratory comes a new drug called DRACO (Double-stranded RNA Activated Caspase Oligomerizers). Apparently DRACO is able to successfully treat 'nearly any viral infection'. This is accomplished because DRACO targets cells which have a type of RNA (double stranded RNA, dsRNA) which is only found in cells infected with a virus.

To date this anti-viral drug has been tested to be successful against 15 different types of viruses.


Moon Exploration Presentation

This slideshow presentation gives some compelling reasons why we should aim to return to the moon. Namely exploration and science. Shackleford's exploration of Antarctica gets some attention, especially in terms of the unexpected scientific advances that the exploration provoked. Also, this is a well put together group of slides -- these are not your typical bullet point list of 'talking points' that end up being the only existing notes for the speech. These look like real talking points.


Space X -- Falcon Heavy

SpaceX Falcon Heavy

SpaceX, Elon Musk's launch company has developed a rocket called the 'Falcon Heavy'. It can deliver a payload of 53,000kg (117,000 lbs) to low earth orbit. This is twice the payload of the retiring space shuttle. The total cost for a 2013 launch is $80-125 million, or $1509 - $2358 per kg ($683 - 1068 per lb). This represents a significant reduction in launch costs from 2007 when a study by The Tauri Group found that the average launch cost was $21,000/kg.

Shimizu Construction's Luna Ring Concept

While poking through Educated Earth I saw the video presentation from Shimizu Construction. They have a 'dream project' wherein they would build a ring of solar panels around the moon. This ring of solar panels would then beam the electricity back to earth using lasers and microwave beams.

Upon visiting their website, I notice that they also have a number of other 'dream projects'. These include floating pyramid cities, space hotels, and a desert 'aqua net' (lakes in the desert).

Fantastic! I want to have a few glasses of saki with these guys.


Top Gear Test Drives the Moon Buggy

Here's a nice piece from the folks at Top Gear, the TV show from Britain. They drive the buggy around, and even get to try on the space suits which double as an exit hatch. There's even a nice bit of nostalgia about watching the first people tool around on the moon in the 60's.


Water powered Space Flight

Features: Current EventsCritical Path Innovation: Propulsion, FuelsPeople: Brian McConnellFree Tagging: Electrothermal
Water Powered Space Ship Concept (Robert Becker)

From what I can gather, a gent named Brian McConnell put together this neat idea for a water powered space craft. The craft would be propelled with Electrothermal engines. These engines would be powered by large solar panels on the craft. The engines will then super heat water and vent the vapor into space in order to produce thrust. The Electrothermal engines are said to be very efficient.

Obviously, this would require a lot of water. The craft itself, however, is designed like a giant water tank. There are several habitable modules on the craft, and they are all surrounded by water. This would provide the inhabitants with some protection against radiation. It would also provide them with plenty of water for drinking and showers.

One trouble with this idea is getting the massive amounts of water needed into space. The article claims that water could be mined from the moon or mars in order to make this happen.


Handling Very Viscous or Non-Newtonian Fluids

Features: Current EventsInstitutions: Furukawa Kikou

The device in the video can pick up very viscous fluids. I'm not actually sure of the real classification of the blobs in the video - viscous, non-newtonian, gel or something else. Either way, the machine picks these things up without changing the borders of the blob with respect to the surface. It is mesmerizing.
