Discovery of 50km cave raises hopes for human colonisation of moon – The Guardian -19-Oct-2017
Japan’s space agency said it had discovered an enormous cave beneath the lunar surface that could be turned into an exploration base for astronauts.
Using a radar sounder system the orbiter initially found an opening 50 metres wide and 50 metres deep, prompting speculation that there could be a larger hollow.
The chasm, 50km (31 miles) long and 100 metres wide, appears to be structurally sound and its rocks may contain ice or water deposits that could be turned into fuel.
The discovery will boost plans by several countries to send astronauts to the moon almost half a century after the Apollo 11 mission.

Elon Musk Reveals More About Plan to Colonize Mars – Fortune – 15-Oct-2017
Musk clarified that, though he has shared images of vast Martian cities in his presentations on Mars colonization SpaceX isn’t focused on building those cities itself.
They are aiming to build the equivalent of the transcontinental railway.
Musk also reiterated previous claims that SpaceX is designing the new Mars rocket – still code-named BFR which stands to be as safe and reliable as today’s commercial airliners.
Its first scheduled flight will be in 2022.

Mars crews could be at risk from onboard microbes – The Guardian – 4-Oct-2017
Mars500 project simulated a 17 month mission to Mars in a 180sq metre capsule.
Parts of the capsule were rife with microbial life.
Microbial diversity fell over time – could become a problem if only pathogens left.
Space environment could leave humans more susceptible to infection.

COMMENT: unless everyone is dedicated we’ll need a new drug to address rapid muscle loss in low gravity

Longevity will lead to Overpopulation – IEET – 4-Jul-2015
Article by Live Forever Club’s Adrian Cull considers 2 main strategies:
1. prevent the increase in population or
2. find somewhere for the ever growing mass of people to live.
For the 2nd option it was surprising to find that if the world spent 2% of GDP (similar to current defence spending) on space launches we could remove the 75 million people currently being born every year.

Three main hurdles: 1. nowhere in our solar system offers a suitable  environment, 2. will need significant propulsion power, and 3. interstellar dust likely to damage crafts travelling to other suns.
