‘I’ Newspaper: NASA Planning Permanent Return to the Moon

February 12, 2019

Before the deep political stuff, a piece of space news. According to yesterday’s I for 11th February 2019, NASA is planning to go back to the Moon and found permanently manned bases. The article by Clark Mindock, ‘NASA wants to station humans on the Moon’ on page 23 ran

NASA is planning to send astronauts to the Moon again, but this time it wants to keep them there.

The US space agency’s administrator, Jim Bridenstine, called yesterday for “the best and brightest of American industry to help design and develop human lunar landers”, in response to what he said was a clear mandate from President Donald Trump and Congress to once again get astronauts out of Earth’s orbit.

In a post detailing Nasa’s lofty goals – to return astronauts to the Moon, and one day send them to Mars for the first time in human history – Mr Bridenstine said that the US was playing for keeps this time.

“I am thrilled to be talking once more about landing humans on the Moon,” he wrote on the Ozy website.

“To some, saying that we are returning to the Moon implies that we will be doing the same as we did 50 years ago. I want to be clear – that is not our vision.

“We are going to the Moon with innovative new technologies and systems to explore more locations across the surface than we ever thought possible. This time, when we go to the Moon, we will stay.”

Mr Bridenstine said that the ambitious plans would begin later this week, with partners from private industry and elsewhere invited to NASA headquarters in Washington DC to discuss the next generation of lunar landers.

So far, Nasa has already co-operated with nine companies to send cargo tot he Moon, with the ultimate goal being to develop landers that can take astronauts back there.

As a space fan, all I can say is that it’s about time. Way back in the 1970s and 1980s space experts and commenters, like Sir Patrick Moore, the presenter of the Sky At Night, were predicting that we’d have bases on the Moon and elsewhere in solar system by now. But that was before space budgets were drastically cut and NASA instead concentrated on the Space Shuttle. This was supposed to open space up to just about anybody who could afford the cost of a ticket and was in reasonable health. Its crews experienced 3Gs at lift-off, but this was considered to be so low that a 70-year old man could tolerate it. Unfortunately the Shuttle was massively overengineered and the Challenger disaster put the programme on hold while its causes were investigated and corrected. Even then its use remained risky, as we saw a few years ago when one disintegrated during re-entry over America and the programme was subsequently cancelled.

There were plans in the 1990s for a private, commercial return to the Moon, according to Focus Magazine, but that didn’t seem to get anywhere.

My guess is that NASA is finally getting round to putting a permanent human presence on the Moon not just because Trump fancies going back to the glory days of the Cold War space race, but because the EU and the Chinese are also planning the serious exploration of the Moon. A little while ago ESA – the European Space Agency – announced they were planning to put people on the Moon, while last week the Chinese successfully landed a probe on the Moon’s far side. The Chinese are putting such effort into their space programme that the quantum physicist and SF writer, Stephen Baxter, predicted back in the 1990s that the first person on Mars would probably be Chinese sometime in the next decade. Under Reagan, one of the big aerospace conglomerations and think tanks published a report arguing that America needed to develop its space technologies and industries, and move out onto the High Frontier, in order to secure its place as world leader. It’s likely that this is the same thinking behind this announcement by NASA.

As for exploring the next generation of lunar landers, I wonder if they’ll be able to use any data or blueprints remaining from the original lunar modules that landed Armstrong, Aldrin and co all those years ago. After the Apollo programme was cancelled, the massive Saturn 5 rockets were broken up, with the exception of those on display at the Kennedy Space Centre, and the plans destroyed. This has outraged many space scientists like John S. Lewis, the author of Mining the Sky, who compared it to the destruction of Chung He’s fleet by the Chinese eunuchs in the 14th century. Chung He was a Chinese admiral, who led a fleet of ships on an exploratory mission to the outside world, going as far as the Bight of Benin in West Africa. However, when he returned the eunuchs at the imperial court had his fleet destroyed and further exploration banned because they feared that opening the country up to foreign contact would have a destabilizing effect on its society. The result of this was that the country remained isolated and stagnated until it fell prey to foreign colonialism in the 19th century, most famously through the Opium Wars.

Hopefully NASA’s announcement will mark the beginning of a new, serious wave of interplanetary exploration which aims to put people on the Moon and other planets, as space scientists, engineers and SF fans and writers have been dreaming about and working towards since before the great German director Fritz Lang made his epic movie Die Frau im Mond (‘The Woman in the Moon’) about a German moon landing back in the 1920s.

The Saturn Five Variants that Were Never Built

May 4, 2017

And now a little break from the elections. This is a short video from Vintage Space, discussing the variants of the Saturn V moon rockets that were designed, but never built. These new space vehicles were designed to be bigger and better. From what is said about them in the video, it seems the designers adopted a modular approach, or something like it, so that stages and rocket motors could be swapped around and altered to allow the rockets to be customised to suit different missions.

It’s a pity that these awesome machines were scrapped at the end of the Apollo missions. I’ve read letters in Spaceflight, one of the magazines published by the British Interplanetary Society by scientists, who believed that the proper way into space would have been through building Big Dumb Boosters. Although not reusable, they could be mass produced, which would mean they could be constructed for the cost of a battle ship, and bring launch costs down to about $100,000.

Some space scientists are still bitter about the destruction of the Saturn Vs and even the plans for them. They were the only rockets capable of taking people out to the Moon, and potentially further out into the Deep Black. John Lewis in his book, Mining the Sky, on how humanity could expand into space to exploit the rich material and energy resources of the solar system, compares the destruction of the Saturn V to the destruction of Chung He’s fleet. Chung He was a Fifteenth century Chinese explorer, who led an expedition that sailed around the world. One of the places he reached was the Bight of Benin in West Africa. On his return, however, the eunuchs of the imperial court decided that the fleet represented a threat to the stability and order of the Chinese empire. So they destroyed it, thus helping to keep China isolated from the outside world for centuries. The bureaucrats, who ordered the destruction of the Saturn V moon rockets were, in Lewis’ view, guilty of the same kind of thinking.

There are alternative crewed space vehicles under development, and it is believed that the Chinese are planning to send a crewed mission to the Moon, quite apart from the various schemes to land people on Mars.

In the meantime, this video shows some the spacecraft that could have been.
