Are we morally ready to be an interplanetary species?

Apollo 8’s 1968 mission has been compared to that of Artemis 2. Even though Artemis 2 did not orbit the Moon, whereas Apollo 8 observed the lunar surface during 10 lunar orbits, the mission objectives were very similar. Test the spacecraft, propulsion, life support, navigation, avionics, reentry, splashdown and recovery. 

They are similar in other respects. 

1968 was a year of intense violence around the globe.

Students protested against the government policies in Spain (challenging Franco’s oppressive rule), France (protest started at the Sorbonne and escalated to a General Strike), the UK (brutal suppression of civil rights marches initiated a three-decade-long period known as “the Troubles”, and the USSR invaded Czechoslovakia to maintain an authoritarian grip. In the midst of a particularly brutal Vietnam War and widespread rebellion against repressive civil liberties, Martin Luther King and Robert F Kennedy were assassinated.

We, humans, are capable of some incredibly wonderful things and yet, as we have demonstrated many times in the history of our civilisation, many unequalled acts of extreme brutality and destruction.

Today, in 2026 we have war with the suffering and evil it brings in Africa, the Middle East, Europe and beyond.

Tomorrow could be the start of something even worse.

Almost three decades separate Apollo 8 and Artemis 2. 

Classists note another parallel with today’s events. About 2,500 years ago, according to Herodotus (1.53), the Oracle at Delphi told King Croesus of Lydia that if he marched against the Persians, he would destroy a great empire. 

In a 1963 interview, the philosopher C S Lewis feared that “humanity would spread sinful, colonialist behaviours to other planets, rather than constructive or virtuous influence“.

Potentially, as the only intelligent species in the Galaxy, we should be capable of more. Is this the pinnacle of where intelligent life can go? Until we can live in peace with each other, surely we do not have the right to venture out to others?

Astrophotography using Seestar S50 – March 2026

By Gurbir Dated: March 18, 2026 Leave a Comment

As we begin to lose the winter constellations (in the Northern Hemisphere), here are a few pictures of objects that will soon be lost until winter returns..

All photos were captured with the Seestar S50 and with minimal processing. Details of each photo are recorded at the bottom of each picture. To see a larger version, click the icon in the top right of each image.

Beuty of the night sky.

Episode 132 Space Elevator

By Gurbir Dated: March 12, 2026 Leave a Comment

Credit: Dr. Pete Swan

Imagine a giant vertical railway stretching 100,000 km from the equator, somewhere in the Pacific, straight up into space. Instead of expensive, polluting rockets, the space elevator offers a smooth, slow electric ascent to Earth orbit. This “bridge to the stars” connects a floating Earth platform at 36,000 km to a massive counterweight located 64,000 km farther out. It is held taut by the Earth’s rotation.

Space travel is then transformed from a risky adventure into routine cargo shipping. Powered by revolutionary materials such as graphene and innovative laser beams, a space elevator offers a green, affordable gateway to the solar system. Making that a reality is the ambition of the International Space Consortium.

Rob Whielden and Adrian Nixon from the Nixene Journal talk about the final piece of the Space Elevator engineering puzzle – the ultra-strong material needed to make the tether. Both are experts on the unique properties of Graphene. In this interview, recorded at the University of Manchester’s Graphene Engineering and Innovations Centre, we discuss the ongoing journey of a Space Elevator from science fiction to an operational reality. The discussion includes

  • A 100,000 km tether connects Earth to a deep-space apex anchor.
  • Centrifugal force keeps the cable taut like a spinning bucket.
  • Graphene’s extreme tensile strength makes this massive engineering project possible.
  • Electric climbers move cargo affordably, bypassing inefficient, polluting chemical rockets.
  • Laser beams through atmospheric “windows” will likely power the climbers.
  • China aims to build a functioning space elevator by 2045.

Total Solar Eclipse – Spain 12 August 2026

By Gurbir Dated: March 1, 2026 Leave a Comment

For the first time since 1999, a total solar eclipse will be visible from Europe. Although the precise times of the start and the eclipse are known with remarkable precision, the all-important weather is not.

What is a total solar eclipse? By chance, the moon is 200 times smaller but 200 times closer to the Earth than the sun. In the sky, they appear about the same size. At the time of a total solar eclipse, they ARE in exactly the same place in the sky. The Moon blocks out the sun, and if you happen to be in the shadow of the Moon as it falls on the Earth, you get to see one of nature’s most remarkable spectacles.

Of the many online sources, timeanddate.com offers tons of information, including how it will be seen from many places in Spain and the average cloud cover on that date. For many, including me, Spain offers the best prospect of weather in the path of totality lasting 1m 24s from the city of Zaragoza.

This simulation from https://eclipse2026spain.es/ shows the Moon’s shadow passing over Spain.
