In the same magazine, it mentions Virgin Galactic launching 670 tourists into the cosmos this year! A while ago someone (Tusconmike?) was going to write to Richard Branson for we people on Palin's Travel to be guinea pigs! LOL!

Oh yes! I remember that Sue!

:D

I think it is safer to travel space using a telescope or the Hubble photographs.

What about the one-way mission they're planning to Mars in 2025?!

Exciting, yes and I would love to go (though I'll (hopefully) be 72 by then! Eeeeek!) BUT it is the 'one-way' bit I wouldn't like.

Re: Space travel by suzulu on 19 January 2014 4:44pm

Yes, a bit worrying the 'one-way' bit! Are they trying to cut down the population of Earth? LOL!

Any current space traveller would need to accept any mission might be one way. Although our technology is good a return journey to Mars is outwith our guaranteed bounds of success. Most probes go there and don't come back or of they don't land then go further into the cosmos.
The shortest distance to Mars is 40 million miles and at 1,000 miles per hour it would take 40,000 hours or 4.5 years to get there. I don't know what our best interstellar space speeds are but it looks like only younger astronauts could persevere the conditions of this journey. The probes that have wandered on Mars surface have shown that it is not really worth the visit, being at least 10 times (maybe 100) more inhospitable than our own planet.

Yes I agree with you Ken - after all, even a short trip to the shops could be 'one-way' if one was involved in a fatal car crash!

I am talking about KNOWING for definite that it is a one way trip....

Then there's the logistics of a food supply and facilities to support the crew during the journey. I wouldn't want to be within 20 miles of the loaded rocket when it takes off.

The European Space Agency will hopefully be safely landing a lander (Rosetta/Philae) on a comet which is 300 million miles away and travelling at 40,000 mph at 3 pm this afternoon. The signal indicating success or failure will take 1 hour to get back to us and the progress can be seen on the BBC News channel at that time. For some more details today's Daily Mail has an item on page 19. The comet was discovered by a couple of Russians and is known as 67P in short form.

This bodes well for targeting a collision course asteroid sometime in the future.

I'll be glued to the telly for the next hour or so.
