An alien experience!
Exoplanet Kelper 452-b is 60% wider than Earth and approximately 5x as massive so much stronger surface gravity.
This provides for a great workout! For the manly among us this essentially means it will make you much stronger 🙂
For everybody chilling on this Earth cousin, the higher gravity would probably lead to significant body changes long term – e.g. becoming stockier built. This is probably not a plus if you’re already on the stocky side…you may become very short and squat…like a rotund garden gnome 😉
A Familiar Experience
As this world’s sun is roughly the same distance away as on Earth, the light factor would be much the same as on our home-world and Earth plants transported to its cousin-world could photosynthesis the same as on Earth.
So Kelper 452-b is similar to Earth but not the same. Its sun is 6 billion years old whereas our Sun is only 4.5 billion years old. Kelper 452-b’s sun is at a far more energetic life-stage therefore it is hotter. And it is about 10% larger and 20% brighter in the sky. Not bad for the sun tan then 😉
Kelper 452-b completes one orbit every 385 days so it’s year is only about 20 days longer than Earth’s. Pretty much home from home.

“…substantial opportunity for life to arise, should all the necessary ingredients and conditions for life exist on this planet.”

NASA to Mars 2030
"Interest in sending humans to Mars I think has never been higher. We now stand on the precipice of a second opportunity to press forward to what I think is man’s destiny — to step onto another planet." NASA chief Charles Bolden at the Humans 2 Mars Summit at George Washington University. (May 6-8 2013)
Yet the road to Mars is long and challenging, and the difficulties are scientific, technological, political and economic,”
“Sending astronauts to the Red Planet” (as President Barack Obama has directed NASA to do and to land humans on Mars by the 2030s) “will likely require at least three missions: one to launch the crew and the vehicle that will take them to Mars, one to launch the habitat humans will live on at the planet’s surface, and one to launch the vehicle that will lift off from Mars to take the crew home,“ said Doug Cooke, a former NASA associate administrator for the Exploration Systems Mission Directorate who now heads a space consulting firm.
"To me this is one of the biggest challenges," Mike Raftery, director of space station utilization and exploration at Boeing, the primary contractor for NASA’s heavy-lift rocket being developed to go to Mars. "We have to essentially land a launch pad on the surface that’s then ready to launch the crew back to Earth.”
This will be no small challenge as to date, NASA has been unable to land more than 1 metric ton at a time on the surface of Mars — the Curiosity Rover. With a total 200 to 400 metric tons of equipment requiring delivery to the surface of Mars after being launched from Earth at the rate of 40 metric tons per trip, clearly this could prove problematic.
Engineers will have to develop a means to shield the Mars crews from dangerous radiation both en-route and on the surface of the Red Planet where the atmosphere is too thin to shield them as it does on Earth. They will also have to bring their own life-support systems, medicine, food, communications systems and navigation equipment.
"It’s very likely that we’ll send some kind of lander or rover to the site we want to send people to first, to drill a couple meters down to tell us if we have fresh water," said John Grunsfeld, associate administrator for NASA’s science mission directorate. Such a spacecraft could also serve as a beacon to guide the crewed lander down to the chosen spot on Mars.
"We’re going to have to rely on being able to live off the land," said James Reuther of NASA’s Office of the Chief Technologist. "Those will require significant technology investments in order to actually bring that about."
Despite the challenges involved, many NASA and industry experts expressed confidence it can be done. In the words of Artemis Westenberg, president of Explore Mars Inc., the non-profit space advocacy group that organized the conference:
"In the coming days we have the opportunity to write history, to determine the future of humankind. We of Explore Mars give you this platform of this three-day summit. Now all you have to do is tell each other and the world the ‘how’ of getting to Mars.” (via Space.com)
Mars One 2016
The organisers of the Mars One project (a Dutch group, led by Bas Lansdorp, a researcher from the Netherlands with a Masters in Science from Delft University of Technology) think they have the answers to this quandary. They have seemingly jumped ahead of NASA, announcing ambitious plans to, “execute the first fully commercial campaign of human exploration and development of Mars,” and have high hope of establishing the first settlers of a Mars colony by 2023.
By 2016 they intend to send a communications satellite to the Red Planet, following it up with additional time phased flights across succeeding years, before the actual landing of a foundation crew of permanent Mars colonists. The optimistic claim on their website states that:
“Mars One will establish the first human settlement on Mars in 2023. A habitable settlement will be waiting for the settlers when they land.”
Following the establishment of the foundation crew on the Red Planet, an additional group of new settlers will be sent to join them on a regular two-yearly basis, thereby expanding the colony.
Mars One has no shortage of industry support and their suppliers include, ILC Dover, MDA Corporation, Paragon Space Development, SpaceX, Surrey Satellite Technology (SSTL), and Thales Alenia Space.
“SSTL believes that the commercialization of space exploration is vital in order to bring down the costs and schedules. Mars-One is an imaginative venture making use of existing technology and SSTL is highly motivated to support this initiative,” Sir Martin Sweeting, Founder and Executive Chairman of SSTL.
“I believe that the endeavour holds great promise and Paragon is prepared to manufacture and integrate the Mars One life support, thermal control, and space suit systems,” Jane Poynter, President and Chairwoman at Paragon Space Development Corporation
The cost of launching the initial crew of four Martian colonists and landing them on the Red Planet, in addition to the utilisation of the SpaceX Falcon Heavy launcher, will involve costs in the region of $6 billion, according to Mars One. Besides building their environment the colonists will also be tasked with answering questions regarding the on-going mystery of whether life in fact does exist on Mars and also the history of the neighbouring planet.
Astronaut selections (40 in total will be chosen) for the first manned Mars mission have already begun and applications have rolled in, in vast numbers. Potential applicants should however remember; this is a one-way trip! Mars One has no plans and no way of bringing you back! You will never set foot on Earth again…you will never breathe the air of Earth again…and you certainly won’t be able to Skype your friends and family!

Fire in the Sky
Great Solar Storm of 1849
250 years ago fire lit up the skies of our predecessors world, turning night into day, wreaking havoc with the technology of the time. Now, in the closing days of the year 2009 and as we roll inexorably closer to New Year 2010 we stand on a pinnacle between worlds, a centre-point between past and future. As in the year 2349, if humankind still inhabits the Earth, they, the children of the future will see once again that fire that will light up the skies. Because when 500 years of our time has passed the Great Solar Storm of 1849 is set to return to that future world…
This spectacular event was caused by a period of intense solar activity….
London saw curtains of light dancing in the skies above the Houses of Parliament. In Cheshire newsprint could be read by its light. In Manchester people throughout the city had curtains of fire.
· Two massive solar events; Coronal Mass Ejections (CME) sent millions of tonnes of supercharged solar gases hurtling towards Earth at 2,000+ km/sec. Arriving in less than 18 hours they struck with enough force to throw our protective magnetic field into chaotic fits.
· This magnetic disruption caused the readings on worldwide scientific instruments recording changes in Earth’s magnetic field to go completely off their scales. The communication system of the time became inoperable.
Night became day in the Northern Hemisphere and the resulting lights in the sky were reported by half the world as far South as the Caribbean and Venezuela……
The Coronal Mass Ejections may have been triggered by flare events resulting in a massive ejection of plasma from the Sun’s atmosphere (Corona)
Since we live in an electronic society the effects on modern society would be disastrous.
· Satellites would fail and potentially fall out of orbit
Following the Solar Storm the magnetic field was so distorted and overwhelmed that the Northern Lights appeared all over the planet. This happens every 500 years or so. Next Storm expected in the year 2349.
