Astronauts DNA in space changed by an astonishing 7%
Scott and Mark Kelly are twins and both work at NASA. They are part of an experiment to test the influence of space-travel on the human mind and body. Scott Kelly was onboard the ISS (International Space Station) for one year and after his return, scientists found something very unusual. His DNA was not the same at all anymore but has changed by an astonishing 7%. Many researchers are now analyzing this anomaly in great detail and NASA will release a summary-paper sometime this spring.

Why is there this huge increase of evolutionrate since only a few thousand years ago in humanity? Could this mean that (our) dna was originaly created or manipulated in zero gravity? What happened a few thousand years ago that accelerated human evolution by a factor of 100 compared to all previous generations?
The 15,000th near-Earth asteroid discovered is designated 2016 TB57. It was discovered on Oct. 13, 2016, by observers at the Mount Lemmon Survey, an element of the NASA-funded Catalina Sky Survey in Tucson, Arizona. Credit: NASA/JPL-Caltech
The number of discovered near-Earth asteroids (NEAs) now tops 15,000, with an average of 30 new discoveries added each week. The number of discovered near-Earth asteroids (NEAs) now tops 15,000, with an average of 30 new discoveries added each week. This milestone marks a 50 percent increase in the number of known NEAs since 2013, when discoveries reached 10,000 in August of that year. Surveys funded by NASA’s Near Earth Object (NEO) Observations Program (NEOs include both asteroids and comets) account for more than 95 percent of discoveries so far. The 15,000th near-Earth asteroid is designated 2016 TB57. 2016 TB57 is a rather small asteroid — about 50 to 115 feet (16 to 36 meters) in size — that will come closest to Earth on Oct. 31 at just beyond five times the distance of the moon. It will safely pass Earth. Read more
Intelligent Robots might be the best possibility to explore deep space in search of extraterrestrials. Credit: NASA
If you’ve seen at least one other episode of the Guide to Space, you know I’m obsessed about the Fermi Paradox. This idea that the Universe is big and old, and should be teeming with life. And yet, we have no evidence that it exists out there. We wonder, where are all the aliens?
As we’ve demonstrated here in our own corner of the galaxy, it’s not our weak fleshy bodies that will be doing the hard work of exploring the Solar System, and eventually the galaxy, it’ll be the robots. Read more
Jupiter’ s Moon Europa may potentially harbor Life in the Solar System. Credit: NASA/ESA/W. Sparks (STScI)/USGS Astrogeology Science Center
Astronomers using NASA’s Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter’s moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes. The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean without having to drill through miles of ice. “Europa’s ocean is considered to be one of the most promising places that could potentially harbor life in the solar system,” said Geoff Yoder, acting associate administrator for NASA’s Science Mission Directorate in Washington. “These plumes, if they do indeed exist, may provide another way to sample Europa’s subsurface.” Read more
Cassini on its fly through the icy Plumes of Saturn’ s Moon Enceladus.
As NASA’ s Orbiter Cassini flew through Enceladus’s plumes a handful of times in the past 11 years, its instruments were flooded with hydrogen molecules, which are a possible smoking gun for hydrothermal vents in the oceans. If confirmed, those vents would have major implications for life beneath the ice. But it’s unclear whether the hydrogen molecules came from Enceladus or from Cassini itself. That’s because when ice grains in the plumes smack into Cassini’s instruments they break apart, like insects on a car windshield. “They are smashing so fast that they can actually chip the windshield and form tiny craters,” says Bouquet. This releases titanium into Cassini’s instruments, which steals oxygen from the icy water to release hydrogen molecules. Read more
Asteroid “Bennu” may cause great Damage, Nasa is preparing a Space Probe to analyse this Asteroid.
An asteroid named Bennu which can be seen from Earth as it crosses our orbit every six years could potentially cause ‘Immense Suffering And Death’, and NASA is planning to build a space probe in order to collect rock samples from the Asteroid in fears it may collide with our planet.
The asteroid which is around 500 meters in diameters and traveling around the sun at 63,000 miles-per-hor will pass between the Earth and the moon in the year 2135. Read moreThe Times Article
