Saturn Spacecraft Returns to the Realm of Icy Moons.
A dual view of Saturn's icy moon Rhea marks the return of NASA's Cassini
spacecraft to the realm of the planet's icy satellites. This follows
nearly two years during which the spacecraft's orbits carried it high
above the planet's poles. Those paths limited the mission's ability to
encounter the moons, apart from regular flybys of Titan. Cassini's orbit
will remain nearly equatorial for the remainder of 2015, during which
the spacecraft will have four close encounters with Titan, two with
Dione and three with the geyser-moon, Enceladus.

Space to Ground this week :)
NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station.
One-Year Crew Welcomed Aboard Space Station.
NASA astronaut Scott Kelly and Mikhail Kornienko and Gennady Padalka of the Russian Federal Space Agency (Roscosmos) joined their Expedition 43 crewmates when the hatches between the Soyuz TMA-16M spacecraft and the International Space Station opened at 11:33 p.m. EDT Friday, March 27. Kelly and Kornienko will spend about a year on the space station to better understand how the human body reacts and adapts to the harsh environment of space.

Crew Ready to Launch For a Year in Space.
Two humans are getting ready to say farewell to Earth for nearly 12
months. Later today, NASA astronaut Scott Kelly and Russian cosmonauts
Mikhail Kornienko and Gennady Padalka will launch to the International
Space Station. Kelly and Kornienko will begin a one-year mission in
space, testing the limits of human research, space exploration and the
human spirit.

Fly over Mars in 3D
Among the most interesting landforms on Mars are features referred to
as ‘chaotic terrain’. Dozens or even hundreds of isolated mountains up
to 2000 m high are scattered in these extensive regions. Seen from
orbit, they form a bizarre, chaotic pattern. Such terrains are found
over a large area to both the west and east of Valles Marineris, the
largest canyon in the Solar System. Hydraotes Chaos, showcased in this
video, is a typical example of this type of landscape.
The data
used to generate these images and the simulated flyover were acquired
with the High Resolution Stereo Camera on ESA’s Mars Express orbiter.
This anaglyph movie can be viewed using stereoscopic glasses with red–green or red–blue filters.
Mars Express
From the highest volcano to the deepest canyon, from impact craters
to ancient river beds and lava flows, this showcase of images from ESA’s
Mars Express takes you on an unforgettable journey across the Red
Planet.
Mars Express was launched on 2 June 2003 and arrived at Mars six-and-a-half months later. It has since orbited the planet nearly 12 500 times, providing scientists with unprecedented images and data collected by its suite of scientific instruments.
The data have been used to create an almost global digital topographic model of the surface, providing a unique visualisation and enabling researchers to acquire new and surprising information about the evolution of the Red Planet.
The images in this movie were taken by the High Resolution Stereo Camera and the video was released by the DLR German Aerospace Center as part of the ten years of Mars Express celebrations in June 2013. The music has been created by Stephan Elgner of DLR’s Mars Express planetary cartography team. DLR developed and is operating the stereo camera.

Asteroid Redirect Mission
NASA announced the next step in the plan to retrieve an asteroid boulder
from a near-Earth asteroid and redirect it into a stable orbit around
the moon to carry out human exploration missions, all in support of
advancing the nation's journey to Mars. For NASA’s Asteroid Redirect
Mission (ARM), a robotic spacecraft will capture a boulder from the
surface of an asteroid for exploration by astronauts in the mid-2020s to
test a number of new capabilities needed for future human expeditions
to deep space, including to Mars. This animation illustrates the crewed
part of ARM, showing how astronauts will travel to the asteroid using
NASA’s Space Launch System (SLS) rocket and the Orion spacecraft,
investigate the boulder and return a sample of the asteroid back to
Earth.

Help the New Horizons team put names on the maps of Pluto and Charon!
Working with the International Astronomical Union , the New Horizons team plans to assign names to the features on the maps of Pluto and its large moon Charon, once we have seen them in sharp detail this summer. At this site, you can suggest your ideas for names and vote for your favorites. The team will use your best ideas in their proposal to the IAU.
The ballot will close on April 7, 2015.
I have nominated Discovery to be added to the ballot.
Motivation: Space Shuttle Discovery.Over 27 years of service it launched and landed 39 times, gathering more spaceflights than any other spacecraft to date.
Please vote for Discovery.

The Expedition 43 Soyuz Spacecraft Is Prepared for Launch.
At the Baikonur Cosmodrome in Kazakhstan, the Soyuz TMA-16M spacecraft
was mated to its Soyuz booster rocket March 24 as preparations continued
for the launch of Expedition 43 Soyuz Commander Gennady Padalka and
Flight Engineer Mikhail Kornienko of the Russian Federal Space Agency
(Roscosmos) and NASA Flight Engineer Scott Kelly on March 27 U.S. time
(March 28, Kazakh time) to the International Space Station. Kelly and
Kornienko will spend a year aboard the station conducting research on
the long duration effect of space travel on the human body.

NASA's Curiosity Rover Finds Biologically Useful Nitrogen on Mars.
A team using the Sample Analysis at Mars (SAM) instrument suite aboard
NASA's Curiosity rover has made the first detection of nitrogen on the
surface of Mars from release during heating of Martian sediments. The
nitrogen was detected in the form of nitric oxide, and could be released
from the breakdown of nitrates during heating. Nitrates are a class of
molecules that contain nitrogen in a form that can be used by living
organisms. The discovery adds to the evidence that ancient Mars was
habitable for life.

Shock Wave.
Rocket launches have always been a tricky business, especially in the
early days of the space program. Roy Tharpe, who grew up with the space
program, was really too close to a launch in 1960.
Scientists at Large Hadron Collider hope to make contact with PARALLEL UNIVERSE in days
If successful a completely new universe will be revealed – rewriting not only the physics books but the philosophy books too.
It is even possible that gravity from our own universe may ‘leak’ into this parallel universe, scientists at the LHC say.
The experiment is sure to inflame alarmist critics of the LHC, many of whom initially warned the high energy particle collider would spell the end of our universe with the creation a black hole of its own.
But so far Geneva remains intact and comfortably outside the event horizon.
Indeed the LHC has been spectacularly successful. First scientists proved the existence of the elusive Higgs boson ‘God particle’ - a key building block of the universe - and it is seemingly well on the way to nailing ‘dark matter’ - a previously undetectable theoretical possibility that is now thought to make up the majority of matter in the universe.
But next week’s experiment is considered to be a game changer.
Mir Faizal, one of the three-strong team of physicists behind the experiment, said: “Just as many parallel sheets of paper, which are two dimensional objects [breadth and length] can exist in a third dimension [height], parallel universes can also exist in higher dimensions.
“We predict that gravity can leak into extra dimensions, and if it does, then miniature black holes can be produced at the LHC.
"Normally, when people think of the multiverse, they think of the many-worlds interpretation of quantum mechanics, where every possibility is actualised.
"This cannot be tested and so it is philosophy and not science.
“This is not what we mean by parallel universes. What we mean is real universes in extra dimensions.
“We have calculated the energy at which we expect to detect these mini black holes in ‘gravity's rainbow’ [a new scientific theory].
“If we do detect mini black holes at this energy, then we will know that both gravity's rainbow and extra dimensions are correct."
When the LHC is fired up the energy is measured in Tera electron volts – a TeV is 1,000,000,000,000, or one trillion, electron Volts
So far, the LHC has searched for mini black holes at energy levels below 5.3 TeV.
But the latest study says this is too low.
Instead, the model predicts that black holes may form at energy levels of at least 9.5 TeV in six dimensions and 11.9 TeV in 10 dimensions.
