One flies just within Earth's orbit around the sun the other just outside it allowing the pair to obtain unique measurements of solar wind behaviour.
We can only see this effect from Earth if the two objects are aligned perfectly. Now a team led by Robert Quimby at the University of Tokyo Japan has confirmed the first case of this lensing effect in a type 1a supernova:
which is just 1 per cent as dense as Earth's. Unfortunately rocket-powered landings are out of the question too as the atmosphere is still just thick enough to buffet incoming spacecraft with more turbulence than thrusters can accommodate.
As it falls back to Earth the system will inflate and moments later the parachute will fire.

#Earth raises a plasma shield to battle solar storms Earth can raise shields to protect itself against solar storms.
The discovery confirms a longstanding theory about Earth's magnetic surroundings and offers us a way to keep track of the planet's defences.
Earth doesn't just sit there and take whatever the solar wind gives it it can actually fight back.
Earth is surrounded always by a bubble of magnetism called the magnetosphere which protects us from the bulk of the solar wind a stream of high-energy particles constantly flowing from the sun
. But sometimes the sun's magnetic field lines can directly link up with Earth's in a process called magnetic reconnection which opens up cracks in the magnetosphere.
Charged particles can flow along these lines into Earth's atmosphere leading to dazzling auroras as well as geomagnetic storms that can wreak havoc on navigation systems and power grids.
Gas in Earth's upper atmosphere is ionised by ultraviolet light from the sun and the resulting plasma becomes trapped by magnetic fields in a doughnut-shaped ring around the planet.
For the first time we were able to monitor the entire cycle of this plasma stretching from the atmosphere to the boundary between Earth's magnetic field
when does the Earth decide to protect us? By validating this tool we're now able to figure that out t

The moon is the nearest island in space out from the Earth says Igor Mitrofanov at Russia's Institute for Space Research in Moscow the project scientist for two planned Russian-led rover missions.
As countries develop their space programmes the moon is a natural first foray beyond Earth that allows remote-controlled robots to get their sea legs
and evolution of the moon is to know those of Earth says Tatsuaki Hashimoto of the Japan aerospace exploration agency the lead scientist for a proposed lunar rover called SELENE-2. The moon is thought to have coalesced from the debris of an impact between a Mars-sized world and Earth
It's a part of the Earth says Foing. I call it the eighth continent. Several of the proposed exploration missions are targeting the moon's poles

NASA's LADEE moon orbiter due to launch on 7 september will use laser pulses to exchange high-capacity signals with Earth.
LLCD will beam signals to Earth at 622 megabits per second six times as fast as is currently possible from the moon.

Future Chinese missions could bring lunar samples back to Earth perhaps around 2017 and possibly land people on the moon in the 2020s says Dean Cheng of the Heritage Foundation a think tank in WASHINGTON DC.
But extreme UV radiation coming from space is absorbed by the Earth's atmosphere so it is not observable from the ground says Sawai.

Unfortunately that may be mixed news for seekers of Earth-sized worlds. Kepler was designed to spot transits the periodic dips in a star's brightness indicating that a planet has passed in front of it.
That can help to pinpoint whether it is rocky like Earth or gassy like Jupiter as long as the star's size is known.
That's probably because each granule spans some two dozen times the width of the Earth in a giant star compared to just a fraction of the Earth's diameter in a compact star.
How will that affect the count of Earth-sized worlds? Kepler's principal investigator William Borucki expects the current pool of candidates to shrink.
The method can put several small satellites into orbit around Earth eliminating the need for dedicated launch vehicles and making citizen-science missions like Ardusat more affordable.

which has been orbiting Earth since September 2011. The crew will do one automatic and one manual docking test.
The standard picture is that inside a dust disc grains smaller than a few micrometres will clump together until they grow into rocky bodies up to 10 times the mass of Earth.
For a star like our sun a dusty clump in the same orbit as Earth can grow to about a metre wide.
It will fall back to Earth in about two weeks and disintegrate upon reentering the atmosphere. The dummy contains instruments that will collect data about the launch to be transmitted back to mission managers before re-entry.

it means there is a large time lag in the service, as radio waves take a quarter of a second to make the round trip up to a geosynchronous satellite and back.
