Delta IV rocket put into orbit a satellite for the US military

United Launch Alliance Company successfully conducted the launch of a rocket Delta IV, which brought with it the WGS-9 satellite for military use. 

A start was made from Cape Canaveral, located in Florida.

Ariane-5 led 2 satellites into orbit

July 25 this year at 23:54 MSK to launch space complex ELA-3 launch vehicle launched from Kourou Ariane-5 with satellites Alphasat (Inmarsat XL) and INSAT-3D.

After 2:25 minutes after the launch rocket boosters separated at 3:18 min folded fairing / TD / 9 minutes separated the first stage, after 27 minutes, the spacecraft Alphasat separated from the 2nd stage of the launch, and by 29 th INSAT-3D. Both satellites successfully uncovered the solar panels / SB /.

The orbit of the ISS has been raised by about 1 kilometer

The rectification of the orbit of the International Space Station to avoid a impact with debris U.S. satellite saints held on November 1.

The experts at NASA and the Russian Mission Control Center said they used to contrive the engine docked cargo ship.

Earlier in the Mission Control Center said that the threat of a collision with debris ISS no American satellite. 

Dragon private space freighter successfully entered orbit term

The U.S. ship company SpaceX Dragon, the first space freighter urban by a private company launched from Cape Canaveral, Florida, successfully separated the Falcon 9 booster rocket, entered into an intermediate orbit prior to approaching Space Station (ISS) and solar panels deployed, NASA reported on its website that broadcast the event online.

The launch, postponed several times, finally came at 7.44 GMT on Tuesday. The separation of the propellant occurred after about 10 minutes, and the solar panels are opened shortly thereafter. Two hours after take-off will be launched on-board sensors that allow the freighter to the ISS approach and make the connection but the approach will be initiated only on the third day.

It is an experimental flight, so the ISS Dragon takes just a load of just 520 kilos: some equipment for experiments, notebooks, batteries, clothes and 117 standard food rations for astronauts. In the future, can carry up to six tons to low orbit and bring back some three tons.

Originally, SpaceX planned to launch the spacecraft on Saturday, May 19, but returned to cancel, by excess pressure in one of nine propellant rocket motors, when the countdown to the launch was over.

In 2006, NASA launched a program that encourages private projects of ships capable of transporting cargo to the orbit and the ISS. SpaceX took four years to develop its Dragon spacecraft in December 2010 made the first flight into orbit and splashed down in the Pacific. To date, the company invested in the project about 1,200 million dollars. Almost a third of this amount was funded by NASA.

Every planet must orbit around a star

In recent times the wandering planets, which is the name often these unique worlds without star have gone from a rarity bordering on the impossible to be an unexpectedly abundant class of planets.

 Fresh investigate now provide an new revelation: Not only are there no star planets, bound only to its galaxy, but even without galaxy may have planets. These amazing worlds, formed within a galaxy may leave due to move at a colossal speed, and could make the trip alone or with their star.

ON THE MOON THE GRAIL SHIPS ARRIVED

It is the mission GRAIL (Gravity Recovery and Interior Laboratory), which aquaculture the crust and the core mole to discern its structure."Our team is not going to have a traditional New Year celebration, but I hope to see our two ships safely in lunar orbit, something that gives us all the excitement and the feeling of euphoria that any necesiatría in a work of this kind "said David Lehman, GRAIL project manager at the Jet Propulsion Laboratory (JPL) in Pasadena, California.

The distance from Earth to the Moon is about 402,336 km. At NASA's Apollo missions took them about three days to travel to the moon. Launched from Cape Canaveral on 10 September, the ships GRAIL (Grail in Castilian) have traveled more than 4 million miles to get there.

A collision with an asteroid 2012 DA14 threat to Earth on February 15, 2013

According to this calculations, the orbit of the asteroid with a diameter of between 40 and 95 meters, cross the Earth orbit. Astronomers have calculated that the February 15, 2013, the asteroid will pass only 26 900 kilometers of our planet, which is lower than the orbits of geostationary satellites (about 35,000 kilometers). A recharcher said that 2012 DA14 "belongs" to the regular type asteroids approaching Earth from behind, then or later, in front of him. 

"These are objects that move from time to time near the Earth in fact, they do not go around the earth, but in a coordinate system with two centers (with the Sun and Earth) will be like to turn around Earth, "he quoted. Now it is impossible to predict what will happen in the encounter with Earth in 2012 DA14. "We have to see it, can be farther from the Earth, then closer, even enough to fall to the ground, with some probability that impact the Earth.
