MOSCOW – The date of the maiden launch of Russia’s new Angara rocket has been set for June 25, an official with the Russian Space Agency told RIA Novosti Friday.
“The launch is set for June 25, with the 26th as a backup date,” the official said.
He added the rocket would be fired without an orbital payload from the Plesetsk space center, located about 800 kilometers north of Moscow.
The Angara family of rockets, in development since 1995, is planned to be built in light, semi-he [...]
This is not a scene from a sci-fi special effects movie. The green beam of light and red lunar disk are real enough, captured in the early morning hours of April 15. Of course, the reddened lunar disk is easy to explain as the image was taken during this week's total lunar eclipse.
Immersed in shadow, the eclipsed Moon reflects the dimmed reddened light of all the sunsets and sunrises filtering around the edges of planet Earth, seen in silhouette from a lunar perspective. But the green beam o [...]
The diagram compares the planets of our inner solar system to Kepler-186, a five-planet star system about 500 light-years from Earth in the constellation Cygnus. The five planets of Kepler-186 orbit an M dwarf, a star that is is half the size and mass of the sun.
The Kepler-186 system is home to Kepler-186f, the first validated Earth-size planet orbiting a distant star in the habitable zone—a range of distance from a star where liquid water might pool on the planet's surface. The discovery [...]
Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.
While planets have previously been found in the habitable zone, they are all at least 40 percent larger in size than Earth and unders [...]
As work continues at the Cape Canaveral Air Force Station in Florida for Friday’s 3:25 p.m. EDT launch of the SpaceX Falcon 9 rocket and the Dragon cargo craft, the International Space Station’s Expedition 39 crew geared up Thursday for a contingency spacewalk to replace a failed backup computer relay box on the station’s truss. The 2 ½-hour spacewalk is set for Wednesday, April 23, unless SpaceX scrubs its launch attempt Friday, in which case the excursion will move up earlier to Sunday, [...]
The 1,820th flight of a Soyuz launch vehicle was performed on Wednesday, 16 April 2014 from the Baikonur Cosmodrome in Kazakhstan at 20:20 Moscow time (18:20 Paris time).
The EgyptSat-2 satellite was accurately placed on the target orbit. This was the sixth Soyuz family mission in 2014.
The EgyptSat-2 satellite was manufactured in Russia in the framework of the technical and military cooperation between the Russian Federation and Egypt. [...]
NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) performed its final orbital maintenance maneuver (OMM-22) last Friday evening, April 11. This was the 22nd maneuver during the science mission, designed to keep the spacecraft at the desired altitudes for the three science instruments to obtain their best data.
After the primary mission concluded in March, we have been allowing the spacecraft to go much lower in altitude, in order to obtain the really high-value science data, acce [...]
On April 17, 1967, NASA's Surveyor 3 spacecraft launched from Cape Canaveral Air Force Station, Fla., on a mission to the lunar surface. A little more than two years after it landed on the moon with the goal of paving the way for a future human mission, the Surveyor 3 spacecraft got a visit from Apollo 12 Commander Charles Conrad Jr. and astronaut Alan L. Bean, who snapped this photo on November 20, 1969.
After Surveyor 1's initial studies of the lunar surface in 1966, Surveyor 3 made further [...]
In its sixth Martian winter, NASA's Mars Exploration Rover Opportunity now has cleaner solar arrays than in any Martian winter since its first on the Red Planet, in 2005. Cleaning effects of wind events in March boosted the amount of electricity available for the rover's work.
The mission is using the rover's added energy to inspect "Murray Ridge," on the western rim of Endeavour Crater, to learn about wet environments on ancient Mars.
During Opportunity's first decade on Mars and the [...]
The New Mexico Exoplanet Spectroscopic Survey Instrument (NESSI) will soon get its first "taste" of exoplanets, helping astronomers decipher their chemical composition. Exoplanets are planets that orbit stars beyond our sun.
NESSI got its first peek at the sky on April 3, 2014. It looked at Pollux, a star in the Gemini constellation, and Arcturus, in the Boötes constellation, confirming that all modes of the instrument are working.
"After five years of development, it's really excitin [...]
An image of a galaxy cluster taken by the NASA/ESA Hubble Space Telescope gives a remarkable cross-section of the Universe, showing objects at different distances and stages in cosmic history. They range from cosmic near neighbours to objects seen in the early years of the Universe. The 14-hour exposure shows objects around a billion times fainter than can be seen with the naked eye.
This new Hubble image showcases a remarkable variety of objects at different distances from us, extending back [...]
Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the origin of life may have been assisted by a supply of key molecules created in space and brought to Earth by comet and meteor impacts.
"It is always difficult to put a value on the connection between meteorites and the origin of life; for example, earlier work has shown that vitamin B3 could have [...]
Like a balloon bobbing along in the air while tied to a child's hand, a tracer has been found in the sun's atmosphere to help track the flow of material coursing underneath the sun's surface.
New research that uses data from NASA's Solar Dynamics Observatory, or SDO, to track bright points in the solar atmosphere and magnetic signatures on the sun's surface offers a way to probe the star's depths faster than ever before. The technique opens the door for near real-time mapping of the sun's roi [...]
