Orb-1 mission of the Antares rocket delayed due to high space radiation environment
Dear followers,
yesterday, we announced that the Antares is already on the launch Pad-0A at +NASA's Wallops Flight Facility. This morning, the Antares launch team decided to delay the space launch due to an unusually high level of space radiation that exceeded by a considerable margin the constraints imposed on the mission to ensure the rocket's electronic systems are not impacted by a harsh radiation environment.

The space rocket is in advance of a planned launch on January 8th at 1:32 p.m. EST on the Wallops Island, VA. The Orbital-1 mission is Orbital Sciences' first contracted cargo delivery flight to the space station for NASA. Among the cargo aboard Cygnus set to launch to the international space station are science experiments, crew provisions, and other hardware.
Stay tuned
[Update] : if the level of radiations moves down, Orbital Sciences announces that the launch could be performed on Thursday, the launch targeted launch time would be 1:10 p.m. (EST), with Cygnus arriving at the ISS Sunday morning, January 12.

The image was obtained using the wide-field view of the Mosaic camera on the Mayall 4 meters telescope at Kitt Peak National Observatory. The picture shows the nebula known as the "Ear Nebula". This nebula is relatively old. It was discovered in 2005 by the IPHAS of the Northern Galactic Plane. The picture is built with observations in the Hydrogen alpha (red) and Oxygen (blue) filters. The North is to the top of the image, while the East is to the left.

ISS without half of its vital cooling system
Dear followers,
yesterday, on Wednesday December 11th, the International Space Station lost half of its vital cooling system, due to a partial power down of some systems.
The safety of the members crew is under control, "at no time was the crew or the station itself in any danger" announced officially +NASA . All the astronauts slept on the orbiting laboratory as scheduled.
Credits: NASA
The trouble on the international space station occurred when one of two pumps used to circulate ammonia coolant outside of the space station shut itself down after the detection of unexpected low temperatures. The shutdown cut off half of the ability of the space system to regulate temperatures for both its internal and external systems.
The engineer on the ground are working hard to troubleshoot the issue. If the showdown of the cooling system is due to a hardware problem, it may require that astronauts go outside ISS to replace or fix the pump module with a spare unit.
More news soon, so stay tuned.

NASA discovers an ancient lake on Mars
Dear followers,
after many months on Mars, the Curiosity rover reveals its major discovery which could change the space field research. Actually, the space rover has revealed the evidence of an ancient lake with water that could plausibly be described as drinkable. This validates the first analyses performed and published few months ago: the first scoop of soil analysed by the analytic suite in the belly of martian rover reveals that fine materials on the surface of the planet contain several percent water by weight.

This discovery might emphasize the probability of an ancient life on the red planet; “If we put microbes from Earth and put them in this lake on Mars, would they survive? Would they survive and thrive? And the answer is yes,” said John Grotzinger, a Caltech planetary geologist who is the chief scientist of the Curiosity rover mission.
As described in the science paper, "A Habitable Fluvio-Lacustrine Environment at Yellowknife Bay, Gale Crater, Mars", the aqueous environment found on the red planet was characterized by neutral pH, low salinity, and variable redox states of both iron and sulfur species. C, H, O, S, N, and P were measured directly as key biogenic elements, and by inference P is assumed to have been available. These results highlight the biological viability of fluvial-lacustrine environments in the post-Noachian history of Mars.

The Chinese spacecraft is in Lunar orbit
Dear followers,
few days ago, China sent its third spacecraft for a Lunar mission with the support of the European Space Agency for the communication with the spacecraft.
Last Friday, so, less than five days after leaving Earth, the China's Chang'e 3 spacecraft reached lunar orbit to prepare for an historic landing on the Moon. The landing should take place in the moon's Bay of Rainbows, a dark lava plain on the upper-left quadrant of the moon's near side, around December 14th 2013.

The spacecraft is now flying in orbit 100 km above the Moon. This week it plans to move down and lost its altitude. The spacecraft, Chang'e 3, will use its main engine to make a soft landing in the Moon ground. In order to guide its landing, the spacecraft will use some terrain recognition sensors. Around 1 meter above the moon, the lander will autonomously cut off its engine and drop to the lunar surface.
Stay tuned for the live landing in the next days.

ESA collaborates with China for its mission to the Moon
Dear followers,
as you know, few days ago, the China National Space Administration sent its first rover, called Yutu, to the Moon. For this mission, China is helped by the +European Space Agency, ESA . Actually, after the liftoff of the China’s Chang’e 3 spacecraft, the ESA's network of tracking stations is providing a crucial support during all the Lunar cruise of the spacecraft. This mission is the third Chinese mission to the moon after the Chang'e 1 and Chang'e 2 lunar orbiter flights, launched in 2007 and 2010, respectively.

After its liftoff from the Xichang Satellite Launch Center in the country's Sichuan province, the ESA’s station in Kourou, French Guiana, started receiving signals from the spacecraft and uploading commands on behalf of the Chinese control center. This tracking is operated during the voyage to the Earth's moon. Next, during the descent and after the landing some other ESA's space stations will follow the rover Yutu mission.

The landing of Yutu is planned to be in the Sea of Rainbows on December 14th 2013. This landing will be the first since Russia’s Luna-24 in 1976. This mission is the second step of the China's lunar exploration program. That program consists of three major steps: Orbit, land and finally return some Moon rock samples to Earth by 2020.

Curiosity Mars rover is back after a power glitch
Dear followers,
The NASA's space rover Curiosity which explores the Mars's land for 16 months has stopped the whole of the science operations and driving during six days. Actually, an electrical power system glitch had induced a system dysfunction on the space rover. Fortunately, the problem has now been resolved.
This dysfunction is the second trouble observed on the martian rover after an other one which has been observed and which has been assigned to radiation effects. For the moment the cause of this dysfunction has still not been found but the +NASA Jet Propulsion Laboratory engineers are working on it. “We made a list of potential causes, and then determined which we could cross off the list, one by one,” said rover electrical engineer Rob Zimmerman of NASA’s Jet Propulsion Laboratory, in Pasadena, California.

For the moment, Curiosity has already accomplished its primary science goal of discovering a habitable zone at her landing site. This kind of dysfunction could be critical for the Curiosity mission, but the martian rover is safe now.
In the next months, the Curiosity rover will be join by the Maven spacecraft sent by NASA two weeks ago.
Stay tuned for the next news about the red planet discoveries.

A 'second light' mission for the Kepler space telescope
Dear followers,
Few months ago, in May, the research working on the search of exo-planets received a very bad news from the US space telescope Kepler. Actually, the +Kepler Space Telescope was down due to a malfunction of a mechanism which allows the telescope to focus on a given point in the sky towards.
However, now, Engineers from the Kepler mission and Ball Aerospace have developed a way of keeping the stability of the spacecraft. The solution is based on the pressure provide by the Sun on the surface of spacecraft.
based on this solution the second life of Kepler will be start. The US space telescope which has increased the discovery of new planets since 2009 is the first telescope dedicated to the search for planets sisters of the Earth in other solar systems in our galaxy, the Milky Way. So far it has detected 2,740 potential exo-planets which 122 were confirmed to the day using telescopes and other equipment.

In last April, astronauts had announced the discovery by Kepler, two exoplanets with the greatest similarity to Earth ever recorded and where water could remain liquid and potentially allow life to exist.

The ISON comet was not fully destroyed by the Sun
Dear followers,
last night the ISON comet followed during last weeks, passed really close to the Sun and was mainly destroyed. Actually, the SOHO images (from 00:18 UTC on Novemer 29th), presented at the end of the video below, sure looks like something survived after its passage close to the SUN.
