Cassini finds activities on the Saturn's moon, Dione

Dear followers,

The +NASA Cassini spacecraft which explores activities on Dione since 2004 has found some interesting data. The following picture, obtained from Cassini, shows the topography of a mountain known as Janiculum Dorsa on the Saturn's moon, Dione.

Scientists have found more evidence for the idea that Dione was likely active in the past. It could still be active now.

Actually, "A picture is emerging that suggests Dione could be a fossil of the wondrous activity Cassini discovered spraying from Saturn's geyser moon Enceladus or perhaps a weaker copycat Enceladus," said Bonnie Buratti of +NASA Jet Propulsion Laboratory in Pasadena, California, who manages the Cassini science team that studies icy satellites. The presence of a subsurface ocean on Dione would boost the astrobiological potential of this once-boring iceball.

Many other little moons in our solar system thought to have a subsurface ocean, such Saturn's moons Enceladus and Titan and Jupiter's moon Europa which are among the most geologically active worlds in our solar system.

Docking sensor still to be fixed on ISS before next ATV approach

Dear follower,

on June 5th, the European ATV should take off withe Ariane 5 to the International Space Station. However, the engineers are still working on a potential problem with a Laser Radar Reflector (LRR) which allows the spacecraft’s autonomous approach to the station. On April 26, Progress M-19M cargo docked at the ISS with one of its KURS (docking system) folded, due to a failure in the deployment mechanism.

The +European Space Agency, ESA didn't communicated about the possible issue or the solutions to fix the problem. However, Josh Byerly from +NASA  revealed that the Progress’ stowed antenna that may have caused the damage in the vicinity of the docking area, where are located the ATV’s navigation aids.

Engineers were not able to assess the potential damage on ISS because the area where the reflector is located is not visible from inside the station. Only external cameras of departing spacecraft could take a look to the critical area.  In the worst case scenario, ATV carries a backup docking system using telegoniometers that emit laser light at a different wavelength.

Although it is still to be confirmed, it is likely that the next crewed Soyuz set to launch on May 28 would be used to fly a replacement of the device.

We should get more news soon, so stay tune.

Same Water on Earth and Moon

Dear follower,

the water inside the Moon’s mantle came from primitive meteorites. The Moon is thought to have formed from a disc of debris left when a giant object hit the Earth 4.5 billion years ago, very early in Earth’s history. Scientists have long assumed that the heat from an impact of that size would cause hydrogen and other volatile elements to boil off into space, meaning the Moon must have started off completely dry as depicted on the following video .... or not finally ...

However, new research finds, the same source thought to have supplied most of the water on Earth. The findings raise new questions and lead to rethink the models about the forming of the Moon. 

Actually, +NASA  spacecraft and new research based on samples from the Apollo missions have revealed that the Moon has water both on its surface and below. In order to find the origin of the Moon’s water, scientists looked at melt inclusions found in samples brought back from the Apollo missions. Melt inclusions are tiny dots of volcanic glass trapped within crystals called olivine. The crystals prevent water escaping during an eruption and enable researchers to get an idea of what the inside of the Moon is like. 

The researches were performed by Erik Hauri of the Carnegie Institution of Washington, James Van Orman of Case Western Reserve University, and Malcolm Rutherford from Brown and have been published.

The researchers say, that there are some important processes we don’t yet understand about how planets and satellites are formed: “Our work suggests that even highly volatile elements may not be lost completely during a giant impact,” . “We need to go back to the drawing board and discover more about what giant impacts do, and we also need a better handle on volatile inventories in the Moon.”

ISS switches from Windows to Linux to improve reliability

Dear follower,

the United Space Alliance, which handles the computers boarded on the International Space Station in association with +NASA , has announced that the Windows XP computers aboard the ISS have been switched to +Linux . “We migrated key functions from Windows to Linux because we needed an operating system that was stable and reliable.”

Credit: 

This changing, it's not a surprise. +Linux  is the scientific community’s operating system of choice. The +CERN Large Hadron Collider is controlled by Linux. +NASA and +SpaceX ground stations use Linux. Actually, for critical applications that require absolute stability, which most scientific experiments are, Linux is the obvious choice. The fact that the entire OS is open source and can be easily customized for each experiment is obviously a very big draw, too.

Bright explosion ever observed on the Moon

Dear followers,

+NASA astronomers have been monitoring the Moon for signs of explosions due to meteorites hitting the lunar surface. This phenomenon is called "Lunar meteor showers"; and it have turned out to be more common than anyone expected. Actually hundreds of impacts are detected every year.

Credit: Nasa

"On March 17, 2013, an object about the size of a small boulder hit the lunar surface in Mare Imbrium," says Bill Cooke of NASA's Meteoroid Environment Office. "It exploded in a flash nearly 10 times as bright as anything we've ever seen before."

Dear follower, you should know that anyone looking at the Moon at the moment of impact could have seen the explosion; no telescope required.

Asteroid 1998 QE2 close to Earth on May 31th

Dead followers,

next Friday, on May 31th 2013, the asteroid 1998 QE2 will be close to Earth, closer than about 5.8 million kilometers, or about 15 times the distance between Earth and the Moon. The asteroid was discovered on August 19th 1998, by the Massachusetts Institute of Technology Lincoln Near Earth Asteroid Research (LINEAR) program near Socorro, New Mexico. 

The Asteroid 1998 QE2 will be an outstanding radar imaging target for the Goldstone and Arecibo telescope in order to obtain a series of high-resolution images that could reveal a wealth of surface features. The closest approach of the asteroid occurs on May 31 at 1:59 p.m. Pacific (4:59 p.m. Eastern / 20:59 UTC).

"Whenever an asteroid approaches this closely, it provides an important scientific opportunity to study it in detail to understand its size, shape, rotation, surface features, and what they can tell us about its origin. We will also use new radar measurements of the asteroid's distance and velocity to improve our calculation of its orbit and compute its motion farther into the future than we could otherwise." said Lance Benner , the principal investigator for the Goldstone radar observations from +NASA Jet Propulsion Laboratory  in Pasadena, Calif.

+NASA  places a high priority on tracking asteroids and protecting our home planet from them. In fact, the U.S. has the most robust and productive survey and detection program for discovering near-Earth objects. Last year, the NEO budget was increased from $6 million to $20 million.

In 2016, +NASA  will launch a robotic probe, called the OSIRIS-REx to the asteroid (101955) Bennu. Aside from monitoring potential threats, the study of asteroids and comets enables a valuable opportunity to learn more about the origins of our solar system, the source of water on Earth, and even the origin of organic molecules that lead to the development of life. 

+NASA  recently announced developing a first-ever mission to identify, capture and relocate an asteroid for human exploration. Using game-changing technologies advanced by the Administration, this mission would mark an unprecedented technological achievement that raises the bar of what humans can do in space. Capturing and redirecting an asteroid will integrate the best of NASA's science, technology and human exploration capabilities and draw on the innovation of America's brightest scientists and engineers.

Kepler Space Telescope is down

Dear followers,

bad news for the search for exo-planets. The U.S. space telescope Kepler which has increased the discovery of new planets since 2009, is paralyzed by a technical problem. This dysfunction could spell the premature end of his four-year mission, +NASA said yesterday (May 15th 2013).

Kepler 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.

+Kepler Space Telescope is blocked by the malfunction of a mechanism which allows the telescope to focus on a given point in the sky towards said John Grunsfeld, the head of the science division of the U.S. space agency. "The telescope was put into safe mode" to ensure that the solar panels facing the sun to recharge the batteries and continue to communicate with Earth, he said.

Engineers found last week that it did not move despite gyroscope controls from the ground. This problem had already occurred in July with another gyro Kepler has stopped working, said the head of NASA.

"Unfortunately Kepler is not a place where you can send astronauts" to fix it, he said, explaining that the engineers' carefully examined the data (...) to see if it is possible to resume the scientific activities of the telescope. " But "we are not yet ready to declare the end of Kepler," insisted John Grunsfeld, arguing that "in all respects the Kepler mission was a success."

In 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.

ESA's Vega launcher performes new success with commercials satellite and micro-satellite

Dear follower,

after the successful launch of +NASA few days ago, +European Space Agency, ESA scores a second flight with the newest launch vehicle, Vega from Europe’s Spaceport in Kourou, French Guiana.

Two Earth observation satellites, ESA’s Proba-V and Vietnam’s VNREDSat‑1A, were released into different orbits, demonstrating the rocket’s versatility. Estonia’s first satellite, the ESTCube‑1 technology demonstrator, was also released into orbit.

After releasing the first satellite Proba-V, the upper stage performed a third burn and the top half of the egg-shaped Vega Secondary Payload Adapter was ejected. After a fourth burn to circularize the orbit at an altitude of 704 km, VNREDSat-1A was released around 2 hours into flight. ESTCube‑1 was ejected from its dispenser few minutes later.

ESTCube-1 is Estonia’s first satellite. This 1.3 kg CubeSat was designed and built by students from the University of Tartu with a contribution from the Finnish Meteorological Institute. It will deploy a 10 m-long tether to demonstrate electrostatic movement through the plasma flow, which could lead to electrostatic solar sails for propellant-less interplanetary travel.
