MASCOT the asteroid lander is ready for its launch on November 30th

Dear readers and followers,

While Philae sleeps on the comet 67P, the spacecraft MASCOT (Mobile Asteroid Surface Scout) is ready for its launch on 30 November 2014. MASCOT is an asteroid lander developed by +DLR, German Aerospace Center, the Japan space agency +JAXA | 宇宙航空研究開発機構 and the French space agency, +CNES. 

In 2018 the Japanese Hayabusa 2 Mission will feature an asteroid landing and will, for the first time, allow for data acquisition at various points of this kind of celestial body, assisted by MASCOT , the hopping landing craft developed by the German Aerospace Center.

The plan is to send the orbiter to its destination in 2014. Upon arrival in 2018, the spacecraft will initially remain in orbit to scout the unknown terrain. A stable, yet extremely light cover will protect the shoe box-sized lander as it falls to the asteroid’s surface. The four instruments designed to conduct in situ measurements on the asteroid are located inside the DLR landing craft:

• the infrared spectrometer that will analyse the surface composition
• magnetometer to investigate the magnetic field
• a wide-angle camera to record the landing site and the fine structure of the soil
• a radiometer that will measure surface temperatures, among other things.

Once the initial measurements are complete, MASCOT will hop to the next measurement site, providing scientists with data from different positions on asteroid on 1999 JU 3, gathered over two asteroid days and nights. During its mission, the landing craft will be monitored from the DLR Microgravity User Support Center (MUSC).

Airbus will develop and built service module of NASA's Orion human space capsule

Dear readers and followers,

The contract for Airbus of about 390 million euros is for the development and construction of the service module for Orion, the future American human space capsule. The service module will provide propulsion, power supply, thermal control and the central elements of the life support system of the American capsule.

Credit image: +NASA 

It is the first time that Europe has been involved in providing system-critical elements for an American space project. In December 2012, US space agency +NASA  and +European Space Agency, ESA had agreed to certify the new US Orion spacecraft in conjunction with the European service module.

This module is based on the design of and the experience gained from the Automated Transfer Vehicle developed and constructed by Airbus Defence and Space on behalf of ESA as a supply craft for the International Space Station.

Francois Auque, Head of Space Systems, told BOB fm: "This follow-on contract is a mark of confidence in our expertise as well as in our ability to deliver reliable state-of-the-art space systems on time and within budget. Thanks to this programme and the continuous investments we make, we are able to maintain our technological lead.

Credit image: +European Space Agency, ESA 

In the wake of the ATV's outstanding five flawless missions to the ISS, this programme is yet another example of the important role that Europe plays globally in the field of human space flight".

The intention is to use the Orion space capsule for human missions to the Moon, to asteroids and into the depths of space. It comes after the success of Stevenage-built spaceship Rosetta, that was able to carry probe Philae close enough to land it on a comet last week. With him was the UK's first astronaut, Tim Peake - who told BOB fm at the Exo-Mars test yard that he was fascinated by flying when working as a test-pilot. 

He added: "It's great to see the Mars Yard at Stevenage Airbus has expanded. It's amazing to see the Mars programme progressing towards its launch in 2016".

Philae discovers organic molecules on the comet 67P/Churyumov-Gerasimenko

Dear readers and followers,

An instrument aboard the Philae lander detected the molecules after “sniffing” the comet’s atmosphere. An organic compound is one whose molecules contain the carbon atom, the basis of life on earth. Scientists are analysing the data to see whether the organic compounds detected by Philae are simple ones, such as methane and methanol, or a more complex species such as amino acids, the building blocks for proteins.

Credit images: ESA/Rosetta/Philae/

A drill on Philae also obtained some material from the comet’s hard surface, but data about organic molecules from that experiment have yet to be fully analysed. Comets contain some of the most pristine materials in the solar system, dating to about 4.5 billion years ago. Previous studies have suggested that comets forge organic material in their dusty atmospheres.

A study of the comet’s organic materials “will help us to understand whether organic molecules were brought by comets to the early earth,” which could have kickstarted life here, said Stephan Ulamec, the Philae lander manager and scientist at the German Aerospace Centre. The agency runs the lander control centre and oversaw the comet landing last Thursday.

Researchers had expected to find organic molecules on the comet, known as 67P/Churyumov-Gerasimenko. But thanks to the probe, they are for the first time able to conduct a direct search for organic molecules in both the comet’s gases and its surface material.

The data sent back by Philae, part of a European Space Agency mission. now will be checked against similar information already obtained by the orbiting Rosetta. In early August, when Rosetta was within 200km of the comet, one of its sensors was able to study the coma, or envelope of gases surrounding the comet’s nucleus. Those early measurements detected water, carbon monoxide and carbon dioxide, which were likely to have been released from below the comet’s surface layer. It also found traces of ammonia, methane and methanol. In October, Rosetta scientists studying the coma said they had picked up traces of the organic compound formaldehyde as well as other molecules, including sulfur dioxide and hydrogen sulfide, which smells like rotten eggs.

An even bigger find would be the discovery of an amino acid on comet 67P. In 2009, a US spacecraft discovered the amino acid glycine on a comet. A similar find on 67P would bolster a view that life on earth was seeded by comets that brought organic compounds with them.

Although Philae’s primary battery ran out of power on Saturday (AEDT), scientists completed a manoeuvre that has positioned one of the probe’s larger solar panels more fully toward sunlight. It means that the probe may yet come to life next year or a bit earlier, as the comet heads closer to the sun.

“We are very confident that in coming months we’ll get more sun and power and Philae can be reactivated,” Dr Ulamec said.

Leonids Meteor shower peak occurs tomorrow Morning

Dear readers and followers,

This year’s Leonids meteor shower peaks tomorrow on the morning of November 18th. If forecasters are correct, the shower should produce a mild but pretty sprinkling of meteors. The waning crescent moon will not substantially interfere with viewing the Leonid shower.

“We’re predicting 10 to 15 meteors per hour,” says Bill Cooke of the Meteoroid Environment Office at NASA’s Marshall Space Flight Center. “For best viewing, wait until after midnight on November 18th, with the peak of the shower occurring just before sunrise.”

Credit video: +NASA 

Cooke also recommends going to a location away from city lights, dressing warmly, and lie flat on your back and look straight up. No special viewing equipment needed — just your eyes.

Leonids are bits of debris from Comet Tempel-Tuttle. Every 33 years the comet visits the inner solar system and leaves a stream of dusty debris in its wake. Many of these streams have drifted across the November portion of Earth’s orbit. Whenever our planet hits one, meteors appear to be flying out of the constellation Leo.

A live viewing opportunity is available via Ustream from a telescope at Marshall Space Flight Center. The Ustream feed will be live beginning Monday, November 17th at 6:30 p.m. CST here and will continue until sunrise on Tuesday November 18th.

Press conference of The French Space Agency about the safety and the location of Philae after its landing

Dear readers and followers,

after the successful touch-down of the lander Philae on the comet 67P Churyumov Gerasimenko yesterday! The french space agency is doing a conference from Toulouse, France, to clarify all the technical points and the safety of the Philae spacecraft since the landing! Sorry for English people, the video is in french.

Credit image: +CNES 

Touchdown was planned to take place at a speed of around 1 m/s after its separation from Rosseta, with the three-legged landing gear absorbing the impact to prevent rebound, and an ice screw in each foot driving into the surface.

But during the final health checks of the lander before separation, a problem was detected with the small thruster on top that was designed to counteract the recoil of the harpoons to push the lander down onto the surface. The conditions of landing, including whether or not the thruster performed, along with the exact location of Philae on the comet are being analysed.

The lander seems be close to a kind of cave which stop its moves after two bound since its this touch-down. 8/10 scientific instruments are working normally for the moment. The two other stay off for the moment because they need to move and drill the comet. For safety of the lander, engineer are still working and analyzing data to determine if they will activate the 2 last instruments.

Worms of school projects onboard Antares rocket have been also lost

Dear readers and followers,

few days after the terrific failure during take-off of the Antares space rocket, the space community starts to see the consequences for the all projects linked to this dramatic event. The rocket was carrying more than 2200 kg of equipment and supplies for the international space station. No one was injured when the rocket, built and launched by +Orbital Sciences and Technologies, Inc., exploded into what witnesses said looked like a "ball of fire" after lifting off from the NASA Wallops Flight Facility on Wallops Island, Virginia.

Actually, over a dozen school projects were onboard the U.S. supply rocket that exploded shortly after liftoff from the Virginia regional space launch pad. Fortunately, a group of California students will have another shot at getting their project.

The project, developed by students at the Urban Promise Academy middle school in Oakland, would have sent the worms to the International Space Station to study the effects of space on composting."They were very distressed initially when the rocket blew up. Of all the points of potential failure, that wasn't one that students or staff had anticipated," said Flint, a staff member of the school leading this student project. But Flint added that school officials were assured they would have a second chance to send the project into space on an upcoming launch, though it was not immediately clear when.

The study of life in space is a huge topic and many experiment are done in orbit, such as the last one of the Russian space program with gecko. 

The project was among 18 student investigations onboard the rocket when it exploded, according to a NASA statement. The winners were selected from a pool of nearly 1500 proposals from across the country, +NASA  said.

It was not immediately clear whether the other projects would also be included on another flight.

Fireball meteor in western Japan sky

Dear readers and followers,

Yesterday evening, on Monday November 3nd, people in western Japan have reported sightings of a sparkling light racing across the sky, as illustrated in the following picture. Experts say it was probably a "fireball" meteor, a piece of an asteroid that ignites upon entering Earth's atmosphere, and any surviving fragments mostly likely ended up in the sea. A remote controlled camera at Fukuoka airport recorded an object emitting a strong green light, while another camera at Hakata port showed a faint orange light.

Incident Response Team completed an initial assessment of Wallops Island

Dear readers and follower,

The Wallops Incident Response Team completed today an initial assessment of Wallops Island, Virginia, following the catastrophic failure of Orbital Science Corp.’s Antares rocket shortly after liftoff at 6:22 p.m. (local time, EDT) Tuesday, October 28th , from Pad 0A of the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia.

“I want to praise the launch team, range safety, all of our emergency responders and those who provided mutual aid and support on a highly-professional response that ensured the safety of our most important resource, our people,” announced Bill Wrobel, Wallops director. “In the coming days and weeks ahead, we'll continue to assess the damage on the island and begin the process of moving forward to restore our space launch capabilities. There's no doubt in my mind that we will rebound stronger than ever.”

The initial assessment is a cursory look; it will take many more weeks to further understand and analyze the full extent of the effects of the event. A number of support buildings in the immediate area have broken windows and imploded doors. A sounding rocket launcher adjacent to the pad, and buildings nearest the pad, suffered the most severe damage. At Pad 0A the initial assessment showed damage to the transporter erector launcher and lightning suppression rods, as well as debris around the pad.

The Wallops environmental team also is conducting assessments at the site. Preliminary observations are that the environmental effects of the launch failure were largely contained within the southern third of Wallops Island, in the area immediately adjacent to the pad. Immediately after the incident, the Wallops’ industrial hygienist collected air samples at the Wallops mainland area, the Highway 175 causeway, and on Chincoteague Island. No hazardous substances were detected at the sampled locations. Additional air, soil and water samples will be collected from the incident area as well as at control sites for comparative analysis.

The Coast Guard and Virginia Marine Resources Commission reported today they have not observed any obvious signs of water pollution, such as oil sheens. Furthermore, initial assessments have not revealed any obvious impacts to fish or wildlife resources. The Incident Response Team continues to monitor and assess.

Based on initial sweeps conducted by an Orbital safety team, it appears a significant amount of debris remains on the site and it is likely substantial hardware evidence will be available to aid in determining root cause of the Antares launch failure. Some of the Cygnus cargo has also been found and will be retrieved as soon as they have clearance to do so to see if any survived intact. 

After up close visual inspections by the safety team, it still appears the launch site itself avoided major damage. There is some evidence of damage to piping that runs between the fuel and commodity storage vessels and the launch mount, but no evidence of significant damage to either the storage vessels or launch mount. Detailed evaluations by MARS and their engineering team will occur in the next couple of days. An Orbital-led team has begun cataloging and documenting the location of all pieces of debris over the next several days after which the debris will be relocated to storage bays on the island for further evaluation.

Telemetry data has been released to Orbital and their engineers presented a very quick look assessment to the Accident Investigation Board at the end of the day. It appears the Antares vehicle had a nominal pre-launch and launch sequence with no issues noted. All systems appeared to be performing nominally until approximately T+15 seconds at which point the failure occurred. 

Evidence suggests the failure initiated in the first stage after which the vehicle lost its propulsive capability and fell back to the ground impacting near, but not on, the launch pad. Prior to impacting the ground, the rocket’s Flight Termination System was engaged by the designated official in the Wallops Range Control Center.

Comet 67P/ Tchourioumov-Guérassimenko smells terrible

Dear readers and followers,

the European spacecraft, Rosetta is orbiting the distant comet 67P Churyumov Gerasimenko and revealed funny conclusions. It seems that the comet smells terrible. Since early August, the Rosetta Orbiter Sensor for Ion and Neutral Analysis (ROSINA) has been ‘sniffing the fumes’ of 67P/C-G with its two mass spectrometers.

Actually, "It stinks" said Kathrin Altwegg, a researcher at the University of Bern in Switzerland who runs an instrument called ROSINA that picked up the odor.

Credit image : +European Space Agency, ESA 

The European space agency has realeased the constitution of the analyse: The mix includes ammonia (NH3), hydrogen sulphide (H2S), formaldehyde (CH2O) and methanol (CH3OH). As the Kathrin Altwegg, principal investigator for ROSINA, put it: “The perfume of 67P/C-G is quite strong, with the odour of rotten eggs (hydrogen sulphide), horse stable (ammonia), and the pungent, suffocating odour of formaldehyde. This is mixed with the faint, bitter, almond-like aroma of hydrogen cyanide. Add some whiff of alcohol (methanol) to this mixture, paired with the vinegar-like aroma of sulphur dioxide and a hint of the sweet aromatic scent of carbon disulphide, and you arrive at the ‘perfume’ of our comet.”

Credit image: +European Space Agency, ESA 

Fun for now. But that could change. The comet is currently getting closer and closer to the sun. And like anything you leave out in the sun too long, it will soon start to smell even worse.

After a 10 year journey of some seven billion kilometres, the Rosetta mission is now heading towards its next major milestone : setting the lander Philae on a comet. Rosetta is a robotic space probe built and launched by the +European Space Agency, ESA to perform a detailed study of comet called 67P/Churyumov–Gerasimenko with both an orbiter and lander module (Philae).

NASA stops the rumors about 3 days without sun on Earth

Dear readers and followers,

after many rumors and hearsays on the web and social networks since the last week,  +NASA confirms that NONE full day of darkness will occur this year in the days in December 21st, 22nd and 23rd. The land will NOT remain during these three days without sun. The rumor talked about a huge solar storm, but it will not be the case. There are many solar storm each months. In February 2014 a powerful X4.9-class solar flare has been recorded by NASA . This solar flare is the most intense flare of 2014 so far, and one of the most intense of the current solar cycle. Solar flare are really critical, specially for the spacecrafts orbiting Earth. Few weeks ago, the Orb-1 mission of the Antares rocket delayed due to high space radiation environment induced by a high class solar flare. Fortunately, the solar flare was not Earth directed.

The head director of +NASA Charles Bolden did a announcement witht he aim to stop the rumors and ask people to stay calm. 

The rumor is used to come back on the web each year. This hearsay talked about a plunge into total darkness for three days on Earth;this is the incredible event announced for centuries by different traditions and religions and supposed support the transformation of the Earth in our time..... only rumors !!

So you could stay calm and enjoy the end of 2014 with your friends and family in peace.

Counting down before the landing of Rosetta mission on the comet

Dear readers and followers,

After a 10 year journey of some seven billion kilometres, the Rosetta mission is now heading towards its next major milestone : setting the lander Philae on a comet. Rosetta is a robotic space probe built and launched by the +European Space Agency, ESA to perform a detailed study of comet called 67P/Churyumov–Gerasimenko with both an orbiter and lander module (Philae).

On November 12th 2014, a lander is scheduled to touch down on a comet for the first time in the history of spaceflight. “We don’t know exactly what awaits us there,” says lander Project Manager Stephan Ulamec from the +DLR, German Aerospace Center .

Philae’s landing site, currently known as Site J, is located on the smaller of the comet’s two ‘lobes’, with a backup site on the larger lobe. The sites were selected just six weeks after Rosetta arrived at the comet on August 6th, following its 10-year journey through the Solar System. Site J was chosen unanimously over four other candidate sites as the primary landing site because the majority of terrain within a square kilometre area has slopes of less than 30º relative to the local vertical and because there are relatively few large boulders.

Credit image: +European Space Agency, ESA 

Landing on Comet 67P/Churyumov-Gerasimenko will enable scientists to carry out experiments in situ for the first time. Comets are considered to be witnesses to the birth of the Solar System. Will the surface of the comet be in a primordial state? Do comets show evidence of prebiotic molecules and water, and did they therefore play a role in the origin of life on Earth? The Rosetta mission is expected to help answer such questions.
