What can you see in July’s night skies? Mars opposition on the 27th, when Mars, Earth and the Sun all line up, and Mars’ closest approach to Earth since 2003 on the 31st. That means great Mars viewing, though the planet-wide Martian dust storm will make seeing details more difficult.

The TSB determined that the bracket securing the right front lift strut to the fuselage failed while in flight as the result of metal fatigue. The failure caused the right wing to separate from the aircraft. According to the report, the bracket had accumulated 402.2 hours when the failure occurred. The fatigue crack began at the bolt hole, and a "significant number" of secondary and parallel cracks were found underneath the surface of the bracket. NASA has chosen Jezero Crater as the landing site for its upcoming Mars 2020 rover mission after a five year search, during which every available detail of more than 60 candidate locations on the Red Planet was scrutinized and debated by the mission team and the planetary science community. The rover mission is scheduled to launch in July 2020 as NASA’s next step in exploration of the Red Planet. It will not only seek signs of ancient habitable conditions – and past microbial life -- but the rover also will collect rock and soil samples and store them in a cache on the planet's surface. NASA and the European Space Agency are studying future mission concepts to retrieve the samples and return them to Earth, so this landing site sets the stage for the next decade of Mars exploration. The first ACJ320neo successfully completed a two hour and 40 minute first flight from Hamburg on November 16th, getting its short test-program off to a good start. The first ACJ320neo made a successful first flight from Hamburg on 16th November 2018. Derived from the popular A320neo airliner family, some 500 of which are in airline service, the corporate jet version includes features such as extra fuel-tanks in the cargo-hold that will deliver even more intercontinental range, plus greater cabin-pressure for better passenger comfort.

The Popocatepetl volcano outside Mexico City has spewed ash and smoke, prompting the country's civil protection agency to issue a warning on Monday. The National Disaster Prevention Center has warned residents to stay away from the volcano, since ballistic fragments can fall. Local population has been asked to stay away from the bottoms of ravines due to potential landslides and mudflows in case of heavy rains.

NASA scientists have tracked gravity waves spreading upward for hundreds of miles and outward for thousands of miles in concentric rings, like ripples in a pond. The waves were created by a large convective storm in 2013 that also spawned a deadly tornado. The visualization shows near-simultaneous measurements of the gravity waves in the troposphere, stratosphere and ionosphere. The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite detected gravity waves in the troposphere and stratosphere 12 hours before a deadly EF5 tornado in Moore, Oklahoma. Even stronger waves were detected 11 hours later during AIRS’ next pass. The tornado and waves were produced by a long-lived storm system. In the ionosphere 250 miles (400 kilometers) above Earth's surface, the gravity waves appear as traveling ionospheric disturbances (TIDs) -- disturbances in the electron content of the region. These were observed in Total Electron Content measurements by ground-based GPS receivers throughout the south central United States. In the visualization, these ionospheric disturbances are shown in greens and yellows. Gravity waves are formed when a disturbance causes air to be displaced into a region of different air density. There are many common causes for this besides storms -- for example, an air current strikes a mountain and is pushed upward. As gravity waves grow and propagate upward, they play important roles in the upper levels of the atmosphere. In the stratosphere, gravity waves help drive the atmospheric circulation and move ozone from the tropics to the poles. Observations such as these at multiple heights in the atmosphere provide a unique perspective on how atmospheric layers are linked together. Understanding the spread of gravity waves improves global weather forecasting and space weather forecasting. NASA scientists have tracked gravity waves traveling thousands of miles across our atmosphere in concentric rings. Large storms can create these waves, which grow and spread upward hundreds of miles above Earth's surface. The AIRS instrument on NASA's Aqua satellite detected gravity waves in the troposphere and stratosphere 12 hours before a deadly EF5 tornado in Moore, Oklahoma, in 2014. On the instrument's next pass 11 hours later, it detected even stronger waves. We pull up 250 miles to the ionosphere, where the waves can be observed by GPS satellites. Here gravity waves are shown in greens and yellows, like ripples in a pond. The waves and tornado were both produced by a long-lived storm system.

NASA issues warning about space herpes NASA has issued a warning about space herpes after a study found the virus was reactivating in crew aboard Space Shuttle and International Space Station missions. According to the agency, while only a small proportion of the astronauts develop symptoms as a result of the dormant virus awakening, it could spell danger for longer spaceflight missions - for instance to Mars. "NASA astronauts endure weeks or even months exposed to microgravity and cosmic radiation - not to mention the extreme G forces of take-off and re-entry," said Dr Satish Mehta. "This physical challenge is compounded by more familiar stressors like social separation, confinement and an altered sleep-wake cycle," added Dr Mehta, senior author of the paper and academic at the Johnson Space Centre. The research is published in the journal Frontiers in Microbiology and concerns the reactivation of the virus, rather than a new virus which had developed in space. NASA's thorough medical systems measure the physiological impact of spaceflight by analysing astronauts' saliva, blood, and urine throughout spaceflight. "During spaceflight there is a rise in secretion of stress hormones like cortisol and adrenaline, which are known to suppress the immune system," the study found. "In keeping with this, we find that astronaut's immune cells - particularly those that normally suppress and eliminate viruses - become less effective during spaceflight and sometimes for up to 60 days after. "Due to this suppression of the immune system, the astronauts' bodies are less able to keep dormant viruses down, allowing them to reactivate. "To date, 47 out of 89 53% astronauts on short space shuttle flights, and 14 out of 23 61% on longer ISS missions shed herpes viruses in their saliva or urine samples," reported Dr Mehta. "These frequencies - as well as the quantity - of viral shedding are markedly higher than in samples from before or after flight, or from matched healthy controls. ""Only six astronauts developed any symptoms due to viral reactivation," said Dr Mehta. "All were minor. "There are eight known herpes virus, including the strain for chickenpox, which once contracted will stay within their hosts' nerve cells for their entire life. They are mostly kept suppressed by the immune system, but if the immune system itself is suppressed by space exploration, then they could pose a significant risks to astronauts travelling to Mars or beyond. The research found that the longer the spaceflight mission, the more it seemed the viruses were reactivating.

The transport ministry is pushing to close a loop-hole which requires only insurance documentation to clear motor vehicles at the ports. Transport officials suggest over the years, the current policy has allowed thousands of unregistered vehicles to illegally operate on St. Lucia’s roadways. The traffic department in the police force says the issue poses a threat to national security.

Olivia Billett, the OSIRIS-REx spacecraft science lead at Lockheed Martin, talks about the complexities of orbiting around asteroid Bennu. The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft launched Sept. 8, 2016, and began orbiting asteroid Bennu on Dec. 31, 2018. Its primary science objective is to study Bennu and collect a sample for return to Earth in 2023. Bennu is a carbon-rich asteroid that records the earliest history of our solar system, and which may contain the raw ingredients of life.
