Massive Narrowbody Aircraft Orders Rattle Dubai
After failing to clinch a much-anticipated A380 order from Emirates Airlines and watching Boeing secure additional orders for its 777 and 787s, Airbus unveiled an order for 430 A320 jets from low-cost airline investor Bill Franke’s Indigo Partners worth $49.5 billion based on list prices. This makes it one of the largest single orders in history, at least in terms of aircraft numbers.

Experimental X-56A's thin, bendy wings herald a revolution in airliner design
According to NASA, the future of long-range aircraft lies in very long, thin, flexible wings, with a very high aspect ratio, to give same lift than legacy wings, but with less weight and drag. Main problem with this kind of wings is flutter, that destroys them.
Working with Lockheed Martin's Skunk Works, NASA has been building and testing UAVs that use active flutter control measures to detect when the vibrations are beginning, and intervene to smooth out them, so that passengers can enjoy their ride while their aircraft is also not tearing itself apart and falling to a fiery doom.

NASA's Mars 2020 Mission Performs First Supersonic Parachute Test
Landing on Mars is difficult and not always successful. Well-designed advance testing helps. An ambitious NASA Mars rover mission set to launch in 2020 will rely on a special parachute to slow the spacecraft down as it enters the Martian atmosphere at over 12,000 mph (5.4 kilometers per second). Preparations for this mission have provided, for the first time, dramatic video of the parachute opening at supersonic speed.

Dubai wants a guarantee that Airbus will keep production of the A380 before placing a new order
Dubai wants a guarantee that Airbus (AIR.PA) will keep production of the A380 superjumbo open for at least 10 years before state-owned Emirates places a new order
Airbus Helicopters completes first firing campaign with HForce-equipped H145M
Donauwörth – Airbus Helicopters has recently completed a ballistic development test of an HForce weapon system on a H145M on Pápa Airbase in Hungary. The tested system included guns (FN Herstal HMP400), unguided rockets (Thales FZ231) and cannons (Nexter NC621) as well as an electro-optical targeting system by Wescam (MX15) and a helmet mounted sight display by Thales (Scorpion). All planned and required tests were performed in a tight and demanding time schedule.
“This is an important milestone towards the qualification of HForce on the H145M, which is planned for end 2018”, said Axel Humpert, Head of H145 Programme. “The positive results of this first ballistic development test are the outcome of a very good and professional cooperation between all parties involved, especially with the Hungarian Ministry of Defence.”
Next steps prior to the qualification of HForce on the H145M are the development testing of laser-guided rockets in Sweden before the end of the year as well as additional live-firing trials in summer 2018.
HForce is an innovative, incremental and integrated high performance weapon system that can easily be fitted (“plug and play”) into Airbus Helicopter’s military platforms such as H125M, H145M and H225M for ambitious and smart military operations where flexibility of mission equipment is a vital criterion. It is designed to meet the requirements of defence agencies seeking light attack mission capabilities or a complement to their existing fleet of specialized attack helicopters. Meanwhile, qualification of the core HForce system is on track for end 2017, following an extensive flight-test campaign carried out on a H225M testbed.
The H145M is a proven military helicopter, derived from the H145, a rugged workhorse and best in its class for rough EMS and police missions. First delivery of the H145 took place in 2014. The entire H145 fleet has now clocked up more than 80,000 flight hours. With a maximum take-off weight of 3.7 tonnes the H145M is an agile light attack helicopter. It perfectly matches the needs of Special Forces, can be used for a wide range of tasks, including armed reconnaissance, ground fire support, anti-tank warfare, escort, tactical transport, MEDEVAC and CASEVAC. Customers for the H145M include Germany – which in June received their 15th and final H145M LUH SOF helicopter on time and on budget – as well as the Republic of Serbia and the Kingdom of Thailand.
Airbus receives go-ahead for twin GRACE-FO satellites
press release
NASA-JPL and GFZ will continue a series of vital Earth system measurements
with new satellites in spring 2018
Transport to Vandenberg launch site in California planned for December
Friedrichshafen / Ottobrunn, 10/11/2017 – After a successful year-long test campaign by
Airbus at IABG in Ottobrunn near Munich, the twin GRACE-FO (Gravity Recovery and
Climate Experiment Follow-On) satellites will soon travel to their launch site in California.
During testing, the gravity-measuring satellites, which will track the continuous movement of
liquid water, ice and the solid Earth due to Earth's changing seasons, weather and climate
processes, earthquakes and even human activities, were subjected to conditions similar to
those they will experience during launch and in low Earth orbit. Both satellites, each weighing
600 kilograms, will be flown to the Vandenberg Air Force Base launch site in California in
December to begin final launch preparations.
The project is a partnership between NASA’s Jet Propulsion Laboratory, located in
Pasadena, California, together with the German Research Centre for Geosciences (GFZ,
Potsdam). Both GRACE-FO research satellites will be launched into a polar orbit at an
altitude of around 500 km and at a distance of 220 km apart. Both satellites will then take
continuous, very precise measurements of the distance variations between each other and
make monthly maps of the changes in Earth’s gravitational field, which are used to track the
monthly movement of liquid water, ice and the solid Earth.
The launch of the GRACE-FO twin satellites is planned for spring 2018 on a mission planned
to last at least five years.
A Global Positioning System and a microwave ranging system measure the distance
between the satellites to within a few microns and a sensitive accelerometer accounts for
non-gravitational effects, such as atmospheric drag and solar radiation. The GRACE-FO
satellites will also feature an additional element: a new, more precise inter-satellite laser
ranging instrument, developed by a German/American joint venture, which will be tested for
use in future generations of gravitational research. Each satellite also makes up to
200 profiles of temperature distribution and water-vapour content in the atmosphere and the
ionosphere on a daily basis to aid weather forecasting.
The German/American GRACE satellites, which have been in space since 2002, are the only
satellites that have been capable of monitoring the transport of mass within the Earth system.
These include changes in continental water distribution, the melting of polar ice masses or
large inland glaciers, and mass redistributions following earthquakes. Data from the GRACE
satellites are used to detect groundwater extractions, to monitor droughts and floods, to
improve hydrological models, and to precisely quantify the contribution of land glacier and
polar ice melt to sea level rise.
Long-duration data sets are vital to provide statistically significant information about climate
changes and variations. The GRACE-FO mission will continue the important job started by
GRACE and collect essential climate variables.

Dream Chaser spaceplane successfully completes glide flight and landing
Sierra Nevada Corp.’s Dream Chaser spacecraft underwent a successful free-flight test on November 11, 2017 at NASA’s Armstrong Flight Research Center, Edwards, California. The test verified and validated the performance of the Dream Chaser in the critical final approach and landing phase of flight, meeting expected models for a future return from the International Space Station.
The flight test helped advance the vehicle under NASA’s Commercial Crew Program space act agreement, as well as helped prepare the vehicle for service under NASA’s Commercial Resupply Services 2 program. The testing will validate the aerodynamic properties, flight software and control system performance of the Dream Chaser.
The Dream Chaser is preparing to deliver cargo to the International Space Station beginning in 2019. The data that SNC gathered from this test campaign will help influence and inform the final design of the cargo Dream Chaser, which will fly at least six cargo delivery missions to and from the space station by 2024.
