Celebrating 50 years since its creation, Airbus conducted a formation flight that included representatives from each of its in-production commercial jetliner families – the A220, A320, A330, A350 XWB and A380 – along with the company’s BelugaXL airlifter.

  • Title Spiral galaxy NGC 2903

  • DescriptionThe iconic appearance of a spiral galaxy is exemplified here in the form of the stunning NGC 2903, imaged by the NASA/ESA Hubble Space Telescope. It shows off whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts of gas, and dark, weaving lanes of cosmic dust.NGC 2903 is located about 30 million light-years away in the constellation of Leo (The Lion), and was studied as part of a Hubble survey of the central regions of roughly 145 nearby disc galaxies. This study aimed to help astronomers better understand the relationship between the black holes that lurk at the cores of galaxies like these, and the rugby-ball-shaped bulge of stars, gas, and dust at the galaxy’s centre — such as that seen in this image.

The industry-leading quality and efficiency of Airbus’ A320 Family – of which the A321 is a member – has been further enhanced with its new engine option (NEO) jetliner versions. For the A321neo, Airbus expanded seating capacity with optimised use of cabin space, increased exit limits and a new cabin door configuration. This “Cabin-Flex” option increased the jetliner’s maximum capacity to 244 seats, while still providing high levels of passenger comfort.

The first time we reported on the XTI TriFan 600 aircraft was in 2017. Since then, the vertical take-off & landing (VTOL) aircraft has continued to develop and recently concluded its first hover test.

On May 8, 2019, XTI Aircraft announced it successfully completed the first test flights of its XTI TriFan 600 VTOL aircraft with a 65% scale prototype. The test flights were conducted in Placerville, California. According to the press release:

“The TriFan 600 prototype completed multiple takeoffs, hover, and landings, which tested and validated the electric motors, battery power system, ducted fan propulsion, flight controls, other electrical systems and instrumentation. The aircraft was on a short tether during the tests due to its location at an airport in northern California where it was constructed. Future flights at a certified UAV test facility will be untethered in hover and will also test forward, wing-borne flight, as well as the transition phase between vertical and forward-flight modes.”

 

 

The XTI TriFan 600 is a 6-seat, hybrid-electric, fixed-wing airplane with 3 ducted fans. The fans lift the aircraft from vertical takeoff up to 340 kt (630 km/h) in cruising speed with a range of 650 nm (750 miles, 1,200 kilometers). While these last numbers are only in its VTOL formation, a straight runaway operation pushes the performance up to 1,200 nm (2,200 km, 1,380 miles).

The final XTI TriFan 600 aircraft design will measure 37.7 ft (11.5 m) of wingspan with a length of 38.7 ft (11.8 m). The 6 ft (1.8 m) diameter propellers on the 2 wings will develop 350 hp (260 kW) electric motors (two of them). Two 5 ft (1.5 m) diameter co-axial ducted propellers are in the aft fuselage, with one motor for each propeller.

After spending the better part of a year exploring Mars’ Vera Rubin Ridge, NASA’s Curiosity Mars rover has moved to a new part of Mount Sharp. Project Scientist Ashwin Vasavada gives a tour of the rover’s new home in the “clay unit,” as well as other areas scientists are excited to visit. Find out what they could tell us about watery ancient Mars versus the dry Red Planet we see today.
