India's new rocket will test 'Crew Module'
The GSLV-Mk III is a launch vehicle currently under development by the Indian Space Research Organization (ISRO). GSLV-Mk III is conceived and designed to make the ISRO fully self reliant in launching heavier communication satellites of INSAT-4 class, which weigh between 4,500 and 5,000 kilograms. It would also enhance the capability of the country to be a competitive player in the multimillion dollar commercial launch market. The vehicle will have a multimission launch capability for geosynchronous transfer orbit, low earth orbit, polar and intermediate circular orbits.
The GSLV-Mk III is designed to be a three-stage vehicle 42.4 meters tall with a liftoff weight of 630 tons. The first stage
comprises two identical S200 Large Solid Boosters with 200 tons of
solid propellant that are strapped to the second stage, the L110
restartable liquid stage. The third stage is the C25 LOX/LH2 cryo
stage. The payload fairing measures five meters in diameter.
The GSLV-Mk III is scheduled for liftoff at 11:00 p.m. EST Wednesday.

NASA software shows promise in improving aircraft flight efficiency
NASA researchers Friday began flight
tests of computer software that shows promise in improving flight
efficiency and reducing environmental impacts of aircraft, especially
on communities around airports.
Known as ASTAR, or Airborne Spacing for
Terminal Arrival Routes, the software is designed to give pilots
specific speed information and guidance so that planes can be more
precisely spaced, enabling pilots to fly a "follow the leader"
approach to their destination airport.
This type of approach would minimize
flight path deviations, allow more efficient use of existing airspace
and possibly reduce noise over communities surrounding airports –
all of which could lead to reductions in commercial flight delays.
The software is being tested on
the Boeing ecoDemonstrator 787 Test Airplane as part of The
Boeing Company’s ecoDemonstrator Program, a multi-year effort that
aims to identify and accelerate the development and testing of new
technologies and methods that can potentially reduce the
environmental impacts of aviation.
During the flight tests, NASA engineer
Roy Roper operates ASTAR on a laptop in the rear of the aircraft. As
a second aircraft flies in front of the ecoDemonstrator 787, ASTAR
computes and displays the speed required to follow safely behind.
Roper then communicates those speed commands to the ecoDemonstrator
787 pilots.
The ASTAR experiment is the first of
several NASA tests flying aboard the ecoDemonstrator Test Airplanes.
During the spring and summer of 2015, the ecoDemonstrator 757 Test
Airplane will host two NASA experiments. The first involves using
active flow control technologies on the aircraft's tail to determine
if future tail designs can be altered to reduce drag. The second will
test the effectiveness of coatings applied to the leading edge of a
wing section to reduce turbulence-inducing buildup of insect residue.
EVA Air plans non-stop flights between Taipei and Houston
EVA Air will initiate non-stop flights
between Taipei and Houston's George Bush Intercontinental Airport on
June 19, 2015. The airline will start the new service with three
flights a week and increase frequency to four on July 1, 2015. The
route will give passengers a comfortable way to fly from the
Southwestern region of the United States to Taipei and, with just one
easy stop, connect onward to major destinations throughout Asia,
including Mainland China, Singapore and Vietnam.
EVA
will serve the route with a brand-new Boeing 777-300ER equipped with
Wi-Fi, the latest inflight entertainment system and SMS roaming
service that passengers can use to send and receive short messages on
their own mobile phones. The aircraft is scheduled for delivery in
May 2015 and will be specially painted nose-to-tail with Texas-sized
Hello Kitty and Sanrio characters. It will have 333 seats, configured
with 39 in Royal Laurel Class business, 56 in Elite premium economy
and 238 in Economy.
New Canadian airline orders five Boeing 737 MAX 7s
The Boeing Company and Jetlines
announced an order for five 737 MAX 7s on Monday as the new Canadian
ultra-low cost carrier builds its future fleet. The order, valued at
$438 million at current list prices, includes purchase rights for an
additional 16 737 MAXs.
The new airline, headquartered in
Vancouver, British Columbia, plans to tap into passenger demand by
offering low cost airfares on routes that avoid direct competition
with other airlines.
The 737 MAX incorporates the latest
technology CFM International LEAP-1B engines, Advanced Technology
winglets and other improvements to deliver the highest efficiency,
reliability and passenger comfort in the single-aisle market. The 737
MAX 7 will be capable of flying more than 3,800 nautical miles,
extending the range over today's 737-700 by approximately 400
nautical miles (741 kilometers).
With this order, the 737 MAX has orders for 2,562 airplanes from 55 customers worldwide.

Video: Chinese helicopter lands on U.S. guided-missile destroyer
A Chinese Harbin Z-9E helicopter
practices landing aboard the U.S. Navy's guided-missile destroyer USS
Sterett (DDG 104). Sterett and ships from the Chinese People's
Liberation Army (Navy) commenced a bilateral counter-piracy exercise,
U.S.-China Counter-Piracy Exercise 15, in the Gulf of Aden and the
Horn of Africa.
Aiming to promote partnership, strength and presence, the exercise includes combined visit, board, search, and seizure operations, communication exchanges, and various other aspects of naval operations.

Satellite data shows MH370 plane crashed into the Indian Ocean
Critical days were lost in the search
for MH370 because Malaysian authorities initially rejected evidence
from a British satellite company that the Boeing 777 with 239 aboard
was in the Southern Indian Ocean.
British sources told AirlineRatings.com Editor Geoffrey Thomas that within 24 hours of the disappearance of MH370 on March 8, Inmarsat, a satellite communications company based in the United Kingdom, advised the relevant Malaysian authorities of their findings but were rebuffed.
Inmarsat then approached the U.K. Air Accidents Investigation Branch (AAIB) with its data and it immediately recognized the significance.
Inmarsat was contracted to provide a data link to the Malaysian Airlines fleet and continued to get a signal every hour from MH370 till 8.19 a.m. Perth time.
The Malaysian authorities were forced to take the findings seriously when the AAIB teamed with Inmarsat to represent the data around March 14 - five days after the Boeing 777 disappeared.
