ISRO gears up for taxing experiment of controlled reentry of aged satellite

The Indian Space Research Organisation (ISRO) is gearing up for an "extremely challenging" experiment of controlled re-entry of a decommissioned orbiting satellite on Tuesday. The low Earth satellite, Megha-Tropiques-1 (MT1), was launched on October 12, 2011, as a joint satellite venture of ISRO and the French space agency, CNES for tropical weather and climate studies. An uninhabited area in the Pacific Ocean between 5S to 14S latitude and 119W to 100W longitude was identified as the targeted re-entry zone for MT1, weighing about 1000 kg. About 125 kg on-board fuel remained unutilised at its end-of-mission that could pose risks for accidental break-up, an ISRO statement noted. This left-over fuel was estimated to be sufficient to achieve a fully controlled atmospheric re-entry to impact the uninhabited location in the Pacific Ocean. Controlled re-entries involve deorbiting to very low altitudes to ensure impact occurs within a targeted safe zone. Usually, large satellites/rocket

ISRO-NASA built satellite ready to be shipped to India for launch in Sept

An earth-observation satellite jointly developed by NASA and ISRO that will help study Earth's land and ice surfaces in greater detail is all set to be shipped to India later this month for a possible launch in September. ISRO Chairman S Somanath visited NASA's Jet Propulsion Laboratory (JPL) in the US state of California on Friday to oversee the final electrical testing of the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite before being shipped to India. This mission will be a powerful demonstration of the capability of radar as a science tool and help us study Earth's dynamic land and ice surfaces in greater detail than ever before, Somanath said at the formal send-off ceremony organised at the JPL which was attended by senior scientists from the two space agencies. Later this month, the SUV-size payload will be moved into a special cargo container for a 14,000-kilometer flight to the U R Rao Satellite Centre in Bengaluru. ISRO and NASA joined hands in 2014 to build the 2,80

Japan launches intel satellite to watch North Korea, improve response

Japan successfully launched a rocket on Thursday carrying a government intelligence-gathering satellite on a mission to watch movements at military sites in North Korea and improve natural disaster response. The H2A rocket, launched by Mitsubishi Heavy Industries Ltd., successfully lifted off from the Tanegashima Space Center in southwestern Japan, carrying the IGS-Radar 7 reconnaissance satellite as part of Tokyo's effort to build up its military capability, citing growing threats in the East Asia. The satellite later successfully entered its planned orbit, Mitsubishi Heavy said. The Intelligence Gathering Satellite can capture images on the ground 24 hours a day and even in severe weather conditions. Japan launched the IGS program after a North Korean missile flyover of Japan in 1988 and aims to set up a network of 10 satellites to spot and provide early warning for possible missile launches. The satellites can be also used for disaster monitoring and response. The government wil

Plane carrying 'Virgin Orbit' rocket takes off for 1st UK satellite launch

A modified jumbo jet carrying a Virgin Orbit rocket took off from southwestern England Monday, marking the first attempt to launch satellites into orbit from Western Europe. Hundreds gathered for the launch cheered as the repurposed Virgin Atlantic Boeing 747 aircraft, named Cosmic Girl, took off from Cornwall late Monday. Around an hour into the flight, the plane will release the rocket at 35,000 feet (around 10,000 meters) over the Atlantic Ocean to the south of Ireland. The rocket will then take nine small satellites for mixed civil and defense use into orbit, while the plane, piloted by a Royal Air Force pilot, returns to Cornwall. If successful, the mission will mark the first international launch for Virgin Orbit, founded by British billionaire Richard Branson. The company, which is listed on the NASDAQ stock exchange, has already completed four similar launches from California. In the past, satellites produced in the U.K. had to be sent to spaceports in other countries to ma

38-yr-old retired Nasa satellite to fall from sky this weekend, low threat

A 38-year-old retired NASA satellite is about to fall from the sky. NASA said Friday the chance of wreckage falling on anybody is very low. Most of the 5,400-pound (2,450-kilogram) satellite will burn up upon reentry, according to NASA. But some pieces are expected to survive. The space agency put the odds of injury from falling debris at about 1-in-9,400. The science satellite is expected to come down Sunday night, give or take 17 hours, according to the Defense Department. The California-based Aerospace Corp., however is targeting Monday morning, give or take 13 hours, along a track passing over Africa, Asia the Middle East and the westernmost areas of North and South America. The Earth Radiation Budget Satellite, known as ERBS, was launched in 1984 aboard space shuttle Challenger. Although its expected working lifetime was two years, the satellite kept making ozone and other atmospheric measurements until its retirement in 2005. The satellite studied how Earth absorbed and radi

France to provide two observation satellites, receiving station to Poland

France will provide Poland with two observation satellites and a receiving station under a deal sealed Tuesday in Warsaw which Poland says will help its armed forces recognise threats early. Polish Defence Minister Mariusz Blaszczak, after meeting with his French counterpart Sbastien Lecornu, announced that they approved an agreement between Airbus and the Polish Armament Agency on equipping the Polish army with two reconnaissance satellites. Blaszczak said the agreement represented a good opportunity to strengthen our capacity for the early detection of threats. The Polish Armament Agency put the total value of the deal at 575 million euros ($612 million) and said the launch of the satellites into space would be completed by 2027. The Polish Defence Ministry said that thanks to the satellites, its military will be able to obtain reconnaissance data with an accuracy of 30 centimeters (nearly a foot). Blaszczak called it an early-warning system against both military and civilian ..

US-France launch satellite to map the world's oceans, lakes, rivers

A US-French satellite that will map almost all of the world's oceans, lakes and rivers rocketed into orbit Friday. The predawn launch aboard a SpaceX rocket from Vandenberg Space Force Base in California capped a highly successful year for NASA. Nicknamed SWOT short for Surface Water and Ocean Topography the satellite is needed more than ever as climate change worsens droughts, flooding and coastal erosion, according to scientists. "We're going to be able to see things that we could just not see before ... and really understand where water is at any given time, said Benjamin Hamlington at NASA's Jet Propulsion Laboratory in Pasadena, California. About the size of an SUV, the satellite will measure the height of water on more than 90 per cent of Earth's surface, allowing scientists to track the flow and identify potential high-risk areas. It will also survey millions of lakes as well as 1.3 million miles (2.1 million kilometres) of rivers, from headwater to mouth. The satellite w
