SpaceX's Falcon 9 launches, releases 10 Iridium satellites into orbit

SpaceX's Falcon 9 launches, releases 10 Iridium satellites into orbit

Science
March 30 (UPI) -- SpaceX launched10 Iridium-5 Next satellites from its Falcon 9 rocket Friday at Vandenberg Air Force Base in California.The Falcon 9 blasted off at 10:13 a.m. EDT. The main engine cutoff and stage separation occurred as planned. Eight minutes after the launch, the second stage engine cutoff was confirmed.One hour after liftoff, the 10 satellites were deployed over 15 minutes in a low Earth obit. The 10 satellites are the fifth set SpaceX is launching for Iridium of a planned network of 75 satellites. The launches began in October 2017 and are scheduled to be complete in a few months. Six of the satellites will serve as on-orbit spares.SpaceX didn't attempt to recover Falcon 9's first stage after launch as it has in previous flights, but planned to attempt to catch its fair...
Satellites show warming is accelerating sea level rise

Satellites show warming is accelerating sea level rise

Technology
Melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of sea level rise, new satellite research shows. At the current rate, the world's oceans on average will be at least 2 feet (61 centimeters) higher by the end of the century compared to today, according to researchers who published in Monday's Proceedings of the National Academies of Sciences. Sea level rise is caused by warming of the ocean and melting from glaciers and ice sheets. The research, based on 25 years of satellite data, shows that pace has quickened, mainly from the melting of massive ice sheets. It confirms scientists' computer simulations and is in line with predictions from the United Nations, which releases regular climate change reports. "It's a big deal" because the projected sea level ...

Rocket lights sky as it carries satellites from California

Technology
A reused SpaceX rocket carried 10 satellites into orbit from California on Friday, leaving behind a trail of mystery and wonder as it soared into space. The Falcon 9 booster lifted off from coastal Vandenberg Air Force Base, carrying the latest batch of satellites for Iridium Communications. The launch in the setting sun created a shining, billowing streak that was widely seen throughout Southern California and as far away as Phoenix. Calls came in to TV stations as far afield as San Diego, more than 200 miles south of the launch site. Cars stopped on freeways in Los Angeles so drivers and passengers could take pictures and video. The Los Angeles Fire Department issued an advisory that the "mysterious light in the sky" was from the rocket launch. Jimmy Golen, a sports writer for The Assoc...

Science
Dec. 22 (UPI) -- SpaceX finished its busy 2017 launch schedule with a final blastoff from California.The aerospace company's Falcon 9 rocket lifted off from California's Vandenberg Air Force Base around 8:30 p.m. ET on Friday.The Falcon 9 rocket ended the year just as SpaceX began the year, delivering a 10-pack of communications satellites into low-Earth orbit for Iridium Communications.SpaceX has helped Iridium amass an impressive constellation of satellites. The company's voice and data relay network is operating across 30 satellites. Soon it will be 40.With SpaceX's continued assistance, Iridium aims to put a total of 75 satellites in space. The company has expanded services for its customers to include video and Internet capabilities alongside its standard offerings of phone, messaging...
US firm picks UK for weather satellites

US firm picks UK for weather satellites

Science
Media playback is unsupported on your deviceA miniaturised instrument to monitor the weather will be the first payload to fly on one of the UK's new publicly funded demonstration satellites. US-based Orbital Micro Systems will launch their microwave radiometer aboard the 30cm-long spacecraft next year to retrieve temperature, humidity and precipitation measurements. If successful, OMS plans a 40-strong constellation of similar satellites. OMS is moving into Britain because of the support offered to new space firms. Originating in Colorado, the company is opening a data-processing centre in Harwell, Oxfordshire, and a hardware facility in Glasgow, Scotland. "The UK's In-Orbit Demonstration programme is unique; it doesn't exist anywhere else," says OMS CEO William Hosack. "The speed with whi...
