SpaceX successfully launches satellite

Science
July 20 (UPI) -- SpaceX launched another communications satellite during the wee hours of Sunday morning. The company's 230-foot Falcon 9 rocket blasted off at 1:50 a.m. ET Sunday. The rocket and payload, a Telstar 19 VANTAGE satellite, lifted from Launch Complex 40 at Cape Canaveral Air Force Station in Florida, the company's 13th launch of the year. The Falcon 9's first-stage booster landed on the deck of a SpaceX ship stationed in the Atlantic Ocean about 8 1/2 minutes after liftoff. It will return to Port Canaveral in a few days. Thirty-three minutes after launch, 15,500-pound Telstar 19 Vantage satellite was released. It's orbit is over the equator. Sunday morning's mission marked the second launch for the Block 5, the most advanced and final iteration of the Falcon 9. The first one...
NASA satellite spies massive iceberg parked near small Greenland village

NASA satellite spies massive iceberg parked near small Greenland village

Science
July 18 (UPI) -- The massive iceberg parked ominously outside Innaarsuit, a small village on Greenland's western coast, looks less intimidating from a few hundred miles away. That's the vantage offered this week by NASA, which posted a photo of the iceberg captured by its Landsat 8 satellite. The satellite's Operational Land Imager captured a natural color photograph of northwestern Greenland and Baffin Bay earlier this month. The image, offering a view from 435 miles above Earth's surface, shows the iceberg before it became grounded on a shallow strip of seafloor just offshore from Innaarsuit. The phenomenon is relatively common, but this particular iceberg is worryingly big, rising 300 feet above sea level and dwarfing the nearby village. And while the juxtaposition makes for good phot...
Sentinel satellite exposes sulphur dioxide pollution

Sentinel satellite exposes sulphur dioxide pollution

Science
What must it be like to live in the Siberian town of Norilsk on a "bad air day"? They say the local smelting industry produces 1% of all the sulphur dioxide (SO₂) going into the air globally, something close to two million tonnes a year. SO₂ is particularly unpleasant if breathed in; but it also washes out of the sky as "acid rain", damaging plant-life and denuding the quality of water in streams and rivers. The extent of Norilsk's pollution problem is captured in remarkable new maps from Europe's Sentinel-5P satellite. The spacecraft was put up last year to track the gases responsible for dirty air - with SO₂ being one of the prime culprits. Assembled in the UK and carrying the Dutch-led Tropomi instrument, S5P...
Satellite image shows rain puddles in the world's largest contiguous sand desert

Satellite image shows rain puddles in the world's largest contiguous sand desert

Science
June 15 (UPI) -- An image shared by NASA this week features a rare sight, rain puddles in Rub' al-Khali, the world's largest contiguous sand desert. At the end of May, the tropical cyclone Mekunu passed across the Arabian Peninsula. The port of Salalah, in Oman, received 11 inches of rain in just 24 hours -- two times the city's average annual precipitation total. The storm slowed and dissipated as it traveled inland across the desert, but still had plenty of moisture left to drop. On May 29, three days after the storm, Landsat 8's Operational Land Imager snapped a picture of the dunes of Rub' al-Khali as the satellite passed 435 miles overhead. The basins between the sand dunes can be seen filled with standing water. NASA shared the remarkable image online this week. The portion of the ...
SpaceX launches SES-12 communications satellite

SpaceX launches SES-12 communications satellite

Science
June 3 (UPI) -- [embedded content] SpaceX launched a communications satellite early Monday morning. The company's Falcon 9 rocket, with a used first stage, launched from Florida's Cape Canaveral Air Force at 12:29 a.m. Monday. The rocket will carry the SES-12 satellite to orbit for the Luxembourg-based telecom company SES. The satellite is headed for geostationary orbit, about 22,300 miles above Earth's surface, and will provide video and data services to customers across the Asia-Pacific region, SES representatives said. The launch was originally scheduled for early Wednesday morning, and then postponed again to early Friday. But the company announced the need for additional tests to the rocket's upper stage. The first stage has flown once before, in September 2017, carrying the robotic...
