UPCOMING SATELLITE MISSION MAY 'SEE' HOW EARLY UNIVERSE COOLED UPCOMING SATELLITE MISSION MAY 'SEE' HOW EARLY UNIVERSE COOLED - During the cooling of the early universe, bubbles formed in its hot plasma, triggering gravitational waves. These space ripples could be detectable even today, a new study suggests. As the early universe cooled shortly after the Big Bang, bubbles formed in its hot plasma, triggering gravitational waves that could be detectable even today, a new study suggests. For some time, physicists have speculated that a phase transition took place in the early universe shortly after the Big Bang.   More

IRIDIUM IN TALKS TO LAUNCH MORE BACKUP SATELLITES THIS YEAR IRIDIUM IN TALKS TO LAUNCH MORE BACKUP SATELLITES THIS YEAR - Iridium expects to take advantage of a rideshare opportunity this year to launch up to five of the six spare satellites it has been storing in Arizona. The satellite operator expects to make a formal announcement about the potential $35 million launch deal in “the next couple weeks,” company spokesperson Jordan Hassin said. Matt Desch, Iridium’s CEO, first disclosed plans to deploy ground spares in the company’s April 19 earnings call for the first quarter of 2022. “I want to be clear that we do not have an immediate need to launch these satellites,” Desch said. “Our constellation is very healthy and is performing well, but our ground spares have little utility just sitting in storage.”   More

SPACEX LAUNCH CADENCE MOVES FORWARD WITH 53 MORE STARLINK SATELLITES TO ORBIT SPACEX LAUNCH CADENCE MOVES FORWARD WITH 53 MORE STARLINK SATELLITES TO ORBIT - SpaceX has launched its 15th Falcon 9 of the year, lofting another batch of 53 Starlink satellites on the Starlink Group 4-14 mission. Liftoff occurred on April 21 at 1:51 PM EDT (17:51 UTC) from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station (CCSFS) in Florida. As is traditional these days, the Falcon 9 for this mission featured a flight-proven booster, B1060. This booster flew for the 12th time, being the second one in the fleet to achieve that – and just one month after B1051 became the first one to reach 12 flights.   More

WEATHER SATELLITE PREPARES FOR LIGHTNING WEATHER SATELLITE PREPARES FOR LIGHTNING - As one of the last milestones before liftoff at the end of the year, the first Meteosat Third Generation weather satellite is being fitted with its Lightning Imager. From geostationary orbit, 36,000 km above Earth's surface, this state-of-the-art European instrument will continuously monitor lightning over more than 80% of Earth's disk for early warnings of dangerous storms. Remarkably, it is capable of imaging relatively weak lightning events in full sunlight.   More
