Astra Space Inc. is targeting no earlier than June 12, pending issuance of a launch license from the Federal Aviation Administration, for the first launch of NASA’s Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS), a constellation of six CubeSats. Two CubeSats, each about the size of a loaf of bread, will launch aboard Astra’s Rocket 3.3 from Space Launch Complex 46 at Cape Canaveral Space Force Station in Florida.
TROPICS will study tropical cyclones like hurricanes, some of the most powerful and destructive weather events on Earth, by measuring storm characteristics with a sensor about the size of a coffee cup. The miniaturized microwave radiometer detects the thermal radiation naturally emitted by the oxygen and water vapor in the air. TROPICS has the potential to provide near-hourly observations of a storm’s precipitation, temperature, and humidity. This data can help scientists increase understanding of the processes driving rapid changes in storm structure and intensity, which will improve weather forecasting models.
Astra will launch the other four TROPICS CubeSats in two separate launches later this summer.
The TROPICS team is led by Principal Investigator Dr. William Blackwell at Massachusetts Institute of Technology’s (MIT) Lincoln Laboratory in Lexington and includes researchers from NASA, the National Oceanic and Atmospheric Administration (NOAA), and several universities and commercial partners. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, will manage the launch service.
Flight data from NASA spaceflight Forum
There something strange in data 104-113 second after launch the LV0010 first stage accelerate faster as normal
it just after Max-Q, but oddly they not reduce thrust before Max-Q
The Deep droop after stage separation is normal the second stage, driftet some seconds until engine ignited.
