NASA’s TROPICS CubeSats mission is scheduled to launch today, June 12, on an Astra Rocket 3 from Space Launch Complex 46 at Cape Canaveral Space Force Station in Florida. A two-hour window opens at noon EDT.
Here’s a look at some of today’s upcoming milestones. All times are approximate:
Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 40% chance of favorable weather conditions at noon, the start of today’s launch window, with the forecast dropping to 10 percent favorable later in the afternoon.
The primary weather concern at the start of the launch window is a Cumulus Cloud Rule violation. Later in the launch window, concerns include Surface Electric Fields and Lightning rules.
TROPICS mission aims to improve observations of tropical cyclones. Six TROPICS satellites will work in concert to provide microwave observations of a storm’s precipitation, temperature, and humidity as often as every 50 minutes.
Launch day has arrived for NASA’s commercial partner Astra. A pair of small satellites wait atop Astra’s Rocket 3 for liftoff from Space Launch Complex 46 at Cape Canaveral Space Force Station in Florida. This mission will send two-shoebox sized CubeSats to low-Earth orbit. A two-hour launch window opens at noon EDT.
This is the first of three planned launches for NASA’s Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission. Together the three launches will attempt to place six satellites in three different orbital planes to study the formation and development of tropical cyclones, making observations more often than what is possible with current weather satellites. The six TROPICS satellites will join the TROPICS Pathfinder satellite, which is already in orbit.
The six TROPICS satellites will maximize their time over the part of the Earth where tropical cyclones form and will work in concert to improve observations of tropical cyclones. The spread of the satellites means that a satellite should pass over any spot in an area stretching from the Mid-Atlantic region of the United States to the southern coast of Australia about once an hour. TROPICS will provide data on temperature, precipitation, water vapor, and cloud ice by measuring microwave frequencies, providing insight into storm formation and intensification. This new data, coupled with information collected from other weather satellites, will increase understanding of tropical cyclones and improve forecasting models.

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.
