California-based Astra on Sunday fired two NASA satellites the size of a shoebox from Cape Canaveral on a modest mission to improve hurricane forecasts, but the company’s second phase of the company’s low-cost accelerator failed before it reached orbit and lost payload. .
“The upper stage was shut down early and we did not deliver the payload into orbit,” tweeted Astra. “We shared our regrets with @NASA and the payload team. More information will be provided once we have completed a full analysis of the data. “

This was the seventh launch of Astra’s small Venture-class rocket and the company’s fifth failure. Sunday’s launch was the first of three planned for NASA to launch six small CubeSat, two at a time, in three orbiters.
Given the somewhat risky nature of CubeAats’ reliance on a small shoebox and rocket with very short experience, the $ 40 million project requires only four satellites and two successful launches to accomplish the mission’s objectives.

NASA’s contract provides for the last two flights until the end of July. It is not yet known whether Astra will meet this schedule given Sunday’s failure.
“Although today’s launch with @Astra did not go according to plan, the mission offered a great opportunity for new science and launch opportunities,” tweeted NASA Chief of Science Thomas Zurbuchen.

The launch on Sunday came and was delayed by an hour and 43 minutes, mainly to ensure that the load of the amplifier with liquid oxygen was at the right temperature. Finally, hoping to record the company’s third successful flight into orbit, Astra engineers counted down to 13:43 ET.
With its five first-class engines generating 32,500 pounds of thrust, the 43-foot 3.3 rocket moved away from site 46 of Cape Canaveral Space Station, organizing a dramatic show for locals and tourists enjoying a sunny day near beaches.
The first stage increased the payload from the lower atmosphere, passing to the single engine that powers the upper stage of the rocket.
Everything seems to be going smoothly, when about a minute before the second-stage engine was expected to shut down, an on-board “rocket camera” showed a flash in the engine’s exhaust. Their view from the camera showed what looked like a fall before the rocket video was cut.

The mission of NASA TROPICS is to monitor the development of tropical storms in near real time, flying over hurricanes and other major systems every 45 to 50 minutes and transmitting back temperature profiles, precipitation, water vapor and cloud ice data.
This ability to quickly review, that is, the time between the passage of a satellite over a storm system, aims to help scientists better understand how major storms develop and help forecasters better predict the path and intensity of the storm. .
“Measuring hurricanes from space is really difficult to do because they are very dynamic, they change in time from minutes, you have to spatially resolve all the characteristics of the storm, the eyes, the rainbows,” said William Blackwell, chief researcher at the mission. TROPICS at the Massachusetts Institute of Technology.
“Today we get maybe four or six hours before the next satellite flies. With this constellation of six Cubesat satellites … we can fly every hour. We will see how the storm changes, we will be able to better predict how it may intensify. What we are trying to do is improve our ability to predict. “
NASA is paying $ 8 million for three Astra launches and about $ 32 million for developing and testing cubesats and one year of data analysis.
The TROPICS mission poses a greater technical risk than NASA normally accepts – cubesats, while relatively inexpensive, have little surplus and the Astra 3.3 rocket has yet to demonstrate reliable performance – but officials say the potential scientific gain justifies “high-risk impact “project.
“I love TROPICS simply because it’s kind of like a crazy mission,” Zurbuchen said last week. “Think of six cubes … watching tropical storms with a repeat time of 50 minutes instead of 12 hours.”
After Sunday’s failure, he tweeted: “Although we are disappointed at the moment, we know: there is value in taking risks in our entire NASA Science portfolio because innovation is needed to be a leader.”

While NASA’s contract covers six cubic meters and their launchers, only four have to work to meet the requirements of the contract. In that case, Blackwell said, the revisit time would be about an hour. In all six in action, the interval between observations will be 45 to 50 minutes.
Putting TROPICS on what NASA calls a short-range Venture rocket made sense from NASA’s point of view.
“You’re always nervous every time you shoot, no matter what the vehicle is,” Blackwell said. But in this case, we have built-in resilience to tolerate these kinds of new opportunities. So it’s a good match between our stable mission with six satellites and only four in need, and this new capability with lower costs, fast cadence launches. “
