NASA lost two small satellites on Sunday after a rocket did not work properly on its way into orbit. The two CubeSats TROPICS were the first pair of a six-satellite constellation designed to study tropical cyclones, but the space agency is still waiting to launch the remaining four, pending an investigation into the failed delivery.
The private space company Astra’s Launch Vehicle 0010 left Cape Canaveral, Florida, at 13:43 ET, carrying a pair of satellites the size of a shoebox. The launch was delayed by almost two hours as ground crews worked to make sure the liquid oxygen propellant was at the right temperature. Shortly after launch, the rocket’s upper stage closed prematurely, preventing it from delivering its cargo into Earth orbit.
“Although today’s launch with Astra did not go as planned, the mission provided a great opportunity for new launch and science capabilities,” wrote Thomas Zurbuchen, associate administrator of NASA’s science division. on Twitter. “Earth-based business missions like this are low-cost opportunities to send #NASAcience into space. It also allows for more opportunities for researchers to gain access to space,” he added.
CubeSats were part of the structure of NASA’s time-resolved precipitation observations and the intensity of the storm with a constellation mission of small sats (TROPICS), which is designed to study tropical storms as they they are formed and developed all over the world. TROPIC satellites were intended to be spread over three orbital planes in order to cover more parts of the world at a faster rate than current meteorological satellites.
The mission is part of NASA’s Earth Adventure Program, defined as “lower cost and more risky missions.” Astra was founded in 2016 with the goal of launching small, cost-effective rockets into space, but its rockets do not always complete the journey; the California-based company has now experienced five failed seven-attempt orbital launches, according to SpaceFlightNow. In February, NASA’s first launch with Astra ended in failure after the vehicle malfunctioned before reaching orbit, resulting in the loss of four CubeSats. This latest setback has led to two failed launches for the NASA-Astra partnership.
The remaining four TROPICS CubeSats were scheduled to launch in July, but NASA said it would “stop the launch effort with Astra while an investigation is underway.” That said, NASA seems determined to launch the rest of the small constellation of satellites. “Despite the loss of the first two of the six satellites, the constellation TROPICS will still meet its scientific goals with the remaining four CubeSats distributed in two orbits,” NASA wrote in a statement. “With four satellites, TROPICS will still provide improved, time-resolved tropical cyclone observations compared to traditional observation methods.”
Well, they say the third time is a charm. Hopefully the next launch of NASA with Astra will go much better.
