Astra found out the reason behind the rocket’s lateral hover and launch failure

this will be Astra’s fifth attempt to enter orbit with its rocket from Kodiak, Alaska. The company first tried to put its aircraft into orbit for DARPA’s launch challenge in March 2020, but failed to launch the rocket in time. A few weeks later, the aircraft exploded on its launch pad. After that, Astra made three more attempts in 2020 and 2021. The rocket did fly. The first launch lasted about 30 seconds. Then the rocket engine was cut off and the aircraft fell back to the earth. The second flight did reach space, but did not complete the orbit

on August 28, 2021, Astra’s third attempt attracted people’s attention with its strange actions. After takeoff, the rocket briefly slid off the ground and swept aside after one of its five main engines shut down early. Then, the aircraft climbed into the sky a few seconds later, reaching a maximum altitude of 31 miles, and then the pilots terminated the launch after 2 minutes and 30 seconds. Astra said that the leakage of rocket propellant led to the early cut-off of the engine, which “we have not seen before”. The company claims to have made some design changes to ensure that the same failure does not occur again

“the data from the two and a half minute flight provides valuable insights, and we have incorporated its changes into lv0007 and future launch vehicles,” said Chris Kemp, founder and CEO of Astra

Astra’s launch failure occurred less than two months after the company was successfully listed through spac merger. The company’s shares fell sharply on Monday after a failed launch attempt. In September, Astra reached a $30 million deal with its rival launch company firefly aerospace, which will enable the company to continue to produce firefly’s Reaver rocket engine. Astra’s ultimate goal is to launch small satellites with its rockets, which are only 43 feet tall

the company’s next launch in Kodiak, Alaska will launch a test payload for the space test program. The launch window of the mission will open for the first time on October 27 and end on October 31. If the rocket does not fly during this period for some reason, the company can try again at another window from November 5 to November 12
