Delayed a 12 months by a launch failure, the coronavirus pandemic and a stretch of stiff higher stage winds this summer time, an Italian-made Vega rocket vaulted into orbit from French Guiana on Wednesday night time and deployed 53 small satellites from 13 nations to punctuate a flawless return to flight mission.
The rideshare launch set a file for essentially the most satellites ever flown on a European rocket, and helped validate course of modifications launched to resolve the issue on the Vega’s second stage that induced a failure on the launcher’s earlier mission.
The 98-foot-tall (30-meter) rocket lit its solid-fueled first stage at 9:51:10 p.m. EDT Wednesday (0151:10 GMT Thursday), instantly boosting the Vega launcher away from the European-run Guiana Area Middle on the northern coast of South America with almost 700,000 kilos of thrust.
Heading north into a transparent late night time sky, the Vega rocket flew downrange over the Atlantic Ocean and shed its first stage round two minutes after liftoff.
The Vega’s second and third stage Zefiro 23 and Zefiro 9 motors ignited to proceed the climb into orbit, adopted by 4 burns of the rocket’s liquid-fueled AVUM fourth stage to put the 53 payloads into two distinct polar orbits 320 miles (515 kilometers) and 329 miles (530 kilometers) above Earth, every tilted at an angle of about 97.5 levels to the equator.
“For Europe, it’s the very first time we’ve organized a so-called rideshare mission,” mentioned Giulio Ranzo, CEO of Avio, the Italian firm that builds a lot of the Vega rocket. “We’re very blissful for this to open up the brand new marketplace for small satellites for Europe.”
The solid-fueled Zefiro 23 second stage on Wednesday night time’s mission included enhancements designed to handle a structural deficiency that led the destruction of a Vega rocket on its earlier launch in July 2019.
The failure final 12 months induced the rocket and its payload — Falcon Eye 1 navy reconnaissance satellite tv for pc for the United Arab Emirates — to crash again to Earth within the Atlantic Ocean north of French Guiana.
Avio mentioned an unbiased investigation into the July 2019 launch failure concluded super-hot gasoline from burning stable propellant impinged on the construction of the Vega rocket’s Zefiro 23 second stage, leading to a “thermo-structural failure” on the second stage’s ahead dome.
The recent gasoline, which burns at greater than 5,000 levels Fahrenheit (Three,000 levels Celsius), broken or burned by the carbon fiber construction on the second stage. The structural failure led to the in-flight breakup of the launch car with the UAE’s Falcon Eye 1 spy satellite tv for pc.
Based on Ranzo, Avio’s CEO, investigators decided a “manufacturing anomaly” slipped by Avio’s high quality management checks.
“We had thermal safety (on the second stage) the place the thickness was maybe lower than one millimeter quick, so we had a really, very tiny deviation that was undetectable to all the standard checks,” Ranzo mentioned in March throughout an interview with Spaceflight Now.
“So what we now have carried out is we now have tremendously improved the applied sciences to permit for the manufacturing qc — utilizing not solely ultrasound but in addition digital radiography — in a a lot finer means with respect to work we used to do previously,” Ranzo mentioned.
Avio pulled from the corporate’s Zefiro 23 manufacturing line in Italy, ran it by the improved high quality management checks, and efficiently test-fired the rocket motor at a take a look at web site in Sardinia.
Ranzo mentioned Avio additionally added additional thermal insulation on the Zefiro 23 second stage motor.
“It’s most likely not essential, however we elevated the protection margin,” he mentioned in March. “So we are actually approaching the flight with a lot better consolation with respect to security.”
Engineers additionally modified components of the Vega’s telemetry, flight security and self-destruct gadgets, Ranzo mentioned.
An unbiased investigation panel issued 20 suggestions, together with 14 obligatory motion gadgets that had been applied earlier than the return to flight mission Wednesday night time.
The modifications made the Vega rocket “much more strong,” mentioned Roland Lagier, Arianespace’s chief technical officer.
The 53 spacecraft deployed by the Vega’s AVUM higher stage come from 21 clients in 13 nations, together with European Area Company member states, the USA, Canada, Argentina, Thailand and Israel.
