Niepowodzenie startu Electrona 04.07. o 21:19:36 z Onenui Station wystrzelona została RN Electron/Curie, która miała wynieść w T+52' 06" na
orbitę o parametrach: hp=500 km, ha=500 km, i=97,5° satelity CE-SAT-1B, pięć SuperDove Flock 4e oraz Faraday-1.
Awaria zaistniała po czterech minutach od startu na etapie pracy drugiego stopnia, w T+5' 41", rakieta osiągnęła maksymalną wysokość 194,8 km i zaczęła spadać.

Pechowa 13 Electrona BY KRZYSZTOF KANAWKA ON 5 LIPCA 2020
(...) Na pokładzie tej rakiety znalazło się siedem satelitów dla różnych operatorów. Był to trzynasty start Electrona od wprowadzenia tej rakiety do użytku. Tej start otrzymał nazwę “Pics or it didn’t happen” z uwagi na obecność satelitów obserwacji Ziemi na pokładzie tej rakiety.
Lot zakończył się niepowodzeniem. W trakcie pracy drugiego stopnia, około 4 minuty od startu, doszło do awarii. W piątej minucie i 41 sekundzie lotu częściowo urwał się kontakt z rakietą. Co ciekawe, od momentu awarii przez pewien czas reprezentanci spółki Rocket Lab informowali o poprawnych parametrów lotu. Pod koniec transmisji z rakiety można było zobaczyć, że prędkość rakiety zaczęła spadać, po czym rakieta zaczęła obniżać swoją wysokość.

In a statement Saturday, Rocket Lab said the issue that caused the launch failure occurred “approximately four minutes into the flight.” The company said the rocket stayed within its flight safety corridor, and that it is working with the Federal Aviation Administration to “investigate the anomaly and identify its root cause to correct the issue to move forward.”
The first visual evidence of a problem on Rocket Lab’s live video webcast of Saturday’s mission occurred somewhat later.
The video stream appeared to show the Electron’s second stage firing normally until the live feed from the rocket froze at T+plus 5 minutes, 41 seconds. At the same time, telemetry data displayed on Rocket Lab’s video stream showed the rocket stop accelerating at a velocity of 8,509 mph, or nearly 13,700 kilometers per hour.
An altitude display showed the rocket continue climbing for about 26 more seconds, reaching a peak altitude of 121 miles (194.8 kilometers) before descending back to Earth. The rocket and its payloads likely disintegrated and burned up once they re-entered the atmosphere.

Credit: Rocket LabThe seven satellites lost in Saturday’s launch failure were owned by Canon, Planet and a British startup company named In-Space Missions.
Canon’s CE-SAT-1B Earth-imaging spacecraft was the largest of the payloads on Saturday’s mission. The 147-pound (67-kilogram) satellite was shaped like a cube, and measures a bit larger than a dorm room refrigerator.
Its camera system was designed to be able to resolve objects on the ground as small as about 3 feet, or 90 centimeters, according to Canon. CE-SAT-1B was to be Canon’s second satellite in orbit, and the Japanese electronics company — eyeing a fleet of Earth-viewing satellites — intended to test the spacecraft’s design for future mass production.

Five SuperDove Earth observation nanosatellites from Planet were also aboard Rocket Lab’s Electron rocket Saturday. The SuperDoves were advanced versions of Planet’s medium-resolution Dove satellites, and are each about the size of a shoebox.
Based in San Francisco, Planet operates a fleet of more than 120 Earth observation satellites providing daily imaging coverage over all of the world’s landmass, providing data on changing features to governments and businesses. The five SuperDoves launched with Rocket Lab Saturday were part of Planet’s “Flock 4e” batch of nanosatellites. (...)
