Arianespace‘s upcoming Vega launch, scheduled for August 16, 2021, will orbit Pleiades Neo 4, the second, very high-resolution satellite tv for pc that’s a part of the brand new Airbus Defence and Area’s Earth Statement (EO) constellation.
Arianespace’s second Vega mission of the yr will carry off from Europe’s Spaceport in French Guiana, with the optical statement satellite tv for pc Pléiades Neo 4 and 4 auxiliary passengers.
After liftoff from Europe’s Spaceport, the Vega launcher will fly for slightly over six minutes, powered by the primary three phases. The third stage will then separate from the higher composite, which contains the AVUM higher stage, the Pléiades Neo 4 satellite tv for pc and its 4 auxiliary passengers.
The AVUM stage will ignite its engine for the primary time in a powered part lasting about eight minutes, adopted by a ballistic part lasting over 37 minutes. The AVUM stage will then restart its engine for a second burn lasting slightly minute, earlier than releasing the Pléiades Neo 4 satellite tv for pc at an altitude of 625 km.
The following two AVUM ignition phases will final 14 and 13 seconds interrupted by a 41 minutes lasting ballistic part, adopted by the discharge of the 4 auxiliary payloads. That can mark the top of mission VV19, one hour and 44 minutes and 59 seconds after liftoff.
Pléiades Neo 4, absolutely funded and manufactured by its operator Airbus, is the second out of 4 satellites of Pléiades Neo constellation, the primary one having been efficiently orbited by Vega Flight 18 on April 28, 2021. With 30cm-native-resolution, best-in-class, geolocation accuracy and twice-a-day revisit, the 4 Pléiades Neo satellites unlock new potentialities with final reactivity.
Thanks to those state-of-the-art satellites, every step of the acquisition and supply cycle presents top-level Earth Statement (EO) providers now and going ahead for the subsequent ten years.
The nineteenth mission of Europe’s Vega mild launcher will even orbit three cubesats for the European Area Company (ESA):
LEDSAT, an academic venture from the College of Sapienza taking part in ESA’s Fly Your Satellite tv for pc! program, that has been conceived to research the performances of a know-how primarily based on Gentle Emitting Diodes for the optical stand-alone LEO satellites monitoring
RADCUBE, a cubesat developed with a world consortium to exhibit miniaturized instrument applied sciences that measure in-situ the area radiation and magnetic discipline setting in LEO for area climate monitoring functions
SUNSTORM, a cubesat with an progressive photo voltaic X-ray spectrometer to detect the X-ray pulses produced by coronal mass ejections – large eruptions of many hundreds of thousands of tons of fabric from the Solar’s floor.
BRO-4, a cubesat developed by the French start-up, Unseenlabs. The spacecraft is a part of the constellation BRO (Breizh Reconnaissance Orbiter), a spectrum monitoring and electromagnetic intelligence service for maritime surveillance. The auxiliary payloads are beneath contract of SAB Launch Services.
As demonstrated by this new mission, Vega is completely suited to each business and authorities payloads. Due to its excessive efficiency and flexibility, Vega supplies the absolute best launch answer for small and medium spacecraft headed into a variety of orbits (Solar-synchronous, ballistic, switch to the Lagrange level L1, and so on.), for EO, science, training, protection and different purposes.
The Vega program is the results of the cooperation of 10 European international locations and has been developed beneath the management of ESA, with Italy (ASI) as the primary contributor and Avio Spa (Colleferro, Italy) as a first-rate contractor, answerable for all industrial operations up-to lift-off from Europe’s Spaceport. Since its maiden flight in 2012, Vega is a part of the household of launchers exploited by Arianespace.
