So you could put up a bunch of satellites that may fail and crash into each other and destroy an orbit. There is no way to fix that. Publicerat ArianeGroup ska bygga en ny version av Arianeraketen.
The payload mass was kg and an Aerostar SF In a similar experiment flew from Esrange to Norilsk in Russia in a circumpolar flight that lasted 2 weeks. That balloon mission was called PoGOLite. Observations were conducted from a stabilized stratospheric balloon platform at an altitude of approximately 40 km.
The primary targets were the Crab — a pulsar and associated wind nebula in the constellation of Taurus, light years from Earth, and Cygnus X-1 — a black hole binary system.
A custom attitude control system kept the polarimeter field-of-view aligned to targets of interest, compensating for sidereal motion and perturbations such as torsional forces in the balloon rigging.
After a launch at A slower than anticipated wind took the balloon over the Atlantic for a landing in Canada on July 18th at Landing latitude was The mission was very successful with all systems both scientific and support and balloon systems working nominal during the complete flight.
A huge amount of scientific data was collected during the flight that are analyzed. The landing and recovery was performed nominal and the scientific data were recovered and delivered to the science team within 12 days after landing. The mission was managed by SSC and SSC was also responsible for the gondola structure, housekeeping and communication systems, power systems and of the balloon flight systems.
SSC was handling the launch, flight and recovery operations. KTH was responsible for the instrument, X-ray polarimeter, including all subsystems for controlling and monitoring the systems including thermal management.
DST Control was responsible for the dual axis pointing system.
The PA for the Crab nebula is observed to be consistent with the projection of the pulsar spin axis in the plane of the sky, compatible with an origin in the toroidal magnetic field.
It is tentatively confirmed that optical polarization data near the pulsar can be used as a proxy for higher energy emission when constructing pulsar models.Europe’s leading and Independent Enterprise Data Conference, co-located with the BI and Analytics Conference Europe.
