PSLV-XL C38 success2017年06月23日 17時57分


(C)ISRO

Other satellites launched Friday include a spacecraft named CESat-1 from
Japan designed to demonstrate Earth observations using Canon imaging
technology. The Max Valier Satellite, with an X-ray astronomy telescope
and an amateur radio beacon, was developed in partnership by Italian high
school students, Germany's OHB System AG satellite contractor, and the
Max Planck Institute for Extraterrestrial Physics.

Latvia's first satellite, named Venta-1, hosts digital cameras and a ship
tracking instrument. The 16.5-pound (7.5-kilogram) satellite was built by
Latvian students and funded by the Latvian government.

Eight CubeSats for the multi-national QB50 science consortium, formed by
educational institutions to conduct a wide range of research in low Earth
orbit, also headed into space Friday.

The QB50 CubeSats launched from India are the second batch of satellites
to lift off, following 28 of the compact student-built platforms which
launched in April on an Atlas 5 rocket going to the ISS.

The QB50 CubeSats launched Friday include:

  Pegasus from the University of Applied Sciences Wiener Neustadt
          in Austria
  NUDTSat from the National University of Defense Technology
          in China
  VZLUSAT-1 from universities and institutions in the Czech Republic
  COMPASS-2 (DragSail-CubeSat) from the FH Aachen University of
          Applied Sciences in Germany
  UCLSat from University College London in the United Kingdom
  InflateSail from the University of Surrey in the United Kingdom
  URSA MAIOR from the Sapienza University of Rome in Italy
  LituanicaSAT-2 from Vilnius University in Lithuania

Other payloads aboard the PSLV included the SUCHAI 1 CubeSat developed
by students and faculty at the University of Chile in Santiago.
It carries instrumentation to study the environment in low Earth orbit.

The Aalto-1 CubeSat built by Finnish university students will test a new
type of spectrometer in space, measure space radiation and demonstrate an
electrostatic plasma brake to drop out of orbit at the end of its mission.

Sponsored by the European Space Agency, the Robusta-1B CubeSat from
the University of Montpellier 2 in France will measure the effects of
radiation on satellite electronics.
