1974-070A
The Astronomische Nederlandse Satelliet (Astronomical Netherlands Satellite, ANS) was the first Dutch national satellite, studying UV and X-ray astronomy. It was built by the ICANS consortium (Fokker/Phillips) for NIVR in a joint project with NASA, and operated by NLR (the Netherlands Aerospace Lab) via the ESOC-Redu ground station. ANS was intended for a 510 x 560 km x 97.8 deg orbit, but the Algol first stage of the Scout D launch vehicle malfunctioned and the spacecraft was delivered to a 266 x 1775 km x 98.0 deg orbit instead.
