OSLO (Reuters) - German startup Isar Aerospace said on Monday it has postponed the launch of a space rocket from Norway due to adverse weather conditions and will try again at a later time.

The Spectrum rocket is intended to become the first orbital flight to originate from Europe, where several nations, including Sweden and Britain, have said they want a share of a growing market for satellite launches.

"The first test flight of Spectrum is scrubbed due to unfavourable winds ... the team is working to determine a new launch window," Isar Aerospace said in a statement.

Set to take off from Norway's Arctic Andoeya Spaceport, the Spectrum is designed for small- and medium-sized satellites weighing up to one metric tonne, although it will not carry a payload on its maiden voyage.

The company has warned that the initial launch may end in failure and that more attempts may be needed to reach orbit.
