I share your appreciation for this magnificent space observatory.

There are already satellites and space observatories at the less stable Lagrangian points.

The mission involved the first space observatory to cover the full far infrared and submillimetre waveband.

Astron, a previous space observatory based on the Venera spacecraft.

It is likely to cripple the ability of the $1.5 billion space observatory to view the depths of the universe for several years.

Many space observatories have already completed their missions, while others continue operating, and still others are planned for the future.

The project includes two space observatories, and several observational cosmology probes.

The instruments were space observatories used to conduct ultraviolet spectroscopy of stars.

All were working at a space observatory.

Then he moved to design space orbital observatories, both on board automatic probes and manned spacecraft.
