1. On cosmology he generally followed Tycho Brahe, whose scheme he reproduced in diagrammatic form.

2. The HEAT 1X rocket and Tycho Brahe spacecraft stand assembled and ready to launch in an undated picture.

3. However, the launch of Tycho Brahe will be Denmark's biggest.

4. Space is extremely limited inside Tycho Brahe, though the developers say a larger version may be in the works if all goes well.

5. In preparation for the June 3 launch, Tycho Brahe is hoisted atop the HEAT-1X rocket engine in an undated picture.

6. The gardens that Brahe installed around his observatory are in the process of being restored by the Swedish government.

7. Seen from above, the spacecraft Tycho Brahe is settled onto the HEAT-1X rocket engine.

8. Named after a 16th-century Danish astronomer, Tycho Brahe (TEE-ko brah) holds one person—or, as in Friday's test flight, one crash-test dummy.

9. From Uraniborg, Brahe accurately measured the positions of 777 stars, getting a lot of legwork out of the way for future astronomers.

10. During its test flight, Tycho Brahe reached a height of 1.7 miles (2.8 kilometers), the Post reported.

11. Friday's flight gave the Tycho Brahe scientists data on what kind of g-forces and temperature changes an astronaut-pilot would experience.

12. In the Tycho Brahe craft, the astronaut-pilot (or crash-test dummy, as pictured) half-stands(), half-sits—strapped in except for his or her arms.

13. Tycho Brahe: An important Danish astronomer of the 16th century. His ground breaking research allowed Sir Isaac Newton to come up with the theory of gravity.

14. The supernova was named after the famous astronomer Tycho Brahe, who was one of the people who observed and recorded the supernova when it first appeared in the sky in November 1572.

15. The red circle in the upper left part of this image is SN 1572, often called "Tycho's Supernova" for Renaissance astronomer Tycho Brahe.

16. But it would take Johannes Kepler, building on work performed by Tyco Brahe and others, to establish a clear scientific foundation for the planets' movements.

17. I will show you here the data that Kepler had available in 1618, largely from the work done by, of course, astronomers, observers like Tycho Brahe and others.

18. Private spaceflight took one giant step forward this week when the Tycho Brahe craft lifted off atop the HEAT-1X rocket engine Friday (pictured) from a platform in the Baltic Sea.

19. For centuries, scientists thought comets traveled in the Earth's atmosphere, but in 1577, observations made by Danish astronomer Tycho Brahe revealed they actually traveled far beyond the moon.

20. In the vent of a suborbital launch, the booster would be jettisoned before Tycho Brahe spacecraft reaches zero gravity.
