HEAT 1X Tycho Brahe〔(【引用サイトリンク】title=Spacecraft )〕 was the first rocket and spacecraft combination built by Copenhagen Suborbitals, a Danish organization attempting to perform the first amateur manned spaceflight. The vehicle consisted of a motor named HEAT-1X and a spacecraft Tycho Brahe. Its launch location was a floating platform named Sputnik. The rocket was test launched twice: In 2010 a power shortage caused a valve to freeze shut, which prevented launch. In 2011 the rocket was successfully launched, reaching an altitude of before the engine was remotely shut off due to a wrong trajectory. == Micro Spacecraft Tycho Brahe== The Micro Spacecraft (MSC) had a steel pressure hull, and room for one passenger. The passenger was able to view the outside through a perspex dome.〔 The occupant flew in a half-standing/half-sitting position, in order to decrease the diameter of the spacecraft. The passenger sat in a specially designed seat, and would have worn anti-G trousers to avoid blackout. The heat shield was made of floor cork. Life support would have consisted of a diving rebreather derived CO2 scrubber and breathing O2 system. Another compartment contained both the high-speed drogue parachute and the low-speed main parachutes for deceleration. The sheer volume of the MSC provided the buoyancy in the water. Pressurized nitrogen would have been used for attitude control. The attitude thrusters were part of the non-pressurized volume of the spacecraft. The first MSC was christened "Tycho Brahe 1" and its first flight was unmanned using a crash test dummy.〔(Danish Manned Spacecraft Built by Volunteers ) Retrieved 25 August 2010〕 The man-rated Tycho Brahe would have maintained the 640-mm diameter. The ship was named after Tycho Brahe, a Danish nobleman known for his accurate and comprehensive planetary and other astronomical observations, such as the 1572 supernova. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HEAT 1X Tycho Brahe」の詳細全文を読む スポンサード リンク
