While driving down Interstate 5 through Santa Ana, California, you may have spotted this rocket. Even for space fans, identifying this vehicle may be difficult. It is a rare Delta Cryogenic Second Stage (DCSS) for the short lived Delta III rocket. This DCSS has a home at Discovery Cube Orange County, where she acts as an effective billboard for this educational museum. This equipment is appropriately placed near Huntington Beach where this particular payload fairing was manufactured.
On August 27, 1998, the Delta 259 mission lifted off from Launch Complex 17B at Cape Canaveral Air Force Station in Florida, marking the first flight of a Delta III, carrying the Galaxy 10 communication satellite. During the burn of its first stage, a design flaw in the rocket’s guidance system caused it to violently diverge from its planned trajectory and begin to break up. During the breakup process, the flight termination system was activated by the range safety officer, causing what was left of the rocket to explode. The Galaxy 10 satellite could be seen that night as a flaming ball streaking down until it spectacularly exploded as it hit the Atlantic Ocean.
The second flight of a Delta III would take place on May 5, 1999, as the Delta 269 mission flew from the same pad. Thanks to a manufacturing flaw in the Pratt & Whitney RL10B-2 engine, the second stage burn was cut short, causing the stage to tumble into a useless orbit. The Orion 3 communication satellite was written off and a second payload was lost.
A final flight of the Delta III would take place on August 23, 2000, with the Delta 280 mission, which carried a dummy payload called DM-F3. This time, the flight was a success, but it was too late for the Delta III. The commercial satellite industry took a steep dive in the late 1990s. The more powerful Delta IV was just a few years away from its first flight, and Boeing was pursuing a more conservative Delta II Heavy rocket. These factors, combined with the failures, caused the Delta III to be quietly shelved. Some spare parts from the program were flown on various Delta II and Delta IV flights, and in the late 2000s, Boeing donated this DCSS to Discovery Cube Orange County where it stands today, greeting passersby on Interstate 5.
The name Hạ Long is derived from the Sino-Vietnamese 下 龍, meaning “descending dragon”. According to local legend, when Vietnam had just started to develop into a country, they had to fight against invaders. To assist the Vietnamese in defending their country, the gods sent a family of dragons as protectors. This family of dragons began spitting out jewels and jade. These jewels turned into the islands and islets dotting the bay, linking together to form a great wall against the invaders. Under magics, numerous rock mountains abruptly appeared on the sea, ahead of invaders’ ships; the forward ships struck the rocks and each other. After winning the battle, the dragons were interested in peaceful sightseeing of the Earth, and then decided to live in this bay. (x)
