Space Mountain at Hong Kong Disneyland was the fifth version of the outer space-themed enclosed roller coaster in Disney parks. The newest Space Mountain (not counting the four recent refurbishments of the Disneyland, Disneyland Paris, Tokyo Disneyland, and Magic Kingdom) is based on the refurbished Space Mountain at Disneyland, with a similar soundtrack and the same layout. It also features new show elements not presented in the refurbished California version (i.e. a "hyperspeed" tunnel). It didn't feature the Rockin' Space Mountain configuration that was featured in Disneyland's Space Mountain in 2007.
Unlike most Space Mountains, the boarding area for the attraction is quite small. Not present is a Space Station of its two most similar counterparts at Disneyland and Tokyo Disneyland. Instead a dark queue featuring neon earth-tone colored planets along with star patterns decorate the area. Lining the walls of the station are colored neon light bars that are used for lighting and decoration.
It is the only Space Mountain to feature Single-Rider alongside its regular standby and FASTPASS lines.

As part of Hong Kong Disneyland's Haunted Halloween event from 2007 to 2013, Space Mountain went under a Halloween overlay.

In 10th anniversary celebration, Space Mountain has transformed into Hyperspace Mountain with a Star Wars theme to go alongside it.
Before the rocket takes off, this ride has a mission control with a person giving out safety instructions:
- "Space travelers, for your safety, please remain seated with your hands, arms, feet, and legs inside the rocket and supervise children. You are cleared to go." It says the same thing in Cantonese before this, and Mandarin after this. (2005–present)
In the line before entering the station this spiel plays:
- "Welcome, space travelers. Space Mountain is a thrilling, high speed, turbulent roller-coaster type ride in the dark that includes sharp turns, sudden drops & stops. Before you embark on your adventure, please place all hats, glasses, and loose possessions inside the storage pouches located directly in front of you. To prepare for launch, pull the lap bar toward you. You are now ready for your intergalactic adventure, thank you and have a great flight." This is played in Cantonese, English and Mandarin continuously. Cantonese and English version are done by the same man while Mandarin version is done by a woman.
