PlanetSpace is a privately funded Chicago-based rocket and space travel project founded by Geoff Sheerin, CEO of the Canadian Arrow corporation and Dr. Chirinjeev Kathuria in 2005.

In February, 2007, NASA announced plans to provide PlanetSpace with requirements and specifications to provide crew and cargo flights to the International Space Station under the terms of the National Aeronautics and Space Act. Initially PlanetSpace planned to utilize the Silver Dart for this purpose,[1] but on 21 November 2007 PlanetSpace announced its COTS proposal would utilize a spacecraft provided by Lockheed Martin.[2] This proposal does not include use of the Silver Dart.[3]

Background[edit]

The mission of PlanetSpace is to make space travel accessible to the general public. The company has focused its main efforts on two major projects: the Canadian Arrow, which is[citation needed] in development,[when?] and the Silver Dart, which is a proposed orbital spaceplane.

Geoff Sheerin, President of Canadian Arrow and Dr. Chirinjeev Kathuria, two entrepreneurs with a love of space, joined forces to create PLANETSPACE in the spring of 2005. At a press conference in May 2005 in London Ontario Canada, Sheerin told the United Press International that Canadian Arrow was nearing completion and that it was missing only one important component in its plan to develop its space tourism business: money. Geoff Sheerin proudly announced, "We have found our Paul Allen". Presenting the newly formed company PlanetSpace and his new partner Dr.Chirinjeev Kathuria.

Dr. Kathuria was a founding director of MirCorp, the company that made history on April 4, 2000 when it launched the world's first privately funded manned space program and signed up Dennis Tito to space as Earth's first space tourist or citizen explorer. MirCorp was a joint venture with RSC Energia. RSC Energia launched the first satellite (Sputnik), sent the first man to orbit the Earth (Yuri Gagarin), built the Mir Space Station, and is a major partner in the International Space Station. Mir is the Russian world for World.

Canadian Arrow[edit]

Main article: Canadian Arrow

The Canadian Arrow is a 16.5 m tall two-stage rocket, where the second stage is a three-person space capsule. In a somewhat conservative approach, the design of the rocket engine and aerodynamics are based on the well proven V-2 design from WWII. The vehicle will launch vertically from the ground, on a sub-orbital trajectory, and will return to Earth via parachutes and make a water landing, similar to the splashdowns of the Mercury, Gemini and Apollo spacecraft.

Silver Dart[edit]

Based on the FDL-7, a lifting body aircraft designed for near earth orbital flight by the US Airforce Flight Dynamics Laboratory,[4] the Silver Dart was a lifting body concept[when?] designed to glide from hypersonic speeds of Mach 22 down to landing. The goal was to develop an orbital space craft/hypersonic glider capable of carrying around eight passengers. The spacecraft was expected to launch vertically atop a two-stage-plus-boosters rocket, propelled at takeoff by 28 Canadian Arrow rocket engines (slightly updated replicas of the German V-2 engine) and land horizontally on an aircraft runway, in an arrangement reminiscent of the Dynasoar project by NASA.[citation needed]

NASA based its X-24B test aircraft on the FDL-7 lifting body and valued the added range and stability the sleek, sharp-nosed design. FDL-7's lifting body design was projected to be able to give the Silver Dart about twice the lift coefficient of NASA's space shuttles at subsonic speeds. The design is expected to have a higher glide range and cross range than the Shuttle Orbiter, thus relaxing somewhat the requirements on reentry windows and thermal shielding.[citation needed] The ship was intended to use a metal skin that would be more resistant to weather conditions than the Space Shuttle according to Paul Cyzsz, an engineer with the FDL-7 program now with PlanetSpace. PlanetSpace had indicated[when?] that initial demonstration flights would have to begin in December 2009;[citation needed] in the event, when funding was not received from NASA, no full design effort was completed beyond the initial conceptual work.[citation needed]

Athena III[edit]

In early 2008,[5] PlanetSpace proposed the Athena III, a 2.8-million-pound-thrust shuttle-derived space station resupply booster rocket, in a joint venture with Lockheed Martin and Alliant Techsystems (ATK), to NASA under the phase 2 rebid of the Commercial Orbital Transportation Services (COTS) program.[5]

The PlanetSpace proposal was not accepted for NASA funding. On February 19, 2008, the second round award was made to Orbital Sciences Corporation, for the Cygnus spacecraft.[6] NASA's selection statement showed that Orbital beat PlanetSpace on funding concerns.[7]

As of October 2008, PlanetSpace, Lockheed Martin and ATK had teamed up with Boeing and the State of Florida to obtain private financing for the project outside the NASA funding they did not obtain.[8][dated info]
