Orbital Sciences Corp Offers Up Shuttle Replacement

The Dulles, Viginia, based Orbital Scien

ces Corp. announced on Tuesday, that it had

officially submitted a proposal to the National Aeronautics and Space Administration to build a winged space vehicle for astronaut transportation to and from earth orbit once NASA’s space shuttle is retired.

The design is of the "blended lifting body" type. Its design history goes back to 2002/2003 when Orbital did a study for NASA back then. The vehicle is designed with four seats allowing room for commercial passengers.

This new vehicle would normally use the Atlas V rocket as its booster and return for a conventional landing on a runway after its mission was completed.

Lockheed Martin Corp however, is going along with a capsule sim

ilar to Apollo/Orion with parachute landing.

My personal opinion on this matter is that I hope Orbital beats the pants off of the Lochkeed Martin proposal. Does anybody remember VentureStar? I personally do not want to see our nation just turns its back to the idea of a winged spacecraft that is able to land on a regular runway.

UPDATE December 18, 2010: At the NASA Dryden space center, a 15% scale model of Sierra Nevada Corporation's Dream Chaser spacecraft design was test dropped from a helicopter.

The company's full size version is based upon NASA's HL-20 lifting body. The Sierra Nevada Corporation's (SNC) Dream Chaser is designed to carry up to seven people to the ISS and back. It will be launched vertically on a Atlas V rocket and recover horizontally on conventional runways.

Using a Bell 206B3 Jet Ranger helicopter, the model was attached to a 100-foot long cable and dropped from an altitude of 14,000 feet. Landing this time was done via a parachute. The scale model was built by a team of experts from SNC and the Research and Engineering Center for Unmanned Vehicles at the University of Colorado at Boulder (CU).

Private Sector Space Dreams

The American bureaucracy of which NASA is a part of, has by force of congressional decree and presidential inattention except in election years, become affraid to take any bold moves in manned spaceflight.

They talk a good game, the public takes it hook, line, and sinker, and nothing really ever becomes of it. The shuttle was just suppose to be a part of a shuttle-station program. Towards the end of its career, it finally did that job. But in the beginning, it was nothing more than a glorified dump truck.

And it was paid for by the American taxpayer.

Back in the 1990s, there was a chance to replace the shuttle with a newer spacecraft. The VentureStar from Lochkeed Martin or the DC-X vertical take-off/landing, single-stage to orbit spacecraft. The DC-X was a sub-scale, flight tested piece of hardware. The VentureStar was a computer animation only. Guess which one the Clinton Administration went with? That's right: VentureStar.

Then Columbia broke up on reentry.

President Bush proposed shutting down the shuttle program and replacing it with the Apollo on steroids program known as Constellation. Now President Obama will cancel even that and hope that the private sector will take over.

Well, I (slightly) agree with President Obama that it would be better for the private sector to come into its own as far as transporting folks up into Low Earth Orbit (LEO). But, the government should have kept the Constellation Program going.

I remember in a Air Force ROTC classroom in my college days, my instructor was describing the problem faced by FDR in the Pacific War. He had General MacArthur promoting a campaign that would go through the Philippines. Admiral Nimitz wanted to go straight across the Pacific to the China coast cutting the Japanese supply line in two.

President Roosvelt decided that it would be in the best interest of the war effort to go with BOTH strategys.

I submit to the reader that the same thing could have been applied to the Constellation Program. I'm on record opposing the idea of Super-Apollo, but NO American manned spaceflight program is even worse to think about.

So where this this lead us to? Private Space Industry.

In fact, I think it is going to be up to men like Bigelow and Rutan to get American civilians back up into space (without government aid). And more important, get them to the surface of the moon and back to Earth on a regular flight schedule.

Eventually, a lunar base will be built. And maybe then, NASA will get funding from Congress to lease a base on the moon.

So, are there enough deep pockets in the worldwide civilian sector to make it possible for the non-government space program to make it to the moon and Mars ? And do it before the Chinese gets there.
