House Asks NASA to Postpone Space Plane

PipianJ writes "The House Science Committee has requested NASA to postpone the orbital space plane program (official letter (pdf)), thanks to lingering concern about the safety of the existing space program. On the other hand, isn't one of the ideas behind the orbital space plane program the fact that our current space program is getting more unsafe through the use of 20-year-old equipment?" The Senate is also getting into the act.

saftey should be paramount, and if that isn't the case I would urge congress to put a stop all manned flights until that is the case.

No. The idea behind the prbital space plane is find a way for NASA to shovel money to a few big quasi-monopolies.

NASA's been trying to put wings on spacecraft for decades. They've spent bilions and they still don't know how to do it. There's no guarantee that a space plane will be any safer than the Shuttle. Remember, old technology didn't crash the Colombia.

There are other, cheaper, ways to get people to and from orbit. We've been able to do that, safely, for more than 40 years. Since we know how to do that, we ought to concentrate on going someplace in space (where wings are pointless, obviously) rather than some useless technical chimera like the orbital space plane.

Good! Send NASA to Mars..

Apparently Robert Zubrin, manned Mars mission advocate, is going to testify as part of this review. At the moment the US is spending $3 billion/year on the shuttle, and an unknown amount on the new OSP (Orbital Space Plane), all without any clear objective in mind. It is very hard not to feel, at least as far as manned exporation goes, NASA is floundering at the moment.

It is me worth re-posting this related extract from a piece posted on www.space.com, by Robert Zubrin - an advocate of reform in the US space program - interesting reading...

In the recent Columbia hearings, numerous members of congress continually decried the fact that the US space program is "stuck in Low Earth Orbit." This is certainly a serious problem. If it is to be addressed adequately, however, America's political leadership needs to reexamine NASA's fundamental mode of operation.

Over the course of its history, NASA has employed two distinct modes of operation. The first, prevailed during the period from 1961-1973, and may therefore be called the Apollo Mode. The second, prevailing since 1974, may usefully be called the Shuttle Era Mode, or Shuttle Mode, for short.

In the Apollo Mode, business is conducted as follows. First, a destination for human spaceflight is chosen. Then a plan is developed to achieve this objective. Following this, technologies and designs are developed to implement that plan. These designs are then built, after which the mission is flown.

The Shuttle Mode operates entirely differently. In this mode, technologies and hardware elements are developed in accord with the wishes of various technical communities. These projects are then justified by arguments that they might prove useful at some time in the future when grand flight projects are initiated.

Contrasting these two approaches, we see that the Apollo Mode is destination driven, while the Shuttle Mode pretends to be technology driven, but is actually constituency driven. In the Apollo Mode, technology development is done for mission directed reasons. In the Shuttle Mode, projects are undertaken on behalf of various internal and external technical community pressure groups and then defended using rationales. In the Apollo Mode, the space agency's efforts are focused and directed. In the Shuttle Mode, NASA's efforts are random and entropic.

Imagine two couples, each planning to build their own house. The first couple decides what kind of house they want, hires an architect to design it in detail, then acquires the appropriative materials to build it. That is the Apollo Mode. The second couple polls their neighbors each month for different spare house-parts they would like to sell, and buys them all, hoping to eventually accumulate enough stuff to build a house. When their relatives inquire as to why they are accumulating so much junk, they hire an architect to compose a house design that employs all the knick-knacks they have purchased. The house is never built, but an adequate excuse is generated to justify each purchase, thereby avoiding embarrassment. That is the Shuttle Mode.

In today's dollars, NASA average budget from 1961-1973 was about $17 billion per year. This is only 10% more than NASA's current budget. To assess the comparative productivity of the Apollo Mode with the Shuttle Mode, it is therefore useful to compare NASA's accomplishments between 1961-1973 and 1990-2003, as the space agency's total expenditures over these two periods were equal.

Between 1961 and 1973, NASA flew the Mercury, Gemini, Apollo, Skylab, Ranger, Surveyor, and Mariner missions, and did all the development for the Pioneer, Viking, and Voyager missions as well. In addition, the space agency developed hydrogen oxygen rocket engines, multi-staged heavy-lift launch vehicles, nuclear rocket engines, space nuclear reactors, radioisotope power generators, spacesuits, in-space life support systems, orbital rendezvous techniques, soft landing rocket technologies, interplanetary navigation technology, deep space data tr
