In meetings today the European Space Agency (ESA) has decided to upgrade Ariane 5 rather than immediately build a new Ariane 6 rocket.

Normally I would label this story as an example of “the competition heating up.” In this case, however, I don’t see how an upgrade of Ariane 5 can possibly be competitive. The rocket has been so expensive to operate that — even though it has dominated the launch market for years and is very reliable — ESA has had to subsidize its cost. It has never made a profit. I don’t see how they can reconfigure it enough to bring its cost down to compete with Falcon 9. In other words, they are trying to put lipstick on a pig.

Nor is this surprising. Arianespace is a government-run business, operated like a committee with the member nations of ESA all having a say. Under this arrangement, it is difficult if not impossible to get a quick and efficient decision. Moreover, political concerns will often outweigh issues of efficiency and profits.

In the open competitive market of privately-run companies that the launch market is becoming, I am very skeptical this kind of business can survive.

The levels of greenhouse gases in the atmosphere hit a new high in 2011.

The levels of greenhouse gases in the atmosphere hit a new high in 2011.

The atmospheric concentration of carbon dioxide (CO2) – the single most important greenhouse gas – reached 390.9 parts per million in 2011 and is now 40% above the pre-industrial level of 280 ppm, the WMO reports in its new Greenhouse Gas Bulletin released today. Methane (1,813 parts per billion) and nitrous oxide (324 parts per billion) — both potent greenhouse gases — also reached new highs last year.

Mysteriously, however, there has been no measured rise in the temperature of the climate for the past sixteen years, even though every computer model predicted that this increase in greenhouse gases would force a temperature rise.

The conclusion? I have none, other than to point out once again that climate science remains a difficult and complex area of research, filled with large gaps in knowledge and many questions and uncertainties that remain unanswered.

However, we will never get these questions answered if we make believe they don’t exist. It is essential that the climate science community stop pretending that they know what is going on while simultaneously playing politics with the science. Do the research, ask the right questions, and focus on what we don’t know. And tell the politicians to shut up and keep out, as they are surely the last people to understand the science of climate.

That way, we might finally begin to understand what is happening and can deal with it rationally.

“Long-term budget pressures on NASA mount.”

Why SLS will surely die: “Long-term budget pressures on NASA mount.”

Whether the cheaper, more efficient, and competitive commercial space program will survive remains unknown. It could be that our brilliant Congress, which wants SLS, will keep that very expensive program alive just long enough to choke the life out of the commercial space program. Then, with the government part of private space dead from lack of support, they will suddenly be faced with the gigantic bill from the NASA-built SLS and will, as they have done repeatedly during the past four decades, blanch at paying the actually construction and launch costs, and will kill that too.
