Or The Space Game, by ESA.

The Space Game Screenshot

Minimize delta vee by moving the planets around (this changes the probe's arrival time at the planet). This shows my best solution so far, with some playing one evening, about 13 km/s

This is a nice javascript webpage where a probe is shot from Earth to Jupiter with gravity assists at Venus (twice), Earth and Mars. You try to achieve the lowest propulsive delta vee. You decide when the spacecraft arrives at each encounter and the program basically calculates the rest. It’s quite a nifty little piece of Javascript, the future of web applications is like this. It works fine with Chrome on Linux at least. Probably IE will have problems but who uses that anyway?

I’m ranked at #39 at 12.74 km/s… Far behind the gurus who get below 10 km/s readings! There are apparently some prizes for the top three, but I think people are in it for the fun of it.

I’m quite that just right now. It will pass. Perhaps.

There’s been some discussion in various places about both NASA and potential future launch vehicles. Everything’s just so static in a large sense. Completely hopeless. I’ll throw in the towel for now.

Almost nobody has the required long attention span or patience to make any useful progress on the space front, and certainly not society itself.

The Players

USA is the only instance that is putting any significant money into doing anything new. And that’s wasted on the Ares rockets. ESA consists of a bunch of bickering countries, they’ve achieved some nice things but most of the people in the parttaking countries don’t even know they exist. No significant money spent on doing anything new, and what is done in Europe, is very often just me-too copying of American approaches. (Take Hermes as an example.) India is running with some crazy hypersonic stuff. China is doing intermittent Soyuz copy PR flights. Japan is doing something overcomplicated and abortive like they have always seemed to.

What are we left with? A bunch of US newspace companies with so little funding they won’t reach much in the next decade (Euro real newspace like SPL has zero funding at the moment). Scaled’s Spaceshiptwo is a dead end propulsion wise with the hybrids, and the air launching provides some scalability problems too. Maybe XCOR’s Lynx will fly some tourists to some altitude, and maybe there might be some X-racers. It won’t change stuff radically. The X-15 lessons were tossed to the trashbin too, to make way for the farces of NASP and X-33. Armadillo might fly something newish. So what? They don’t have enough money to even put turbopumps on the vehicle, resulting in ridiculous performance for orbital missions.

SpaceX? Forget it. It’s a rerun of Orbital Sciences Corporation, at best (and at the moment it looks much worse). No revolution, and evolution only very slightly.

COTS? Maybe something will actually fly, as it seems it has to try to pick up the mess that NASA put itself in with Ares and Orion. I’m not so well versed into the coming phases and how the politics will go. Both Lockmart and Boeing are in Ares/Orion so they don’t have such strong incentives to replace it with their own COTS solution flying on EELV on the short term. Depending how tightly they can keep their own ULA/EELV guys on a leash, and that has been shown to be ugly, people having gotten into trouble for what they have said on some web forums. NASA’s logical short term COTS alternative, a capsule on an EELV is thus self-censored.

But all this, even when happening in a good way, won’t change price to orbit significantly or enable real spacefaring.

What You’d Need

You’d need a refuel and go again reusable launch vehicle (RAGA RLV) that has turbopumps. No newspace company has money for that (and they are wisely using their little money on something else anyway). Besides, you’d in any case need multiple X-vehicles to develop the techniques like TPS or launch infrastructure and procedures to maturity so they could be operated with reasonable crew size and consistency. A launcher could be depended upon.

Human societies don’t seem to have capability to demand long term commitment to that technology development.

Environment Analogy

Same with the environment. If oil prices stay above 100 dollars, coal based petroleum will come soon and the synthesis already will produce massive amounts of CO2. New coal plants will be built too to produce cheap electricity to consumers who want it. Earth will change significantly with the resulting temperature rise.

No significant new energy producing or saving technology or international pacts will be seriously considered, never mind put into effect in the next ten years.

P.S. This post was written with the new Firefox 3. Hope it doesn’t muck up during publishing. Happy Midsummer. Looks to be rainy here.

First ATV nearing ISS

The first European Autonomous Transfer Vehicle is nearing the International Space Station as I write this. It’s demo day 2 and it will go to 250 meters distance. Docking will be a few days later.

ESA has a live blog here.

NASASpaceflight.com has a live thread here. Someone just posted a screen capture:

ATV nearing ISS

There’s video at NASA TVas well as ESA’s blog.

Hope all goes well. This is a bit of a competence test for ESA and the European space industry (well, those who are in this project).

This is also important from the COTS point of view – possible new craft supplying ISS for NASA.

And of course propellant depots which require rendezvous and docking or berthing.

EDIT: apparently it came to a distance of just a few meters. Here’s a pic from NASA TV snapped to the thread on NASASpaceflight.com:

ESA’s Architecture for Exploration Study (AES) is overviewed in Lunar Base Quarterly 1/2008 (EDIT: to be clear, the Quarterly was released in January):

Lots of Ariane 5, Angara and Soyuz launches with space docking, a space station in Earth-Lunar L1 and many new crewed and non-crewed craft and capabilities.

They had a red team / blue team approach at this point.
