More Mars Imaging to Come

MRO’s CRISM imaging spectrometer instrument has been activated. Shouldn’t be long before we start getting some really interesting information about the planet’s surface composition:

CRISM will look for areas that were wet long enough to leave a mineral signature on the surface, searching for the spectral traces of aqueous and hydrothermal deposits, and mapping the geology, composition, and stratigraphy of surface features. The imager will map areas on the martian surface as small as 60 feet (about 18 meters) across, with the orbiter at its average altitude of about 190 miles (300 kilometers).

Offering greater capability to map spectral variations than any similar instrument sent to another planet, CRISM will read 544 ?colors? in reflected sunlight to detect minerals in the surface. Its highest resolution is about 20 times sharper than any previous look at Mars in near-infrared wavelengths. By identifying sites most likely to have contained water, CRISM data will help determine the best potential landing sites for future Mars missions seeking fossils or even traces of life.

And Speaking of Branson…

…Virgin Galactic unveiled its new vehicle this week. SS2 and WK2 look like longer, skinner, larger versions of their X-Prize-winning ancestors.

I’m not sure what they were thinking with regards to the interior renderings, though. The thought of squeezing my cranium into a helmet shaped like a lightbulb kinda cuts into the appeal of a suborbital space trip.

And Speaking of Space Tourism…

…Anousheh Ansari is back from her space safari.

And apparently, space smells like a “burned almond cookie”. (At least, something in the space between the hatches in the docking adapter did.)

Virgin Galactic’s Homegrown Competition

Looks like Richard Branson may have some homegrown competition on his hands: U.K.’s Starchaser Racing Virgin to Space:

Starchaser plans to launch SKYBOLT at the end of 2007 from a launch site in the United States. If the rocket is not ready in time, it might lift off later from Sweden or even Australia.

“Once we have the rocket ready we’re going to go with the first launch site that can accommodate us,” Bennett said…

The 2007 launch of SKYBOLT will lead the way for Starchaser’s first manned trip, scheduled for 2009. The manned trip will include a capsule that will sit on top of the rocket and will carry 3 passengers on a suborbital journey to an altitude of almost 100 miles. The trip will last about a half hour…

The trip will cost a mere 98,000 United Kingdom Pounds, or about $183,000 U.S. A two and a half hour flight aboard SpaceShipTwo will run the Branson tourist about $200,000 U.S.

Bennett thinks perhaps he could beat Branson to space.

Good Riddance

It’s a pity that more scandal-ridden Congressmen (and Senators) don’t have the decency to resign immediately (or at all, in many cases) when caught: Foley Resigns From Congress Over E-Mails

Foley’s two-sentence statement gave no reason for Foley’s decision to abandon a flourishing career in Congress. But several officials said the resignation had been prompted by the e-mails, and he took his action as fresh details emerged about electronic messages he had sent…

Campaign aides had previously acknowledged that the Republican congressman e-mailed the former Capitol page five times, but had said there was nothing inappropriate about the exchange. The page was 16 at the time of the e-mail correspondence.

The page worked for Rep. Rodney Alexander, R-La., who said Friday that when he learned of the e-mail exchanges 10 to 11 months ago, he called the teen’s parents. Alexander told the Ruston Daily Leader, “We also notified the House leadership that there might be a potential problem,” a reference to the House’s Republican leaders.

On Foley’s side, this is how ugly matters like this should be handled — ideally it wouldn’t happen, but when exposed, one should simply resign. No transparent denials, no obfuscation of the matter, no shifting of blame — just take responsibility for it.

I just wonder why, if Alexander notified the House leadership about this matter “10 to 11 months ago”, they didn’t seem to do anything about it. Well, of course I know why (avoiding bad publicity, or just avoiding the issue itself out of squeamishness), but one would think they’d know that something like this would come out eventually…most likely right before the election, when it could do the most damage.

Whatever the House leadership may have been doing about it behind the scenes (if anything), taking so long and still not reaching a resolution indicates poor leadership on Hastert’s part. The evidence available clearly shows that Foley was ethically compromised, even if his contacts with the boy had not (yet) culminated in any criminal acts…what more “investigation” would be required than to verify that the email messages were authentic?

Good riddance, though, even if Foley’s departure wasn’t as prompt as it should have been. Given the nature of the place and the political environment this season, I have to wonder if there aren’t more Congressional scandals like this ready to erupt over the next month. This may just be an appetizer for a full month of October surprises.

ADDENDUM: An interesting detail in the A(wt)P story is that an organization named Citizens for Responsibility and Ethics in Washington (CREW) knew about Foley’s emails, and had not published them (but had brought them to the attention of the FBI) pending the resolution House investigation. The article claims that they published the emails on their website only after ABC News broke the story.

CREW describes itself as “a non-profit, progressive legal watchdog group”, and their blogroll contains links to blogs ranging from the hard to the completely loony left…which makes their circumspection in the matter seem a little odd. There’s no clear indication as to when they learned of the emails or how long they’ve been sitting on them — nor when they asked the House ethics committee for an investigation (the implication is that they only made the request today, after the matter became public).

“I question the timing,” as they say. Not that it excuses Foley’s actions…if the emails are authentic, it shows Foley was preying on an underage page. But if this “progressive” organization knew about this for some time and waited until a politically opportune moment to act on it, what does that say about their own ethics?

Atlas V For Tourists

Hmm…

Looks like the 8-person capsule is a cross between Apollo (squat capsule) and Mercury (strap-on de-orbit module) — though the conical portion appears to have steeper sides than Apollo. No escape tower. Potentially recoverable docking adapter.

The launch image makes the stack vaguely resemble this rocket, though.

Stick’s Daddy

It seems the Stick/CLV/Ares I was not the first incarnation of a Shuttle SRB-derived launch vehicle:

Candidate boosters were the Titan T-34D, a hybrid Atlas Centaur G, and the NASA SRB-X/Centaur. The SRB-X was only in the conceptual stage, and it appeared that readiness for the required first launch by 1988 was not possible. Modifications to the two other candidates are also necessary, however, to meet the GEO capabilities, while the SRB-X is designed to make maximum use of existing launch preparation facilities used for the Shuttle.

The idea just keeps coming back around…like a bad penny.

Of course, the same could be said about the CaLV/Ares-V, in that there are about as many “Shuttle-derived heavy lift launch vehicle” concepts as there are tiles on an orbiter.

Well…That Was Unexpected…

Three weeks ago Lockheed Martin was being slagged as a poor choice for Orion, incompetent, a dinosaur, the enemy of alt.space, etc. And now? LM is suddenly…alt.space, itself:

Initially, and due to the huge amount of money involved, the companies will announce they are to focus on exploring the technical requirements for the human-rated launch services needed to transport commercial crew and cargo to expandable orbital space complexes. Bigelow and Lockheed Martin will examine the production and supply of Atlas rockets and comprehensive data describing flight safety and performance. Potential business models and business plans will also be discussed.

The companies expect an Atlas V 401 single-core configuration to be the most likely launch vehicle. Lockheed Martin literature and graphics, obtained by NASASpaceFlight.com, portray a wide, 8-person capsule atop a combined abort and orbital maneuvering system in an Atlas V 401 stack. The passenger vehicle itself could change to a different design.

Up to 16 manned Atlas V 401s per year are anticipated. Current Atlas V family launch rates are closer to two to four launches per year. If realized, this increased launch volume could drastically decrease the Atlas V per-launch costs, and significantly change the US launch market.

Wow. How sweet is that?

The reason for the NASA ESAS man-rating concerns was due to the 25mT CEV mass requirement, which ESAS maintained could not safely even be met by the massive Atlas V Heavy variant. According to a Lockheed Martin paper unveiled this week at the Space 2006 conference, the basic Atlas V 401 can meet FAA and NASA man-rating requirements with little modification with a much smaller capsule mass of 20,000 lbs.

Considering what we had to do to fit six people in a CEV capsule roughly more than twice as heavy, I can only imagine that this 8-person capsule would be significantly simpler, less capable, shorter duration, and, ahh, cozier than what NASA wanted for CEV. Which is not really surprising, considering CEV is intended for lunar flights as well as LEO…if you don’t need a toilet or a galley on board and don’t have to carry consumables for more than a couple of days (among other possible differences) it could lighten things up a bit.

But 20,000lbs? The Apollo CSM weighed in at around 66,000lbs. On the other hand, Gemini weighed around 8500lbs, and had a mission more analogous to this Bigelow taxi spacecraft. It’s a sporty goal, but not out of the realm of the possible…especially if the crew size turns out to be less than 8.

ADDENDUM: Rand Simberg liveblogged the announcement from the AIAA Space 2006 conference.
