ET-138 rolls out at the Michoud Assemby Facility. Source: NASA

Hello and Welcome. We begin with a big orange caboose – if you will. The last space shuttle external fuel tank on the manifest made its way out of the barn at  Michoud Assembly Facility in New Orleans. The tank  is known affectionately as ET-138…but you can can call her “E” if you like. Tank builder Lockheed Martin pulled out all the stops for this one – hundreds of workers were on hand while a brass band played. The tank will ride on its custom barge to the Kennedy Space Center where it will be mated with Endeavour, now slated to fly the final shuttle mission N-E-T – or no earlier than – February 26th, 2011. Now there is one more tank that will be shipped from Michoud – it will be used by Atlantis should the Endeavour crew get in a jam – and need a lift home. And this is where I get to put in my plug for flying that tank – with Atlantis – one more time. Why not? And this is also where I get to nag you: if you have not seen a shuttle ride the fire to orbit – you are assigned to be at one of the last launches. No excuses. There will be a test later.

Tanks for the memories – I guess – prime shuttle contractor United Space Alliance announced its largest layoff to date –  15 percent of its workforce.  Most of those employees are in Florida – since that is where most of their employees live.  Somewhere between 800 to a thousand wrench turners and pad rats will be getting pink slips.   Another 400 or so will be sacked from other USA operations. More cuts, are expected of course as the program winds down.

And that would explain the turnout at recent job fairs at KSC – somewhere between 2 and three thousand shuttlers showed up to press the flesh and hand deliver some resumes. About 60 public and private sector employers showed up. Can you guess which company had the most popular booth? Why that would be a certain California based launch company called SpaceX.  Better SpaceX than ex-space I suppose.

If any of those jobless USAers are space history buffs – and I know there are more than a few you – you may want to consider this job: official NASA historian. apply at USAjobs.gov by the 13th. Also in the comings and goings department – NASA’s Wayne Hale is hanging up his headset but we hope not his keyboard – the veteran flight director, shuttle program manager – and eloquent blogger says its a personal decision. I sure hope he keeps sharing his pearls of wisdom with us. And the Hubble repairman just added another line to his long resume – John Grunsfeld is now a research professor at Johns Hopkins. he will keep his gig down the road as the number two man at the space telescope science institute – which is Hubble Science Central. Hey if he can’t multi task – who can?

Hello and welcome – and happy Yuri’s night – hard to believe it has now been 49 years since the first human being left the planet – and 29 years since the first shuttle flew – we’ll check in with one of the founders of the global Yuri’s night celebration – in a little while – see what is in store this year –

But first – let’s talk about the 131st space shuttle mission – currently “in work” as they say in the space business. I must admit – I am pretty lucky to have witnessed a lot of shuttle launches – and each of them is beautiful in their own special way – like a snowflake I suppose…but this one stands out – for one thing – we got a great view of Discovery’s destination – the international space station – as it flew overhead in the predawn darkness shortly before launch…then came the launch itself,

Those of us at the cape were able to see Discovery with eyes only – for a full seven and a half minutes – no one can remember anything like that – and then after Discovery was out of view and safely in space – were were left with this spectacular scene as the sun rose…remnants of the shuttle plume lit up like a pastel painting…

Discovery commander Alan Poindexter had to dock his craft at the station without the benefit of a radar system that failed. It is the same device that allows the orbiter to send out streaming video (or what we used to call TV)…and so that meant they had to record the heat shield inspection – and then send it down to earth using the station’s system.

The joint crews successfully attached the space equivalent of a PODS moving crate to the station – the Leonardo Multipurpose Logistics Module – in it – about 17 thousand pounds of gear and supplies – including some new crew sleep quarters…a fancy exercise machine that will give researchers a better idea about how physically fit the station-keepers are…and a device that ads cameras, spectrometers and other sensors to better observe the earth as it passes below the station.

They do see some cool things up there – look at this shot from crew member Soichi Noguchi of the Aurora Boraealis – or Northern Lights – he tweeted that one down.

Three spacewalks are planned for the 13 day mission.

Late as this is in the shuttle program – there is still room for some firsts as well as lasts – there are four women on the  combined shuttle station crews – a space record. And no – none of them stopped and asked for directions.

Space for the rest of us is got just a little closer this past week. Over the high desert of California – in the rarefied air where the X-1, X-15 and the space shuttle first tested their wings – a new spaceship took flight for the first time. I am talking about the Virgin VSS Enterprise – bolted beneath its carrying aircraft – the VMS Eve – formerly known as White Knight 2. The test flight lasted just less than 3 hours – they reached 45 thousand feet – and we are told it went well. Eve/Enterprise designer Burt Rutan called it “a momentous day for the Scaled and Virgin Teams.” Ahead – independent glide tests and then powered flight this year and next. Once the team is happy – revenue service to space will begin… Eve will take Enterprise to 50 thousand feet – where they will part company – the rocket motor will fire –  Enterprise will make a beeline for the dark sky – carrying a half dozen paying passengers into a new era.

Source: NASA/JPL-Caltech/University of ArizonaIt is springtime in the northern hemisphere of Mars – and while NASA’s lander called Phoenix has not survived the long dry ice encrusted winter – there are signs of – activity, though not life – elsewhere on the Red Planet.  Check out this image captured by the Mars Reconnaissance Orbiter. The dark spots are patches of basaltic sand that is carried to the surface as the temperature warms and the dry ice sublimates – meaning goes straight from a solid to a gas – skipping the liquid stage (it’s just a phase). Notice how they all fan out in the same direction – proof they formed at the same time – when the wind speed and direction were identical. Basalt fans – a sublime sign of warmer days ahead on Mars – sorta like our Washington cherry blossoms here in the U.S.

It will be the fall of 2011 before the Mars Science Laboratory makes its way to the Red Planet. The ambitious rover mission was supposed to be there by now, but the launch was delayed after a host of technical and money woes (the two tend to go hand in hand – see: Constellation). In any case, the folks at The Jet Propulsion Lab in California – are glad they got an extra 26 months – because this mission is the most complex ever.

Source:  Hubble Space TelescopeAnd while it may be a long time before humans ever get to Mars – you can simulate the long journey now – if you are so inclined.  The Russian and European space programs have teamed up for an endurance experiment that seems like the premise for a bad reality TV show – survivor meets big brother I suppose…these are some of the applicants for Mars 500 – a 520 day trip to nowhere that will try to create the rigors and challenges of a piloted mission to the Red Planet. The ersatz spacecraft sits at the Russian Institute of Biomedical Problems. Three Russians, two Europeans and One Chinese will be hermetically sealed inside the steel container in May. They will live in 550 cubic meters – will only eat from food stored inside – and will communicate with the outside world either by deliberately ratty internet – or with a 20 minute one way delay once they reach simulated Mars. The goal: to better understand the psychological and physiological rigors of such a, long, isolated mission.   The big question: whether to select a rainbow coalition Star Trek like crew – or a bunch of GI-Joe’s – who think act and look alike. So should we take a pool to on whether they will make it the full 520 days? I sure hope there is a webcam…appointment TV for space cadets for sure.  Though the team final team has not been selected yet, candidate Arch’hanmael Galliard, of France, is feeling strong about his chances.

“I think that I will be accustomed rapidly to this environment.  I thought at the beginning this environment could be smaller.   No, I think everything could be done here  – experiments, living, doing sports,  there is many things that we can do, I think, during this period, we will see with time, if it is really possible or not, but I think that we can do it.”

The Mars 500 crew will sure have plenty of time to refine their video game playing prowess. And a now ESA is out with a new study that suggests gaming can enhance collaboration among scientists and engineers – and can be a good education and public outreach tool. The study suggests ESA strike deals with some game developers to create titles that teach – how about Grand Theft Spacecraft? I suppose not…

Two million parts – all of them form the low bidder – as Wally Schirra  once famously quipped – if you put those parts together just right – you’ve got yourself a space shuttle – the problem is – just about every single one of them has to be working perfectly before a shuttle ever clears the tower.  But exceptions can be made….and that is what the shuttle launch team is doing for this next launch. With Discovery sitting on the launch pad for its penultimate flight – a helium valve  failed. The helium is used to make sure there is pressure in the fuel lines that feed the Orbital Maneuvering System engines – which handle the big course changes in orbit. Fixing the valve means a roll back to the the hangar – and a big delay. So the shuttle team will try to verify that some regulators downstream of the valve are working just fine. If so, it means they will have confidence they have only lost one layer of redundancy – and thus give Discovery its launching papers.

this one is no sled though – it is a cosmic blossom in a cluster of stars in the Berkeley 59 – which sounds a little like a group of sixties anti war radicals…anyway…the blue dots are the stars…and they are formed by the orange dust cloud in the middle – and the green – those are polycyclic aromatic hydrocarbons – of course…you can find those on earth in barbecue pits…for some reason I am hungry…WISE is also hunting for asteroids – and it has found more than a dozen that are near to earth – and we didn’t even know we were there. You’d be WISE to listen to this story – Chicken Littles.

The WISE guy has hit some pay celestial pay dirt.

NASA’s Wide-field Infrared Survey Explorer, launched in December – took this shot of a near earth asteroid on January 12th. Designated 2010 AB78 – (comets have much more fun names…) this asteroid is 158 million kilometers (98 million miles) from Earth. Diameter is one kilometer or 6 tenths of a mile. Scientists say this space rock is not on a path to collide with earth in the foreseeable future.

But an expert panel has just concluded we are not being so wise about conducting a survey of big near earth asteroids that could clonk us and wreak havoc. The National Research Council says the goal to find 90% of the earth threatening asteroids 460 feet/ 140 meters or larger 2020 will not be met – for lack of funding. Scientists say an asteroid as small as a hundred feet – or 30 meters across – could take out a city. If you don’t think this is money well spent – go ask a dinosaur what he or she thinks.
