“This Week In Space” – September 5, 2010

September 5, 2010

The latest edition of “This Week In Space” is out!

Hello and Welcome.  This week we have everything from NASA creating vomit in a lab to fire and smoke, and let’s cut right to those flames you want to see…

ATK DM-2 Motor Test. Source: NASAFIRE and smoke blasted out of the  most powerful solid rocket motor designed for flight – a 5 segment solid rocket booster.  This was a NASA and ATK test in Promontory Utah.  It was a 75 million dollar test of a rocket that President Obama wants cancelled.  This five segment motor was built to power the Ares I rocket meant to fly crews to space.   This one blasted out a 600 foot long flame that was 5600 degrees and can generate up to 3.6 million pounds of thrust.

We LOVE an excuse to show catchy video anytime here at TWIS – and NASA just gave us two good reasons.  The agency selected two companies for experimental space vehicle test flights…Armadillo Aerospace and Masten Space Systems and awarded them a total of about half a million dollars.  The awards will be used by the two companies to test their systems near the edge of space.  That’s considered to be the area between 65 thousand and 350 thousand feet.  The CRuSR awards will fund two flights this fall and one this winter of Armadillo’s Super-Mod vehicle from Spaceport America in New Mexico. The first two flights will be to an altitude of approximately nine miles and the third to approximately 25 miles.  A Masten Space Systems’ vehicle will make four flights this  winter from the Mojave Spaceport in California. Two flights will reach an altitude of approximately three miles and two others will be to approximately 18 miles.

All good things must come to an end – and that was the case Monday for NASA’s ICESat spacecraft, which fell to Earth in a controlled re-entry over the Barents Sea.  The spacecraft weighed about a ton, and NASA expected about 200 pounds of debris to survive the fiery plunge to the surface.  Launched back in 2003, ICESat was an Earth Observing satellite designed to measure the thickness of both land and sea ice – as well as vegetation, clouds and atmospheric aerosols.  Its laser instrument stopped working last year, and controllers fired on-board thrusters over the summer to adjust its orbit and bring it down in a safe and controlled fashion.  And here’s a cool twist – NASA farmed out the planning work on the final maneuvers to students at the University of Colorado Boulder.  It was a great project for them, and it saved some tax dollars too.   ICESat 2 is on the books to launch in 2015.

As long as we are de-orbiting things…Tuesday was trash day up on the International Space Station.  In space it is a little more complicated than pushing the big green bin out to the curb.  As you know, the station gets regular shipment of supplies via unmanned Russian Progress vehicles.  Once the station crew members unpack all the cargo, they start packing trash back in.  When it is full, the Progress undocks and Russian ground controllers eventually deorbit it and it burns up over the Pacific Ocean.  The station crew waved bye-bye to Progress 38 in time to start preps for the arrival of Progress 39, set to launch from Kazakstan on September 8 and dock at the station two days later.  Also on the ISS, astronauts were keeping an eye on hurricane Earl from 218 miles up…talk about a birds-eye view.  And one more piece of station news before we move on.  NASA crew assignments for Expedition 34 and 35.  The headline:  in March 2013, Canadian astronaut Chris Hadfield will assume command of the ISS – making him the first Canadian commander.  Way to go, Chris, ‘eh?

The NASA family bid farewell this week to astronaut Bill Lenoir, who died at age 71 of head injuries sustained in bicycle accident.  Lenoir was a “scientist-astronaut” selected in 1967, and he waited a full 15 years to make his one and only flight.  In the shuttle program, he is a man of many firsts.  He flew on the first “operational” shuttle mission, STS-5.  The previous four were considered test flights.  He and Joseph Allen were the first mission specialists to fly on the shuttle.  He was the first flight engineer to assist the Commander and pilot during a launch on the flight deck.  He switched seats with Allen for the return home, and so he was the first astronaut to ride back to earth on the middeck.  He and his crewmates deployed the first commercial shuttle payloads into orbit – two communications satellites.  And he and Allen were supposed to conduct the first spacewalks from the shuttle – but space sickness and suit malfunctions scuttled that plan.  Lenoir went on serve three years as Associate Administrator for Space Flight.

Check out this super-cool visualization of the solar system that shows the location of asteroids over time as we earthlings discovered them.  Here’s what our situational awareness was in the year 1980.  But let’s skip ahead a bit.  Discoveries really took off  around the year 2000 or so.  The ones in red are so-called Earth crossing asteroids – need to keep a particularly close eye on those.  It’s like Yogi Berra said – you can see a lot by just observing.  Another interesting asteroid tidbit this week.  There’s been a lot of buzz in recent months about a possible manned mission to an asteroid, perhaps sometime in the 2020’s.  Well, opportunities to do that may not be as plentiful as you might think.  We can’t  go to any just any old asteroid – we would need to choose one that’s got to be zipping through space at the right speed, its got to be spinning just right, viewable by ground-based telescopes, and reachable using a heavy-lift rocket that will presumably be developed between now and then.  When you put all that up on the scale, you know how many suitable asteroid candidates there are for a manned mission in the 2020’s? According to the NASA Near Earth Object Office:  Two.  Of course, we may discover others.  Which would be great.  It’s always nice to have options.

Here’s a new view of a mysterious Martian crater, compliments of the European Space Agency’s Mars Express spacecraft.  It’s called “Orcus Patera,” and scientists are not sure how it formed.  A leading theory:  it’s an impact crater from a small object that hit at a shallow angle.

From Mars to Mercury.  NASA’s MESSENGER spacecraft  has been executing flybys of our solar system’s inner-most planet for the past couple of years, and is preparing to pull into orbit around Mercury next March for a year-long science mission.  Here’s a MESSENGER image looking back at Earth snapped about 3 months ago, during its closest approach to the Sun.  Check out the moon.  Is that cool or what?

If you want to keep on top of missions like MESSENGER, NASA has a new iPad out called NASA App HD, free at the App Store.  Among other new features, you can stream NASA TV live…and view images like that one we just showed you from MESSENGER in high resolution. Also, NASA has started putting more of its image archives up on Flickr.   You’ll find a lot of new imagery up there, but also a fair amount of historical material too.  Point your browser to our web site for a link.  That’s spaceflightnow.com/twis

Here’s a story that really stinks.  NASA is creating vomit in a lab.  Really.  So why does the space program need vomit?  Here’s what researcher Nikki Williams at the Johnson Space Center  told roving reporter and astronaut Mike Massimino.

We need to put all the trash you’d have on a space mission on that trash bag.  That includes potentially vomit, diapers.  It sounds like a baby place.

So it’s for a new trash bag test. There is a vomit recipe from medical research that NASA based their formula on.  Fake vomit …eg…kinda makes me want to …(gags) nevermind…I’ll be ok.  If you want to see more of NASA’s vomit research – come on you know you want to, head to our page spaceflightnow.com/twis.
Time for us wrap this up…I’m feeling a little sick.  Don’t need any Odorama “scratch and sniffs” to go along with that story.   Thanks for watching.  If you like us, please consider tossing us a few bucks via Paypal at spaceflightnow.com/twis.  Send us an email twis@spacelfightnow.com,  tweet us @thisweekinspace.

'This Week In Space' May 22, 2010

May 23, 2010

The lastest edition of “This Week In Space” is now out!  Give us a watch…

[youtubevid id=”DLtU46K_3aM”]

Hello, and welcome…
We have a scoop for you this week – an exclusive interview with SpaceX founder Elon Musk – we’ll ask him how things are going as he and his team prep for that high stakes first flight of the Falcon 9 rocket…And we’ll also share with you David Letterman’s reaction to seeing his first shuttle launch…that’s coming up shortly…But first some other space news – and this week in honor of the Falcon 9 countdown and Dave’s first launch – we are doing it top ten list style…

Number 10

The Mars rover "Spirit." Source: NASA/JPL

Comes from the fourth rock from the sun.  (Miles mutters to himself and counts on his fingers).  Mars!  Yeah, Mars.  On March 20, the rover Opportunity overtook the Viking-1 Lander and is now holds the surface longevity record for NASA probes on Mars.  Opportunity is now six years, 116 days and counting into a 3 month mission.    But if you are listening Oppy – don’t rest on your laurels.  Your sibling  Spirit on the other side of the planet  is in winter hibernation mode, and if she manages to wake up come Spring, she will grab the record.  Spirit landed on Mars about three weeks before Opportunity back in 2004.  And as long as we are on Mars – the team at the Jet Propulsion Laboratory commanded the the Mars Odyssey spacecraft to make  a final listen for life signs from the Phoenix Mars Lander this week.  Phoenix landed in the Northern polar region back in 2008, and operated successfully for about 6 months until the cold and dark of the Martian winter set in and craft went silent.  Mission managers were pretty sure that the lander would not survive the winter, but figured it wouldn’t hurt to see if they might be able to reestablish communication.  Looks like “no dice” though.  Rest in Peace, Phoenix.

Number 9

An update on a manned mission to Mars that is launching next month – had ya there for a minute didn’t I? Actually this is an ersatz trip to Mars that will never get off the ground.  I am talking about the Mars 500 SIMULATED mission to the red planet. Liftoff – well actually lock down – is set for early June.  Six crew members – two Europeans, one Chinese, and three Russians will spend 520 days locked inside a spacecraft mock-up at the Institute of Biomedical Problems in Moscow.  Mission controllers are doing their best to make this mission as close to the real thing as possible.  They’ll have to take all the food they’ll need with them from day one – no ordering in pizza a la Biosphere 2.  Communication is limited to email, – and it will be intermittent – just as it would on a really interplanetary voyage, and it will include a delay of as much as 40 minutes.   ESA has picked their two crew members.  Diego Urbina, who has Italian-Colombian nationality, and Frenchman Romain Charles.  The rest of the crew will be announced later this month.

Number 8

Oil’s not so well in the Gulf of Mexico – and NASA is pitching in to help. The space agency flew its King Air  research aircraft over the Gulf of Mexico this week in an effort to help monitor the size and thickness of the BP oil spill…Researchers wondering how the oil might impact sea life.   The Langley Based King Air 200 was outfitted with instruments normally used to study clouds and aerosols in the atmosphere – which researchers hope can help them learn more about spills. NASA satellites have also been trained on the oil slick since the drilling rig exploded in April. Crew members aboard the ISS have a unique vantage point to keep an eye on the growing environmental crisis.  Cosmonaut Oleg Kotov has been watching the oil spread.
