Exoplanet Found Orbiting Double Stars

For those of you who are Star Wars fanatics, we have all witnessed the scene from Episode IV of Tatooine's double suns setting in the desert planet's distance.

There's also another truism amongst science fiction devotees that has been borne out by our history that today's science fiction is tomorrow's science fact.

Was intrigued to find out about the accidental discovery by the planet hunting Kepler telescope of one that was found in the Kepler-16 star system 200 light years away from planet Earth orbiting two stars smaller than our own   

"This discovery confirms a new class of planetary systems that could harbor life," Kepler Principal Investigator William Borucki, of NASA's Ames Research Center in Moffett Field, Calif., said. "Given that most stars in our galaxy are part of a binary system, this means the opportunities for life are much broader than if planets form only around single stars. This milestone discovery confirms a theory that scientists have had for decades but could not prove until now."

The planet does so in 229 Earth days, and we probably aren't going to find Luke Skywalker and Artoo Detoo on it because it is a cold Saturn style and sized gas and rock ball that lies outside the binary stars habitable zone   The Kepler project scientists are checking to see if the Kepler-16 planet has habitable moons similar to Pandora in the Avatar movie.   

At the rate they are finding exoplanets over the last several years, it's past time to get busy finding a way to get us to them in an expeditious manner. ..

China Building A 'Heavenly' Space Station

As the US space program ended thirty years of shuttle flights with the successful completion of the STS-135 mission and is moving away from low earth orbit operations to other goals, the Chinese are going full speed ahead with preparations for the launch of the first module of their Tiangong space station.


Tiangong means 'Heavenly Palace', and the first steps toward building it were undertaken during the three man Shenzhou-7 mission in September 2008 when Zhai Zhigang became the first Chinese taikonaut to conduct a spacewalk. 

The first TG-1 module for it is being prepped for a September launch. After it achieves earth orbit an unmanned Shenzhou-8 mission will be launched to commence several weeks of testing of the rendezvous and docking capabilities of the TG-1 module.  

If those tests of the Tiangong-1 module are successful, then manned Shenzhou-9 and Shenzhou-10 missions will be sent aloft next year.   The station will be comprised of the core TG-1 module with two experiment modules and docking ports for cargo craft.   The first of the two experiment laboratory modules is planned for a 2016 launch with the completion date for the 60 ton station set for 2020.

In November China will also take its first steps toward its goal of a manned mission to Mars by launching from Baikonur Cosmodrome in Kazakhstan in conjunction with the Russian space program the YG-1 Yingho Mars probe.

The YG-1 was scheduled to be launched in October 2009 but preparation delays with the Russian probe pushed back the launch timetable.  After it takes the year in transit to get to the vicinity of the Red Planet the two probes will separate and orbit the planet independently.

China is also interested in participating in the International Space Station.  The docking rings on the Tiangong 1 are supposed to be compatible with the ISS ones, but I haven't been able to confirm that for certain yet. 

The 60 ton Tiangong 1 is scheduled for completion by 2020, but they'll need to have the first critical step of that process, the launch and successful insertion into orbit of the TG-1 module be executed  successfully in a few weeks .

The Space Shuttle Program Made Black History As Well

The Space Shuttle program concluded with Atlantis touching down at the Kennedy Space Center earlier this morning in Florida at 5:56 AM EDT to cap a successful STS-135 mission and close out its 30 year run.

During that time 355 individuals from 16 countries flew 852 times on the five shuttles, traveled over 542 million miles, over 20,000 earth orbits and a lot of historical firsts.

We African Americans also played major roles in shaping this part of America's spacefaring history.

In addition to the people who worked in the ground support roles, Star Trek's Nichelle Nichols worked for NASA, helped recruit some of the first class of African American astronauts and lead the charge to get more African American kids interested in science, engineering and math careers.  

There were 20 African American astronauts, and out of the 355 individuals that flew on the various shuttles, 14 of those African American astronauts got to fly into space. We witnessed much African American history being made as the result of those shuttle flights.      


During the launch of the STS-8 mission aboard Challenger the first African American in space, Dr. Guion Bluford on August 30, 1983.  It was the first of his four trips into space, with launches aboard STS-8, STS-61-A in October-November 1985, STS-39 in April-May 1991 and STS-53 in December 1992. 

Bluford however wasn't the first African descended person to go into space. That honor went to Cuba's Arnoldo Tamayo Mendez on September 18, 1980.

Dr. Mae C. Jemison became the first African American woman in space as part of the STS-47 crew on September 12, 1992 aboard Endeavour

Frederick D. Gregory became the first African American to command a shuttle flight when Discovery blasted off on November 23, 1989 on the STS-33 mission.  He was also the first to pilot a shuttle when Challenger took off during the STS 51-B mission on April 29, 1985.

Gregory was the deputy administrator of NASA from 2002-2005 and became interim director of NASA covering the period when Sean O'Keefe resigned on February 20, 2005 to Michael Griffin's April 14, 2005 swearing in.


Gen. Charles Bolden was the second African-American astronaut to pilot a shuttle and the first to command a shuttle mission.  He piloted the Columbia during the January 1986 STS-61C mission and Discovery during the STS-31 mission in April 1990.  He was the commander of the STS-45 mission aboard Atlantis from March 24-April 2, 1992 and STS-60 mission aboard Discovery in February 1994 before he became the current NASA administrator on July 17, 2009.  

The first shuttle mission to launch two African Americans simultaneously into space was STS-116 on December 9, 2006.  Aboard Discovery was Robert Curbeam, Jr on his third fight and Joan Higginbotham on her maiden trip into space. 

That Black history milestone was repeated on November 16, 2009 when STS-129 launched with Dr. Robert Satcher and Leland Melvin aboard.

There have been five African-American astronauts who have performed spacewalks in the history of the shuttle program.  The first was by Bernard Harris when he emerged from Discovery on February 9, 1995 during STS-63 to perform his EVA that lasted 4 hours and 39 minutes. 

Astronaut Winston Scott would perform 3 total spacewalks during his STS-72 and STS-87 missions.   Scott's first spacewalk was a 6 hour and 54 minute one on January 17, 1996 and he performed two during the STS 87 mission.  The first was a 7 hour and 43 minute EVA on November 25, 1997.   The December 3 EVA was 4 hours and 59 minutes in duration. 

Robert Satcher would perform two EVA's during the STS-129 mission on November 19 (6 hours and 37 minutes) and November 23, 2009 (5 hours 42 minutes)

But it was Robert Curbeam, Jr. who would become the hardest working man in the spacewalking business, totaling 7 total EVA's across two of his three shuttle missions..

Curbeam performed the first three during his second mission aboard STS-98.   The first on February 10, 2001 was 7 hours and 34 minutes in duration.   The second EVA on February 12, 2001 was 6 hours and 50 minutes long and the third on February 14 lasted 5 hours and 25 minutes.    

Curbeam was even busier during the December 2006 STS-116 mission.  The first EVA was a 6 hour 26 minute one on December 12, followed up by a 5 hour one on December 14, a 7 hour and 31 minute one on December 16 and a 6 hour and 38 minute EVA on December 18 to make up number seven. .   . 

STS-133 astronaut B. Alvin Drew's March 2, 2011 6 hour and 37 minute EVA during Discovery's last mission has the distinction being the last one performed by an African American astronaut   Drew also holds the distinction of being the 200th human to walk in space when he did so for 6 hours and 14 minutes on February 28, 2011.

African-American women aren't left out of this space shuttle program history making either.  As I mentioned earlier, Mae Jemison was the first of three launched into space in 1992 with her historic flight being followed by a long interval until Stephanie Wilson and Joan Higginbotham were launched a few months apart in July and December 2006.  

And for you sorority sisters keeping score, Dr. Mae Jemison is an AKA while Dr. Joan Higginbotham is a member of Delta Sigma Theta.   For you fellas wanting to know what astronaut belongs to your frat, here it is.   Winston Scott is a member of Alpha Phi Alpha,  Bernard Harris is a member of Kappa Alpha Psi,  and Frederick Gregory and the late Ron McNair are members of Omega Psi Phi. 

But back to the spacefaring ladies for a minute. 

Stephanie Wilson would not only become the second African American woman into space when she was launched on July 4, 2006 aboard Discovery as part of the STS-121 crew, she would go into space two more times as part of the STS-120 mission on October 23, 2007 and STS-131 on April 5, 2010.  

Wilson was also part of the historic April 9, 2010 day when four women, the most ever in space at one time, met on board the International Space Station.   STS-131 was also notable because three women were launched and part of a shuttle flight crew.  .

That history also includes the people we tragically lost.   Dr. Ron McNair flew previously on STS-41-B on February 3, 1984 and was part of the ill fated Challenger crew that perished in January 28, 1986 shortly after liftoff.    

Col Michael P. Anderson flew previously on STS-89 but died when the Columbia broke up over eastern Texas on February 1, 2003 during reentry on the STS-107 mission. 

We'll also remember our first ever African American astronaut, US Air Force Col. Robert H. Lawrence, Jr.   Had he lived, it's possible he could have become a shuttle program astronaut.

He was selected in June 1967 to become part of the Air Force's Manned Orbiting Laboratory program.  Unfortunately he was killed in a December 8, 1967 training accident at Edwards Air Force Base in California..

Because of the increasing technical capabilities of spy satellites, the MOL program became obsolete and was canceled in 1969.   Seven of its 14 selected astronauts were under age 35 and given the option to be transferred to NASA.    Those seven accepted the transfer and every one of those former MOL astronauts flew shuttle missions. 

So it's not a stretch to say that had he lived, Lawrence could have had the distinction of becoming the nation's first African-American astronaut launched into space since he was only 32 at the time of his death.   

Discussing our first African American astronaut is a nice segue into discussing the shuttle program's African American astronauts that didn't get an opportunity to be part of a shuttle mission.  


Livingston Holder was a mission payload specialist who was scheduled for an STS mission aboard the Challenger until it was destroyed in 1986 and that mission was subsequently canceled during the 32 month hiatus to investigate the tragedy. 

Astronauts Michael E. Belt, Dr. Yvonne Cagle (astronaut Class of 1996) and Jeannette J. Epps (selected as an astronaut in June 2009) didn't get to fly any shuttle missions.

It's ironic that the NASA Space Shuttle program went out the way the earlier Mercury, Gemini, Apollo and Skylab programs started and ended with predominately white crews since there were no African American astronauts selected for the final STS-134 and STS-135 missions.  

The contributions of African Americans to the success of the shuttle program, in advancing our scientific knowledge, our spacefaring legacy and being integral parts of it are undeniable facts.

We know that if America ignores the parsimonious  neo-Luddites in the Tea Klux Klan and sees the wisdom of remaining a spacefaring nation, there will be African Americans ready and able to make significant contributions toward helping us to keep reaching for the stars and build on the sterling legacy of African descended shuttle astronauts. .

And as we do so, we'll be writing the next chapters of Black history..

Apollo 11 Moon Landing Anniversary

I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project in this period will be more impressive to mankind, or more important in the long-range exploration of space; and none will be so difficult or expensive to accomplish.   President John F. Kennedy,  May 25, 1961 


42 years ago today on July 20, 1969 the United States and NASA fulfilled President Kennedy's goal by landing astronauts Edwin 'Buzz' Aldrin and Neil Armstrong on the moon in the Eagle landing craft while Michael Collins orbited the moon in Columbia.

Armstrong and Aldrin became the first humans to walk on the lunar surface, spent 21 hours and 31 minutes on the Moon, collected 47.5 pounds (21.5 kg) of moon rocks before they blasted off its surface to rejoin Collins and splashdown in the Pacific Ocean on July 24.

But this anniversary of the crowning achievement of the Apollo program is tempered by the bittersweet arrival in a few hours of the space shuttle Atlantis from its final mission to the ISS to cap the Space Shuttle program

So as the space shuttle touches down for the last time at KSC it's causing space junkies like myself to ask what's next for the US space program as we shift our sights away from low earth orbit missions and hand that responsibility to the private sector.

I believe the United States and NASA needs to be doing everything possible to expand our knowledge and technological capabilities in terms of executing space missions to and the eventual colonization of Mars, colonizing the Moon, and solve the challenges and problems of long duration space flights.


It will be necessary to do so not only just to explore our celestial neighborhood but nearby stars and emerging discovered planets as well. 

The United States for its future educational and economic well being definitely needs to continue on the path started by President Kennedy and NASA as a spacefaring nation.   We must be part of any international space exploration efforts or projects like the International Space Station.   

If we want the human race to survive and thrive as a species even with all its flaws we gripe about at times, we must explore the final frontier.
