Thinking About Mars

Thinking About Mars

A lot of Mars activity this week. the Mars Science Laboratory was stacked on its launch vehicle at KSC launch complex 41, and the Mars500 mission "landed."
 
In the mean time, my 4th grade science class has been exploring the basic elements of a sustainable ecosystem. My students decided that the essential components of the ecosystem were energy from the sun, nitrogen in the soil, water, carbon dioxide, and oxygen. With these elements, the ecosystem could support algae and bacteria in a sustainable system. How is this relevant to Mars, you ask? Earth is a special planet where these elements have come together in just the height combination to support life. My students were curious to know if we knew of life anywhere else. I asked them how they could find a planet that might support life. Almost immediately, students suggested that looking for planets the right distance from a sun that had evidence of water, carbon dioxide, oxygen, and nitrogen. What life would you look for? Bacteria and algae! 
 
Mars Science Laboratory and the Curiosity rover will be doing just that. With 10 different experiments on board, Curiosity will explore the are around the Gale crater looking for evidence that Mars has, or could now or in the future, support life. Adjacent to the Gale crater is a mountain formation that appears to have been built in layered deposition in an aquatic environment. 
 
MSL/Curiosity is scheduled for launch on Friday, November 25th. In the coming weeks I will be sharing more about the mission and the work my students are doing. On Wednesday, November 23rd I will be participating in a NASA TweetUp at Kennedy Space Center in conjunction with the launch.

MSL/Curiosity Stacked!


The Mars Science Laboratory (MSL) was moved from NASA Kennedy Space Center's Payload Hazardous Servicing Facility (PHSF) to Space Launch Complex 41 during the early morning of Nov. 3 and hoisted atop the Atlas V rocket. MSL was hoisted atop the payload transporter in the PHSF on Nov. 2 after being integrated into the Atlas V rocket payload fairing.

Curiosity has 10 science instruments to search for evidence about whether Mars has had environments favorable for microbial life, including chemical ingredients for life. The unique rover will use a laser to look inside rocks and release the gasses so that its spectrometer can analyze and send the data back to Earth.

STS-135 NASA TweetUp at NASA HQ


On Thursday, October 13th, I had the privilege of participating in a NASA TweetUp. The TweetUp was held at NASA Headquarters in Washington, DC. This was a gathering of 150 Twitter followers of @NASATweetUp and STS-135 CMDR Chris Ferguson (@Astro_Ferg) and MS1 Sandy Magnus (@Astro_Sandy). Organized by Stephanie Schierholtz (@Schierholz) NASA's Social Media Director, the attendees represented 25 different states, Germany, India, Canada, and Australia.

Stephanie Schierholz opens the TweetUp
Upon entering NASA HQ, Stephanie was there to greet each attendee in person and presented each of us with our official NASA "swag bags" containing an assortment of NASA and STS-135 momentos. My personal favorites: The Space Shuttle 30th Anniversary lapel pin, made from metal that flew on a space shuttle, and the STS-135 mission sticker, and of course my NASATweetUp ID badge. And what would a TweetUp be without the SpaceTweeps? Having time to connect face-to-face is, as the old commercial says, priceless. SpaceTweeps are an interesting and diverse group. Sharing time discussing the space program, swapping shuttle launch stories, sharing about our lives, and speculating on the future of NASA and human space flight were all lively conversations.
It's official! TweetUp badge and NASA HQ.

The TweetUp program included the presentation of the STS-135 Mission Highlights film, featuring a soundtrack by RUSH and a song they had composed to mark the occasion of the launch of STS-1. Ferguson and Magnus shared several anecdotes of their mission and training flow, ranging from the humorous, to serious science and space geekdom. They engaged in a Q&A session, taking questions from the floor at the end of the presentation. The great thing about the event, is that Ferguson and Magnus clearly understood that this was an "inside" audience. The stories they shared were not the same ones we had heard in the various interviews throughout the mission flow. In a couple of cases, they shed more light on stories we had heard. The infamous T-31 sec "been cap" glitch and hold for example. Ferguson commented that, "this wasn't something that had been in the SIMS. It wasn't something that had ever happened." "I was incredulous." The image of the four of them on the flight deck trying to figure out what was going on, much like all of us were doing watching the launch, was  a great one. The image of Ferguson in his CMDR voice, telling everyone on the flight deck to be quiet so he could hear brought images of a family car trip to mind." Ferguson commented further on the hold, "Once I understood what the problem was, I could see it was clear, but [launch control] wouldn't take my word on it."

Magnus shared stories of the difficulties growing up as a young girl with dreams of being an astronaut. "I kept it secret, because I didn't think anyone would understand." Her story affirms how important it is that we provide young girls with positive female role models. Women that they can see as the embodiment of their own dreams. 

I was chosen to ask the final question of the TweetUp. I had several questions for Ferguson and Magnus, ranging from space/STEM geek questions about mission minutiae, to their thoughts and hopes for the next steps with NASA for them personally as well as programatically. The final question had to be something summative and lasting.

MW: "What do you see as the most important skills for children to develop in preparation for their future?"

CF & SM: "Becoming a life-long learner. Adaptability."

Considering more than 60% of our students will take a job that does not yet exist, I think these are great recommendations.

NASATweetup with STS135

Thursday is Tweetup day! I get to visit NASA HQ in Washington DC to join 150 other SpaceTweeps and STS135 Commander Chris Ferguson and Mission Specialist Sandy Magnus. Ferguson and Magnus are two of the four final shuttle astronauts. I've been following them for the better part of a year now, as they went through their training flow, witnessed the launch from Kennedy Space Center on July 8, and met them (briefly) at an autograph signing event at the Intrepid in August. I am looking forward to meeting them and hearing first hand their memories of the mission and their hopes and dreams for our space exploration future. It will also be really fun to meet some of the people I only know through Twitter. It should be a great event.

ISS Flyover Monday, September 19, 2011

Just before dawn on Monday, September 19th, the ISS will flyover the NY metro area. This should be a good pass to watch as it will be nearly overhead and the rising sun should make it very bright.

GRAIL Twin Satellites Successfully Launch for Moon

Video of launch on NASA's YouTube Channel:
http://www.youtube.com/watch?v=1elSL-w1B8g&sns=em

Saturday morning, the twin GRAIL satellites launched aboard a Delta2 rocket from Kennedy Space Center. The satellites will measure the gravity fields of the moon in order to learn more about the interior structure of the moon. They are scheduled for lunar orbit insertion on New Years Eve and New Years Day.
