On International Women’s Day, Google Celebrates NASA Pioneer Mae Jemison

Posted by in categories: bioengineering, biotech/medical, space

Never be limited by other people’s limited imaginations… If you adopt their attitudes, then the possibility won’t exist because you’ll have already shut it out… You can hear other people’s wisdom, but you’ve got to re-evaluate the world for yourself.

As a physician, Peace Corps volunteer, entrepreneur, teacher, dancer, and astronaut, Jemison has certainly lived her life in protest of people’s limited imaginations. Born in 1956, Jemison’s interest in STEM rooted early, and she enrolled at Stanford University when she was only 16. She majored in degrees in both chemical engineering and Afro-American studies, and she went on to receive an M.D. just four years later.

Jemison worked as a medical practitioner and served for two-and-a-half years in the Peace Corps as a medical officer. When she returned to the United States in 1985, she did something incredibly difficult: She pivoted her career entirely to pursue her childhood dream of becoming an astronaut. Jemison applied to the NASA astronaut training program, was selected from a field of 2,000 individuals, and in 1992, became the first African-American woman to go to space.

What to do with the lignin?

Posted by in categories: bioengineering, biological, genetics, space, sustainability

Learning to deal with lignin is important for recycling and space settlements. Unused biomass on space settlements and long-term voyages is something that just can’t be tolerated. The same problem exists in dealing with plant waste on earth. A new process helps convert it into a precursor for polyester, which can be used for all kinds of other materials.


Plant cells are composed of three main substances: cellulose, hemicellulose, and lignin. According to Yining Zeng, Michael E. Himmel, and Shi-You Ding in Biotechnology for Biofuels, the composition amounts to “40 to 50% of cellulose, 15 to 25% hemicelluloses, 20 to 25% lignin, and 5 to 10% other components.[1]” For the most part, the only truly useful part is the cellulose and the hemicellulose. The lignin is usually just thrown away. The most common use is fuel for heating units. That’s right. They just burn it.

Goals for collecting and studying samples from Mars

Posted by in categories: engineering, space

A paper, “The potential science and engineering value of samples delivered to Earth by Mars sample return,” authored by 71 scientists is available. According to the summary at Science Daily.


Returning samples from the surface of Mars has been a high-priority goal of the international Mars exploration community for many years. Although randomly collected samples would be potentially interesting, they would not be sufficient to answer the big questions that have motivated Mars exploration for decades. A new paper published in Meteoritics & Planetary Science describes the results of a major collaboration among 71 scientists from throughout the international science community to define specific scientific objectives for a Mars Sample Return campaign, to describe the critical measurements that would need to be done on returned samples to address the objectives, and to identify the kinds of samples that would be most likely to carry the key information.

2 female NASA astronauts and a Canadian flight controller will conduct the first-ever all-woman space walk

Posted by in category: space

Almost 35 years after Svetlana Savitskaya became the first woman to walk in space, history will once again be made.


Since 1998, there have been 213 spacewalks at the International Space Station. In March, an all-female spacewalk is happening aboard the ISS.

Despite being the very first candidate planet discovered by our Kepler Mission, Kepler-1658b had a rocky road to confirmation. Ten years later, scientists have now confirmed that it is, in fact, a planet. It whips around its star every 3.85 days. Details: https://go.nasa.gov/2TDlaIl
