Blog Post 7: Drake Equation Odds
The Drake Equation is an equation used to determine the odds of communicating with another alien civilization. Created by Frank Drake in the 1961, it was a product of all of the odds of life forming, planets having suitable habitats, and how successful the life was on the planet. The first value was R, or […] Continue reading
Throwing Rockets Into Space Using A Skyhook
One of the biggest issues with rocket launches today is the inefficiency of converting fuel into thrust. Because of this, rocket payloads have to be small compared to the amount of space required for fuel. For instance, the SpaceX Falcon Heavy rocket carries a total weight of fuel of ~411 tonnes (the equivalent weight of […] Continue reading
Asteroids and nucleotides | blog VIII
Just five days ago, researchers identified the last two nucleotide bases in asteroid samples that had previously been unrecognized. Professor and researcher Yasuhiro Oba at Hokkaido University in Japan, alongside a team of scientists, successfully identified the missing cytosine and thymine nucleases. Unlike the other bases, Cyt. and Thy. have very delicate structures, making them […] Continue reading

Bracewell “Messanger” Probes
In 1960, Ronald Bracewell made public his idea of a “Bracewell probe” that was capable of both identifying and exchanging information with intelligent alien civilizations. These probes would be sent toward different star systems and place themselves within a near-circular orbit in a star’s habitable zone. Using solar energy from the star, the probe would […] Continue reading
Acidophiles, pH, and life on Venus | blog VII
The pH scale is used to gauge the acidity and ranges from 0-14, with lower values being more acidic and higher values being more alkali. 7 is the neutral level between the two. Substances like battery or stomach acids have pHs around 0 or 1; water and blood are around 7, with drain cleaner or […] Continue reading
