Horgan passionate about studying Mars’ geology
Briony Horgan grew up in Portland, Oregon, where, enjoying the mountains and volcanoes that surrounded the region, she developed a love of geology. A long-standing interest in space made Horgan realize she wasn’t confined to study rocks simply on Earth. Horgan, now an associate professor of planetary science at Purdue, soon will have an opportunity …
Getting to sleep in space is hard – and not exactly restful for the mind and body
We’ve learned a lot about the effects on the human body of going into space by studying astronauts such as British astronaut Tim Peake, who spent six months aboard the International Space Station during 2015 and 2016. Muscles wither, bones become lighter just as they do during the process of ageing and the cardiovascular system …

Why are scientists trying to manufacture organs in space?
Gravity can be a real downer when you are trying to grow organs. That’s why experiments in space are so valuable. They have revealed a new perspective into biological sciences, including insights into making human tissues. Gravity influences cellular behavior by impacting how protein and genes interact inside the cells, creating tissue that is polarized, …

Preparing for surgeries in space and on Mars
Last year, it was reported that an astronaut in space had developed a potentially life-threatening blood clot in the neck. This was successfully treated with medication by doctors on Earth, avoiding surgery. But given that space agencies and private spaceflight companies have committed to landing humans on Mars in the coming decades, we may not …
This Week in History: December 27-31
DECEMBER 27, 1984: A team of American meteorite hunters finds the meteorite ALH 84001 in the Allan Hills region of Antarctica. This meteorite was found to have come from Mars, and in 1996 a team led by NASA scientist David McKay reported the presence of possible “microfossils” and other evidence of potential biological activity within …
Comet of the Week: Kohoutek 1973f
Perihelion: 1973 December 28.43, q = 0.142 AU This comet’s story starts about two years before its actual discovery when Brian Marsden (at the IAU’s Central Bureau for Astronomical Telegrams) performed some orbital calculations of the long-lost periodic Comet 3D/Biela (a previous “Comet of the Week”). The comet had not been seen since the mid-19th Century …
Special Topic: Putting It All Together
When I first began reading about the solar system as an elementary school student in the mid-1960s, it seemed to be a much simpler place than what we know today. There was the sun, around which orbited nine planets; some of these planets had moons, Jupiter having the most with 12. Between Mars and …
