Being a member of a science team of a planetary mission is like being a starter on a major league baseball team—you’re in the game. That’s how I felt as a member of the MESSENGER mission to Mercury. During the final months of MESSENGER’s time in orbit, before the fuel on the spacecraft was expended and crashed on Mercury’s surface, a decision had to be made—keep the spacecraft in its nominal mapping orbit as long as possible or let the spacecraft altitude drift lower to get as close to the planet as possible.
Long before your laptop computer and the computers that took us to the Moon, there was another type of computer. In the early 20th century, women who made calculations and reduced astronomical data were known as “computers.” The hours were long and the pay was minimal. Their calculations, however, laid important groundwork for future astronomers and led to some of the most important astronomical discoveries.
Harrison “Jack” Schmitt was the first and last geologist to visit the Moon. Below is his secret chili recipe, served best with a side of tortilla chips and some space history. We can’t help with the chips, but we can tell you a little about this chili-making astronaut.
On this day in 2011, Juno began its journey to Jupiter. After an almost five-year journey, the spacecraft successfully entered Jupiter’s orbit, and has since been investigating the planet's origins, interior structure, deep atmosphere and magnetosphere.
During the Mercury, Gemini, and Apollo missions, one of NASA’s concerns was the safety of its crews, something it monitored rigorously through the use of biomedical instrumentation. As initial flight planning commenced in 1959, biomedical equipment capable of transmitting from space did not exist. NASA quickly brought together medical staff and hardware engineers to develop biomedical technology.
Claudia Alexander was perhaps not well-known to the general public, but within the space and science community she was a valued colleague and friend whose contribution to the field of space exploration was significant and lasting.
Much of the Moon is blanketed by a thick layer of dust, built up from the rocky surface over billions of years by the impacts of small meteorites. Hidden beneath the dust is evidence of ancient geologic activity – great volcanic eruptions, tectonic shifts in the crust, and vast deposits of once-molten material hurled outward during the formation of the giant impact basins.
