The four-person crew who will fly on the all-private Polaris Dawn mission — set to include the first commercial spacewalk and the debut of SpaceX’s extravehicular spacesuit — will begin training this month for their ride on a Dragon spacecraft to an altitude more than three times higher than the International Space Station.
Mars' Carbon Dioxide Glaciers are on the Move
In 1666, famed Italian astronomer and mathematician Giovanni Cassini (the man who discovered four of Saturn’s largest moons) observed the Martian polar ice caps for the first time. However, it was not until the late-18th century, when Sir William Herschel recorded his own observations, that the connection to Earth’s own ice caps was established. In his subsequent treatise, “On the remarkable appearances at the polar regions on the planet Mars” (1784), noted how the southern cap grew and shrunk due to seasonal changes.

What’s the Best Way to Build Landing Pads on the Moon?
In the near future, NASA, the European Space Agency (ESA), China, and Roscosmos all mount crewed missions to the Moon. This will constitute the first time astronauts have walked on the lunar surface since the Apollo Era. But unlike the “Race to the Moon,” the goal of these programs is not to get their first and leave only a few experiments and landers behind (i.e., “footprints and flags” missions) but to establish a sustained human presence on the lunar surface. This means creating habitats on the surface and in orbit that can be used by rotating crews.
