2011: The year in space

THERE ARE LOTS OF EXCITING happenings coming up in space this year. Here’s just a sample of what we can expect.

On February 14-15, NASA’s Stardust probe will do a fly-by of comet Tempel 1. It’ll be looking for damage done by the Deep Impact spacecraft, which fired a projectile into the comet back in 2005.

Also there’ll be the launch of Glory, an Earth-orbiting spacecraft that’ll make readings of black carbon and aerosols in the atmosphere, and measure the amount of incoming sunlight. Plus there’ll be the final flight of the space shuttle Discovery, on a mission to the space station.

March will see NASA’s MESSENGER spacecraft go into orbit around Mercury, the first probe to do so. A largely unknown world, the closest planet to the Sun is sure to hold some surprises. That month will also mark 25 years since Europe’s Giotto probe gave us our first close-up look at a comet, the famous Halley.

In April there’ll be a bunch of anniversaries, the 30th of the first space shuttle launch, the 40th of the first space station launch (which was the Soviet’s Salyut 1), and the biggie, the 50th anniversary of the flight of Vostok 1, carrying Yuri Gagarin, the first person to go into outer space.

April will also see the last flight of space shuttle Endeavour. And it could be the final shuttle mission of all. An extra flight by Atlantis in June has been approved but not yet funded, so we’ll just have to wait and see. Also in June, some parts of Australia will catch a short glimpse of a lunar eclipse.

July will see the second flight of the new, private Dragon spacecraft, designed to take cargo and eventually people to the International Space Station. Its first short test flight last year went perfectly. Dragon could end up being the replacement for the space shuttle.

Also in July, NASA’s Dawn spacecraft will sidle up to the 530km-wide asteroid Vesta, and go into orbit. It’ll spend a year investigating it before heading off to do the same thing with the even larger asteroid Ceres, which is actually known as a dwarf planet these days.

August will see the launch of Juno, NASA’s new unmanned mission to study the planet Jupiter. It’ll take about five years to get there. And the following month will see NASA launch GRAIL, a pair of satellites that’ll orbit the Moon and map its gravitational field, which will help scientists work out its inner structure.

In November, Russia will launch Fobos-Grunt, a mission to the larger of the two Martian moons, Phobos. All going well, it’ll touch down, grab some samples, and blast off back to Earth with them. The Chinese are piggybacking a small satellite too, which will orbit Mars and study its atmosphere, ionosphere and surface.

Finally, in December, there’ll be another launch of that Dragon capsule, plus the first launch of its competitor, called Cygnus. And to top it off, we’ll have another lunar eclipse.
