Robotic probes launched by NASA, the European Space Agency (ESA), and others are gathering information all across the solar system. We currently have spacecraft in orbit around the Sun, Mercury, Venus, Earth, Mars, and Saturn -- and one new rover recently landed on Mars. Several others are on their way to smaller bodies, and a few are heading out of the solar system entirely. Although the Space Shuttle no longer flies, astronauts are still at work aboard the International Space Station, performing experiments and sending back amazing photos. With all these eyes in the sky, I'd like to take another opportunity to put together a recent photo album of our solar system -- a set of family portraits, of sorts -- as seen by our astronauts and mechanical emissaries. This time, we have some great shots from the new Mars rover Curiosity, a parting shot of the asteroid Vesta, some glimpses of Saturn and its moons, and lovely images of our home, planet Earth.

Yesterday, the efforts of 406 NASA team members and 3,500 Jet Propulsion Laboratory workers, with the help of teams from seven other countries, safely landed a one-ton nuclear-powered rover on the surface of Mars. The complex sequence of landing maneuvers required to slow the massive spacecraft went according to plan, at the end of which a rocket-suspended sky crane gently touched Curiosity down. Moments after landing, the rover sent images, confirming safe arrival, and setting off celebrations by team members and viewers around the world -- at home, alone, or together in viewing parties. Gathered here is a collection of images of the landing, along with new images from the surface of Mars. [31 photos total]

More than eight months ago, on November 26, 2011, NASA launched its newest rover named Curiosity from Florida's Cape Canaveral, headed to the planet Mars. Now, after traveling hundreds of millions of kilometers, the landing is scheduled to take place at 1:31 am Eastern Time on Monday, August 6 (10:31 pm August 5, Pacific Time). The capsule containing the rover will experience "seven minutes of terror", decelerating through the Martian atmosphere, as a series of entry events quickly take place, ending with a rocket-powered sky crane lowering the rover gently to the surface. Curiosity is a beast of a rover, weighing one ton, measuring ten feet long by seven feet tall (at the top of the mast), and powered by a plutonium-238 fueled electrical generator. The rover carries ten instruments, including several high-resolution cameras, and a laser-induced breakdown spectroscopy instrument called ChemCam that can vaporize tiny amounts of minerals and analyze their components. If all goes according to plan, Curiosity is scheduled for a stay on Mars of about 668 Martian sols, or nearly two Earth years, starting in Gale crater. Researchers hope to use the tools on Curiosity to study whether the area in Gale crater has had environmental conditions favorable for supporting microbial life and for preserving clues about whether life existed. (Most of these photos were featured in a November, 2011 entry, when Curiosity was launched). [36 photos total]

On July 4, scientists working with data from ongoing experiments at the Large Hadron Collider (LHC) announced the discovery of a new particle "consistent with" the Higgs boson -- a subatomic particle also colloquially referred to as the "God particle." After years of design and construction, the LHC first sent protons around its 27 kilometer (17 mile) underground tunnel in 2008. Four years later, the LHC's role in the discovery of the Higgs boson provides a final missing piece for the Standard Model of Particle Physics -- a piece that may explain how otherwise massless subatomic particles can acquire mass. Gathered here are images from the construction of the massive $4-billion-dollar machine that allowed us peer so closely into the subatomic world. [34 photos total]

Earlier today, a Soyuz-FG rocket lifted off from the Baikonur Cosmodrome in Kazakhstan, carrying an International Space Station (ISS) crew into orbit. Baikonur, Russia's primary space launch facility since the 1950s, is the largest in the world, and supports multiple launches of both manned and unmanned rockets every year. With the U.S. manned space program currently on hold, Baikonur is now the sole launching point for trips to the ISS. Gathered here is a look at the facility, some of the cosmonaut training programs in Star City outside of Moscow, and a few recent launches and landings -- plus a bonus: 3 spectacular long-exposure images of Earth from the ISS.

Having last traveled to low Earth orbit in March 2011, NASA's Space Shuttle Discovery took to the skies one last time yesterday, piggybacking on a modified Boeing 747. The shuttle left Florida and landed just outside of Washington, D.C., where it will join the collection at the Smithsonian Institution's National Air and Space Museum. Discovery, the fleet leader of NASA's orbiters, flew 39 successful missions over 27 years, accumulating 365 total days in space. Tomorrow, a welcome ceremony is planned at the Smithsonian's Steven F. Udvar-Hazy Center in Chantilly, Virginia. Gathered here are images from Discovery's last flight. [30 photos total]

If all goes well, tomorrow morning at approximately 10:02 a.m. Eastern time (GMT-5), NASA will launch its newest rover named Curiosity from Florida's Cape Canaveral, headed on a nine-month trip to the planet Mars. The $2.3 billion mission will send a capsule into the Martian sky in August of 2012. After decelerating in the atmosphere, a series of entry events will quickly take place, ending with a rocket-powered sky crane lowering the rover gently to the surface. Curiosity is a beast of a rover, weighing one ton, measuring ten feet long by seven feet tall (at the top of the mast), and powered by a plutonium-238 fueled electrical generator. The rover carries ten instruments, including several high-resolution cameras, and a laser-induced breakdown spectroscopy instrument called ChemCam that can vaporize tiny amounts of minerals and analyze their components.

Researchers hope to use the tools on Curiosity to study whether the area in Gale crater has had environmental conditions favorable for supporting microbial life and for preserving clues about whether life existed. I will update this entry with more photos later, after the launch takes place. [30 photos total]
