Comet Hitchhiker

Catching a ride from one solar system body to another isn’t easy. You have to figure out how to land your spacecraft safely and then get it on its way to the next destination. The landing part is especially tricky for asteroids and comets, which have low gravitational pull.

A concept called Comet Hitchhiker, developed at NASA’s Jet Propulsion Laboratory, …

Astronomers tinkering with ice and organics in the lab may have discovered why comets are encased in a hard, outer crust.

Using an icebox-like instrument nicknamed Himalaya, the researchers show that fluffy ice on the surface of a comet would crystalize and harden as the comet heads toward the sun and warms up. As the water-ice crystals form, becoming denser …

NASA engineers are developing climbing legs for the International Space Station’s robotic crewmember Robonaut 2 (R2), marking another milestone in space humanoid robotics.

The legless R2, currently attached to a support post, is undergoing experimental trials with astronauts aboard the orbiting laboratory. Since its arrival at the station in February 2011, R2 has performed a series of tasks to demonstrate …

The Planet Mars

Ripped apart by tectonic forces, Hebes Chasma and its neighbouring network of canyons bear the scars of the Red Planet’s early history.

ESA’s Mars Express has flown over this region of Mars on numerous occasions, but this new eight-image mosaic reveals Hebes Chasma in full and in greater detail than ever.


Location of Hebes Chasma, at about 1°S / 284°E, …

Acquired by ESA’s Planck space telescope, the most detailed map ever created of the cosmic microwave background – the relic radiation from the Big Bang – was released yesterday revealing the existence of features that challenge the foundations of our current understanding of the Universe.

The image is based on the initial 15.5 months of data from Planck and is …

Findings from NASA’s Dawn spacecraft reveal new details about the giant asteroid Vesta, including its varied surface composition, sharp temperature changes and clues to its internal structure. The findings were presented today at the European Geosciences Union meeting in Vienna, Austria and will help scientists better understand the early solar system and processes that dominated its formation.


These composite images …

A full-scale test version of the Orion spacecraft is one of several NASA-sponsored exhibits that will appear alongside space shuttle Discovery at the National Air and Space Museum’s Steven F. Udvar-Hazy Center near Washington Dulles International Airport in Chantilly, Va.


This artist’s rendering represents the crew module of the Orion crew exploration vehicle with the outer skin removed revealing the …

Astronomers are actively hunting a class of supermassive black holes throughout the universe called blazars thanks to data collected by NASA’s Wide-field Infrared Survey Explorer (WISE). The mission has revealed more than 200 blazars and has the potential to find thousands more.


This artist’s concept shows a “feeding,” or active, supermassive black hole with a jet streaming outward at nearly …

NASA is extending three missions affiliated with the Jet Propulsion Laboratory in Pasadena, Calif. — Kepler, the Spitzer Space Telescope and the U.S. portion of the European Space Agency’s Planck mission — as a result of the 2012 Senior Review of Astrophysics Missions.


From left to right, artist’s concepts of the Spitzer, Planck and Kepler space telescopes. NASA extended Spitzer …

Supernova explosions and the jets of a monstrous black hole are scattering a galaxy’s star-making gas like a cosmic leaf blower, a new study finds. The findings, which relied on ultraviolet observations from NASA’s Galaxy Evolution Explorer and a host of other instruments, fill an important gap in the current understanding of galactic evolution.


Time is running out for the …
