Several Mars-based NASA spacecraft had prime viewing positions for comet Siding Spring's October 19 close flyby of the Red Planet. Early images included a composite photo from NASA's Hubble Space Telescope that combined shots of Mars, the comet, and a star background to illustrate Siding Spring's distance from Mars at closest approach.

Comet Siding Spring Seen Next to Mars

This composite NASA Hubble Space Telescope Image captures the positions of comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT October 19, 2014. The comet passed by Mars at approximately 87,000 miles (about one-third of the distance between Earth and the Moon). At that time, the comet and Mars were approximately 149 million miles from Earth.

Humans have long dreamed of traveling to Mars, hopscotching across the solar system and fanning out into the cosmos beyond.

Opportunity Views Comet Near Mars

Mars Exploration Rover Opportunity captured images of a comet passing much closer to Mars than any previous known comet flyby of Earth or Mars. The images of comet Siding Spring were taken against a backdrop of the pre-dawn Martian sky on Sunday (Oct. 19).

All three NASA orbiters around Mars confirmed their healthy status Sunday after each took shelter behind Mars during a period of risk from dust released by a passing comet.

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars.

The Look of a Young Mars

This artist's concept depicts the early Martian environment (left) - believed to contain liquid water and a thicker atmosphere - versus the cold, dry environment seen at Mars today (right).

New Image From Mars Orbiter

Four possible landing sites are being considered for the ExoMars mission in 2018. Its rover will search for evidence of martian life, past or present.

Regional dust storm activities over Northern Hemisphere of Mars - captured by Mars Color Camera on-board Mars Orbiter Spacecraft from altitude of 74500 km on Sep 28, 2014 High resolution image.

MAVEN Returns First Mars Observations

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has obtained its first observations of the extended upper atmosphere surrounding Mars.

India's Mars Orbiter Spacecraft has captured its first image of Mars. The image was taken from a height of 7300 km; with 376 m spatial resolution. Larger image. Another image shows the limb of Mars.

India successfully placed its Mars Orbiter Mission spacecraft into orbit around Mars this evening - and in so doing it became the first nation to put something into Mars orbit on its very first attempt.

MAVEN Enters Orbit Around Mars

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars' orbit at 10:24 p.m. EDT Sunday, Sept. 21, where it now will prepare to study the Red Planet's upper atmosphere as never done before. MAVEN is the first spacecraft dedicated to exploring the tenuous upper atmosphere of Mars.

MAVEN Is Ready for Sept. 21 Orbit Insertion

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled Sept. 21 insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles.

NASA's Mars Curiosity rover has reached the Red Planet's Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission's long-term prime destination.

Memory Reformat Planned for Opportunity

An increasing frequency of computer resets on NASA's Mars Exploration Rover Opportunity has prompted the rover team to make plans to reformat the rover's flash memory.

Evaluation of a pale, flat Martian rock as the potential next drilling target for NASA's Curiosity Mars rover determined that the rock was not stable enough for safe drilling.

This HiRISE image shows what is termed a pedestal crater, so-called because the level of the surface adjacent to the crater is elevated relative to the surface of the surrounding terrain.

Space is Dangerous - Be Prepared

Despite their years of training, endless simulations of space flights, and intense study of past flights "we don't know for sure how things are going to work out," said former NASA astronaut Frank Culbertson, a veteran of four shuttle flights and one stint on the International Space Station said at the AIAA SPACE 2014 Forum in San Diego.
