The surviving portion of the Deep Impact space probe that watched as its other half smashed into a comet on July 4 is being sent on a mission to study another comet.
NASA is considering an encore for its Deep Impact spacecraft, which made history earlier this month when it smashed a hole in a comet to study its frozen primordial core. The space agency has given scientists the go-ahead to bring the spacecraft closer to Earth's orbit for a potential mission extension.
Data from Deep Impact's instruments indicate an immense cloud of fine powdery material was released when the probe slammed into the nucleus of comet Tempel 1 at about 23,000 miles per hour. The cloud indicated the comet is covered in the powdery stuff.
By Gina Keating PASADENA, Calif. (Reuters) - A spectacular collisionbetween a spacecraft and a comet has freed a huge plume ofprimordial material from the comet's nucleus that could unlockthe secret of how life arrived on Earth, NASA scientists saidon Monday.
By Nichola Groom and Nigel Hunt PASADENA, Calif. (Reuters) - A NASA spacecraft collidedwith a comet half the size of Manhattan late on Sunday night,creating a brilliant cosmic smashup that capped a risky voyageto uncover the building blocks of life on Earth.
By Gina Keating PASADENA, Calif. (Reuters) - The Deep Impact spacecraft hassuccessfully deployed its coffee table-sized "impactor" intothe path of a comet in the final stage of a mission to tracelife on Earth to its celestial origins, NASA scientists said onSunday.
By Nichola Groom and Nigel Hunt PASADENA, Calif. (Reuters) - A NASA spacecraft entered therisky home stretch of its 268 million-mile voyage to crash intoa comet on Sunday, performing its final maneuvers in a missionto uncover the building blocks of life on Earth.
By Nichola Groom PASADENA, Calif. (Reuters) - A NASA spacecraft is "healthyand ready" for its July 4 collision with a comet and hasalready provided images critical to understanding the buildingblocks of life on Earth, officials said on Friday.
NASA's Deep Impact spacecraft continues to sail through its final checkout, as it hurtles toward comet Tempel 1. Impact with the comet is scheduled for 1:52 a.m. EDT, July 4 (10:52 p.m. PDT, July 3).
NASA's Deep Impact spacecraft observed a massive, short-lived outburst of ice or other particles from comet Tempel 1 that temporarily expanded the size and reflectivity of the cloud of dust and gas (coma) that surrounds the comet nucleus.
