NASA releases images of Rosetta Spacecraft’s Philae Lander as it bounced/landed on Comet

NASA - National Aeronautics and Space AdministrationPasadena, CA – Images taken by the Rosetta spacecraft’s OSIRIS imaging system show the portions of the journey its Philae comet lander undertook on November 12th, as it approached and then rebounded off the surface of comet 67P/Churyumov-Gerasimenko.

The mosaic comprises a series of images captured by OSIRIS’s narrow-angle camera over a 30-minute period spanning the first touchdown. The images were taken with Rosetta’s OSIRIS narrow-angle camera when the Rosetta spacecraft was orbiting the comet at about 9.6 miles (15.5 kilometers) from the surface.

The descent of its comet lander Philae was captured by the Rosetta spacecraft's main camera as the lander approached - and then rebounded off - the comet's surface. (ESA/Rosetta/MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA)

NASA reports Rosetta Spacecraft’s target Comet has begun streaming Gas and Dust

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – This image of comet 67P/Churyumov-Gerasimenko, taken by Rosetta’s Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) on September 20th, from a distance of 4.5 miles (7.2 kilometers), shows jets of dust and gas streaming into space from the neck of the comet’s nucleus.

Images of the comet nucleus, taken by Rosetta earlier in the summer, showed that the distinct jets of dust and gas emanating from the comet were originated from the neck region, which connects the comet’s two lobes. Images obtained by OSIRIS now show jets of dust along almost the entire length of the comet.

This image was taken by the Optical, Spectroscopic, and Infrared Remote Imaging System, Rosetta's main onboard scientific imaging system, on Sept. 10, 2014. (ESA/Rosetta/MPS/UPD/LAM/IAA/SSO/ INTA/UPM/DASP/IDA)

NASA releases First MAP of Rosetta spacecraft’s target Comet 67P/Churyumov-Gerasimenko

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists have found that the surface of comet 67P/Churyumov-Gerasimenko — the target of study for the European Space Agency’s Rosetta mission — can be divided into several regions, each characterized by different classes of features. High-resolution images of the comet reveal a unique, multifaceted world.

ESA’s Rosetta spacecraft arrived at its destination about a month ago and is currently accompanying the comet as it progresses on its route toward the inner solar system.

NASA reports Rosetta Spacecraft takes new image of Comet 67P/Churyumov-Gerasimenko showing surface details

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new image of comet 67P/Churyumov-Gerasimenko shows the diversity of surface structures on the comet’s nucleus.

It was taken by the Rosetta spacecraft’s OSIRIS narrow-angle camera on August 7th, 2014. At the time, the spacecraft was 65 miles (104 kilometers) away from the 2.5-mile-wide (4-kilometer) nucleus.

In the image, the comet’s head (in the top half of the image) exhibits parallel linear features that resemble cliffs, and its neck displays scattered boulders on a relatively smooth, slumping surface.

NASA releases new image of Rosetta Spacecraft’s target Comet

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As the ESA’s Rosetta spacecraft closes to within 1000 km of Comet 67P/Churyumov-Gerasimenko, the Rosetta science team has released a new image and made the first temperature measurements of the comet’s core.  The temperature data show that 67P is too hot to be covered in ice and must instead have a dark, dusty crust.

The new image was acquired on August 1st at 02:48 UTC by the OSIRIS Narrow Angle Camera onboard Rosetta at a distance of approximately 1000 km. It shows the rough surface of the double-lobed core in amazing detail.

NASA reports Rosetta spacecraft captures pictures of Coma surrounding it’s target Comet

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Less than a week before Rosetta’s rendezvous with comet 67P/Churyumov-Gerasimenko, images obtained by OSIRIS, the spacecraft’s onboard scientific imaging system, show clear signs of a coma surrounding the comet’s nucleus.

A new image from July 25th, 2014, clearly reveals an extended coma shrouding 67P’s nucleus. “Our coma images cover an area of 150 by 150 square kilometers (90 by 90 square miles),” said Luisa Lara from the Institute of Astrophysics in Andalusia, Spain.

NASA releases new photos of Rosetta Comet

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As the European Space Agency’s Rosetta probe approaches Comet 67P/Churyumov-Gerasimenko (67P) for an August rendezvous, the comet’s core is coming into sharper focus. On Thursday, July 24th, ESA released a new set of images and a striking 3D model of 67P’s nucleus.

The resolution of the latest images taken by the spacecraft’s OSIRIS imaging system on July 20th is 330 feet (100 meters) per pixel. At that resolution, 67P appears to consist of two parts: a smaller head connected to a larger body. The connecting region, the neck, is proving to be especially intriguing.

Comet 67P/Churyumov-Gerasimenko was imaged by the European Space Agency's Rosetta spacecraft on July 20, 2014, from a distance of approximately 3,400 miles (5,500 kilometers). These three images were taken two hours apart. (ESA/Rosetta/MPS for OSIRIS Team/MPS/UPD/LAM/IAA/SSO/INTA/UPM)

NASA says Rosetta Spacecraft discovers target Comet’s center made of two parts

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As the European Space Agency’s spacecraft Rosetta is slowly approaching its destination, comet 67P/Churyumov-Gerasimenko, the comet is again proving to be full of surprises.

New images obtained by OSIRIS, the onboard scientific imaging system, confirm the body’s peculiar shape hinted at in earlier pictures. Comet 67P is obviously different from other comets visited so far.

The images show that comet 67P/Churyumov-Gerasimenko has a two-part shape. (ESA/Rosetta/MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA)

NASA reports Rosetta spacecraft speeding toward target Comet

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Less than half the distance between Earth and moon separates Rosetta from its destination, comet 67P/Churyumov-Gerasimenko. The European Space Agency’s (ESA) spacecraft will become the first to orbit a comet and land a probe on its nucleus. It is beginning observations and sending science data back to Earth.

Recent images from Rosetta’s Onboard Scientific Imaging System (OSIRIS) indicate that the comet is currently at rest — no longer showing signs of an extended dust coma surrounding its nucleus.

This image of comet 67P/Churyumov-Gerasimenko was taken by the Onboard Scientific Imaging System (OSIRIS) on the European Space Agency's Rosetta spacecraft on June 4, 2014. (ESA/Rosetta/MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA)

NASA says Rosetta Spacecraft monitors activity of it’s target Comet

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The target of ESA’s Rosetta mission has started to reveal its true personality as a comet, its dusty veil clearly developing over the past six weeks.

A new sequence of images of comet 67P/Churyumov-Gerasimenko was taken between March 24th and May 4th, as the gap between craft and comet closed from around 3.1 million miles (5 million kilometers) to 1.2 million miles (2 million kilometers). By the end of the sequence, the comet’s coma extends about 800 miles (1,300 kilometers) into space. By comparison, the nucleus is roughly only 2.5 miles (4 kilometers) across, and cannot yet be ‘resolved.’

This sequence of images shows comet 67P/Churyumov-Gerasimenko moving against the background star field. (ESA/Rosetta/MPS)
