This is an artist's concept depicting a view of comet Wild 2 as seen from NASA's Stardust spacecraft during its flyby of the comet on Jan. 2, 2004. http://photojournal.jpl.nasa.gov/catalog/PIA06283

ER-2 Starlink Thermal Imagery: Fork Fire, Lake County, CA (Clear Lake)
On January 2, 2004 NASA's Stardust spacecraft made a close flyby of comet Wild 2 (pronounced "Vilt-2"). Among the equipment the spacecraft carried on board was a navigation camera. This is the 34th of the 72 images taken by Stardust's navigation camera during close encounter. The exposure time was 10 milliseconds. The two frames are actually of 1 single exposure. The frame on the left depicts the comet as the human eye would see it. The frame on the right depicts the same image but "stretched" so that the faint jets emanating from Wild 2 can be plainly seen. Comet Wild 2 is about five kilometers (3.1 miles) in diameter. http://photojournal.jpl.nasa.gov/catalog/PIA05571

NASA Mariner 2 was the world first successful interplanetary spacecraft. Launched August 27, 1962, on an Atlas-Agena rocket, Mariner 2 passed within about 34,000 kilometers 21,000 miles of Venus.

This image shows the comet Wild 2, which NASA's Stardust spacecraft flew by on Jan. 2, 2004. This image is the closest short exposure of the comet, taken at an11.4-degree phase angle, the angle between the camera, comet and the Sun. http://photojournal.jpl.nasa.gov/catalog/PIA06285

The solid rocket motor for mating to the United Launch Alliance Delta II launch vehicle is lifted up at the Vertical Integration Facility (VIF) at Space Launch Complex 2 on June 14, 2018, at Vandenberg Air Force Base in California. The solid rocket motor will be attached to the rocket. NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will launch on the final Delta II rocket. ICESat-2 will measure the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. The satellite will carry a single instrument, the Advanced Topographic Laser Altimeter System. ICESat-2 will help scientists investigate why, and how much our planet's frozen and icy areas, called the cryosphere, is changing in a warming climate.

The Delta II second stage for NASA Orbiting Carbon Observatory-2 mission, or OCO-2, is lifted to the top of the mobile service tower at Space Launch Complex 2 on Vandenberg Air Force Base in California.

This composite image was taken by the navigation camera during the close approach phase of Stardust's Jan 2, 2004 flyby of comet Wild 2. Several large depressed regions can be seen. Comet Wild 2 is about five kilometers (3.1 miles) in diameter. To create this image, a short exposure image showing tremendous surface detail was overlain on a long exposure image taken just 10 seconds later showing jets. Together, the images show an intensely active surface, jetting dust and gas streams into space and leaving a trail millions of kilometers long. http://photojournal.jpl.nasa.gov/catalog/PIA05578

These images taken by NASA's Stardust spacecraft highlight the diverse features that make up the surface of comet Wild 2, showing a variety of small pinnacles and mesas seen on the limb of the comet and the location of a 2-kilometer (1.2-mile) series of aligned scarps, or cliffs, that are best seen in the stereo images. http://photojournal.jpl.nasa.gov/catalog/PIA06284

NASA EPOXI mission spacecraft obtained these views of the icy particle cloud around comet Hartley 2. The image on the left is the full image of comet Hartley 2 for context, and the image on the right was enlarged and cropped.
NASA EPOXI mission took this image of comet Hartley 2 on Nov. 2, 2010. The spacecraft will fly by the comet on Nov. 4, 2010. The white blob and the halo around it are the comet outer cloud of gas and dust, called a coma.

This image was taken during the close approach phase of NASA Stardust Jan 2, 2004 flyby of comet Wild 2. It is a distant side view of the roughly spherical comet nucleus.

This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on NASA's Voyager 2 narrow angle camera. The images were taken at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach. The picture shows the Great Dark Spot and its companion bright smudge; on the west limb the fast moving bright feature called Scooter and the little dark spot are visible. These clouds were seen to persist for as long as Voyager's cameras could resolve them. North of these, a bright cloud band similar to the south polar streak may be seen. http://photojournal.jpl.nasa.gov/catalog/PIA01492

The second half of the United Launch Alliance (ULA) Delta II rocket payload fairing is being prepared for the move to the Vertical Integration Facility at Space Launch Complex 2 at Vandenberg Air Force Base in California, on June 4, 2018. NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will launch later this year on the final Delta II rocket. ICESat-2 will measure the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. The satellite will carry a single instrument, the Advanced Topographic Laser Altimeter System. ICESat-2 will help scientists investigate why, and how much our planet's frozen and icy areas, called the cryosphere, is changing in a warming climate.

CAPE CANAVERAL, Fla. – Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, a ground support technician assists with removal of a bearing from the B truck tread of crawler-transporter 2, or CT-2. New roller bearing assemblies will be installed. Work continues in high bay 2 to upgrade CT-2. The modifications are designed to ensure CT-2’s ability to transport launch vehicles currently in development, such as the agency’s Space Launch System, to the launch pad. The Ground Systems Development and Operations Program office at Kennedy is overseeing the upgrades. For more than 45 years the crawler-transporters were used to transport the mobile launcher platform and the Apollo-Saturn V rockets and, later, space shuttles to Launch Pads 39A and B.
