Power of 620 W at the encounter is provided by a 7.2 square meter solar array and stored in a small NiH2 battery. The spacecraft control system consists of four hemispherical resonator gyros, two star trackers, reaction wheels, and hydrazine thrusters. Pointing accuracy is 200 microradians with 65 microradian knowledge. Thermal control is achieved by insulating blankets, surface radiators, finishes, and heaters. The spacecraft has two redundant RAD750 computers with 309 MB each of memory for scientific data.

The Impactor

The impactor projectile is made of primarily copper (49%) and only 24% aluminum so it will be easily identifiable and minimize contamination in the spectra after the projectile is largely vaporized and mixed in with the comet ejecta on impact. The impactor is a short hexagonal cylinder built above the copper cratering mass. It has a small hydrazine propulsion system for targeting which can provide delta-V of 25 m/s. Targeting is accomplished using a high-precision star-tracker, auto-navigation algorithms, and the Impactor Targeting Sensor (ITS), a camera which provides images for autonomous control and targeting. The ITS will operate until impact, and images will be sent back to Earth via the flyby spacecraft. Damage to the instrument due to dust in the coma may make imaging impossible duing the last minute or so before impact. Communication with the flyby spacecraft is via S-band. The impactor is mechanically and electrically connected to the flyby spacecraft until 24 hours prior to encounter. After separation it runs on internal battery power.

Mission Profile

Deep Impact launched on 12 January 2005 at 18:47:08.574 UT (1:47:08 p.m. EST) on a Delta II. The spacecraft transferred into a heliocentric orbit and will rendezvous with comet P/Tempel 1 in July 2005.

The video, showing a cat named Taters chasing a laser, traveled at the speed of light, where it was received at Caltech’s Palomar Observatory. Because of the great distance the laser had to travel, the team needed to aim the transmission at where Earth would be when the signal arrived. In Receiver Riddle, use pi to determine where along Earth's orbit the team needed to aim the laser so that it could be received at the Observatory at the correct moment. This animation shows how DSOC's laser signals are sent between the Psyche spacecraft and ground stations on Earth - first as a pointing reference to ensure accurate aiming of the narrow laser signal and then as a data transmission to the receiving station. Credit: NASA/JPL-Caltech/ASU| Watch on YouTubeDaring DeflectionIn 2022, NASA crashed a spacecraft into the asteroid Dimorphos in an attempt to alter its orbit. The mission, known as the Double Asteroid Redirection Test, or DART, took place at an asteroid that posed no threat to our planet. Rather, it was an ideal target for NASA to test an important element of its planetary defense plan. DART was designed as a kinetic impactor, meaning it transferred its momentum and kinetic energy to Dimorphos upon impact, altering the asteroid's orbit. In Daring Deflection, use pi to determine the shape of Dimorphos’ orbit after DART crashed into it. This image shows the final minutes of images leading up to the DART spacecraft's intentional collision with asteroid Dimorphos. Credit: NASA/Johns Hopkins APL | › Enlarge image Orbit ObservationThe NISAR mission is an Earth orbiting satellite designed to study our planet's changing ecosystems. It will collect data about Earth's land- and ice-covered surfaces approximately every 6 days, allowing scientists to study changes at the centimeter scale – an unprecedented level of detail. To achieve this feat, NISAR will collect massive amounts of data. In Orbit Observation, students use pi to calculate how much data the NISAR spacecraft captures during each orbit of Earth. The NISAR satellite, shown in this artist’s concept, will use advanced radar imaging to provide an unprecedented view of changes to Earth’s land- and ice-covered surfaces.
