File: 03/26/2012 The GPM High Gain Antenna System (HGAS) in integration and testing at Goddard Space Flight Center. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA). The Core Observatory will link data from a constellation of current and planned satellites to produce next-generation global measurements of rainfall and snowfall from space. The GPM mission is the first coordinated international satellite network to provide near real-time observations of rain and snow every three hours anywhere on the globe. The GPM Core Observatory anchors this network by providing observations on all types of precipitation. The observatory's data acts as the measuring stick by which partner observations can be combined into a unified data set. The data will be used by scientists to study climate change, freshwater resources, floods and droughts, and hurricane formation and tracking. Credit: Craig E.

Held in appendage deploy position, the Hubble Space Telescope's (HST's) high gain antenna (HGA) has been released from its stowed position along the Support System Module (SSM) forward shell. The STS-31 crew aboard Discovery, Orbiter Vehicle (OV) oversees the automatic HGA deployment prior to releasing HST. HST HGA is backdropped against the blackness of space.

The massive high-gain antenna for NASA's Europa Clipper mission is complete. The antenna is nearly 10 feet (3 meters) wide and will be integrated along with other telecommunications hardware into the spacecraft's propulsion module. The antenna will download science data and allow ground controllers to send and receive commands and data between Earth and the spacecraft in Jupiter orbit – more than a million times farther from Earth than the International Space Station's orbits. It was designed by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and aerospace vendor Applied Aerospace Structures Corporation (AASC) in Stockton, California. With an internal global ocean under a thick layer of ice, Jupiter's moon Europa may have the potential to harbor existing life. Europa Clipper will swoop around Jupiter in an elliptical orbit, dipping close to the moon on each flyby to collect data. Understanding Europa's habitability will help scientists better understand how life developed on Earth and the potential for finding life beyond our planet. Europa Clipper is set to launch in 2024. https://photojournal.jpl.nasa.gov/catalog/PIA24899
Areas of rocky Martian terrain are seen in this image, taken by the Imager for Mars Pathfinder (IMP) on Sol 2. Portions of a lander petal and deflated airbag are at lower left. The dark disk at center is the high-gain antenna, and the silver cylindrical objects at upper right are part of the antenna's mechanism. An area of relatively smooth terrain is seen at upper right, which may offer clues to how this area was formed, and may be a future target for Sojourner's studies. The black area at lower right and small strip at top center is missing data. http://photojournal.jpl.nasa.gov/catalog/PIA00625

Engineers and technicians install a 10-foot (3-meter) high-gain antenna on NASA's Europa Clipper spacecraft on Aug. 14, 2023. The orbiter is being assembled in the clean room of the High Bay 1 clean room of the Spacecraft Assembly Facility at the agency's Jet Propulsion Laboratory, in preparation for launch to Jupiter's moon Europa in October 2024. The precision-engineered dish was attached to the spacecraft in carefully choreographed stages over the course of several hours. Europa Clipper will need the huge antenna to transmit data hundreds of millions of miles back to Earth. Scientists believe the icy moon Europa harbors a vast internal ocean that may have conditions suitable for supporting life. The spacecraft will fly by the moon about 50 times while its science instruments gather data on the moon's atmosphere, surface, and interior – information that will help scientists learn more about the ocean, the ice crust, and potential plumes that may be venting subsurface water into space. https://photojournal.jpl.nasa.gov/catalog/PIA25957

NASA's twin MarCO spacecraft are scheduled to make a flyby of Mars on Nov. 26. On Nov. 24, a wide-angle camera on MarCO-B took this picture of the Red Planet, which appears as a small, grey dot in the lower left quadrant of the image. On the right side of the image is the spacecraft's high-gain antenna. On the left side is the high-gain antenna feed, as well as part of the spacecraft's thermal blanket. MarCO-B was approximately 310,000 miles (500,000 km) away from Mars at the time. Mars is actually only about 3 pixels wide in this image, but because of blurring it appears larger. An annotated version of this image notes the location of Mars, the high-gain antenna, high-gain antenna feed and thermal blanket. Each about the size of a briefcase, the MarCO spacecraft are CubeSats, or small satellites built from standardized units that are 4 inches (10 cm) square. (Each MarCO satellite consists of six CubeSat units.) The MarCOs are the first CubeSats to reach deep space, and were the first CubeSats to photograph Mars. https://photojournal.jpl.nasa.gov/catalog/PIA22830

Engineers and technicians use a crane to lift a 10-foot (3-meter) high-gain antenna as they prepare to install it on NASA's Europa Clipper spacecraft on Aug. 14, 2023. The orbiter is being assembled in the clean room of High Bay 1 at the agency's Jet Propulsion Laboratory in Southern California in preparation for its launch to Jupiter's moon Europa in October 2024. The precision-engineered dish was attached to the spacecraft in carefully choreographed stages over the course of several hours. Europa Clipper will need the huge antenna to transmit data hundreds of millions of miles back to Earth. Scientists believe the icy moon Europa harbors a vast internal ocean that may have conditions suitable for supporting life. The spacecraft will fly by the moon about 50 times while its science instruments gather data on the moon's atmosphere, surface, and interior – information that will help scientists learn more about the ocean, the ice crust, and potential plumes that may be venting subsurface water into space. https://photojournal.jpl.nasa.gov/catalog/PIA25956

The first image captured by one of NASA's Mars Cube One (MarCO) CubeSats. The image, which shows both the CubeSat's unfolded high-gain antenna at right and the Earth and its moon in the center, was acquired by MarCO-B on May 9. MarCO is a pair of small spacecraft accompanying NASA's InSight (Interior Investigations Using Seismic Investigations, Geodesy and Heat Transport) lander. Together, MarCO-A and MarCO-B are the first CubeSats ever sent to deep space. InSight is the first mission to ever explore Mars' deep interior. If the MarCO CubeSats make the entire journey to Mars, they will attempt to relay data about InSight back to Earth as the lander enters the Martian atmosphere and lands. MarCO will not collect any science, but are intended purely as a technology demonstration. They could serve as a pathfinder for future CubeSat missions.
