PASADENA, Calif. (NASA PR) — Black magic.

That’s what radiofrequency engineers call the mysterious forces guiding communications over the air. These forces involve complex physics and are difficult enough to master on Earth. They only get more baffling when you’re beaming signals into space.

Until now, the shape of choice for casting this “magic” has been the parabolic dish. The bigger the antenna dish, the better it is at “catching” or transmitting signals from far away.

But CubeSats are changing that. These spacecraft are meant to be light, cheap and extremely small: most aren’t much bigger than a cereal box. Suddenly, antenna designers have to pack their “black magic” into a device where there’s no room for a dish — let alone much else.

PASADENA, Calif. (NASA PR) — A next-generation technology demonstration mission has just passed a big milestone.

The Space Technology 7 Disturbance Reduction System (ST7-DRS) is a system of thrusters, advanced avionics and software managed by NASA’s Jet Propulsion Laboratory, Pasadena, California. It has been flying on the European Space Agency’s LISA Pathfinder spacecraft, which launched from Kourou, French Guiana on Dec. 3, 2015 GMT (Dec. 2 PST). As of Oct. 17, the system had logged roughly 1,400 hours of in-flight operations and met 100 percent of its mission goals.

PASADENA, Calif. (NASA PR) — Mission managers for NASA’s Juno mission to Jupiter have decided to postpone the upcoming burn of its main rocket motor originally scheduled for Oct. 19. This burn, called the period reduction maneuver (PRM), was to reduce Juno’s orbital period around Jupiter from 53.4 to 14 days. The decision was made in order to further study the performance of a set of valves that are part of the spacecraft’s fuel pressurization system. The period reduction maneuver was the final scheduled burn of Juno’s main engine.

PASADENA, Calif. (NASA PR) — NASA’s Jet Propulsion Laboratory in Pasadena, California, has issued a request for proposal (RFP) seeking design, development and build of the robotic spacecraft that will capture a multi-ton asteroid boulder from deep space during the first segment of the agency’s Asteroid Redirect Mission (ARM). The RFP is open to the four industry partners that previously completed conceptual designs of the spacecraft.

PASADENA, Calif. (NASA PR) — NASA’s Juno mission successfully executed its first of 36 orbital flybys of Jupiter today. The time of closest approach with the gas-giant world was 6:44 a.m. PDT (9:44 a.m. EDT, 13:44 UTC) when Juno passed about 2,600 miles (4,200 kilometers) above Jupiter’s swirling clouds. At the time, Juno was traveling at 130,000 mph (208,000 kilometers per hour) with respect to the planet. This flyby was the closest Juno will get to Jupiter during its prime mission.

Juno Approach Movie of Jupiter and the Galilean Moons

Comments

Video Caption: NASA’s Juno spacecraft captured a unique time-lapse movie of the Galilean satellites in motion about Jupiter. The movie begins on June 12th with Juno 10 million miles from Jupiter, and ends on June 29th, 3 million miles distant.

The innermost moon is volcanic Io; next in line is the ice-crusted ocean world Europa, followed by massive Ganymede, and finally, heavily cratered Callisto. Galileo observed these moons to change position with respect to Jupiter over the course of a few nights.

From this observation he realized that the moons were orbiting mighty Jupiter, a truth that forever changed humanity’s understanding of our place in the cosmos. Earth was not the center of the Universe. For the first time in history, we look upon these moons as they orbit Jupiter and share in Galileo’s revelation. This is the motion of nature’s harmony.
