This time-lapse video shows the integration of instruments into the ICON payload at the Space Dynamics Laboratory in Logan, Utah. The video covers a 15-week period from mid-February, 2016 until the end of May, 2016. Occasional darkness indicates cleanliness inspections using a UV light, and the blue tower that is occasionally visible is the last tracker used for alignment measurements. The video begins with preparation of the Payload Interface Plate (PIP), with purge lines and the MIGHTI fiber optic assembly. The order of instrument integration is as follows: MIGHTI B, MIGHTI A, ICP-Echo, MIGHTI cal lamp, MIGHTI ebox, IVM A, EUV, FUV, IVM B, star tracker and antenna mast simulators, and ICP flight. The video ends with the payload moved from the handling cart to the shipping container base, ready for testing.
Mark your calendars for the Annual Novato Space Festival, Sunday August 6th, from 10:00 AM to 4:00 PM. Meet legendary Astronauts from the Apollo, Space Shuttle and International Space Station Programs.
NEW THIS YEAR…
EARLY ENTRANCE at 9:30am for families with CHILDREN 12 & UNDER
You’ll get to browse the exhibit area first,
THEN you’ll get to meet Astronaut Jerry Ross and he will read to you from his children’s book!
Data coming back from orbit seemed to not make sense. The glow at the equator changed from place to place around the Earth in ways we didn’t expect. Now we are building the ICON mission, a satellite that will explore this region of the atmosphere, where Earth’s weather meets space weather…It really takes a huge number of people working together to make a space science mission.
Dr. Manfred Bester, Manager of Mission Operations Center at the Space Sciences Lab of UC Berkeley, explains what he and his team do to prepare for the upcoming ICON launch.

As NASA’s Parker Solar Probe spacecraft begins its first historic encounter with the sun’s corona in late 2018—flying closer to our star than any other mission in history—a revolutionary cooling system will keep its solar arrays at peak performance, even in extremely hostile conditions.
Every instrument and system on board Parker Solar Probe (with the exception of four antennas and a special particle detector) will be hidden from the sun behind a breakthrough thermal protection system (TPS)—an eight-foot diameter shield that the spacecraft uses to defend itself against the intense heat and energy of our star.
Every system will be protected, that is, except for the two solar arrays that power the spacecraft. When the spacecraft is closest to the sun, the solar arrays will be receiving 25 times the solar energy they would while orbiting Earth, and the temperature on the TPS will reach more than 2,500°F (1,370°C). The cooling system will keep the arrays at a nominal temperature of 320°F (160°C) or below.

“MAVEN has made tremendous discoveries about the Mars upper atmosphere and how it interacts with the sun and the solar wind,” said Bruce Jakosky, MAVEN principal investigator from the University of Colorado, Boulder. “These are allowing us to understand not just the behavior of the atmosphere today, but how the atmosphere has changed through time.”
During its 1,000 days in orbit, MAVEN has made a multitude of exciting discoveries. Here is a countdown of the top 10 discoveries from the mission:
10. Imaging of the distribution of gaseous nitric oxide and ozone in the atmosphere shows complex behavior that was not expected, indicating that there are dynamical processes of exchange of gas between the lower and upper atmosphere that are not understood at present.
9. Some particles from the solar wind are able to penetrate unexpectedly deep into the upper atmosphere, rather than being diverted around the planet by the Martian ionosphere; this penetration is allowed by chemical reactions in the ionosphere that turn the charged particles of the solar wind into neutral atoms that are then able to penetrate deeply.

Five years ago, on June 13, 2012, Caltech’s Fiona Harrison, principal investigator of NASA’s NuSTAR mission, watched with her team as their black-hole-spying spacecraft was launched into space aboard a rocket strapped to the belly of an aircraft. The launch occurred over the Kwajalein Atoll in the Marshall Islands. Many members of the team anxiously followed the launch from the mission’s operations center at the University of California, Berkeley, anxious to see what NuSTAR would find.
Now, Harrison shares her take on five of the mission’s many iconic images and artist—ranging from our flaring sun to distant, buried black holes. NuSTAR is the first telescope capable of focusing high-energy X-rays—and it has taken the most detailed images of the sky in this energy regime to date.

The Parker Solar Probe, our first mission to touch the sun, was renamed on May 31st in honor of astrophysicist Eugene Parker. Here is a short video showing the mission and its objectives.
