NASA Administrator Bolden visits Space Sciences Lab

On Thursday May 8th the U.C. Berkeley Space Sciences Lab was honored to have NASA Administrator Charles Bolden and his Deputy Chief of Staff Mike French (Cal Alumni) stop by for an informational visit and tour of our facilities

Dr. Stuart Bale presented the history of our lab and the high success rate of the 75 missions that we have flown scientific instruments on, including Space Shuttle missions, Explorer Satellites, Sounding Rockets and High Altitude Balloons.

Two upcoming missions and one current mission were discussed with Administrator Bolden and his team. MAVEN’s current transition from Earth to Mars was championed by Dr. Dave Mitchell, discussing data already being collected by the suite of instruments developed by the lab and upcoming science once we arrive at Mars. ICON’s science objectives were highlighted by Dr. Thomas Immel and Dr. Bale discussed the upcoming Solar Probe mission and the challenges that are faced in its design and observations that will take place as it orbits the sun. Laura Peticolas also discussed the Educational Outreach that our lab participates in to spread the word and get students interested in science.

Administrator Bolden then toured various parts of our lab including the great view overlooking the Bay and Golden Gate, Deployable Booms with Paul Turin, Wire Booms and sphere Preamps with Dr. Bonnell, the GRIPS and COSI Balloon program with Ben Maruca, and Carolyn Kierans, the SSL MOC or Mission Operations Center with Bryce Roberts, Mark Lewis and Dan Cosgrove, and finally the Stardust lab with Anna Butterworth and Andrew Wesphal.

Van Allen Probes Achieve Mission Success


MAVEN Launch

On March 26, 2014, NASA declared the Van Allen Probes mission—designed to explore and unlock the mysteries of Earth’s radiation belts—an official success. “Not only has the Van Allen Probes mission met its requirements for mission success, it has exceeded them,” said NASA’s Mona Kessel, but “there is much more data to gather, analysis to be done, understanding to be gained, and mysteries to be solved.”

MAVEN Trajectory and Cruise Phase to Mars Orbit Insertion


Satellite Missions destined for Mars – MAVEN, Mars Science Lab and Mars Rovers, launch only about every two years. The reason being the proximity of the Earth to Mars at mission launch so that the satellite catches up to the red planet in the shortest time possible.

This animation, courtesy of Dave Folta/GSFC, shows the cruise trajectory of the MAVEN spacecraft, which was launched on Nov. 18, 2013. It will arrive at Mars on Sept. 21, 2014, to explore the planet’s upper atmosphere, ionosphere and interactions with the Sun and solar wind. The range and speed of MAVEN with respect to Earth, Mars and the Sun, both in metric (kilometers) and Imperial (miles) units, is displayed along with a date and the number of days until arrival at Mars.

The Sun-centered trajectory of MAVEN, shown in blue, takes 308 days to transit from Earth’s orbit in green, to Mars’ orbit in red. The animation updates at a rate of twice per day and shows the MAVEN spacecraft, Earth and Mars locations.

Scientists say destructive solar blasts narrowly missed Earth in 2012

Fierce solar blasts that could have badly damaged electrical grids and disabled satellites in space narrowly missed Earth in 2012, U.S. researchers said on Wednesday.

The event, detected by NASA’s STEREO A spacecraft, is the focus of a paper that was released in the journal Nature Communications on Tuesday by Luhmann, China’s State Key Laboratory of Space Weather professor Ying Liu and their colleagues.

Scientists Discover “Zebra Stripes” in Inner Radiation Belt

VAPScientists at Johns Hopkins Applied Physics Lab have discovered a new, persistent structure in Earth’s inner radiation belt using data from the twin NASA Van Allen Probes spacecraft. Most surprisingly, this structure is produced by the slow rotation of Earth, previously considered incapable of affecting the motion of radiation belt particles, which have velocities approaching speed of light.

Deep Space Network Tracks MAVEN Spacecraft

A new visualization product out of the NASA’s Jet Propulsion Lab, JPL, allows users to monitor the real time status of communications with our deep space explorers, including MAVEN.

MAVEN (displayed as “MVN”) is communicating to ground operators via various antenna’s depending on the earth’s rotation, from DSS-43, the Deep Space Network’s 70-meter antenna in Canberra, Australia or DSS-65 in Madrid Spain. According to the “Deep Space Network Now” visualization, MAVEN is approaching a distance of 25 million km from Earth. Others explorer craft with SSL associations are, SOHO, STEREO – STA or STB. Click on the antenna to bring up the spacecraft and its specifics.
