The Robert P. Lin Graduate Fellowship will be used to support outstanding graduate students at the University of California, Berkeley who pursue research related to space sciences, including, but not limited to, students with training in Physics, Astronomy or Engineering.
February 17th is the 11 year anniversary of the launch of the Five THEMIS Spacecraft, a two year mission to study space weather.
NASA’s Time History of Events and Macroscale Interactions during Substorms (THEMIS) aims to resolve one of the oldest mysteries in space physics, namely to determine what physical process in near-Earth space initiates the violent eruptions of the aurora that occur during substorms in the Earth’s magnetosphere.
THEMIS is a 2-year mission consisting of 5 identical probes that will study the violent colorful eruptions of Auroras.

After a successful launch on Thursday, Jan. 25, GOLD is now on its way to providing unprecedented images of the Earth’s ionosphere—the boundary between our planet and space.
Also launching this year is the Ionospheric Connection Explorer, or ICON, which will study the ionosphere and neutral upper atmosphere.
But while GOLD flies in geostationary orbit—onboard its host SES Government Solutions communications satellite—more than 22,000 miles above the Western Hemisphere, ICON flies just 350 miles above Earth, where it can gather close-up images of this region.

The systems engineers successfully established communication with the GOLD instrument and its detector doors opened when commanded. After their tests, the engineers powered off the instrument the same day, at 7:40 p.m. EST. The instrument will remain powered off until its host satellite, SES-14, reaches geostationary orbit and GOLD operations commence later this year.
On Wednesday, Jan. 17, NASA’s Parker Solar Probe was lowered into the 40-foot-tall thermal vacuum chamber at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The spacecraft will remain in the chamber for about seven weeks, coming out in mid-March for final tests and packing before heading to Florida.
The thermal vacuum chamber simulates the harsh conditions that Parker Solar Probe will experience on its journey through space, including near-vacuum conditions and severe hot and cold temperatures.
“This is the final major environmental test for the spacecraft, and we’re looking forward to this milestone,” said Annette Dolbow, Parker Solar Probe’s integration and test lead from the Johns Hopkins Applied Physics Lab, which designed, built, and will manage the mission for NASA. “The results we’ll get from subjecting the probe to the extreme temperatures and conditions in the chamber, while operating our systems, will let us know that we’re ready for the next phase of our mission – and for launch.”
During thermal balance testing, the spacecraft will be cooled to -292 degrees Fahrenheit (-180 Celsius). Engineers will then gradually raise the spacecraft’s temperature to test the thermal control of the probe at various set points and with various power configurations.
To protect NASA’s Parker Solar Probe from the intense heat of the Sun’s atmosphere, scientists and engineers developed a revolutionary Thermal Protection System, or TPS. This heat shield, made of carbon-carbon composite material, will experience temperatures of almost 2,500 degrees Fahrenheit (1,370 Celsius) as the spacecraft hurtles through the solar atmosphere, while keeping the instruments on the spacecraft at approximately room temperature.
The heat shield recently moved from the Johns Hopkins Applied Physics Lab (APL) in Laurel, Maryland to NASA’s Goddard Space Flight Center in Greenbelt to undergo testing in their large Thermal Vacuum Chamber. The Thermal Vacuum Chamber will simulate the harsh conditions that the heat shield must endure during the mission: This includes the airless vacuum of space along with huge temperature fluctuations between hot and cold as the spacecraft swings past the Sun and back out into space. The TPS’ ability to withstand extreme temperatures has already been proven through testing at other facilities, as the Thermal Vacuum Chamber at Goddard cannot simulate the very high temperatures of the Sun.
