UCLA’s ELFIN A and ELFIN B satellites were successfully launched this weekend and we have established contact with both satellites!

MAE Associate Professor Richard Wirz is one of the CO-I’s on the project (https://elfin.igpp.ucla.edu/faculty/) and this is big news for MAE since many MAE students participated in the project. Here is a link to the student team (notice all the AEs and MEs): https://elfin.igpp.ucla.edu/student-team/. Also, here is a link to ELFIN alumni, many of which are MAE: https://elfin.igpp.ucla.edu/alumni/. Almost all participated as undergrads.
With the successful launch of their ELFIN satellites, UCLA students’ work studying space weather is just beginning

For the dozens of UCLA students, faculty, staff and alumni braving the chilly temperatures near Vandenberg Air Force Base on Saturday morning, the brilliant ray of white that radiated across the predawn horizon was the best goodbye ever.
At 6:02 a.m. a Delta II rocket lifted off from the base in Lompoc, California, carrying ELFIN — twin micro-satellites, each weighing about eight pounds and roughly the size of a loaf of bread — into orbit aboard NASA’s ICESat-2 mission.
Saturday’s launch was the culmination of years of planning, dreaming, fabricating, designing, assembling, testing and programming, virtually all of it done by more than 250 UCLA students, most of whom were undergraduates.
“It’s really been a very emotional moment for a lot of students here,” said Ethan Tsai, UCLA graduate student in electrical engineering and ELFIN’s project manager. Tsai, more than two dozen other current students, alumn and faculty, including Vassilis Angelopoulos, professor of space physics and ELFIN’s principal investigator, watched from the VIP area.
“There’s half of my brain that’s trying to stick with the professional mode … and then part of me is just like I can’t believe this thing is launching and I can’t believe this thing is in space,” Tsai said. “I don’t know that it’s sunk in yet. But it’s really emotional for me.”
Luis Frausto, 34, a 2010 UCLA mechanical engineering graduate, who worked on early prototypes of ELFIN, said he was in “total awe” watching the launch from a public viewing site near Vandenberg Middle School.
Frausto, now a design engineer at TAE Technologies, Inc., was one of more than 200 (a record for the Vandenberg public viewing site, according to a base spokesman) who braved the chilly temperatures, including about 40 UCLA ELFINers and a few of their friends, who counted down to zero as the launch went off, sending the crowd into cheers and applause.
“You can’t compare it to watching it on TV. It was like a feeling inside my chest, like I was out of breath,” said Frausto, who left his home in Irvine at 12:30 a.m. to drive the 200 miles northwest to Lompoc. “I’m here and I’m honored to be around everyone who worked on ELFIN.”
ELFIN, which stands for Electron Losses and Fields Investigation CubeSats, is designed to help scientists better understand magnetic storms in near-Earth space. These storms are a typical form of “space weather” that is induced by solar activity, including flares and violent solar eruptions. Magnetic storms can result in damage or even destruction of orbiting satellites that humans depend on for GPS, communications and weather monitoring. Space weather research is also crucial for space tourism and space exploration.
Another former ELFINer who came out was Mike Lawson, who works at the Jet Propulsion Laboratory in Pasadena on the Mars 2020 mission. Lawson slept only two hours on a couch at UCLA before he left Westwood at midnight for what he described as an “emotional” drive on U.S. 101 that included listening to David Bowie’s “Starman.”
“It’s weird. It’s surreal. It was 10 years gone in like 20 seconds,” said Lawson, who earned his bachelor’s degree and Ph.D. in geology from UCLA. The 37-year-old was one of the original ELFINers 10 years ago who worked on prototypes for what would become the satellites that launched this morning. Work began five years ago on the actual satellites that went into orbit, aboard NASA’s final Delta II rocket mission.
Jessica Artinger, an astrophysics major who will begin her fifth year at UCLA this fall, left at 1 a.m. from Fountain Valley in Orange County to make the trip. Since fall quarter 2017, Artinger has led the fabrication team.
“Watching this,” said Artinger, who prior to the launch had expected to cry but despite the dry eyes was nevertheless moved, “my time here means something.”
Louise Tamondong, who is part of ELFIN’s flight operations team, said she got chills watching the launch, which was easily visible for just a few seconds before the rocket was shrouded in thick clouds. About 10 seconds after the sky lit up, the crowd finally heard the roar of the rocket’s engines.
“It felt so unreal that everything that we worked for is going into space … it only felt real when we saw that bright light and everything going up,” said Tamondong. After liftoff, she headed back to Westwood to listen for the first signal from the orbiting ELFIN through an antenna on the roof of UCLA’s Knudsen Hall. They received a signal around 4:30 p.m., confirming that both probes survived the bumpy ride to orbit. The team will now begin commissioning the spacecraft systems and instruments to prepare for the science operations phase.
As a new Bruin, Sixue Xu wasn’t part of the team that designed, tested and built ELFIN. But the graduate student in space physics will be among those who stand to benefit from ELFIN’s work.
“Now it’s our turn,” Xu said, “to make that data into science.”

This morning my alarm went off at 4:30am so that I could go watch and photograph the last Delta II rocket launch out of Vandenberg. Its main payload is a @nasa satellite, but two small satellites named ELFIN were piggybacking a ride into orbit. @elfinucla was designed and built by students in our lab at UCLA in the @uclaepss dept, with much guidance and support from @swansong_ . I'm sure they are super excited about the successful launch! . I am on my way to a wedding in San Diego right now (literally editing in car), so I couldn't make the drive up to Lompoc to watch, meaning I had to get creative. I was happy to find three other photographers at my spot, so we could all listen to NASA TV together during the countdown. We got a view of the launch with the city in the foreground, the city where ELFIN was created. . The cloud on the left is the exhaust plume visible thanks to the rising sun. We got that treat due to a 16 minute delay in the launch time. . I utilized the #getolympus Live Composite feature to capture the full launch. The camera takes an initial picture based on your settings, and then adds new light pixels via stacking images taken with the same settings. It's awesome, and you can watch in live time as the picture updates with each exposure. . I didn't factor in that the sun rises so fast, so the exposure I took initially (which was good) got too bright by the end of the approximately four minutes of launch. Because of this I did some post in photoshop. The feature is phenomenal, though. (Image better on big computer screen of course, IG is tough. ) .
