SpaceX founder Elon Musk kept his Twitter followers in the loop as the investigation ensued, and wrote, "Falcon 9 experienced a problem shortly before first stage shutdown. Will provide more info as soon as we review the data."
He later added there was an "overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause."
On Monday morning, he said the cause is still unknown after "several thousand engineering-hours of review. Now parsing data with a hex editor to recover final milliseconds."
Minnehaha Academy has yet to comment on the unfortunate mission, but did compose the following tweet the day before the rocket blew up.
Minnehaha's International Space Station (ISS) Team has an experiment set to launch tomorrow morning from Kennedy Space Center! How cool!

The rocket explosion is disappointing, but we agree w/NASA about their program and our students' experiments, "this will not deter us..."— Minnehaha Academy (@MinnehahaAcad) June 29, 2015
