Closing summary
In a White House address, Joe Biden tried to reassure Americans about what fighter jets shot down over North America in recent days, saying there were no signs the still-unidentified objects were connected to China or used for surveillance. Earlier in the day, a Georgia court released portions of a special grand jury’s report into Donald Trump’s election meddling campaign, which indicated jurors were worried about being lied to, but did not reveal if they think the former president or his allies committed crimes. The ball is now in Atlanta-area district attorney Fani Willis’s court, since she’s using the document to determine the next steps in her investigation of the former president’s attempt to overturn his 2020 election loss in Georgia.
Here’s what else happened today:
Senator John Fetterman checked himself into the hospital to receive treatment for depression. The Democrat’s election in Pennsylvania last November was crucial to the party gaining an outright majority in the Senate.
Biden wants to speak with China’s president Xi Jinping after the spy balloon incident, though it’s not clear when the leaders plan to jump on the phone.
Nikki Haley thinks Trump could pass one of the “mental competency tests” she wants to force politicians older than 75 to take.
Democrats are beginning to worry that Biden is too old to run for re-election.
A bill to prevent police from using search warrants to access data from menstrual tracking apps failed in Virginia’s legislature, apparently due to interference from Republican governor Glenn Youngkin.
A theory has emerged from the amateur radio community about what exactly a US jet shot down over Canada’s Yukon territory.
The unidentified object, one of three downed by American planes in recent days, may have been a “pico” balloon equipped with a GPS module and a solar panel that was launched from Illinois last October, and in the middle of circumnavigating the earth for the seventh time, according to this report on hobbyist website RTL-SDR.
As the article makes clear, the details of the K9YO-15 amateur radio balloon and US and Canadian authorities’ description of the object encountered on 11 February sure seem to line up:
The launch blog post indicates that the K9YO-15 balloon was flying a silver mylar 32” sphere SAG balloon which appears to be this one from balloons.online. Unlike latex or rubber weather balloons which inflate and stretch as they rise into lower atmospheric pressures, these mylar balloons can’t stretch, so their fully inflated ground size will be the same as their size at high altitudes, meaning the pico balloon won’t get much bigger than 32”. The payload was a GPS module, Arduino, SI5351 used as a WSPR and APRS transmitter and a solar panel, all together weighing 16.4 grams. A pentagon memo notes that the object shot down over Canada was a “small metallic balloon with a tethered payload” which fits the description of the pico balloon exactly.
The K9YO-15 balloon ceased all WSPR telemetry transmissions while flying just below Alaska since Feb 11 00:18 UTC (just before sunset in Alaska when the solar panels would stop working).
By using NOAA wind models and the last known location by Alaska, K9YO-15 was projected to have been over Yukon when the US Air Force shot down the unknown balloon object at Feb 11 20:41 UTC (3:41 PM EST / 1:41 PM Yukon time according to Canadian Defense Minister Anand). Reports put the altitude of the shot down object at approximately 40,000ft (~12000 meters), which matches the projected ~11500 meters of K9YO-15. Based on the previous days transmission times, it is suspected that if it were operational, the balloon would have begun transmitting again sometime later in the Yukon afternoon when the sun was stronger, but no transmissions have been seen.
