Included is a greeting card showing the coin in flight and a certificate of authenticity.Īll sales support hands-on STEM education The opposite side of the coin shows Neil's iconic footprint on the Moon. Reflected in Buzz's visor are Neil Armstrong, the United States flag, and the lunar lander. The silver dollar is curved and reproduces the helmet of astronaut Buzz Aldrin. The coin was flown to the stratosphere onboard the students' cosmic ray research balloon. You can, however, get one from Earth to Sky Calculus. The US Mint created Apollo 11 silver dollars to celebrate the first Moon landing-but you can no longer buy them from the Mint. Like the original astronauts, this rare Apollo 11 silver dollar has been to space, too: Aurora alerts: SMS TextĪPOLLO 11 PROOF SILVER DOLLAR (COLLECTOR'S ITEM): Fifty-three years ago, Apollo 11 astronauts landed on the Moon. There is still a slim chance that G1-class storms will develop as Earth passes through the CME's wake. Pilots flying commercial jets over the North Atlantic got an eyeful as well. Thomas McCarty saw the display from Fairbanks, Alaska: 'It was the first good show I have seen this season,' he says. Soon after that, almost the entire north half of the sky exploded with colourful auroras.' 'I travelled ~20km away from the city lights, stopped and waited with my camera ready to go. 'I drove out as soon as I noticed the arrival of the glancing CME,' reports photographer Gunjan Sinha of Saskatoon, SK, Canada. The weak impact did not cause a geomagnetic storm, but it did shake things up enough to spark auroras around the Arctic Circle: 2nd.ĬME IMPACT SPARKS AURORAS, BUT NO STORM: As predicted, a CME grazed Earth's magnetic field during the early hours of Aug. The oxygen lines all worked, as did three of the hydrogen lines, but the fourth hydrogen line did not fully open. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining-a result of the yin-yang relationship between the solar cycle and cosmic rays.ĪRTEMIS I LAUNCH SCRUBBED: Today's launch of Artemis I has been scrubbed due to an issue with one of the engines: In the last seconds of the launch countdown, some of the liquid hydrogen and liquid oxygen is diverted to flow around the four engines to cool them in preparation for ignition.

Sunspot AR3089 is developing a 'delta-class' magnetic field that poses a threat for strong Earth-directed solar flares.
