Jeff Bezos<\/a>‘ space venture has ever undertaken for a paying customer. It also would be the company’s first launch of any kind since its inaugural \u200cNew Glenn flight in January.<\/p>\n“However, due to highly elevated solar activity and its potential effects on the EscaPADE spacecraft, NASA is postponing launch until space weather conditions improve,” the company said on its website on Wednesday.<\/p>\n
New Glenn, a two-stage, heavy-lift rocket 32 stories tall, had been slated for blastoff on Sunday from the U.S. Space Force Station in Cape Canaveral, \u2060Florida, carrying two Mars-bound EscaPADE satellites \u200cin its payload bay. But the flight ended up scrubbed for the day because of heavy cloud cover.<\/p>\n
The mission had been rescheduled for Wednesday, but Blue Origin indefinitely called off the launch again after \u200dalerts for a severe geomagnetic storm were posted by the U.S. Space Weather Prediction Center. The storm was unleashed by a surge in high-energy charged particles spewed into space from large eruptions on the sun’s surface called “coronal mass ejections.”<\/p>\n
The resulting stream of charged-particle radiation,\u200b or plasma, was measured on Earth on Wednesday at G-4, or “severe” levels, one step \u200cdown from the highest stage of G-5 or “extreme.” The geomagnetic storm was forecast to persist at severe strength on Thursday.<\/p>\n
Geomagnetic storms are known to disrupt radio and satellite communications. They also can increase atmospheric density, creating intense friction or drag on satellites and other spacecraft in low-Earth orbit, as occurred in February 2022 when 40 Starlink satellites newly launched by SpaceX were disabled.<\/p>\n
Elevated levels of charged particles from the sun can also more easily escape Earth’s protective magnetic field and collide more vigorously with molecules \u2060in the atmosphere, heightening the extent of colorful aurora displays visible in \u200bthe night skies, mostly in polar regions.<\/p>\n
The vibrant green and pink displays \u200bof Northern Lights, or Aurora Borealis, were reported across unusually large swaths of the United States on Tuesday night as far south as Texas, Florida and Alabama, with another round of higher-latitude appearances \u200dforecast for Wednesday.<\/p>\n
Ironically, the twin \u2060satellites of EscaPADE, short for Escape and Plasma Acceleration and Dynamics Explorers, are intended to study similar phenomena on Mars at the end of a 22-month voyage to the Red Planet.<\/p>\n
The two spacecraft, dubbed Blue and Gold, \u2060are designed to orbit Mars in tandem to analyze how streams of charged solar particles interact with Mars’ relatively weak magnetic field and how that interaction has caused \u200cthe planet to lose much of its atmosphere over billions of years.<\/p>\n
