Interstellar missions, after Voyager’s challenge to discover undiscovered space for the United States and China
The Voyager sensors They raised disturbing scientific questions as they moved away from the solar system. Scientists now Johns Hopkins University Applied Physics Laboratory (APL) created a concept for the interstellar probe (IP), $3.1 billion is important Capturing the science challenge launched by the Voyager probe a decade ago after it left the heliosphere, the sun’s area of influence. Few of the Voyager probes expected them to survive for long, yet their remarkable observations continued to emerge, overturning many beliefs about the outer limits of the solar system. The Voyager data are so perplexing that some prominent researchers have said that the probes may not have reached interstellar space yet, possibly because the heliosphere extends farther than previously thought.
He said, “The only way to see what our aquarium looks like is to stand outside and look inside.” Ralph McNutWho worked on the plasma detector for the Voyager mission, NASA’s epic mission on the outer planets It all started in 1977. Now, McNutt needs to convince a jury of his colleagues to get the money to start the business. His team presented the Interstellar Probe Concept Study for the Decadal Survey of Sun and Space Physics, a community exercise led by the National Academies of Sciences, Engineering, and Medicine that will prioritize the field over the next 10 years. The committee is expected to begin deliberations next month and deliver its verdict in 2024. Admiration for intellectual property will go a long way towards ensuring NASA support For the probe, ideally, it would take off in 2036.
In 2007, Voyager 2 presented a big surprise when it fell below the ecliptic plane, the plane at which the planets of the solar system orbit. You go through the so-calledTermination shock‘, where the solar wind begins to falter when it collides with gases and interstellar dust that the solar system passes through on its way to the galaxy. Voyager 1 went through a “termination shock” 3 years ago, about 94 astronomical units (AU) from Earth, where there is 1 astronomical unit The average distance between the Earth and the Sun, that is about 150 million km. However, his plasma detector failed in 1980 during his visit to SaturnSo he could not measure the deceleration of the solar wind. Models expected the wind speed to drop from 1.2 million kilometers per hour to about 300,000 kilometers per hour, but Voyager 2 recorded wind speeds of 540 thousand kilometers per hour. A symbol of how much has been explored and understood about space outside the solar system. Chinese scientists are planning a similar mission called candid among the stars, which can be cast at approximately the same time. “buckle up,” encouraged Jim Bell, a planetary scientist at Arizona State University, Tempe, and former president of the Planetary Society. “It’s a space race to the edge of the solar system!”
