NASA refuses to say goodbye to its old Voyager spacecraft



A spaceship cannot live among the stars forever.

But NASA isn’t quite ready to say goodbye to its 1970s Voyager 2, the second-longest spacecraft to explore beyond the solar system’s outermost planets. It slowly dies as it races through interstellar space at over 34,000 miles per hour.

The Voyager engineering team has already disabled heaters and other energy vampires that are not critical to flight. However, the situation has become more dire. With spacecraft power supply depleted, NASA was on the verge of shutting down one of the five onboard science instruments. This would mark the beginning of the end for long-term scientific mission(will open in a new tab).

At the very last moment, the engineers came up with new plan(will open in a new tab) to squeeze more life out of Voyager 2. At a distance of 12 billion miles, they pinpointed a hidden fount of energy in one of its parts that could prevent them from shutting down a key tool for another three years.

“The scientific data that Voyagers return becomes more valuable the farther they get from the Sun, so we are definitely interested in keeping as many scientific instruments as possible for as long as possible,” said Linda Spilker, project scientist Voyager in NASA Jet Propulsion. laboratories in a statement(will open in a new tab).

Both Voyager 2 and its twin Voyager 1 are almost 45 years old, much older than their satellites. original lifespan(will open in a new tab). They were intended to study Jupiter and Saturn, their satellites and the rings of Saturn. For a two-planet mission, they were only built for five years.

After initial success, engineers doubled mission objectives(will open in a new tab) include two more planets: Uranus and Neptune. Together they explored four planets, 48 ​​moons and many planetary magnetic fields and rings.

The Voyager spacecraft is currently exploring the limits of the Sun’s influence. These are the first probes to travel outside the so-called “heliosphere,” the Sun’s protective bubble of particles and magnetic fields. Gemini is helping scientists answer questions about their role in protecting the Earth from radiation found in the interstellar medium. Scientists define interstellar space(will open in a new tab) as a place outside the constant flow of solar matter affecting its surroundings.

Engineers have found an additional supply of energy in a part designed to protect scientific instruments from changes in their voltage. Electrical fluctuations can potentially damage appliances, so the regulator runs a backup circuit to access the reserved power of its generators. Voyager 2’s instruments will now use the energy instead of putting it aside.

Both Voyager probes are powered by radioisotope thermoelectric generators that convert heat from decaying plutonium(will open in a new tab) into electricity. This process produces less energy every year.

As for Voyager 1, it already uses one less scientific instrument than its brother because one of its instruments failed early in the mission. This means NASA won’t have to decide whether to turn off another one until next year. If this new power strategy works for Voyager 2, the team will consider doing the same for Voyager 1.

Although Voyager 2 now flies without a safety net, engineers are confident that its electricity is relatively stable, which poses little risk to onboard instruments.

“The alternative offers a big reward for keeping the science instruments on longer,” said Suzanne Dodd, Voyager project manager. in a statement(will open in a new tab). “We’ve been watching the spacecraft for several weeks now and this new approach seems to be working.”

Rabbi Harold Kushner, who was seen here on July 10, 2008, managed to express words that resonated with readers around the world and representatives of different religions.

Rabbi Harold Kushner, who has never shied away from answering life’s most painful questions about loss, goodness and God, and in doing so has brought comfort to people around the world, died Friday while at a hospice in Canton, Massachusetts. hey what 88

“He was a giant to our family and an incredibly dedicated father and grandfather who you can rely on for everything. We are happy to know that so many people are mourning with us,” Kushner’s daughter, Ariel Kushner Haber, told NPR.

Kushner’s funeral will take place Monday at Natick Yisrael Temple in Natick, Massachusetts, where he served as a Congregational rabbi for 24 years.

Kushner was born and raised in a predominantly Jewish neighborhood in Brooklyn, New York. He studied at Columbia University and later received rabbinic ordination at the Jewish Theological Seminary in New York in 1960.

Author of 14 books, Kushner is perhaps best known for his title. When bad things happen to good people which he wrote after the loss of his first child.

The tragedy prompted a heartbroken Kushner to turn to the Bible to boldly confront issues of suffering, justice, and the role of an almighty God—a task that many have dared to explain, but very few have responded with as effectively and gracefully as he has.

“God would like people to get what they deserve in life, but He can’t always arrange that. Forced to choose between a good God who is not omnipotent and a powerful God who is not entirely good, the author of the Book of Job chooses to believe in God’s goodness,” Kushner wrote.

Published over four decades ago, the book contained a message that readers should have heard throughout generations: that God’s love is limitless and that God’s supreme plan is for people to live full, bold, and meaningful lives in a world far from perfect.

Kushner’s writings have resonated with readers of various religions.

Other Kushner writings also touched on life’s most difficult questions of goodness, failure, and purpose. Although they were largely based on Jewish theology, his writings resonated with readers from various religions.

After the disastrous events of September 11, 2001, Kushner’s meditation on Psalm 23 became a bestseller, offering guidance on how to find faith and courage in the midst of an unbearable tragedy.

“Most of the time we have no control over what happens to us. But we can always control how we react to what happens to us,” he wrote. “If we can’t choose to be lucky, to be talented, to be loved, we can choose to be grateful, to be happy with who we are and what we have, and to act accordingly.”

In an interview with NPR’s René Montagne in 2010, Kushner admitted that he felt conflicted about the fact that When bad things happen to good people continues to attract new readers.

“I feel a bit conflicted that this continues to resonate because it means more people are facing new challenges of suffering,” he said. “There is always a fresh batch of mourners who ask, “Where was God when I needed him the most?” “

When asked if his relationship with God had changed with age, Kushner, who was 74 at the time, replied in the negative.

“I feel like God and I came to terms with each other a couple of decades ago when he got used to the things I can’t do and I’m resigned to what he can’t do,” he said. “And we still care a lot about each other.”
