Laurie Leshin‚ Director of NASA's Jet Propulsion Laboratory‚ Talks With Science

Laurie Leshin was appointed director of NASA's Jet Propulsion Laboratory on May 16. After the successful landing of the Perseverance rover on Mars‚ the JPL is gearing up for several NASA flagship missions‚ including the campaign to collect rock samples from Perseverance. She talked with Science about her experience at JPL and her vision for the agency's future. Here‚ she shares her insights on the space exploration process.

NASA will end the epic interstellar voyages of its Voyager probes when it switches off their systems. Scientific American reported. They were launched in 1977 45 years ago and have continued to push the limits of space exploration. Their distance from Earth is greater than that of any man-made object. This record will probably remain unbroken for many decades. Scientific American stated that the decision to lower power for probes was made to prolong their lives and bring them up to 2030. Ralph McNutt from the Johns Hopkins University Applied Physics Laboratory said that they have given 10 times as much warranty to these darn things. He was referring back to initial projections that the mission would take them four years. The probes are powered by Radioactive plutonium has been keeping the onboard computers running since decades. Scientific American stated that the energy used in the system has been decreasing by approximately 4 Watts per year. This requires energy consumption to be reduced. We might be able to extend the missions into 2030 if everything is going well. The power is all that matters. This is the limit‚ Linda Spilker (a NASA Jet Propulsion Laboratory planetary scientist) told Scientific American. In a Voyager probe image taken on August 23‚ 1981‚ the false colors of Saturn's rings can be seen.NASA They were designed to fly past - a primary mission they accomplished quickly. They kept on going and sent back pictures of the solar system‚ as well as beaming data from deep space. Voyager 1 captured the famous composite photo in 1990. It was a picture of Earth that was taken from 3.7 billion miles above our sun. Pale Blue Dot‚ a photo of Earth that was taken by NASA's Voyager 1 on February 14‚ 1990 at a distance 3.6 billion miles is now available for rerelease. This is a rerelease in 2020.NASA/JPL-Caltech The video below shows more striking images taken by probes.

Voyager 1 was established in 1998. Farthest Human-made objects in space -- approximately 6.5 billion miles away from Earth. Now‚ the probes are 12 billion to 14.5 billion miles from Earth. Live tracker from NASA shows. This is far beyond the solar system's limits. Voyager 1 and Voyager 2 reached interstellar spaces‚ making them the first humans objects to achieve this feat in human history. Hardwired electronic instruments have lasted a long time‚ despite their age. These primitive computers are not very powerful and don't require much electricity. Voyager stores all data collected on the probes. Eight-track tape recorder Scientific American stated that the machine used about half as much energy to send it down to Earth as a regular refrigerator light bulb. Spilker stated that they have less memory than the key fob which opens your car's door. This eight-track machine stores the data of the mission.

It was cutting edge when it launched.NASA/JPL NASA will have to make decisions about which instruments get power as the energy aboard is decreasing. Voyager's ability to communicate with Earth will probably cease after 2030. However‚ this does not necessarily mean that Voyager's mission is over. Both carry 12-inch records‚ which are gold-plated and contain information about Earth. This includes. 115 images ; greetings in 55 different languages; sounds the total time‚ which includes wind‚ rain and the human heartbeat. Music. NASA's Golden Record‚ aboard the Voyager probes.NASA/Insider Scientific American stated that it will take another 22‚000 years for the probes to pass Proxima Centauri with the time capsule of human existence.
