NASA plans to 'Touch The Sun' this weekend
If NASA meets its launch date during a 65-minute window before dawn, it will mean the spacecraft's 26 approaches to the sun during its six-year mission could begin in November. The study will spend 7 years. After launch, the spacecraft will orbit directly through the solar atmosphere - the corona - closer to the surface than any human-made object has ever gone.
He added that he is "impressed" by the Parker Solar Probe, calling it "a very complex machine". On Board facilities are a high-quality camera, so soon, scientists will enjoy interesting images.
"Parker Solar Probe uses Venus to adjust its course and slow down in order to put the spacecraft on the best trajectory", said Driesman. Experts hope that the information obtained by the probe will help to examine in more detail the phenomenon.
The Parker Solar Probe is quite small, about the size of a small auto, and it weighs about 1,500 pounds.
No human efforts to study our home star _ telescopes that scan the surface, X-ray observations of the corona, spacecraft that pass over the poles _ have fully answered these questions, said Justin Kasper, a space scientist at the University of MI and leader of a particle-sampling instrument suite.
"But the day we go to Mars, we'll need to be able to predict solar eruptions of these particles, which can be deadly", he told AFP. Talk of such a solar probe, he said, "probably goes back at least 40 years".
It's the first mission ever that will get up close and personal with the sun. At its closest pass, the Parker Solar Probe will experience temperatures as high as 2,500 degrees Fahrenheit. The answer lies in the same fact that keeps Earth from plunging into the Sun: Our planet is traveling very fast - about 67,000 miles per hour - nearly entirely sideways relative to the Sun. For perspective, Earth is about 93 million miles from the center of our solar system.
"All of our data on the corona so far have been remote", said Nicholeen Viall, solar physicist at Goddard. Such particles can interfere with satellite electronics, especially for satellites outside of Earth's magnetic field.
"It's a spacecraft loaded with technological breakthroughs that will solve numerous largest mysteries about our star, including finding out why the sun's corona is so much hotter than its surface", said mission scientist Nicola Fox, with Johns Hopkins University Applied Physics Laboratory.
The probe is created to fly through the outermost part of the sun's atmosphere. By operating so close to the Sun, it will be passing through an environment with enormous radio interference. The historic Parker Solar Probe is expected to "revolutionize our understanding of the sun", where changing winds, bursts, and other events reverberate through the solar system and effect Earth, along with other planets. There is also a white light imager, taking pictures of what the spacecraft is about to "plow through", said Fox.
"We can't agree on what's actually going on", Kasper said.
"This is the first time NASA has named a spacecraft for a living individual", said Thomas Zurbuchen, associate administrator for the agency's Science Mission Directorate in Washington. The Solar Probe Cup, dubbed "the bravest little instrument", is a sensor that will extend beyond the heat shield to "scoop up samples" of the sun's atmosphere, according to Justin Kasper, mission principal investigator and professor of climate, space sciences and engineering at the University of MI.
North Korea Is Building New Missiles
Fifty-five boxes containing the remains of troops who died in the Korean War will now be taken to Hawaii for identification. Defense Secretary Jim Mattis has welcomed the return of the 55 boxes but acknowledged it's not certain who is inside.
Epic Will Keep Fortnite Off Google's Store to Make More Money
However, novice users are typically discouraged from doing so, because apps from unknown sources could pose a security risk. It seems that the rule book for how to release an Android game is going straight out the window when it comes to Fortnite .
Google's new phones could come with a smart Pixel Stand dock
There seem to be two memory variants - one with 4GB of RAM + 64GB of storage and the other using 6GB of RAM + 128GB of storage. If the rumors about the Google-made Pixel Stand are true, this glass back could be used for wireless charging purposes.
