NASA | Parker Solar Probe: It’s Surprisingly Hard to Go to the Sun

The Parker Solar Probe will be the first-ever mission to “touch” the Sun, traveling directly into the Sun’s atmosphere about 4 million miles from the surface. Read the story: NASA launch schedule:
The Sun contains 99.8 of the mass in our solar system. Its gravitational pull is what keeps everything here, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion miles away.
But even though the Sun has such a powerful pull, it’s surprisingly hard to actually go to the Sun: It takes 55 times more energy to go to the Sun than it does to go to Mars. Why is it so difficult? 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 — almost entirely sideways relative to the Sun. The only way to get to the Sun is to cancel that sideways motion.
Since Parker Solar Probe will skim through the Sun’s atmosphere, it only needs to drop 53,000 miles per hour of sideways motion to reach its destination, but that’s no easy feat. In addition to using a powerful rocket, the Delta IV Heavy, Parker Solar Probe will perform seven Venus gravity assists over its seven-year mission to shed sideways speed into Venus’ well of orbital energy. These gravity assists will draw Parker Solar Probe’s orbit closer to the Sun for a record approach of just 3.83 million miles from the Sun’s visible surface on the final orbits.
Though it’s shedding sideways speed to get closer to the Sun, Parker Solar Probe will pick up overall speed, bolstered by Sun’s extreme gravity — so it will also break the record for the fastest-ever human-made objects, clocking in at 430,000 miles per hour on its final orbits.

#NASA #Parker #Solar #Probe #Surprisingly #Hard #Sun
USA USA earth and sky MOLGA™ # moon was easy
Jesus makes the moon … MOLGA™
No Comment … MOLGA™ Science Bible
Ola Dr. Obrigada Perla informacao
earth is not a spinning ball going around the sun.
we can not leave earth
earth is a closed system (bill nye the science guy)
the sun is much smaller and much closer then they tell us.
nasa lies
NASA is a true story. ~ MOLGA™
None of us can be sure to be around in 7 years to celebrate, so NASA, please make that rocket go faster and I am sure you know how, just do it.
First stop Showing Orange Color Of Sun :/
I read a under comment
They said a heat shield but I want to know that what material that it’s made for the heat shield
Corona just about more than 3million degree celcius
t — one day
can’t wait
good luck
Does it have solar panels
We will talk about the physicist (Alan Guth) His theory of the oversized universe
. The theory of an oversized universe predicts multiple universes
.We want you to search for more scientific evidence about the enlarged universe
.Look for evidence in the cosmic background radiation Twilight of the Big Bang
1 — Look for those first gravitational waves in cosmic background radiation
2 — Look for an area far beyond the Twilight of the Big Bang
3 — Look for the initial waves Heavy
. We ask you to work on these three proposals
For the discovery of multiple universes
Bahahaha you have to be a moron to believe this
The question is why is it so hard to get to the moon.
People need to leave things alone if something goes wrong were all screwed dont say i warned you listen to god for once
background noise = down thumb
I am very eager to know the mysteries of sun
Another successful Launch yesterday it was Awesome and I’m so looking forward to this mission and what can be learnt from our most powerful star the SUN. Why has it taken so long to send a probe to the SUN? the first mission to the SUN will be fascinating to watch what happens
hey nasa , is there any news about stars , we heard that the largest star even known is CANIS MAJORIS . did u guys found bigger then that ?
lol , is all this a joke?
Parker estas demente xdxd
Put big shaq here
Cuz he is not hot
You’re shooting something half a million miles an hour at 97% of the mass of our Solar system. Do we get to know anything you’re doing in regards to Time dilation research?
430000 mph… so this will be the fastest human made object so far.
Someone has been watching too many Danny Boyle science fiction movies
Cool
Should go at night..
