The Parker Solar Probe should be launched August 11, 2018 on a Delta IV Heavy class launch vehicle and an upper stage based on the STAR-48B solid rocket motor. Interplanetary gravity assists will provide further deceleration relative to its heliocentric orbit, which may result in a heliocentric speed record at perihelion. The probe will achieve a velocity of up to 200 km/s (120 mi/s), which will temporarily make it the fastest manmade object, almost three times as fast as the current record holder, Helios-B. At closest approach, Parker Solar Probe will move around the Sun at approximately 430,000 mph (700,000 kph). That’s fast enough to get from Philadelphia to Washington, D.C., in one second.
The probe will start making its first close passes of the sun in 2024. It will have to swing around Venus several times to get the speed and orbits to get closer to the sun.
The Parker Solar Probe will be the first spacecraft to fly into the low solar corona. It will determine the structure and dynamics of the Sun’s coronal magnetic field, understand how the solar corona and wind are heated and accelerated, and determine what processes accelerate energetic particles. The Parker Solar Probe mission design uses repeated gravity assists at Venus to incrementally decrease its orbital perihelion to achieve multiple passes of the Sun at approximately 8.5 solar radii, or about 6 million km (3.7 million mi; 0.040 AU).
Mercury’s distance from the Sun ranges from 46,000,000 to 70,000,000 km (29,000,000 to 43,000,000 miles). The Parker solar probe will get about 8 times closer than Mercury to the sun.
The spacecraft’s systems can survive incident solar intensity 520 times the intensity at Earth orbit by using a solar shadow-shield. The solar shield is 11.4 cm (4.5 in) thick and is made of reinforced carbon–carbon composite, which is designed to withstand temperatures outside the spacecraft of about 1,377 °C (2,511 °F).
The goals of the mission are:
* Trace the flow of energy that heats the corona and accelerates the solar wind.
* Determine the structure and dynamics of the magnetic fields at the sources of solar wind.
* Determine what mechanisms accelerate and transport energetic particles
European Solar Orbiter in 2019 will launch and orbit at 60 solar radii

At the said speeds we could reach the moon in much less than an hour … and that too in a direct flight path …

I doubt that they care.
I preferred the local mum who made $66/hour and was able to buy a brand new MacLaren F1. Work from home , for only 150 000 hours (by my calculation) plus time travel, what more could you want?
It’s a slight advantage because the spammers are wasting their resources.
Are you the lady that earned so much $924 / hr, that you bought a new Land Range Rover? Orare you the babe that bought the emerald green BMW?
Why are they trying to get this close to sun? The satellite will get too hot and burn up!
Instead of doing this during the day, why don’t they swing in close to the sun AT NIGHT? And then they won’t get burned up!
I wouldn’t call that an advantage. The spam is still there, while legitimate discussion is crippled without source links.
No, there are little faces just below each story where you can vote on how the story made you feel. In this case, I think two people were angry that we are taunting Ra the sun god.
One advantage of vuukle is that the lame spam just doesn’t work because the links are stripped out.
Probably someone upset that they aren’t sending it in at night so it won’t get burnt.
I thought those emotion indicators were based on response/reply word choice.

The title makes it sound like it’ll go 25 times closer than ever before, which isn’t correct. The Helios probes reached 0.3 AU. We’ve also visited Mercury, which reaches a similar distance from the Sun at perihelion. This probe will go to 0.04 AU, which is 7.5 times closer than these previous records. The 25 times factor is relative to Earth.
I’m interested in who voted that this news made them angry. And why?
