Solar Probe Plus
« on: March 01, 2017, 09:41:28 am »
If someone already has an existing thread, please move this there.

Launch is scheduled for summer of 2018 unless there have been snags since this news update last July.

Next flight up for the Delta IVH & only the second non-classified civilian flight for the launcher since it has been in regular service after the Orion boilerplate test flight.

I think that Solar Probe was an idea first proposed back in the 1950s, although it could have been 1964. It took a long time for a bunch of things to happen to make it possible. That included technology development, but also time for enough people to declare that it was important to do.

The concepts have evolved a lot. Back around 2006 or so the concept for Solar Probe involved several RTGs (nuclear batteries) because they did not know how to use solar panels that close to the sun. There was some technology development that enabled them to come up with high temperature systems so they could do the mission with solar.

If you want to see some clever design, look into the design for the solar panels on SP+. The panels actually retract as they get close to the sun, but they have small tips that still stick out a little bit to provide some power.

There were allot solar probes proposals in 1960s and 1970s

Most used RTGs (nuclear batteries) because the detour to get to sun via Jupiter !
there it get sling shot by Jupiter gravity toward the sun.
after a 5 year trip the probe would burn up as it approach Sun surface

Renamed to "Parker Solar Probe"

I was hoping for something cool like "Sundiver."

Sundiver has some horrible thermodynamics.  (The "refrigerator laser" is a nonsense concept, basically.)

Before someone ask "Sundiver" ?

That's from Sci-fi Novel by David Brin
were manned spacecraft "Sundiver" work on sun surface for explore the "sun-ghosts"
they use "refrigerator laser" to cool down the Spacecraft

"refrigerator laser" are used in physics experiment
were atomic and molecular samples are cooled down to near absolute zero by the interaction with laser beam.
it was proposed several time as cooling system for spacecraft, but no working prototype yet.
biggest problem is to  upend the machinery so exterior is cooled not the internal core..

Hi,

Slightly off topic so please be kind for this parenthesis.
John Mastin, in 1909, devised the first "concept" of a flying machine plunging through the Sun: an airship.
And even further back, right in the middle of the 17th century, Savien Cyrano de Bergerac also devised a conceptual crystal-like or glass-looking spaceship to visit the Sun.
The English translation exhibits a remarkable plate (see attachment) which is still barely known, and reprinted in Dream Machines.

Well, just my two cents.

And yes, again, I do know this is slightly off topic. But these very old advanced propulsion and exploratory concepts found in early sci-fi are part of a pet project I've pursued over the last 30 years. And I couldn't help posting something about that here.

So… just enjoy.

A.

200 km per second. Whew. Fastest man made object ever.

Parker Solar Probe Gets its Revolutionary Heat Shield: Time Lapse

NASA.gov Video
Published on Sep 26, 2017


In this time-lapse video taken on Sept. 21, 2017, the thermal protection system – the heat shield -- for NASA’s Parker Solar Probe spacecraft is shown during installation at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. This 4.5-inch thick, eight-foot diameter shield protects the spacecraft and its instruments against the intense heat and energy of the Sun’s outer atmosphere, the corona, through which the spacecraft will fly on a mission of extreme exploration. The thermal protection system is made of a carbon-carbon composite material with a special outer coating that will reach temperatures of nearly 2,500 degrees Fahrenheit. The heat shield was placed on the probe for a test of alignment as part of integration and testing, but it will soon be removed.  Both spacecraft and shield will continue separate testing processes and then be re-integrated just before launch in summer 2018.

Lasers Fired At NASA's Parker Solar Probe

NASA Goddard
Published on Dec 6, 2017

NASA's Parker Solar Probe is in the midst of intense environmental testing at NASA's Goddard Space Flight Center in Greenbelt, Maryland, in preparation for its journey to the Sun. These tests simulate the noise and shaking the spacecraft will experience during its launch from Cape Canaveral, Florida, scheduled for 2018.

Parker Solar Probe’s integration and the testing team must check over the spacecraft and systems to make sure everything is still in optimal working condition after experiencing these rigorous conditions – including a check of the solar arrays, which will provide electrical power to the spacecraft.

Parker Solar Probe will explore the Sun's outer atmosphere and make critical observations that will answer decades-old questions about the physics of stars. The resulting data will also help improve how we forecast major eruptions on the Sun and subsequent space weather events that can impact life on Earth, as well as satellites and astronauts in space. The mission is named for Eugene N. Parker, whose profound insights into solar physics and processes have helped shape the field of heliophysics.
