NASA Launches Four Spacecraft To Study Earth-Sun Magnetism

An anonymous reader writes: Late Thursday NASA used an Atlas rocket to put four new, identical spacecraft into orbit. "The quartet of observatories is being placed into an oblong orbit stretching tens of thousands of miles into the magnetosphere — nearly halfway to the moon at one point. They will fly in pyramid formation, between 6 miles and 250 miles apart, to provide 3-D views of magnetic reconnection on the smallest of scales. Magnetic reconnection is what happens when magnetic fields like those around Earth and the sun come together, break apart, then come together again, releasing vast energy. This repeated process drives the aurora, as well as solar storms that can disrupt communications and power on Earth. Data from this two-year mission should help scientists better understand so-called space weather."

Dying.

Pfffft.

You just weren't invited to the wake. It was a small ceremony.

See the code words here... "weather" and "earth" in the same paragraph. This is going to tick off Ted Cruz and the extreme conservative republican base.

Send him into orbit. It wouldn't be the first time a politician grandstanded from space. Preferable as close as possible to one of these magnetic reconnections. "Don't worry Senator, your faith in god will protect you from the energy of a measly 10^16 pounds of TNT."

Fortunately, the Deep Space Climate Observatory (DSCOVR) made it into space before it could be killed by another republican adminstration.

Oh Really?

[tomhath]

The project was started in 2005, when Republicans controlled both houses of Congress and the White House.

Republicans know that Reagan proved deficits don't matter, but cynically and hypocritically drum up fear of debt when Democrats are in the White House. And Democrats, pussies that they are, fall for it.

Open Source on MMS

[joelsherrill]

RTEMS is used as the real-time operating system on multiple computers in the MMS constellation. It is used on the main flight computers as well as instruments. Details in this post:https://lists.rtems.org/pipermail/users/2015-March/028648.html

Altitude + tetrahedron + ignorance.

Are you surprised or confused?

Actually, in some games, they call the flight formation which would appear to be a triangle a pyramid. Perhaps the writer plays some of those games.

Tap that energy

[Julz]

And at the same time perhaps they will discover how to tap this energy, or at least a small part of it, for efficient power generation.

Oblong Orbit, Anyone?

[the monolith]

Oh, yes! Another quality piece of journalism, but from AP? Really? Link to Article [ap.org] Presumably, the spacecraft will be giving way to traffic coming from the left as well?
