Lockheed Martin 032115 OSIRIS RExz8j A1 Q1 Solar Panels

A1Q1

Today’s your chance to ask us, the OSIRIS-REx team, your #asteroid sample return mission
questions using #askNASA!

@OSIRISREx #asteroid BennuSampleReturn #askNASA Why does #MAVEN #OSIRISREx &
#JupiterExoliner have the same bus but different Solar Panels?

.@TierraUniversu #Maven is at Mars, which is further from the sun than OSIRIS-REx at
#Bennu, it needs larger solar panels for req’d power.

Time to #AskNASA! MT @OSIRISREx: learn about the #asteroid sample return mission! 4:30 p.m.
ET, March 20.

@LockheedMartin #asteroid #askNASA What are the Lifespan of @MAVEN2Mars @OSIRISREx & the
#JupiterExoliner and how far can they go?

.@TierraUniversu For OSIRIS-REx, our design lifetime is 7 years. We will travel over 6
billion km roundtrip.

@TierraUniversu @OSIRISREx: #MAVEN has enough fuel to orbit #Mars for another 9 years,
depending on use as a comm. relay vs. science orbit.

How would you make the Internet more Secure Free and Safe?

[–]jimmywales1JIMMY WALES[F] 2 points an hour ago
I’d like to see much more widespread use of encryption. I would like to have a web browser that doesn’t
even support ‘http’ as a protocol, using only ‘https’. A few years ago that was thought to be
impractical because of the cost of encryption. That cost has fallen dramatically, though, so I think
now it’s possible to get there.
And it is the direction we are headed, I believe, as more and more people understand that it’s silly to
go around spewing data when we don’t have to.

Auroras

[–]Universu 2 points 10 hours ago
Are there changes in the appearance of Auroras in relation to climate change?

[–]Dr_Liz_MacDonald[F,S] 2 points 9 hours ago
Interesting question. The aurora occurs very high up in the atmosphere, basically on the edge of space.
Weather and climate effects tend to occur much lower. So there’s nothing I can think of that would
affect the look of auroras.

[–]Dr_Liz_MacDonald[F,S] 2 points 8 hours ago
Weather occurs less than 10 miles up, and aurora more than 60 miles up!

As reported today MAVEN saw a Martian Aurora, how are Earth’s Auroras different or similar to other
planet’s auroras?

[–]Dr_Liz_MacDonald[F,S] 2 points 8 hours ago
Great question. Several other planets have magnetic fields and atmospheres, thus they have aurora. One
of the members of the Aurorasaurus Scientist Network (a great group of volunteers) wrote a blog post
about this a few months ago. Check it out: http://blog.aurorasaurus.org/blog/are-there-auroras-on-
other-planets/

[–]Dr_Liz_MacDonald[F,S] 2 points 8 hours ago
Scientists can compare the aurora seen on other planets to try to learn more about Earth and vice
versa. This helps to test our understanding of the plasma physics at work all around our magnetosphere.
Aurora on Earth has characteristic colors and occurs over a specific range of height due to the density
and species with our upper atmosphere. The magnetic field strength and orientation with respect to the
spin plane also varies significantly at other planets.

I read it for a creative project last year (I got to pick my own book to read) and for the project I
made a house of cards because of the constant theme that society wants peace and constantly wants to be
organized, but only because the higher ups don’t want to deal with the poorer masses, and that its hard
to move up in a society designed to make the rich richer and not help the poor.

DANNY: My favorite book of all time is THE GREAT GATSBY. Every word in that is exquisitely chosen. The
plot leaves something to be desired, I think, but the language… I always get turned on by wonderful
use of language. That’s why I’m such a big Paul Simon and Bob Dylan fan.
DARREN: My favorite books of late all seem to be historical non-fiction, for some reason. Books like
David McCullough’s JOHN ADAMS, and I’m just now getting into the Robert Caro Lyndon Johnson books…

What advise can you give to people to live despite all of the unfavorable odds?

[–]GhostBoyMartin[F,S] 2 points an hour ago
What advise can you give to people to live despite all of the unfavorable odds?
Life can be really tough and I have enormous compassion for people who have to struggle and fight
against the odds. I would say that there is always hope no matter how faint and distant it may seem. I
also don’t think there is anything wrong with feeling hopeless the key is not to get stuck in that
feeling – one way or another, nothing lasts forever. Enjoy life as much as possible. You can learn to
appreciate the small simple, yet most important things in life: being together with the people you
love, the feel of warm sunshine on your skin, the taste of food you love, the sound of music. Most
people nowadays are caught up with always looking forward, never being in the moment and I think that
illness and adversity are hard experiences which can also teach you about the beauty of life – the
beauty of the moment. Those of us who get to learn this are lucky in many ways.

What other techniques are an alternative to 3-person IVF/mitochondrial transfer?

[–]Prof_Paul_KnoepflerProf. of Cell Biology|UC-Davis|Stem Cell Biology[F,S] 2 points an hour ago
I’m glad you asked about alternatives. That’s an important element here. The main alternative is
pre-implantation genetic diagnosis. Via this technology, many times (but not always), parents can
screen embryos early on and select those that are most likely not to have mitochondrial disease. This
technology itself isn’t perfect, but it is a viable option for many. Another option is adoption or
using a donor egg (the resulting offspring would only be genetically related to the dad), but
understandably, some folks want to have their own “biological” children. Another option is waiting 5
-10 more years for the needed animal studies to teach us more that we need to learn before using this
in humans.

How will NetNeutrality affect the future of OneWeb and the SpaceXGoogle space internet?

[–]PublicKnowledgeDC[F,S] 4 points an hour ago
to the extent that either will qualify as US broadband access service providers (and I’m not sure
either one would), they would be prevented from discriminating just like any other ISP. However, this
is where that “reasonable network management” stuff becomes important. It could be that these
services could impose restrictions on users that other ISPs could not, if those restrictions were
really tied to technological limitations of their network.
