NASA - Venus Bridge
« on: 11/23/2017 07:53 PM »
In the Science article Armed with tough computer chips, scientists are ready to return to the hell of Venus:
Quote
Another test of [NASA Space Flight Center] Glenn's silicon carbide electronics could potentially come quite soon: a proposal called Venus Bridge Orbiter and Surface Science (V-BOSS), one of two candidates for a quick-to-fly, low-cost (less than $200 million) "Venus Bridge" mission that NASA's associate administrator for science, Thomas Zurbuchen, asked Venus scientists to prepare in the wake of the failed Discovery [13/14] round. While details of the V-BOSS won't be set until early next year, it would build off of the LLISSE and add an orbiter to relay lander data back to Earth.

In this presentation at the 12th Low-Cost Planetary Missions Conference, Pasadena, CA, August 15, 2017
Venus Bridge: A Smallsat Program Through the Mid-2020s, by Robert Grimm (SwRI), James Cutts (JPL), Martha Gilmore (Wesleyan U.), Robert Herrick (U. Alaska), Gary Hunter (GRC), Noam Izenberg (APL), Kandis Lea Jessup (SwRI), and Robert Lillis (UCB)

VEXAG was directed in Feb 2017 by NASA’s Science Mission Directorate Associate Administrator (T. Zurbuchen) to determine if useful Venus exploration can be performed within a $200M cost cap.

A “Venus Bridge” Focus Group was chartered to consider ideas on architectures, technology, and science that
could be pursued by one or more small missions launching in the early-to-mid 2020s.

The opportunity to study the feasibility of implementing linked missions and demonstrating or developing new technology within the defined cost cap were key aspects of the charter.
And
Quote
Perform Two Studies of Linked Orbital and In Situ Elements

Orbiter + surface element (lander): GRC / COMPASS

Orbiter + atmospheric element (probe or aerial platform): JPL / Team X.

The two orbiters will be configured with different strawman instruments.

Element linkage as single package, single launch, or separate launches.

Delivery to Venus most likely from fly-by or separation from other interplanetary injection.

James Cutts is also listed as on the "Venus Exploration Roadmap Topical Analysis Group and Venus Bridge Focus Group" on the VEXAG "About Us" page https://www.lpi.usra.edu/vexag/about-us/ .

Also, there's the VEXAG 2017 Town Hall meeting: https://www.lpi.usra.edu/vexag/meetings/Townhall-LPSC-2017/Presentation.pdf

And, there's the Venus Science & Exploration: Decadal Mid-Term Status, The Venus Exploration Analysis Group (VEXAG) at: http://sites.nationalacademies.org/cs/groups/ssbsite/documents/webpage/ssb_180559.pdf

What is the other candidate mission mentioned, but not named, in the Science article quote?

You want to be inspired by things. You want to wake up in the morning and think the future is going to be great. That's what being a spacefaring civilization is all about. It's about believing in the future and believing the future will be better than the past. And I can't think of anything more exciting than being out there among the stars.

Between the computer chips and 'steampunk' (for lack of an astute yet flamboyant description of mechanical clockwork computing), it seems reasonable to reattempt a visit to Venus.  I think the trick might be to focus on simple missions, at least for anything that lands.  Even without the aforementioned developments, orbiting Venus and entering its atmosphere are currently achievable; the DaVinci proposal would have been interesting for one.

While chemistry seems to be the biggest interest, I'd be more interested in the interior of Venus so we can properly see how it compares to Earth; indeed how two Earths can differ in more than atmosphere and location.  Between the eschewed (if just nonexistent) plate tectonics, massive lava cataclysm that resurfaced the planet within the last billion years, and missing magnetosphere, those already imply something's not Earthlike inside.  That'd be my justification for, at least with landers, attempting seismology first while leaving chemistry and other investigations to orbiters and balloons.

What would be needed to arrange a seismometer package on Venus, assuming either 'hot chips' or 'steampunk' methods in as simple yet useful a device as possible?
