Emerging Space Technology Workshop
Brown University

Desktop ∆V was a 1-day workshop focused on the topic of safe propulsion systems that can be assembled and tested in a university or similar engineering laboratory setting.
The workshop was hosted in Providence, RI at the Brown University School of Engineering with sponsorship from the NASA Space Grant Consortia of Rhode Island.
In parallel we
collaborated in real time with
a mirror workshop at Strathclyde University, Glasgow,
Scotland taking place the same day.
As with previous workshops, we enjoyed spirited interchanges among those developing hardware technology and those developing mission applications.

Workshop Details
Workshop registration is open to anyone able to bring relevant insight and expertise to an active discussion on the topic of Desktop ∆V propulsion and related space mission applications.
By invitation university students may attend with registration fees waived and lodging support to US citizen students traveling from a distance funded by the NASA Space Grant Consortia of Rhode Island.
See the Student Invitations for details.
US citizenship is not required to participate in the workshop. However, due to long-established restrictions written into NASA grants, student funding provided by the Rhode Island Space Grant Consortia is limited to US citizens.
Whether or not a US citizen, please refer to the last section below regarding ITAR considerations.
For any reason anticipated or otherwise, at all junctures we remain the final arbiters for who may or may not attend.
Fees
Through February 6, 2011, online registration will be $195. Beginning February 7th, online registration will be $250.
Registration the day of the meeting will also be $250.
The registration fee covers all workshop sessions, continental breakfast prior to the workshop and lunch in the Chancellor's Dining Room. Lunch will be buffet style and also includes vegetarian selections.
Registration fees are non-refundable.
For questions or concerns about any aspect of workshop registration please contact us.
Parallel Workshop with the University of Strathclyde
To challenge our thinking, offer added points of view and more easily include those from the EU into the discussion, this year we have instituted overlapping meetings, one taking place at Brown University and a second at the University of Strathclyde, Glasgow, Scotland, with dialog between the two during the day.
Workshop Architecture
A critical mass of participation is lost in events involving a large number of attendees.. As with our previous workshops, we have set a limit of 50 paid participants plus ten sponsored university students from around the country.
(Please see below for student
invitation details).
Desktop ∆V continues our highly
effective
conference
The Problem To
build satellite
projects quickly, inexpensively and
creatively students,
hobbyists, companies and government agencies often assemble small
satellites without special precautions atop ordinary desks
and workbenches. Whether
chemical,
electrical or mechanical -- 'propellant' stored aboard these satellites
would represent a major safety hazard. Mainly for safety concerns,
propulsion systems are removed from consideration. In the process, a
host of mission possibilities are never seriously imagined.
What
about including propulsion to significantly alter an orbit? or to
sustain a high drag environment? or to perform rendezvous and docking,
or
station-keeping, or formation flying, or perhaps to later
bring
itself and
maybe a larger satellite safely down from orbit? What
about escaping from
orbit altogether, or autonomous satellite operations in orbit
around other planets? The
desktop environment is far too risky for those sorts of
propulsion engineering goals, and if truly a desired mission
objective, desktop
facilities must be
abandoned, sending the satellite's cost
into
orbit while the project often stays on the ground.
format,
specifically:
Without sufficient ∆V smaller spacecraft developers cannot hope to offer debris mitigation services, or multiple on-orbit inspection and repair missions, or even remotely consider interplanetary exploration and sample return flights.
In the absence of sufficient low-risk desktop-safe ∆V most microsatellites will remain relegated to modest missions flying close to home.
Our Response
Our workshop this year
focuses on propulsion systems built, integrated, fueled
and tested
safely without contemplating airtight hazmat suits or
concrete bunkers. Rather
then revolving around more
traditional trade-space anchors such as ISP, Desktop
∆V will
address key question such as:
-
What desktop-safe processes exist?
-
Of these, which technologies exist on scales we might apply to micro-spacecraft?
-
If required, could systems scale to a smaller size?
-
How might high ∆V propulsion systems integrate into form factors we would like to build?
-
Where are the roadblocks to development and application?
As
educators, we see the value
in propulsion designs more easily
explored by students pursuing the field. As engineers we further see
this leading
to
a
host practical
applications ranging from higher ∆V
nanosatellites to low
environmental impact planetary space vehicles.
The Audience is the Investigator
Our goal focuses on bringing those developing technologies together with those investigating applications.There is no audience per se. We are all co-collaborators.
As we facilitate the workshop, organizers will seek to stimulate a wide variety of presentations and panel discussions on topics relevant to the central subject of Desktop ∆V propulsion while avoiding excessive overlap.
To
cast our net widely, the following are examples of topical
areas under discussion
(by no means comprehensive):
- Where is work on Desktop ∆V happening? Who are the players?
- Description of missions that can most benefit from Desktop ∆V
- Project costs and benefits
versus larger-scale propulsion systems
- Special design and
fabrication
requirements (if any)
- In-flight spacecraft
performance capabilities
and limitations
- Unique maneuvering and
stabilization
methodologies
- How 'safe' is 'safe'?
- Missions made
possible -only- with safer thrusters
- "Killer app”
missions that might launch a Desktop ∆V
industry
- Science opportunities - near
earth - planetary - deep space
- When will we see new Desktop ∆V flight hardware in space?
Morning sessions will cover emerging technologies with key examples. Afternoon panel discussions will further explore notions of desktop safe propulsion systems and the realities of hardware engineering versus mission objectives.
Morning Presentations...
In the morning sessions,
prominent contributors to the field will present 20 minute executive
summaries of their work with
Q&A follow up. Topics will focus on Desktop ∆V
propulsion in areas such as technical enablers, architectural
concepts, operational logistics, development costs, and potential
missions.
Lunchtime
Poster Session...
Sharpe Refectory Chancellors Dining Room (map)
Participating students
will present a
lunchtime poster session immediately adjacent to the dining room.
Afternoon Panel Discussions...
The afternoon sessions will
feature
moderated panel discussions
among a
mix of system architects, technology experts, prospective sponsors
(commercial and government) and mission designers, with a strong
emphasis on audience participation.
The first session will discuss the nature of desktop safe propulsions
as actually practiced with the goal of identifying those with the most
promise of high ∆V propulsion.
The second afternoon session will brainstorm spacecraft concepts and
missions
addressing the best balance of desktop ∆V propulsion
applications and the sorts of vehicles that might best benefit from
this technology.
A table will be provided for those offering giveaway items representing your organization or any program related to Desktop ∆V propulsion.
Please let us know what you have in mind and we'll make sure to leave space for you.
PowerPoint Slide Presentation and Archive
Presenters are asked to bring PPT slides on a flash drive stick (please save as PPT or PPS - not PPTX or PPSX). All presentation slide files will be loaded into our presentation computer prior to the start of the workshop.Presentation slides will be available for download from this website before the close of the workshop. A permanent copy of slides will be hosted here for future reference.
If presenters have concerns about slide publication - please contact us prior to the workshop.
