1. The Meridiani Journal - Boating on Titan: new mission proposal for exploring an alien lake
2. Nextbigfuture - Europe is proposing a space boat to explore Saturn's moon Titan. The new plans, called the Titan Lake In-situ Sampling Propelled Explorer, proposes a boat-probe, propelled by wheels, paddles or screws. The probe would land in the middle of Ligeia Mare (the biggest lake, near Titan’s north pole), then set sail for the coast, taking scientific measurements along the way. The mission would last around six months to a year.
"The main innovation in TALISE is the propulsion system," says Igone Urdampilleta (SENER) of the TALISE team. "This allows the probe to move, under control, from the landing site in the lake, to the closest shore.

10. Nextbigfuture - . Keith Lofstrom wants to put huge number of miniature, solar powered servers (called thinsats) in orbit. This concept, known as "server sky", would be facilitated by a low-cost launch system referred to as "Launch Loop". This loop could put many thousands of tons into space at a small fraction of the cost of using rockets. In an interview with Sander Olson for Next Big Future, Lofstrom describes how the server-sky concept could greatly reduce the need for ground-based data centers, and how Launch Loop might be the best solution to opening up space.
11. Nextbigfuture - The Z-Pinch dense plasma focus method is a Magneto-Inertial Fusion (MIF) approach that may potentially lead to a small, low cost fusion reactor/engine assembly 1. Recent advancements in experimental and theoretical understanding of this concept suggest favorable scaling of fusion power output yield 2. The magnetic field resulting from the large current compresses the plasma to fusion conditions, and this process can be pulsed over short timescales (micro-second). This type of plasma formation is widely used in the field of Nuclear Weapons Effects testing in the defense industry, as well as in fusion energy research. A Decade Module 2 (DM2), ~500 KJ pulsed-power is coming to the RSA Aerophysics Lab managed by UAHuntsville in January, 2012.
The analysis of the Z-Pinch MIF propulsion system concludes that a 40-fold increase of Isp over chemical propulsion is predicted. An Isp of 19,400 sec and thrust of 3800 N-sec/pulse, along with nearly doubling the predicted payload mass fraction, warrants further development of enabling technologies.

13. Nextbigfuture has excerpts from Warp Field Mechanics 101. This is a 33 page document on the NASA servers with a paper and presentation.
Almost all of the information in this post is from the Harold White paper "Warp Field Mechanics 101" and a presentation he made on September, 2011 at the 100 Year Starship Symposium which were all posted at the NASA server. The original Alcubierre space warp theories required massive amounts of energy and exotic matter. If Harold White is correct with his ideas for a higher dimension manifold and thicker shell, then the amount of energies needed will come down to a feasible level. Experiments at NASA over the next few months with a moderate sized laser could show that a detectable space warp is formed with 1 ten millionth the level of warping than would be needed for actual propulsion.

14. Nextbigfuture - Plasma magnetoshell aerobraking is a NASA NIAC phase 1 study project . Any breaking drag forces on the Magnetoshell will be three orders of magnitude larger than the aerodynamic forces on the spacecraft. Magnetoshell should be one thousand times better than aerobraking.
The recent Mars Curiosity rover mission required a skylift rocket landing system because the one ton rover was too big for aerobraking on Mars. Plasma magnetoshell aerobraking could enable far less mass for stopping and landing on planet and other missions.
