Kerbal Space Program – A visual history of ‘career mode’ from John Walker

September 19, 2015 TopSpacer

John Walker, founder of Autodesk, Inc. and co-author of AutoCAD, has posted a big Screenshot Gallery obtained from running Kerbal Space Program and learning a whole lot about rockets, orbital mechanics, and other aspects of spaceflight : New: Kerbal Space Program Screenshot Gallery – Fourmilog: None Dare Call It Reason.

The images were

accumulated over a several-months-long play-through in career mode which unlocked the entire technology tree and visited every body in the Kerbol system. An introduction explains the basics of the game to those unacquainted with it. I will add to the archive as adventures continue.

And

One thing which is certain is that after you’ve spent some time with Kerbal Space Program you will develop an intuition about orbital mechanics which few people, even authors of “hard” science fiction, have. Here is how Randall Munroe, creator of xkcd, described it.

‘Cosmonauts: Birth of the Space Age’ – London Science Museum exhibit

September 19, 2015 TopSpacer

The Science Museum in London is hosting an exhibition on the early Soviet space program: Cosmonauts: Birth of the Space Age.

The Science Museum YouTube channel has several videos related to the exhibition. Examples include:

The first woman in space, Valentina Tereshkova, visited the exhibition and participated in an on-stage interview:

NASA opens student competition for designs of inflatable heat shields

An announcement from NASA:

NASA Seeks Big Ideas from Students for Inflatable Heat Shield Tech

NASA is giving university and college students an opportunity to be part of the agency’s journey to Mars with the Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge.

NASA’s Game Changing Development Program (GCD), managed by the agency’s Space Technology Mission Directorate in Washington, and the National Institute of Aerospace (NIA) are seeking innovative ideas for generating lift using inflatable spacecraft heat shields or hypersonic inflatable aerodynamic decelerator (HIAD) technology.

“NASA is currently developing and flight testing HIADs — a new class of relatively lightweight deployable aeroshells that could safely deliver more than 22 tons to the surface of Mars,” said Steve Gaddis, GCD manager at NASA’s Langley Research Center in Hampton, Virginia. “A crewed spacecraft landing on Mars would weigh between 15 and 30 tons.”

The NASA’s Mars Curiosity rover is the heaviest payload ever landed on the Red Planet — weighing in at only one ton. To slow a vehicle carrying a significantly heavier payload through the thin Martian atmosphere and safely land it on the surface is a significant challenge. NASA is addressing this challenge through the development of large aeroshells that can provide enough aerodynamic drag to decelerate and deliver larger payloads. HIAD technology is a leading idea because these kinds of aeroshells can also generate lift, which would allow the agency to potentially do different kinds of missions.

Interested teams of three to five undergraduate and/or graduate students are asked to submit white papers describing their concepts by Nov. 15. Concepts may employ new approaches such as shape morphing and pneumatic actuation to dynamically alter the HIAD inflatable structure.

Selected teams will continue in the competition by submitting in the spring of 2016 full technical papers on the concept. Up to four teams will present their concepts to a panel of NASA judges at the BIG Idea Forum at Langley in April 2016.

Each finalist team will receive a $6,000 stipend to assist with full participation in the forum. BIG Idea Challenge winners will receive offers ofpaid internships with the GCD team at Langley, where they can potentially work toward a flight test of their concept.
