On January 14, 2005, a spacecraft about 9 feet wide, with a mass of about 700 pounds entered the atmosphere of Titan, Saturn’s largest moon. Over the next two and a half hours, the Huygens probe, as the spacecraft was known, would report data from its descent through the thick atmosphere of Titan to the orbiting Cassini spacecraft above, and back to Earth. It also returned an image and data from the surface.

During the 1970’s, David Bowie sang about Ziggy Stardust and the spiders from Mars. If Tethers Unlimited has its way, the Red Planet will be crawling with them.

Earlier this month, NASA selected the Bothell, Washington-based company for a small business award to work on its Sensing and Positioning in Deep Environments with Retrieval (SPIDER) surface exploration system.

The Bio-inspired Ray for Extreme Environments and Zonal Exploration (BREEZE) combines inflatable structures with bio-inspired kinematics to create a highly efficient flier to explore the Venus atmosphere. This flier would take data while below the main cloud layer at approximately 50 km and re-charge using solar panels in the middle atmosphere at approximately 60+ km.

Tensioning cables would control the volume to allow the craft to rise and fall in the atmosphere. The bio-inspired kinematics will maximize flight efficiency while allowing a so-far unattained degree of control for a small inflatable flier in the upper atmosphere of Venus.

Descent probe or lander power is a key resource for planetary exploration, and is a particular challenge where solar power is difficult to utilize efficiently and alternative power sources are expensive, risky, or complex. Short duration, battery powered probes have successfully landed and returned data from the surfaces of cloud-shrouded Venus.

PARIS (NASA PR) — Data from NASA’s Cassini spacecraft has revealed what appear to be giant dust storms in equatorial regions of Saturn’s moon Titan. The discovery, described in a paper published on Sept. 24 in Nature Geoscience, makes Titan the third Solar System body, in addition to Earth and Mars, where dust storms have been observed.

The observation is helping scientists to better understand the fascinating and dynamic environment of Saturn’s largest moon.

PASADENA, Calif. (NASA/JPL/Caltech PR) — These six infrared images of Saturn’s moon Titan represent some of the clearest, most seamless-looking global views of the icy moon’s surface produced so far. The views were created using 13 years of data acquired by the Visual and Infrared Mapping Spectrometer (VIMS) instrument on board NASA’s Cassini spacecraft. The images are the result of a focused effort to smoothly combine data from the multitude of different observations VIMS made under a wide variety of lighting and viewing conditions over the course of Cassini’s mission.

Busek Company Selected for NASA Funding to Develop Spacecraft Advanced Propulsion

Busek Company will develop advanced CubeSat propulsion and Hall Effect thrusters (HETs) with the help of NASA funding.

The space agency has selected the Massachusetts-based company for five Small Business Innovation Research (SBIR) Phase 1 awards. The contracts are worth up to $125,000 apiece over 13 months.

The three proposals focused on CubeSats and small satellites include:

  • a low impulse bit electrospray thruster control system;
  • a compact high performance plasma propulsion system (CHPPPS); and,
  • an iodine-compatible photocathode for RF ion thrusters.

I realize it’s a bit late, but here’s a look back at the major developments in space in 2017.

I know that I’m probably forgetting something, or several somethings or someones. Fortunately, I have eagle-eyed readers who really seem to enjoy telling me just how much I’ve screwed up. Some of them a little too much….

So, have at it!  Do your worst, eagle-eyed readers!
