The tilted image below shows the rover’s dire condition. Sloped at a roughly 20¨ angle, Spirit’s wheels are deeply entrenched in the sand. Luckily, Spirit’s chassis appears to be free from major obstructions, giving some hope to crews working out a rescue plan.

Engineers at NASA’s Jet Propulsion Lab are studying the images to develop a plan that will free the ailing rover. This isn’t the first time a mars rover has become stuck. In 2005, Spirit’s twin rover, Opportunity, became disabled by the sand. Opportunity’s foray with powdery martian sand resulted in a month of downtime before slow forward progress inched her into the clear.

Another tactic for removing sand imprisoned mars rovers is to back up the rover out of the martian sand trap on the same path it went in. It is unlikely, however, that engineers will reverse Spirit out of the sand trap. In 2006, Spirit’s front right wheel permanently jammed. Since then, Spirit has operated in reverse, dragging her jammed wheel — making backing up out of her sandy tomb a difficult task.

This news comes after a rough year for the rover. Last year, budget concerns resulted in an attempt to shut down the rover project as we know it. Recently, Spirit underwent a bout of amnesia, and could not report what it had recently done. Engineers were also worried about a possible lock-up in one of Spirit’s middle wheels, which a reassuring roll test suggested no problem existed. One can only be thankful that the rovers have lasted almost 1900 days past their 90 day planned mission.

Orbital Express Satellite

A retired Russian General has claimed the ‘accidental crash’ between a Russian and US Iridium communications satellite was no accident. According to Maj. Gen. (Ret.) Leonid Shershnev, former head of Russian military space intelligence, the crash may really be a conspiracy – a US ploy to test the feasibility of controlling or disabling hostile satellites.  Source: Official Russian State-owned  News  and Information Agency – RIAN

You may have heard about this supposed “test” already (Above at RIAN, HERE on robots.net, and many other places on the ‘net I’m too lazy to link to). If not, you’ve probably at least heard that two satellites collided, leaving a ton of dangerous debris.

Does anyone else question the credibility of a Russian General (ret.) talking about a US conspiracy to take out foreign satellites in the State-owned Russian news agency? If you don’t, you probably should. This sounds like nothing but Russian propaganda, to me. For the hearing impared, it smells and looks like it, too.

Sure, a loosely related DARPA program may have existed, but let’s not take their state-owned word for it when they say the program’s purpose was to go out and destroy other satellites.

We’d probably never know for sure if it really was a secret US Military test. Remember,  just because the odds were long doesn’t make it impossible. It makes it unlikely. Sometimes unlikely things happen.
