The word is, the last three sols (1730-1732) were all 160-170Whrs power, with actual useage being >20Whrs LESS than that - so entirely power positive.

It seems nomenclature of planets outside our solar system is as prone to emotion as those within it.

Consider it on the banned subjects list as of now. Find another board to have semantic arguments on off-topic subjects.

What they are, is unworthy of discussion at UMSF. Move on.

5m/pixel isn't going to do anything amazing for surface hardware, except with long shadows. We've got 50cm/pixel coming next year anyway.

You dismiss the challenges of actually landing on Venus for several weeks with "this is a very fixable issue"

Might I suggest you move to this thread - http://www.unmannedspaceflight.com/index.php?showtopic=1118 - and explain away the challenges over there.

Hence why I'm printing the two halves of Tayfun's great projections as 16cm squares, to make a 32cm circumference (thus just over 10cm diameter) sphere :0

t wouldn't it be simpler to create some thin metal/composite encapsulation around the rover


Simpler to somehow get a large lid off the rover after landing? I don't think so. It would be a lot heavier, it would mean the rover having to withstand the mass of the rover AND the descent stage on its suspension thus reducing margin on performance for landing.

The rope-rappel may seem crazy - but it's a lot less crazy and a lot safer for the rover than many other options.

There are videos out there somewhere of some rappel tests- but for the life of me I can't find them again.

How fast was it travelling? According to that link, it hit the moon at 1.6 KM / Hr.


Not hour. SECOND.

Doug, where did you get that realistic terrestrial globe with clouds and all? I've been after one of those for years.


The imaginative 'just globes' ( http://www.justglobes.co.uk/ )

It's actually about as good as I was expecting, and if it gets enough light, populated areas then glow in the dark smile.gif

I'll do photos when I've made my scale Moon to go with it smile.gif

Huge thanks to Tayfun - those are AWESOME!!!

Does anyone recall the last location where Spirit had a cleaning event, and how far away that was?


The Eastern side of home plate. All of 20m away.

1709 looks like 95m SE - onto the edge of a large area of pavement. I've tacked a guess onto Tesh's 1707 map, but leave it to him to do a proper version for the route map thread.

That I don't know. I'm guessing 1729.

1730 has a sequenced Tau in it which is good news.

Most may be due to turned off heaters.


No. Whrs = power generated. Heaters are one of a number of ways of consuming that power. What you do with the power doesn't change how much of it you actually get in the first place. Whrs are how many pennys get put in the jar. Heaters are one of a number of ways of taking them out again.

And scrap 140whrs....she was on 161.

(Just a reminder every now and again.)


Here's a reminder. UMSF Rule 2.4

- 2.4 Don't rant. If you have a point to make...make it and move on. Do not litter your every post making the same point again and again. If you want somewhere to vent - get yourself a blog.

Official forum ruling...

... it doesn't matter what you call we as long as we know what people mean. Skycrane, descent stage, Rupert the Rocket, Piggyback Propellant Part, Dave the Decelerator. Having heard Richard Cook use both names within a single lecture, semantic debate over what it should or shouldn't be used is pointless. And we know what the media will call it - so anyone who continues to object, will have a LOT of objecting to do over the next 2 years. As 2.4 states, however, they can do it somewhere else. There's factual inaccuracy ( which this isn't ) and there's semantics ( which this is ).

What I've heard is approx 140whrs, and has not tripped a low power fault.

The Doug analysis - in the ICU, but not on the critical list.
