Is Beagle 2 based on the original Beagle?

I was hoping they figured out what happened to the first Beagle. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

Beagle 2 crashed into mars. <div class="Discussion_UserSignature"> </div>

Parts of Beagle 1 may have been incorporated into a farm house. <img src="/images/icons/laugh.gif" />

I'm completely serious.<br />As for Beagle 2 being based of beagle 1.....<img src="/images/icons/rolleyes.gif" />

Is beagle 2 based on beagle1?

 

[tohaki]

Beagle 2 was the failed Mars lander. The original Beagle (HMS <i>Beagle</i>) was the ship that Charles Darwin used on his scientific expeditions.

I asked because I heard somewhere that there was a new Beagle being built. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

<font color="yellow">"...I heard somewhere that there was a new Beagle being built."</font><br /><br />That would be Beagle 3. <div class="Discussion_UserSignature"> </div>

 

[willpittenger]

The article mentions possible causes, but does not list what they are doing to protect Beagle 3 as those causes appear to be conjecture rather than analysis. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

You can only analyse the data you have. I don't think there was any data collection or link with Beagle 2 during its descent -- a result of flying on the cheap. I don't blame them. You do what you can with what you have. If it had landed safely what a great accomplishment it would have been. <div class="Discussion_UserSignature"> </div>

There was no such information for Mars Polar Lander. But they still found a cause somehow. Supposedly it shut its engine off too soon. Personally, if that was the case, what happened to the Deep Space 2 probes? The cruise stage for MPL was not designed to signal that everything successfully separated. So how do they know the separation happened at all? That would doom all three probes. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

Thinking about all these failed missions is a big downer.<img src="/images/icons/frown.gif" /> Luckly we have MER and, soon MRO in addition to the other working orbiters to keep us happy.<img src="/images/icons/smile.gif" /><br /><br />Post mortems of failed missions are necessary. They are interesting and depressing at the same time. I think there is reason to hope that all that has been learned from the failed as well as the successfull missions will ensure a near 100% success rate from this point on. <div class="Discussion_UserSignature"> </div>

 

[willpittenger]

I agree they are needed, but I do not understand how they reached those conclusions without any data. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

Looks like the Galactic Ghoul may remain well-fed.

 

[craig42]

Which One? There were a few. If you mean Cook's ship, it's supposedly moored on the river Thames near Greenwich IIRC.

<blockquote><font class="small">In reply to:</font><hr /><p>There was no such information for Mars Polar Lander.<p><hr /></p></p></blockquote><br /><br />Correct. It's still not 100% certain that the root cause was a premature engine cutoff due to an oversensitive touchdown sensor. The way they reached that conclusion was by analysis of the design and testing with spares still on Earth. They found that they could reproduce the hypothesized failure consistently enough to be confident that it would've done MPL in if nothing else went wrong.<br /><br />They tried to do a similar analysis with Beagle 2, but could find nothing so glaringly obvious in the design. In the end, they could reach no conclusions about the cause of the accident, although recent imagery suggests that it might merely have had the rotten luck to land on the side of a steep crater. (That's a calculated risk in any unmanned lander mission, because you simply can't aim the landing accurately enough to avoid all obstacles.)<br /> <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

Still, having the cruise stage report back that separation happened normally would help. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

 

[CalliArcale]

Definitely. Every little bit of data helps when trying to work out what happened in an accident.<br /><br />Some probes are able to communicate during their descent as well, which gives even more telemetry to work with. I guess it comes down to how much you can afford to stick on the spacecraft.<br /> <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

Like the MER landers? <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

They could afford such a communication system, but their mass allocation would not allow it. Needless to say the Beagle 2 team were deeply peeved to discover when it came to final integration with ME that there was something like 30 kg of margin that they could have used, had been for some time, and they had not been told about.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

 

[nacnud]

I didn't know about that. That must have been infuriating considering the lenghts they went to (airbags and parachute for example) to stay within their mass alocation.
