7 earth size planets orbiting same star!!

^ Expect it to cost too much and do too little for too short a time to be useful to anyone

 

Supposedly, the JWST is going to be launched to the Earth–Sun L2 point using an Ariane 5 ECA in October 2018. The design life span is 5 years with a goal life span of 10 years.

 

I got an update on my Droid that one of planets TRAPPIST - d might be habitable.

Is anyone able to confirm this update?

 

If they are tidally locked, and assuming they had an atmosphere to circulate heat, might the far-side of these planets be shielded from solar flares?


Yes, I want them to be habitable damn it. Tell me what I want to hear!

 

The rest of the universe screams "get your hot Jupiters"

Meanwhile this cat-lady star hoards all the Earth sized planets in one system

greedy little red dwarf

 

It took them 15 years to build it and it'll only be operational for 5 to 10 years?

 

Seems crazy perhaps but it's often the case for space missions to have a much longer preparation time than mission time. At least they now appear to be committed to launching the thing. The Ariane 5 ECA has been used previously to launch to the Earth–Sun L2 point (Herschel and Planck) and to deep space (Rosetta). The JWST is only a little more massive (6.5 tonnes at launch) than Herschel and Planck (5.5 tonnes). Herschel and Planck lasted about 4 years before the coolant in their Dewars ran out -- the design lifetime was 3.5 years. The JWST doesn't use a Dewar for cooling; instead it uses a combination of a sun shield, radiators and a cryocooler.

And unlike Hubble--there will be no servicing this thing. What I want is a simple monolithic mirror telescope like ATLAST--but I want that in LEO so we can make it last--maybe have it co-orbiting with ISS. Standard docking port in its tail so you can slide boxes in and out--no spacewalks.

I have this sneaking suspicion that Webb is going to do like the mesh antenna on the Galileo probe and seize up half-way through deployment. Too many parts packed too tight due to the existing shroud diameters. That's your LV biting you.

Ariane 5 as Asbo Zaprudder said. SLS will be for ATLAST

Our commitment to simplicity is based on the analysis of David Beardon. Beardon has shown that there is a direct correlation between mission payload complexity and total mission cost...Given the available mass and volume capacity of the SLS, some subsystems may be able to use simpler more-mature (and more massive) technologies or higher design rule margins to eliminate complexity, lower risk and lower cost."

Which completely debunks the statement made here:
"ATLAST would be worse than JWST. The folding telescope was not the cost driver for JWST."

Oh well--not everybody sees things the same way

Something just occurred to me.

The Space Launch System--SLS looks to fly in the Trump administration.

Great--now there's two loud orange things everyone hates.'

Try the baked fish--and everybody remember to tip your waiter on the way out.


On an unrelated note---If I had to find the location for Trek's planet Vulcan--I'd put it here, not at 40 Eridani A

Now for some beer from the Trappist Monks...

 

I believe the estimated age of the TRAPPIST-1 system is currently about 1 Ga so perhaps not really long enough to develop multicellular life never mind an advanced civilisation. However, estimating stellar age is not an exact science.

 

We always assumed that the Romulans split off from their homeworld on Vulcan. A good twist would be bor both to have started as Mintakans who moved on.

 

With a mass 24 times that of the Sun, the main star in the Mintaka multiple star system can be no more than about 3.5 million years old. Of course, the Mintaka in Trek might not be Delta Orionis.

 

The Mintakans could be transplanted there by the preservers or whatever.
And the planet itself could be terraformed.

 

It could be possible that more of the planets of TRAPPIST might be able to support life and do in fact support life because of their relative closeness to each other.

[SIZE=5]Absolute Zero[/SIZE]
The key defining characteristic of outer space is emptiness. Matter in space concentrates into astronomical bodies. The space between these bodies is truly empty -- a near-vacuum where individual atoms may be many miles apart. Heat is the transfer of energy from atom to atom. Under outer space conditions, almost no energy is transferred because of the vast distances involved. The average temperature of empty space between celestial bodies is calculated at 3 kelvins (minus 270.15 degrees Celsius or minus 457.87 degrees Fahrenheit). Absolute zero, the temperature at which absolutely all activity stops, is zero kelvins (minus 273.15 degrees Celsius or minus 459.67 degrees Fahrenheit).

Therefore two bodies in space that are close together are more likely to share or transfer their energies back and forth between the each allowing for a more diverse environment to be created.

With the planets of TRAPPIST -1 being rather close to each the energy from Trappist -1 could basically "jump" between the the inner planets when the inner planets are all in alignment giving each planet an energetic boost that would power flora and fauna that would only bloom when the planets were in alignment.

Animal and Mammal life and even microbial life could also hibernate during the non-alignment phases of the inner planets.When the inner planets of TRAPPIST-1 align and the energy transfer increase they would emerge from their hibernation to take in the extra energy and then go back into hibernation once the alignment phase had cycled.

During the planets normal orbits around TRAPPIST-1 life would function normally with numerous microbes gathering and storing the abundant source of energy that would be used to sustain the flowers and fauna for the next alignment phase cycle.

The question however is this. Is the temperature in space around the inner planets similar to Earth's that is a balmy 50.3 degrees Fahrenheit? If the temperature in space around each planet can be tested and is comparable to Earth's space temperature then an atmosphere similar to Earth's might be present on the planet.


[SIZE=5]Near Earth[/SIZE]
The average temperature of outer space around the Earth is a balmy 283.32 kelvins (10.17 degrees Celsius or 50.3 degrees Fahrenheit). This is obviously a far cry from more distant space's 3 kelvins above absolute zero. But this relatively mild average masks unbelievably extreme temperature swings. Just past Earth's upper atmosphere, the number of gas molecules drops precipitously to nearly zero, as does pressure. This means there is almost no matter to transfer energy -- but also no matter to buffer direct radiation streaming from the sun. This solar radiation heats the space near Earth to 393.15 kelvins (120 degrees Celsius or 248 degrees Fahrenheit) or higher, while shaded objects plummet to temperatures lower than 173.5 kelvins (minus 100 degrees Celsius or minus 148 degrees Fahrenheit).

Was this in the constellation of Aquarius?

I wish we had some kind of sublight tech or cryosleep. It would be awesome.

Oh and I'm an aquarian

 

We have lots of sublight tech. All of it really slow.

 

I know, I mean something like impulse drive.

What kind of speeds could that do on Trek?

 

Whatever the plot required.

 

Ah, so true...... So true.
