InSight is scheduled to land on Mars at 11:53 am PST (19:53 UK) on Monday, November 26.

The Mars Polar Lander, first lander of that type, was lost on January 3, 1999 (Thanks, Lockheed Martin!).


Phoenix landed in 2008 has a moderate success, finding ice. But the scoop couldn't deliver sample to the tools... It worked for 10 months.


With luck, InSight will dramatically increase these statistics - the landing ones and the longevity. The primary mission is two years, the team is hoping for much more. Good luck to InSight!

farawayred i love your posts in this thread. on a totally unrelated note i like a podcast from STUFF YOU SHOULD KNOW called "the end of the world" by josh. first episode about "the fermi paradox", and second one about "the great filter". havent listened to the rest yet but i'll get around to them soon.

Cheers, mate!

Forgot to add something about InSight. There is a period between entering the atmosphere and landing that we call "7 min of terror". During that time we have no clue what's going on with the spacecraft and whether the landing was successful. For the first time we may fill that information gap. There are two cube sats, WALL-E and Eva, which are intended to provide real-time information about the InSight EDL. Would be so much fun if we get an actual video of the landing!

This is awesome, mate, thanks for posting!

Exciting times are coming ahead... JPL is jam-packed with media from this evening, we've been encouraged to take the day off or work remotely (so I spent the long Thanksgiving weekend in my lab). Hopefully, the landing will go to plan, I'll be watching with family and friends.

Should all go to plan, instrument deployment would be interesting too. I can't wait to see marsquake data. I'm no longer working on the project, but if the vacuum in the seismometer doesn't hold up, you can hold me responsible. I'm sure it will though. It should actually have much better vacuum than initially planned, which will give the science team the chance to detect 10-100 times weaker quakes. This will overload them with data. :)

I haven't been involved with the mole after the redesign in 2016. The original one used to dig deep than it came up on its own... :) Surprises are part and parcel of the work... and that's what makes it exciting!

The InSight science is really cool too, but the seismometer is just an incredibly smartly designed engineering marvel! Think about it, on Earth we detect where an earthquake is coming from because we have a network of seismometers all over the globe and we do triangulation. On Mars, we have one instrument, one point. Yet, we can determine the origin! And the planetary structure. If anyone is interested, I could go in more details (though I'm not a seismologist).

Or Marvin the Martian on Curiosity... except they'd need an SEM to find it... ;D

Maybe the Russians will take a look, but first they have to check if the Americans actually landed on the Moon. ;)

It was freaking cool!... We are now closing on the 50-50 chance of successful landing! ;D (19 successful, 20 unsuccessful)

A good article on BBC:
https://www.bbc.com/news/science-environment-46351114

Tom Hoffman, the project manager, is pretty happy:



It's too early to say, but it seems that we've been incredibly lucky with the landing spot - flat and rock-free. Perfect place for both the seismometer and the mole. Much to do, solar panels, instrument deployment... But so far, so good.

The best thing about this picture is this - look at the rock clear field near the rover versus the rock field from nearby all the way to the horizon! The seismologists are ecstatic!

I wonder if the booster rockets as it landed cleared the area.

No, I don't believe so. Maybe the jets cleared the small centimeter-sized ones, but they can't move a 20-cm rock like those on the background.

But you know what JPL stand for, right? Just Plain Lucky. ;D

Wut?


https://www.sciencealert.com/microbes-on-the-iss-show-we-can-t-take-astronaut-health-for-granted


Antibiotic-Resistant Bacteria Have Been Discovered on Board The International Space Station


An uninvited guest has been caught hitching a ride on the International Space Station, and it's a worrying one. JPL-NASA Scientists have identified strains of Enterobacter collected from the space station's toilet and exercise area.

If you've heard of the genus before, it's probably in relation to hospitals. Some Enterobacter strains can infect immunocompromised patients in intensive care wards - and they have high resistance to antibiotics.

Luckily, the strains of Enterobacter found on the ISS were strains that aren't pathogenic to humans, but the fact that there were any strains of Enterobacter on the station at all could have worrying implications.

Human bodies are positively teeming with (beneficial) microbes. We trail them wherever we go; and, even using our best sterilisation methods, we can't entirely eradicate them on spacecraft in clean rooms. So it would be incredibly surprising if there weren't any at all aboard the International Space Station.

But it's an environment unlike any found on Earth. There's microgravity, there's space radiation, there are elevated carbon dioxide levels, and there's the constant presence of humans, all of which could affect the way microbes live and propagate.

Microbiologists with NASA's Jet Propulsion Laboratory regularly analyse microbe samples collected from the space station to see if the space environment affects their populations in any way - and also to see if they are posing a hazard either to the health of the astronauts, or the delicate equipment.

But this is the first time they've identified antibiotic-resistant Enterobacter strains up there.

"To show which species of the bacteria were present on the ISS, we used various methods to characterise their genomes in detail. We revealed that genomes of the five ISS Enterobacter strains were genetically most similar to three strains newly found on Earth," explained microbioligist Kasthuri Venkateswaran.

"These three strains belonged to one species of the bacteria, called Enterobacter bugandensis, which had been found to cause disease in neonates and a compromised patient, who were admitted to three different hospitals (in east Africa, Washington state and Colorado)."

The samples were collected in 2015, and no astronauts have been struck down by an Enterobacter, so the microbes don't seem to be an immediate danger.

But, in the future, they could pose one. The researchers compared their antibiotic resistance to that of the three clinical strains, and found that the space Enterobacter were resistant to cefazolin, cefoxitin, oxacillin, penicillin and rifampin, and had varying degrees of resistance to others.

They also found that, while the space station Enterobacter strains aren't currently human-pathogenic, they have 112 genes in common with the clinical strains, associated with virulence, disease and defense.

According to computer modelling, there is a 79 percent probability that they will develop into a human pathogen, and cause disease.

This is yet to be tested in living organisms, and we do need to reiterate that currently, the astronauts are safe from infection by these particular strains. But the discovery does warrant further investigation and, possibly, a way for residents of the space station to deal with antibiotic-resistant diseases.

"Whether or not an opportunistic pathogen like E. bugandensis causes disease and how much of a threat it is, depends on a variety of factors, including environmental ones," Venkateswaran said.

"Further in vivo studies are needed to discern the impact that conditions on the ISS, such as microgravity, other space, and spacecraft-related factors, may have on pathogenicity and virulence."

The team's research has been published in the journal BMC Microbiology.

In the midst of all this InSight hoo haa ;) let us not forget that our old friend New Horizons is just a month away from a historic close encounter with a KBO - the furthest object in the solar system ever to be explored up close and personal; and the first object to be explored that wasn't discovered until after the explorer had been sent.
