Well prepare to get sadder . . . :\

The Mars rover Curiosity has temporarily ceased work as engineers investigate what appears to be a short circuit in its electrical system.

The space agency said Tuesday that the electrical problem was discovered over the weekend as Curiosity tried to transfer bits of powder from a rock that it had drilled into. The short circuit stopped the rover’s robotic arm. Engineers are diagnosing the issue, and the testing is expected to take several days.

The worrisome components of this story are the words “short circuit” and “drill”, because of a known design flaw in the electrical system of the rover’s drill. It could very well be that this flaw, which could cause a short that could bring down the rover, is the cause of this electrical problem.

Early today Orbital ATK successfully completed a two minute test firing of its five segment solid rocket booster, the largest solid rocket motor ever built and intended for NASA’s SLS rocket.

Feel the power kiddies . . . :cool:

And in other news, looks like Atlas 5 is going to launch tonight from Cape Canaveral's Complex 41 for liftoff Thursday night to deploy four NASA satellites that will probe Earth's magnetosphere for a high-priority research project. The Magnetospheric Multiscale mission, or MMS is slated for 10:44 p.m. EDT on Thursday, at the opening of a 30-minute window. . . . :tup:

I wonder how long it will be until we can have a camera like this in our smartphones ;)

Funding approved for 3200-megapixel Large Synoptic Survey Telescope
SLAC National Accelerator Laboratory Press Release

When LSST starts taking images of the entire visible southern sky in 2022, it will produce the widest, deepest and fastest views of the night sky ever observed. Over a 10-year time frame, LSST will image several tens of billions of objects and create movies of the sky with unprecedented detail. Image credit: Large Synoptic Survey Telescope Project Office

Plans for the construction of the world’s largest digital camera at the Department of Energy’s SLAC National Accelerator Laboratory have reached a major milestone. The 3200-megapixel centerpiece of the Large Synoptic Survey Telescope (LSST), which will provide unprecedented details of the universe and help address some of its biggest mysteries, has received key “Critical Decision 2” approval from the DOE.
“This important decision endorses the camera fabrication budget that we proposed,” said LSST Director Steven Kahn. “Together with the construction funding we received from the National Science Foundation in August, it is now clear that LSST will have the support it needs to be completed on schedule.”

Science operations are scheduled to begin in 2022 with LSST taking digital images of the entire visible southern sky every few nights from atop a mountain called Cerro Pachón in Chile. It will produce the widest, deepest and fastest views of the night sky ever observed. Over a 10-year time frame, the observatory will detect tens of billions of objects — the first time a telescope will catalogue more objects in the universe than there are people on Earth — and will create movies of the sky with details that have never been seen before.

Elon Musk is at it again . . . Watch tomorrow as SpaceX launches a resupply Falcon 9 rocket to ISS at about 4:33 EDT and will once again try to land the first stage on the Autonomous Spaceport Drone Ship. I say again, if they pull this off, it will revolutionize space travel by reducing costs.

Live broadcast for launch should be on NASA TV. Here the Dragon resupply capsule is being readied for launch . . .

Well the Falcon 9 is on its way to the ISS, HOWEVER, it looks like the first stage hit the Autonomous Spaceport Drone Ship but hit it hard. The video should be interesting when it surfaces and I will of course post it here if I can . . .

SpaceX chief executive Elon Musk says the Falcon 9 booster made a hard landing on the drone ship in the Atlantic Ocean.

"Ascent successful. Dragon enroute to Space Station. Rocket landed on droneship, but too hard for survival," Musk posted on Twitter.

Video of Falcon 9 first stage landing attempt. The footage is looped so you can watch today’s landing attempt several times in a row. It is once again astonishing that the rocket hits the target, but it is coming down very fast, and not very vertical. Like the Grasshopper tests, they need to slow it down more just before landing.

SpaceX targets May 5 for Dragon pad abort test . . . SpaceX as soon as May 5 will shoot a Dragon capsule from Cape Canaveral in a test of a key safety system needed for astronaut launches in the next two or three years.

The so-called "pad abort" test will launch a prototype crew spacecraft from a stand at Cape Canaveral Air Force Station's Launch Complex 40, simulating a launch pad emergency.

The Dragon will fire SuperDraco thrusters designed to enable the capsule and its crew to escape from a rocket failing on the pad or during flight.

And in other news . . .

Rosetta records the appearance of a new jet on Comet 67P/C-G . . . Images taken two minutes apart by Rosetta have captured the emergence of a new jet on Comet 67P/C-G. You can see the new jet appear on the darker bottom in this GIF.

Chinese scientists just admitted to tweaking the genes of human embryos for the first time in history


Nishimasu et al, 2014)The genome-editing enzyme known as CAS9 at work on a strand of DNA.

A group of Chinese scientists just reported that they modified the genome of human embryos, something that has never been done in the history of the world, according to a report in Nature News.

A recent biotech discovery — one that has been called the biggest biotech discovery of the century — showed how scientists might be able to modify a human genome when that genome was still just in an embryo.

This could change not only the genetic material of a person, but could also change the DNA they pass on, removing "bad" genetic codes (and potentially adding "good" ones) and taking an active hand in evolution.

Yeah, the Russians screwed that one up good. Wrong orbit, tumbling, no deployment of antennas, a total cluster fuck. I guess the astronauts on ISS will just have to make do without those supplies. People are watching for reentry of this craft but they really don't know when or where it will hit the atmosphere. Be interesting to see if anyone gets any video of the burn . . .

WARNING: This object is expected to decay around Sun, 10/05/2015 05:20:00 +/- 84 hours UTC (these predictions are provided by Joseph Remis).
