This has been reported before and was probably even linked in a different thread, but IFL's summary is short and easy to understand.
I've seen similar reports from a couple of other pop science sources, possibly just repeating and amplifying one another. The gist is that NASA might be getting ready to announce warp bubbles, but for now they're busy making sure because we all remember how cold fusion and FTL neutrons turned out.AWS260 wrote:I'm gonna go out on a limb and speculate that no, they didn't.

The SuperNova Early Warning System (SNEWS) is a network of neutrino detectors designed to give early warning to astronomers in the event of a supernova in our home galaxy or a nearby galaxy such as the Large Magellanic Cloud or the Canis Major Dwarf Galaxy. Enormous numbers of neutrinos are produced in the core of a red giant star as it collapses on itself. In the current model the neutrinos are emitted well before the light from the supernova peaks, so in principle neutrino detectors could give advance warning to astronomers that a supernova has occurred and may soon be visible. The neutrino pulse from supernova 1987A arrived 3 hours before the associated photons – but SNEWS was not yet active and it was not recognised as a supernova event until after the photons arrived.
Yeah, the science team and all the operations folks are sad to see it end, as am I. Here at the Applied Physics Lab they've proclaimed tomorrow as MESSENGER day to celebrate the end of the mission.AWS260 wrote:Messenger is in her final days.See you later, Pahinui Crater.The New York Times wrote:NASA’s Messenger spacecraft, in orbit around Mercury the past four years, will come to an abrupt end on Thursday.

An unmanned Russian spacecraft loaded with supplies for the International Space Station is spinning out of control and is expected to plunge into the Earth's atmosphere next week, the Russian space agency said Wednesday, according to the local media.
The Progress spacecraft, carrying food, fuel, oxygen and scientific equipment, was launched on Tuesday but ran into immediate trouble, ending up in the wrong orbit in an uncontrolled spin, the TASS news agency reports.
The space agency failed repeatedly in attempts to communicate with the Progress.
Without radio control from the ground, the space agency could neither be put into proper orbit, 257 miles above the Earth, nor stop it spinning.
...
Roscosmos said the craft is expected to drop out of orbit and plunge into the atmosphere between May 5 and 7, Tass said, quoting the space agency's press service.
Only a small amount of debris is likely to hit the Earth after the craft largely burns up.
Therefore, the discovery that laser beams may have just breached the speed of light sent the page into discussions on the long-term implications of warp speed bubbles and the possibly of future warp speed travel.
First, the researchers note that though beams that were shot into the EmDrive were recorded at speeds faster than light, there is still one more study that must be performed to determine with certainty that the light speed barrier was broken. Scientists note that the beams must be shot through the EmDrive in a vacuum environment. This will ensure that the effect was not a result of atmospheric heating.
“I don’t think we can call this length contraction (even though it might look like it) for sure until the same results are in repeated in vacuum.”
Commenters note that the whole finding was one big accident and that researchers did not even realize that the EmDrive was replicating a well-known physicist’s theory of warp bubbles.
“That’s the big surprise. This signature (the interference pattern) on the EmDrive looks just like what a warp bubble looks like. And the math behind the warp bubble apparently matches the interference pattern found in the EmDrive. Seems to have been an accidental connection. They were wondering where this ‘thrust’ might be coming from. One scientists proposed that maybe it’s a warp of the spacetime foam, which is causing the thrust.”

A group at NASA’s Johnson Space Center has successfully tested an electromagnetic (EM) propulsion drive in a vacuum – a major breakthrough for a multi-year international effort comprising several competing research teams. Thrust measurements of the EM Drive defy classical physics’ expectations that such a closed (microwave) cavity should be unusable for space propulsion because of the law of conservation of momentum...
...The scientific community met these NASA tests with skepticism and a number of physicists proposed that the measured thrust force in the US, UK, and China tests was more likely due to (external to the EM Drive cavity) natural thermal convection currents arising from microwave heating (internal to the EM Drive cavity).
However, Paul March, an engineer at NASA Eagleworks, recently reported in NASASpaceFlight.com’s forum (on a thread now over 500,000 views) that NASA has successfully tested their EM Drive in a hard vacuum – the first time any organization has reported such a successful test.

Astronomers at the Keck Observatory in Hawaii are scratching their heads after finding a group of four quasars, a gathering that current cosmological thinking rates as a ten million-to-one chance of occurring.
"If you discover something which, according to current scientific wisdom should be extremely improbable, you can come to one of two conclusions: either you just got very lucky, or you need to modify your theory," said Joseph Hennawi of the Max Planck Institute for Astronomy. "Extremely rare events have the power to overturn long-standing theories."
Quasi-stellar-objects, or quasars, are thought to be extremely rare phenomena that occur when enough matter falls into the accretion disc around a supermassive black hole to generate enormous energy.
The four newly discovered quasars were spotted around 10 billion light years away in a giant nebula of cool dense hydrogen gas that has been irradiated by its quartet of high-energy inhabitants. The whole group is part of an unusually large galactic cluster that caught astronomers' attention.
...
One possible explanation is that the quasars formed when two galaxies collided a few billion years after the Big Bang. It's thought that the resultant matter could fuel black holes and lead to the quasar signals, but more research is needed.
A Russian rocket carrying a Mexican satellite has malfunctioned and burnt up over Siberia soon after launch on Saturday, Russia's space agency says.

A Russian rocket carrying a Mexican satellite has malfunctioned and burnt up over Siberia soon after launch on Saturday, Russia's space agency says.
The Proton-M carrier rocket broke down minutes after it was launched from Kazakhstan on Saturday morning, the Roscosmos agency said.
By pure coincidence, Viktor Vekselberg has a new satellite. Pure coincidence."There has been a malfunction on board the booster rocket. This broadcast is now over," the presenter said.

Space industry sources say that the Mexican satellite has not been found and launches of Proton-type rockets will be grounded until the reason for the malfunction is established.
It's not responding to reboot commands, so their best hope is that a random charged particle will cause a spontaneous hard reboot, which is apparently relatively common.Late Friday, the LightSail team received a heads-up warning them of the vulnerability. A fix was quickly devised to prevent the spacecraft from crashing, and it was scheduled to be uploaded during the next ground station pass. But before that happened, LightSail’s automated chirps fell silent. The last data packet received from the spacecraft was May 22 at 21:31 UTC (5:31 p.m. EDT).
BBC.com wrote:The European Space Agency (Esa) says its comet lander, Philae, has woken up and contacted Earth. Philae, the first spacecraft to land on a comet, was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November. It worked for 60 hours before its solar-powered battery ran flat. The comet has since moved nearer to the Sun and Philae has enough power to work again, says the BBC's science correspondent Jonathan Amos. An account linked to the probe tweeted the message, "Hello Earth! Can you hear me?" On its blog, Esa said Philae had contacted Earth, via Rosetta, for 85 seconds on Saturday in the first contact since going into hibernation in November.
Communication with the spacecraft is via X band. The craft had a communication rate of 38 kbit/s at Jupiter; at Pluto's distance, a rate of approximately 1 kbit/s is expected. Besides the low bandwidth, Pluto's distance also causes a (one-way) latency of about 4.5 hours.
