This NASA spacecraft will get closer to the sun than anything ever before

  This NASA spacecraft will get closer to the sun than anything ever before The Parker Solar Probe will launch this year en route to the sun's atmosphere — a mission 60 years in the making.With time, each of those dreams became a reality — the Hubble Space Telescope, the twin Voyager spacecraft, the Apollo program. All except one: an effort to get a close look at the sun, the source of Earth's light and heat, as well as solar storms that could disrupt our satellites and fry our electric grid.

(NASA) NASA confirmed an incredible discovery Tuesday — that an amateur radio astronomer, on the hunt for a classified government satellite, stumbled upon signals from a spacecraft that had been thought lost 12 years earlier, raising hope that NASA can resurrect a mission that changed our understanding of the “invisible ocean” around the Earth.

1. Lost

IMAGE was a machine designed to “see the invisible,” as one of the mission's lead scientists once put it.

It was a squat and boxy thing, like many satellites, with a long technical name — Imager for Magnetopause-to-Aurora Global Exploration — that obscured its plain and noble purpose: to map the roiling sphere of electric gas around the Earth that protects us from the sun, and which we had never seen in full before.

Clashing Chemicals Might Identify Distant Alien Life

  Clashing Chemicals Might Identify Distant Alien Life (Methane + carbon dioxide) - carbon monoxide = aliens?Chemicals such as oxygen are hard to produce without some kind of life. If a planet has oxygen in its atmosphere, it may very well harbor microbes. On Earth, however, oxygen has only been produced in large amounts for about an eighth of its history.

Before IMAGE launched in 2000, humans had known only for a few decades that a magnetosphere surrounded the planet. In an essay before the launch, the mission's lead investigator, James L. Burch, called it an “invisible ocean . . . where nothing tangible — no snow or sand or tree or even a cloud — records titanic currents and pulses.”

The sphere shields our planet from the sun's harsh winds, while letting through its light. Like an ocean, its plasma ripples and flows in a solar wind. But also like an ocean, it is prone to storms — solar disruptions so violent they can knock out satellites, and even power grids on Earth.

IMAGE was built, Burch wrote, to send home images of the global magnetosphere for the first time in history, and help predict those storms.

How to return a lost phone to its owner

  How to return a lost phone to its owner Do your good deed for the day. How can you identify the owner of a lost phone? However, most people lock their phone screens for security, so when you need to track down the owner, you can't simply fire up the Contacts app and start calling friends and family. Unless they printed their name and address in big letters on the back of the device, you'll have to rely on other methods to restore the lost phone. Here are some tips we came up with, including a few from this Reddit thread.

For five years, it astonished us.

The satellite beamed back pictures of an enormous solar storm in summer 2000, and allowed scientists to essentially live-stream “weather” in space. The sphere around the Earth proved to be a much stranger place than had been thought. IMAGE discovered that the Earth spits out jets of its own atmosphere to defend itself from space storms — like a squid shooting ink — the Dallas Morning News wrote in 2002. It discovered cracks in the Earth's magnetic field, tracked down the source of mysterious radiation, and imaged 100,000-volt charged particles whipping around the circumference of the globe.

The scientists tried to figure out why. A tripped breaker in the radio was their best guess. But without a radio, they couldn't tell it to turn itself back on.

After a month of silence from IMAGE, NASA published a news release that declared the satellite's mission a great success — one that was now over.

SpaceX launches satellite aboard Falcon 9 rocket

  SpaceX launches satellite aboard Falcon 9 rocket A SpaceX Falcon 9 rocket using a previously flown first stage shot away from Cape Canaveral Wednesday afternoon -- 60 years to the day after the first successful U.S. satellite launch -- boosting a commercially developed military relay station into orbit for Luxembourg, its NATO allies and satellite operator SES.It was the California rocket builder's sixth flight featuring a "used" booster, a key element in founder Elon Musk's drive to lower costs. It was the 48th flight of a Falcon 9 overall and the second so far this year.

“The craft's power supply subsystems failed,” the agency wrote, “rendering it lifeless.”

NASA was wrong. IMAGE was not dead, but it would circle Earth for more than a decade before a man with no professional astronomy training — one who did not always accept the official explanation of events — heard its call.

2. Contact

The 21st century moved into its second decade, and space exploration changed. New machines were sent into orbit, and some of them, like IMAGE, were lost too.

In the first month of 2018, an unknown government agency used a private company to launch a secret satellite, code-named “Zuma.” It was nothing like IMAGE; it was a machine intended to be invisible to most of the world.

And it failed immediately.

No one has said publicly what, exactly, went wrong during the Jan. 7 launch, whether Zuma crashed back into an ocean or simply died in space. Its fate and purpose have become a mystery of the new Space Age — and all of this bothered Scott Tilley very much.

Tilley is a 47-year-old electrical engineer who lives on the west coast of Canada. His hobby is radio astronomy. In a sense, it's also his cause.

Japan launches smallest rocket ever to carry satellite into orbit

  Japan launches smallest rocket ever to carry satellite into orbit Japan has set a new spaceflight record -- and unlike most of these feats, it's defined by what wasn't involved. The success came just over a year after JAXA's original experiment with an SS-520 rocket ended in failure. Crews decided against igniting the second stage when the vehicle lost all telemetry data a mere 20 seconds after takeoff. An investigation later determined that the likely cause was a poorly protected electrical connection, and the agency decided to try again this year with a fix in place.

“Space is not owned by anybody,” Tilley told The Washington Post. “Anybody should be able to look up and know those little dots moving across the night sky are not bombs.”

Secret military satellites and classified orbits bother him, so he has banded together with a small group of fellow amateurs across the world to to track down every satellite whose operators don't want it to be seen.

Maybe Zuma was in pieces at the bottom of an ocean, Tilley thought. But maybe not. So he began to scan. He used no telescope, listening instead for radio signals out there, in the invisible ocean.

When Tilley caught a signal after a week of searching, on Jan. 20, he almost ignored it. Whatever it was, it was orbiting much higher than Zuma was supposed to be. There are hundreds of active satellites in space, most of which didn't interest him.  “I didn't think of it much more,” he wrote on his blog.

But as he continued to scan for Zuma, he came across the signal again — stronger this time — and out of curiosity checked it against a standard catalogue.

The signal matched for IMAGE. But IMAGE was supposed to be dead.

Tilley had to Google the old satellite to find out what it was, as it had been all but forgotten on Earth. Eventually, he came across a decade-old NASA report on the mission's failure.

“Once I read through the failure report and all the geeky language the engineers use, I immediately understood what had happened,” Tilley told Canadian Broadcasting Corp. News.

That old news release announcing the death of IMAGE had not actually been the end of its story on Earth. A week later, in early 2006, NASA quietly convened a board of experts to pore over the satellite's entire data set and figure out what went wrong.

They worked for months. When their final report was released, the board still figured IMAGE had tripped a power breaker and essentially bricked itself, like a bad iPhone.

But they had come up with a theory for how the satellite might be fixed. Or rather how it might fix itself.

IMAGE was solar-powered, and designed so that if its battery ever drained enough, it would try to reset its computer and flip the breaker back. The board thought this was most likely to happen in late 2007, when IMAGE's orbit would put it in the Earth's shadow from the sun — from the satellite's point of view, a deep eclipse.

But the theory didn't pan out. When NASA tried to the contact IMAGE after the eclipse, it remained as silent as ever, so the agency closed down the mission for good.

And then, a decade later, Tilley found the machine chirping away.

After his discovery, another independent astronomer, Cees Bassa, looked for IMAGE's signal in years of old data. He hypothesized that while the 2007 eclipse didn't manage to reset the satellite, another one did the trick, probably some time between 2014 and 2016.

“Most likely the battery efficiency degraded such over the IMAGE lifetime that during the less deep eclipses the battery drained sufficiently to lead to the reset and bring the transmitter aboard IMAGE back to life,” Bassa wrote.

Scientists Recreate Titan’s Methane Ocean In Lab

  Scientists Recreate Titan’s Methane Ocean In Lab NASA plans to send an autonomous submarine to Saturn’s largest moon Titan to study the liquid methane oceans on its surface.To further the study of Titan, which NASA has been analyzing using data collected by the Cassini mission, scientists at Washington State University recreated a methane ocean in a laboratory. To be exact, the WSU researchers built a test chamber filled with a “liquid mixture at very cold temperatures to simulate the seas of Titan. They added a two-inch, cylinder-shaped cartridge heater that would approximate the heat that a submarine would create.

NASA hasn't confirmed that. In fact, the agency was initially skeptical that the signal Tilley found actually came from IMAGE.

After Tilley contacted NASA last week, scientists trained antennas at the Goddard Space Flight Center on the object. Initial tests showed its orbit, frequency, oscillation and spin rate all matched their old, lost satellite.

Even so, NASA was cautious in its public updates, writing Sunday that it still wanted to analyze the signal's encoded data before it could be sure.

Meanwhile, astronomers amateur and professional were getting excited. “The team is collectively holding their breath,” Patricia Reiff, an investigator on the original mission, told Science Magazine.

On his blog, Tilley quoted from an email sent to him by James L. Burch, the lead investigator on the IMAGE mission, who wrote so many years ago of a machine to map an invisible sea.

“Very excited,”  Burch wrote to Tilley.

Confirmation finally came Tuesday. It came couched in the technical jargon of space science, and was no less momentous for it.

“On the afternoon of Jan. 30, the Johns Hopkins Applied Physics Lab in Laurel, Maryland, successfully collected telemetry data from the satellite,” NASA wrote. “The signal showed that the space craft ID was 166 — the ID for IMAGE.

“The NASA team has been able to read some basic housekeeping data from the spacecraft, suggesting that at least the main control system is operational.”

Translation: There is hope that IMAGE will one day send more pictures of the “ocean” where it's been adrift for more than 12 years.

“I really hope the scientists who built this thing and put it in space are able to repurpose this and put it back into action,” Tilley told CBC. “And we get the benefit of all the beautiful science, coming home.”

He was named nowhere in NASA's news release, except as an anonymous “amateur astronomer.”

But that's fine. He found the thing, when the professionals might have left it lost forever.
