Rover data from more than 20 years ago has revealed clues to the existence of liquid water on ancient Mars. The NASA Spirit Rover carried a specialized instrument called a Mössbauer Spectrometer that performed mineralogical analyses of soil, rock, and dust on the surface of the Red Planet at Gusev Crater. Individual measurements didn't always indicate definitive proof of water, but when scientist Paolo de Souza of Edith Cowan University in Australia examined years' worth of measurements together, a definite pattern began to show up in the existence of minerals that could only exist in the presence of water. His analysis shows that Mars used to sport a lot more water than scientists expected and that the data showing its existence was in the data all along.
Cassini, NASA’s last major mission to Saturn, famously plunged to its fiery death in the gas giant’s atmosphere at the end of its mission. It had captured more accurate in-situ data of the Saturnian system than any mission before or since. But there’s one particular part that it couldn’t directly approach - Saturn’s rings. But NASA very obviously wants to take a nice up-close look at them, as they have recently funded a NASA Institute for Advanced Concepts (NIAC) Phase I grant to send a swarm of 10,000 highly expendable “femtosatellites” to get up close and personal with the most spectacular rings in our solar system.
Given the state of our technology, it would take a spacecraft a ridiculously long time to reach even the nearest star in our galaxy. However, scientists continue to ponder ways in which we could achieve the dream of interstellar spaceflight. Here are a few of their best ideas.
Scientists have captured images of the sun's surface in the finest detail yet, revealing a strange and dynamic facade. It's dangerous to look directly at the sun without proper eye protection. Scien...

While the collision was an accident, it is a unique scientific gift for planetary geologists that could provide important data for future space missions.
We have been watching asteroid (44) Nysa for well over a century without ever really knowing what it looks like. Now the sharpest images ever taken of it, from two of the largest telescopes on Earth, have revealed two deep valleys running right around its circumference and the team behind them think those are necks, joining three separate lobes into a single 75 kilometre body. If that holds up, Nysa is the first three lobed world we have ever found. And in the glare beside it the same observations turned up something nobody was looking for, a tiny moon a kilometre across, which may be the thing that settles the argument.
Pluto’s moon, Charon, is one of the most unexplored (and arguably underappreciated) planetary objects in the entire solar system. This is primarily because it’s only been visited once by NASA’s New Horizons spacecraft during its famous Pluto flyby in July 2015. Despite this quick encounter, New Horizons beamed back troves of data regarding Charon that scientists continue to pour over with the goal of gaining insight into Charon’s formation and evolution. This is because Charon is the largest moon compared to its parent body in the solar system, noted by it being half of Pluto’s diameter and one-eighth of Pluto’s mass.
During the Space Age and Cold War, fusion-powered spacecraft systems were investigated as a possible means of reaching another star system within a human lifetime. Many of the proposed ideas are still on the table today, waiting for future advancements to make them realizable.
The planet Mercury is the first planet from the Sun but also one shrouded in mystery. This is primarily due to the limited number of spacecrafts that have visited it, but this limited data has provided scientists with new and exciting characteristics previously thought impossible. One fascinating aspect is its magnetic field, which was first discovered in March 1974, which both surprised and puzzled scientists due to the planet’s small size, which is measured at about half the size of the continental United States from coast to coast.
On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki, respectively, during the final days of World War II. The aerial bombings killed 150,000 to 246,000 people, most of whom were civilians, and remain the first and only uses of nuclear weapons in an armed conflict.
Eighty-one years ago on Thursday, the United States dropped an atomic bomb on Hiroshima, reducing the city to ruins, killing tens of thousands of people and bringing the world “face to face with the catastrophic power of nuclear war”.

Papers note that repetitive DNA — the type of DNA that our junk-DNA-defending friends assure us must be functionless — is vital for forming G4 structures.
Europe is investing billions of euros in sovereign space infrastructure but industry leaders are warning that satellites alone will not be enough to secure long-term strategic autonomy.
They argue that Europe must also accelerate the deployment of optical (laser) communications if its future space networks are to remain competitive with foreign systems such as Space-X's Starlink, which already uses laser inter-satellite links to provide faster, more secure data transfer than conventional radio-frequency communications.

In the middle of Central Asia sits a desert full of shipwrecks, hundreds of miles from any coastline — rusting fishing boats stranded on cracked, dry seabed where one of the world's largest lakes used to be, before Soviet planners diverted the rivers that fed it
A row of rusting fishing trawlers sits on cracked sand outside Moynaq, in the far west of Uzbekistan, bows still aimed at a horizon that has not held water in decades. Camels pick their way between the hulls. Kids climb the wheelhouses. The nearest shoreline sits more than 100 kilometres away, across a salt flat that used to be seabed.
Relentless heat and a dearth of rain is having a punishing effect on some of Europe’s most vital rivers, which have tumbled to record lows in place, threatening energy production, shipping and tourism.

The planet Neptune has 16 known moons, with its largest Moon, Triton, comprising more than 99.5 percent of the mass of all of them. Triton’s incredible size has led scientists to hypothesize it was a captured object originating from the Kuiper Belt, which wreaked havoc on Neptune’s original moon system upon its capture and subsequential elliptical orbit. Today, some remnants of these original moons are part of the dusty rings that orbit Neptune. But what did that original moon system consist of? Were they the same small worlds observed today or are they pieces of what was once much larger worlds?
There are a number of things in the Universe that could wipe out life as we know it, but — for now, and for Earth — a blast from our galaxy's supermassive black hole isn't one of them. That's not to say that Sagittarius A* doesn't pose a danger. If it wakes up someday and blasts out a strong wind, that definitely could affect Earth. It could well have powered a quasar in the past, and could do so again.
Most of us are familiar with Betelgeuse (also known as alpha Orionis), the bright shoulder star in the constellation Orion. It's a red supergiant star that lies somewhere between 400 and 550 light-years away from us and is quite bright. Betelgeuse contains about 14 times the mass of the Sun and is a fairly young star compared to ours. It appears to be no more than 10 million years old, which means that it evolved rapidly from a protostar to the red giant we see today. That lifecycle means Betelgeuse will explode as a supernova sometime in the relatively near future — say within the next 100,000 years.

Scientists at the Lowell Observatory in Flagstaff, Arizona report they detected a plume from the impact August 5 from that errant SpaceX rocket stage.
“We can safely say that we measured a response from the rocket stage impact as a sodium and lithium gas plume a few 10’s of kilometers in size lasting between 5 and 10 minutes after impact,” Carl Schmidt tells Inside Outer Space.

How does a spacecraft launched in 1977, now more than 25 billion kilometres from home, still transmit data back to Earth on less power than a household hallway bulb?
Voyager 1 is transmitting from 25 billion kilometres away on a 22-watt radio — less power than a hallway bulb — thanks to decaying plutonium, a 3.7-metre dish, and 70-metre antennas on Earth listening for a signal that takes nearly a full day to arrive.
