SpaceX, the aerospace company founded by Elon Musk, is working diligently on a wildly ambitious project: to permanently settle people on Mars. To help make that vision a reality, Musk’s company is developing a colossal, fully reusable launch system called Starship. Starship is envisioned as a 180-foot-tall spaceship that will ride into orbit atop Super Heavy, a

WASHINGTON — NASA has selected for development a mission that will perform a spectroscopic survey of the entire sky at near-infrared wavelengths to study the origins of solar systems, galaxies and the universe. The agency said in a Feb. 13 statement that it picked Spectro-Photometer for the History of the Universe, Epoch of Reionization and
There’s been a recent increase globally in outbreaks of vaccine-preventable diseases. This can be seen in recent measles outbreaks in parts of the world where it was thought to have been eradicated. This has prompted the World Health Organisation to list “vaccine hesitancy” (the reluctance or refusal to vaccinate despite the availability of vaccines) as
Sirius, a double-star system and the brightest object in the night sky, will briefly blink out of existence for parts of Earth on Monday evening. In an event called an occultation – when one object in space blocks the light of another behind it – a small asteroid known as (4388) Jürgenstock will slip in front of the
It is clear that climate is changing, and there is a human component on top of the naturally varying system. Most climate scientists understand this, and most logical people do too. The 4th National Climate Assessment report is a good place to find affirmation for these statements. Each year, the Yale Climate Communication group and
WASHINGTON — Fleet Space Technologies will begin raising money next week from investors in a Series A financing round after service launch immediately filled its four cubesats with customers. The Internet of Things (IoT) startup based in Adelaide, Australia, logged 1 million devices in 24 hours, with customer applications ranging from monitoring beehives to oil pipelines,
The life of a sperm isn’t easy. From cervix to egg, the female reproductive tract puts these tiny swimmers through an obstacle course of doom. It’s like being forced into a haunted house where the only way out is forward. At every turn there are more ways to die: bathed in acid, tangled in mucus, attacked
Most of us have been caught out by weather forecasts that didn’t quite turn out as predicted, but today’s sophisticated models can make reasonably decent guesses up to 10 days in advance. Now a newly developed computing technique promises to push that limit out even further. If the system fulfils its initial promise, we could

For twent million years, the world’s oceans were home to a monstrous shark, named the ‘megalodon’. Then suddenly, without explanation, the 18-metre-long (50 foot) super predator disappeared. It’s a juicy bit of ancient history that has inspired a host of books, documentaries and blockbuster films, some of which like to imagine that this bloody thirsty
There’s an old saying, “When you reach the end of your rope, tie a knot in it and hang on.” In other words, before you give up, take matters into your own hands and try a little harder. As a psychology researcher, I believe this adage applies to relationships, too. Before you let go, look
The Great Barrier Reef just can’t catch a break. Year after year, this global treasure has been battered by cyclones and beaten by bleaching events. Now, with little time to recover, a part of the reef is being kicked while its down. An exceptional year of rainfall in Queensland, Australia has caused a huge flood
China’s Academy of Space Technology is working on an orbital power plant that would capture solar energy in space and beam it back to Earth. The plant would be able to harness solar power even when it’s cloudy back on Earth, since its photovoltaic array would be floating high above any terrestrial weather. With plans to
The waters surrounding Seal Island in False Bay, South Africa are eerily calm. All you can hear are waves lapping up against your boat, and you can feel a tension in the air as everyone waits for a moment made famous by Shark Week. Suddenly, there is commotion on one side of the boat as
Early warning and communications satellites that support the NC3 system are vulnerable to electronic attacks and interference. WASHINGTON — A new report released on Thursday on Capitol Hill makes the case for billions of dollars in investments in the nation’s nuclear command, control and communications network known as NC3. The report was co-produced by the
Deep in the Watagans Mountain Range in Australia, a red-eyed green tree frog (Litoria chloris) had bitten off much more than it could chew. Its dinner was to be an unassuming red triangle slug (Triboniophorus graeffei); instead, the frog ended up covered in a sticky mucus and completely stuck to a tree branch. Researchers from
Long-duration spaceflight does weird things to the human body, even at the molecular level, but so far there’s no reason to think humans couldn’t survive a two-and-a-half-year round-trip journey to Mars. That was the bottom-line message Friday from a NASA official and two scientists as they revealed more results from the agency’s “Twins Study,” which
