In October 2017, the interstellar object ‘Oumuamua passed through our Solar System, leaving a lot of questions in its wake. Not only was it the first object of its kind ever to be observed, but the limited data astronomers obtained as it shot out of our Solar System left them all scratching their heads. Even today, almost five years after this interstellar visitor made its flyby, scientists are still uncertain about its true nature and origins. In the end, the only way to get some real answers from ‘Oumuamua is to catch up with it.
Interestingly enough, there are many proposals on the table for missions that could do just that. Consider Project Lyra, a proposal by the Institute for Interstellar Studies (i4is) that would rely on advanced propulsions technology to rendezvous with interstellar objects (ISOs) and study them. According to their latest study, if their mission concept launched in 2028 and performed a complex Jupiter Oberth Manoeuvre (JOM), it would be able to catch up to ‘Oumuamua in 26 years.

Scientists’ detailed study of the Moon dates back to the Apollo missions when astronauts brought rock samples from the lunar surface back to Earth for analysis. Apollo 11 gathered samples from the lunar highland regions, the pale areas on the Moon’s surface easily seen from Earth. The highlands are made of a relatively light rock called (2) REPLACEMENT BULBS FOR USHIO 1000731 1500W 208V, which formed early in the history of the Moon, between 4.3 and 4.5 billion years ago.
There’s some mystery involved in the anorthosite formation on the Moon. The age of the anorthosite highlands doesn’t match how long it took for the Barwalt 81520 Tile Flooring Grout Sponge with Handle to cool. But scientists behind a new study think they’ve solved that mystery.

The production company that’s playing a key role in a space movie project involving Tom Cruise says it’s working with EGT K-Type Thermocouple Exhaust Probe High-Temperature Sensors 1 to add a sports and entertainment facility to the International Space Station by the end of 2024.
The inflatable module, known as SEE-1, would be built by Axiom for Space Entertainment Enterprise and attached to the commercial complex that Axiom is already planning to put on the space station, SEE said in a Jan. 20 news release.
The facility would provide a studio for film, TV and music production as well as a space for performances and sports events. “SEE-1 is an incredible opportunity for humanity to move into a different realm and start an exciting new chapter in space,” said SEE’s co-founders, Dmitry and Elena Lesnevsky.

Data from the Cassini mission keeps fuelling discoveries. The latest discovery is that Saturn’s tiny moon Mimas may have an internal ocean. If it does, the moon joins a growing list of natural satellites in our Solar System that may harbour liquid water under their surfaces.

The HiRISE (High-Resolution Imaging Science Experiment) camera on the Mars Reconnaissance Orbiter has captured another beauty. This time the image shows water ice peeking out from a cliffside on Mars. A layer of sediment obscures most of the ice, but fingers of it are visible.

We often think of supernova explosions as inevitable for large stars. Big star runs out of fuel, gravity collapses its core and BOOM! But astronomers have long thought at least one type of large star didn’t end with a supernova. Known as Wolf-Rayet stars, they were thought to end with a quiet collapse of their core into a black hole. But a new discovery finds they might become supernovae after all.

It’s really true: space wants to kill us. And this time, space is trying to kill us from the inside out.
A new study on astronauts living on board the International Space Station shows that while in space, the astronauts’ bodies destroyed 54 percent more red blood cells than they normally would on Earth. Even one year after their flight and back on Earth, the symptoms of “space anemia” persisted in the 14 astronauts tested.

As any good cardiologist would tell you, blood flow is key to your health. They probably won’t tell you that gravity is key to blood flow. But that’s probably because they don’t usually have to deal with patients that aren’t subject to gravity. When people are no longer subject to gravity, such as astronauts resident on the ISS, that lack of gravity can become a problem, especially when dealing with sensitive soft tissues such as the eyes. To solve that problem, a team of scientists and engineers have the University of Texas Southwestern have developed a special type of sleeping bag that might help astronauts with their blood flow issues caused by gravity, and potentially get their sight back.

In the coming years, NASA will be making the long-awaited return to the Moon, where they will be joined by multiple space agencies and commercial partners. This will be followed by NASA and China sending the first crewed missions to Mars and other locations in deep space in the next decade. This presents numerous challenges, not the least of which involves providing for astronauts’ basic needs while in flight. In keeping with the tradition of “solving for space solves for Earth,” dedicated to addressing air-quality problems and Climate Change here at home.
To help NASA address these problems, the leading crowdsourcing platform HeroX has launched two new incentive challenges. First, there’s the “Waste to Base Materials Challenge: Sustainable Reprocessing in Space,” which seeks innovative solutions for what to do about all the waste that’s generated during long-duration spaceflights. (human and otherwise). Second, there’s the “NASA Air-athon Challenge,” which is looking to foster high-resolution air quality information to improve public health and safety.

Astronomers have spied three more exoplanets. But the discovery might not last long. Each planet is in a separate solar system, and each orbits perilously close to its star. Even worse, all of the stars are dying.
Three doomed planets.
